Isamu Akasaki and Hiroshi Amano, from Japan’s University of Nagoya, and Shuji Nakamura, from the University of California, have been awarded the Nobel Prize in physics for their invention of the blue light-emitting diode (LED).
As you might know, white light can be created by combining red, green, and blue colors. We have been playing with red and green LEDs for a while but there were no blue ones. Then blue LED was invented more than 20 years ago by Akasaki, Amano and Nakamura and they were able to create a white light-emitting LED lamp.

According to the awarding committee:
The LED lamp holds great promise for increasing the quality of life for over 1.5 billion people around the world who lack access to electricity grids: due to low power requirements it can be powered by cheap local solar power.
In case you missed it, John O’Keefe, a British-American researcher, and Norwegian couple Edvard and May-Britt Moser were awarded the Nobel Prize in medicine for “their discoveries of cells that constitute a positioning system in the brain.” The prizes in chemistry, literature, economics and the Nobel Peace Prize will be announced by the committee later this week.
