Researchers at The University of Manchester's have now achieved the first atomic‑resolution imaging of monolayer transition metal diiodides, made possible by creating graphene‑sealed TEM samples that prevent these highly reactive materials from degrading on contact with air. The study, published in , demonstrates that fully encapsulating the crystals in graphene preserves atomically clean interfaces and extends their usable lifetime from seconds to months. This capability arises from refinements to an inorganic stamp transfer approach the team previously developed and reported in , which provided the basis for producing stable, hermetically sealed samples.

“Working with these materials felt impossible at first as they are completely destroyed after a few seconds air exposure, preventing traditional fabrication approaches.” explained Dr Wendong Wang who has worked on developing the transfer technique and fabricated the samples in question. “Our approach protects samples r without any unnecessary transfer stages. Being able to make samples that can survive not just hours but months, and for international transfer between facilities, solves a major bottleneck in 2D materials research.“

“Once we were able to make stable samples, we were able to make several interesting observations about these materials, including identifying extensive local structural variations for the thinnest samples, atomic defect dynamics and edge structure evolution”, states Dr Gareth Tainton who conducted the TEM imaging and analysis as part of this work. “The structures of 2D materials are closely linked to their properties, and so being able to directly observe not only the structures of the different crystals, from monolayers up to bulk thicknesses, but also defect behaviour will hopefully inform further work on these materials to unlock their potential in technology”

“What excites me most is how this opens up previously inaccessible scientific territory. We've known theoretically that many reactive 2D materials have exceptional properties for electronics, optoelectronics, and quantum applications, but we couldn't get stable samples into the lab to test those predictions", commented Prof Roman Gorbachev of the National Graphene Institute, who led the investigation. 

This research was published in the journal ACS Nano.

The study, led by The University of Manchester, suggests that while removing livestock from upland grasslands can increase fast-cycling carbon stored in plants and dead vegetation, it can also lead to losses of a more stable form of soil carbon. This long-lived carbon, known as mineral-associated organic carbon (MAOC), is bound to soil minerals and can persist for decades to centuries, making it critical for long-term climate mitigation.

Grasslands store around one-third of the world’s terrestrial carbon, with the vast majority being found in soils. As governments pursue net-zero targets, removing livestock from historically grazed grasslands has increasingly been proposed as a scalable climate solution.

Traditionally, scientists and land managers have relied on “total carbon stocks” to assess carbon removal projects. However, the new findings, published in the today, show that focusing solely on the total amount of carbon stored, rather than how securely it is stored, may be misleading.

“While ungrazed grasslands tend to accumulate more unprotected carbon in plants and litter, they are associated with lower levels of soil carbon protected by minerals, which is the form most resistant to warming-induced decomposition,” explained Dr Luhong Zhou, lead author of the study and visiting scholar at The University of Manchester. “Although high grazing intensity can negatively affect soil carbon, our results show that total grazer exclusion does not necessarily lead to greater long-term soil carbon storage.”

The team of researchers from The University of Manchester (UK), Lancaster University (UK), Yale University (USA), Fujian Normal University (China), and Leiden University (the Netherlands), analysed 12 upland grassland sites across an 800-kilometre south–north gradient in the United Kingdom, from Dartmoor to Glensaugh in Scotland. At each site, they compared grasslands that had been ungrazed for more than ten years with neighbouring areas that had been grazed over that time.

They found that ungrazed grasslands tended to accumulate more short-lived carbon in plant biomass and surface litter but generally contained lower levels of MAOC.

The decline in long-lived soil carbon is linked to changes in vegetation following the removal of grazing sheep. As a result, grass-dominated landscapes are increasingly replaced by dwarf shrubs such as heather. The roots of the shrubs form associations with a specialised fungi called ericoid mycorrhiza. These fungi slow the decay of plant litter, causing an increase in production of short-lived carbon but also stimulating the breakdown of older, more stable soil carbon, in order to gain nutrients to sustain plant growth. Wetter soils can also further weaken the minerals that normally help protect MAOC.

“Viewing grazer removal as a universally beneficial strategy for carbon mitigation often overlooks the continuum of carbon durability within ecosystems, and the fact that not all carbon gains contribute equally to long-term climate mitigation,” said Dr Shangshi Liu from the Yale Center for Natural Carbon Capture who co-led this study. “ When slow-cycling carbon declines, grassland carbon stocks may become more vulnerable to future climate change. Effective climate mitigation strategies must therefore consider  both how much carbon is stored and how durable it is”

The findings come at a critical time for environmental management policy in the UK and globally, as governments develop land-use frameworks to meet net-zero targets.  

Professor Richard Bardgett, Chair of Ecology at Lancaster University, who initiated the study while at The University of Manchester, said: “Our results suggest that maintaining low-intensity grazing in upland grasslands, which cover large areas in the United Kingdom, is important for protecting the most stable forms of soil carbon.”

The authors emphasise that their findings do not argue against reducing overgrazing. Rather, they call for more balanced grassland management approaches that account for both total carbon stocks and carbon persistence.

The study was funded by the UK Natural Environment Research Council (NERC), the Biotechnology and Biological Sciences Research Council (BBSRC), the European Research Council (ERC), and Yale Center for Natural Carbon Capture fellowship.

The findings are Published in PNAS

Her achievement have also recently been marked by the award of the 2026 Hannes Alfven Medal by the European Physical Society, a prestigious international distinction recognising her “outstanding and innovative work bridging astrophysical and laboratory plasmas using analytical insights and modelling.”

Professor Browning joined what was then the University of Manchester Institute of Science and Technology (UMIST) in 1985 as a lecturer at the age of 25, following a mathematics degree at the University of Cambridge and a PhD at the University of St Andrews.

Her career has been marked by a series of significant firsts, starting by entering Selwyn College at the University of Cambridge aged just 16 - two or three years younger than most undergraduates – and in the first year that the college admitted women.

Following her PhD and post-doc in Scotland, she moved to UMIST for her first lecturing role, where she was the only female lecturer and one of just three female academics across the science and technology disciplines. She was promoted to professor in 2009.

Reflecting on those early days, Professor Browning said that a lack of role models made it difficult for women to imagine reaching senior academic positions.

“As a woman, you didn’t really think you were going to become a professor because there were so few role models,” she said. “I was lucky to have very supportive male colleagues, but it was still difficult. Often, particularly in fusion research, I could be the only woman in the room.”

Her interest in astrophysics began in childhood, sparked by an early fascination with the moon and by watching the Apollo moon landings. While she initially pursued mathematics, that curiosity about space ultimately drew her back into astrophysics.

Over the course of her career, Professor Browning has built an international reputation in plasma physics. Her work has focused on understanding how hot, ionised gases behave and interact with magnetic fields - processes that underpin solar flares, space weather and the development of future fusion energy.

Her early research at 91ֱ�� helped pioneer the spherical tokamak, an innovative approach to magnetic confinement fusion. Philippa’s team at 91ֱ�� was among the first to develop this compact alternative to traditional ring‑shaped fusion devices, an approach that has since become central to international fusion research and now underpins the UK’s government‑backed STEP fusion energy programme.

Alongside her research, Professor Browning has been a committed teacher, supervising around 19 PhD students and teaching generations of undergraduates.

“I’ve always really enjoyed teaching,” she said. “The interaction with students, particularly in small groups, is something I’ll really miss.”

During her time at the University, Professor Browning witnessed significant institutional change, most notably the merger of UMIST and the Victoria University of Manchester. While the department grew from a small, close‑knit unit into a much larger one, she reflects that students themselves have remained much the same where their curiosity, ability and enthusiasm have always varied across a spectrum.

She has also played a significant role in University leadership and service, serving on Senate and the Board of Governors, and holding a range of departmental roles including postgraduate director and admissions tutor.

A long‑standing advocate for equality in science, Professor Browning has been heavily involved in national efforts to support women in physics. She served on the Institute of Physics’ Women in Physics and diversity committees, helping to deliver training, networking events and outreach activities in schools to improve visibility and role models for girls.

She balanced her academic career with raising her son and two step‑children at a time when childcare support was far more limited. She was involved in campaigning for and establishing the first UMIST nursery, with her son among the first children to attend.

Her achievements have been widely recognised. She is a  recipient of the Royal Astronomical  Society’s Chapman Medal for outstanding research in solar and space physics, and a Fellow of the Institute of Physics. As mentioned above, she is now due to receive the European Physical Society’s Hannes Alfvén Prize for plasma physics, a senior international award recognising her lifetime achievements in the field.

As she retires, Professor Browning will continue her research as Professor Emerita and remain active in public engagement, including talks and events at Jodrell Bank Observatory.

“Retirement feels emotional,” she said. “My identity has been so tied up with the University for so long. But I’m looking forward to having more time for music and walking and just seeing what comes next.”

Professor Browning’s department will mark her retirement with a special event, ‘Pipfest’, bringing together former colleagues and PhD students from across her career.

This new discovery captures the cosmic moment when a galaxy cluster – among the largest structures in the universe – started to assemble only about a billion years after the big bang, one or two billion years earlier than previously thought possible. This result, made using NASA’s Chandra X-ray Observatory and James Webb Space Telescope,  is described in a paper published today (28 January) in the journal 

The findings will require astronomers to rethink when and how the largest structures in the universe formed. 

 “This may be the most distant confirmed protocluster ever seen,” said Akos Bogdan of the Center for Astrophysics | Harvard & Smithsonian (CfA) who led the new Nature study. “JADES-ID1 is giving us new evidence that the universe was in a huge hurry to grow up.”

The object is known as JADES-ID1 for its location in the “JWST Advanced Deep Extragalactic Survey”, or JADES. It has a mass about 20 trillion times that of the Sun. Astronomers classify JADES-ID1 as a “protocluster” because it is currently undergoing an early, violent phase of formation and will one day turn into a galaxy cluster.  

This object was first discovered and reported in an  led by The University of Manchester’s Qiong Li using deep JWST data, which was published last year  in the Monthly Notices of the Royal Astronomical Society. 

JADES-ID1 is found at a much larger distance – corresponding to a much earlier time in the universe – than astronomers expected for such systems, providing a new mystery of how something so massive could form so quickly.

Galaxy clusters contain hundreds or even thousands of individual galaxies immersed in enormous pools of superheated gas, along with large amounts of unseen dark matter. Astronomers use galaxy clusters to measure the expansion of the universe and the roles of dark energy and dark matter, among other important cosmic studies.

“It’s very important to actually see when and how galaxy clusters grow,” said co-author Gerrit Schellenberger, also of CfA. “It’s like watching an assembly line make a car, rather than just trying to figure out how a car works by looking at the finished product.”

The Chandra and Webb data reveal that JADES-ID1 contains the two properties that confirm the presence of a protocluster: a large number of galaxies held together by gravity. Webb sees at least 66 potential members that are also sitting in a huge cloud of hot gas detected by Chandra. As a galaxy cluster forms, gas falls inward and is heated by shock waves, reaching temperatures of millions of degrees and glowing in X-rays.

What makes JADES-ID1 exceptional is the remarkably early time when it appears in cosmic history. Most models of the universe predict that there likely would not be enough time and a large enough density of galaxies for a protocluster of this size to form only a billion years after the big bang. The previous record holder for a protocluster with X-ray emission is seen much later, about three billion years after the big bang.

This is yet another sign that structure in the universe is forming much quicker than astronomers had anticipated. 

After billions of years JADES-ID1 should evolve from a protocluster into a massive galaxy cluster like those we see much closer to Earth.

To find JADES-ID1, astronomers combined deep observations from both Chandra and Webb. By design, the JADES field overlaps with the Chandra Deep Field South, the site of the deepest X-ray observation ever conducted. This field is thus one of the few in the entire sky where a discovery such as this could be made. 

In an earlier study, a team of researchers led by Li and Professor Conselice at The University of Manchester found five other proto-cluster candidates in the JADES field, but only in JADES-ID1 are the galaxies embedded in hot gas. Thus, only JADES-ID1 possesses enough mass for an X-ray signal from hot gas to be expected. 

