    Precise optical control of gene expression in C elegans using improved genetic code expansion and Cre recombinase

    Lloyd Davis et al.
    A method combining optimised genetic code expansion and optogenetics allows dissection of neural circuits with single-cell precision in freely moving animals.

    Offline replay supports planning in human reinforcement learning

    Ida Momennejad et al.
    fMRI evidence for off-task replay predicts subsequent replanning behavior in humans, suggesting that learning from simulated experience during replay helps update past policies in reinforcement learning.

    NMDA spikes mediate amplification of inputs in the rat piriform cortex

    Amit Kumar et al.
    Dendrites of pyramidal neurons in piriform cortex can initiate NMDA spikes, which may serve to amplify odor responses, and provide combination selectivity underlying 'discontinuous' odor receptive fields in these neurons.

    Glutamate is required for depression but not potentiation of long-term presynaptic function

    Zahid Padamsey et al.
    Electrophysiological and optical analysis of neurotransmitter release at central synapses reveals that glutamate signalling is not required for the long-term potentiation (LTP) of presynaptic function, and instead only promotes presynaptic long-term depression (LTD).

    The age of Homo naledi and associated sediments in the Rising Star Cave, South Africa

    Paul HGM Dirks et al.
    Independent dating techniques have established that the H. naledi fossils are between 236 and 335 thousand years old, indicating that small-brained hominins with relatively primitive body shapes co-existed with our early ancestors in Africa.

    The quantity of CD40 signaling determines the differentiation of B cells into functionally distinct memory cell subsets

    Takuya Koike et al.
    Unveiling a mechanism for the fate decision of B-cell differentiation into two functionally distinct memory B cell subsets.

    Synergy between RecBCD subunits is essential for efficient DNA unwinding

    Rani Zananiri et al.
    A new optical tweezers assay sheds light on the mechanism of cooperation and force generation by the subunits of RecBCD, critical for the repair of double strand breaks in bacteria.

    A novel mode of capping protein-regulation by twinfilin

    Adam B Johnston et al.
    Twinfilin functions as a pro-capping ligand of capping protein, dynamically competing with inhibitory ligands of capping proteinto control cellular actin assembly.

    Integrated externally and internally generated task predictions jointly guide cognitive control in prefrontal cortex

    Jiefeng Jiang et al.
    The dorsolateral prefrontal cortex integrates concurrent externally and internally generated predictions of task demand to guide information processing, while the medial prefrontal cortex corrects its prediction error based on actual task demand.

    Human observers have optimal introspective access to perceptual processes even for visually masked stimuli

    Megan A K Peters, Hakwan Lau
    Despite the widely held belief among researchers in consciousness that healthy observers can show unconscious perception, a study using a novel method to control for response biases finds no evidence for this phenomenon.
