These cells, which aren’t part of the immune system, unleash a detergent-like protein that dissolves chunks of the inner membranes of bacteria, killing the infiltrators, researchers report inContinue Reading

A method called optogenetics offers insights into memory, perception and addiction. Some big scientific discoveries aren’t actually discovered. They are borrowed. That’s what happened when scientists enlisted proteins from an unlikely lender: green algae. Cells of the algal species Chlamydomonas reinhardtii are decorated with proteins that can sense light. ThatContinue Reading
