Extreme Life

    • Looking for life, Astrobiologists Dive Deep
      Coral-like mounds on the floor of a Canadian lake may make it easier someday to identify life on other planets.
    • Terrestrial Powerhouses
      A remarkable protein called bacteriorhodopsin converts light into metabolic energy. After 30 years of investigations, this protein has finally revealed some of its secrets.
    • Pyruving the Origin of Life
      For the origin of life, chemical synthesis of pyruvic acid is a critical step. In a difficult experiment, Carnegie Institute/NAI researchers report that the natural synthesis of such compounds would occur wherever hot ocean vents pass through iron sulfide-containing crust.
