Scientists have identified a brain protein that may help Alzheimer’s spread, revealing a potential new target for slowing the disease’s progression. Alzheimer’s disease is closely linked to the accumulation of a toxic form of the protein Tau inside the brain. As Tau damage reaches additional brain regions, more neurons are harmed, symptoms intensify, and the [...]

New research suggests that low oxygen levels may help alleviate disease caused by defects in mitochondrial quality control. Oxygen is essential for people—and most other organisms—but more is not always better. When oxygen accumulates beyond what cells can safely use, it can become toxic and contribute to serious health problems. In the brain, excess oxygen [...]

A reverse prediction test suggests that supposedly brainlike AI models may rely on visual strategies the primate brain does not use. Artificial intelligence can sometimes predict how the brain responds when people recognize objects. But that resemblance may hide an important weakness: the internal workings of today’s vision models do not necessarily match the processes [...]
