Non-invasive spinal cord stimulation gets paralyzed legs moving voluntarily again

By - July 30, 2015 1 Picture

Five men with complete motor paralysis have regained the ability to move their legs voluntarily and produce step-like movements after being treated with a non-invasive form of spinal cord stimulation. The new treatment builds on prior work to generate voluntary movements in paralyzed people through electrical stimulation – in particular, two studies (one completed in 2011, the other in 2014) that involved surgically implanting an electrode array on the spinal cord. This time, however, the researchers found success without performing any invasive surgery.

New map reveals a third of the stars in the Milky Way have dramatically changed orbit

By - July 30, 2015 1 Picture

It's easy to think of stars as being fixed in place, because that's how we see them in the sky. But like Earth and the other planets, they have orbits. And it turns out those orbits can change dramatically. In creating a new map of the Milky Way as part of the Sloan Digital Sky Survey (SDSS), scientists recently discovered that around 30 percent of the stars in our galaxy have done exactly that – they've moved into a totally new orbit.

Bionicon's e-ram mountain bike motor is light and low-profile

By - July 29, 2015 4 Pictures

While hub motors may be quite common on commuter e-bikes, they’re not so popular on full-suspension electric mountain bikes. That’s because they add unsprung weight, which nobody wants. Various companies have responded by developing motors that are located in the middle of the bike, near the bottom bracket. These solve part of the problem, although they have to actually be built into the frame. That’s why Germany’s Bionicon has created the e-ram – it’s reportedly the world’s lightest mid-mount motor, and it could potentially be installed on existing mountain bikes.

Zaha Hadid's museum in the mountain opens for business

By - July 29, 2015 10 Pictures

Jutting out of the peak of Kronplatz mountain in Italy's South Tyrol region like a futuristic Bond baddie's lair, the Messner Mountain Museum Corones is classic Zaha Hadid with its curved concrete and striking glazing. Three sections exit the mountain at 2,275 m (7,463 ft) above sea level, but the greater part of the building is actually hidden from view. Here, embedded into the rock, an exhibition that promotes the traditions, history and discipline of mountaineering can be found.

The United States National Transportation Safety Board (NTSB) released the conclusions of its accident investigation into the crash of Virgin Galactic's SpaceShipTwo last year over the Mojave Desert. According to the report, the accident was due to an error by the co-pilot, who prematurely released the spacecraft's feather system, placing too much stress on the fuselage and causing it to break up.

Morphing tire concept adapts to suit driving conditions

By - July 28, 2015 4 Pictures

As the point of contact between a vehicle and the road, tires are one of the most important parts of a car. Unfortunately, there's no one size fits all, or rather, one tire fits all surfaces or weather conditions, tire and swapping them over when encountering changing conditions isn't exactly feasible. Kumho has come up with a concept tire that would avoid this problem by changing its tread to suit the conditions.
