    Herbivory-induced volatiles function as defenses increasing fitness of the native plant Nicotiana attenuata in nature

    Meredith C Schuman et al.
    A 2-year field study has demonstrated that volatile compounds produced by plants when they are attacked by herbivores act as defenses by attracting predators to the herbivores and increasing the reproduction of the plants.

    The unfolded protein response in fission yeast modulates stability of select mRNAs to maintain protein homeostasis

    Philipp Kimmig et al.
    A unique form of regulation has been observed in the unfolded protein response of S. pombe, along with a novel mechanism of post-transcriptional mRNA processing.

    Molecular architecture of human polycomb repressive complex 2

    Claudio Ciferri et al.
    Electron microscopy has been used to produce the first three-dimensional image of the PRC2 gene-silencing complex.

    Foggy perception slows us down

    Paolo Pretto et al.
    Virtual reality experiments show that motorists slow down when driving in fog, but they speed up when visibility is reduced equally at all distances.

    Nascent-Seq reveals novel features of mouse circadian transcriptional regulation

    Jerome S Menet et al.
    Genome-wide measurements on mouse liver cells show that transcription, and a particular key transcription factor, have a smaller than expected influence on the mouse circadian system.

    Global divergence in critical income for adult and childhood survival: analyses of mortality using Michaelis–Menten

    Ryan J Hum et al.
    A mathematical model based on enzyme kinetics shows how the relationships between life expectancy, survival rates for children and adults, and national income change over time.

    Synaptic proteins promote calcium-triggered fast transition from point contact to full fusion

    Jiajie Diao et al.
    A combination of advanced optical imaging and cryogenic electron microscopy has been used to explore membrane fusion in a synthetic system and provide new insights into neurotransmitter release.

    The activity-dependent histone variant H2BE modulates the life span of olfactory neurons

    Stephen W Santoro, Catherine Dulac
    A genome-organizing protein that is present only in the olfactory system of mice has been found to orchestrate changes in the relative numbers of different odor-sensing neurons on the basis of how active these neurons are.
