Researchers discover a unique genetic code in Antarctic archaea that encodes a rare amino acid, potentially advancing protein ...

To ensure that protein production in our cells runs smoothly, the protein complex NAC slows down the rate of protein synthesis right at the start.

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 ...

Amino acids are absolutely essential to our health—and for life itself. They are the so-called “building blocks” of proteins. They play a key role in the growth, repair, and maintenance of almost ...

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 ...
