By treating DNA as a language, Brian Hie’s “ChatGPT for genomes” could pick up patterns that humans can’t see, accelerating ...

DNA methylation is the covalent addition of methyl groups to DNA bases, typically the cytosine of CpG dinucleotides. It is catalyzed by methyltransferase enzymes using a S-adenosyl methionine ...

Comparison of that ancient DNA with modern human DNA showed that the two species had interbred and that people today still carry the genetic fingerprint of that intermixing. Since then ...

For the study, the diversity of bacteria and archaea of each individual sample was determined using DNA sequences, and the diversity found in all samples from a particular biome used to determine ...

Of course, though, testing a child's parentage based on physical features is far too subjective — that's typically where DNA tests come in. Such tests can offer a far more scientific way of ...

Cornell researchers have discovered a way for ammonia oxidizing archaea (AOA), one of the most abundant types of microorganisms on Earth, to produce nitrous oxide, a potent and long-lasting ...

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means ...

A 2015 report published by a private genomics testing company found that 2% of 345 hot dogs tested contained traces of human DNA. However, it was unclear whether that report was a peer-reviewed ...

As she worked at her computer, the results revealed the sample she was examining contained human DNA. There was nothing so unusual about that in itself: at the time, the ancient DNA (aDNA ...
