How fish feel the flow p.406

Hair-like sensors are suspected to aid fish navigation in complex environments. Laboratory experiments and computational simulations reveal how these sensors can detect water flow to direct the swimming responses of fish. See Letter p.445

A new spin on nanoscale computing p.407

A nanoscale magnetic device that mimics the behaviour of neurons has been used to recognize audio signals. Such a device could be adapted to tackle tasks with greater efficiency than conventional computers. See Letter p.428

Synapses get together for vision p.408

A sophisticated analysis in mice of how inputs to neurons from other neurons are distributed across individual cells of the brain's visual cortex provides information about how mammalian vision is processed. See Letter p.449

Molecular structure assignment simplified p.410

An innovative combination of chemical synthesis, theory and spectroscopy could simplify determination of the structures of naturally occurring, biologically active molecules, which are often leads for drug discovery. See Letter p.436a

Towards polio eradication p.411

Polio has almost been eradicated. A field study demonstrates that a combination of focused science and epidemiology, and community-based integrated health approaches, are required to finish the job.

Maternal H3K27me3 controls DNA methylation-independent imprinting p.419

Analysis of parental allele-specific chromatin accessibility genome-wide in mouse zygotes and morula embryos, and investigation of the epigenetic mechanisms underlying these allelic sites, identifying maternal H3K27me3 as a DNA methylation-independent mechanism for genomic imprinting.

Synaptic organization of visual space in primary visual cortex p.449

Mapping the organization of excitatory inputs onto the dendritic spines of individual mouse visual cortex neurons reveals how inputs representing features from the extended visual scene are organized and establishes a computational unit suited to amplify contours and elongated edges.
