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 ...

Researchers found that drinking guava juice may significantly improve anemia by helping the body absorb iron more efficiently. In a review of 17 studies, women and teenage girls who consumed guava juice -- especially with iron supplements -- ...

New research suggests Earth's climate can swing wildly on surprisingly short timescales -- even during hot, ice-free greenhouse periods. By studying ancient sediments from the Late Cretaceous, scientists uncovered repeating climate shifts tied to ...

Humanity may already be living far beyond what Earth can sustainably support, according to a sweeping new study analyzing more than 200 years of population and environmental data. Researchers found that while population growth once fueled innovation ...

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 ...

Vitamin B12 has long been seen as a health hero, helping the body make red blood cells, repair DNA, and keep nerves functioning properly. But scientists are discovering that the story may be more complicated than simply "more is better." While too .. ...

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 .. ...

A new AI-powered chip from UC Davis can analyze light and chemicals using a device tiny enough to fit almost anywhere. By combining smart silicon sensors with machine learning, it achieves lab-style spectral analysis without the bulky equipment.
