Researchers have shown how small random patches of disordered, frozen electric charges can make a difference when they are scattered on surfaces that are overall neutral. These charges induce a twisting force that is strong enough to be felt as far as nanometers or even micrometers away. These results could help scientists to understand phenomena that occur on surfaces such as those of large biological molecules.
