Foetal brains begin to fold around the midpoint of the third trimester, but little is known about the actual process. A new model, in which a hunk of gel was made to swell in a liquid bath, shows how it happens in surprisingly accurate detail.
Researchers at Itmo University in Russia have found a way to fold mutilated proteins back into the right shape. Afterwards, the proteins work better than they did before. They call it the “Phoenix Effect”: an exhausted protein is ripped apart by heat, only to rise again better than before.
