The building blocks of proteins, amino acids are essential for all living things. Twenty different amino acids build the thousands of proteins that ...

Dust from asteroid Bennu is revealing a surprising origin story for life’s building blocks. New research suggests some amino acids formed in frozen ice exposed to radiation, not warm liquid water as ...

Researchers demonstrated how amino acids could spontaneously attach to RNA under early Earth-like conditions using thioesters, providing a long-sought clue to the origins of protein synthesis. This ...

Although the myriad proteins found in all life are largely built from a set of 20 amino acids, many other amino acids exist in nature, and it remains a curiosity as to why some were ultimately ...
