Julienne doi:10.1038/s41567-018-0260-3 A little bit of everything    pp874 - 875 Christian R. Ast doi:10.1038/s41567-018-0258-x Topology on a breadboard    pp875 - 877 Ling Lu doi:10.1038/s41567-018-0235-4 Super spins    pp877 - 878 Joshua Folk doi:10.1038/s41567-018-0182-0 Wrinkled clean    pp878 - 879 Haim Diamant doi:10.1038/s41567-018-0212-y United in a monolayer    pp879 - 880 Alexander W. Holleitner & Paul B. Seifert doi:10.1038/s41567-018-0196-7 Letters   Observation of Feshbach resonances between alkali and closed-shell atoms    pp881 - 884 Vincent Barbé, Alessio Ciamei, Benjamin Pasquiou, Lukas Reichsöllner, Florian Schreck et al. doi:10.1038/s41567-018-0169-x Magnetically tunable scattering resonances between strontium and rubidium atoms are observed in an ultracold experiment, opening the door to exploring quantum many-body physics with new designed molecules.   Strong coupling between photons of two light fields mediated by one atom    pp885 - 889 Christoph Hamsen, Karl Nicolas Tolazzi, Tatjana Wilk & Gerhard Rempe doi:10.1038/s41567-018-0181-1 By coupling photons in two distinguishable modes to separate transitions of a single atom, strong correlations between photons are created. The technique makes all-optical switching and sensing possible at the single-photon level.   Laser cooling of optically trapped molecules    pp890 - 893 Loïc Anderegg, Benjamin L. Augenbraun, Yicheng Bao, Sean Burchesky, Lawrence W. Cheuk et al. doi:10.1038/s41567-018-0191-z Laser cooling of optically trapped diatomic molecules CaF to sub-Doppler temperatures has been achieved. The technique provides an alternative approach towards the production of ultracold polar molecules.   Maximal spontaneous photon emission and energy loss from free electrons    pp894 - 899 Yi Yang, Aviram Massuda, Charles Roques-Carmes, Steven E. Kooi, Thomas Christensen et al. doi:10.1038/s41567-018-0180-2 Calculating the amount of radiation that can ultimately be extracted from free electrons near an arbitrary material structure is a challenge. Now, an upper limit to the spontaneous photon emission of electrons is demonstrated, regardless of geometry.   Electrically switchable Berry curvature dipole in the monolayer topological insulator WTe2    pp900 - 906 Su-Yang Xu, Qiong Ma, Huitao Shen, Valla Fatemi, Sanfeng Wu et al. doi:10.1038/s41567-018-0189-6 Optoelectronic experiments show that a monolayer of WTe2 is a material that simultaneously has topological electronic states and electron wavefunctions with a dipole in their Berry curvature.   Long-distance spin transport through a graphene quantum Hall antiferromagnet    pp907 - 911 Petr Stepanov, Shi Che, Dmitry Shcherbakov, Jiawei Yang, Ruoyu Chen et al. doi:10.1038/s41567-018-0161-5 Spins are transmitted over a distance of 5 μm through a piece of antiferromagnetic graphene. This shows that graphene can be a platform to explore the fundamental physics of spin transport in antiferromagnets for application in spintronics.   Pair-breaking quantum phase transition in superconducting nanowires    pp912 - 917 Hyunjeong Kim, Frédéric Gay, Adrian Del Maestro, Benjamin Sacépé & Andrey Rogachev doi:10.1038/s41567-018-0179-8 Transport measurements performed on MoGe superconducting nanowires reveal a quantitative agreement with quantum critical behaviour driven by a pair-breaking mechanism.   Articles   Higher-order topology in bismuth    pp918 - 924 Frank Schindler, Zhijun Wang, Maia G. Vergniory, Ashley M. Cook, Anil Murani et al. doi:10.1038/s41567-018-0224-7 The study of the band structure and crystal symmetry of the semimetal bismuth indicates that this material is a higher-order topological insulator hosting robust one-dimensional metallic states on the hinges of the crystal.   Topolectrical-circuit realization of topological corner modes    pp925 - 929 Stefan Imhof, Christian Berger, Florian Bayer, Johannes Brehm, Laurens W. Molenkamp et al. doi:10.1038/s41567-018-0246-1 The realization of a two-dimensional quadrupole topological insulator—featuring gapless corner states but an otherwise insulating bulk and edge—establishes electrical circuits as a versatile platform for implementing topological band structures.   Even-denominator fractional quantum Hall states at an isospin transition in monolayer graphene    pp930 - 935 A. A. Zibrov, E. M. Spanton, H. Zhou, C. Kometter, T. Taniguchi et al. doi:10.1038/s41567-018-0190-0 Quantum Hall states are observed in monolayer graphene at even-denominator fractional filling of the lowest Landau level. This is linked to transitions in the spin and valley structure of the ground state.   Observation of two independent skyrmion phases in a chiral magnetic material    pp936 - 941 A. Chacon, L. Heinen, M. Halder, A. Bauer, W. Simeth et al. doi:10.1038/s41567-018-0184-y A new type of skyrmion is identified in the chiral magnetic material Cu2OSeO3 at low temperature. This is the first time that a single material has been shown to exhibit more than one distinct skyrmion phase.   Constant-pressure sound waves in non-Hermitian disordered media    pp942 - 947 Etienne Rivet, Andre Brandstötter, Konstantinos G. Makris, Hervé Lissek, Stefan Rotter et al. doi:10.1038/s41567-018-0188-7 Perfect transmission of sound waves through a strongly disordered environment is demonstrated using a set of speakers that provide exactly the right input to counteract scattering by the disorder. These principles can also be applied to light.   Topography-driven surface renewal    pp948 - 953 Luka Pocivavsek, Joseph Pugar, Robert O’Dea, Sang-Ho Ye, William Wagner et al. doi:10.1038/s41567-018-0193-x Natural surfaces better their synthetic counterparts at coping with biofouling. A characterization of topography-induced delamination reveals a mechanism whereby elastic energy drives the crack propagation that facilitates surface renewal.   Verticalization of bacterial biofilms    pp954 - 960 Farzan Beroz, Jing Yan, Yigal Meir, Benedikt Sabass, Howard A. Stone et al. doi:10.1038/s41567-018-0170-4 Biofilms of rod-shaped bacteria can grow from a two-dimensional layer of founder cells into a three-dimensional structure with a vertically aligned core. Here, the physics underlying this transition is traced down to the properties of individual cells.   Neutrino interferometry for high-precision tests of Lorentz symmetry with IceCube    pp961 - 966 M. G. Aartsen, G. C. Hill, A. Kyriacou, S. Robertson, A. Wallace et al. doi:10.1038/s41567-018-0172-2 A violation of Lorentz symmetry would represent a fundamental departure from the physics of the standard model. Searching for anomalous neutrino oscillations, the IceCube collaboration reports no violation, and puts stringent bounds on its existence.   Amendments & Corrections   Publisher Correction: Long-distance spin transport through a graphene quantum Hall antiferromagnet    p967 Petr Stepanov, Shi Che, Dmitry Shcherbakov, Jiawei Yang, Ruoyu Chen et al. doi:10.1038/s41567-018-0237-2 Author Correction: Pair-breaking quantum phase transition in superconducting nanowires    p967 Hyunjeong Kim, Frédéric Gay, Adrian Del Maestro, Benjamin Sacépé & Andrey Rogachev doi:10.1038/s41567-018-0251-4 Publisher Correction: Maximal spontaneous photon emission and energy loss from free electrons    p967 Yi Yang, Aviram Massuda, Charles Roques-Carmes, Steven E.
