When a small, sparrow-sized dinosaur died about 99 million years ago, part of its tail was immaculately preserved in amber. Researchers who recently discovered the tail from a Hukawng Valley amber mine in Myanmar say it’s a notable find not only because it is the first dinosaur tail ever identified, but also because it is covered in feathers. Co-first author Lida Xing of China University of Geosciences found the amber piece in a Myanmar market in 2015, according to NPR . The Dexu Institute of Palaeontology agreed to purchase the specimen, and Xing and colleagues got to work scrutinizing it.

Scientists can tell it was tiny from the tail bone, which is a mere two millimeters across. Part of the mystery of dinosaurs with feathers is that many probably didn’t use that plumage to fly. The structure of the little dinosaur’s feathers instead resembles ornamental feathers seen on some modern birds . Scientists can see the way the feathers’ barbs bend means they’re far more flexible than feathers used for flight, and could have been employed to send signals or regulate the dinosaur’s temperature. The top of the feathers could have been dark brown, the scientists think, with the underside having no color at all. That or carotenoids – pigments responsible for orange, red, and yellow hues – may have brightened the underside feathers in life but broke down swiftly when the dinosaur died. Thrilled with the discovery, the scientists hope they might be able to find even more specimens in the future. With a conflict between the Kachin Independence Army – who currently possess the Hukawng Valley – and the Myanmar government hopefully coming to a close, scientists may be able to get more access to the amber mines, according to Xing. He speculated they might even find a whole dinosaur one day. 14 scientists from international institutions participated in a new study published by the journal Current Biology .

Autonomous concept car features an urban garden on wheels

Comments Off on Autonomous concept car features an urban garden on wheels

From a Swiss think tank widely known for its outrageous car concepts comes the automotive dream to end all others: an autonomous vehicle featuring a mobile office and a living garden . The Rinspeed Oasis is set to be unveiled at the upcoming CES event held in Las Vegas in early January 2017. The fully autonomous concept vehicle takes a wildly different approach to commuting, with a built-in personal assistant, a lock-box for packages, and a host of other smart features that change the way we think about transportation. Rinspeed has promoted the “mobile office” notion in previous concept designs, and the Swiss think tank even transformed a Tesla Model S into a self-driving office on wheels. With the debut of the Oasis concept next month, Rinspeed is upping the stakes quite a bit in terms of innovation and thinking outside the literal box of a car frame. That’s the whole point of the Oasis concept, according to the company’s press release, which acknowledges some critics might be scratching their heads at the notion of growing plants inside a car. Related: Rinspeed turns Tesla Model S into an autonomous mobile office “Urban gardening on wheels as a new trend? A little bit out there? Maybe. But as always, the creation of Swiss mobility innovator Frank M. Rinderknecht is an oasis for inspiration in the otherwise rather expansive automotive wasteland,” the company said. The Oasis also features an onboard “personal assistant” that puts artificial intelligence to work for the car owner by linking personal data (via digital calendar and social media accounts, for instance) with the vehicle’s navigation system and traffic information. As a result, the vehicle can not only let you know whether you’ll make it to your destination on time, but can also give you a heads up if you’re about to miss an appointment. Let’s be clear about one thing: there are no plans for mass production currently in place. At CES, Rinspeed will do what they do for another year in row, which is reveal outlandish concepts to push the envelope of automotive design and hope that carmakers will follow.
