Nanostructures found in deep ocean vents could shed light on life's origins
Tokyo, Japan (SPX) Sep 26, 2024 Researchers from the RIKEN Center for Sustainable Resource Science (CSRS) and the Earth-Life Science Institute (ELSI) at the Tokyo Institute of Technology have uncovered inorganic nanostructures around deep-ocean hydrothermal vents that closely resemble key molecules involved in life processes. These self-organized nanostructures function as selective ion channels, generating energy that can be captured as electricity. The findings, published on Sep. 25 in 'Nature Communications', hold significant impli ... read more |

Deep ocean 'dark oxygen' find could rewrite Earth's history
Paris (AFP) July 22, 2024 In the total darkness of the depths of the Pacific Ocean, scientists have discovered oxygen being produced not by living organisms but by strange potato-shaped metallic lumps that give off almost as much electricity as AA batteries. The surprise finding has many potential implications and could even require rethinking how life first began on Earth, the researchers behind a new study said on Monday. It had been thought that only living things such as plants and algae were capable of producing oxy ... read more
