A new experimental drug is showing remarkable promise for children with Dravet syndrome, a severe genetic form of epilepsy. In clinical trials, the treatment zorevunersen cut seizures by as much as 91% while also improving quality of life for many patients. The therapy works by boosting the function of a key gene involved in nerve cell signaling. Encouraging results have led researchers to launch a larger Phase 3 trial.View the full article

Popular weight-loss drugs such as Ozempic, Wegovy, and Mounjaro may do more than help people shed pounds. New research suggests these GLP-1 medications could also help protect the heart after a heart attack by restoring blood flow in tiny blood vessels that often remain blocked even after doctors reopen a major artery.View the full article

Daily aspirin does not reliably prevent bowel cancer in people at average risk, according to a major new review. Any potential protective effect may take more than a decade to appear — if it appears at all — and the evidence for that benefit is weak. In contrast, the risk of serious bleeding begins right away, even with low-dose aspirin. Experts warn that prevention decisions should be individualized, not automatic.View the full article

Iron Age teeth from southern Italy have become time capsules, preserving intimate details of childhood and diet. Growth lines in the enamel reveal moments of early-life stress, while hardened plaque holds microscopic remains of cereals, legumes, and fermented foods. The findings suggest a community with diverse food resources and strong Mediterranean connections. Even a small sample offers a striking glimpse into how people lived, grew, and ate nearly three millennia ago.View the full article

Stiff knees and aching hips may seem like an inevitable part of aging, but experts say we’re getting osteoarthritis all wrong. Despite affecting nearly 600 million people worldwide — and potentially a billion by 2050 — the most powerful treatment isn’t surgery or medication. It’s exercise. Movement nourishes cartilage, strengthens muscles, reduces inflammation, and even reshapes the biological processes driving joint damage.View the full article

Scientists at the University of Tokyo have captured something never seen before: a frame-by-frame view of how electron spins flip inside an antiferromagnet, a material once thought to be magnetically “invisible.” By firing ultrafast electrical pulses into a thin layer of manganese–tin and tracking the response with precisely timed flashes of light, the team uncovered two distinct switching mechanisms. One relies on heat generated by strong currents, while the other flips spins directly with minimal heating — a far more efficient process.View the full article

A sweeping new study reveals that what’s on your plate may directly shape the pesticides circulating in your body. Researchers found that people who eat more fruits and vegetables known to carry higher pesticide residues—such as strawberries, spinach, and bell peppers—also have significantly higher levels of those chemicals in their urine. While produce remains a cornerstone of a healthy diet, the findings highlight how everyday food choices can drive real-world exposure to substances linked to cancer, hormone disruption, and developmental harm.View the full article

Northern wildfires may be more dangerous for the climate than they appear. Researchers found that fires in boreal forests can burn deep into peat soils, releasing ancient carbon stored for hundreds or thousands of years. These slow, smoldering fires often look small from space, causing climate models to underestimate their emissions.View the full article

Researchers have built the smallest OLED pixel ever made—just 300 nanometers across—without sacrificing brightness. By redesigning the pixel with a nano-sized optical antenna and a protective insulation layer, they prevented the short circuits that normally plague devices at this scale. The result is a stable, ultra-tiny light source that could allow full HD displays to fit on an area the size of a grain of sand.View the full article

Researchers at Kobe University have developed an AI system that can detect acromegaly, a rare hormone disorder, by analyzing photos of the back of the hand and a clenched fist. The disease often develops slowly and can take years to diagnose, even though untreated cases may shorten life expectancy.View the full article

Returning rescued slow lorises to the wild may sound like a conservation success, but a new study shows it can turn deadly. Researchers tracked nine released animals and found that only two survived, with most killed in territorial attacks by other lorises. Scientists say better planning is essential to ensure wildlife releases actually help endangered species.View the full article

A new study has uncovered why some brain cells are more resistant to Alzheimer’s damage than others. Researchers found a natural cleanup system that helps remove toxic tau protein before it can form harmful clumps. The study also shows that cellular stress can produce a dangerous tau fragment linked to Alzheimer’s. Strengthening the brain’s natural defenses could point the way to new treatments.View the full article

