    Signed and unsigned reward prediction errors dynamically enhance learning and memory

    Nina Rouhani, Yael Niv
    Throughout learning, both unexpected outcomes and the predictive value of cues modulate learning rate and episodic memory, thereby supporting two seemingly opposing theories of associative learning.

    Distinct clonal evolution of B-cells in HIV controllers with neutralizing antibody breadth

    Deniz Cizmeci, Giuseppe Lofano ... Boris Julg
    Extended somatic hypermutation and clonal evolution associated with antibody neutralization breath in HIV controllers with low plasma viral loads provide promise for HIV vaccine development.

    Complementary biosensors reveal different G-protein signaling modes triggered by GPCRs and non-receptor activators

    Mikel Garcia-Marcos
    Heterotrimeric G-proteins can be switched on not only by G-protein-coupled receptors but also by cytoplasmic proteins, resulting in different signaling mechanisms in cells depending on the specific type of activator.

    The recycling endosome protein Rab25 coordinates collective cell movements in the zebrafish surface epithelium

    Patrick Morley Willoughby, Molly Allen ... Ashley EE Bruce
    Rab25a and Rab25b mutant embryos exhibit epithelial spreading delays during morphogenesis and are characterized by cytokinesis defects leading to cell fusions, heterogeneous epithelial cell sizes, and reduced cortical actomyosin contractility.

    An open label trial of anakinra to prevent respiratory failure in COVID-19

    Evdoxia Kyriazopoulou, Periklis Panagopoulos ... Evangelos J Giamarellos-Bourboulis
    Early suPAR-guided anakinra decreases the risk for severe respiratory failure in SARS-CoV-2 pneumonia and restores the pro-/anti-inflammatory balance.

    Disparate bone anabolic cues activate bone formation by regulating the rapid lysosomal degradation of sclerostin protein

    Nicole R Gould, Katrina M Williams ... Joseph P Stains
    Mechanical loading and the bone anabolic action of parathyroid hormone result in rapid, lysosomal degradation of sclerostin protein, revealing physiologically important post-translational control of this critical regulator of bone formation.

    Global gradients in intertidal species richness and functional groups

    Jakob Thyrring, Lloyd S Peck
    No discernible latitudinal diversity gradient in rocky intertidal α-diversity as local-scale physical and biological processes outweigh global-scale environmental gradients.

    Ancient DNA reveals the lost domestication history of South American camelids in Northern Chile and across the Andes

    Paloma Diaz-Maroto, Alba Rey-Iglesia ... Anders J Hansen
    aDNA revealed a model of domestication where an ancient guanaco population no longer exists, the loss of the ancient vicuña genetic variation in the modern populations, and frequently interbreeding practices.

    Properties of multivesicular release from mouse rod photoreceptors support transmission of single-photon responses

    Cassandra L Hays, Asia L Sladek ... Wallace B Thoreson
    To improve the reliability of transmitting small single-photon voltage responses, rod photoreceptor cells release synaptic vesicles in regularly timed multivesicular events that are exquisitely sensitive to small voltage changes.

    Acquisition of innate odor preference depends on spontaneous and experiential activities during critical period

    Qiang Qiu, Yunming Wu ... C Ron Yu
    A delicate balance of neural activity is required during critical period in establishing innate odor preference.
