New Evidence for Life on Mars

The BBC is reporting on new evidence that life existed on Mars. It revolves around the unique properties of magnetsomes: tiny magnetic crystals of iron that some terrestrial bacteria produce to sense the Earth's magnetic field. Magnetosomes are far purer than magnetite grains that occur naturally. The research of Nasa's Dr Kathie Thomas-Keprta indicates magnetite produced by bacteria-like microorganisms is present in the Allen Hills meteorite, a Mars rock picked up in the Allen Hills region of Antarctica.
