Study also suggests dwarf planet in asteroid belt may be a source of rich organic matter. A detailed study of blue salt crystals found in two meteorites that crashed to Earth – which included X-ray experiments found that they contain both liquid water and a mix of complex organic compounds including hydrocarbons and amino acids. A detailed study of the chemical makeup within the tiny crystals, which included results from X-ray experiments also found evidence for the pair’s past intermingling and likely parents...

Chemists at The Scripps Research Institute (TSRI) have found a compound that may have been a crucial factor in the origins of life on Earth. Origins-of-life researchers have hypothesized that a chemical reaction called phosphorylation may have been crucial for the assembly of three key ingredients in early life forms: short strands of nucleotides to store genetic information, short chains of amino acids (peptides) to do the main work of cells, and lipids to form encapsulating structures such as cell walls. Yet, no one has ever found a phosphorylating agent that was plausibly present on early Earth and could have produced these three classes of molecules side-by-side under the same realistic conditions.
TSRI chemists have now identified just such a compound: diamidoph...
