Now, a new genetic study of electric fish has revealed the surprising way they got electrified.<p>Consider a 6-foot-long electric eel: It is basically a 6-inch fish attached to a 5-1/2-foot cattle prod, says <a href="http://www.biochem.wisc.edu/faculty/sussman/">Michael Sussman</a>, who directs the biotechnology center at the University of Wisconsin, Madison.

Inside the cabinets are more than a half-million birds — and these birds are not drab.

Big Flightless Birds Come From High-Flying Ancestors http://wcqs.org/post/big-flightless-birds-come-high-flying-ancestors Big, flightless birds like the <a href="http://animals.sandiegozoo.org/animals/ostrich">ostrich</a>, the <a href="http://animals.sandiegozoo.org/animals/emu">emu</a> and the <a href="http://animals.nationalgeographic.com/animals/birds/greater-rhea/">rhea</a> are scattered around the Southern Hemisphere because their ancestors once flew around the world, a new study suggests.<p>That's a surprise, because it means birds in Australia, Africa and South America independently evolved in ways that made them all lose the ability to fly.<p>These related birds — known as <a href="http://sciencewise.anu.

It's kind of like the eight arms have minds of their own.

The part of the ice sheath that's over West Antarctica is thought to be especially vulnerable to climate change. Scientists now say a slow collapse of the West Antarctic ice sheet is both underway and irreversible.
