Evidence of diverse life forms dating back nearly a hundred thousand years has been found in subglacial lake sediments by a group of British scientists. The possibility that extreme life forms might exist in the cold and dark lakes hidden kilometres beneath the Antarctic ice sheet has fascinated scientists for decades.
Microbes are living more than 500 feet beneath the seafloor in 5 million-year-old sediment, according to new findings by researchers at the University of Delaware and Woods Hole Oceanographic Institution (WHOI).
Scientists at Cambridge University say they've worked out why the tsunami that devastated Japan in March 2011 was so much larger than expected.
Living bacteria have been discovered deep beneath the ocean where they've had no new food or oxygen since dinosaurs roamed the earth.
Frequent periods of intense global warming took place in the distant past, say researchers at UC San Diego's Scripps Institution of Oceanography.
