Scientists just found a protein that reverses brain aging
Aging is particularly harsh on the hippocampus -- the brain region responsible for learning and memory. Now, researchers at UC San Francisco have identified a protein that's at the center of this decline. They looked at how the genes and proteins in the hippocampus changed over time in mice and found just one that differed between old and young animals. It's called FTL1. Old mice had more FTL1, as well as fewer connections between brain cells in the hippocampus and diminished cognitive abilit
