Researchers in Australia have come up with an outwardly simple but incredibly ingenious way of curing blindness caused by corneal damage: Take everyday contact lenses, already used by millions (including me), and infuse them with a patient's own stem cells.

A good dose of nature can still soothe the psyche of the modern human, but sometimes nature, red in tooth and claw, can also just gross you out. Wasps turn helpless caterpillars into a 24x7 buffet for young ones, mama mantis snacks on the head of its former lover, and a frog gives new meaning to oral fixation when nurturing the kiddies.
