The research may help in the search for life on Mars, which is thought to have subsurface lakes of ice. A research team led by Peter Doran of the University of Illinois at Chicago drilled through more than 39 feet ice to collect samples of bacteria and algae. When Doran’s team brought them back and warmed them up a bit, they sprang back to life.
