Yeast exposed to 5.6 mach intensity shock waves survived with slowed growth, as did yeast subjected to 100 mm sodium salt of perchlorate (naclo4)—a concentration similar to that in martian soils. Any life on mars in the past, present, or future would have to contend with challenging conditions including, among others, shock waves from meteorite impacts and soil perchlorates—highly oxidizing salts that destabilize hydrogen bonds and hydrophobic interactions. “the results show the importance of yeast and rnp condensates in understanding the effects of martian conditions on life,” the scientists concluded
