Lasers, LEDs and light sources are devices that create light. LEDs (light emitting diodes) convert an electrical current into light using spontaneous emission in optically active semiconductors.

We’ve all seen insects swarm towards a source of light at night like, well, like a moth to a flame. Notably, insects seem to ...

A novel paper is widening understanding of how species interact within ecosystems via the so-called 'Internet of Nature.' The paper reveals that species not only exchange matter and energy but also ...

The findings give hope for a new type of light source for quantum computing and quantum communication. Intense research on carbon nanotubes has uncovered numerous intriguing properties ...

Lots of different sources produce light. Earth's main source of natural light is the Sun. At night, moonlight is created by the moon reflecting the Sun's light. This allows us to see at night ...

Results of the new observations, presented in a research paper published March 28 on the arXiv preprint server, shed more light on the persistent nature of this source. X-ray binaries are composed ...
