For decades, evolutionary biologists have relied on two distinct libraries of genetic information to reconstruct the tree of ...

A tiny molecular scissor that once barely worked in human cells has been transformed into a high-performance genome-editing ...

Clues emerging from DNA could unlock the mystery of human ancestors that are missing from the fossil record yet present in the genes of people living today. Scientists found evidence years ago that ...

Nevertheless, some preliminary steps have been taken. Researchers have managed to add some new amino acids to a bacterial cell and were able to make proteins that were one amino acid less than usual.

Messenger RNA vaccines and other protein-coding nucleic acid therapeutics are among the fastest-growing classes of medicines, with billions of doses already administered worldwide. Their design relies ...

Healthy brains may be built through a process of controlled damage and rapid repair. The most dangerous type of DNA damage is a regular feature of healthy early brain development, experiments in mice ...

The genetic code is central to life. With minor variations, everything uses the same sets of three DNA bases to encode the same 20 amino acids. We have discovered no major exceptions to this, leading ...

All natural organisms use the same 20 amino acids as building blocks for proteins, but it may be possible to create a synthetic cell using a slightly smaller alphabet. Liu et al. used computational ...

Researchers recently identified food DNA on the Shroud of Turin — a finding that suggests the burial cloth believed to have wrapped Jesus Christ may have been contaminated over time. In a preprint ...
