A big question in the origin of life on Earth is why it is based solely on "left-handed" amino acids. Studies on asteroid Bennu's chemical building blocks deepens the mystery. Credit: Christoph ...

In a peer-reviewed analysis, scientists quantify amino acids before and after our “last universal common ancestor.” The last universal common ancestor (LUCA) is the single life form that branched into ...
