Sleeping Through the Blitz

It's not just antibiotic-resistant bacteria that we have to worry about. Hit bacteria with antibiotics and they can evolve tolerance: they can sleep through the drug assault with an astonishingly precise timer. They keep their head down for exactly the right time, wait for danger to pass, and start growing again. And once they evolve this way against one antibiotic, they could potentially withstand any of them. (Image: Sean McGrath)

The Bird That Paints Its Eggs With Bacteria

Look under the tail feathers of any bird and you’ll find the uropygial gland, or preen gland. It secretes oils and waxes that birds use to clean and waterproof their feathers. But the hoopoe's gland is different--during the breeding season, it becomes exceptionally large and makes a weird dark brown fluid that smells of rotting meat.
