Physics Professor Shawn-Yu Lin Breaks New Ground in Thermal Radiation Revolutionary discovery could advance solar energy conversion

Troy, N.Y. - Nano-photonics expert and physics professor Shawn-Yu Lin has discovered a new type of thermal radiation—in between the two extremes of blackbody radiation and laser light—that could contribute to a cheaper, easier solution for converting sunlight to electricity.

RPI Lighting Experts Study Safer European Headlight Technology

The disconcerting and often dangerous sensation of being blinded by an oncoming driver who failed to turn down high-beam headlights may become a thing of the past, if European headlight technology can pass muster in the U.S. Some testing on the lights is being done at the Lighting Research Center at Rensselaer Polytechnic Institute, where senior researcher John Bullough is examining the so-called "matrix lights" on an Audi A7 luxury sedan.

To sleep, perchance

Screens before bedtime harm sleep. The effect is biggest for teenagers. Mariana Figueiro and her colleagues at the Lighting Research Center at Rensselaer Polytechnic Institute in Troy, New York, studied people aged 15 to 17. Melatonin levels were 23% lower after an hour of looking at a screen. After two hours, they were 38% lower.
