Mice bred with tau pathology and Alzheimer’s genetics lost their brain-damaging immune response when researchers deleted a scarce class of dendritic cells that operates entirely in lymph nodes outside the brain.
A study of nearly 16,000 children finds that sensory over-responsivity tracks tightly with anxiety and autism, not ADHD, and traces to a weakened link between a memory network and the caudate nucleus.
A week of daily separations left adult mouse brain cells with their DNA packaging loosened, and of sixteen candidate enzymes only one had changed. Add that enzyme to unstressed pups and they grew up fragile. Take it away and stressed pups grew up steady.
Fuel cells run on platinum, and platinum is scarce and expensive. A new carbon material riddled with tiny channels stops the metal from clumping and wearing away, which could mean cheaper fuel cells that last long enough for trucks and data centers to rely on.
