Plants provide model for new shape-changing materials

...to make a dive towards the intended victim. As the raptor changes gear to fly southward at lightening speed, it must sense what the outside forces and pressures are for its trajectory. Similarly, for an aircraft wing, engineers would need a material that's mechanically flexible. But the designers also need...

...f Natural History have identified a new species of raptor dinosaur from fossils found in Patagonia -- the very southern tip of South America. It is the first raptor ever found in the Southern Hemisphere, but compared to other raptors, Neuquenraptor argentinus wasnt...

DNA from feathers tells tale of eagle fidelity

...pecies, DeWoody said. "It's very likely that other raptor biologists will follow this with similar studies on other species of interest like bald eagles," he said. This project is one part of a larger research program on the eagles of Naurzumski Gosudarstvennyi Zapovednik (Naurzum State Nature Reserve), a l...

Ancient raptors likely feasted on early man, study suggests

... (12 kg). McGraw says that scientists think that a raptor about the same size as a modern-day African crowned eagle may have killed the young hominid. "Many people thought that an eagle of this size wouldn't have enough strength to lift a primate the size of the Taung child," McGraw said. "That's a non-iss...

Eavesdropping nuthatches distinguish danger threats in chickadee alarm calls

...ecies," said Templeton. "Nuthatches can tell if a raptor poses a high or low danger from the chickadees alarm call." His earlier work showed that the chickadees had two types of alarm calls to warn about predators. When they see flying raptors birds of prey such as hawks, owls and falcons they issue a ...

Agonized death throes probable cause of open-mouthed, head-back pose of many dino fossils

"In horses and smaller animals, rigor mortis sets in within a couple of hours, so I just looked to see if they were moving or not," Faux...
