[Shane Ormonde] recently learned how to measure distance using just a webcam, a laser, and everyone’s favorite math — trigonometry. Since then he’s thrown the device onto a stepper motor, and now has ...

We've cut the cord for communication, thanks to Bluetooth and Wi-Fi, but charging our little pocket supercomputers still takes a tether. Judging by the range of wireless charging technologies in the ...

An energy-efficient alternative to the laser no longer requires a deep freeze. The first plug-in, room-temperature polariton laser, reported in the June 13 Physical Review Letters, could soon find its ...

Researchers from the University of Washington have devised a new way to charge a smartphone from across the room using lasers. The team says that the method of charging is safe and uses a narrow ...

Being able to see inside a closed room was a skill once reserved for super heroes. But researchers at the Stanford Computational Imaging Lab have expanded on a technique called non-line-of-sight ...
