Insects are essential for ecosystems, but mounting evidence suggests many populations are collapsing under modern pressures. A new study used cutting-edge genomic techniques on museum specimens to track centuries of ant biodiversity across Fiji. The results reveal that nearly 80% of native ants are in decline, with losses intensifying in the past few hundred years as human activities expanded. Read more ›

Scientists have uncovered how exercise suppresses appetite through a surprising molecular pathway. A compound called Lac-Phe, produced during intense workouts, directly quiets hunger neurons in the brain while boosting appetite-suppressing ones, causing mice to eat less without side effects. This discovery reveals a natural mechanism linking physical activity and reduced hunger, paving the way for new obesity treatments. Read more ›

New research reveals lymphoma can directly accelerate aging in the immune system and vital organs, independent of treatments like chemotherapy. The changes, sometimes reversible, highlight a hidden dimension of cancer—and possible new paths for intervention. Read more ›

Despite strong evidence that salt substitutes can safely lower sodium intake and reduce high blood pressure, very few Americans use them. A new analysis of nearly 20 years of national health data found that usage peaked at just over 5% and then declined, even among those with hypertension. Researchers say this represents a major missed opportunity to improve heart health, especially since salt substitutes are inexpensive and effective. Read more ›

For decades, scientists have puzzled over why smoking makes Crohn’s disease worse but seems to protect people from ulcerative colitis. Now, researchers at RIKEN have discovered that smoking creates metabolites like hydroquinone that allow mouth bacteria—especially Streptococcus mitis—to settle in the gut. These bacteria spark an immune response that reduces inflammation in colitis but worsens Crohn’s. The findings open the door to new therapies using probiotics or targeted compounds that...

From the wreck of the royal Danish-Norwegian flagship Gribshunden, archaeologists have uncovered a rare glimpse into the naval power of the late Middle Ages. This warship, lost in 1495, carried an arsenal of small guns designed for close-range combat, symbolizing the technological leap that allowed European nations to dominate the seas. More than just a vessel, it served as King Hans’ floating castle, projecting both diplomatic influence and military might. Read more ›

Egg-eating worms living on Chesapeake Bay blue crabs may hold the key to smarter fishery management. Once thought to be a threat, these parasites actually serve as natural biomarkers that reveal when and how often female crabs reproduce. Researchers found the worms are surprisingly resilient to varying salinity levels, meaning they can track crab spawning across the Bay. Read more ›

Mayo Clinic scientists uncovered how excessive drinking triggers fatty liver disease by disrupting the enzyme VCP, which normally prevents harmful protein buildup on fat droplets in the liver. Alcohol blocks this protective process, allowing fat to accumulate and damage liver cells. Read more ›

Alcohol-associated liver disease is becoming a massive health and economic burden, but researchers at UC San Diego may have uncovered a new way forward. They discovered that chronic alcohol use blocks a crucial protein that normally helps keep gut bacteria from leaking into the liver, worsening damage. Restoring this protein’s function, using drugs already in development, could not only reduce liver disease but also have implications for treating alcohol addiction... Read more ›

Wildfires are no longer a seasonal nuisance but a deadly, nationwide health crisis. Fueled by climate change, smoke is spreading farther and lingering longer, with new research warning of tens of thousands of additional deaths annually by mid-century. The health costs alone could surpass all other climate damages combined, revealing wildfire smoke as one of the most underestimated threats of our warming world. Read more ›

Microplastics have been detected in human blood, brain tissue, and even bones, where they may weaken skeletal structure and accelerate cell aging. Recent studies suggest that these particles could worsen metabolic bone diseases like osteoporosis, a risk that’s especially concerning as fractures are projected to rise sharply in the coming decades.

A sweeping investigation has revealed widespread fraud in mathematics publishing, where commercial metrics and rankings have incentivized the mass production of meaningless or flawed papers. The study highlights shocking distortions—such as a university without a math department ranked as having the most top mathematicians—and the explosion of megajournals willing to publish anything for a fee.

What started as a frustrating kitchen challenge turned into award-winning science: Fabrizio Olmeda and his colleagues scientifically decoded the secret of creamy cacio e pepe and earned the Ig Nobel Prize. Their research showed how starch can stabilize Pecorino into a smooth sauce, turning a culinary mystery into physics-driven perfection. Read more ›

MIT scientists have unraveled the hidden energy balance of earthquakes by recreating them in the lab. Their findings show that while only a sliver of energy goes into the shaking we feel on the surface, the overwhelming majority is released as heat—sometimes hot enough to melt surrounding rock in an instant.

A new study challenges the dream of water-rich “Hycean” planets like K2-18b, suggesting that most sub-Neptunes lose their water deep into their interiors during formation. Instead of vast oceans, these worlds likely retain only a few percent of water at the surface. Read more ›

Scientists at Rutgers and collaborators have traced the invisible dark matter scaffolding of the universe using over 100,000 Lyman-alpha emitting galaxies. By studying how these galaxies clustered across three eras shortly after the Big Bang, they mapped dark matter concentrations, uncovering cosmic “fingerprints” that reveal how galaxies grow and evolve.

Astronomers have long relied on supercomputers to simulate the immense structure of the Universe, but a new tool called Effort.jl is changing that. By mimicking the behavior of complex cosmological models, this emulator delivers results with the same accuracy — and sometimes even finer detail — in just minutes on a standard laptop. The breakthrough combines neural networks with clever use of physical knowledge, cutting computation time dramatically while preserving... Read more ›

Plastic particles from everyday items like Styrofoam cups and take-out containers are finding their way into the brain, where they may trigger Alzheimer’s-like symptoms. New research shows that mice carrying the Alzheimer’s-linked APOE4 gene who consumed microplastics exhibited sex-dependent cognitive decline, mirroring the differences seen in human patients.

Scientists at Michigan State University have discovered how to use ultrafast lasers to wiggle atoms in exotic materials, temporarily altering their electronic behavior. By combining cutting-edge microscopes with quantum simulations, they created a nanoscale switch that could revolutionize smartphones, laptops, and even future quantum computers. Read more ›
