Life on Mars? Tiny cells just survived shock waves and toxic soil

Mars may be hostile, but it might not be entirely unlivable. In lab experiments, yeast cells survived simulated Martian shock waves and toxic perchlorate salts—two major environmental threats on the Red Planet. Their secret weapon was forming protective molecular clusters that shield critical cellular functions under stress. Without these defenses, survival plummeted, pointing to a potential universal strategy life could use beyond Earth.
