Neanderthal ear turns up in unexpected place, muddling evolutionary pictureA distinct inner ear bone formation thought to be unique to Neanderthals has turned up in a very different sort of ancient human found in China.
Biggest flying bird ever: How did it get off the ground?A new fossil, Pelagornis sandersi, may have had the largest wingspan of any flying bird to exist, according to researchers. Once in the air, the humungous bird glided on air currents.
Can we predict floods from space?Using satellite data of how much water is stored in river basins, researchers say they have determined a new way to predict which rivers are likely to flood.
Ocean on Saturn's moon could be as salty as Dead Sea, say scientistsGravity data gathered by NASA's Cassini probe suggests that the subsurface ocean of Saturn's largest moon, Titan, has a remarkably high concentration of dissolved salts.

More than 500 marine fossils, including giant shark teeth and portions of a whale skeleton, have been unearthed at the Calaveras Dam project in Fremont, Calif.
Tibetans inherited high-altitude gene from extinct human lineage, say scientistsTibetans are adapted to rarefied air thanks to a gene passed down from the Denisovans, a group of extinct humans markedly distinct from our own species.
New wasp species has a lot of exoskeletons in the closet, say scientistsThe bone-house wasp, a newly discovered species, defends its home by stuffing ant corpses into its walls, researchers report.
Prehistoric dino-bird wore feathery pants, say scientists. But why?A new fossil of an early bird, Archaeopteryx, displays evidence of long feathers around the animal's legs, researchers say. But these feathers may not have been for flight.
