Some archaea—an ancient group of microorganisms—have an entirely novel genetic code, according to a new study in Science.
The findings expand our understanding of how alternative genetic codes evolve and hint at new molecular tools for biotechnology applications. https://scim.ag/4omApQ7

An archaeal genetic code with all TAG codons as pyrrolysine
Multiple genetic codes developed during the evolution of eukaryotes and bacteria, yet no alternative genetic code is known for archaea. We used proteomics to confirm our prediction that certain archae...

Researchers have identified a signalling feedback loop that may have been vital to the evolution of insect wings and therefore flight.
The signals, called morphogens, act like lighthouses in most developing tissues, guiding nearby cells towards their fate.
