M. Barlow, Erin L. McClymont, Pippa L. Whitehouse, Chris R. Stokes, Stewart S. R. Jamieson et al. doi:10.1038/s41561-018-0195-4 Robust evidence for a previously proposed sea-level fall and rise during the Last Interglacial is lacking, according to a synthesis. This calls estimates of high rates of sea-level rise at the end of the Last Interglacial into question. Articles Magnetite authigenesis and the warming of early Mars    pp635 - 639 Nicholas J. Tosca, Imad A. M. Ahmed, Benjamin M. Tutolo, Alice Ashpitel et al. doi:10.1038/s41561-018-0203-8 Experiments suggest that magnetite precipitation on early Mars was accompanied by the release of H2 that may have helped to warm the planet and stabilize liquid water at the Martian surface. Enhanced global primary production by biogenic aerosol via diffuse radiation fertilization    pp640 - 644 A. Rap, C. E. Scott, C. L. Reddington, L. Mercado, R. J. Ellis et al. doi:10.1038/s41561-018-0208-3 Biogenic aerosols produced by terrestrial vegetation substantially enhance global primary productivity of plants, according to integrated model analyses. A long-term decrease in the persistence of soil carbon caused by ancient Maya land use    pp645 - 649 Peter M. J. Douglas, Mark Pagani, Timothy I. Eglinton, Mark Brenner, Jason H. Curtis et al. doi:10.1038/s41561-018-0192-7 Deforestation by the ancient Maya led to a destabilization of organic carbon preserved in the underlying soils and reduced the magnitude of the soil carbon sink in this region. Holocene dynamics of the Southern Hemisphere westerly winds and possible links to CO2 outgassing    pp650 - 655 Krystyna M. Saunders, Stephen J. Roberts, Bianca Perren, Christoph Butz, Louise Sime et al. doi:10.1038/s41561-018-0186-5 The strength of the Southern Hemisphere westerly winds varied throughout the Holocene, according to a reconstruction from lake sediments, with periods of stronger winds coincident with higher atmospheric CO2 levels. Transient temperature asymmetry between hemispheres in the Palaeogene Atlantic Ocean    pp656 - 660 Zhonghui Liu, Yuxin He, Yiqing Jiang, Huanye Wang, Weiguo Liu et al. doi:10.1038/s41561-018-0182-9 Northern and Southern hemisphere temperatures were decoupled during the Eocene/Oligocene transition, suggests a sea surface temperature record from the North Atlantic. Riverine evidence for isotopic mass balance in the Earth's early sulfur cycle    pp661 - 664 Mark A. Torres, Guillaume Paris, Jess F. Adkins & Woodward W. Fischer doi:10.1038/s41561-018-0184-7 The isotopic composition of sulfur minerals formed during the Archaean can be reconstructed from dissolved sulfur in rivers draining cratons. Analyses from Canada suggest that the Archaean sulfur cycle was in isotopic mass balance. Microbial life and biogeochemical cycling on land 3,220 million years ago    pp665 - 671 Martin Homann, Pierre Sansjofre, Mark Van Zuilen, Christoph Heubeck, Jian Gong et al. doi:10.1038/s41561-018-0190-9 Microbial life colonized the land surface by 3.2 billion years ago, forming complex communities distinct from those in nearby marine environments, according to analyses of fossilized microbial mats in the Moodies Group, South Africa. Self-organization of a biogeomorphic landscape controlled by plant life-history traits    pp672 - 677 Christian Schwarz, Olivier Gourgue, Jim van Belzen, Zhenchang Zhu, Tjeerd J. Bouma et al. doi:10.1038/s41561-018-0180-y Fast-colonizing plants stabilize wetland landscapes, whereas slow-colonizing plants promote channel formation according to biogeomorphic model simulations and field observations. Influence of eruptive style on volcanic gas emission chemistry and temperature    pp678 - 681 Clive Oppenheimer, Bruno Scaillet, Andrew Woods, A. Jeff Sutton, Tamar Elias et al. doi:10.1038/s41561-018-0194-5 The redox state of volcanic gases and melts can become decoupled during magma ascent, according to observations of gas emissions from Kilauea's lava lake, Hawaii. Cooling of fast-rising bubbles changes the abundance of redox-sensitive gas species. End-Permian extinction amplified by plume-induced release of recycled lithospheric volatiles    pp682 - 687 Michael W. Broadley, Peter H. Barry, Chris J. Ballentine, Lawrence A. Taylor & Ray Burgess doi:10.1038/s41561-018-0215-4 Halogens in Siberian xenoliths show that plume–lithosphere interaction controls the volatile content of large igneous provinces. The seawater-derived volatiles, implicated in the end-Permian mass extinction, infiltrated the lithosphere during subduction. Forced subduction initiation recorded in the sole and crust of the Semail Ophiolite of Oman    pp688 - 695 Carl Guilmette, Matthijs A. Smit, Douwe J. J. van Hinsbergen, Derya Gürer, Fernando Corfu et al. doi:10.1038/s41561-018-0209-2 The subduction system recorded by the Semail Ophiolite of Oman was initiated by far-field events, according to a comparison of the ages of the upper and lower plate material. Deep earthquakes in subducting slabs hosted in highly anisotropic rock fabric    pp696 - 700 Jiaxuan Li, Yingcai Zheng, Leon Thomsen, Thomas J. Lapen & Xinding Fang doi:10.1038/s41561-018-0188-3 Radiation patterns for deep earthquakes could be a result of shear faulting mechanisms—similar to those for shallow earthquakes—but in highly anisotropic rock fabric, suggest seismic analyses.
