Via New Scientist:

It's relatively well understood how the first fish began to move on landMovie Camera and breathe in air, but how vertebrates switched from feeding via suction to evolve a tongue remains unclear. Seeking an answer, Krijn Michel at the University of Antwerp in Belgium and his colleagues looked to the mudskipper.

They captured high-speed X-ray footage of Atlantic mudskippers (Periophthalmus barbarus) out of water pouncing and chowing down on pieces of brown shrimp. The move takes less than half a second but, slowed down 50 times, they spotted that mudskippers carry water in their mouths, which they spit forwards to help grab food then suck it back to swallow, mimicking the action of a tongue.

NASA's Orion spacecraft, which could one day send astronauts to Mars, is stuck on terra firma for at least another day after the space agency's mission control was unable to satisfactorily resolve a number of issues before a 9:45 a.m. ET launch window closed.

The unmanned vehicle is awaiting its first test in Earth orbit. But after multiple delays for high winds and a stuck liquid-oxygen drain valve on one or more of the Delta IV Heavy rocket's booster engines, NASA didn't have time to get the rocket off the pad. It will try again Friday morning.
