New research may upend ideas about how proteins travel out of E. Coli cells, which could help in the treatment of disease.

Studying E. coli at neutral pH in the lab might not give us a full sense of their powers against antibiotics.

Probiotics adapt to the gut, research finds. "...what you put in your body is not necessarily what's going to be there even a couple hours later."

A new microscope is giving scientists a closer look at cell behavior. What they find could one day help create targeted drugs that have fewer side effects.