NASA's Marshall Space Flight Center in Huntsville, Alabama, manages the Chandra program. The Smithsonian Astrophysical Observatory's Chandra X-ray Center controls science operations from Cambridge, Massachusetts, and flight operations from Burlington, Massachusetts.  The JWST work was sponsored by the European Research Council in an Advanced Grant (EPOCHS) to The University of Manchester.

The study, led by The University of Manchester, offers a rare glimpse into a period of evolution that is usually extremely difficult to study because early vertebrates had soft bodies, so any remains are usually squashed, incomplete, or difficult to interpret.

Using a synchrotron particle accelerator, the Stanford Synchrotron Radiation Lightsource (SSRL) at SLAC  National Accelerator Laboratory in California, USA, the researchers were able to map the chemistry within two tiny jawless fish called Jamoytius and Lasanius, found near Lesmahagow, south of Glasgow.

The findings, published today in , represent a huge advance in our understanding of the early stages in the development of the vertebrate lineage.

 “We decided that transitional fossils, from one of the earliest stages of vertebrate evolution, would be perfect to look at with our new methods,” explained researcher , Professor of Geochemistry at The University of Manchester. “What we were able to discover was far beyond our expectations. Not only did we identify early bone structures deep in the geological record, but we also captured the first-ever images of some of the oldest camera-type eyes. These eyes preserve even the small notch where the optic nerve connected - features that form the basis of modern vertebrate eyes today.”

University of Manchester researcher , added: “It’s been amazing to see just how much new information we can recover from fossils which are usually too poorly preserved to be useful using these new technologies. Our findings help resolve scientific debates that have been running since the Victorian era. They point to a very early origin of bones and eyes in vertebrate history, probably even predating the group appearing altogether.

“I’m also excited because these fossils are most likely the ancestors of modern lamprey and hagfish, which now lack many of these features, so we’re adding to a growing body of work that shows those organisms have a far more complex evolutionary history than previously thought.”

Synchrotron X-ray Fluorescence imaging works by scanning a sample in front of the intense X-ray beam generated by the synchrotron particle accelerator. The X-rays cause atoms in the sample to emit their own X-rays (X-ray fluorescence), which the scanning system detects. The properties of the fluoresced X-rays are specific to the chemical element they originated from. As such, this technique can be used to identify and map tiny differences in chemical elements locked inside fossils and in some cases, the chemical remnants of tissues no longer visible with visible light.

Dr Nick Edwards, a Staff Engineer for the X-ray Fluorescence Imaging beam lines at SSRL, performed the X-ray imaging experiments as part of a long-standing collaboration with The University of Manchester research team, with whom he worked with for his PhD studies.

He said: “Synchrotron X-ray Fluorescence imaging is a versatile technique with advantages over other types of scientific analysis that make it amenable to studying fossils. The experiments do not need special environmental conditions, and we can place relatively large objects in the instrument without the need to remove material from them. We can detect the extremely low levels of elements present in biological systems and correlate them to specific fossil tissues in a matter of hours. The results from these fossils are fascinating and further corroborate that the chemistry of extinct organisms can be preserved over huge geological time scales and be useful in interpreting the evolution of life.”

In this study, the team found traces of zinc and copper that revealed the structure of the retina and pigment layer in the ancient eyes. They also found calcium and phosphorus showing where early bone-like tissue was present.

The research has been praised internationally. Dr Pierre Gueriau of the University of Lausanne, who was not involved in the research, said: “This study not only rewrites some chapters of the evolutionary history of our early vertebrate ancestors, but also illustrates how advanced fossil imaging is not limited to CT scanning and encompasses a suite of analytical chemistry methods capable of revealing a new range of information, in some cases even considered lost to fossilisation. This is truly an exciting time to be a palaeontologist”.

Corresponding author , a palaeobiologist at The University of Manchester, added: “I love these fossil fish. They may have been dead for over 400 million years but they keep on surprising us with new hidden data about our deep origins.”

The team will now continue using this high-energy physics technology to tease out the chemical remnants of early life in other vertebrates, providing key insights into the evolution of animals such as birds, dinosaurs, mammals, and even microbial life.

Today, the red kangaroo is the largest living hopping animal and weighs around 90kg. But during the Ice Age, some kangaroos grew more than twice the size of that - some reaching up to 250kg.

For years, researchers believed these giants must have abandoned hopping, as earlier studies suggested that hopping would become mechanically impossible above about 150kg. Those conclusions were largely based on simply scaling up modern kangaroos, which scientists from The University of Manchester, in collaboration with the University of Bristol and the University of Melbourne suspected might be misleading.

Now, by combining measurements from living kangaroos with direct evidence from fossil bones, the new study, published today in the journal finds that giant kangaroos may have been capable of hopping.

Lead researcher Megan Jones, Postgraduate Researcher at The University of Manchester, said: “Previous estimates were based on simply scaling up modern kangaroos, which may mean we miss crucial anatomical differences. Our findings show that these animals weren’t just larger versions of today’s kangaroos, they were built differently, in ways that helped them manage their enormous size.”

The team examined two potential limiting factors for hopping - the strength of the foot bones and the ability of the ankle to anchor the powerful tendons that drive a hop.

Their analysis show that the giant kangaroos had shorter, thicker foot bones capable of withstanding landing forces and their heel bones were broad enough to support much thicker ankle tendons than those of modern kangaroos.

However, these giants probably did not bounce across the landscape like today’s red kangaroos.

“Thicker tendons are safer, but they store less elastic energy,” explained s, Royal Society Research Fellow at The University of Bristol. “This likely made giant kangaroos slower and less efficient hoppers, better suited to short bursts of movement rather than long-distance travel. But hopping does not have to be extremely energy efficient to be useful, these animals probably used their hopping ability to cross rough ground quickly or to escape danger.”

The fossil analysis also revealed a range of locomotion strategies among the extinct species. Some giant kangaroos may have mixed hopping with other forms of movement, including walking upright on two legs, or moving on all fours, suggesting that hopping was just one part of a broader “movement repertoire”.

But the diversity of prehistoric Australia extends beyond just movement.

, Senior Lecturer in Evolution, Infection and Genomics at The University of Manchester, said “Our findings contribute to the notion that kangaroos had a broader ecological diversity in prehistoric Australia than we find today, with some large species grazers like modern kangaroos while others were browsers – an ecological niche not seen in today’s large kangaroos.”&�Բ�����;

The findings provide the most comprehensive assessment to date of the mechanical feasibility of hopping in giant extinct kangaroos.

Scientists have long known that inherited neurodegenerative disorders, including Alzheimer’s, Parkinson’s or motor neurone disease, can be traced back to genetic mutations. However, how they cause the diseases remains unanswered.

In today’s issue of the journal Current Biology Professor Andreas Prokop revealed that so-called ‘motor proteins’ can provide key answers in this quest.

The research by the Prokop group focusses on nerve fibres, also called axons. Axons are the delicate biological cables that send messages between the brain and body to control our movements and behaviour. Intriguingly, axons need to survive and stay functional for our entire lifetime!

To survive long-term, axons harbour complex cellular machinery. This machinery crucially depends on the transport of materials from the distant nerve cell bodies which is performed by motor proteins running along thin fibres called microtubules.

If mutations in motor protein genes abolish their ability to transport cargo, this causes axonal decay, and many inherited neurodegenerative diseases can be traced back to such mutations. However, another class of mutations also linking to neurodegeneration, causes motor protein hyperactivation, meaning that motor proteins are constantly active, unable to pause.

“So far, it has been difficult to explain why both disabling and hyperactivating mutations can cause very similar forms of neurodegeneration.” said Professor Prokop.

“To find answers, we use fruit flies, where research is fast and cost-effective and where many of the relevant human genes have close equivalents and perform similar functions in nerve cells. Capitalising on these advantages, we could show that disabling as well as hyperactivating mutations cause a very similar pathology in axons: straight microtubule bundles decay into areas of disorganised microtubule curling, similar to dry versus boiled spaghetti.”

Further investigations revealed that hyperactivating and disabling mutations work through two different mechanisms that eventually converge to induce this curling:

Even under normal conditions, cargo transport along microtubules generates damage, like cars cause potholes – and this requires maintenance mechanisms to repair and replace microtubules. The balance between damage and repair is disturbed if motor proteins are hyperactivated or if maintenance machinery fails - both leading to microtubule curling as a sign of axon decay.

Prokop said: “In this scenario, disabling mutations could be assumed to cause less curling because there is less damaging traffic. However, less traffic depletes supply to the axonal machinery, and this triggers a condition referred to as oxidative stress. We could show that oxidative stress affects microtubule maintenance and leads therefore to the same kind of microtubule curling as observed upon motor hyperactivation.”

“These findings suggest a circular relationship which we called the “dependency cycle of axon homeostasis”, proposing that axon maintenance requires a microtubule- and motor protein-based machinery of transport which, itself, is dependent on this transport.”

Any gene mutations affecting axonal machinery in ways that cause oxidative stress, or that disturb the balance between microtubule damage or repair, can break this cycle. This can explain a long-standing conundrum in the field: why almost any class of neurodegenerative disease can be caused by mutations in a wide range of genes linking to very different cellular functions.

He added: “Parallel work by my group strongly supports the dependency cycle model. Importantly, since the fundamental genetic makeup of fruit flies and humans is surprisingly similar, it is very likely that our findings are replicated in humans – and there are good indications already.”

New Windows on Fundamental Physics: from tabletop devices to large-scale detectors (19–23 January 2026) unites experts from particle theory, particle physics, nuclear physics, atomic and molecular physics and selected areas of astrophysics. The five-day meeting is designed to accelerate collaboration, stimulate new research ideas and create new partnerships within the global quantum science and engineering research community. 

, Research Associate in Particle Theory, the Quantum Technologies for Fundamental Physics (QTFP) lead, and the workshop chair explains: “By bringing together world experts across theory and experiment, we are creating space for the next generation of joint projects. In keeping the workshop intentionally small and focused, we aim to foster the kind of deep discussions that aren't always possible at larger, more formal conferences.”&�Բ�����;

The programme comprises: 

• a one-day UK Astroparticle Phenomenology (UK-APP) workshop featuring contributed talks, and
• a four-day specialist workshop with invited and contributed talks.   

The workshop will have a particular emphasis on tabletop detectors and quantum technologies for fundamental physics (QTFP), covering topics including precision metrology and quantum sensing, cold atoms and molecules, quantum analogues, atom interferometry, fifth-force tests, axion/WIMP dark matter and dark energy, neutrinos, gravitational-wave detectors, high-frequency gravitational waves and emerging tabletop detection techniques. 

, a UKRI Future Leaders Fellow and The University 91ֱ�� representative to the Terrestrial Very-Long-Baseline Atom Interferometry collaboration, and workshop co-organiser, adds: “There is a near-term opportunity to build partnerships that will shape the future of this exciting multi-disciplinary area of research and capture support through the next wave of funding programmes.”&�Բ�����;, Head of the Photon Science Institute and Nuclear Physics Group continues: “Our aim is to enable researchers to share emerging work, explore new directions and identify opportunities for joint initiatives.”&�Բ�����;

Professor Sarah Sharples, Vice-President and Dean of the Faculty of Science and Engineering underscores: “This workshop is a reminder of what can be achieved when we bring people together with a shared curiosity. By creating space for open exchange and collaboration, 91ֱ�� is helping to connect expertise from across the world in ways that move this field forward. It’s a collective endeavour; one that grows stronger when we work across boundaries and advance knowledge together.”&�Բ�����;

The event reflects wider momentum in quantum science at 91ֱ��, supported by a series of strategic hires, including multiple new Chairs in Quantum Science. These appointments bring new researchers into an environment defined by growing interdisciplinary activity, strong international partnerships – from the University of Washington to Nanoco – and access to world-leading capabilities such as the P-NAME instrument and the facilities at the Henry Royce Institute.

Workshop: New Windows on Fundamental Physics: from tabletop devices to large-scale detectors Dates: 19-23 January 2026 Location: The University of Manchester

The cloud of iron atoms, described for the first time in , just fits inside the inner layer of the elliptically shaped nebula - a colourful shell of gas thrown off by a star as it ends the nuclear fuel-burning phase of its life. It is familiar from many images including those obtained by the James Webb Space Telescope at infrared wavelength.

