Scientists unearth megaraptors, feathered dinosaur fossils in Chile’s Patagonia
Scientists in Chile’s Patagonia region are unearthing the southernmost dinosaur fossils recorded outside Antarctica, including remains of megaraptors that would have dominated the area’s food chain before their mass extinction. Fossils of megaraptors, a carnivorous dinosaur that inhabited parts of South America during the Cretaceous period some 70 million years ago, were found in sizes up to 10 meters long, according to the Journal of South American Earth Sciences.
Move over Ben Franklin: Laser lightning rod electrifies scientists
When Benjamin Franklin fashioned the first lightning rod in the 1750s following his famous experiment flying a kite with a key attached during a thunderstorm, the American inventor had no way of knowing this would remain the state of the art for centuries. Scientists now are moving to improve on that 18th century innovation with 21st century technology – a system employing a high-powered laser that may revolutionize lightning protection. Researchers said on Monday they succeeded in using a laser aimed at the sky from atop Mount Santis in northeastern Switzerland to divert lightning strikes.
