'Dancing dragon' shows feathers grew differently on dinosaurs and birds
An exquisite fossil of a fierce little Chinese dinosaur dubbed the "dancing dragon" that lived 120 million years ago - an older cousin of the Velociraptor - is showing scientists that feathers grew differently on dinosaurs than on birds. The two-legged Cretaceous Period dinosaur, called Wulong bohaiensis, was a bantamweight meat-eater - a bit bigger than a crow - residing in a lakeside environment, researchers said. It possessed a scaly face, a mouth full of pointy teeth and one particularly dangerous toe claw, and probably hunted small mammals, lizards, birds and fish.
Bad weather forces delay of SpaceX simulated rocket failure test

The test, the company's final milestone test before flying NASA astronauts from U.S. soil, had been planned to take place on Saturday.
