Arrow worms, or chaetognaths, are strange ocean predators that have puzzled scientists for more than a century. They have ...

The recoded bacterium uses only 57 of the 64 possible genetic codes, freeing up seven to be used for different purposes ...

DNA contains foundational information needed to sustain life. Understanding how this information is stored and organized has been one of the greatest scientific challenges of the last century.

You'll get an ad-free account as a thank-you. More information: Wesley E. Robertson et al, Escherichia coli with a 57-codon genetic code, Science (2025). DOI: 10.1126/science.ady4368 ...

The genetics of a marine protozoan may overturn one of the long-held tenets of protein synthesis. According to conventional wisdom, the genetic code is unambiguous: each DNA triplet, or codon, ...

What scientists once dismissed as junk DNA may actually be some of the most powerful code in our genome. A new international study reveals that ancient viral DNA buried in our genes plays an ...

At the heart of all life is a code. Our cells use it to turn the information in our DNA into proteins. So do maple trees. So do hammerhead sharks. So do shiitake mushrooms. Except for some minor ...
