Rhythmic electrical activity in the retina (known as pathological oscillations) has been observed in several eye diseases, including congenital stationary night blindness (CSNB) and retinitis pigmentosa (RP). These oscillations interfere with the normal transmission of visual information to the brain, often causing degraded or distorted perception. Although scientists have long known that such oscillations occur in retinal ganglion cells (RGCs), the neurons responsible for sending visual signals to the brain, the cellular mechanism that drives this rhythmic activity has remained elusive. In a recent study published online in The Journal of General Physiology on October 16, ...

In magnetic materials with antisymmetric exchange interactions, novel particle-like spin textures called magnetic skyrmions can appear and be manipulated by electrons. First observed in 2009, they have been created and controlled at room temperature in many materials. Skyrmions, as nonvolatile information carriers, are key in electronic and spintronic devices. Their size can be just a few nanometers, enabling high storage densities. They require low current to move, are topologically stable, and offer nonvolatility and radiation hardness for extreme environments. Over the past decade, most published reports in the field, both experimental and theoretical, have focused on the applications ...

In light of the ongoing fifteen-year megadrought in Chile, an international team of researchers, including Francesca Pellicciotti from the Institute of Science and Technology Austria (ISTA), addressed a bold future scenario. Their findings: by the end of the century, the considerably worn-out glaciers will not be able to buffer a similar megadrought. They call for coordinated global climate policies to develop effective water management strategies. The results were published in Communications Earth & Environment. Could a drought have no end? Fifteen years of severe and persistent drought in Chile have already passed, and the country ...

Irvine, Calif., Nov. 18, 2025 — Researchers at the University of California, Irvine and NASA’s Jet Propulsion Laboratory have identified stormlike circulation patterns beneath Antarctic ice shelves that are causing aggressive melting, with major implications for global sea level rise projections. In a paper published recently in Nature Geoscience, the scientists say their study is the first to examine ocean-induced ice shelf melting events from a weather timescale of just days versus seasonal or annual timeframes. This enabled them to match “ocean storm” activity with intense ice melt at Thwaites Glacier ...

Deep brain stimulation – implants in the brain that act as a kind of ‘pacemaker’ – has led to clinical improvements in half of the participants with treatment-resistant severe depression in an ‘open label’ trial. Significantly, the study, led by researchers in the UK and China, identified a telltale signature of brain activity that predicted how well individual patients responded to the treatment. This could be used in future to target the treatment at those patients most likely to benefit. Major ...

The background: Multicellular organisms (animals, plants, human) all have the ability to methylate the cytosine © base in their DNA. This process, a type of epigenetic modification, plays an important role in conditions such as cancer and processes such as aging. The findings: In this new paper, the researchers discovered that in more ‘primitive’ unicellular organisms, both the adenine and the cytosine bases are methylated. This would suggest that in some ways, these unicellular organisms are more complex than their multicellular peers. The team also found that methylation of the adenine ...

Antimicrobial resistance (AMR) is a growing health challenge, reducing the effectiveness of life-saving treatments and increasing the risk of complications from routine medical procedures.  To support global AMR research, EMBL’s European Bioinformatics Institute (EMBL-EBI) has launched the AMR portal, a central hub that connects bacterial genomes, resistance phenotypes, and functional annotations, all in one place.  The first release of the AMR portal is based upon a dataset from Imperial College London obtained from the Comprehensive Assessment of Bacterial-Based Antimicrobial resistance prediction ...

The weather patterns that produced some of Europe’s most extreme heat waves over the past three decades could prove far more lethal if they strike in today’s hotter climate, pushing weekly deaths toward levels seen during the COVID pandemic, according to a November 18 study in Nature Climate Change. “We showed that if these same weather systems were to occur after we’ve trapped a lot more heat in the atmosphere with greenhouse gases, the intensity of the heat waves gets stronger and ...

 Feeling thirsty? Why not tap into the air? Even in desert conditions, there exists some level of humidity that, with the right material, can be soaked up and squeezed out to produce clean drinking water. In recent years, scientists have developed a host of promising sponge-like materials for this “atmospheric water harvesting.”  But recovering the water from these materials usually requires heat — and time. Existing designs rely on heat from the sun to evaporate water from the materials and condense it into droplets. But this step can take hours or even days.   Now, MIT engineers ...

