When the body runs low on protein, the gut sends powerful signals to the brain that reshape cravings and push animals to seek essential amino acids instead of sugar. Researchers say this newly discovered gut-brain network could transform our ...

A sea slug smaller than a sesame seed has turned up in Taiwan's coastal waters -- and it's so tiny and unusual that scientists realized they had discovered a completely new species. Named Thecacera sesama after its black-and-yellow "sesame-like" ...

A giant planet nearly 700 light-years away has a bizarre daily weather cycle where mineral clouds appear every morning and vanish by nightfall. Using the James Webb Space Telescope, astronomers discovered that WASP-94A b's mornings are filled with .. ...

NASA's Fermi telescope has detected what may be the first confirmed gamma-ray signal from a superluminous supernova -- one of the most extreme explosions in the universe. Scientists believe the blast was powered by a rapidly spinning magnetar, an ...

Scientists uncovered evidence that human blood cells may trace their origins back to single-celled ancestors that lived 700 million years ago. By rebuilding the evolutionary family tree of blood cells, the team revealed how today's immune system grew ...

Scientists in Japan have created powerful new vitamin K-based compounds that may help the brain regenerate lost neurons -- a breakthrough that could one day change how diseases like Alzheimer's and Parkinson's are treated. By combining vitamin K with ...

Researchers at Texas A&M have developed a nasal spray that appears to reverse brain aging by calming inflammation and restoring the brain's energy systems. After just two doses, memory and cognitive function improved for months, raising hopes for ...

Scientists working at CERN's Large Hadron Collider may be seeing the strongest hints yet of physics beyond the Standard Model -- the decades-old theory that explains the fundamental particles and forces of the universe. By studying incredibly rare .. ...

Scientists have created a global "treasure map" for rare earth elements by uncovering where the strange volcanic rocks that contain them are most likely to form. By combining thousands of rock samples with seismic images of Earth's deep interior, the ...

When a queen wasp suddenly disappears, her colony doesn't calmly choose a successor -- it erupts into chaos. Researchers found that female wasps immediately begin battling for power, shattering the colony's social order in a frenzy of aggression. But ...
