A three-year UT Dallas study tracking nearly 4,000 adults to age 94 says brain function can climb at any age. The biology is plausible. The catch is that the people measuring the gain are the same people patenting the yardstick.
Brain & AgingA new Cell paper finds Alzheimer's brains are riddled with the same mutations that drive blood cancers, in the immune cells that are supposed to be protecting neurons.
Brain & AgingAn OIST team caught the mouse brain firing acetylcholine the moment an expected reward failed to land. That surge is what lets the animal switch strategy. Close to half of community-dwelling older adults are on drugs that block the same receptors.
Brain & Aging54,804 Danes followed for a quarter-century: less dementia from vegetable nitrate, more from drinking water. The risk signal shows up at roughly one-ninth of what the US EPA still permits.
Brain & AgingAn ETH Zurich team spent nearly twenty years tracing why Alzheimer's nerve cells run out of energy, and the answer points to a protein the amyloid-clearing drugs never touched.
Brain & AgingHarvard used MERFISH to image roughly 1,100 odorant receptors across the mouse nose at once and found tidy stripes, not chaos. The clinical stakes for smell loss just got harder to wave off.
