ChemistryNew 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.

MicrobesBuried Antarctic lake teems with life
Last year, scientists drilled 800 meters (roughly a half mile) down through ice to reach a pitch-black Antarctic lake. They now report that lake hosts a thriving community of one-celled microbes.
