To test this theory, the researchers collected fluids in isobaric gas-tight samplers (IGTs) from black smokers and analyzed them for the presence of methanethiol.

One of the greatest mysteries facing humans is how life originated on Earth. Scientists have determined approximately when life began (roughly 3.8 billion years ago), but there is still intense debate about exactly how life began.
(From ScienceDaily) – One possibility — that simple metabolic reactions emerged near ancient seafloor hot springs, enabling the leap from a non-living to a living world — has grown in popularity in the last two decades. Read the full story »
