    Neuronal sequences during theta rely on behavior-dependent spatial maps

    Eloy Parra-Barrero, Kamran Diba, Sen Cheng
    A computational framework and analysis of rodent CA1 data reveals that theta oscillations sequentially sweep through the past, present, and future at a spatial scale that varies with the characteristic speed of the animal.

    Astrocyte aquaporin mediates a tonic water efflux maintaining brain homeostasis

    Cuong Pham, Yuji Komaki ... Dongdong Li
    The water channel AQP4 contributes to a tonic water outflow from brain astrocytes, thereby modulating their volume dynamics and the ambient water homeostasis.

    Plant Trans-Golgi Network/Early Endosome pH regulation requires Cation Chloride Cotransporter (CCC1)

    Daniel W McKay, Heather E McFarlane ... Stefanie Wege
    Cation chloride cotransporter CCC1 has a central function in plant cells and is the missing ion efflux component of the transport circuit necessary to regulate pH in the lumen of the trans-Golgi-network/early endosome, the major cargo hub in plant cells.

    Capping protein regulates endosomal trafficking by controlling F-actin density around endocytic vesicles and recruiting RAB5 effectors

    Dawei Wang, Zuodong Ye ... Jianbo Yue
    CapZ controls actin filament density around immature early endosomes via its C-terminal domain to facilitate the homotypic fusion of the endocytic vesicles, and it functions as a scaffold protein via its N-terminal domain to recruit RAB5 effectors to early endosomes.

    Neural arbitration between social and individual learning systems

    Andreea Oliviana Diaconescu, Madeline Stecy ... Philippe N Tobler
    Arbitration is formalised as the relative precision of predictions afforded by reward and social learning systems and is represented in modality-specific dopaminergic and dopaminoceptive regions, including the midbrain and amygdala.

    Nitric oxide radicals are emitted by wasp eggs to kill mold fungi

    Erhard Strohm, Gudrun Herzner ... Tobias Engl
    To protect their food and themselves against detrimental mould fungi, the eggs of a wasp species synthesize and emit remarkable amounts of gaseous nitrogen oxides that are highly effective antimicrobials.

    Rapid adaptation of endocytosis, exocytosis, and eisosomes after an acute increase in membrane tension in yeast cells

    Joël Lemière, Yuan Ren, Julien Berro
    Within minutes after an abrupt increase in membrane tension, yeast cells reduce their membrane tension by modulating their rate of endocytosis and exocytosis, and adapt their endocytic actin machinery.

    Independent manipulation of histone H3 modifications in individual nucleosomes reveals the contributions of sister histones to transcription

    Zhen Zhou, Yu-Ting Liu ... Jin-Qiu Zhou
    A yeast genetic model for studying the function of sister histones in chromatin dynamics.

    Evolution of cytokine production capacity in ancient and modern European populations

    Jorge Domínguez-Andrés, Yunus Kuijpers ... Mihai G Netea
    Neolithic was a turning point for immune responses in Europeans, favoring tolerance against intracellular pathogens, promoting inflammation against extracellular microbes, and being related to current auto-immune diseases.

    Somatostatin binds to the human amyloid β peptide and favors the formation of distinct oligomers

    Hansen Wang, Lisa D Muiznieks ... Gerold Schmitt-Ulms
    The cyclic neuropeptide somatostatin binds to human Aβ1-42 through an interface that critically relies on a specific tryptophan, thereby blocking the propensity of Aβ to aggregate, a critical step in the pathobiology of Alzheimer's disease.
