Durable proteins make life possible in the crushing depths of the ocean, and may have evolved in life below the surface of ice-bound oceanic exo-planets. These proteins stay folded – allowing them to ...
Sequence data of biomolecules such as DNA and proteins, which provide critical information for evolutionary studies, have been assumed to be forever outside the reach of dinosaur paleontology. Protein...
