Scientists in China have discovered the oldest dinosaur that had feathers. Thought to be between 1 to 11 million years older than the first known bird, the dinosaur, named Anchiornis huxley, was about 28 centimeters tall at its hip. From Science News:
Two types of feather adorn the creature, said (Xing) Xu, of the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing. One kind, commonly referred to as “dino-fuzz,” resembles a frayed bundle of filaments. The other type, similar in overall structure to the feathers of modern-day birds, consists of small filaments that branch from a larger shaftlike filament.
The dino-fuzz decorates the creature’s head and neck. About two dozen of the shafted feathers adorn each forelimb, and a similar number embellish each lower leg and foot, the researchers report. Unlike most feathered dinosaurs described previously, which have the longest forelimb feathers near the tip of the limb, Anchiornis’ longest forelimb feathers are on the wrist, Xu said. Feathers on the legs and feet appear to have overlapped each other, creating aerodynamic surfaces that would have, in essence, given Anchiornis a wing on each of its four limbs
Researchers at UC Riverside and Centro de Investigación Científica y de Educación Superior de Ensenada have published a paper describing their ongoing success in setting a “transparent nanocrystalline yttria-stabilized-zirconia” into patients’ skulls, which reveal the patients’ brains so that the patients’ brains can be zapped with therapeutic lasers.
One million miles from Earth, hanging in space between Earth’s gravitational pull and the sun’s, is the DSCOVR satellite and NASA’s incredible EPIC camera. Every two hours, EPIC takes a photo of Earth “to monitor ozone and aerosol levels in Earth’s atmosphere, cloud height, vegetation properties and the ultraviolet reflectivity of Earth.” The above video […]
In Botswana, conservation scientists from the University of New South Wales are painting eyes on the rear ends of cattle in an effort to deter lions from eating them. As the lions’ protected habitats shrink, they move closer to human settlements. In Botswana, the lions attack the livestock that the subsistence farmers count on. That […]
3D printers are hot, but they’re also pricey. While the prospect of cranking out everything we can dream up is enticing, cost is often one factor that keeps us from jumping onto the 3D printing train.Now, thanks to M3D, that doesn’t have to be the case. You can now get its flagship 3D printer–plus four reels of filaments–for just […]
It’s no secret that technology is changing the way we all work—but it’s also transforming the way we play. The games of today look nothing like those of 10 or even 20 years ago: these days it’s all about mobile and 3D. And now you can learn to design 3D mobile games with the Intro to Unity 3D Game […]
