Electrical engineers at Duke University have created the world's first electromagnetic metamaterial made without any metal. The device's ability to absorb electromagnetic energy without heating up has direct applications ...
Anyone who has stood in confusion in the light-bulb aisle (and that's most of us) knows that technology and the push to save energy are continuing to flip the script on home lighting options.
The intensity of artificial lighting has been shown to have a range of effects on our mood and our ability to concentrate. New research explores the color of lighting and its effect on our cognitive performance. The study, ...
Traditional light bulbs, thought to be well on their way to oblivion, may receive a reprieve thanks to a technological breakthrough.
Most Christmas lights, DVD players, televisions and flashlights have one thing in common: they're made with light emitting diodes (LEDs). LEDs are widely used for a variety of applications and have been a popular, more efficient ...
For consumers who are still bemoaning the phaseout of incandescent light bulbs, hate the harsh CFLs and can't figure out LEDs, another option may be on the horizon - a new kind of bulb is slated to hit store shelves this ...
Highly efficient, light-emitting diodes (LEDs) could slash the world's electricity consumption. They are already sold in stores, but more widespread adoption of the technology has been hindered by high costs due to limited ...
Led by Young Duck Kim, a postdoctoral research scientist in James Hone's group at Columbia Engineering, a team of scientists from Columbia, Seoul National University (SNU), and Korea Research Institute of Standards and Science ...
Technology developed by the University of Cincinnati and industry partners can do something that neither blinds nor existing smart windows can do. This patent-pending research, supported by the National Science Foundation, ...
A congressional deal to finance the government chips away at some Obama administration energy and environmental programs, but leaves largely intact the president's plans on global warming—at least until Republicans take ...
