Scientists watch as bacteria evolve antibiotic resistance

    For bacteria, practice makes perfect: Adjusting to ever higher levels of antibiotics preps them to morph into super resistant strains, and scientists can now watch it happen. A new device — a huge petri dish coated with different concentrations of antibiotics — makes this normally hidden process visible, microbiologist Michael Baym and colleagues report in the Sept. 9 Science. The setup gives a step-by-step picture of how garden-variety microbes become antibiotic-resistant superbugs.

    “As someone who’s studied evolutionary biology for a long time, I think it has a real wow factor,” says Sam Brown, a microbiologist at the Georgia Institute of Technology in Atlanta who wasn’t involved in the study. The bacteria are “climbing this impossible mountain of antibiotics.” ...

    Great experiment! Thanks for sharing!
    This reminds me of a paper I read recently: Antibiotic resistance: a physicist’s view
