A new safety device uses snow’s natural porosity to supply oxygen to buried avalanche victims, extending the window for rescue.
Safety Device Supplies Life-Saving Air in an Avalanche - Eos
An Alpine medical team buried 24 volunteers in a mountain pass. Their study confirmed the efficacy of the Safeback SBX, which uses snow’s natural porosity to supply air to buried avalanche victims.

Hydrology Paper of the Day @eos.org on changes in microbial diversity in the Arctic and and possibility of soils acting as a carbon sink in a warming world: microbiome shifts and biogeochemical cycles in the pan-Arctic; samples from intact permafrost sites; and the mediating role of hydrology.
Is there a “methane bomb” lying in Arctic permafrost? New research suggests the answer is complicated—warming Arctic soils might help or hurt the climate, depending on other factors like hydrology. eos.org/articles/in-...
In Arctic Soils, Methane-Eating Microbes Just Might Win Out over Methane Makers - Eos
Methanotrophs, including those that capture methane from the air, seem to outcompete methanogens in dry environments, a new study shows.
