Susanne N. Gröbner, Barbara C. Worst, Joachim Weischenfeldt et al. | The atomic structure of a eukaryotic oligosaccharyltransferase complex The high-resolution structure of the entire eukaryotic oligosaccharyltransferase complex is determined, revealing the role of membrane lipids in mediating inter-subunit interactions, and the mechanism by which the complex enables protein N-glycosylation. Lin Bai, Tong Wang, Gongpu Zhao et al. | | Two chemically similar stellar overdensities on opposite sides of the plane of the Galactic disk Fourteen stars from stellar overdensities above and below the Galactic disk have the same elemental abundances as disk stars, suggesting that these stars originated in the disk, perhaps being removed during interaction with passing dwarf galaxies. Maria Bergemann, Branimir Sesar, Judith G. Cohen et al. | Confocal non-line-of-sight imaging based on the light-cone transform A confocal scanning technique solves the reconstruction problem of non-line-of-sight imaging to give fast and high-quality reconstructions of hidden objects. Matthew O’Toole, David B. Lindell, Gordon Wetzstein | Observation of a phononic quadrupole topological insulator A two-dimensional phononic quadrupole topological insulator is demonstrated experimentally using mechanical metamaterials, which has both the one-dimensional edge states and the zero-dimensional corner states predicted by theory. Marc Serra-Garcia, Valerio Peri, Roman Süsstrunk et al. | A quantized microwave quadrupole insulator with topologically protected corner states A quantized quadrupole topological insulator composed of capacitively coupled microwave resonators has corner states that are protected by bulk topology and exhibit exceptional robustness against edge deformation. Christopher W. Peterson, Wladimir A. Benalcazar, Taylor L. Hughes et al. | High-resolution magnetic resonance spectroscopy using a solid-state spin sensor High-resolution nuclear magnetic resonance spectroscopy at the scale of single cells is achieved by combining a magnetometer consisting of an ensemble of nitrogen–vacancy centres with a narrowband synchronized readout protocol. David R. Glenn, Dominik B. Bucher, Junghyun Lee et al. | Redox-influenced seismic properties of upper-mantle olivine Redox conditions and associated defect chemistry rather than water content, as previously thought, strongly influence the seismic properties of olivine, the main constituent mineral of Earth’s upper mantle. C. J. Cline II, U. H. Faul, E. C. David et al. | Altruism in a volatile world A derivation of Hamilton’s rule that considers explicit environmental stochasticity can predict when organisms should pay a cost to influence the variance in the reproductive success of their relatives, formalizing the link between bet-hedging and altruism. Patrick Kennedy, Andrew D. Higginson, Andrew N. Radford et al. | Pursuing sustainable productivity with millions of smallholder farmers Millions of Chinese smallholder farmers were persuaded to adopt enhanced management practices, which led to a greater yield, reduced nitrogen fertilizer use and improved environmental performance throughout China. Zhenling Cui, Hongyan Zhang, Xinping Chen et al. | Pervasive phosphorus limitation of tree species but not communities in tropical forests In lowland tropical forests in Panama, widespread species-level phosphorus limitation of tree growth is not reflected in community-wide growth or biomass owing to the presence of a few species tolerant of low phosphorus availability. Benjamin L. Turner, Tania Brenes-Arguedas, Richard Condit | Pan-cancer genome and transcriptome analyses of 1,699 paediatric leukaemias and solid tumours OPEN Analysis of the genomes, exomes and transcriptomes of 1,699 childhood cancers identifies 142 driver genes. Xiaotu Ma, Yu Liu, Yanling Liu et al. | Human hippocampal neurogenesis drops sharply in children to undetectable levels in adults Recruitment of young neurons to the hippocampus decreases rapidly during the first years of life, and neurogenesis does not continue, or is extremely rare, in the adult human brain. Shawn F. Sorrells, Mercedes F. Paredes, Arantxa Cebrian-Silla et al. | Recognition of DHN-melanin by a C-type lectin receptor is required for immunity to Aspergillus The C-type lectin receptor MelLec recognizes DHN-melanin in conidial spores of Aspergillus fumigatus and other DHN-melanized fungi, revealing an important role for this receptor in antifungal immunity in both mice and humans. Mark H. T. Stappers, Alexandra E. Clark, Vishukumar Aimanianda et al. | EWS–FLI1 increases transcription to cause R-loops and block BRCA1 repair in Ewing sarcoma The EWS–FLI1 fusion protein, expressed in Ewing sarcoma, increases global transcription, causes accumulation of R loops and replication stress, and impairs BRCA1-mediated repair. Aparna Gorthi, July Carolina Romero, Eva Loranc et al. | Epigenetic reprogramming enables the transition from primordial germ cell to gonocyte Gonadal germline epigenetic reprogramming involves an interplay between DNA methylation, the polycomb complex and Tet1 in both DNA methylation dependent and independent roles, to ensure the activation of a specific subset of genes critical for progression of gametogenesis. Peter W. S. Hill, Harry G. Leitch, Cristina E.
