In recent years optical fibers have served as sensors to detect changes in temperature, like a thermometer, and pressure, like an artificial nerve. This technique is particularly useful in structures such as bridges and gas ...
In the blink of an eye, a massive star more than 2 billion light-years away lost a million-year-long fight against gravity and collapsed, triggering a supernova and forming a black hole at its center.
Researchers and engineers have long sought ways to conceal objects by manipulating how light interacts with them. A new study offers the first demonstration of invisibility cloaking based on the manipulation of the frequency ...
Traffic signals give priority to motor vehicles over pedestrians. This inequality undermines many of the stated goals of transport, health and environment policy.
Yale scientists have created a new type of silicon laser that uses sounds waves to amplify light. A study about the discovery appears June 8 in the online edition of the journal Science.
Similar to the eye of a hurricane, physicists of research institute AMOLF, the University of Amsterdam and the University of Texas at Austin, have captured light in the eye of an optical vortex. The research will be published ...
Researchers at Duke University have built the first metal-free, dynamically tunable metamaterial for controlling electromagnetic waves. The approach could form the basis for technologies ranging from improved security scanners ...
Eight months ago, the detection of gravitational waves from a binary neutron star merger had us and other astronomers around the world rushing to observe one of the most energetic events in the universe.
Researchers at the National Institute of Standards and Technology (NIST) have created a chip on which laser light interacts with a tiny cloud of atoms to serve as a miniature toolkit for measuring important quantities such ...
The shower of electrons bouncing across Earth's magnetosphere, commonly known as the Northern Lights, has been directly observed for the first time by an international team of scientists. While the cause of these colorful ...
