Researchers from Japan and Taiwan reveal for the first time that helium, usually considered chemically inert, can bond with iron under high pressures. They used a laser-heated diamond anvil cell to find this, and the discovery suggests there could be huge amounts of helium in the Earth’s core. This could challenge long-standing ideas about the planet’s internal structure and history, and may even reveal details of the nebula our solar system coalesced from. If you’ve ever seen a volcanic eruption and wondered what might be coming ...

On May 6, 1954, Roger Bannister pushed through the finishing tape at Iffley Road track in Oxford, England, and collapsed into the arms of friends after becoming the first human to run a mile in less than four minutes. “It was the running equivalent to summiting Mount Everest for the first time,” said University of Colorado Boulder Integrative Physiology Professor Rodger Kram. “Prior to Bannister, it was considered impossible—beyond the limits of human physiology.” Seven decades later, a female runner has yet to follow ...

A high dietary intake of lean and oily fish may slow the progression of disability in people with multiple sclerosis (MS), suggests a comparative population based study, published online in the Journal of Neurology Neurosurgery & Psychiatry.   The anti-inflammatory and neuroprotective properties of the nutrients found in fish may be key, say the researchers, who add that their findings underscore the potential importance of diet in managing the disease. Emerging evidence indicates that diet may have a role in the development of inflammatory diseases, including MS, explain the researchers.  While previously published research has linked fish ...

UK Armed Forces servicewomen needing an abortion face a unique set of hurdles around access and care, as well as stigma and judgemental attitudes from senior (usually male) colleagues, indicates the first study of its kind, published online in the journal BMJ Sexual & Reproductive Health.   Although based on a relatively low response rate, the findings prompt the researchers to call for more information and policy on abortion provision, both for service personnel and military healthcare professionals. In the UK around 1 in 3 women ...

The use of powerful synthetic opioids, such as sufentanil and remifentanil, during surgery is linked to a subsequent poor ‘pain experience’---a composite of emotional, cognitive, and physical aspects of pain— suggests research published in the open access journal Regional Anesthesia & Pain Medicine.   The findings highlight the need to reassess intraoperative pain relief strategies to reduce complications after surgery and improve the quality of patient care, say the researchers. Most patients ...

Millions of people with type 2 diabetes could receive better treatment thanks to a new, simple low-cost tool, according to groundbreaking research announced today at the Diabetes UK Professional Conference 2025 and published in the Lancet. Researchers at the University of Exeter, funded by the Medical Research Council, Wellcome and NIHR Exeter Biomedical Research Centre, and supported by Diabetes UK, have developed an innovative way of identifying the most effective glucose-lowering drugs for a person with type 2 diabetes. By predicting which drug will lead to the largest reduction in blood glucose ...

Peer reviewed/ Simulation/modelling /People   A new AI model can flag female patients who are at higher risk of heart disease based on an electrocardiogram (ECG).   The researchers say the algorithm, designed specifically for female patients, could enable doctors to identify high-risk women earlier, enabling better treatment and care. Details are published today in Lancet Digital Health.   An ECG records the electrical activity of the heart and is one of the most common medical tests in the world. In ...

Our organs age at different rates, and a blood test determining how much they’ve each aged could predict the risk of conditions like lung cancer and heart disease decades later, finds a new study led by University College London (UCL) researchers. The findings, published in The Lancet Digital Health, show how accelerated ageing in specific organs can predict not only diseases affecting that organ, but diseases across the rest of the body as well. Lead author Professor Mika Kivimaki (UCL Faculty of Brain Sciences) said: “Our organs function as an integrated system, but they can age at different rates. ...

A new species of manzanita — a native California shrub famous for its twisted branches and wildfire resilience — has been discovered on the central coast, but its survival is already threatened by urban development that could destroy much of its fragile population. The discovery is detailed in a new study published in PhytoKeys, where researchers used genetic analysis to confirm the plant as a distinct species. Named Arctostaphylos nipumu to honor the Nipomo Mesa where it was discovered and its indigenous heritage, the species stands out for its shaggy gray bark — ...

New Curtin University research has revealed how massive ancient glaciers acted like giant bulldozers, reshaping Earth’s surface and paving the way for complex life to flourish. By chemically analysing crystals in ancient rocks, the researchers discovered that as glaciers carved through the landscape, they scraped deep into the Earth’s crust, releasing key minerals that altered ocean chemistry. This process had a profound impact on our planet’s composition, creating conditions that allowed ...

(Santa Barbara, Calif.) — From integrated photonics to quantum information science, the ability to control light with electric fields — a phenomenon known as the electro-optic effect — supports vital applications such as light modulation and frequency transduction. These components rely on nonlinear optical materials, in which light waves can be manipulated by applying electric fields.  Conventional nonlinear optical materials such as lithium niobate have large electro-optic response but are ...

UdeM reproductive biologist Greg FitzHarris and his team show for the first time that sister cells can communicate with each other through a bridge that allows them to die in a coordinated way. Sister cells are a pair of cells that share the same mother cell. In a new study published in Developmental Cell, researchers led by Université de Montréal (UdeM) professor Greg FitzHarris show how the early mouse embryo gets rid of the defective or unneeded cells in pairs. “Such a mechanism could serve to ensure the elimination of cells with a ...

