Aging

New research makes a molecular connection between the brain and aging — and shows that overactive neurons can shorten life span.

While we sleep, one kind of slow brain wave helps to reinforce memories, but a competing wave weakens them.

The discovery that apparently dead cells can sometimes resurrect themselves has researchers exploring how far they can push the point of no return.

A unique neurological “functional fingerprint” allows scientists to explore the influence of genetics, environment and aging on brain connectivity.

Trash collectors in the cell moonlight at the controls of the genetic machinery.

Life was long thought to obey its own set of rules. But as simple systems show signs of lifelike behavior, scientists are arguing about whether this apparent complexity is all a consequence of thermodynamics.
