Here’s a rare way that an Alzheimer’s protein can spread
Amyloid-beta found in vials of growth hormone can move from brain to brain, a mouse study shows.
- Animals
50 years ago, armadillos hinted that DNA wasn’t destiny
Nine-banded armadillos have identical quadruplets. But the youngsters aren’t identical enough, and scientists 50 years ago could not figure out why.
