  • The passing of Gordon Moore, an Intel co-founder, is a good time to reflect on the achievements of the semiconductors industry and how nanomaterials could allow Moore’s law to outlive its formulator.

  • High-energy electrons that collide at a beam splitter repel each other because of strong Coulomb interactions, which could be harnessed for quantum information processing.

  • The implementation of topological antiferromagnetic vortices in information storage devices requires an efficient method of nucleation and a way to control their movement. Here the authors find CuMnAs to be a suitable electrically conducting antiferromagnet host material for topological spin textures.

  • While engineered nanomaterials are relatively new, organisms have been exposed to natural nanoparticles over vast periods of time. Here the authors explore the possibility that common mechanisms of response to nanomaterials may have resulted from a long evolutionary exposure history to natural nano-sized matter.
