Where the information comes from: In the experimental part of the work, the researchers placed Teflon objects (orange cylinders) in a waveguide with a rectangular cross-section. They then injected an ...

Much of what we know about the Universe comes from using telescopes to collect and study the electromagnetic waves produced by astronomical objects. These waves can be distorted and absorbed as they ...

Whenever any two things in the Universe interact at the same location in spacetime, one thing always remains true about that interaction: it conserves energy. But what if one of those things is an ...

RESEARCH TRIANGLE PARK, N.C. -- Researchers working on an Army-funded project have developed an algorithm to simulate how electromagnetic waves interact with materials in devices to create equipment ...

Nanoscale devices present a unique challenge to any optical technology -- there's just not enough room for light to travel in a straight line. As light waves are pressed through surfaces only a few ...

The LIGO/VIRGO/KAGRA collaboration searches the universe for gravitational waves produced by the mergers of black holes and neutron stars. It has now announced the detection of a signal indicating a ...

Gravitational waves are ripples in the fabric of space. Waves that originated in the early universe could carry important information about the phenomena that occurred there. When you purchase through ...

Cells at the bottom of a liquid medium begin levitating, then hovering at a particular height. With no physical contact, an ...
