Signal Processing

We've long known how the nerve endings in our skin detect cold and swiftly relay the information to our brains, but we haven't understood exactly how it works. Scientists have now solved the puzzle, unlocking the mystery of this temperature pathway.

Researchers at the University of Washington (UW) have created an app they claim can detect sleep apnea with similar accuracy to available methods, potentially removing the need for expensive equipment and overnight hospital stays.

Physicists have discovered a way to use a gallium arsenide nanodevice as a signal processor at “terahertz” speeds that could help end the electron and wires bottleneck for optical communications and computing.

Scientists have created a laser that transmits data via dips to darkness, instead of via pulses of light.
