A floating solar device may soon help millions of people worldwide who don’t currently have access to clean drinking water. Scientists in the U.K. have developed technology that turns contaminated water into purified water and clean hydrogen fuel simultaneously.

Thanks, in part, to an electro-optic setup, a team of researchers led by the U.S. National Institute of Standards and Technology has created a dual-frequency comb system that can detect specific molecules in a sample as quickly as every 20 nanoseconds.

Intent on answering some fundamental questions about the interactions between light and matter, researchers in England are exploring how vibrations within a molecule and the subsequent emission of sound interact with light, and whether that retains quantum effects.
