PHILADELPHIA— Type 1 diabetes (T1D) impacts nearly two million Americans, and by the time most people learn they have it, most of the body's insulin-producing cells are destroyed. Now, pinpointing a hidden group of immune “attack” cells in the pancreatic lymph nodes that appear earlier in the disease could offer the first real chance to detect – and even stop- T1D, according to new research from the Perelman School of Medicine at the University of Pennsylvania detailed in Science Immunology. “For the first time, this research has caught the attack cells in the act, while the disease is still unfolding; we’re not just seeing the wreckage after the ...

BUFFALO, N.Y. – When designing membranes that separate industrial gases, scientists often incorporate structures that attract the gas they want to obtain. This attraction can enhances the membrane’s permeability, and help isolate the desired gas more efficiently. A study today in Science Advances shows sometimes the opposite can occur – the chemically enhanced membrane can bind too strongly to the intended gas, thus slowing the membrane’s permeability and reducing the separation efficiency. “It’s very counterintuitive, and it challenges traditional thinking in gas separation science,” says the study’s corresponding author Haiqing Lin, ...

Biomedical researchers at Texas A&M University may have discovered a way to stop or even reverse the decline of cellular energy production — a finding that could have revolutionary effects across medicine. Dr. Akhilesh K. Gaharwar and Ph.D. student John Soukar, along with their fellow researchers from the Department of Biomedical Engineering, have developed a new method to give damaged cells new mitochondria, returning energy output to its previous levels and dramatically increasing cell health. Mitochondrial decline is linked to aging, heart disease and neurodegenerative disorders. Enhancing the ...

MINNEAPOLIS/ST. PAUL (11/21/2025) — University of Minnesota Medical School researchers have shown that reducing chronic inflammation can significantly protect against age-related macular degeneration (AMD)-like pathology in preclinical models. The findings were recently published in Cell Death and Disease. AMD is the leading cause of vision loss and blindness for Americans aged 65 years and older, according to the Centers for Disease Control and Prevention. While most current AMD therapies treat only late-stage ...

Whether you’re a home gardener or an industrial farmer, you might be familiar with mulching films — plastic sheets laid over the soil to protect seedlings and promote crop growth. But like many other plastic materials, these films can release damaging microplastics and don’t have any insect-repelling power. So, a team reporting in ACS Agricultural Science & Technology has developed an alternative biodegradable mulching film that also naturally repels pests using citronella oil. “This research shows that it is possible to protect crops using biodegradable ...

Despite recommendations for posttreatment surveillance in lung cancer patients, there is wide variability in the follow-up care that lung cancer patients receive.

Lightweight components are generally designed with computer-based methods before being manufactured. There are various common methodologies. Because they use different physical and mathematical descriptions, however, direct comparisons are difficult. Moreover, the highly complex computation methods limit them to low spatial resolutions. With their Stress-Guided Lightweight 3D Designs (SGLDBench) benchmark, the researchers have succeeded in overcoming these serious obstacles. SGLDBench standardizes lightweight design methods SGLDBench permits six reference strategies such as classical topology optimization, ...

Improving diet and increasing physical activity levels together may be more effective at preventing weight gain – particularly harmful fat inside the abdomen – than just changing one of these behaviours, new research from the University of Cambridge suggests. An analysis of changes in physical activity and diet quality in UK adults found that while improved diet quality and increased physical activity were each independently associated with lower increases in body fat, the greatest benefits were achieved by combining both.   Body fat is stored in different locations, some of which are more harmful than others. Subcutaneous ...

At the cellular level, the mechanics of how muscle tissue repair occurs gets complicated. There are significant differences between, say, tearing a muscle in a sports injury versus muscle tissue wasting away from diseases like muscular dystrophy. Now, a new study led by experts at Cincinnati Children’s reports finding a shared—and unexpected—mechanism that may help improve healing across several types of muscle injury. The eye-opening study was published online Nov. 21, 2025, in Current Biology. The study was led by first author Gyanesh Tripathi, PhD, and corresponding author Michael Jankowski, PhD, who ...

New York, NY [November 21, 2025]—Researchers at the Icahn School of Medicine at Mount Sinai and collaborators have created the most comprehensive map to date showing how antibodies attach to the SARS-CoV-2 virus, which causes COVID-19, and how viral mutations weaken that attachment. The findings, published in the November 21 online issue of Cell Systems, a Cell Press journal, explain why variants like Omicron can evade immune defenses and suggest new strategies for building longer-lasting ...

In the search for a way to measure different forms of a condition called sensory processing disorder, neuroscientists are using imaging to see how young brains process sensory stimulation. Now, investigators at UC San Francisco have found a distinctive pattern for overwhelm in some children who are overly sensitive to sound, touch, and visual information. The finding could one day help clinicians refine treatments for kids who have strong emotional and behavioral reactions, such as tantrums, to their sensory environment. Sensory processing disorder affects how the brain understands and responds ...

