Where is the best place to find low-cost, easy-to-produce, natural, robust and non toxic antibiotics? Easy, in our own bodies. Nature so often provides the solutions we are looking for and, as an aside, that is why the preservation of species from extinction is so important. In this case the solution is natural antibiotics which University of California at Berkeley researchers have confirmed to exist in the tails of certain proteins called cytokeratins. These proteins help our eyes, for example, ward off infections. The eye’s cornea is remarkably free of pathogens and the research reveals something about how these wonderful proteins work. Once again, however, the research was not motivated by evolutionary theory. Read more
