Protein From Space

The first known protein of extraterrestrial origin has been located by scientists inside a meteor that crashed to earth. Although the protein they discovered could easily have been an earth protein, as it was very similar chemically, the ratio of deuterium to hydrogen in the molecule was not consistent with earth chemistry and was, in fact, more consistent with an origin on a comet. The meteorite in question fell in Algeria in 1990, but new techniques uncovered the protein.
