For the first time, scientists have revealed the steps needed to turn on a receptor that helps regulate neuron firing. The findings might help researchers understand and someday treat addiction, psychosis and other neuropsychological diseases.
Cryogenic electron microscopy can in principle make out individual atoms in a molecule, but distinguishing the crisp from the blurry parts of an image can be a challenge. A new mathematical method may help.
A new understanding of the nucleation process could shed light on how the shells help microbes interact with their environments, and help people design self-assembling nanostructures for various tasks.
