Make Magazine has produced a great documentary on the history of LEDs. It turns out the Light Emitting Diode was discovered by accident, during an experiment at Marconi labs. The documentary shows you how to recreate that initial experiment yourself, if you are so inclined. Maybe if we all get together, we can make an LED display bigger than the one in front of that Walgreens in Times Square, NYC.

German researchers believe that they have found the secret to eternal youth, LEDs. Their study found that exposure to LED light at high intensities and over a several week period resulted in the elimination of wrinkles.

I can see artificial LED tanning salons popping up everywhere attracting hordes of people lusting to have their skin revitalized. I guess that would be better than plastic surgery, no?

The Rockefeller Center Christmas tree will be using a lot less energy this season as it is going "greener" — with energy-saving lights replacing old-fashioned bulbs this year.

NYC Mayor Michael Bloomberg announced yesterday that the tree will be lit up with 30,000 LED lights for the first time and this will reduce energy consumption from 3,510 kilowatt hours per day to just 1,297 — a savings that, as the AP points out, is roughly equivalent to the amount of electricity consumed by a typical 2,000-square-foot house in a month.
