Vol 515, No. 7526, November 2014, The Great Depression


    Mental health: Depression needs large human-genetics studies

    To understand the molecular mechanisms of depression, collect genetic data from more than 100,000 people, says Steven Hyman.
    Infectious disease: Tough choices to reduce Ebola transmission

    Christopher J. M. Whitty and colleagues explain why the United Kingdom is funding many small community centres to isolate suspected cases in Sierra Leone.
    Film: Enigma variations

    Robert P. Crease ponders a brace of biopics on Alan Turing and Stephen Hawking.
        Review of The Imitation Game and The Theory of Everything

    Q&A: Space-time visionary

    Thanks to theoretical physicist Kip Thorne, real science is embedded in Christopher Nolan's film Interstellar, in which explorers seek a new home for humankind. Thorne talks about what he learned from the film's unprecedented visualizations of black holes and wormholes, what it and his accompanying book can teach, and the likelihood of humans escaping the Solar System.

    Synaptic, transcriptional and chromatin genes disrupted in autism
        Silvia De Rubeis,
        Xin He,
        Arthur P. Goldberg,
        Christopher S. Poultney,
        Kaitlin Samocha
        + et al.

    Whole-exome sequencing in a large autism study identifies over 100 autosomal genes that are likely to affect risk for the disorder; these genes, which show unusual evolutionary constraint against mutations, carry de novo loss-of-function mutations in over 5% of autistic subjects and many function in synaptic, transcriptional and chromatin-remodelling pathways.
    The contribution of de novo coding mutations to autism spectrum disorder
        Ivan Iossifov,
        Brian J. O’Roak,
        Stephan J. Sanders,
        Michael Ronemus,
        Niklas Krumm
        + et al.

    Family-based exome sequencing in a large autism study has identified 27 high-confidence gene targets and accurately estimates the contribution of both de novo gene-disrupting and missense mutations to the incidence of simplex autism, with target genes in affected females overlapping those in males of lower but not higher IQ; targets also overlap known targets for intellectual disability and schizophrenia, and are enriched for chromatin modifiers, FMRP-associated genes and embryonically expressed genes.
    Evolution of mosquito preference for humans linked to an odorant receptor
        Carolyn S. McBride,
        Felix Baier,
        Aman B. Omondi,
        Sarabeth A. Spitzer,
        Joel Lutomiah
        + et al.

    The mosquito Aedes aegypti includes two subspecies, one of which shows a preference for biting humans, whereas the other prefers to bite non-human animals; genetic analysis reveals that changes in the mosquito odorant receptor Or4 contribute to the behavioural difference—in human-preferring mosquitoes, Or4 is more highly expressed and more sensitive to sulcatone, a compound present at high levels in human odour.
    Clathrin regenerates synaptic vesicles from endosomes
        Shigeki Watanabe,
        Thorsten Trimbuch,
        Marcial Camacho-Pérez,
        Benjamin R. Rost,
        Bettina Brokowski
        + et al.

    Ultrastructural analysis of synaptic vesicle recycling reveals that clathrin is not required for the initial rapid step of vesicle recycling by ultrafast endocytosis at the plasma membrane and instead clathrin acts later at an endosome to regenerate synaptic vesicles; however, when ultrafast endocytosis does not occur (for example, in experiments at room temperature rather than physiological temperature), clathrin-mediated endocytosis does happen at the plasma membrane.

    The expanding fireball of Nova Delphini 2013
        G. H. Schaefer,
        T. ten Brummelaar,
        D. R. Gies,
        C. D. Farrington,
        B. Kloppenborg
        + et al.

    High spatial resolution is needed to study the early development of a nova; here measurements of the angular size and radial velocity of Nova Delphini 2013 reveal early structures in the ejected material and a geometric distance to the nova of about 4.5 kiloparsecs from the Sun.
    Experimental realization of the topological Haldane model with ultracold fermions
        Gregor Jotzu,
        Michael Messer,
        Rémi Desbuquois,
        Martin Lebrat,
        Thomas Uehlinger
        + et al.

    The Haldane model, which predicts complex topological states of matter, has been implemented by placing ultracold atoms in a tunable optical lattice that was deformed and shaken.

        C. Neill,
        Yu Chen,
        M. Kolodrubetz,
        C. Quintana
        + et al.

    Superconducting quantum circuits are used to directly observe and characterize topological phase transitions; this approach promises to be a powerful and general platform for characterizing topological phenomena in quantum systems.

    Formic-acid-induced depolymerization of oxidized lignin to aromatics
        Alireza Rahimi,
        Arne Ulbrich,
        Joshua J. Coon &
        Shannon S. Stahl

    A method for the depolymerization of oxidized lignin under mild conditions in aqueous formic acid is described that results in more than 60 wt% yield of low-molecular-mass aromatics.
    Subduction-driven recycling of continental margin lithosphere
        A. Levander,
        M. J. Bezada,
        F. Niu,
        E. D. Humphreys,
        I. Palomeras
        + et al.

    Seismic images of the subducted Atlantic slab under northeastern South America and the Alboran slab beneath the Gibraltar arc region show that subducting oceanic plates viscously entrain and remove the bottom of the continental thermal boundary layer from adjacent continental margins, driving surface tectonics and pre-conditioning the margins for further deformation.
    Resolving the long-standing enigmas of a giant ornithomimosaur Deinocheirus mirificus
        Yuong-Nam Lee,
        Rinchen Barsbold,
        Philip J. Currie,

    A three-dimensional human neural cell culture model of Alzheimer’s disease
        Se Hoon Choi,
        Young Hye Kim,
        Matthias Hebisch,
        Christopher Sliwinski,
        Seungkyu Lee

        Jing Li,
        Bing Hou,
        Sarka Tumova,
        Katsuhiko Muraki,
        Alexander Bruns
        + et al.

    The Piezo1 calcium-permeable channel is revealed to have a role in the vascular cellular response to shear stress; a mouse knockout reveals that this channel is also important for normal vascular development.
    The complete structure of the large subunit of the mammalian mitochondrial ribosome
        Basil J. Greber,
        Daniel Boehringer,
        Marc Leibundgut,
        Philipp Bieri,
        Alexander Leitner
        + et al.

    The structure of the 39S large mitoribosome subunit is solved by cryo-electron microscopy at an impressive 3.4 Å resolution, revealing the location of 50 ribosomal proteins, the peptidyl transferase centre, the tRNAs within this active site, and the nascent peptide chain within the exit tunnel.
    Structural basis for the assembly of the Sxl–Unr translation regulatory complex
        Janosch Hennig,
        Cristina Militti,
        Grzegorz M. Popowicz,
        Iren Wang,
        Miriam Sonntag
        + et al.

    The crystal structure of the RNA binding domains of Sxl and Unr with msl2 RNA shows that interwoven interactions establish cooperative assembly of the ternary complex, highlighting how binding of relatively general RNA binding domains to RNA can result in a unique and specific protein–RNA architecture.
