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 ...

Mechanochemical peptide bond formation behind the origins of life

The presence of amino acids on the prebiotic Earth is widely accepted, either coming from endogenous chemical processes or being delivered by extraterrestrial material. On the other hand, plausibly prebiotic pathways to peptides ...

Horse nutrition: Prebiotics do more harm than good

Prebiotics are only able to help stabilise the intestinal flora of horses to a limited degree. Before they can reach the intestines, commercially available supplements partially break down in the animals' stomachs, which ...

Forest and sea residues strengthen the stomach

With the help of forest residues such as sawdust, branches and tops (GROT), and cellulose from sea squirts, researchers in Biochemical Process Engineering at LuleƄ University of Technology want to make our stomach to feel ...

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 ...
