two-photon microscopy

A new protein may allow researchers to home in on individual neurons, determining their activity minute by minute.

In the 1990s, the development of this gentler and more precise microscopy method improved scientists’ ability to probe neurons’ activity and anatomy.

Studies in rodents are beginning to reveal how mammalian navigational sense works.

When influenza invades the mouse respiratory tract, neutrophils guide the subsequent T-cell attack on infected tissue, scientists show.
