Origin & Evolution of Life: May 2015


Carbonaceous chondrites are a class of meteorite known for having a high content of water and organics.

Astronomers have long held that water -- two hydrogen atoms and an oxygen atom -- was a relative latecomer to the universe. They believed that any element heavier than helium had to have been formed in the cores of stars and not by the Big Bang itself.

Together with colleagues from Uppsala University in Sweden and the University of Vienna in Austria, Steffen Leth Jrgensen from the Centre for Geobiology at the University of Bergen (UiB) has published the article Complex Archaea that bridge the gap between prokaryotes and eukaryotes in Nature, presenting the discovery of this new microbe.

DNA is synonymous with life, but where did it originate? One way to answer this question is to try to recreate the conditions that formed DNA's molecular precursors.
