Scientists discover new 'origins of life' chemical reactions

Four billion years ago, the Earth looked very different than it does today, devoid of life and covered by a vast ocean. Over the course of millions of years, in that primordial soup, life emerged. Researchers have long theorized ...

Early Earth's atmosphere was less conducive to lightning

In 1952, Stanley Miller and Harold Urey made sparks fly in a gas-filled flask meant to reflect the composition of Earth's atmosphere around 3.8 billion years ago. Their results suggested that lightning could have led to prebiotic ...

Stable majorities

How could prebiotic information-bearing DNA sequences survive in the face of competition from a vast excess of shorter molecules with random sequences? LMU scientists now show that a relatively simple mechanism could have ...

Halfway mark for NOEMA construction

The completion of NOEMA phase 1, the first phase of the NOEMA project will be officially celebrated this Wednesday, September 19th. IRAM and its partner institutes have completed the first, decisive step towards one of the ...

Enzymes allow DNA to swap information with exotic molecules

(Phys.org) —The discovery of the Rosetta Stone resolved a longstanding puzzle, permitting the translation of Egyptian hieroglyphs into Ancient Greek. John Chaput, a researcher at Arizona State University's Biodesign Institute ...

RNA reactor could have served as a precursor of life

(PhysOrg.com) -- Nobody knows quite how life originated on Earth, but most scientists agree that living cells did not abruptly appear from nonliving cells in a single step. Instead, there were probably a series of pre-cellular ...
