(Phys.org)—A small team of researchers from the University of California and the University of Washington has found that not all of the color-sensing cells in the back of the eyeball actually help us to see color. Instead, ...
Replacing traditional light bulbs with light-emitting diodes (LEDs) could take a significant bite out of global energy consumption. But making white LEDs isn't completely benign or budget friendly. To help reduce the environmental ...