The bar’s length is roughly 500 times that of Pluto’s orbit around the Sun and, according to the team, which includes researchers from The University of Manchester, its mass of iron atoms is comparable to the mass of Mars.

The iron cloud was discovered in observations obtained using the Large Integral Field Unit (LIFU) mode of the - a new instrument installed on the Isaac Newton Group’s 4.2-metre William Herschel Telescope. 

The LIFU is a bundle of hundreds of optical fibres.  It has enabled the team of astronomers to obtain spectra (where light is separated into its constituent wavelengths) at every point across the entire face of the Ring Nebula, and at all optical wavelengths, for the first time. 

Lead author Dr Roger Wesson, based jointly at University College London and Cardiff University, said: “Even though the Ring Nebula has been studied using many different telescopes and instruments, WEAVE has allowed us to observe it in a new way, providing so much more detail than before. By obtaining a spectrum continuously across the whole nebula, we can create images of the nebula at any wavelength and determine its chemical composition at any position.

“When we processed the data and scrolled through the images, one thing popped out as clear as anything – this previously unknown ‘bar’ of ionized iron atoms, in the middle of the familiar and iconic ring.”

Co-author , Professor of Astrophysics at The University of Manchester, added: “We selected the Ring Nebula as an early target because it is bright, well studied and ideal for testing the instrument’s capabilities. However, when the data were analysed, we noticed something entirely unexpected - a bar of highly ionised iron that had gone unnoticed in decades of previous observations. Discoveries like this show how many surprises there still are to be found in even the most familiar objects in the night sky.”

How the iron bar formed is currently a mystery, the authors say.  They will need further, more detailed observations to unravel what is going on. There are two potential scenarios: the iron bar may reveal something new about how the ejection of the nebula by the parent star progressed, or the iron might be an arc of plasma resulting from the vaporisation of particles of iron dust embedded in the Ring Nebula. 

Co-author Professor Janet Drew, also based at UCL, advises caution: “We definitely need to know more – particularly whether any other chemical elements co-exist with the newly-detected iron, as this would probably tell us the right class of model to pursue.  Right now, we are missing this important information.”

The team are working on a follow-up study, and plan to obtain data using WEAVE’s LIFU at higher spectral resolution to better understand how the bar might have formed.

WEAVE is carrying out eight surveys over the next five years, targeting everything from nearby white dwarfs to very distant galaxies. The Stellar, Circumstellar and Interstellar Physics strand of the WEAVE survey, led by Professor Drew, is observing many more ionized nebulae across the northern Milky Way.

“It would be very surprising if the iron bar in the Ring is unique,” explains Dr. Wesson. “So hopefully, as we observe and analyse more nebulae created in the same way, we will discover more examples of this phenomenon, which will help us to understand where the iron comes from.”

Professor Scott Trager, WEAVE Project Scientist based at the University of Groningen, added: “The discovery of this fascinating, previously unknown structure in a night-sky jewel, beloved by sky watchers across the Northern Hemisphere, demonstrates the amazing capabilities of WEAVE.  We look forward to many more discoveries from this new instrument.”

Researchers at The University of Manchester, working with the UK’s National Physical Laboratory and 15 international partners, have developed a robust protocol using transmission electron microscopy (TEM). The results, published in , will underpin a new ISO technical specification for graphene.

“To incorporate graphene and other 2D materials into industrial applications, from light-weight vehicles to sports equipment, touch screens, sensors and electronics, you need to know you’re working with the right material. This study sets a global benchmark that industry can trust,” said , who worked on the research during his PhD.

“Electron diffraction has long been used to distinguish monolayer from few‑layer graphene, but it’s often applied without a full treatment of uncertainties. By collaborating across 15 leading labs. including the original pioneers, we’ve mapped the pitfalls and shown how to get reliable results” added Dr Evan Tillotson.

“We’ve designed this protocol so it works in real labs, not just in specialist centres. And for organisations without TEM capability, we can provide measurements commercially through our partnership with the ,” said , Professor of Materials.

The findings are used directly within the  international standard, currently in press and expected to be published in 2026. “This work builds on the NPL Good Practice Guide 145 'Characterisation of the Structure of Graphene’ developed in partnership with the University of Manchester, and one of NPL's most downloaded guides.", notes , Principal Scientist of the Surface Technology Group and Advanced Materials Strategy Lead at NPL.

Professor Sarah Haigh is available for interview on request.

The appointment, which began on 1 January 2026, follows a year-long sabbatical spent at Monash University and the European Synchrotron Radiation Facility in Grenoble, and reflects a shared ambition to deepen collaboration between the UK and Australia in advanced materials research and manufacturing.

In line with this, Professor Withers will also take up responsibility for identification and establishment of Strategic Research Partnerships at the .

Reflecting on the new role, said: “During my time in Melbourne, I saw enormous potential for deeper collaboration between UK and Australian universities, particularly in Advanced Materials Manufacturing. Working across these two world-class institutions, and more broadly between our two countries, offers significant opportunities for innovation and impact. Furthermore, this three-way appointment also allows me to build on the strong national platform that the Royce has established over its first decade, by helping to develop and sustain robust international academic and industrial partnerships.”

The University of Manchester is home to more than 700 materials experts whose research is revolutionising industries through the development of advanced materials that unlock new levels of performance, efficiency and sustainability. Supported by the University’s £885 million investment in its campus over the past decade, researchers are at the forefront of materials innovation, delivering game-changing solutions across sectors from healthcare to manufacturing, tackling global challenges and reinforcing the UK’s reputation as a technology ‘superpower’.

Over the next five years, Professor Withers’ joint appointment will support collaborative research programmes between 91ֱ�� and Monash, enable greater researcher and student exchange, and strengthen engagement with industry partners across both countries, particularly in the area of advanced materials manufacturing.

, Vice Dean and Head of School of Natural Sciences at The University of Manchester said: “This is an excellent opportunity to build on our existing links with Monash and the exciting future that this collaboration will deliver.  Phil’s joint appointment will enable us to create multiple strands of activity across a wide range of materials science and engineering and beyond.”

Professor Mahmoud Mostafavi, Head of Department of Mechanical and Aerospace Engineering at Monash University, added: “Regius Professor Withers, FRS is a world-renowned materials scientist and engineer and a leading international figure in key subjects. We are extremely delighted that he will be joining Monash at this critical time for Australia. In addition to his extraordinary research leadership, Professor Withers will be acting as a bridge between materials research in Australia and UK, Europe, and the rest of world, particularly through his affiliation with the Henry .”&�Բ�����;

Professor Withers is the inaugural Regius Professor of Materials and his research focuses on understanding how engineering materials perform, particularly in demanding environments, and on developing new materials with improved durability and performance. He is internationally recognised for his pioneering use of X-ray imaging techniques to create three-dimensional images of materials, revealing their microstructure and identifying defects or damage in engineering components.

In recognition of this work, the Henry Moseley X-ray Imaging Facility (HMXIF), established by Professor Withers, was awarded the Queen’s Anniversary Prize in 2014. The HIMXIF, has since grown into one of the most extensive suites of 3D X-ray imaging facilities in the world and now host the.

Professor Withers is a Fellow of both the Royal Society, the Royal Academy of Engineering and Academia Europea as well as a foreign member of the Chinese Academy of Engineering and the Indian National Science Academy. In 2012, he became the inaugural Director of the BP International Centre for Advanced Materials, which focuses on understanding and developing materials for the energy sector. As Chief Scientist at the Henry Royce Institute, he leads the development of the Institute’s research strategy - all expertise he will bring to his joint appointment with Monash University.

The project, led by Professor Yasser Mahmoudi Larimi from The University of Manchester, has been awarded a £3 million EPSRC Critical Mass Programme Grant. It brings together expertise from industry and academia across the UK, including The University of Manchester, the University of Birmingham, the University of Liverpool, Cranfield University and Imperial College London.

As the UK increases its use of renewable energy, one of the biggest challenges is how to store excess electricity generated on windy or sunny days and make it available when demand rises, or when the weather changes and turns dark, for example. GPStore aims to deliver a first-of-its-kind approach to storing clean energy for hours, weeks or months - something existing storage options cannot achieve at scale.

By 2050, the UK is expected to need up to 100 terawatt-hours of long-duration energy storage to ensure a stable, affordable and low-carbon energy system. While today’s technologies, such as pumped hydro, compressed air and flow batteries, offer useful short- to medium-duration storage, they often face geographical and environmental constraints, high costs, or complex engineering, making them difficult to scale.

The novel GPStore technology takes a completely different approach. It converts surplus renewable electricity into high-temperature heat storing in solid particles, in aboveground insulated tanks. When energy is needed, the stored thermal energy is converted back to electricity. GPStore could help manage energy demand not only day-to-day, but also between summer and winter, which is essential for achieving a fully renewable, climate-resilient energy grid.

The project brings together 13 academics across five UK universities and 16 industry and policy partners, including Baker Hughes, EDF Energy, UK Power Networks, Fraser-Nash Consultancy and 91ֱ�� City Council.

The initiative, known as the Resource for AI Science in Europe (RAISE), brings together computing power, data, expertise and funding to support researchers in applying AI to scientific discovery across all disciplines.

Following an announcement at the AI in Science Summit in Copenhagen, the SCIANCE (AI in Science) consortium, which includes researchers at The University of Manchester, has been invited to enter into a grant agreement to support the development and pilot phase of RAISE under Horizon Europe.

SCIANCE will coordinate AI-enabled science across Europe through a bottom-up, community-driven approach, bringing together top research organisations and major research facilities from across Europe, focusing on five key areas of science: physics and astronomy, materials science, life sciences, earth sciences, and social sciences and humanities.

The project will, among other things, deliver:

• A Strategic Research and Innovation Agenda (SRIA) for AI in Science
• An implementation roadmap for infrastructure upgrades
• The RAISE Secretariat for AI in science, to support long-term collaboration, capacity building, and alignment with European policy objectives.

The University of Manchester brings an interdisciplinary team of researchers, including , who will act at the Scientific Coordinator for Astronomy and Astrophysics, and , also from , supported by from the 91ֱ�� . 

RAISE is a flagship initiative under the European Strategy for AI in Science and aims to position Europe as a global leader in AI-enabled research by supporting scientists to develop and apply AI for transformative discoveries.

Jonas L’Haridon, Project Coordinator, ESF, said: “SCIANCE represents a unique opportunity to coordinate AI-enabled science across Europe - connecting research communities, infrastructures and AI expertise in a way that truly reflects scientific priorities.”

The GPIW is an international initiative that recognises pioneering contributions to water desalination and celebrates innovators driving progress towards sustainable global water solutions. Winning this award places Hollowgraf Ltd among the most influential emerging innovators in the global water sector. 

Hollowgraf originates from the graphene membrane research group led by , internationally recognised for its work on graphene-based membranes for separation and filtration. Building on this foundation, the team has filed a patent for an innovative desalination and value-recovery process powered by atmospheric CO₂ or flue gas. To accelerate real-world deployment, the team established Hollowgraf Ltd to commercialise the technology. 

With water scarcity affecting billions worldwide, Hollowgraf’s technology offers a radical new approach: turning seawater into drinking water using carbon dioxide and advanced graphene membranes. This innovation could transform desalination into a near-zero-waste process.  

Hollowgraf stood out among 2,570 entries from 119 countries, securing $50,000 in prize money and $250,000 in prototype and piloting support, fuelling the next stage of development and scale-up. 

“This recognition is a huge step toward turning cutting-edge graphene research into real-world solutions for water scarcity. With this support, we can move from the lab to large-scale pilot projects in partnership with the Saudi Water Authority,” said , Research Fellow at the National Graphene Institute and CEO of Hollowgraf Ltd. 

Prof. Rahul Raveendran Nair, Professor and Royal Academy of Engineering Research Chair at The University of Manchester and CTO of Hollowgraf Ltd, said: 

“This award highlights our commitment to turning world-class research into solutions for global challenges. Hollowgraf’s breakthrough could redefine sustainable desalination, and we’re proud to see 91ֱ�� innovation recognised worldwide.”&�Բ�����;

The patent-pending process, developed at The University of Manchester, uses graphene membranes and carbon dioxide to produce clean water and valuable by-products, all at ambient pressure thus making it more sustainable and cost-effective than traditional methods. 

