By analogy with its charge counterpart, this effect is termed spin colossal magnetoresistance. [ ] [Observation of magnetic vortex pairs at room temperature in a planar α-Fe2O3/Co heterostructure pp581 - 585]( F. P. Chmiel, N. Waterfield Price, R. D. Johnson, A. D. Lamirand, J. Schad et al. doi:10.1038/s41563-018-0101-x Magnetic vortices formed in antiferromagnetic haematite and imprinted on a Co ferromagnetic over-layer have been observed using X-ray magnetic linear and circular dichroism photoemission electron microscopy. These vortex pairs can be manipulated by the application of magnetic fields. [ ] [Terahertz-light quantum tuning of a metastable emergent phase hidden by superconductivity pp586 - 591]( X. Yang, C. Vaswani, C. Sundahl, M. Mootz, P. Gagel et al. doi:10.1038/s41563-018-0096-3 THz pump–probe experiments of superconducting Nb3Sn reveal that a metastable phase is induced for excitation fields around 250?kV?cm-1. [ ] [Electrifying model catalysts for understanding electrocatalytic reactions in liquid electrolytes pp592 - 598]( Firas Faisal, Corinna Stumm, Manon Bertram, Fabian Waidhas, Yaroslava Lykhach et al. doi:10.1038/s41563-018-0088-3 Fundamental understanding of electrocatalysis is key to a transition to renewable energy systems. A strategy to 'electrify' complex oxide-based model catalysts is now proposed to explore electrocatalytic reactions in liquid electrolytes. [ ] [Homochiral porous nanosheets for enantiomer sieving pp599 - 604]( Bo Sun, Yongju Kim, Yanqiu Wang, Huaxin Wang, Jehan Kim et al. doi:10.1038/s41563-018-0107-4 By using stacked macrocycle dimers, a 2D nanosheet self-assembles that exclusively captures a single enantiomer, and can release it by external stimulus via salt addition. [] Articles [ ] [Significant Dzyaloshinskii–Moriya interaction at graphene–ferromagnet interfaces due to the Rashba effect pp605 - 609]( Hongxin Yang, Gong Chen, Alexandre A. C. Cotta, Alpha T. N'Diaye, Sergey A. Nikolaev et al. doi:10.1038/s41563-018-0079-4 Authors investigate graphene/cobalt and graphene/nickel interfaces, and observe a non-zero Dzyaloshinskii–Moriya interaction that they attribute to the Rashba effect; calculations suggest the effect can be enhanced in van der Waals heterostructures. [ ] [Interplay of water and reactive elements in oxidation of alumina-forming alloys pp610 - 617]( N. Mortazavi, C. Geers, M. Esmaily, V. Babic, M.

[ ] [An autonomously electrically self-healing liquid metal–elastomer composite for robust soft-matter robotics and electronics pp618 - 624]( Eric J. Markvicka, Michael D. Bartlett, Xiaonan Huang & Carmel Majidi doi:10.1038/s41563-018-0084-7 Liquid metal droplets dispersed in an elastomer can form conducting paths when the composite is exposed to extreme mechanical pressure. This ability is used to realize flexible circuits that autonomously electrically self-heal after puncturing or tearing. [ ] [Electron delocalization and charge mobility as a function of reduction in a metal–organic framework pp625 - 632]( Michael L. Aubrey, Brian M. Wiers, Sean C. Andrews, Tsuneaki Sakurai, Sebastian E. Reyes-Lillo et al. doi:10.1038/s41563-018-0098-1 A conducting metal–organic framework with charge delocalization by reductive potassium insertion is demonstrated. Integration into a field-effect transistor shows similar mobilities to semiconductors, with a mobility estimated to be at least 0.84 cm2 V–1 s–1. [ ] [Mechanics-guided embryonic patterning of neuroectoderm tissue from human pluripotent stem cells pp633 - 641]( Xufeng Xue, Yubing Sun, Agnes M. Resto-Irizarry, Ye Yuan, Koh Meng Aw Yong et al. doi:10.1038/s41563-018-0082-9 Mechanical cues play critical roles in embryonic development. A micropatterned neuroectoderm developmental model based on human pluripotent stem cells now reveals how morophogenetic signals such as cell shape and contractility regulate neural tissue development. [ ] [Dual-function injectable angiogenic biomaterial for the repair of brain tissue following stroke pp642 - 651]( Lina R. Nih, Shiva Gojgini, S. Thomas Carmichael & Tatiana Segura doi:10.1038/s41563-018-0083-8 Stimulation of angiogenesis after stroke is not always an effective therapy. An injectable hydrogel with pro-angiogenic and immune-modulating factors is now shown to support blood vessel, axonal and functional recovery following stroke.
