These freeze-drying algae can awaken from cryostasis, and could help spaceflights go farther
Antarctica's McMurdo Dry Valleys contain some of Earth's coldest and driest deserts. The environment there is so extreme that the Dry Valleys have been used as Mars analogs to test prototype equipment for future Mars exploration......»»
Q&A: Drying of the Salton Sea has staved off earthquakes, for now
The southern end of the San Andreas Fault that runs directly below the Salton Sea in Southern California currently poses the largest seismic hazard in the state, but the area hasn't experienced a major earthquake in more than 300 years......»»

Investigating the intricacies of auxin signaling mechanisms in algae
Phytohormones are chemical messengers that regulate the growth of plants and their response to the environment. In land plants, auxin is an important and well-studied phytohormone that affects various aspects of plant development......»»
Ecological doom-loops: Why ecosystem collapses may occur much sooner than expected
Around the world, rainforests are becoming savanna or farmland, savanna is drying out and turning into desert, and icy tundra is thawing. Indeed, scientific studies have now recorded "regime shifts" like these in more than 20 different types of ecosy.....»»
"He just kept going"—why you might snap back, freeze or ignore street harassment