The American Meteorological Society continuously publishes research on climate, weather, and water in its 12 journals. Many of these articles are available for early online access–they are peer-reviewed, but not yet in their final published form. Below are some recent examples of online and early-online research. JOURNAL ARTICLES Remote Effects of Urbanization on Temperatures in Adjacent Cities: A Case Study in Utah Journal of Applied Meteorology and Climatology Adjacent urban areas appear to exacerbate each other’s ...

Chemotherapy activates a stress sensor in immune cells, triggering inflammation and nerve damage, which may help explain why many cancer patients experience debilitating pain as a side effect, according to a new study by Weill Cornell Medicine and Wake Forest University School of Medicine researchers. Up to half of all patients receiving chemotherapy experience chemotherapy-induced peripheral neuropathy (CIPN), which causes tingling, numbness and pain in the hands and feet. Since there are limited options to address ...

When conditions get too dry, Madagascar hissing cockroaches like to "cuddle". Under certain conditions, the large insects gather in groups, with many participants in physical contact with one another. According to recent research from Binghamton University’s Biological Sciences program, this strategy may prevent the cockroaches from drying out. The new study, “Plastic Behavioral Responses to Ambient Relative Humidity Influence Aggregation in a Large Gregarious Insect”, recently appeared in the journal Ethology, and was co-authored by Binghamton University Assistant ...

Across the Rio Grande–Bravo basin, which runs from Colorado to Mexico, water stress has been building for years. Reservoirs that once relied on steady snowmelt are now noticeably lower. Aquifers that supported farming communities for generations continue to decline, dropping faster than they can recharge. In some stretches, the river, which runs nearly 3,000 kilometers, disappears into dry sand before reaching its endpoint. Despite this growing strain, a full, basin-wide picture of how the river’s water is used and how much is being lost didn’t exist. People could see the symptoms, but ...

With winter approaching and people spending more time indoors, the quality of the air they breathe becomes increasingly important. Especially during cold and flu season. Researchers at UBC Okanagan are exploring an air-cleaning device that can remove airborne pathogens, offering a powerful new tool for reducing the spread of respiratory diseases in enclosed spaces. The traditional approach to alleviating transmission of infectious diseases involves improving a building’s ventilation system to regulate large-scale airflow, explains study co-author Dr. Sunny Li, professor in the School of Engineering. Personalized ventilation systems ...

Alzheimer’s disease (AD), a progressive neurodegenerative disorder, is one of the leading causes of dementia worldwide, and currently has no definitive cure. Although antibody-based therapies that target amyloid β (Aβ) have recently been developed, their clinical effectiveness remains limited. These treatments can be costly and cause immune-related side effects, highlighting the need for safer, affordable, and widely accessible approaches that can slow the progression of AD. In a new study, made available online on October 30, 2025, in Neurochemistry International, researchers from Kindai ...

A team of researchers at IOCB Prague headed by Dr. Tomáš Slanina has developed a new method for labeling molecules with fluorescent dyes that surpasses existing approaches in both precision and stability. The new fluorescent label remains covalently bonded to its target molecule and does not fall apart even under demanding conditions inside living cells. This allows scientists to track labeled molecules over long periods with high reliability – an advantage for research in biology, chemistry, and medicine. The study was published in Angewandte Chemie International Edition. ...

Researchers at Baylor College of Medicine have discovered a natural mechanism that clears existing amyloid plaques in the brains of mouse models of Alzheimer’s disease and preserves cognitive function. The mechanism involves recruiting brain cells known as astrocytes, star shaped cells in the brain, to remove the toxic amyloid plaques that build up in many Alzheimer’s disease brains. Increasing the production of Sox9, a key protein that regulates astrocyte functions during aging, triggered ...

PHILADELPHIA – A pioneering preclinical study has shown that CAR T cell therapy—a personalized form of immunotherapy used in cancer treatment—could be a highly effective tool against atherosclerosis, the condition where a build-up of plaque in the arteries reduces blood flow, leading to heart attacks and strokes. In tests in mice, the experimental CAR T cells blocked inflammation in arteries, preventing more than two-thirds of the plaque buildup seen in untreated controls. The research, led by scientists in the Perelman School of Medicine at the University of Pennsylvania, was published today in Circulation. “Our ...

The explosiveness of a volcanic eruption depends on how many gas bubbles form in the magma – and when. Until now, it was thought that gas bubbles were formed primarily when the ambient pressure dropped while the magma was rising. Gases that were dissolved in the magma in lower strata – due to the higher pressure – escape when the pressure drops and form bubbles. The more bubbles there are in the magma, the lighter it becomes and the faster it rises. This can cause the magma to tear apart, leading to an explosive eruption.  This process can be likened to a bottle of champagne: while the bottle is closed and therefore pressurised, the carbon dioxide remains ...

In research, induced pluripotent stem (iPS) cells are derived from skin, urine, or blood samples and developed into other cells, like heart tissue, that researchers want to study. Because of the similarities between certain dog and human diseases, canine iPS cells have potential uses  in regenerative medicine and drug discovery.　 Research on iPS cells is challenging because the cells are extremely sensitive to culture conditions. Before they are developed into other cells, iPS cells are in an undifferentiated state. At this stage, the cells are grown in a culture medium that provides the essential nutrients, growth factors, and signaling molecules that they ...
