Jessica Gurevitch, Julia Koricheva, Shinichi Nakagawa et al. | | GaN/NbN epitaxial semiconductor/superconductor heterostructures Group III/nitride semiconductors have been grown epitaxially on the superconductor niobium nitride, allowing the superconductor’s macroscopic quantum effects to be combined with the semiconductors’ electronic, photonic and piezoelectric properties. Rusen Yan, Guru Khalsa, Suresh Vishwanath et al. | The Beaker phenomenon and the genomic transformation of northwest Europe Genome-wide data from 400 individuals indicate that the initial spread of the Beaker archaeological complex between Iberia and central Europe was propelled by cultural diffusion, but that its spread into Britain involved a large-scale migration that permanently replaced about ninety per cent of the ancestry in the previously resident population. Iñigo Olalde, Selina Brace, Morten E. Allentoft et al. | The genomic history of southeastern Europe Genome-wide ancient DNA data from 225 individuals who lived in southeastern Europe between 12000 and 500 ʙᴄ reveals that the region acted as a genetic crossroads before and after the arrival of farming. Iain Mathieson, Songül Alpaslan-Roodenberg, Cosimo Posth et al. | Hierarchical neural architecture underlying thirst regulation Thirst is regulated by hierarchical neural circuits in the lamina terminalis, and these integrate the instinctive need for water with consequent drinking behaviour to maintain internal water homeostasis. Vineet Augustine, Sertan Kutal Gokce, Sangjun Lee et al. | Environment dominates over host genetics in shaping human gut microbiota Statistical analyses of a metagenomics-sequenced human cohort identify a relatively minor role for genetics in determining microbiome composition and show that several human phenotypes are as strongly associated with the gut microbiome as with host genetics. Daphna Rothschild, Omer Weissbrod, Elad Barkan et al. | | Clusters of cyclones encircling Jupiter’s poles Visible and infrared images obtained from above each pole of Jupiter by the Juno spacecraft reveal polygonal patterns of large cyclones; it is unknown how these cyclones evolved, or how they persist without merging. A. Adriani, A. Mura, G. Orton et al. | Measurement of Jupiter’s asymmetric gravity field Precise Doppler tracking of the Juno spacecraft in its polar orbit around Jupiter is used to determine the planet’s gravity harmonics, showing north–south asymmetry caused by atmospheric and interior flows. L. Iess, W. M. Folkner, D. Durante et al. | Jupiter’s atmospheric jet streams extend thousands of kilometres deep The determination of Jupiter’s odd gravitational harmonics by the Juno spacecraft reveals that the observed jet streams extend to about three thousand kilometres below the cloud tops. Y. Kaspi, E. Galanti, W. B. Hubbard et al. | A suppression of differential rotation in Jupiter’s deep interior The determination of Jupiter’s even gravitational moments by the Juno spacecraft reveals that more than three thousand kilometres below the cloud tops, differential rotation is suppressed and the gas giant’s interior rotates as a solid body. T. Guillot, Y. Miguel, B. Militzer et al. | Monolayer atomic crystal molecular superlattices Superlattices consisting of alternating monolayer atomic crystals and molecular layers allow access to stable phosphorene monolayers with competitive transistor performance and to bulk monolayer materials with tunable optoelectronic properties. Chen Wang, Qiyuan He, Udayabagya Halim et al. | CaSiO3 perovskite in diamond indicates the recycling of oceanic crust into the lower mantle The composition of natural calcium silicate perovskite, the fourth most abundant mineral in the Earth, found within a diamond indicates an origin from oceanic crust subducted deeper than 700 kilometres into the Earth’s mantle. F. Nestola, N. Korolev, M. Kopylova et al. | Social norm complexity and past reputations in the evolution of cooperation In a binary decision game in which players strategically help certain individuals but not others, simple moral principles maximize cooperation, even when including the historical reputations of players. Fernando P. Santos, Francisco C. Santos, Jorge M. Pacheco | Global elevational diversity and diversification of birds A global study of all bird species in mountainous areas shows that richness decreases predictably with elevation, whereas diversification rates increase. Ignacio Quintero, Walter Jetz | Regeneration of the lung alveolus by an evolutionarily conserved epithelial progenitor An evolutionarily conserved alveolar epithelial progenitor lineage that derives from alveolar type 2 cells is responsive to Wnt signalling and acts as a major facultative progenitor in regenerating the distal lung. William J. Zacharias, David B. Frank, Jarod A. Zepp et al. | The SMAD2/3 interactome reveals that TGFβ controls m6A mRNA methylation in pluripotency The SMAD2 and SMAD3 protein interactome links TGFβ signalling to diverse effectors including m6A methyltransferase, which has a role in regulating differentiation of human pluripotent stem cells. Alessandro Bertero, Stephanie Brown, Pedro Madrigal et al. | Hierarchical roles of mitochondrial Papi and Zucchini in Bombyx germline piRNA biogenesis The biogenesis of piRNAs in the silkworm Bombyx is simpler than in Drosophila, with the exonucleases Trim and Nbr having no major role, and the endonuclease Zuc acting at the 3′ rather than the 5′ end. Kazumichi M. Nishida, Kazuhiro Sakakibara, Yuka W. Iwasaki et al. | The mechanism of eukaryotic CMG helicase activation In vitro experiments, using purified proteins and an assay that detects DNA unwinding, reveal the mechanism of activation of eukaryotic DNA replication. Max E. Douglas, Ferdos Abid Ali, Alessandro Costa et al. | Structure of the D2 dopamine receptor bound to the atypical antipsychotic drug risperidone An X-ray structure of the D2 dopamine receptor bound to the atypical antipsychotic drug risperidone reveals an extended binding pocket and indicates structural features that could be used to design drugs that specifically target the D2 receptor.
