Halide perovskites are cheap, versatile and remarkably efficient as both solar cells and light emitters.
Often presented as one of the best ways to save energy, eco-efficiency often proves to be less effective than one might think.
Encouraging people to buy LED bulbs is not a long-term solution. We need lighting which is kind to the planet and our health.
A lighting revolution is underway across Africa that's occurred largely without government or donor involvement.
Layering substances like graphene in new ways could help us to build quantum computers or transmit electricity over long distances.
LED lights can actually improve upon the sun and help grow plants in space. A Canadian team of researchers is helping to refine and perfect LED technology.
The CO2 we produce when we put up buildings is large and virtually unregulated.
That flicker in the corner of your eye isn't your imagination.
New research shows the insects use the brightness of different stars to work out which direction to go.
The American Medical Association (AMA) issued guidelines for communities to reduce harmful effects of LED streetlights. A medical researcher explains what can go wrong.
