Plants lack eyes and ears, but they can still see, hear, smell and respond to environmental cues and dangers. They do this with the aid of hundreds of membrane proteins that sense microbes or other stresses. Researchers now have created the first network map for 200 of these proteins. The map shows how a few…

The new protocol could be a step toward stem cell-based therapies to restore sensation in paralyzed people who have lost feeling in parts of their body. (1) We want to sense.…
