Cover illustration: Twisted X-rays can be used to study helical structures, as shown by Jüstel et al. [Acta Cryst. (2016), A72, 190-196]. Simulations show that the method could be applied to some of the most important structures in biology and a striking number of the structures that are emerging in nanoscience.
