The 2014 Nobel Prize In Physics Goes To The Inventors Of The Blue LED

Congratulations goes out to Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura. Some 20 years ago, they invented the blue light-emitting diode, an energy-efficient and environmentally efficient light source with revolutionary implications. » 10/07/14 1:45pm 10/07/14 1:45pm

Man builds induction-powered LED engagement ring, wins at everything

Here's how to turn a bar of titanium into a ring with LED-illuminated jewels that light up when they're near a power source. One: fall in love. Two: a bunch of other stuff. Three: boom, magic-ring. » 5/23/13 8:10am 5/23/13 8:10am

Improve office productivity by working under fake clouds!

Being outside gives us a sense of freedom and spaciousness, and as far as some German engineers are concerned, that means increased work efficiency. That's why they've invented a "dynamic luminous ceiling" that simulates working outside during a clouding day. » 1/03/12 3:40pm 1/03/12 3:40pm

Engineers have created an LED display you can wear like a contact lens

Thanks to the advent of smart phone technologies, many of us already carry the internet with us everywhere we go. But now, scientists have created the world's first wirelessly powered, computerized contact lens with an integrated LED display. That's right — the same access to information afforded us by the technology… » 11/22/11 11:00am 11/22/11 11:00am

Glowing Bamboo Provides Safe Haven for Alien Landings

The best way to help alien visitors land on Earth would be to provide decent lighting around safe landing zones, figured Sevcan Yardim, a recent graduate from the Middle East Technical University in Ankara. So she got hold of some bamboo — a rarity in Turkey, but great for energy efficiency — laced them with LED light… » 2/26/08 8:20am 2/26/08 8:20am
