What is the origin of these arousals? Scientists have discovered that brief arousals are probably triggered by the intrinsic electrical noise from wake-promoting neurons (WPN) in the brain. Their research reveals a previously unrecognized neurophysiological mechanism that links sleep arousals with temperature regulation, and may also provide an important new link between temperature and Sudden […]

Researchers have built a new optical device no bigger than the edge of a coin. The device includes a photovoltaic cell that is powered by infrared light and emits blue light. Using infrared light allows the device to be implanted several centimeters deep into the body, while the emission of blue light can be used […]

In a groundbreaking new study, researchers used a customized, low-cost 3-D printer to print electronics on a real hand for the first time. The technology could be used by soldiers on the battlefield to print temporary sensors on their bodies to detect chemical or biological agents or solar cells to charge essential electronics.
