  Valley-selective circular dichroism of monolayer molybdenum disulphide

  The monolayer transition-metal dichalcogenide molybdenum disulphide has recently attracted attention owing to its distinctive electronic properties. Cao and co-workers present numerical evidence suggesting that circularly polarized light can preferentially excite a single valley in the band structure of this system.

  The impacts of climate change on water resources and agriculture in China

  China has tremendous climatic and ecological diversity, so the impacts of climate change on natural and managed systems might likewise be expected to be diverse. Yet so far systematic studies have been rare. Here, the impacts of historical and future climate change on water resources and agriculture in China are assessed. Despite clear trends in climate, the overall impacts are overshadowed by natural variability and uncertainties in crop responses and projected climate, especially precipitation.

  Calcium flickers steer cell migration

  Directional cell movement depends on an intracellular calcium gradient. This study identifies calcium flickers in migrating fibroblasts and these are most active at the leading edge of cells. In the presence of a chemotactic gradient, an asymmetric gradient of calcium flicker activity develops which promotes turning of cells towards the direction of the chemoattractant.

  Chirality-specific growth of single-walled carbon nanotubes on solid alloy catalysts

  Single-walled carbon nanotubes of a single chirality can be produced with an abundance of more than 92 per cent when using tungsten-based bimetallic alloy nanocrystals as catalysts.

  An ultraluminous quasar with a twelve-billion-solar-mass black hole at redshift 6.30

  Observations of an ultraluminous quasar, SDSS J010013.02+280225.8, at redshift z = 6.30 show that the object has an optical and near-infrared luminosity a few times greater than those of previously known quasars at z > 6; the black hole that drives the quasar has a mass about 12 billion times that of the Sun.

  Topological insulator nanostructures for near-infrared transparent flexible electrodes

  Transparent conductive electrodes are widely used in modern optoelectronic devices, but they are rarely transparent in the near-infrared, limiting their use. Nanostructured bismuth selenide, a topological insulator, is now shown to be a flexible near-infrared transparent electrode.

  Genome-wide association study identifies a susceptibility locus for schizophrenia in Han Chinese at 11p11.2

  Dai Zhang and colleagues report a genome-wide association study for schizophrenia in the Han Chinese population. They identify a new susceptibility locus at 11p11.2 and also identify a locus at 6p21-22.1 in the extended MHC region, which has previously been reported to be associated with schizophrenia in individuals of European descent.

  PCBP2 mediates degradation of the adaptor MAVS via the HECT ubiquitin ligase AIP4

  The mitochondrial adaptor MAVS is necessary for the transmission of RIG-I and Mda5 antiviral signals. Jiang and colleagues show that PCBP2 negatively regulates MAVS stability by recruiting the L48-ubiquitinating enzyme AIP4, thereby preventing excessive cytokine responses.
