U.S. Navy-funded researchers are developing a form of visible light-based communication that transmits data using fast-blinking LEDs rather than Wi-Fi’s familiar radio waves.

They say their plant factories could be used to lure and trap nuisance bugs as an environmentally friendly alternative to pesticides and synthetically produced attractants. Using a multistep process to genetically modify a close relative…
