8、s, scientists have found frozen bacteria and algae that returned to life after thawing. 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 fee
9、t ice to collect samples of bacteria and algae. When Dorans team brought them back and warmed them up a bit, they sprang back to life.

They will then drill through the full 62 feet of ice and sample some of the briny water from the lake for analysis. The water specimen will be cultured to see if it contains life. Specimens from the water
