Scientists Resurrect 160-Million-Year-Old Molecules With Surprising Power Against Superbugs

Ancient mammalian antimicrobial peptides revealed stronger bacteria-killing activity in some cases, offering clues for designing future treatments against resistant infections. Some proteins that vanished millions of years ago may still have something to teach scientists about fighting modern infections. University of Oregon biologists have reconstructed antimicrobial molecules dating back as far as 160 million years, [...]
