Engineers create nanophotonic structures that can compute using “light and waves”
Analog computing might get a new lease on life thanks to metamaterials that control electromagnetic waves. Researchers from the University of Pennsylvania (UPenn) developed a metamaterial whose tiny structures manipulate light to solve mathematical equations. “Photonic calculus” encodes parameters into the properties of an electromagnetic wave. Once the wave passes through the metamaterial, its properties get altered by nanostructures. The modified electromagnetic wave serves […]

“HyQReal” robot dog is strong enough to pull a 3-TON plane over 30 feet
The latest in a long line of Italian emergency robots has demonstrated its mechanical strength and surefooted stance by towing a three-ton business jet across a concrete tarmac. In a recently released video recorded at Genoa Airport in Genoa, Italy, the HyQReal robot pulled a Piaggio P180 Avanti passenger jet over a distance of 33 […]

This updated jumping robot can be used to develop smaller robots for aid-and-rescue missions, suggest scientists
Salto is a robot that stands less than a foot tall, but it jumps more than three times its height. Its small size even lets it pass through cramped spaces to reach people trapped under rubble. Developed by a team from the University of California (UC), Berkeley in 2016, Salto’s capabilities have grown in leaps and bounds over the […]

NASA designs suits to help astronauts deal with microbes in Martian dust (while still denying discovery of microbial life on Mars)
Researchers have not yet determined if even the most simplistic form of alien life exists on Mars. But just in case, NASA is designing spacesuits that will keep astronauts safe from both potential Martian microbes and actual dust. The crews of the first three Apollo missions that landed on the moon went through quarantine protocol […]

Study: Light and nanotech can prevent bacterial infections caused by medical implant surgeries
Spanish researchers combined nanotechnology and photonics to improve the effectiveness of medical meshes in surgical implants. Powered by light, nanoparticles killed any disease-causing bacteria that might cause a dangerous infection in the mesh. Medical meshes help a surgery patient recover faster after an operation that removed, repaired or replaced damaged tissue in his body. A […]

NASA’s Star Wars-inspired Astrobee will assist astronauts, boost productivity and maintain spacecraft
NASA’s newest robots called Astrobee resemble cubes far more than bees. But the American space agency believes that the autonomous flying robots will prove as busy as their insect namesake. On Earth, bees enjoy a reputation for working hard and nonstop. Their robotic, space-going counterparts will share those qualities by supporting human astronauts in space and […]

Don’t text and drive: Police introduce unique device that digitally spots offenders who use their phones while driving
The UK police have recently begun deploying a machine that keeps a lookout for any driver who uses his phone while driving. If it spots any instance, it flashes a warning at the distracted driver to stop doing such a careless thing. Intended to decrease the chances of avoidable deaths caused by vehicular accidents, the device […]

UK troops will soon have palm-sized drones for monitoring enemies on the battlefield
The British Army is getting additional electronic eyes in the sky in the form of drones that fit in the palm of a soldier’s hand. Hundreds of the “Black Hornet” surveillance drones will eventually replace human troops in the dangerous roles of surveillance and reconnaissance on the battlefield. Developed by the UK Ministry of Defense (MOD), […]

Research team uses metamaterials to create an “acoustic telescope” that can transmit messages to an individual in a crowd
A recently developed “acoustic telescope” uses light-manipulating techniques to transmit and pick up sounds over long distances. Acoustic metamaterials make it possible for the device to target people at a distance and project sounds into their heads. Academics from the University of Sussex and their colleagues at the University of Bristol demonstrated how they used acoustic […]

Physicists develop new material that could be used for “high-efficiency, lower-cost solar cells”
Researchers have not yet solved the biggest weakness of solar panels – their inability to produce power when there is no steady source of bright light. However, they were happy to announce that they have increased the efficiency of perovskite solar cells to take advantage of the limited daylight hours. University of Toledo (UT) researcher Dr. […]
