An x-ray crystal structure of a eukaryotic voltage-gated potassium channel, probably in its native confirmation, reveals how movement of the voltage sensor triggers opening of the pore.

When stressed by cooling, a silica coating on silver nanoparticles forms complex, organized patterns similar to those seen in flowers and seeds.

Simulations suggest that in anionic water clusters of fewer than 200 molecules, the excess electron resides on the surface of the cluster rather than inside it.
