A mysterious little blue octopus discovered nearly 6,000 feet beneath the waters of the Galápagos Islands has officially been identified as a brand-new species. About the size of a golf ball, the tiny creature stunned researchers during a deep-sea expedition…

USC researchers have identified potential new drug compounds that may reduce the brain inflammation linked to Alzheimer’s disease, especially in people with the high-risk APOE4 gene. The compounds target cPLA2, an enzyme that seems to fuel harmful inflammation…

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 from…

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” appearance…

A new study suggests melatonin supplements may help night shift workers boost their body's DNA repair processes, potentially offsetting some of the damage linked to working overnight. The findings are early but raise the possibility of a simple strategy…

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 immune system…

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 filtration…

A massive study of more than 600,000 U.S. veterans suggests that popular GLP-1 drugs such as semaglutide may do far more than help with diabetes and weight loss—they could also fight addiction itself. Researchers found that people taking these medications…

Octopuses may be even smarter than we thought. Researchers at Dartmouth found that octopuses can learn to use mirrors to locate food hidden behind them—a skill previously seen only in vertebrates like mammals and birds. After training, the animals correctly…

Scientists have uncovered a key brain signal that helps us break old habits and adapt when circumstances suddenly change. By watching mice navigate a virtual maze, researchers found that disappointment—when an expected reward failed to appear—triggered a…

A potentially dangerous tapeworm linked to severe, cancer-like disease has now been found in the Pacific Northwest, marking its first detection in wild animals along the U.S. West Coast. Researchers discovered the parasite, Echinococcus multilocularis, in…
