For the first time, a study has shown that residual movements continue to animate proteins inside a crystal and that this movement 'blurs"´' the structures obtained via crystallography. The study stresses that the more these residual movements are restricted, the better the crystalline order.

Perovskite solar cells are cheaper to make than traditional silicon cells and their electricity conversion efficiency is improving rapidly. To be commercially viable, perovskite cells need to scale up from lab size. Researchers report a method for making perovskite cells larger while maintaining efficiency.

Read moreThe quest to control and understand the intrinsic spin of electrons to advance nanoscale electronics is hampered by how hard it is to measure tiny, fast magnetic devices. Applied physicists offer a solution: using heat, instead of light, to measure magnetic systems at short length and time scales.
