iPod sized device to monitor fetal heartbeat

Discerning the heartbeat of a baby still in the womb is a bit like making out a murmur in a crowded room. However, researchers at the University of Nottingham have designed a fetal heart monitor that can accurately distinguish a fetus's heart rate from its mother's and from surrounding noises. What's more, they've made the device noninvasive, small, and easy to use in the home.
