A Salk Institute study found that a simple dietary amino acid, methionine, dramatically improved survival in mice facing severe infections and inflammatory conditions. Rather than directly targeting the immune system, methionine boosted kidney ...

A promising new study suggests rheumatoid arthritis may not be as inevitable as once thought for people at high risk. Researchers found that just one year of treatment with the immune-targeting drug abatacept delayed the onset of rheumatoid arthritis ...

A major mouse study found that some inherited traits are passed down through epigenetic changes that break the classic rules of genetics. Researchers discovered hundreds of cases where these chemical DNA marks behaved unexpectedly, including some ...

NASA's futuristic X-59 jet is about to face its biggest challenge yet: breaking the sound barrier for the first time. After a successful series of test flights that pushed the aircraft to near-supersonic speeds, engineers are preparing to fly it ...

A stunning spiral galaxy called Messier 88 is racing through the crowded Virgo Cluster on a journey that will dramatically reshape its future. At its heart lies a supermassive black hole about 100 million times the mass of the Sun, while its graceful ...

NASA's Roman Space Telescope could revolutionize the search for alien worlds by discovering around 100,000 exoplanets--far more than all previous missions combined. It will look deep into unexplored parts of the Milky Way, helping scientists compare ...

A long-overlooked organ may hold surprising clues to healthy aging and cancer survival. Researchers at Mass General Brigham used AI to analyze CT scans from tens of thousands of adults and found that people with healthier thymuses--a small immune ...

A world-famous conservation program that helped save Sweden's endangered wolverines is now struggling as funding stagnates and local trust erodes. Researchers say the decline offers a cautionary lesson: protecting wildlife requires long-term ...

A remarkable crystal called molybdenum oxychloride could help make futuristic technologies like smart contact lenses and ultrathin AR glasses a reality. Scientists have created the first detailed experimental map of its optical properties, revealing ...

Scientists at Scripps Research have uncovered a molecular "switch" that appears to fuel the damaging brain inflammation seen in Alzheimer's disease. They found that a protein called STING becomes chemically altered in a way that keeps the brain's ...
