All of the Lights

Elon Musk's new Tesla, the Nobel Prize-winning blue diode, skateboarding sculptor Stefan Janoski and more in our weekly look at the web

The Nobel Prize winners have been announced for 2014 and, in the category of physics, a trio of Japanese scientists (one who is now a US citizen) have been honored for inventing the blue light-emitting diode 20 years ago. While green and red diodes have been around for around 50 years, it took much longer to develop a diode that could emit blue light—which was the final ingredient needed to create white light (a combination of the three colors). Congratulations and thank you to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura for making energy-efficient LED lamps possible.
