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 ...

Amino acids are organic compounds that serve as the fundamental building blocks of proteins. They play a crucial role in the structure, function, and regulation of the body's tissues and organs. Amino ...

Amino acids, the building blocks necessary for life, were previously found in samples of 4.6-billion-year-old rocks from an ...

The amino acid abundances of two Ryugu particles were measured and compared with their rocky components. The results demonstrate the important role that water plays in the formation of amino acids on ...

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 ...
