Mercedes-Benz’s CityPilot autonomous bus technology just got a real-world, long-range test drive on the streets and highways of the Netherlands. One of the company’s Future Bus vehicles successfully followed a 20km Bus Rapid Transit route between Amsterdam’s Schiphol airport and the nearby town of Haarlem, navigating through tight turns, intersections and pedestrian areas all without the need for human input.

The CityPilot platform is based on a version of Daimler’s Highway Pilot autonomous trucking technology adapted to handle the specific needs of a city bus. With GPS, radar and a dozen cameras built into the vehicle itself, the bus can recognize traffic signals, pedestrians and other obstacles. The bus has a top speed of 70km/h (or about 43 mph) and all that data taken together allows the bus to position itself within inches of bus stops or raised accessibility platforms.

Although regulations still require a human operator sit behind the wheel in case of an emergency, the vehicle’s intelligent systems make for a much smoother ride for everyone. Unlike other autonomous vehicles, the bus is actually connected to the city network so it can communicate directly with traffic lights and other city infrastructure. The camera systems can even scan the road for potholes, so buses can avoid rough patches on their next run or share that data back to the city.

3D print materials and products with superconducting properties is truly a breakthrough towards the mass production of various complex materials. I see this as a large step forward for 3D and placing things on an evolution track to even mass produce synthetic diamonds.

3D printing is revolutionizing many areas of manufacturing and science. In particular, 3D printing of metals has found novel applications in fields as diverse as customized medical implants, jet engine bearings and rapid prototyping for the automotive industry.

While many techniques can be used for 3D printing with metals, most rely on computer-controlled melting or sintering of a metal alloy powder by a laser or electron beam. The mechanical properties of parts produced by this method have been well studied, but not enough attention has focused on their electrical properties.

Now in a paper appearing this week on the cover of the journal Applied Physics Letters, a team of University of Melbourne and University of Western Australia researchers report creating a resonant microwave cavity that they 3D printed viaan aluminum-silicon alloy (Al-12Si). It exhibits superconductivity when cooled below the critical temperature of aluminum (1.2 Kelvin).

Personally, I wouldn’t state that tech got the whole wearables wrong; its more been operated in a mode of experimentation with the public in an order to perfect the technology. I believe we’re now on a track to broaden this technology to accommodate more consumers on multiple levels such as business travelers may wish to have suits and bus attire that self cleans and can (when your wearing and biosensor is activated) be leveraged to store your id information or when you’re processed through airports instead of having to juggle for your license/ passport.

The key to unlocking the $150 billion wearables market is textiles not silicon.

With more than 25 years of using 3D printing technology, there probably isn’t a global automotive manufacturer that has pushed the limits of using additive manufacturing applications than the BMW Group. For most of the quarter-century that they have been using 3D printing, it was primarily used in the production of prototypes or one-off custom parts. However BMW began using 3D printing technology to produce end-use parts in series production back in 2012 with their new Rolls-Royce Phantom. Over the next several years, more than 10,000 3D printed components would end up being used to manufacture each Phantom coupe that came off the assembly line. The switch from traditionally manufactured parts to 3D printed parts was so successful that BMW began incorporating them into the new Rolls-Royce Dawn this year.

Sad for Russia.

President Vladimir Putin and other Russian officials dream of a technological leap that could immediately close the gap between Russia and more advanced economies, as Sputnik did for the Soviet Union. The hyperloop, a kind of train in a tube that can reach speeds of up to 700 mph, fits that dream, and a well-connected Russian businessman has invested in it — only to see the project become embroiled in a lawsuit involving a Silicon Valley startup’s founders and claims of financial mismanagement.

Elon Musk, Tesla’s chief executive, proposed the hyperloop four years ago. This “fifth mode of transport” would involve a system of practically airless tubes through which magnetically levitated pods could carry passengers and cargo. Musk has not set up a company to bring the project to reality, but others have. For example, Hyperloop Transportation Technologies, wants to build a system in Slovakia. Another, Hyperloop One, offered a public demonstration of some elements of its technology in May.

Hyperloop One has seemed the most advanced project, and Russian investors showed an interest from the start. The state-owned Russian Direct Investment Fund took a small stake in the company, but Ziyavudin Magomedov, head of Summa Capital, was the most enthusiastic Russian investor, putting up money for both of the company’s funding rounds.

ON Semiconductor’s new 8 megapixel (MP) KAI-08052 image sensor enhances imaging performance in demanding industrial applications with technology that improves the near-infrared sensitivity of CCD image sensors.

The image sensor provides up to twice the sensitivity in near-infrared wavelengths as the company’s standard Interline Transfer CCD pixel design. This enhanced sensitivity can be critical in applications such as scientific and medical imaging, where samples emit or fluoresce in NIR wavelengths; or in machine vision and intelligent transportation systems (ITS), where NIR illumination is often used to better examine an object or to isolate a vehicle’s license plate.

The new CCD pixel design used extends the electron capture region deeper in the silicon to better capture electrons generated by long wavelength photons. This deeper pixel well improves detection of NIR wavelengths by up to a factor of two depending on the specific wavelength studied.

Elite athletes need never miss an opportunity to train again, even when they’re 40,000 feet above the ground.

A new luxury private plane for sports teams aims to keep athletes in top shape while travelling to and from events, thanks to on-board training facilities including exercise bikes and massage tables.

Russian luxury jet firm Sukhoi unveiled its concept SportJet at the Farnborough International Airshow in Hampshire this week.

Reaction Engines Ltd. announces today the signing of a €10m Development Contract with the European Space Agency, finalizing the UK Government’s £60m commitment.

Reaction Engines Ltd., today announces the signing of a €10m European Space Agency (ESA) contract which will enable the development of a ground based demonstrator of SABRE, a new class of aerospace engine which is highly scalable with multiple potential applications in hypersonic travel and space access.

SABRE is at heart a rocket engine designed to power aircraft directly into space (single-stage to orbit) to allow reliable, responsive and cost effective space access, and in a different configuration to allow aircraft to cruise at high speeds (five times the speed of sound) within the atmosphere.
