Does life grow like this elsewhere in the cosmos?
... enough for the green rust to react with in order to produce the amino acid alanine and the alpha hydroxy acid lactate. These latter acids are byproducts of amino acid reactions, however some scientists theorise they too could bond to form...

Possible recipe for life on early Earth
... reactions, Krishnamurthy and team found that in addition to CO2, the chemistry also produced these much needed amino acids. The researchers think that as biological molecules like enzymes became available, they could have led to the...

Dust is the key to producing complex organic molecules in space
... to explain the origin of life. The simplest sugar glycolaldehyde (CH2OHCHO), for example, is involved in the formation of amino acids and can react with another sugar, propenal, to produce ribose. Ribose is an important component of nucleotides, and...

Scientists discover a chiral molecule outside of our solar system for the first time
...or produce. Life on Earth is made of left handed amino acids, almost exclusively, while all sugars in the metabolic pathways ... be that all living things use one enantiomer of a particular amino acid, for example, over another? If we could run the tape...

Rosetta revelations: the fabric of comet 67P/Churyumov-Gerasimenko
... have been very interesting to know if comets agree. But it still should be feasible to at least find precursor molecules of amino acids if they are there. Our Kuiper belt comet 67P/C-G seems to be a fantastic object to study. We were very much...
