Leafcutter ants live in highly organized colonies where every ant has a job, and now researchers can flip those jobs like a switch. By manipulating just two neuropeptides, scientists can turn defenders into nurses or gardeners into leaf harvesters. . ...

Lichen from the Mojave Desert has stunned scientists by surviving months of lethal UVC radiation, suggesting life could exist on distant planets orbiting volatile stars. The secret? A microscopic "sunscreen" layer that protects their vital cells- ...

Wildfires don't just leave behind scorched earth--they leave a toxic legacy in Western rivers that can linger for nearly a decade. A sweeping new study analyzed over 100,000 water samples from more than 500 U.S. watersheds and revealed that ...

Major depressive disorder affects hundreds of millions worldwide, but a key to understanding its origins may lie in the brain's immune system. New findings spotlight astrocytes--previously overshadowed by microglia--as major players in ...

Over 300 million years ago, Earth experienced powerful bursts of carbon dioxide from natural sources--like massive volcanic eruptions--that triggered dramatic drops in ocean oxygen levels. These ancient "carbon burps" led to dangerous periods of ...

Scientists have uncovered a stealthy tactic used by the SARS-CoV-2 virus: one of its proteins can leap from infected cells to healthy ones, effectively tricking the immune system into attacking the body's own tissues.

Southern resident killer whales have been caught on drone video crafting kelp tools to groom one another--an unprecedented behavior among marine mammals. This suggests a deeper social and cultural complexity in these endangered whales than scientists ...

Two Ice Age wolf pups once thought to be early dogs have been identified as wild wolves, thanks to detailed DNA and chemical analysis. Surprisingly, their last meals included woolly rhinoceros meat--an unusually large prey item--hinting that ancient ...

Exploration for deep-sea minerals in the Clarion Clipperton Zone threatens to disrupt an unexpectedly rich ecosystem of whales and dolphins. New studies have detected endangered species in the area and warn that mining noise and sediment could ...

A groundbreaking wireless implant promises real-time, personalized pain relief using AI and ultrasound power no batteries, no wires, and no opioids. Designed by USC and UCLA engineers, it reads brain signals, adapts on the fly, and bends naturally .. ...
