    Bacterial diet affects the age-dependent decline of associative learning in Caenorhabditis elegans

    Satoshi Higurashi, Sachio Tsukada ... Kentaro Noma
    A screen of lactic acid bacteria reveals that diet modulates the age-dependent decline of thermotaxis behavior in C. elegans without changing the organismal lifespan.

    Increased cortical plasticity leads to memory interference and enhanced hippocampal-cortical interactions

    Irene Navarro Lobato, Adrian Aleman-Zapata ... Lisa Genzel
    Increasing cortical plasticity leads to better one-trial memory but more interference effects on semantic-like memory.

    Affectionate touch and diurnal oxytocin levels: An ecological momentary assessment study

    Ekaterina Schneider, Dora Hopf ... Beate Ditzen
    Affectionate touch in everyday life is linked to lower self-reported burden and is associated with higher endogenous oxytocin levels during times of prolonged stress.

    Self-organization of songbird neural sequences during social isolation

    Emily L Mackevicius, Shijie Gu ... Michale S Fee
    In juvenile songbirds, neural sequences pre-exist tutor exposure, and the process of learning a new song may make use of existing neural sequences as a stable substrate for new behavioral changes.

    Hypermetabolism in mice carrying a near-complete human chromosome 21

    Dylan C Sarver, Cheng Xu ... G William Wong
    Mice carrying a near-complete human chromosome 21 are hypermetabolic and have increased thermogenesis due to sarcolipin overexpression in the skeletal muscle, leading to persistent uncoupling of the sarco(endo)plasmic reticulum Ca2+ ATPase pump activity and heat generation.

    Improved isolation of extracellular vesicles by removal of both free proteins and lipoproteins

    Dmitry Ter-Ovanesyan, Tal Gilboa ... David R Walt
    A novel immunoassay for ApoB-100, the main protein component of lipoproteins, enables the development of methods to enrich extracellular vesicles from human plasma while depleting both lipoproteins and free proteins.

    The Plasmodium falciparum apicoplast cysteine desulfurase provides sulfur for both iron-sulfur cluster assembly and tRNA modification

    Russell P Swift, Rubayet Elahi ... Sean T Prigge
    Plasmodium falciparum apicoplast SufS is required for both iron-sulfur synthesis and tRNA modification by MnmA, a novel paradigm that is likely to apply to other plastid-containing organisms.

    Insights into cargo sorting by SNX32 and its role in neurite outgrowth

    Jini Sugatha, Amulya Priya ... Sunando Datta
    The adaptive SNX32 regulates cargo sorting in neuronal and non-neuronal cells.
    1. Neuroscience

    Dopamine in the dorsal bed nucleus of stria terminalis signals Pavlovian sign-tracking and reward violations

    Utsav Gyawali, David A Martin ... Donna Calu
    Dopamine signaling in the bed nucleus of stria terminalis supports sign-tracking, reinforcer-specific satiety, and encodes reward prediction errors.

    Immune mechanisms underlying COVID-19 pathology and post-acute sequelae of SARS-CoV-2 infection (PASC)

    Sindhu Mohandas, Prasanna Jagannathan ... RECOVER Mechanistic Pathways Task Force
    Immune dysregulation is thought to be a hallmark of long COVID or PASC but there is a need for understanding the underlying mechanisms which drive the disease progression.
