Hope it's not a repeat.

Levin stands by his claim, and he is no longer alone. Joe Miller, a cell biologist at the University of Southern California in Los Angeles, has re-analysed the data and he thinks that the emissions show evidence of a circadian cycle. That is highly suggestive of life.

Levin is petitioning ESA and NASA to fly a modified version of his mission to look for “chiral” molecules. These come in left or right-handed versions: they are mirror images of each other. While biological processes tend to produce molecules that favour one chirality over the other, non-living processes create left and right-handed versions in equal numbers. If a future mission to Mars were to find that Martian “metabolism” also prefers one chiral form of a molecule to the other, that would be the best indication yet of life on Mars.

All very interesting, but it's all new to me so it's going to take a while to sink in.

“Something on Mars is ingesting nutrients, metabolising them and then belching out radioactive methane”

Something?

Spooky.

Space worms, very hard to get rid of.
