A newly-designed material, which mimics the wing structure of owls, could help make wind turbines, computer fans and even planes much quieter. Early wind tunnel tests of the coating have shown a substantial reduction in noise without any noticeable effect on aerodynamics. An investigation into how owls fly and hunt in silence has enabled researchers […]
For more than 30 million years after dinosaurs first appeared, they remained inexplicably rare near the equator, where only a few small-bodied meat-eating dinosaurs made a living. The long absence at low latitudes has been one of the great, unanswered questions about the rise of the dinosaurs. Now the mystery has a solution, according to […]
A 8,500 year old male skeleton discovered in 1996 in Columbia River in Washington State has been the focus of a bitter dispute between Native Americans and American scientists, and even within the American scientific community. Craniometric analysis showed that Kennewick Man, as the skeleton was named, resembled populations in Japan, Polynesia or even Europe, […]
A team of Tel Aviv University and UCLA astronomers have discovered a remarkable cluster of more than a million young stars are forming in a hot, dusty cloud of molecular gases in a tiny galaxy very near our own. The star cluster is buried within a massive gas cloud dubbed “Cloud D” in the NGC […]
