EyeDAR Streetlight Radar Expands Self-Driving Cars' View

Rice University researchers developed EyeDAR, a compact orange radar sensor mounted on streetlights that acts as an external set of eyes for autonomous vehicles, maintaining detection in fog, rain, and low light. Using a 3D-printed Luneburg lens and analog computing, EyeDAR conveys sensing data to vehicles, extending their view while cutting reliance on onboard computing; in tests it resolved target directions 200 times faster than existing digital radar, suggesting potential city-wide deployment across stop signs and traffic signals to improve safety.

Water wave analogue computer predicts chaotic future.

Researchers have built a proof-of-concept computer that uses running water instead of traditional logical circuitry processors to forecast future events via an approach called "reservoir computing." The computer uses solitary waves to process data at a higher speed and can forecast financial markets and certain kinds of human activity. The researchers plan to miniaturize the computer as a microfluidic processor, which could bring data science and machine learning to rural and remote communities worldwide.