This achievement reinforces The University of Manchester’s position as a global leader in graphene innovation and sustainability, making a tangible impact on one of the world’s most pressing challenges. 

The is a world-leading graphene and 2D material centre, focussed on fundamental research. Based at The University of Manchester, where graphene was first isolated in 2004 by Professors Sir Andre Geim and Sir Kostya Novoselov, it is home to leaders in their field – a community of research specialists delivering transformative discovery. This expertise is matched by £13m leading-edge facilities, such as the largest class 5 and 6 cleanrooms in global academia, which gives the NGI the capabilities to advance underpinning industrial applications in key areas including: composites, functional membranes, energy, membranes for green hydrogen, ultra-high vacuum 2D materials, nanomedicine, 2D based printed electronics, and characterisation.

Engineers and geologists in the “DUST” group at the University have developed a synthetic test dust supported by an EPSRC IAA Proof of Concept grant, led by Dr Merren Jones and , that accurately replicates the fine, talcum-powder-like particles commonly found in desert regions - materials known for causing accelerated wear on some aeroengine components.

This recreated dust has become an important element of Rolls-Royce’s extensive testing programme in Derby, where the company is working to improve the durability of engines used by airlines.

Sand ingested during take-off and climb can penetrate the hottest parts of an engine, corrode components, and block coolant holes. While not a safety issue, the damage reduces efficiency, increases the maintenance burden, and shortens component life.

Using the University of Manchester’s synthetic dust, Rolls-Royce has been able to replicate harsh Middle Eastern conditions inside its Testbed 80 facility in Sinfin.

of the University’s DUST Research Group, said: “Standard test dusts do not contain the same chemical composition as the dust we see in the air of these increasingly busy airport hubs, therefore would not stress the engine in the same way. A bespoke recipe was needed to reproduce the molten glassy deposits that cause the damage in the hottest parts of the jet engine. Combining the expertise of geologists, who are familiar with the minerals of these regions and how they break down under high temperature, with engineers who can simulate the conditions inside a jet engine, has been pivotal in developing this bespoke test dust.”

This realistic testing allowed engineers to trial new coatings that better withstand heat and corrosion, and to redesign coolant holes so they are less prone to blockage.

According to Pat Hilton, Rolls-Royce’s Test Facilities Manager, the University’s contribution has helped increase the understanding of how dust behaves inside high-temperature turbines. Engine changes have been tested with the synthetic raw material and modified engines have returned to service, showing  a 60% increase in time between overhauls.

The DUST group (Drs Jones, , and )  continues to support this effort through InnovateUK-funded projects focusing on on-wing component inspection and digital tool development for virtual sand and dust tests.

The work forms part of a £1 billion durability programme aimed at doubling the lifespan of engines such as the Trent XWB-97 by 2028. 91ֱ��’s breakthrough dust replica is an important tool to achieve this goal, helping Rolls-Royce strengthen performance across its Middle Eastern fleet.

Published today in , the images reveal a series of delicate, ring-like structures that record decades of violent outbursts during the star’s early life.

The international study, which included astronomers at The University of Manchester, used the Atacama Large Millimeter/submillimeter Array (ALMA), one of the world’s most advanced astronomical facilities.

The team focused on a fast-moving jet emerging from SVS 13, a binary system around 1,000 light-years from Earth, capturing high-resolution images that show hundreds of nested molecular rings. Each group of rings trace the aftermath of an energetic burst during the star’s infancy.

The findings provide the first direct confirmation of a three decade old model of these jets, allowing the reconstruction of the chronological record of how forming stars feed on, and then explosively expel, surrounding material.

is a co-author on the paper and Principal Investigator of the UK ALMA Regional Centre Node, which supports UK astronomers in their use of the ALMA observatory.

He said: “ALMA has provided a level of precision we’ve never been able to achieve before. These images give us a completely new way of reading a young star’s history.
Each group of rings is effectively a time-stamp of a past eruption. It gives us an important new insight into how young stars grow and how their developing planetary systems are shaped.”

Stars like the Sun form deep within dense clouds of gas and dust. In their earliest stages, they undergo energetic outbursts that heat and disturb the material around them. At the same time, they launch rapid, tightly collimated jets of gas that play a crucial role in regulating how the star accumulates matter and how its surrounding disc – where future planets eventually form – evolves.

The team identified more than 400 individual rings in the jet from SVS 13, showing how its shape and speed change over time as it punches through its environment. Using this data, the researchers reconstructed the jet’s 3D structure in unprecedented detail – a technique they describe as “cosmic tomography”.

They found that the youngest ring matches a bright outburst observed from the SVS 13 system in the early 1990s. This is the first time astronomers have been able to directly connect a specific burst of activity in a forming star with a change in the speed of its jet.

The project involved researchers from 16 institutions across eight countries and was led by the Institute of Astrophysics of Andalusia (IAA-CSIC) in Spain. The new ALMA observations form part of a long-running project to understand how stars and planets form, building on earlier work from the US National Science Foundation’s Very Large Array (VLA), which first revealed the jets from SVS 13.

The study, published in the journal , is based on interviews with 23 housing and construction specialists. It reveals widespread concern that while heating in homes has long been a priority, cooling in homes is largely overlooked, despite climate change driving more frequent heatwaves.

The researchers warn that without urgent action, residents could face increasing energy bills and worsening health risks, increasing pressure on NHS and emergency services during extreme heat.

The study highlights gaps in policy and long-term funding making it difficult for the sector to deliver energy-efficient, climate-resilient homes and short-term schemes, like the Warm Homes Grant, may not provide long-term solutions.

It also highlights a skills gap and a lack of guidance on climate-resilient home design, particularly for cooling solutions.

The report calls for urgent action to:

• Establish a national climate-resilience strategy for homes, aligning housing policy with UK climate commitments
• Provide long-term, stable funding for social housing retrofits
• Prioritise cooling, ventilation and overheating prevention alongside heating efficiency
• Strengthen training and skills programmes for low-carbon, climate-resilient construction
• Ensure equitable outcomes for low-income households as energy systems transition

Lead researcher , a PhD researcher at The University of Manchester's Tyndall 91ֱ��, said: “The UK is not moving fast enough to protect residents from the impacts of climate change. Our research makes clear that we urgently need a comprehensive climate-resilience framework - one that brings together strategy, regulation, construction practice and smart energy-demand management.

“Thermal comfort is a basic human need and our social homes must be safe, affordable and resilient. Overheating is already a risk, particularly for vulnerable residents, yet cooling is barely discussed in policy or practice. From our interviews, we can see that the construction sector is ready to act, but it needs clear direction, long-term commitment and a fair policy framework from the government.”

The UK is committed to building over 1.5 million new homes while achieving net-zero carbon emissions by 2050. The researchers stress that without urgent action, the UK will fall further behind these climate targets.

While the introduction of Building Regulations Part O in 2022 marked progress, the researchers say it does not go far enough to counter the long-term temperature rise projected for the UK.

Claire Brown added: “Housing must be treated as critical infrastructure, just like schools and hospitals, if we are to meet carbon budgets while delivering more than 1.5 million new homes. Without significant systemic change, we risk locking in higher emissions, higher costs and poorer outcomes for the people who rely on social housing most.”

In a study published today in , the team demonstrate a completely new way of probing the tiny “ticking” of the thorium-229 nucleus without needing a specialised transparent crystal – a breakthrough that could underpin a new class of timekeeping so precise it could transform navigation, communications, earthquake and volcano prediction, and deep-space exploration.

The advance builds on a landmark achievement , when the team succeeded  in using a laser to excite the nucleus of thorium-229 inside a transparent crystal - a feat the team has been working on for the past 15 years.

Now, researchers have achieved the same results using a tiny fraction of the material and with a method so simple and inexpensive that it opens the door to real-world nuclear clock technology.

“Previously, the transparent crystals needed to hold thorium-229 were technically demanding and costly to produce, which placed real limits on any practical application,” explained , co-author of the research and Lecturer in Computational and Theoretical Chemistry at The University of Manchester. “This new approach is a major step forward for the future of nuclear clocks and leaves little doubt that such a device is feasible and potentially much closer than anyone expected.”

In the new study, the team instead excited the thorium nucleus inside a microscopic thin film of thorium oxide, made by electroplating a minute amount of thorium onto a stainless-steel disc – a process similar to gold-plating jewellery and a radical simplification of their previous method.

The thorium nuclei absorb energy from a laser and then, after a few microseconds, transfer that energy to nearby electrons so it can be measured directly as an electric current. This method, known as conversion electron Mössbauer spectroscopy, has been in use for years, but normally requires high-energy gamma rays at special facilities. This is the first time it has  been demonstrated with a laser in an ordinary lab.

Crucially, it shows that thorium-229 can be studied inside far more common materials than previously thought, removing one of the biggest obstacles to building practical nuclear clocks.

The technique also offers new insight into how thorium-229 behaves and decays, which could one day inform new types of nuclear materials and future energy research.

“We had always assumed that in order to excite and then observe the nuclear transition the thorium needed to be embedded in a material that was transparent to the light used to excite the nucleus. In this work, we realized that is simply not true,” said UCLA physicist Eric Hudson., who led the research. “We can still force enough light into these opaque materials to excite nuclei near the surface and then, instead of emitting photons like they do in transparent materials like the crystals, they emit electrons which can be detected simply by monitoring an electrical current – which is just about the easiest thing you can do in the lab.”

Like atomic clocks, nuclear clocks rely on the natural “ticking” of single atoms. But in atomic clocks that process involves electrons, while nuclear clocks use oscillations within the nucleus itself. This makes them far less sensitive to external disturbances, giving them the potential to be orders of magnitude more accurate.

Nuclear clocks could even be used to predict earthquakes and volcanic eruptions. Because of Einstein’s theory of general relativity, nuclear clocks should be sensitive to small changes in the Earth’s gravity due to the movement of magma and rock deep underground. By placing nuclear clocks all over earthquake zones, like Japan, Indonesia, or Pakistan, we could watch what’s going on beneath our feet in real time and predict tectonic events before they happen.

Dr Morgan added: “In the long term, this technology could revolutionise our ability to prepare for natural disasters. It’s incredibly exciting to think that thorium clocks can do things we previously thought were impossible, as well as improving everything we currently use atomic clocks for.”

The research was funded by the National Science Foundation, and also included physicists from the University of Nevada Reno, Los Alamos National Laboratory, Ziegler Analytics, Johannes Gutenberg-Universität at Mainz, and Ludwig-Maximilians-Universität München.

Thanks to a €2.25M Consolidator Grant from the European Research Council (ERC), UnifySky - a five-year project led by Dr Phil Bull - will combine decades of existing radio observations with new data from a custom-built horn-antenna – named RHINO - to tackle one of cosmology’s biggest challenges.

The “radio sky” refers to the radio waves emitted by objects across the Universe, including pulsars, quasars, and clouds of hydrogen gas. Although invisible to the human eye, these signals carry vital clues about the Universe’s earliest moments, such as how the first stars and galaxies formed. Mapping the radio sky allows astronomers to uncover hidden structures and processes that cannot be seen with traditional optical telescopes. However, progress has been held back by sky maps that are incomplete, inconsistent, or affected by instrumental errors.

“Existing sky maps can be wrong by more than 10%, yet we need errors below 1%,” explained Dr Bull, Reader in Cosmology at the Jodrell Bank Centre for Astrophysics, University of Manchester. “These inaccuracies arise from old, inconsistent data stitched together from many different telescopes. Without improved models, the faint signals from the first stars and galaxies are lost beneath the much stronger radio emission from our own Galaxy.”

To achieve this, the project will combine decades of existing observations with new, precisely calibrated measurements from RHINO. Using advanced statistical techniques implemented in Dr Bull’s world-leading software, UnifySky will untangle overlapping signals and correct for errors from previous instruments, producing the first fully consistent model of the radio sky.

A key target is the extremely faint 21cm signal emitted by hydrogen in the early Universe, which carries key information about when the first stars and galaxies formed. The improved models will transform the scientific output of major experiments such as the ), and the which are seeking to observe the signal.

