Study: Organic molecules discovered by Curiosity Rover consistent with early life on Mars

Organic compounds called thiophenes are found on Earth in coal, crude oil and oddly enough, in white truffles, the mushroom beloved by epicureans and wild pigs. Thiophenes were also recently discovered on Mars, and Washington State University astrobiologist Dirk Schulze-Makuch thinks their presence would be consistent with the presence of early life on Mars. This study explores some of the possible pathways for thiophenes' origins on the red planet.
