Our Communications Earth & Environment study presents evidence that glacial lake outburst floods (GLOFs) may provide biological stimuli to carbon dioxide-depleted benthic ecosystems in perennially ice-covered Antarctic lakes and perhaps even in icy lakes on early Mars.

Antimonite has potential applications for solar energy, but how its layered structure changes under pressure is incompletely understood. Here diamond anvil cell experiments supported by first principles calculations offer a structural explanation for experimentally observed phase transitions.
