An almost negligible proportion of a few per million consists of "heavy water," in which the hydrogen atoms (H) are replaced by deuterium atoms (D). Deuterium has one ...

A collection of objects just 120 light-years away is a truly gob-smacking ... but not heavy enough for the hydrogen fusion we ...

About 50km (30 miles) north of Beijing’s city centre, construction is wrapping up on what is expected to be the world’s brightest X-ray light source, slated to switch on later this year to ...

An almost negligible proportion of a few per million consists of "heavy water," in which the hydrogen atoms (H) are replaced by deuterium atoms (D). Deuterium has one more neutron in its nucleus ...

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.

Lorex is now shipping a new Wi-Fi pan/tilt security camera with an integrated LED light source. While it’s not an entirely new idea, the Lorex 2K Wi-Fi Lightbulb Camera draws power from a ...

(c) Diamond Light Source Known as a synchrotron, it’s a large particle accelerator, but rather than smashing atoms together to study them, as is done at CERN, here they are used to generate powerful ...

A research group has manipulated light through its interaction with a metal surface so that it exhibits entirely new properties. A research group at the University of Stuttgart has manipulated ...
