Molecules are never still. Driven by thermal energy, they are constantly moving through space, while their individual parts also rotate relative to one another. Scientists at IOCB Prague have now shown that random motion within a molecule can be dramatically suppressed. Using light, they can slow down the relative rotation of two different parts of a single molecule by up to five orders of magnitu
