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

Cells working with an expanded genetic code could make more diverse medicines. A new study shows scientists are within striking distance. One of modern biologists' most ambitious goals is to learn how ...

A central tenet of biology may need updating given new measurements of start codons. For decades, scientists working with genetic material have labored with a few basic rules in mind. To start, DNA is ...
