A new microfluidics chip developed by researchers at Princeton University is showing that bacteria evolve resistance to antibiotics much more quickly, and more predictably, than previously thought, reports Technology Review's Lauren Gravitz. The chip, dubbed the "death galaxy" by its inventor Robert Austin, simulates the complex environment that bacteria experience in the human body — it contains more than 1,000 hexagonal chambers, each of which is a microhabitat, Gravitz says.
