About the cover

Can you keep secrets safe from eavesdroppers? Yes you can, say Artur Ekert and Renato Renner. They argue that recent developments in quantum cryptography, coupled with the fact that we still possess free will, suggest that truly private communication will always be possible, even in a world with access to as yet undiscovered code-breaking technologies. The answer lies in new insights into the nature of randomness and non-local correlations. Thus equipped it should be possible to outsmart even the most powerful surveillance procedures.

  • The ultimate physical limits of privacy

    • Artur Ekert

    Developments in quantum cryptography show that it is possible to protect secrets — from those with superior technology, those who profess to provide our security and even those who manipulate us without our knowledge — under surprisingly weak assumptions.

    REST, a developmental regulator, is markedly induced in human neurons during ageing but is lost in Alzheimer’s disease; REST represses genes that promote neurodegeneration, is neuroprotective in animal models, and is associated with cognitive preservation and longevity in humans.

    The discrepancy between the components of the oceanic carbon budget — export of carbon from the surface and its conversion into carbon dioxide by water-column biota at depth — is reconciled using field data and a steady-state model which indicates that synergy between microbes and zooplankton is an important factor.

  • Methane fluxes show consistent temperature dependence across microbial to ecosystem scales

    • Annick St-Pierre
    • Nguyen Thanh-Duc
    • Paul A. del Giorgio

    Meta-analyses show that the temperature dependence of methane fluxes scales consistently across populations of methanogens, microbial communities and whole ecosystems, and that this temperature dependence is higher than for respiration and photosynthesis; this indicates that global warming may impact the relative contributions of CO2 and CH4 to total greenhouse gas emissions.

    Global maps constructed using climate-change velocities to derive spatial trajectories for climatic niches between 1960 and 2100 show past and future shifts in ecological climate niches; properties of these trajectories are used to infer changes in species distributions, and thus identify areas that will act as climate sources and sinks, and geographical barriers to species migrations.

    Tamisiocaris borealis, an Early Cambrian member of the anomalocarids—giant, predatory marine stem arthropods—probably used its frontal appendage to trap microscopic, planktonic animals.

  • Visual space is compressed in prefrontal cortex before eye movements

    • Tirin Moore

    Saccadic eye movements cause substantial shifts in the retinal image as we take in visual scenes, but our perception is stable and continuous; here, visual receptive fields are shown to shift dramatically towards the saccadic goal, running counter to the long-standing hypothesis of receptive field remapping as the basis of perceived stability.
