Scientists have begun the search for extraterrestrial life in the solar system in earnest, but such life may be subtly or profoundly different from Earth life, and methods based on detecting particular molecules as biosignatures may not apply to life with a different evolutionary history. A new study by a joint Japan/US-based team, led by researchers at the Earth-Life Science Institute (ELSI) at the Tokyo Institute of Technology, reports on a machine learning technique that assesses complex organic mixtures using mass spectrometry to classify them as biological or abiological.
