(PhysOrg.com) -- A new study has discovered that animal cells communicate electrically with each other via tunneling nanotubes (TNTs). The membrane tubes contain a protein called F-actin and connect cells over long distances ...
The eyes are marvelous instruments for converting outside reality into images lodged inside our brains. A new study of the retina, the light-sensitive region at the back of the eye, solves a mystery as to why the images we ...
