New Clues to Alien Life: Researchers Revive 4-Billion-Year-Old Metabolic Process

The earliest cells harnessed energy through geochemical reactions, a process that LMU researchers have now successfully replicated in the lab. The earliest ancestor of all life on Earth likely thrived in warm environments, relied on hydrogen for energy, and produced methane as a byproduct. Researchers at LMU Munich have reached this conclusion through fossil evidence [...]
