Astronomers Report That Venus' Atmosphere Contains a Building Block of Protein

A team of researchers claims they've discovered the amino acid glycine in Venus' atmosphere.  (The paper hasn't been peer-reviewed and published in a journal… yet.  Caution.)  There are ~500 known amino acids, but only 20 are present in the genetic code. Glycine is the simplest. Glycine and other amino acids are some of the building blocks of life, of proteins. They were also some of the first organic molecules to appear on Earth. Glycine is important for the development of proteins and other biological compounds. - Science Alert
