Perspectives

Oxidation states and ionicity    pp958 - 964
Aron Walsh, Alexey A. Sokol, John Buckeridge, David O. Scanlon & C. Richard A. Catlow
doi:10.1038/s41563-018-0165-7

This Perspective explores the history and usage of the concept of oxidation state, its relation to atomic charge and bonding, and opportunities that arise from applying this analysis to systems with mixed valence or correlated electrons.

Interparticle hydrogen bonding can elicit shear jamming in dense suspensions    pp965 - 970
Nicole M. James, Endao Han, Ricardo Arturo Lopez de la Cruz, Justin Jureller & Heinrich M. Jaeger
doi:10.1038/s41563-018-0175-5

Dense suspensions of hard particles readily display discontinuous shear thickening under shear but not reversible shear jamming. Here it is shown that the formation of interparticle hydrogen bonds is crucial for the shear jamming of these suspensions.

Therapeutic treatment of Zika virus infection using a brain-penetrating antiviral peptide    pp971 - 977
Joshua A. Jackman, Vivian V. Costa, Soohyun Park, Ana Luiza C. V. Real, Jae Hyeon Park et al.
doi:10.1038/s41563-018-0194-2

The Zika virus infects the central nervous system and results in severe brain malformation. An amphiphatic peptide is now shown to penetrate the blood–brain barrier, reducing viral loads due to its activity against Zika and other mosquito-borne viruses.
