Akasaki Isamu, Amano Hiroshi, and Nakamura Shuji received their Nobel Prizes in Stockholm this week, and each gave a speech. Akasaki began with a little joke. He said that although the first character in his name meant “red,” he would be talking about blue light. He talked about the importance of choosing the right materials. Amano talked about how he saw his goal from the beginning of his research. Nakamura spoke about how LEDs have helped to save energy. Thanks to their work, the world is a different place now. At this time of year, we can see their LEDs everywhere as Christmas lights.(by Prof. Douglas Jarrell)

Tigers are rare animals. They used to live all over Asia, but now there are fewer than 5,000. In the north, there are about 250 Siberian tigers that live in Russia and northern China. Vladimir Putin, the Russian president, wanted to show that he was interested in saving the tigers. He helped a group of scientists that put some tigers back into the wild in 2011. Now a couple of those tigers are in China eating the goats of Chinese farmers. The Chinese government is probably not very happy, but it doesn’t want to kill the tigers. Instead, it will pay the farmers for their losses.  (by Prof. Douglas Jarrell)
