That’s a weird one, but it’s true. Some geeky researchers (can’t imagine someone else to spend time on that one) managed to “make” LEDs from salmon sperm which is considered a waste product of the fishing industry. Professor Andrew Steckl of the University of Cincinnati, used the DNA found in salmon sperm to make LEDs more intense and called them BioLEDs. Steckl is developing them with the help of the Air Force (serious).

If it’s privacy that you want and you don’t like that surveillance camera to see you there is a solution. You have to use an array of bright infrared LED devices that would “blind” the CCDs in security cameras while the face is monitored by a light ball over. Until the German guy showcased his new URA / FILOART device (yes, weird name) I didn’t knew that the IR LEDs could be used for something better than improving night vision.

This is good news but I just don’t want thieves to use these “inventions” to help them out.