The project will also revisit two puzzling results reported by the instrument and experiment, which both detected unusual radio signals that some researchers have suggested might hint at new physics.  It is not yet clear whether these signals are real or the result of errors in making these tricky measurements.

The UnifySky project will focus on three main areas of work:

1.      Building a high-precision statistical model of the radio sky
By developing an advanced statistical model that combines past and current radio observations, the project will produce a single, consistent map of the sky. This model will correct long-standing errors, account for uncertainties, and provide a flexible tool for calibrating telescopes and studying the faint signals from the early Universe.

2.      Observing the sky with a novel horn antenna telescope
By building a precisely calibrated horn antenna called the project will reobserve the unusual signal seen by the EDGES experiment and provide a reliable reference for other measurements. The antenna will be the size of a semi-detached house, and will be built at the Jodrell Bank Observatory, a stone’s throw away from the historic Lovell telescope.

3.      Unlocking new physics from the radio sky
By combining the new, high-precision sky model with RHINO’s calibrated measurements, the project will re-analyse data from leading radio telescopes to study the early Universe. This will improve measurements of the 21cm signal from the first stars and galaxies, map the radio emission from our Galaxy, and separate different sources of cosmic radio waves. The results will give new insights into the formation of early structures and the effects of dark energy.

The work builds on Jodrell Bank’s long-standing global reputation in radio astronomy, together with Dr Phil Bull’s world-leading expertise in theoretical and observational cosmology, ensuring 91ֱ�� is uniquely equipped to deliver the UnifySky project.

An international collaboration of scientists, including from The University of Manchester, working on the experiment at the U.S. Department of Energy’s Fermi National Accelerator Laboratory announced that they have found no evidence for a fourth type of neutrino, known as a sterile neutrino.

For decades, physics experiments have observed neutrinos - sub-atomic particles that are all around us - behaving in a way that doesn’t fit . One of the most promising explanations was the existence of a sterile neutrino, named because they are predicted not to interact with matter at all, whereas other neutrinos can. This means they could pass through the Universe almost undetected.

Using a highly sensitive detector called MicroBooNE, sitting on two different neutrino beams, the researchers observed how thousands of neutrinos behaved over several years. If the fourth neutrinos existed, it would have left a clear fingerprint. The result, published today in the journal , shows there was no evidence and rules out a single sterile neutrino explanation with 95% certainty.

Professor of Particle Physics at The University of Manchester and co-spokesperson for MicroBooNE, said: “Any time you rule out one place where physics beyond the Standard Model could be, that makes you look in other places. This is a result that is going to really spur a creative push in the neutrino physics community to come up with yet more exciting ways of looking for new physics. Sometimes, science is just as much about what you don’t find as what you do."

The University of Manchester played a leading role in the breakthrough. Dr Elena Gramellini was the driving force behind the experiment’s physics programme using the NuMI beam - a crucial part of the analysis behind this result. Professor Roxanne Guenette was one of the originators of MicroBooNE’s short-baseline oscillation programme, helping to shape the strategy used to investigate the sterile-neutrino question. The new paper builds directly on that foundational work.

Neutrinos come in three known types, or flavours: muon, electron and tau. They can change from one type to another as they travel. But this flavour-flipping cannot fully be explained by the current Standard Model.

Some earlier experiments - -  also made observations suggesting that muon neutrinos were oscillating into electron neutrinos over shorter distances than should be possible.

“They saw flavour change on a length scale that is just not consistent with there only being three neutrinos,” explained , “And the most popular explanation over the past 30 years to explain the anomaly is that there’s a sterile neutrino.”

The experiment collected data from 2015 to 2021, observing neutrinos from Fermilab’s Booster Neutrino Beam and the NuMI beam. MicroBooNE is the first experiment that has done a sterile neutrino search with one detector and two beams simultaneously. This reduces the uncertainties in MicroBooNE’s result, making it possible to exclude nearly the entire favoured region in which a single sterile neutrino could be hiding. 

Although this result rules out one explanation for anomalies seen in neutrino behaviour, the mystery itself remains. Scientists are now analysing the remaining MicroBooNE data and other experiments in the Short-Baseline Neutrino Program are also on the case.

In addition to the search for new physics, the MicroBooNE collaboration is providing insight into how neutrinos interact in liquid argon, an important metric that will benefit other liquid-argon time projection chamber experiments such as the .

Matthew Toups, Fermilab senior scientist and co-spokesperson for MicroBooNE, said: “It’s really exciting to be doing both cutting-edge science that has a major impact on our field as well as developing novel techniques that will support and enable future scientific measurements.”

On the western flanks of Mount Kenya lies the Laikipia plateau, an achingly beautiful landscape that is both a refuge for wildlife and a home to traditional Masai communities. Black rhinos, which were once nearly extinct, are now thriving on some of these conservation properties, thanks to the intense efforts to keep them safe.

The tells the story of the people and the challenges faced to in this volatile landscape. The cinematography and score beautifully captures the landscape, people, animals and pace of life, which is at times languorous and at times frantic.

The story unfolds from the perspective of two rangers. Ramson Kiluko is an experienced ranger who works with his team to watch, protect and understand the rhinos. The film gives us a glimpse into his family life, the camaraderie of the ranger team and the rich knowledge he has about the lives of individual rhinos and their landscape. Rita Kulamu is a young ranger learning about rhinos as her property prepares to welcome them. Their work takes place against a background of danger, posed by both people and animals.

Rhino focuses on the critical role rangers play in the conservation story of black rhinos, which is an inspiring change from the traditional wildlife documentary that suggests a wildness that exists without the need for human intervention or involvement. Once on the brink of extinction, it is precisely the intensive efforts made to protect rhinos by people like Kiluko and Kulamu that has seen .

The film loosely follows a narrative around the planned move of 21 rhinos from the and reserves in central Kenya, where they are too numerous, to – a 58,000 acre wildlife conservation area which has long been without rhinos.

On Lewa and Borana, the rhinos fight for space and territory, on Loisaba they have the opportunity to create a new breeding population. Moving rhinos between reserves is a core part of their conservation. Poaching pressures require rhinos to be fiercely guarded. In Kenya, where my team has carried out research to understand the factors that lead to successfully breeding , rangers are tasked with finding each rhino every day. Fences that keep rhinos in and people out mean that rhinos cannot move to avoid threats, avoid inbreeding, or to reestablish populations where they no longer are found.

Moving rhinos is far from easy. They can be aggressive and need to be handled with care. Rhinos are also not very resilient to being moved between properties. These moves often lead to rhinos dying from fighting, stress and .

The film shows how led to a delay of several years to try to maximise the success . This widespread and prolonged drought caused intense suffering of humans, livestock and wildlife. Conflicts over animals and land boiled over, leading to violence but also . These day-to-day challenges faced by conservationists are rarely touched on. Hopefully this film will help audiences understand that there are legions of passionate conservation professionals behind every success story.

However, there is much that the story doesn’t tell. My experience researching wildlife health and disease in this landscape has highlighted how critical it is to create solutions that benefit both nature and people. Laikipia is a complicated landscape, where land rights, land ownership and power inequalities create tensions, and even violence, .

This is a landscape where settlers, European farmers that immigrated, appropriated the best, most productive beautiful lands from . High-end conservation reserves manage landscapes that teem with wildlife but are often off limits to the people that once moved widely with their animals. Our conversations with local people suggest that they view rhino conservation as a Trojan horse, moved around to justify high fences, armed security and to restrict people’s movement.

Rhino portrays the situation in somewhat simplistic terms: the good rangers and the bad “bandits”. In reality, conservation sits at a much less clear cut interface between the haves and the have nots, between those with international and national support for protecting animals, and pastoralists, a traditional way of life where people move with their herds of animals across the land, who feel their rights and traditional lands have been taken from them and that the wild animals have more rights that they do.

Violence comes not just from evil, avaricious thieves, but sometimes from frustrated, desperate people who have to deal with too many animals on too little land. Rhino tells an interesting and valuable story, but true conservation success must also address inequality, disenfranchisement and the tensions that “parachute” and colonial conservation in local communities.

The report, commissioned by Marketing 91ֱ��, Visit England, and the Growth Company, is the first detailed analysis of direct tourism emissions for a city-region in England. The findings reveal that international flights and domestic car travel are the biggest sources of emissions, alongside smaller impacts such as accommodation, and attractions.

Led by Dr Chris Jones and , the research also makes recommendations for how the region can grow a low carbon visitor economy in the region, supporting Greater 91ֱ��’s ambition to become carbon neutral by 2038.

The framework will act as a guide for other destinations to conduct similar assessments and address common data limitations in the tourism sector.

a Research Associate based at the Tyndall Centre for Climate Change, said: “Tourism connects people with places and cultures, while supporting local economies and jobs. However, this value can’t come at the expense of our environment. In the climate crisis it is vital that the sector becomes sustainable in every sense of the word. Measuring tourism emissions is challenging, but it is important for identifying where change is most needed.

“By commissioning this research Marketing 91ֱ�� has taken an important and proactive step to decarbonise tourism. We hope that this work will not only support Greater 91ֱ�� to take action and reimagine what truly sustainable tourism looks like, but also inspire other destinations to do the same.”

Key findings of the report include:

• International travel dominates emissions: Although relatively low visitor numbers, long-haul flights from Asia, Oceania, and North America make a disproportionately large contribution to carbon impacts.
• Domestic car travel a major contributor: Trips by petrol and diesel vehicles account for the majority of domestic travel emissions, even on well-connected rail routes.
• Trip profiles matter: Analysis suggests the carbon footprint or a trip to Greater 91ֱ�� can range from under 10kg CO₂e for regional day-trippers to over 500kg CO₂e for long-haul visitors. Mostly because of transport options.
• Low-carbon infrastructure already in place: Most major attractions benefit from excellent public transport accessibility, increasing the opportunity for car-free tourism.

Recommended actions include:

• Promoting rail and ferry access from nearby European countries.
• Targeting tourism growth in markets accessible by low-carbon transport.
• Supporting accommodation providers and attractions to meet local energy efficiency targets.
• Encouraging car-free tourism through public transport integration and sustainable travel itineraries.

The research establishes benchmark targets aligned with Greater 91ֱ��'s commitment to reach carbon neutrality by 2038 and its aim to be in in the Global Destination Sustainability Index top 40, including phasing out petrol and diesel car visits and ensuring no net growth in aviation emissions until truly low-carbon alternatives become available at scale. It also supports Marketing 91ֱ��'s participation in the Glasgow Declaration on Climate Action in Tourism.

Victoria Braddock, Managing Director of Marketing 91ֱ��, said: “Tourism is a significant contributor to Greater 91ֱ��’s economy, but we cannot overlook its environmental impact. As a destination, Greater 91ֱ�� is passionate about driving forward low-carbon tourism, and this report, in collaboration with the Tyndall Centre, is helping us set a standard for other English cities to follow through . Having clear objectives will help us to make a positive impact and support our partners to become greener in the process; all of which will contribute to our region’s ambition to become carbon neutral by 2038 and keep our status as a leading sustainable UK destination.”

Most national strategies emphasise supply-side technological solutions such as electrification and renewable energy generation. But the research, published today in , finds that supporting demand-side solutions, such as social and behavioural changes to how people travel, work, heat their homes, and consume goods, could cut total UK energy demand by between 18% and 45% by 2050 compared to today.

These demand-focussed pathways would continue to maintain quality of life while costing around half as much as technology-led pathways.

The finding is the result of a unique collaboration between academics from The University of Manchester, University College London, University of Leeds, and University of Oxford and members of the public, which informed a published by the UK Government Office for Science in 2023.

The study uniquely placed policymakers at the centre of modelling four future scenario designs, guided by the experts. Together, they explored how different mixes of technology, lifestyle, and social change could shape the country’s energy system and costs:

• Atomised Society: Rapid tech growth drives high consumption, but it creates a divided society where the rich are protected and the poor face greater climate risks.
• Metropolitan Society: High growth and trusted AI enable efficient living, but this concentrates prosperity in cities, creating an urban-rural divide.
• Self-preservation Society: Low growth and outdated tech lead to a fragmented society, though some communities find comfort in the slower, traditional pace of life.
• Slow Lane Society: Despite low growth, strong community values and high trust promote repair, reuse, and major cuts in energy demand.

