Theoretical physicist Ali Naji from the IPM in Tehran and the University of Cambridge, UK, and his colleagues 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, about to be published in EPJ E, could help to understand phenomena that occur on surfaces such as those of large biological molecules.

A new method to reveal the structure of proteins could help researchers understand biological molecules – both those involved in causing disease and those performing critical functions in healthy cells.
