Accelerator-on-chip Researchers at Stanford University and SLAC National Accelerator Laboratory created an electron-accelerator-on-chip. While the technique is much less powerful than standard particle accelerators, it can be much smaller. It relied upon an infrared laser to deliver, in less than a hair’s width, the sort of energy boost that takes microwaves many feet. The team carved ... » read more

When self-driving cars collide As self-driving car technology develops and evolves, it is inevitable that there will be collisions while the tech matures. “What can we do in order to minimize the consequences?” asks Amir Khajepour, a professor of mechanical and mechatronics engineering at the University of Waterloo. “That is our focus.” The first rule for the autonomous vehicle (... » read more

Using bandwidth like a fish Researchers from the University of Georgia developed a method to make fuller use of wireless bandwidth, inspired by a cave-dwelling fish's jamming avoidance response. Eigenmannia fish live in complete darkness, sensing their environment and communicating through emitting an electric field. When two fish emit signals at similar frequencies they can interfere with ... » read more

Atomristors for thin memory Engineers at The University of Texas at Austin and Peking University developed a thin memory storage device with dense memory capacity. Dubbed "atomristors," the device enables 3-D integration of nanoscale memory with nanoscale transistors on the same chip. "For a long time, the consensus was that it wasn't possible to make memory devices from materials that were... » read more

Power converter for IoT At the International Solid-State Circuits Conference, researchers from MIT presented a new power converter that is efficient at a wide range of currents, which could be a boon for IoT sensors that have variable power requirements. The device maintains its efficiency at currents ranging from 500 picoamps to 1 milliamp, a span that encompasses a 200,000-fold increase in... » read more