Analysis shows that all four futures deliver lower energy demand than today, but reductions vary. The Slow Lane Society achieves the biggest cut (around 45%), while Atomised Society delivers the smallest (around 18%). Energy system costs also vary: the most energy-intensive future could see costs rise 136% by 2050, while the lowest-demand scenario limits this to just 24% compared to today.

Crucially, higher-demand futures depend far more on large-scale carbon removal technologies, which are still unproven at scale, whereas lower-demand pathways could reduce the need for such measures by around 70%.

The researchers also held discussions with members of the public to explore how believable each scenario felt and what impacts people thought they might have on everyday life. Participants generally viewed Metropolitan Society and Self-Preservation Society as most realistic, while Atomised and Slow Lane Societies were seen as more aspirational. Interestingly, while policymakers described Slow Lane as somewhat restrictive, the public viewed it as hopeful and positive.

The team say their approach could help other countries design people-centred climate policies that balance technological innovation with social, demand-side change.

Previously, little was known about the drivers of post-infection symptoms typically associated with severe viral infections, such as breathlessness and fatigue, but the study sheds light on what exactly might underpin these long-term effects.

“Serious viral infections like influenza and Sars-CoV-2 can cause long-term breathlessness and fatigue, though until now, the biological context to this has puzzled scientists,” said co-author Prof Tracy Hussell from The University of Manchester:

The study, funded by Wellcome and published in the journal Mucosal Immunology, also explains how inflammation may lead to aging in the lungs. 

The researchers found that following severe viral infection, a critical structure in the lung remains damaged, even after the symptoms and virus have both cleared. 

The structure, known as the basement membrane, is a thin supportive layer of extracellular matrix that anchors and separates cells from underlying tissue 

The basement membrane forms a barrier to line airspaces, support cells, and regulate fluid and cell movement. 

For the study, the lungs of mice with influenza virus were analysed by proteomic mass spectrometry, to identify potential protein biomarkers compared to non-infected mice.

The study also used peptide location fingerprinting, a technique developed by Dr Eckersley’s lab, which can identify damage across protein structures. 

They found that basement membrane proteins had reduced abundance and harboured structural damage following recovery from infection. 

That suggests post-viral damage is long-term, and that the membrane does not repair appropriately. The damage appeared patchy when observed histologically and resulted in leaky lungs.

 As similar structural damage was also observed by the scientists in aged lungs of non-infected mice, they propose that long-term, age-related complications may be caused by repeated inflammation.

Dr Alex Eckersley, from the University of Manchester said: “We’re very excited about our findings which reveal a new angle on why some viral infections have a long-term impact on lung health.

“Our study suggests that similar processes occur both when your lungs are exposed to a serious viral infection, and when you age.

“This means repeated viral infection could cause some people’s lungs to age more quickly.”

In many cases, the resolution of inflammation is incomplete, and the lung is thought to accumulate damage as a result over time.

By identifying evidence for this process, the  researchers hope to have found a new area of interest in developing therapeutic targets for treating long-term post-viral symptoms.

He added: “By identifying these persistent basement membrane changes, we provide an entirely novel area to target with new medicines to treat complications arising from viral infection.

“By providing new therapeutic targets, and opportunities to broaden our understanding of how relevant biological structures might be being damaged or struggling to repair, we can better understand, research, and medicate post-viral symptoms.”

The discovery, published in the journal , provides the first biomolecular data linking several extinct Australian megafauna species to their living relatives.

Led by at The University of Manchester, an international team analysed 51 fossilised marsupial bones collected from caves and swamps across Tasmania – one of the last refuges of these giant animals. Using an innovative technique called zooarchaeology by mass spectrometry (ZooMS), or collagen fingerprinting, the team was able to analyse fossils more than 100,000 years old – far beyond the age limit for traditional DNA analysis.

Dr Buckley said: “Until now, we’ve struggled to determine exactly how many of these extinct species were related because Australia’s hot climate destroys DNA over time. However, collagen proteins survive in much older and even extremely fragmented bones, allowing us to identify species and reconstruct the evolutionary relationships between extinct and living marsupials that could not be achieved through traditional methods.”

The most surprising discovery was that despite being wildly different animals, the koala and the marsupial lion - one of the largest meat-eating mammals ever to roam Australia - shared a common ancestor around 25-35 million years ago. This places the two animals much closer previously thought.

The research also provides new biomolecular data for two other extinct species – Zygomaturus trilobus and Palorchestes azael. Comparisons of their ancient collagen sequences confirmed that both belonged to the broader wombat–koala group, known as Vombatiformes.

The findings could help solve one of Australia’s biggest prehistoric mysteries surrounding the extinction of the continent’s giant animals.

During the Late Pleistocene, Australia lost nearly 90% of its giant land animals in one of the greatest extinction events in Earth’s history. Scientists are still debating whether the cause was climate change, human hunting, or a combination of both.

Because ZooMS can identify even tiny bone fragments and reveal their species, it could help scientists refine the timeline of when Australia’s megafauna disappeared and how long they overlapped with humans.

Dr Buckley added: “ZooMS also allows thousands of fossil specimens to be analysed quickly, so it could be a game-changer for the study of extinct species. We can now identify more fossils, improve extinction chronologies, and better understand ancient biodiversity.”

The study, funded by Natural Environment Research Council (NERC),  and led by researchers at The University of Manchester, introduces a more detailed way of simulating how urban areas interact with the atmosphere inside one of the world’s leading models, the Community Earth System Model (CESM), which scientists use to predict how the Earth’s climate behaves now and in the future.

Until now, these large-scale climate and Earth system models have treated cities very simply, grouping them into just a few generic categories such as “high density” or “medium density”. But cities differ enormously with a mix of buildings, roads, vegetation and human activity, which can significantly affect how heat is stored, released and transferred, with knock-on effects for heatwaves, air quality and energy demand.  These factors are often overlooked in current climate predictions and policy decisions.

The new model, published today in the , integrates a detailed urban classification system known as Local Climate Zones (LCZ), which distinguishes between ten types of built environments – from compact high-rise districts to open low-rise neighbourhoods. Each environment is defined by its building height, layout and materials and allows researchers to simulate how cities exchange heat and energy with the atmosphere in much finer detail.

Lead author Dr Zhonghua Zheng, Co-Lead for Environmental Data Science & AI at 91ֱ�� Environmental Research Institute (MERI) and Lecturer in Data Science & Environmental Analytics at The University of Manchester, said: “Cities, which host more than half of the world’s population, are highly vulnerable to the impacts of climate change, but they are also key to sustainable solutions. By using the Local Climate Zones approach, we can now represent the true diversity of urban areas, which is crucial for making accurate climate predictions. Improving how we simulate cities will help researchers and policymakers better understand urban heat stress and energy use, and design more effective strategies for the future.”

Yuan Sun, PhD researcher at The University of Manchester, added: “Incorporating LCZs into ESMs provides a bridge for communication between the environmental model community and urban climate adaptation actors.”

Tests carried out at 20 urban observation sites worldwide, including locations in France, South Korea, the United Kingdom and the Netherlands, showed that the new LCZ-based approach improved the model’s accuracy in simulating key urban heat processes. These include how city surfaces release heat into the atmosphere (known as upward longwave radiation) and the heat generated by human activity, such as air conditioning (known as anthropogenic heat flux), compared with the standard urban scheme.

The study also identified where LCZ-based models could be refined to further improve accuracy.

Sensitivity experiments revealed that rooftop reflectivity has the biggest impact on sunlight and heat in cities, while the layout and shape of streets and buildings, along with roof materials, also play key roles.

Understanding these factors in urban areas could help explain why some areas get hotter than others and could guide future urban design and climate adaptation strategies.

Scientists have developed a simple, low-cost method to drive key chemical reactions, which could make large-scale drug manufacturing, faster, more accessible and affordable.

The new study, published in the journal today by The University of Manchester, describes how complex light or electricity-mediated methods currently used across modern chemistry could be replaced by those driven by a simpler technology - heat.

By heating two common, inexpensive chemicals together, the researchers triggered ‘electron transfer’ reactions that chemists use to make many of our everyday products and medicines.  

Lead researcher, , Lecturer in Synthetic Organic Chemistry at The University of Manchester, said: “Our goal was to develop a broadly accessible and low-cost way to promote electron transfer reactions for industrial applications.

“By using something as simple as heat - something every chemistry lab already has - we’ve created a process that can be scaled more easily and used by companies without the need for expensive, specialised equipment, opening up new possibilities for chemists all over the world.”

Many modern chemical reactions rely on photochemical (light) or electrochemical (electricity) technologies to kick start ‘electron transfer reactions’ – a process that involves transferring electrons between molecules to make medicines, or other essential materials. Although these high-tech methods are powerful and effective, they can be difficult to scale up for industrial use as they require specialist reactors and costly infrastructure.

The 91ֱ�� team’s new approach achieves the same result using only heat and two widely available chemicals - a type of azo compound and a formate salt. When heated together in a standard industrial reactor, these reagents naturally form a highly reactive molecule known as ‘carbon dioxide radical anion’ - a simple yet powerful species capable of driving a wide range of chemical transformations.

Working with Dr James Douglas from AstraZeneca, the research team successfully demonstrated the scalability of the developed method  and tested it on a variety of other chemical reactions used in drug discovery.

, Lecturer in Computational & Theoretical Chemistry at The University of Manchester, added: “Radical chain chemistry underpins so many areas of science and manufacturing, so we hope this simple initiation method will be of wide use across both industry and academia. Beyond large-scale applications, it could also become a valuable tool for researchers studying new chemical reactions.”

On 15-17 September, over 30 leading experts in synthetic biology, mirror biochemistry, sociology, ethics, and tech governance gathered outside of Manchester, U.K. for technical workshops co-hosted by of the University of Manchester and the Mirror Biology Dialogues Fund, a non-profit dedicated to understanding and addressing risks posed by mirror organisms.

Concerns about mirror organisms have been discussed at several recent scientific meetings. A at the Institut Pasteur – detailed in a subsequent – explored how mirror organisms could plausibly evade many mechanisms of immunity and natural ecological controls and pose potentially significant risks to humans, animals, plants, and ecosystems.

Participants at the 91ֱ�� workshop examined four key precursor technologies that could contribute to the creation of mirror organisms. They evaluated the potential benefits of each technology, the extent to which its development would lower barriers to the creation of mirror life, and possibilities for its governance. The technologies examined were:

1. Protein synthesis Using Recombinant Elements (PURE) systems using natural-chirality proteins;
2. Mirror ribosomes;
3. “Crossover” translation systems that enable natural-chirality transcription-translation machinery to produce mirror-image proteins; and
4. The “booting-up” of fully synthetic natural-chirality cells.

“Any governance framework for mirror-image organisms should explicitly preserve beneficial mirror biomolecule research, particularly chemical synthesis of mirror biomolecules,” said Jonathan T. Sczepanski, Professor of Chemistry at Texas A&M University. “Mirror biomolecules are promising candidates for treating diseases that current therapies can’t address effectively. Workshop discussions underscored the importance of drawing boundaries against high-risk applications like creating mirror life, while ensuring that therapeutic and other valuable research can progress.”

No firm conclusions on research boundaries were reached at 91ֱ��, though international discussions on mirror life are ongoing – for example, recent discussions at the U.S. National Academies of Science, Engineering and Medicine explored mirror life, and further engagement is planned at the National University of Singapore in 2026.

“The discussions at 91ֱ�� highlighted how creating mirror life would require major technological advances, but also that researchers are making progress on the underlying technologies,” said Kate Adamala, Associate Professor of Synthetic Biology at the University of Minnesota. “We’re still in a position where it’s possible to stop mirror life from being made, but as these technologies mature, our options for intervention will become more limited.”

“The interdisciplinary nature of these challenges became clear through our discussions,” said Joy Zhang, Professor of Sociology at the University of Kent. “Red lines alone aren’t sufficient – we need a portfolio of governance approaches, including red lines, safety nets, and incentives, that account for the social and ethical dimensions of this technology.”

