Cell’s ‘Garbage Disposal’ May Have Another Role: Helping Neurons Near Skin Sense the Environment
The typical job of the proteasome, the garbage disposal of the cell, is to grind down proteins into smaller bits and recycle some of those bits and parts. That’s still the case, for the most part, but, Johns Hopkins Medicine researchers, studying nerve cells grown in the lab and mice, say that the proteasome’s role may go well beyond that.

A new study provides novel insight into the benefits of exercise, which should motivate adults to keep moving throughout their lifetime, especially during middle age. Long-term exercise profoundly benefits the aging brain and may prevent aging-related memory function decline by increasing the survival and modifying the network of the adult-born neurons born during early adulthood, and thereby facilitating their participation in cognitive processes.
