Astrobiology Spinoff? Introduced Tardigrade Proteins Can Slow Metabolism In Human Cells
Editor’s note: although NASA did not sponsor research wherein tardigrade proteins were tested in human cells to see if they work – someone did. This emerged as the result of […]

Early Selection Of The Amino Acid Alphabet Was Adaptively Shaped By Biophysical Constraints Of Foldability
Whereas modern proteins rely on a quasi-universal repertoire of 20 canonical amino acids (AAs), numerous lines of evidence suggest that ancient proteins relied on a limited alphabet of 10 ‘early’ […]