An international team combining two major neutrino experiments has uncovered stronger evidence that neutrinos and antimatter don’t behave as perfect mirror images. That subtle difference may hold the key to why the universe didn’t vanish in a flash of self-destruction after the Big Bang.View the full article

Japanese snow monkeys don’t just soak in hot springs to escape the winter chill — their steamy spa sessions may also be reshaping their invisible world. Researchers in Japan found that macaques who regularly bathe show subtle but intriguing differences in lice patterns and gut bacteria compared to those who stay dry. Surprisingly, sharing the hot pools didn’t increase their parasite load, challenging assumptions about disease risk.View the full article

Choosing the right method for multimodal AI—systems that combine text, images, and more—has long been trial and error. Emory physicists created a unifying mathematical framework that shows many AI techniques rely on the same core idea: compress data while preserving what’s most predictive. Their “control knob” approach helps researchers design better algorithms, use less data, and avoid wasted computing power. The team believes it could pave the way for more accurate, efficient, and environmentally friendly AI.View the full article

Scientists have uncovered a surprising new hero in the fight against one of the world’s deadliest fungal infections: albumin, the most abundant protein in human blood. In a major international study, researchers found that people who develop mucormycosis — a fast-moving and often fatal “black fungus” infection — have strikingly low levels of albumin, and that this deficiency strongly predicts death.View the full article

In Yellowstone’s wild chess match between wolves and cougars, it turns out the real power play is theft. After tracking nearly a decade of GPS data and thousands of kill sites, researchers found that wolves often muscle in on cougar kills—sometimes even killing the cats—but cougars never return the favor. Instead of fighting back, cougars adapt. As elk numbers dropped, they shifted toward hunting more deer, which they can eat quickly and in safer terrain, helping them dodge wolf encounters.View the full article

When a bone break is too severe to heal on its own, surgeons often rely on grafts or rigid metal implants — but both come with serious drawbacks. Now, researchers at ETH Zurich have created a jelly-like hydrogel that mimics the body’s natural healing process, offering a potentially game-changing alternative. Made of 97% water, this soft material can be laser-printed into intricate bone-like structures at record-breaking speeds, down to details thinner than a human hair.View the full article

Scientists have identified a crucial molecular switch that decides whether pancreatic cancer cells resist chemotherapy or respond to it. The key player, a gene called GATA6, keeps tumours in a more structured and treatable form—but it gets shut down by an overactive KRAS-driven pathway. When researchers blocked that pathway, GATA6 levels rebounded and cancer cells became more sensitive to chemo. The discovery could help turn some of the toughest pancreatic tumours into ones doctors can better control.View the full article

For decades, scientists have mapped attention, memory, language, and reasoning to separate brain networks — yet one big mystery remained: why does the mind feel like a single, unified system? Researchers at the University of Notre Dame now suggest that intelligence doesn’t live in one “smart” region of the brain at all. Instead, it emerges from how efficiently and flexibly the brain’s many networks communicate and coordinate with each other.View the full article

A famously resilient bacterium may be tough enough to survive one of the most violent events imaginable on Mars. In laboratory experiments designed to mimic the crushing shock of a massive asteroid impact, researchers squeezed Deinococcus radiodurans between steel plates and blasted it with pressures reaching 3 GPa (30,000 times atmospheric pressure). Even under these extreme conditions, a significant portion of the microbes survived.View the full article

Astronomers using the James Webb Space Telescope have spotted the most distant “jellyfish galaxy” ever seen — a cosmic oddity streaming long, tentacle-like trails of gas and newborn stars as it speeds through a dense galaxy cluster. The galaxy appears as it was 8.5 billion years ago, revealing that the early universe may have been far more violent than scientists expected.View the full article

Researchers at the University of Basel and the ETH in Zurich have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create adaptable electronic circuits with light.View the full article

Fusion energy may be one of the most promising clean power sources of the future—but only if scientists can precisely measure the extreme, fast-moving plasmas that make it possible. A new U.S. Department of Energy–sponsored report urges major investment in advanced diagnostic tools—the high-tech “sensors” that track plasma temperature, density, and behavior inside fusion systems. Bringing together 70 experts from universities, national labs, and private industry, the workshop identified seven priority areas ranging from burning plasma to full-scale pilot plants.View the full article
