About the cover

Some individuals can cope with stress — from the extremes of battle to the pressures of modern life — with no apparent ill effects. Others in similar situations will develop serious mental illness. The efforts of neuroscientists to track down the elusive links between life experience and mental illness are the focus of a series of articles in this week’s Nature. Cover: Paddy Mills

  • The hexadehydro-Diels–Alder reaction

    • Thomas R. Hoye
    • Beeraiah Baire
    • Dawen Niu
    • Patrick H. Willoughby
    • Brian P. Woods

    The de novo generation of benzynes—through a hexadehydro-Diels–Alder reaction—followed by their in situ elaboration is reported; the reaction is metal-free and reagent-free, and reveals new modes of intrinsic benzyne reactivity.

  • Small heat-shock proteins protect from heat-stroke-associated neurodegeneration

    • Nikos Kourtis
    • Vassiliki Nikoletopoulou
    • Nektarios Tavernarakis

    Heat stroke triggers necrotic cell death and neurodegeneration in Caenorhabditis elegans, but hormetic preconditioning at a mildly elevated temperature strongly protects C. elegans from necrosis induced by several insults, including heat, and shields mammalian neurons from heat cytotoxicity, suggesting that this protective mechanism is conserved.

  • Retinal waves coordinate patterned activity throughout the developing visual system

    • James B. Ackman
    • Timothy J. Burbridge
    • Michael C. Crair

    In live neonatal mice, waves of spontaneous retinal activity are present and can propagate patterned information capable of guiding activity-dependent development of complex intra- and inter-hemispheric circuits throughout the visual system before the onset of vision (before eye opening).

  • A neural circuit for spatial summation in visual cortex

    • Hillel Adesnik
    • William Bruns

    • Z. Josh Huang
    • Massimo Scanziani

    The activity of somatostatin-expressing inhibitory neurons (SOMs) in the superficial layers of the mouse visual cortex increases with stimulation of the receptive-field surround, thereby contributing to the surround suppression of pyramidal cells.

    The two earthquakes of respective magnitudes 8.6 and 8.2 that occurred off the coast of the Sumatra subduction zone on 11 April 2012 are shown to be part of a continuing boost of the intraplate deformation between India and Australia that followed the Aceh 2004 and Nias 2005 megathrust earthquakes.

    Global yields of major crops are analysed using climate, irrigation and new nutrient data to show that large production increases are possible from closing yield gaps to 100% of attainable yields, and that changes in management practices needed to close yield gaps vary considerably by region and current intensity.

  • Complex brain and optic lobes in an early Cambrian arthropod

    • Xiaoya Ma

    • Gregory D. Edgecombe
    • Nicholas J. Strausfeld

    An arthropod specimen from an early Cambrian deposit in China shows a nervous system very similar to that of modern insects and crustaceans, suggesting that insect and crustacean nervous systems evolved from a relatively complex ancestral one, and that simple animals, such as branchiopod shrimps, have evolved a marked reduction in the complexity of their nervous systems.

    Two types of human ES-cell-derived otic progenitors are shown to have the ability to differentiate in vitro into hair-cell-like cells and auditory neurons, and to engraft, differentiate and improve auditory-evoked response thresholds when transplanted into an auditory neuropathy model; this indicates that it may be possible to use cell-based therapeutic strategies to recover damaged sensory circuitry in deafness.

    Using intravital microscopy, this study visualizes HIV-1-infected T cells within the lymph nodes of humanized mice, demonstrating that infected cells have reduced motility and long membrane processes; treating infected mice with a lymphocyte egress inhibitor prevents HIV-1 from spreading to the circulation during the course of treatment.
