The world would look radically different without rulers and measuring tapes that fit into a pocket. Carpenters, fashion designers and engineers rely on these trusty tools to check the size of everything from a wooden board to a fabric swatch. But physicists who work with light lack that same convenience for one of the basic measurements of their craft.

They routinely need to measure and compare the frequencies—colors—of the light waves they are using.

Diet alone cannot explain differences in gut bacterial communities

Why do the gut microbiomes of people from industrialized and nonindustrialized regions differ? A study by the Helmholtz Center for Infection Research (HZI) in collaboration with the European Molecular Biology Laboratory (EMBL), the University of Trento (Italy) and the University
