First vision of bacteria "harpooning" DNA to accelerate evolution

Bacteria evolve fast – and that could be bad news for those of us who don't want to see easily-treatable diseases make a roaring comeback. Resistance to antibiotics is a growing concern, but if scientists can see how the microbes evolve, they might be able to intervene. Now researchers at Indiana University have peeked into that tiny world, producing the first direct images of bacteria extending "harpoons" to snare and absorb bits of DNA...
