Walkera Voyager 4 superzoom camera drone with unlimited control range

The Walkera Voyager 4 prosumer-grade camera drone packs a 16x optical superzoom lens

Walkera has beefed up its prosumer level flagship camera drone with two killer new features. The Voyager 4 has a gimbal-stabilized, 360-degree camera with a 16x optical zoom lens capable of a maximum 1,500 mm focal length. Plus, with both the drone and the controller connected to 4G wireless internet, there's no limit on control range, so you could literally fly this thing from the other side of the world.

Hottest half-year on record sinks Arctic ice to new lows

An image of Arctic sea ice captured from 1,500 feet during an Operation IceBridge mission

Last month, scientists reported an earlier-than-normal annual melting of Arctic sea ice, and now NASA researchers taking further stock of the situation are providing a clearer picture of exactly how fast it is shrinking and the reasons why. As Earth sweats through its hottest six-month period on record, analysis of the same timeframe has revealed record-breaking shrinking of Arctic sea ice, with total coverage at the height of the melting season now 40 percent less than in the late 1970s.

Same object, different sound thanks to acoustic voxels

Researchers at Columbia Engineering have developed a system that can endow a 3D-printed object with unique ...

3D-printed motorcycle earmuffs that suppress traffic and wind noise while amplifying car horns, and objects encoded with unique audio barcodes are just a couple of the devices that could be on the way, thanks to a new system designed by researchers at Columbia University, MIT and Disney Research that allows specific acoustic properties to be implanted into 3D-printed objects.

BratWurst Bot serves up brats in Berlin

BratWurst Bot served up over 200 sausages that it grilled autonomously

A cybernetic, one-armed sausage chef has been serving up steady stream of bangers for a celebrity crowd in Germany. The robotic short-order cook, called BratWurst Bot, was built by out of off-the-shelf parts as a technology demonstrator to show how easy it is to create new, practical robots without the need for special fabrication.
