Learning rewires the brain
Brain cells actually change shape as we learn. It’s one way we cement new knowledge. And much of the action happens as we sleep.

New nano-cages snag and hold gases
Molecular traps have been developed to snag and hold noble gases, such as krypton, xenon and radon. These atoms tend to resist arrest. But the new traps might grab onto polluting gases so that they can be recycled for later beneficial uses.
