Medical Xpress / Scientists find a mechanism showing how exercise protects the brain

Researchers at UC San Francisco have discovered a mechanism that could explain how exercise improves cognition by shoring up the brain's protective barrier. With age, the network of blood vessels—called the blood–brain ...

Phys.org / Nanoengineers realize an on-chip excitonic hyperlens

When light passes through materials, it typically changes direction and bends in predictable ways. This change in direction, known as refraction, is caused by a change in the speed of light as it enters a new medium. In some ...
