Ford has developed a prototype shopping cart that brakes all on its own, called the “Self-Braking Trolley,” which takes a page from vehicle technology that helps drivers avoid obstacles. In particular, the company used their pre-collision assist tech, found in most Ford car models, as inspiration. The system detects other vehicles, pedestrians, and cyclists while…

A tiny, portable radar device could allow visually impaired people, or unmanned moving devices to detect objects in real time. Radar technology has been used for decades in aviation, defense and speed-camera technology. Now, a team at KAUST, in collaboration with scientists at the VTT Technical Research Center of Finland, have created a compact, low-cost…

On its final flyby of Saturn’s largest moon in 2017, NASA’s Cassini spacecraft gathered radardata revealing that the small liquid lakes in Titan’s northern hemisphere are surprisingly deep, perched atop hills and filled with methane.  The new findings, published April 15 in Nature Astronomy, are the first confirmation of just how deep some of Titan’s lakes…

In April 2018, Starship Technologies started transporting groceries to residents in Milton Keynes, U.K., from a co-op food store. A year later, the company has announced it has made more than 50,000 commercial deliveries with its autonomous robots. In total, the robo-deliverers have travelled more than 200,000 miles in more than 100 cities worldwide. Lex…

Supercell thunderstorms are terrifying natural marvels that carry high risks of lethality and devastation. To improve prediction and reduce “false alarm” tornado warnings, researchers are planning an investigation centered on radar and unmanned aircraft systems (UAS) called the Targeted Observation by Radars and UAS of Supercells (TORUS). The study will gather intel on the supercell’s…

Among the urban traffic in Hamburg, Germany, will be a fleet of five e-Golf automated test vehicles from Volkswagen Group Research.  According to the company, it will be “the first time Volkswagen has begun to test automated driving to Level 4 at real driving conditions in a major German city.” Hamburg is currently undergoing a…

Radar technologies were originally designed to identify and track airborne military targets. Today they’re more often used to detect motor vehicles, weather formations and geological terrain. Until now, scientists have believed that radar accuracy and resolution are related to the range of frequencies or radio bandwidth used by the devices. But a new Tel Aviv…

On Nov. 13, 1985, the Nevado del Ruiz volcano in the Andes – about 80 miles west of Bogota, Colombia – erupted, sending a pyroclastic flow down its mountainside. The heat melted the snow at an elevation of more than 17,000 feet, and volcanic ash muddied the resulting water – called lahar – that rushed…
