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 surprising number of microbes use alternate genetic codes, different from the standard genetic code that governs the large majority of life. A census of these "recoded" genomes was recently reported ...

Nobel laureate Har Gobind Khorana's groundbreaking work on the genetic code, deciphering how DNA sequences translate to ...

Despite awe-inspiring diversity, nearly every lifeform – from bacteria to blue whales – shares the same genetic code. How and when this code came about has been the subject of much scientific ...
