    Overtone focusing in biphonic tuvan throat singing

    Christopher Bergevin et al.
    In light of the mysteries underlying the biphonic nature of Tuvan throat song, information from multiple modalities is combined to explain how this remarkable phenomenon is achieved biomechanically.

    Ventrolateral periaqueductal gray neurons prioritize threat probability over fear output

    Kristina M Wright, Michael A McDannald
    Single-unit activity in the ventrolateral periaqueductal gray, a brain region implicated in organizing fear output, is found to reflect threat probability, a more versatile threat signal.

    A causal role for the precuneus in network-wide theta and gamma oscillatory activity during complex memory retrieval

    Melissa Hebscher et al.
    Inhibitory noninvasive stimulation to the precuneus disrupts theta and gamma oscillatory coupling between medial temporal lobes and neocortical regions during complex personal memory retrieval.

    Protein quality control in the nucleolus safeguards recovery of epigenetic regulators after heat shock

    Maria Azkanaz et al.
    Heat shock induces relocalization of epigenetic modifiers to the nucleolus, which acts as a dedicated protein quality control center that is indispensable for recovery of epigenetic regulators and epigenetic modifications.

    The nature of the animacy organization in human ventral temporal cortex

    Sushrut Thorat et al.
    The animacy organization in human ventral visual cortex is driven by both the presence of animal-diagnostic visual features and the psychological property of agency.

    Interneuronal mechanisms of hippocampal theta oscillations in a full-scale model of the rodent CA1 circuit

    Marianne J Bezaire et al.
    Spontaneous theta oscillations and interneuron-specific phase preferences emerge spontaneously in a full-scale model of the isolated hippocampal CA1 subfield, corroborating and extending recent experimental findings.

    Differential impact of self and environmental antigens on the ontogeny and maintenance of CD4+ T cell memory

    Thea Hogan et al.
    Comparing mice in clean and dirty environments reveals that environment drives initial establishment and size of T cell memory compartments, but not their maintenance in adults.

    The Mla pathway in Acinetobacter baumannii has no demonstrable role in anterograde lipid transport

    Matthew J Powers et al.
    An outer membrane vesicle pulse-chase assay demonstrates that the Acinetobacter baumannii Mla system is a retrograde lipid transporter.

    Evidence from a natural experiment that malaria parasitemia is pathogenic in retinopathy-negative cerebral malaria

    Dylan S Small et al.
    The sickle cell trait strongly protects against not only retinopathy-positive cerebral malaria but also retinopathy-negative cerebral malaria, providing evidence that malarial parasites also contribute to retinopathy-negative cerebral malaria and are not innocent bystanders.

    A roadmap for gene functional characterisation in crops with large genomes: Lessons from polyploid wheat

    Nikolai M Adamski et al.
    The development of genomic tools and publicly available resources in polyploid wheat provides a framework to understand biologically important traits in crops with large genomes.