Identifying and delineating cell structures in microscopy images is crucial for understanding the complex processes of life. This task is called “segmentation” and it enables a range of applications, such as analysing the reaction of cells to drug treatments, or comparing cell structures in different genotypes. It was already possible to carry out automatic segmentation of those biological structures but the dedicated methods only worked in specific conditions and adapting them to new conditions was costly. An international ...

AURORA, Colo. (Feb. 25, 2025) – A new study, published today in The Lancet Respiratory Medicine, tested whether a set of interventions to keep lungs expanded before, during, and after abdominal surgery could lower the risk of serious breathing problems in patients compared to the usual care at 17 academic hospitals in the U.S. The research has determined that these interventions for open abdominal surgery do not result in less severe breathing problems as compared to the usual care in those hospitals. Adult abdominal surgery patient enrollees were either given a lung expansion set of interventions or the typical care plan to follow at each hospital. ...

How can the loss of species and habitats in agricultural landscapes be stopped? Up to now, measures have mostly been implemented by individual farms. In contrast, agri-environmental measures that are planned across farms at landscape level offer greater potential for creating suitable habitats for different species as a mosaic in the landscape. However, successful landscape level approaches also require cooperation between farms and other stakeholders from local governments, politics and nature conservation. Researchers at the University of Göttingen have therefore identified ...

LA JOLLA, CA—Scientists at La Jolla Institute for Immunology (LJI) have found a potential new target for treating Parkinson's disease. Their new research reveals how a protein in brain cells may drive Parkinson's onset—and offers a possible explanation for why Parkinson's is much more common in men.  In recent years, LJI scientists have found increasing evidence that autoimmunity plays a role in the onset of Parkinson's disease. Their recent study in The Journal of Clinical Investigation shows that PINK1 appears to mark ...

WASHINGTON—The Society for Cardiovascular Angiography & Interventions (SCAI) has published an expert consensus statement that provides interventional cardiologists, cardiothoracic surgeons, and heart teams with practical guidance for selecting patients and performing alternative access transaortic valve replacement (TAVR). TAVR has seen substantial growth over the past decade, becoming a standard of care for many patients with asymptomatic aortic stenosis. However, some patients face challenges due to inadequate femoral vascular access. The new guidelines address this gap by recommending alternative access ...

The efficient architecture of our joints, which allows our skeletons to be flexible and sturdy, originated among our most ancient jawed fish ancestors, according to a study published February 25th in the open-access journal PLOS Biology by Neelima Sharma of the University of Chicago and colleagues. Synovial joints are a key feature of most vertebrate skeletons, providing more mobility and stability compared to other joint types. A synovial joint allows bones or cartilage to slide past each other with the aid of a lubricated cavity between them. These joints are present in land vertebrates and bony fish, suggesting this feature had evolved in the common ancestors of these groups, but ...

A world of microbes resides within the gut of every human being. This vast microbial community, the microbiome, which includes bacteria and viruses, has repeatedly demonstrated its ability to actively contribute to both health and disease. Researchers have learned a good deal about the bacterial communities that live in the human gut. For instance, they have discovered that these bacteria extensively metabolize the food we eat, drive normal development of the immune system and, to our detriment, include some opportunistic microorganisms that can cause disease under certain conditions. On the other hand, the contributions of viruses in the gut microbiome ...

WHAT: Lowering the body temperature of preterm infants (born at 33 to 35 weeks of pregnancy) with hypoxic ischemic encephalopathy (HIE)—a type of brain damage caused by oxygen loss—offers no benefits over standard care, according to a study funded by the National Institutes of Health (NIH). Previous studies of near-term and term infants (born after 36 weeks) with HIE found that this cooling treatment, which lowers body temperature to about 92 degrees Fahrenheit, significantly reduced the risk of death or disability by age 18 months (corrected for prematurity). However, the current findings show ...

BATON ROUGE – When faced with multiple food options and ultimately choosing one, the factors of that decision-making process may be more physiological than previously assumed. A group of scientists led by Pennington Biomedical Research Center’s Dr. Christopher Morrison recently discovered that the hormone fibroblast growth factor 21, or FGF21, plays an influential role in brain reward mechanisms like those involved in dietary choices.   The discovery was announced in the research team’s recent paper titled “FGF21 ...

As electric vehicles (EVs) gain momentum in the fight against climate change, the conversation around public charging infrastructure is growing increasingly complex. Xinwu Qian , assistant professor of civil and environmental engineering at Rice University, is spearheading research that reimagines how and where charging stations should be deployed — ensuring that alignment with people’s daily routine and activities, beyond mere accessibility, are at the forefront. “Charging an electric vehicle isn’t just about plugging it in and waiting — it takes 30 minutes to an hour even with the fastest charger ...

On Wednesday 26 February, a thermal imaging camera built by researchers at the University of Oxford’s Department of Physics will blast off to the Moon as part of NASA’s Lunar Trailblazer mission. This aims to map sources of water on the Moon to shed light on the lunar water cycle and to guide future robotic and human missions. Once in orbit, the spacecraft – weighing 200kg and about the size of a washing machine- will map the surface temperature and composition of the ...
