Video Shows How Bacteria Invade Antibiotics And Transform Into Superbugs (npr.org)

guises writes: By making a giant petri dish out of bands of increasingly antibiotic-laced agar, a couple of microbiologists have created a means to watch bacterial evolution as it happens: colonies introduced to the dish expand to fill the areas in which they can survive and then mutate and spread into the areas in which they can not. It takes only eleven days for the bacteria to evolve sufficient resistance to survive in an area with a thousand times the concentration of antibiotics that would have killed the original colonies. And it makes a pretty neat video.

  1. DNA analysis? by ceo2 · · Score: 4, Interesting

    has anyone compared the DNA of the final generations to determine if they are genetically identical or radically different?

    Among other things, to analyse the resultant resistant strains and how they developed their resistance. Doing such things they have found that there's no one method to develop resistance. That kind of data and testing has also been used to develop new methods to help fight the resistant strains, though of course, they eventually adapt to those as well since none of our methods are 100% effective at wiping them out, thus there is always the possibility to develop resistance.

    Too bad a bunch of other avowed Christians were likely responsible for cutting Turing's life in half. Also, I'll give you Babbage, but Boole was leaning hard towards deist.
