The Istanbul Metropolitan Municipality is working on an artificial intelligence (AI) project to ease the city’s notorious traffic jams, daily Milliyet has reported.
“By analyzing images from junctions, the system will activate traffic lamps and turn them green in a short time to ease traffic flow,” said Esat Temimhan, the director of Istanbul IT and Smart City Technologies (İSBAK), an sub unit of the municipality.
The AI system has started in two pilot regions, he said.
Scientists in Australia have developed a process for calculating the perfect size and density of quantum dots needed to achieve record efficiency in solar panels.
Quantum dots, man-made nanocrystals 100, 000 times thinner than a sheet of paper, can be used as light sensitisers, absorbing infrared and visible light and transferring it to other molecules.
This could enable new types of solar panels to capture more of the light spectrum and generate more electrical current, through a process of ‘light fusion’ known as photochemical upconversion.
Researchers at Chalmers University of Technology, with collaborators at Technische Universität Berlin, have demonstrated the shortest wavelength ever reported of a vertical-cavity surface-emitting laser (VCSEL). This can pave the way for future use in, for example, disinfection and medical treatment. The results were recently published in the scientific journal ACS Photonics.
“Although there is still much work to be done, especially to enable electrically driven devices, this demonstration provides an important building block for the realization of practical VCSELs covering the major part of the UV spectral range,” says Filip Hjort, Ph.D. student at the Photonics Laboratory at MC2 and first author of the article.
A vertical-cavity surface-emitting lasers (VCSEL) is a compact semiconductor laser and has seen widespread application in, for example, facial recognition in smartphones and for optical communication in data centers. So far, these lasers are only available commercially with red and infrared wavelengths, but also other visible-emitting VCSELs, that could find applications in adaptive headlamps for cars or projection displays, will soon be commercialized.
Scientists in China claim to have built a hypersonic jet engine—called “sodramjet”—that can fly at 16 times the speed of sound. This means that an aircraft kitted out with such engines could fly anywhere in the world in two hours, according to the scientists. The test flight of a prototype was carried out in a wind tunnel in Beijing, China, and displayed excellent thrust, fuel efficiency, and operational stability. Led by Professor Zonglin Jiang of the Chinese Academy of Sciences’ Institute of Mechanics, the team’s findings were published in Chinese Journal of Aeronautics on Saturday.
Scientists in China have tested a prototype sodramjet engine in a hypersonic wind tunnel at nine times the speed of sound. Check it out here!
Google and its American internet peers are steadily amping up their investment in India, latching onto the only other country with a billion-plus population after getting shut out of China. From Amazon.com Inc. to Facebook Inc., they’re hoping to get in on the ground floor of what they envision as a smartphone and online commerce boom that could eventually create a market to rival the world’s No. 2 economy.
Google investments helped create India’s two youngest technology unicorns: a pair of startups that feed personalized news and entertainment to the world’s fastest-growing smartphone population.
Raise your hand if you ever wanted to get beamed onto the transport deck of the USS Enterprise. Maybe we haven’t reached the point of teleporting entire human beings yet (sorry Scotty), but what we have achieved is a huge breakthrough towards quantum internet.
Led by Caltech, a collaborative team from Fermilab, NASA’s Jet Propulsion Lab, Harvard University, the University of Calgary and AT&T have now successfully teleported qubits (basic units of quantum info) across almost 14 miles of fiber optic cables with 90 percent precision. This is because of quantum entanglement, the phenomenon in which quantum particles which are mysteriously “entangled” behave exactly the same even when far away from each other.

The world’s first robotic kitchen is officially launched this month. The Moley Kitchen, created by British technology company, Moley Robotics, is a fully automated unit that prepares freshly cooked meals at the touch of a button. It consists of cabinets, robotic arms, a motion capture system, a connected graphical user interface with access to a library of recipes, and a full set of kitchen appliances and equipment, optimised for both robot and human use.
The Moley Kitchen – first revealed publicly in April 2015 – is the product of six years of research and development by an international team of 100 engineers, product and luxury interior designers and three award-winning chefs.
At the heart of this new technology are two robotic arms featuring fully articulated ‘hands’, developed in collaboration with world-leading German robotics company SCHUNK. Following 11 exhaustive development cycles, they can now reliably reproduce the movements of human hands. This means the robot can retrieve ingredients from the smart fridge, adjust hob temperature, use the sink to fill pans and pour, mix and plate up just as a human cook would. The robot even cleans up after itself.