Large language models can help improve questionnaires used to diagnose mental illness by optimizing symptom generalizability and reducing redundancy. They can even contribute to new conceptualizations of mental disorders. That is the result of an international study led by Professor Dr Joseph Kambeitz and Professor Dr Kai Vogeley from the University of Cologne’s Faculty of Medicine and University Hospital Cologne. The results of the study ‘The empirical structure of psychopathology is represented in large language models’ have been published in the journal Nature Mental Health. To ...

The Notre-Dame Cathedral in Lausanne was built between 1170 and 1235 and is the largest Gothic church in Switzerland. Over time, this imposing building has been altered, extended and restored on multiple occasions. The nearly 80-metre-tall lantern tower, for example, has undergone several redesigns over the years, the most recent of which took place at the end of the 19th century during an extensive restoration. The stone used to build this cathedral, and many other monuments in the Swiss plateau, is particularly susceptible to a variety of degradation mechanisms, all of which are enabled by the presence of water (such ...

Researchers at the University of Tokyo developed an experimental method to induce a strong physiological response linked to psychological pressure by making participants aim for a streak of success in a task. Their findings suggest this approach reproduces pressurelike conditions in a laboratory setting more effectively than traditional methods, affording easier access to the study of this state. That in turn could open up research into how pressure influences human performance in physical and intellectual tasks. Whether in an exam hall or on the field, to “crack” under pressure is a common trope. But what’s the reality behind this idea? It’s easy to assume ...

Children have 20 milk teeth, 10 in each jaw. This set of teeth is important for chewing and speaking, and helps to keep space open for the subsequent set of 32 permanent teeth. Milk teeth begin to develop in the womb around the sixth week of gestation, and gradually come out ('erupt') between six months and three years after birth. However, there is considerable variation in this timing, due to genetics, geography, and an infant's overall health and nutritional status. Now, researchers from the US have shown for the first time that another factor can speed up the timing of teeth eruption: maternal ...

Nigella sativa (black cumin), the spice that boosts the flavor of curries like korma and paneer also has another use: its seeds have long been used as a medicinal plant in traditional medicine for their antioxidant and anti-inflammatory effects. Now, a clinical trial led by Osaka Metropolitan University suggests that they also have anti-obesity benefits. To investigate these effects, a team led by Associate Professor Akiko Kojima-Yuasa of the Graduate School of Human Life and Ecology used cellular experiments and human clinical trials. In ...

A research team in South Korea has developed a novel gasket technology that enhances both the safety and efficiency of polymer electrolyte membrane fuel cells (PEMFCs) and water electrolyzers (PEMWEs, AEMWEs)—core devices for hydrogen production and utilization—by simultaneously improving mechanical strength and gas-tight sealing. Dr. Keun-Hwan Oh and his colleagues at the Korea Research Institute of Chemical Technology (KRICT) have successfully applied functionalized two-dimensional boron nitride nanoflakes (BNNFs) to silicone and ethylene-propylene-diene monomer (EPDM)-based sealing gaskets. The newly developed nanocomposite gasket demonstrates excellent ...

WASHINGTON, D.C. — [November 18, 2025] —Nearly half of U.S. adults (47%) are worried they won’t be able to afford necessary healthcare in the coming year, the highest level of concern recorded since West Health and Gallup began tracking in 2021. The share of Americans reporting that they or someone in their household were not able to pay for prescription medications in the past three months has reached a record high of 20%, or one in five Americans. These trends are clear: millions of Americans are facing growing challenges ...

Vaccination rates are falling in many communities due to widespread misinformation and previously eliminated or controlled illnesses like measles are surging across the United States and Canada.   Researchers at the University of Waterloo have developed a new approach that could help public health officials predict where outbreaks might occur. By analyzing social media posts, the method identifies early signs of increasing vaccine skepticism — a warning signal that could emerge before any disease begins to spread.  “In nature, we have contagious ...

The rapid development of humanoid robots necessitates environmental perception for autonomous locomotion and dexterous manipulation. As one of the most fundamental perceptual modalities, tactile sensing provides critical physical feedback during contact-rich interactions. However, this sensing capability introduces a fundamental trade-off between compliance in physical interactions and high-fidelity response to mechanical stimuli.   The biomechanical intelligence of human fingertips offers a compelling paradigm ...
