Researchers reviewing nearly 300 top-tier ADHD drug trials found that half skipped the rigorous, expert-led evaluations needed to rule out other conditions like depression or schizophrenia. With diagnoses often made by unqualified staff--or even by . ...

A sweeping review of more than a century's research upends the popular notion that left-handers are naturally more creative. Cornell psychologist Daniel Casasanto's team sifted nearly a thousand studies, ultimately finding no consistent advantage for ...

Scientists have achieved an unprecedented look into how the human immune system attacks a transplanted pig kidney, using spatial molecular imaging to map immune activity down to the cellular level. They discovered early signs of rejection within 10 . ...

Scientists have discovered a stealthy mechanism that cytomegalovirus (CMV)--the leading infectious cause of birth defects in the U.S.--uses to infiltrate blood vessel cells while evading immune detection. The virus forms a hidden protein complex that ...

Scientists have uncovered a surprising sugar-related mechanism inside brain cells that could transform how we fight Alzheimer's and other dementias. It turns out neurons don't just store sugar for fuel--they reroute it to power antioxidant defenses, ...

An AI system called iSeg is reshaping radiation oncology by automatically outlining lung tumors in 3D as they shift with each breath. Trained on scans from nine hospitals, the tool matched expert clinicians, flagged cancer zones some missed, and ...

Leprosy's tale stretches from 5,000-year-old skeletons in Eurasia to a startling 4,000-year-old case in Chile, revealing that the rare strain Mycobacterium lepromatosis haunted the Americas millennia before Europeans arrived. Armed with cutting-edge ...

Researchers at UT Arlington have discovered a key enzyme, IDO1, that when blocked, helps immune cells regain their ability to properly process cholesterol--something that breaks down during inflammation. This breakthrough could offer a powerful new . ...

Smoke from wildfires and structural fires doesn t just irritate lungs it actually changes your immune system. Harvard scientists found that even healthy people exposed to smoke showed signs of immune system activation, genetic changes tied to ...

Deleting a gene called PTEN in certain brain cells disrupts the brain's fear circuitry and triggers anxiety-like behavior in mice -- key traits seen in autism. Researchers mapped how this genetic tweak throws off the brain's delicate balance of ...
