The Interactions Collaboration has announced the winning images of the 2025 Global Physics Photowalk. These photographs transform the invisible frontier of particle physics — from a detector hunting for dark matter a few thousandths of a degree above absolute zero, to a deep-sea neutrino telescope studying violent astrophysical phenomena — into visual testaments that capture the beauty, precision and nature of humankind’s search to understand the universe.  Selected from hundreds of images submitted by more than 100 amateur and professional photographers across the U.S., Europe and Asia, the Global ...

Exercise does more than strengthen muscles; it also rewires the brain. In a study publishing February 12 in the Cell Press journal Neuron, researchers reveal that the lasting gain in endurance from repeated exercise—such as the ability to run farther and faster over time—involves changes in brain activity that help muscles and hearts to become stronger.   “A lot of people say they feel sharper and their minds are clearer after exercise,” says corresponding ...

About The Study: In this nationwide cohort of U.S. veterans with type 2 diabetes, semaglutide initiators had a 2-fold nonarteritic anterior ischemic optic neuropathy (NAION) risk than sodium-glucose cotransporter-2 inhibitor initiators, while the absolute risk was low. Clinicians and patients should be counseled on the rare but evident increased risk of NAION after semaglutide initiation.  Corresponding Author: To contact the corresponding author, Jennifer S.

Our past experiences shape how much we eat and where and what we choose to eat. Using preclinical models, researchers from Mass General Brigham and the Broad Institute of MIT and Harvard have identified brain cells that translate contextual information into appetite control. The findings suggest that dysfunction in this brain circuit could be a factor in disordered eating and obesity, meaning that these neurons could be a new target for treatment. Results are published in Neuron. “We identified a neural circuit that is responsible for linking our prior experiences with ...

When the time is right, a good love song can make all the difference.  A study from the University of California, Davis, found that temperature affects the sound and quality of male frogs’ mating calls. In the colder, early weeks of spring, their songs start off sluggishly. In warmer weather, their songs pick up the pace, and female frogs take note.  Better songs not only make the males more attractive mates, but they also suggest to females that environmental conditions are suitable for reproduction.  “The song of frogs really depends on the temperature of the environment,” said lead ...

A new study has used ancient DNA to reveal that hunter-gatherers in Belgium, the Netherlands and nearby parts of Germany adapted to farming thousands of years later than elsewhere in Europe. It has also uncovered the pivotal role of women in the process.   The research, published in Nature, involved scientists from Bournemouth University (BU) and the University of Huddersfield and was led by David Reich ...

WASHINGTON — Researchers have developed a highly sensitive light-based sensor that can detect extremely low concentrations of cancer biomarkers in the blood. The new technology could one day make it possible to spot early signs of cancer and other conditions using a simple blood test. Biomarkers such as proteins, DNA or other molecules can be used to reveal the presence, progression or risk of cancer and other diseases. However, one of the main challenges in early disease diagnosis is the extremely low concentration of biomarkers present at the onset. “Our sensor combines ...

OAK BROOK, Ill. — With a new MRI technique that shows both heart tissue and blood flow simultaneously, physicians can see where heart defects occur and precisely plan to repair them, according to new research published today in Radiology: Cardiothoracic Imaging, a journal of the Radiological Society of North America (RSNA). Researchers at Children’s Hospital of Philadelphia (CHOP) in Pennsylvania have developed 3D volume rendering methods for cardiac MRI that display complex structures within the heart and show how blood moves through them, much like ultrasound images ...

Scientists have identified a pattern of gene activity present in some female survivors of childhood abuse that is associated with an elevated risk of depression. “We know childhood abuse increases the risk of depression at the population level, but at the individual level it’s much harder to predict who will actually develop the disorder,” said senior author Patricia Silveira, professor in McGill’s Department of Psychiatry and researcher at the Douglas Mental Health University Institute. “Our findings point to a biological mechanism that may help explain who is more at risk, at least in women.” This pattern ...

Researchers at McGill University and the United States Forest Service have found that plants living in areas where human activity has caused population crashes carry long-lasting genetic traces of that history, such as reduced genetic diversity. Because genetic diversity helps species adapt to climate change, disease and other stresses, the study suggests it is vital to consider a population’s history-influenced genetics alongside its size and habitat in conservation planning. “Two populations may look equally healthy on the surface, yet one may be far more vulnerable to future environmental change because it lacks genetic diversity and consists of individuals with ...

DALLAS, Feb. 12, 2026 — When a medical emergency happens, time matters and a quick response is needed[1]. During American Heart Month 2026, the National Fraternal Order of Police joins the American Heart Association in urging Americans everywhere to be the help until help arrives and learn how to respond in a medical emergency such as cardiac arrest – when providing help like cardiopulmonary resuscitation (CPR) can be the difference between life and death. For the fourth consecutive year, American Heart Month highlights the need to be prepared in an emergency and provide CPR because immediate action can change outcomes. In fact, providing ...

