Bleach a possible key to life on earth
Canberra, Australia (SPX) Jul 24, 2015
Hydrogen peroxide - commonly used as hair bleach - may have provided the energy source for the development of life on Earth, two applied mathematicians have found. The heat from ancient geothermal vents may have triggered the varying acidity that was vital for early life to form and spread throughout the oceans. "The energy in hydrogen peroxide could have powered the living world before cells evolved," said Associate Professor Rowena Ball, from The Australian National University (ANU). The researc ... read more
