Microbes before and after extreme impact (IMAGE)
Caption
After shooting the microbes, the team determined whether they survived and examined the survivors’ genetic material for clues to how they handled the pressure.
The bacteria proved very hard to kill. They survived nearly every test at 1.4 Gigapascal of pressure and 60% at 2.4 Gigapascals of pressure. The cells showed no signs of damage after the lower pressure hits, but after the higher pressure experiments, the team observed some ruptured membranes and internal damage
