A new study finds that at least one Archaea has surprisingly flexibility when interpreting genetic code, which goes against a ...

A four–amino acid peptide called CAQK has shown powerful brain-protective effects in animal models of traumatic brain injury. Delivered through a standard IV, it zeroes in on injured brain tissue, ...

To ensure that protein production in our cells runs smoothly, the protein complex NAC slows down the rate of protein synthesis right at the start. An international research team with significant ...

Proteins are among the most important molecular building blocks of life. They are chains of amino acids assembled in our cells by ribosomes, the molecular "protein factories" of our bodies. The ...

Your next favorite true crime podcast might have some new forensics jargon to make sense of. Researchers in Australia have developed a new way to identify humans – similar to how we do with DNA and ...

Researchers from ETH Zurich have modified a bacterial transport system so that it can efficiently introduce large quantities of unnatural amino acids into cells, disguised as a kind of Trojan horse.

The authors' approach to use genetic code expansion to tag two ALS proteins associated with stress granules has value and should be useful in the ALS field. Parts of the work are well done, but there ...

One of the most elegant theories about the origins of life on our planet is that it was kick-started by a delivery from outer space. This idea suggests that prebiotic molecules—the building blocks of ...

The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 ...

MIT scientists have found that an amino acid called cysteine can help the gut heal itself. In mouse studies, a cysteine-rich diet activated immune cells that release a molecule speeding up tissue ...
