Tohoku University
From this day forward, all math professors should be called “fantasistas of number theory.”
Earlier this year Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura won the Nobel Prize in Physics for their development of an efficient blue light-emitting diode (blue LED).
It was a well-deserved victory for the Japanese scientists whose invention continues to impact our lives in ways we often don’t even notice. It could be in the display you’re looking at right now or it could be helping some of the millions of people in parts of the world without electrical infrastructure get affordable lights for their homes.
And now in a report published in Scientific Reports, a team of researchers from Tohoku University have found a new use for blue LED. When used in the right frequency it can be an effective, safe, clean, and cheap way to kill insects. For the first time, they showed that visible light around the blue part of the spectrum is lethal to insects such as mosquitoes and fruit flies.
On 15 July, Tohoku University sent eviction notices to all 105 residents of Meizenryo, a student-governed dormitory in Sendai. The school claims that the students violated their “promise to abstain from alcohol.”
Although asking a building full of college students not to drink is like asking a building full of tigers not to scratch the furniture, the school is taking a hardline stance of incredulousness at their behavior. Nevertheless, students are appealing saying that not everyone in the dorm drinks and some should be allowed to stay.
