Scientists have successfully transmitted a text message via the world’s first wireless molecular network in a breakthrough that could lead to better methods of sending data in challenging underground or underwater environments where electromagnetic waves cannot be used. To send their message, researchers at the University of Warwick in the UK and the York University in Canada … [Read more...]
Optical “Tuning Fork” May Help Stabilize Light Frequencies for Better Electronics
Researchers at the California Institute of Technology (Caltech) have developed an optical “tuning fork” device they say could help improve high-speed communications, navigation and remote sensing by stabilizing the signals of high-quality lasers and the electrical currents needed to power electronics. "When you're tuning a piano, a tuning fork gives a standardized pitch, or … [Read more...]
