Camera-based visibility takes over as Polestar redesigns airflow
First look: The 2026 Polestar 4 removes a feature that has defined automotive design for more than a century: the rear window. In its place, the vehicle uses cameras and sensors to provide rearward visibility, a move that is dividing opinion.
Forward-looking: A European research team involving scientists from DESY and Hamburg University of Technology have unveiled a newly demonstrated triboelectric nanogenerator that produces electricity by pushing water in and out of nanoporous silicon. Their work marks a significant step toward battery-free power for sensors and other low-power devices.
Why it matters: Ikea is a brand universally known for cheap, ready-to-assemble furniture, home appliances, and other home accessories. The company is now trying to put its mark on the smart home business as well, bringing the same affordable and minimalistic approach to the hi-tech monitoring market.
