Scientists Recreate Mars Conditions in Lab, Yeast Cells Survive Extreme Stress
Researchers have successfully recreated hostile conditions similar to those found on Mars in a laboratory setting, using Saccharomyces cerevisiae, a yeast species. The study involved exposing these yeast cells to intense shock waves and toxic perchlorate salts, which are prevalent on Mars. The High-Intensity Shock Tube for Astrochemistry (HISTA) in India was used to generate shock waves reaching 5.6 times the speed of sound, mimicking meteorite impacts on Mars. Despite these extreme conditions, the yeast cells managed to survive, although their growth rate was reduced. The study highlights the yeast's ability to form ribonucleoprotein (RNP) condensates, which act as protective structures during stress.
