A 37-year soil experiment revealed a hidden climate threat
The world's longest-running soil warming experiment has revealed an unexpected climate concern. After nearly four decades, researchers found that warming can cause microbes to break down stable soil carbon that scientists once believed was largely protected. That releases extra carbon dioxide into the atmosphere, potentially accelerating global warming.

Popular weight-loss drugs Ozempic and Wegovy may slow biological aging
Researchers found that semaglutide, the active ingredient in Ozempic and Wegovy, slowed biological aging markers in adults with HIV, marking the first clinical evidence that the drug may influence human aging. Although the findings are encouraging, scientists say larger studies are needed before concluding that the medication can help people age more slowly.

This dinosaur fossil captures the final moments of a T. rex attack
A fossilized Edmontosaurus skull with a Tyrannosaurus tooth still embedded in its face has given scientists rare evidence of a dramatic predator-prey encounter. The discovery suggests the giant carnivore delivered an incredibly powerful face-to-face bite, offering new clues about how Tyrannosaurus hunted.

Scientists discover why peach fuzz can suddenly make you itch
A newly discovered network of fine hairs and specialized nerve cells appears to form a dedicated system for sensing mechanical itch, offering fresh insight into why chronic itching occurs. Because humans show signs of having the same pathway, the research could pave the way for more effective treatments for conditions such as eczema.

New dark matter theory could solve multiple cosmic mysteries at once
Dark matter may be far more complicated than scientists once believed. A new study suggests it could consist of at least two different kinds of particles that slowly separate over time, with heavier particles sinking toward the centers of galaxies and lighter ones drifting outward. This simple idea could explain several puzzling cosmic observations that have frustrated astronomers for years, from unusually diffuse dwarf galaxies to surprisingly dense dark matter clumps that bend light through gravitational lensing.

Yale scientists found a hidden network inside the eye
Researchers have discovered that the retina uses an unexpected communication network that lets separate visual pathways cooperate instead of working alone. A newly identified "commander" cell appears to coordinate this system, helping the eye detect faint details that might otherwise be missed.

Exercise doesn't just strengthen the heart. It rewires it
Exercise doesn't just make the heart stronger. It also rewires the nerves that regulate it, a discovery that could pave the way for more personalized treatments for common heart conditions such as arrhythmias and angina.
