Biochemists trap and visualize an enzyme as it becomes active

How do you capture a cellular process that transpires in the blink of an eye? Biochemists at MIT have devised a way to trap and visualize a vital enzyme at the moment it becomes active—informing drug development and revealing ...

Octopuses have two alternating sleep states, study shows

Octopuses are known to sleep and to change color while they do it. Now, a study publishing March 25 in the journal iScience finds that these color changes are characteristic of two major alternating sleep states: an "active ...

Brain receptor pulls open electrical gate like a puppet master