The Engineering and Safeguarding Synthetic Life (ESSL) on 18 September also featured discussions about mirror organisms. The conference included talks on synthetic cells, genome engineering, and convergence with AI and robotics. Several presentations and a panel discussion examined historical examples of red lines in scientific development; technical and ethical questions about mirror organisms; and scientific discussions since the December 2024 publication of a Science and that first presented the risks of mirror organisms in detail.

“The discussions at 91ֱ�� showed the importance of scientific input and careful analysis in any decision-making around guardrails on research,” said James Smith, Deputy Director of the Mirror Biology Dialogues Fund and adjunct faculty at the J. Craig Venter Institute.

"As this conversation moves to Singapore next year, I’m excited to invite diverse stakeholders from Asia and around the world to join this critical discussion,” said Matthew Chang, Executive Director of the National Centre for Engineering Biology, Singapore, and Professor at the National University of Singapore.

A team from the Department of Mechanical and Aerospace Engineering, working with industry partner Q-Sustain Limited, an engineering consultant based in 91ֱ��, is designing innovative vertical axis wind turbines (VAWTs) that capture airflow generated by trains moving through tunnels – known as the piston effect.

The project, which begins with the Transpennine Route Upgrade project, will explore how this untapped energy source can be integrated into transport infrastructure, providing clean electricity and supporting the UK’s decarbonisation goals.

Early feasibility studies have already confirmed the potential of tunnel airflow, and the team has developed a bespoke techno-economic analysis (TEA) toolkit to evaluate performance and commercial viability of such designs. Available through , the software offers a practical platform for assessing renewable energy projects, with potential applications beyond just rail.

The project, funded under EPSRC Impact Acceleration Account (IAA) and under the remit of ‘sustainable engineering and transport systems’, could transform how transport infrastructure is designed and operated in the future.

Academic Lead of the project at The University of Manchester, said: “Our VerXis toolkit represents a leap forward in renewable energy research. By turning minimal tunnel geometry and schedule data into bank-level economic indicators in minutes, we're bridging the gap between academic innovation and real-world deployment, making piston-wind VAWTs not just technically viable, but genuinely investable.”

Mr Azhar Quaiyoom, Director of industrial partner Q-Sustain Limited, added: “What excites us most about VerXis is its ability to rapidly test and scale turbine designs tailored to each tunnel environment. This toolkit enables smarter, data-driven decisions, helping us deploy sustainable solutions in railway infrastructure that align with the UK's net-zero ambitions and calculates the return on investment for our clients”

The next stage will see prototype turbines tested in real-world tunnel environments, alongside further development of the VerXis toolkit, with the ambition of influencing future rail energy standards.

If successful, the approach could be applied not only to rail but also to other transport networks, providing a scalable model for integrating renewable energy into infrastructure across the UK and beyond.

This surprising finding also contradicts what scientists previously knew about strongly confined water. showed that confined water loses its ability to respond to an electric field, becoming "electrically dead" when measured in the direction perpendicular to surfaces. The new study reveals the complete opposite in the parallel direction – water’s electrical response rises dramatically, by an order of magnitude.

The study, published in by a team led by in collaboration with , used an advanced technique called scanning dielectric microscopy to peer into water's electrical secrets at the true nanoscale. They trapped water in channels so narrow they held only a handful of molecular layers.

The results are striking: bulk water has a dielectric constant around 80, but when thinned to just 1-2 nanometres, its in-plane dielectric constant reaches values close to 1,000 – on par with ferroelectrics used in advanced electronics. At the same time, water's conductivity increases to values approaching those of superionic liquids, materials considered highly promising for next-generation batteries.

"Think of it as if water has a split personality," explains Dr Fumagalli. "In one direction it is electrically dead, but look at it in profile and suddenly it becomes electrically super-active. Nobody expected such dramatic behaviour."

The discovery required the team to develop ultrasensitive measurement techniques capable of probing water layers much thinner than the skin of a virus and track their electrical response across frequencies from kilohertz to gigahertz – spanning six orders of magnitude.

The research also reveals that confined water exists in two distinct electrical regimes. For channels larger than several nanometres, water behaves like its bulk form, albeit with much higher conductivity. But once squeezed to atomic dimensions, it undergoes a sharp transition into a new "superionic-like" state.

This transformation occurs because extreme confinement disrupts water's hydrogen-bond network, which in bulk is a dynamic but rather ordered structure. At the molecular scale this network becomes disordered, allowing dipoles to align more easily with electric fields and enabling rapid proton transport.

"Just as graphene revealed unexpected physics when graphite was thinned down to a single atomic layer, this research shows that even water – the most studied liquid on Earth – can still surprise us when squeezed to its absolute thinnest”, notes Prof Geim, who previously won the Nobel Prize for graphene research.

The implications extend far beyond fundamental science. Insights into water’s electrical properties at the nanoscale are crucial not only for physics and chemistry but also for technologies ranging from advanced batteries and microfluidics to nanoscale electronics and biology.

“Our study changes how we should think about water," adds Dr Fumagalli. "The most ordinary substance on Earth has extraordinary talents that were hidden until now."

The dolphin-sized ichthyosaur called Xiphodracon goldencapensis, or the “Sword Dragon of Dorset” is the only known example of its kind in existence and helps to fill an important gap in the evolutionary fossil record of ichthyosaurs.

Thousands of ichthyosaur fossils have been found along the UK’s Jurassic Coast since the discoveries of pioneering palaeontologist Mary Anning. Yet the discovery of Xiphodracon is the first described genus of an Early Jurassic ichthyosaur described from the region in over 100 years.

Discovered near Golden Cap in 2001 by Dorset fossil collector Chris Moore, the fossil is almost perfectly preserved in three dimensions. The skeleton includes a skull with enormous eye socket and a long sword-like snout. The scientists say the animal would have been about three metres long and would have dined on fish and squid. The remains even show what may be traces of its last meal. It is probably the world’s most complete prehistoric reptile from the Pliensbachian period.

The finding has been described by a trio of international palaeontologists, led by ichthyosaur expert Dr Dean Lomax, an Honorary Research Fellow at The University of Manchester and an 1851 Research Fellow at the University of Bristol, in the journal today.

Dr Lomax said: “I remember seeing the skeleton for the first time in 2016. Back then, I knew it was unusual, but I did not expect it to play such a pivotal role in helping to fill a gap in our understanding of a complex faunal turnover during the Pliensbachian. This time is pretty crucial for ichthyosaurs as several families went extinct and new families emerged, yet Xiphodracon is something you might call a “missing piece of the ichthyosaur puzzle”. It is more closely related to species in the later Early Jurassic (in the Toarcian), and its discovery helps pinpoint when the faunal turnover occurred, being much earlier than expected.”

After its discovery in 2001, the skeleton was acquired by the Royal Ontario Museum, Canada, where it became part of their extensive collection of ichthyosaurs but had remained unstudied.

Ichthyosaurs from the Pliensbachian (193–184 million years ago) are incredibly rare and makes Xiphodracon a vital piece of evidence for scientists studying the critical but poorly understood time in ichthyosaurian evolution.

Ichthyosaur expert and co-author, Professor Judy Massare, from the State University of NY at Brockport, USA, said: “Thousands of complete or nearly complete ichthyosaur skeletons are known from strata before and after the Pliensbachian. The two faunas are quite distinct, with no species in common, even though the overall ecology is similar. Clearly, a major change in species diversity occurred sometime in the Pliensbachian. Xiphodracon helps to determine when the change occurred, but we still don’t know why.”

Dr Erin Maxwell, a co-author and ichthyosaur expert from the State Museum of Natural History Stuttgart, added: “This skeleton provides critical information for understanding ichthyosaur evolution, but also contributes to our understanding of what life must have been like in the Jurassic seas of Britain. The limb bones and teeth are malformed in such a way that points to serious injury or disease while the animal was still alive, and the skull appears to have been bitten by a large predator - likely another much larger species of ichthyosaur- giving us a cause of death for this individual. Life in the Mesozoic oceans was a dangerous prospect.”

Collectively, the trio have identified several features in Xiphodracon that have never been observed in any ichthyosaur. The most peculiar is a strange and unique bone around the nostril (called a lacrimal) that has prong-like bony structures.

Dr Lomax, who is the author of the recently published book, “The Secret Lives of Dinosaurs”, said: “One of the coolest things about identifying a new species is that you get to name it! We opted for Xiphodracon because of the long, sword-like snout (xipho from Greek xiphos for sword) and dracon (Greek and Latin for dragon) in reference to ichthyosaurs being referred to as “sea dragons” for over 200 years.”

The new research has been published today in the international journal “Papers in Palaeontology”. The skeleton is planned to go on display at the Royal Ontario Museum, Toronto, Canada.

Working with colleagues at 91ֱ�� St Mary’s Hospital and the University of Malaysia, the researchers used mathematical modelling to understand how the cord’s unique twisted shape affects the way oxygen, nutrients and heat are exchanged before birth.

The study, published in the , found that the spiral design of the blood vessels in the cord appears to affect the exchange of oxygen and heat, minimising the risk of heat and oxygen being lost, helping to keep babies’ temperature and oxygen levels stable before birth.

Although the umbilical cord is essential to life, scientists still know little about how its complex coiled structure contributes to its function. These new findings shed light on an overlooked but vital process.

Complications linked to the placenta and umbilical cord, such as fetal growth restriction and pre-eclampsia, affect around 10% of pregnancies in the UK, yet remain poorly understood.

The researchers hope their work will pave the way for further studies on abnormal cord structures, such as cords that are too loosely or tightly coiled, which are known to be associated with complications during pregnancy.

The project, supported by a £3 million grant from the Gates Foundation, will develop national-scale irrigation mapping data and capacity in three countries – Kenya, Ethiopia, and Nigeria – between September 2025 and August 2029.

Expanding and improving irrigation access is vital for climate adaptation and food security across Sub-Saharan Africa (SSA). Yet, most SSA countries lack up to date or reliable information about existing irrigation systems, leaving governments and development actors limited in their ability to target interventions to improve irrigation access, evaluate outcomes of investments, and ensure development is both sustainable and equitable.

The new project – IrrEO: Irrigated Area Mapping Tool Development and Deployment – will leverage advances in Earth Observation (EO) imagery and artificial intelligence algorithms, working with national partners in the three focal countries to co-develop a set of data products, algorithms, and software that enable high-resolution mapping of irrigated croplands both now and into the future.

The project will also work with local research teams to use new irrigation mapping data and tools to understand the barriers and opportunities for irrigation development, highlighting investment strategies that deliver better results for small-scale farmers.

Another key goal is to strengthen the capacity of government agencies and development partners across Sub-Saharan Africa to apply advanced mapping approaches in national irrigation planning. Over four years, the team will conduct training workshops and participatory design session to help overcome barriers to adopt of EO methods and tools in irrigation decision-making and policy.

The University team brings together interdisciplinary expertise in remote sensing, agricultural sustainability, rural development, and data justice. Alongside , the other 91ֱ�� team members include , Senior Lecturer in Physical Geography from the School of Environment Education and Development (SEED) and co-lead of MERI’s newly launched Land and Resource Futures Initiative – and , Senior Lecturer in Socio-Environmental Systems in the Global Development Institute (GDI).

Organised in partnership with Rethink Rebuild Society and supported by the Chemists’ Community Fund (Royal Society of Chemistry), 48 children aged nine to 14 visited the University’s state-of-the-art Makerspace facility over three days to take part in a variety of fun and practical experiments, including making batteries out of lemons, testing acidity with natural indicators, and simple filtration experiments.

The initiative is the brainchild of Dr Abdullatif Alfutimie, Senior Lecturer in the School of Chemical Engineering at the University. Dr Alfutimie first came to 91ֱ�� from Aleppo in 2009 to pursue postgraduate study before going on to complete his PhD in 2012. But while pursuing his research career, his home city of Aleppo – once one of Syria’s most vibrant cultural centres – was being devastated by civil war.

Staying closely connected to family and friends affected by displacement and the collapse of education, he began to consider how he might use his own expertise to help displaced students regain educational confidence.

Dr Abdullatif Alfutimie, who led the programme, said: “This event wasn't just about science — it was about recognising curiosity, celebrating identity, and creating a sense of belonging for children who often face immense challenges.

"If we need to rebuild our country or even to contribute to improve this country, we need to educate this generation.