A new national study finds a concerning surge in teen “sexting,” which frequently exposes them to serious risks, including sextortion, coercion and privacy violations. Sexting involves sending or receiving sexually suggestive images or video, while sextortion is the threat to share explicit or intimate images without consent to pressure someone into providing more images, sexual favors, money or other demands. Sextortion is especially harmful for teens, who are still developing impulse control, risk assessment and emotional regulation. Using a national sample of 3,466 adolescents aged 13 to 17 years in the United States, researchers from Florida ...

Liver cirrhosis, the common endpoint of chronic liver disease, is characterized by diffuse fibrosis, pseudolobule formation, and vascular distortion. Its clinical spectrum ranges from asymptomatic early stages to advanced disease with severe complications like ascites, variceal bleeding, hepatic encephalopathy (HE), hepatorenal syndrome (HRS), and hepatocellular carcinoma (HCC). To address evolving clinical needs and integrate the latest evidence, the Chinese Society of Hepatology has updated the 2019 guidelines, renaming ...

The case describes Rentosertib as the world’s ...

As the world is moving towards more sustainable energy solutions, the emergence of next-generation batteries is a crucial and indispensable milestone. One such next-generation battery is the lithium-ion battery (LIB), which has been currently dominating the energy solutions sector. However, lithium is sparsely distributed across geographies, increasing extraction difficulties and battery production cost. Other next-generation batteries, such as sodium-ion batteries (NIBs) and potassium-ion batteries (KIBs), are promising alternatives to LIBs, offering resource-unconstrained, cost-effective, and sustainable ...

Cancer researchers working on immunotherapies have made a big discovery: SLAMF6, a molecule on the surface of immune cells that prevents T cells from effectively attacking tumours – and, in mice, they've found a way to neutralize it.  Led by Université de Montréal medical professor Dr. André Veillette, director of the molecular oncology research unit at the UdeM-affiliated Montreal Clinical Research Institute (IRCM), the breakthrough is detailed in a study published in Nature. An internal brake independent of tumor cells In their lab, Veillette and his team demonstrated that, ...

Artificial intelligence is increasingly able to simulate human behavior and answer online surveys and political polls, putting the reliability of survey-based research at risk. Consequences can be serious not only for science and research - online surveys are a cornerstone of modern social-science research - but also for policy and participation of people in democratic processes, as surveys are widely used in political polls. This is a worry expressed in a comment in Nature by three researchers ...

Ambitious climate action to improve global air quality could save up to 1.32 million lives per year by 2040, according to a new study. The research, led by Cardiff University, shows how developing countries rely heavily on international cooperation to see these benefits, because much of their pollution originates outside their borders. The first-of-its-kind study analysed these cross-border pollution “exchanges” for nearly every country – 168 in total. Their findings, published in Nature Communications, reveal how a fragmented world, with little collaborative climate mitigation policymaking, would lead ...

Kyoto, Japan -- The enzyme Na⁺-NQR is a sodium pump that drives the respiration of many marine and pathogenic bacteria. Using redox reactions, the process of exchanging electrons between materials, it powers the transportation of sodium ions across the membrane, supporting the growth of the bacteria. Yet there is a mystery behind this mechanism, as scientists have had trouble understanding exactly how the redox reactions are linked to sodium-pumping. In particular, the lack of structural information on the key intermediate states that form while the enzyme is operating has posed a major challenge; determining these structures is essential to understanding how the ...

Atrial fibrillation (AF), the most common chronic cardiac arrhythmia in clinical practice, is very challenging to treat once it becomes persistent, after which spontaneous return to normal rhythm becomes highly unlikely. A multidisciplinary study led by the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) and published in Circulation Research now provides a new perspective on why this arrhythmia can persist long-term, highlighting the key role of non-contractile cardiac cells. AF has traditionally been viewed as a purely electrical disorder of cardiomyocytes—the heart’s contractile cells. However, the ...

Ghent, 12 February 2026 – VIB and Ghent University researchers have identified and characterized a previously unknown cellular barrier in the brain, which sheds new light on how the brain is protected from the rest of the body. In a study published in Nature Neuroscience, the scientists also reveal a new pathway by which the immune system can impact the brain. Prof. Roosmarijn Vandenbroucke (VIB–UGent Center for Inflammation Research): “These findings reveal how vulnerable and protectable the brain is, opening new perspectives for more targeted interventions in brain disorders.” The ...

In rural regions of Africa, high blood pressure often goes untreated because health centres are far away and there is a shortage of health professionals. A study in Lesotho shows that, with the help of a tablet app, villagers who have received training achieve better blood pressure control in their village community compared to normal treatment in healthcare facilities. The results provide the first robust data for an approach that could significantly improve access to blood pressure treatment in underserved regions. ...

Scientists at the University of Pittsburgh School of Medicine discovered a surprising new way the body can fight insulin resistance and diabetes – by boosting a special type of “good” immune cell in fat tissue. Announced today in Nature Communications, the preclinical findings pave the path to develop a medication to treat and prevent type 2 diabetes, potentially replacing or supplementing GLP-1 weight maintenance drugs that lose effectiveness over time. “One-third of our population is obese or overweight – over the next decade or so, ...
