One protein might be driving brain aging
Called FTL1. In aging mice, higher levels of this protein weakened connections between brain cells and caused memory decline. Reducing it reversed some of that.
Mice aren’t humans. But every time something like this shows up, it’s one more piece of the puzzle of why the brain degrades. The idea that aging might be modifiable rather than fixed is no longer fringe science.
