    Decoding hierarchical control of sequential behavior in oscillatory EEG activity

    Atsushi Kikumoto, Ulrich Mayr
    Mental codes that track our position within complex, behavioral sequences, have been hard to pin down empirically, but can be identified and traced over time using oscillatory EEG activity.

    Statistical context dictates the relationship between feedback-related EEG signals and learning

    Matthew R Nassar et al.
    The P300, an electroencephalography (EEG) component known to be evoked by surprising events, predicts learning in a bidirectional manner that depends critically on the surrounding statistical context.

    The plant pathogen Pseudomonas aeruginosa triggers a DELLA-dependent seed germination arrest in Arabidopsis

    Hicham Chahtane et al.
    Arabidopsis seed germination can be repressed by a Pseudomonas factor.

    A Tad-like apparatus is required for contact-dependent prey killing in predatory social bacteria

    Sofiene Seef et al.
    First identification of the molecular determinants driving contact-dependent predation in Myxococcus..

    A chimeric nuclease substitutes a phage CRISPR-Cas system to provide sequence-specific immunity against subviral parasites

    Zachary K Barth et al.
    Horizontal transfer of a sequence-specific DNA-binding domain allows a virus to destroy its subviral parasite and overcome parasite-mediated restriction.

    Non-canonical RNA-directed DNA methylation participates in maternal and environmental control of seed dormancy

    Mayumi Iwasaki et al.
    Seed-specific and cold-induced DNA methylation is deposited in the seed progeny to form a transient and transgenerational memory of past environmental conditions to optimize seed germination timing.
    1. Neuroscience

    Balancing model-based and memory-free action selection under competitive pressure

    Atsushi Kikumoto, Ulrich Mayr
    People compete by trying to outsmart their opponents as long as they win, but show random behavior, and neural signs of suppressing knowledge about opponents’ strategies, when they lose.

    Combinations of maternal-specific repressive epigenetic marks in the endosperm control seed dormancy

    Hikaru Sato et al.
    Analyses of cell type-specific data show that the maternal alleles of genes related to establishing and breaking seed dormancy are suppressed by different combinations of epigenetic marks in the endosperm of Arabidopsis.

    An ABA-GA bistable switch can account for natural variation in the variability of Arabidopsis seed germination time

    Katie Abley et al.
    Arabidopsis shows extensive genetic diversity in germination time distributions, which can be explained by the underlying ABA/GA network functioning as a noisy bistable switch.

    The causal role of the somatosensory cortex in prosocial behaviour

    Selene Gallo et al.
    A combination of human imaging and brain stimulation techniques show that the somatosensory cortex is essential to prosocial decision making, by transforming observed pain in accurate perception of others' distress.
