Kgnu - How On Earth

Mutant Proteins and Protein Evolution (starts 4:42) CU School of Medicine professor David Pollock explains why he has devised a new way to identify and predict both the evolution of proteins and disease causing protein mutations.    Pollock's highly technical model uses an analogy about a physical model called the Stokes Shift to help explain the biochemical properties of how proteins change, for better or worse.  Pollock's study has just been published in the journal Nature Ecology and Evolution.  Its title is “Sequence entropy of folding and the absolute rate of amino acid substitutions.”  Additionally, he has written a "behind the paper" explanation for a more general audience to explain the concepts being explored in his ground-breaking research. Soonish: Ten Emerging Technologies That’ll Improve and/or Ruin Everything (starts 15:00) Dr. Kelly Weinersmith is an adjunct assistant professor in the BioSciences Department at Rice University. She specializes in the study of parasites.  But her curiosity has ta
