  • Scientists just mapped how the body rejects pig organs—and how to stop it
    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 days and pinpointed key immune players—like macrophages—driving the response. Even more exciting: when targeted therapies were applied, […]
  • This virus infects millions—and we just discovered its secret weapon
    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 acts like a molecular “backdoor,” allowing it to bypass the immune system’s defenses. This newly identified pathway may explain why […]
  • Scientists just found a sugar switch that protects your brain from Alzheimer's
    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, but only if an enzyme called GlyP is active. When this sugar-clearing system is blocked, toxic tau protein builds […]
  • This AI tracks lung tumors as you breathe — and it might save lives
    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 could speed up treatment planning while reducing deadly oversights.
  • Ancient DNA reveals leprosy hit the Americas long before colonization
    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 ancient-DNA sleuthing, scientists have pieced together remarkably well-preserved genomes that challenge the idea of leprosy as purely a colonial import and hint that […]
  • Scientists discover ‘off switch’ enzyme that could stop heart disease and diabetes
    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 way to fight heart disease, diabetes, cancer, and more. By "turning off" this enzyme, the team restored cholesterol absorption in […]