“The enthusiasm from the pupils was truly heartwarming - one parent told us that their child couldn't wait to repeat an experiment at home for their siblings.”

The initiative concluded with a Community Celebration Day at Rethink Rebuild Society’s centre in 91ֱ��, welcoming more than 150 children and family members. Each child received a certificate and a take-home chemistry kit to continue their learning at home. A representative from the Royal Society of Chemistry was also in attendance to present the certificates and celebrate the children’s achievements.

Magda van Leeuwen, Volunteer and Engagement Manager for the Royal Society of Chemistry, said: “Chemistry Education for Refugee Students is an important initiative that gives young people who have already experienced a lot in their lives hope and opportunities. Programmes like the one Abdullatif has developed show that chemistry really is for all and can be a catalyst for instilling a lifelong passion in our subject.

“Through the Outreach Fund and with the backing of the Chemists’ Community Fund, the RSC is committed to supporting projects that give more people the opportunity to get hands-on scientific experiences. We are proud to have played a small part and want to applaud Abdullatif and his colleagues for their hard work in putting together such a practical and engaging experience for the participants.”

The University of Manchester is recognised as a University of Sanctuary, working to make the University a welcoming and safe place for refugees and asylum seekers. The University’s commitment to supporting sanctuary seekers is embedded across its three core goals: research, teaching, and social responsibility. The city of Manchester is also a City of Sanctuary, part of the . The University works closely with the organisation to help its aim of making 91ֱ�� a place that is open and fair.

’, published to mark the Centre’s 25th anniversary, looks back at the Tyndall Centre’s own energy scenarios, alongside more than 80 others produced in the 2000s. The study found that while most scenarios assumed some level of reduction in energy demand, only one -  Tyndall Centre’s “Red” scenario - came close to predicting the UK’s actual energy demand in 2022.

The researchers say this mismatch reveals that early scenarios often focused on untested technologies while overlooking practical and proven ways to reduce energy use, such as improving public transport, insulating homes, and reducing air travel.

They identified that these modelling choices often influenced policy debates, with optimism about new technologies often overshadowing everyday solutions, potentially limiting the scope of decarbonisation deemed possible by policymakers.

 By comparing the envisioned futures with the UK energy system changes that actually emerged, the authors show where foresight was limited, where assumptions proved overambitious, and where genuine transformation was underestimated.

The report also reflects on two decades of Tyndall Centre’s research. Starting with the Royal Commission’s 60% carbon cut target by 2050, the Tyndall Centre helped bring carbon budgets to the centre of UK climate policy and highlighted the need for action across all sectors, including aviation and shipping,.

The authors argue that energy scenarios aiming to support an urgent reduction in greenhouse gas emissions, must explore a wider range of options, with greater focus on proven solutions such as efficiency, lifestyle change, and equity. Doing so would open up more options for policymakers to deliver on their climate ambition, reduce reliance on unproven technologies, and align the UK’s energy pathways more closely with climate science.

Decarbonising the UK revisited is being launched at the Tyndall Centre’s 25^th Anniversary Conference at the University of East Anglia (UEA) on Monday, 8 September. Our Critical Decade for Climate Action is a major meeting for 300 researchers from 20 countries.

The report is part of a wider project at Tyndall Centre that explores how energy scenarios influence policy and what lessons can be drawn halfway through this critical decade for climate action.

In a new review, published in the journal today, the researchers have examined the current scientific research on how tiny plastic fragments – called micro and nanoplastics – enter the air, where they come from, and the mechanisms that transport them across vast distances.

The study reveals significant gaps in knowledge and understanding of airborne plastic pollution, driven by inconsistent measurement techniques, limited data, oversimplified simulations, and gaps in understanding atmospheric cycling mechanisms.

One key uncertainty is the scale of plastic entering the atmosphere. Current estimates vary wildly - from less than 800 tonnes to nearly 9 million tonnes per year - making it difficult to assess the true global impact. It also remains unclear whether the dominant contributors are land-based, such as road traffic, or marine based, such as sea spray.

Such large uncertainties raise the concern that airborne plastics, which pose potential risks to human and environmental health, may have a more extensive presence and influence than previously captured by current monitoring and simulation systems.

Each year, the world produces over 400 million tonnes of plastic, with a significant proportion ending up as waste. Over time, these plastics breaks down into microscopic particles called microplastics (less than 5mm) and nanoplastics (smaller than 1 micron), which are increasingly being found in the air we breath, oceans and soil. These particles can move thousands of miles within days and have even remote regions like polar ice zones, desserts and remote mountain peaks.

While our understanding of the problem has grown rapidly, limited real-world data, inconsistent sampling methods, and computer models that oversimplify how plastic behaves in the air, means that key questions remain unanswered.

To address these concerns, the authors are calling for future research efforts to focus on three critical areas:

• Expanding and standardising global observation networks
• Improving and refining atmospheric modelling
• Harnessing the power of artificial intelligence (AI)

They say this integrated approach could transform how we understand and manage the plastic pollution crisis.

Located around 3,400 light-years away in the constellation Scorpius, the Butterfly Nebula is one of the best studied planetary nebulae. Its ‘wings’ of glowing gas were previously but Webb’s new observations, published in today, go even further, uncovering hidden structures and finally pinpointing the nebula’s elusive central star.

Planetary nebulae like the Butterfly form when stars heavier than the sun reach the end of their lives, casting off their outer layers of gas and dust. The Butterfly Nebula is what astronomers call a bipolar nebula, meaning that it has two lobes of gas that spread in opposite directions to form the ‘wings’ of the butterfly. At its centre, a dense band of dusty gas called the torus, which poses as the butterfly’s ‘body’. This structure energises the nebula and may be responsible for its insect-like shape by preventing gas from flowing evenly in all directions. 

Using James Webb’s , scientists have now been able to see through this dusty torus for the first time, providing an unprecedented view of its complex structure.

By combining images at many different wavelengths with complementary data from the Atacama Large Millimetre/submillimetre Array in Chile, the international team of researchers, including from The University of Manchester, discovered  the butterfly’s central star, one of the hottest ever found in our galaxy, with a scorching surface temperature of around 220,000 Kelvin.

Although this intense heat powers the nebula’s colourful glow, earlier telescopes lacked the sensitivity and resolution needed to see through the thick layer of dust, making the star impossible to detect at visible wavelengths.

Professor Albert Zijlstra, a co-author of the paper from The University of Manchester, said: “This is an extraordinary discovery. We’re looking at one of the hottest stars ever found - an object so elusive that even Hubble couldn’t detect it for decades. Thanks to JWST, we’ve finally uncovered it, concealed within its own dense shroud of dust.

“Surrounding the star is a massive dark torus, the heaviest ever observed around such an object, containing more material than our own Sun. Even Webb can’t fully pierce through it. Inside, the environment is sheer chaos; powerful radiation and stellar winds tearing into the surrounding cloud. It’s unlike anything I’ve ever seen.

“Most planetary nebulae appear graceful and symmetric, but this one is still at the beginning of its transformation – it’s more like a butterfly struggling out of its cocoon than the elegant shapes we’re used to seeing.”

The Webb data revealed that the torus is composed of crystals similar to quartz as well as unusually large grains of dust, suggesting they have been growing for a long time. Outside the torus, the team observed jets of iron and nickel blasting away from the star in opposite directions, along with a multilayered structure made up of different atoms and molecules.

Perhaps most intriguing was the discovery of carbon-based molecules known as polycyclic aromatic hydrocarbons, or PAHs. On Earth, these molecules are found in smoke from fires or even burnt toast – but they have never before been seen in an oxygen-rich planetary nebula. The team believes the PAHs may form when a bubble of stellar wind bursts into the surrounding gas.

The finding provides an important glimpse into the details of how these molecules form.

A series of three new papers published this week in Nature Astronomy and Nature Geoscience, reveal that Bennu is a mix of dust formed in our solar system, organic matter from interstellar space and stardust that predates the solar system itself. The asteroid is thought to have formed from fragments of a larger parent asteroid destroyed by a collision in the asteroid belt between the orbits of Mars and Jupiter.

In the first paper, co-led by researchers at the University of Arizona and NASA’s Johnson Space Center, published in the journal , 91ֱ�� researchers studied the gases trapped inside Bennu’s samples – in particular xenon, which is a very rare gas. Their measurements showed that Bennu’s gases resembled those found in some of the most primitive meteorites found on earth and materials returned from asteroid Ryugu by Japan’s Hayabusa2 mission.

When combined with other elemental and isotopic analyses, the results suggest that Bennu’s parent body contained material from a range of origins, close to the Sun, far from the Sun, and even some grains from beyond our solar system.

The findings also show that while much of the materials in the parent asteroid had been affected by water and heat, some of the material had escaped various chemical processes and retained its original chemical signatures. Some even survived the extremely energetic collision that broke it apart and formed Bennu.

The studies also show that while some of Bennu’s original material survived unchanged, similarly, much of it was transformed by reactions with water. Minerals in its parent asteroid likely formed, dissolved, and re-formed over time, with up to 80% of Bennu’s material now made up of water-bearing minerals.

These findings were reported in a second paper the paper published in co-led by the University of Arizona and the Smithsonian’s National Museum of Natural History, and included contributions from Professor Rhian Jones at The University of Manchester.

In the third paper, co-led by Lindsay Keller at NASA’s Johnson Space Center and Michelle Thompson of Purdue University, also published in , researchers found microscopic craters and tiny splashes of once-molten rock – known as impact melts – on the sample surfaces - signs that the asteroid was bombarded by micrometeorites. These impacts, together with the effects of solar wind, are known as space weathering and occurred because Bennu has no atmosphere to protect it.

Lindsay Keller at NASA’s Johnson Space Center, said: “The surface weathering at Bennu is happening a lot faster than conventional wisdom would have it, and the impact melt mechanism appears to dominate, contrary to what we originally thought.

“Space weathering is an important process that affects all asteroids, and with returned samples, we can tease out the properties controlling it and use that data and extrapolate it to explain the surface and evolution of asteroid bodies that we haven’t visited.”

As leftovers from the formation of planets 4.5 billion years ago, asteroids like Bennu provide a valuable record of solar system history. Unlike meteorites that fall to Earth, which often burn up or are altered in the atmosphere, Bennu’s pristine samples give scientists a rare opportunity to study untouched material.

The project brings together researchers from NASA, universities and research centres around the world – including the UK, the United States, Japan and Canada – to study Bennu’s samples and unlock new insights into the origins of the solar system.

The breakthrough, reported in by a team led by Professor Andre Geim, was achieved by placing a sheet of graphene just three atoms below cleaner bulk graphite. This “proximity mirror” cancels out unwanted electric fields, reducing disorder in graphene by a factor of 100.

"Think of it like creating the ultimate clean room, but for electrons," explains first author Dr Daniil Domaretskiy. "We’ve removed almost all the ‘dirt’ that disrupts smooth flow of electric current. You can suddenly see effects that were hidden, like wiping clean a fogged-up window."

In quantum materials, disorder hides delicate effects and can prevent new physics from emerging. Researchers normally go to great lengths to remove impurities and minimise interference, but in graphene the team has now pushed this to an extreme: just one uncontrolled electron per 100 million carbon atoms remains across an entire device.

This record-low disorder means that electrons travel faster and further than ever before. Key benchmarks of material quality, such as Shubnikov–de Haas oscillations, are now visible at fields below 10 Gauss. The celebrated quantum Hall effect appears below 50 Gauss, far weaker than a fridge magnet.

The concept is straightforward: the nearby graphite acts like an electrical mirror, cancelling random electric fields in the graphene layer. The challenge was engineering the mirror close enough, three atoms apart, without damaging the graphene.

“Now that we know how to make things this clean, it opens the door to exploring phenomena that were out of reach,” said co-author Dr Zefei Wu. “This is just the beginning.” 

The team expects their ‘proximity-mirror’ technique to become standard for probing quantum phenomena in two-dimensional materials, enabling new discoveries in superconductivity, magnetism and exotic quantum phases, which would all benefit from the ultraclean electronic conditions to clearly emerge.

The work involved collaborators from Lancaster University, the National University of Singapore, and the National Institute for Materials Science in Japan.
