    7-Dehydrocholesterol-derived oxysterols cause neurogenic defects in Smith-Lemli-Opitz syndrome

    Hideaki Tomita, Kelly M Hines ... Libin Xu
    A 7-dehydrocholesterol-derived oxysterol in SLOS was found to profoundly impact neurogenesis during cortical development by interacting with glucocorticoid receptor, which points to new therapeutic approaches for SLOS by targeting the activities of this oxysterol.

    A neurogenic signature involving monoamine Oxidase-A controls human thermogenic adipose tissue development

    Javier Solivan-Rivera, Zinger Yang Loureiro ... Silvia Corvera
    A hybrid mouse/human model using mesenchymal progenitor cells reveals dynamics of human adipose tissue development and mechanisms that may enhance human adipose thermogenic capacity.

    Murine blastocysts generated by in vitro fertilization show increased Warburg metabolism and altered lactate production

    Seok Hee Lee, Xiaowei Liu ... Paolo F Rinaudo
    In vitro fertilization-conceived murine embryos show evidence of oxidative and metabolic stress with alteration in lactic acid metabolism.

    Distinct population and single-neuron selectivity for executive and episodic processing in human dorsal posterior cingulate

    Lyndsey Aponik-Gremillion, Yvonne Y Chen ... Brett L Foster
    Invasive recordings from human dorsal posterior cingulate cortex show neural population responses occur for only executive tasks, while single neuron responses occur for specific executive or episodic cognitive tasks.

    Time encoding migrates from prefrontal cortex to dorsal striatum during learning of a self-timed response duration task

    Gabriela C Tunes, Eliezyer Fermino de Oliveira ... Marcelo Bussotti Reyes
    Electrophysiological and pharmacological data provide evidence that the medial prefrontal cortex is essential for rats to learn a timing task, becoming unnecessary later, while the dorsal striatum does not play a role initially, taking over when animals become proficient.

    Ear pinnae in a neotropical katydid (Orthoptera: Tettigoniidae) function as ultrasound guides for bat detection

    Christian A Pulver, Emine Celiker ... Fernando Montealegre-Z
    Located in the legs, the miniaturized katydid ears exhibit cuticular pinnae to only capture high-ultrasonic bat echolocation calls, but katydid also hear their own calls using alternative ear paths, which suggest that their ears operate in a colossal frequency range.

    H3K9me1/2 methylation limits the lifespan of daf-2 mutants in C. elegans

    Meng Huang, Minjie Hong ... Xuezhu Feng
    The depletion of a new class of putative histone methyltransferases, including MET-2, SET-6, SET-19, SET-20, SET-21, SET-32, and SET-33, induced synergistic lifespan extension in daf-2 animals to an average lifespan nearly three times that of wild-type animals.

    Insulin sensitivity in mesolimbic pathways predicts and improves with weight loss in older dieters

    Lena J Tiedemann, Sebastian M Meyhöfer ... Stefanie Brassen
    Insulinergic neuromodulation of hedonic food processing predicts future weight management and improves with weight loss in older overweight dieters.

    Loss of full-length dystrophin expression results in major cell-autonomous abnormalities in proliferating myoblasts

    Maxime RF Gosselin, Virginie Mournetas ... Dariusz C Gorecki
    Loss of full-length dystrophin expression causes significant molecular and functional defects in human and mouse myoblast, thus closing the vicious cycle of DMD pathology.

    Mixed synapses reconcile violations of the size principle in zebrafish spinal cord

    Evdokia Menelaou, Sandeep Kishore, David L McLean
    In the zebrafish spinal cord, mixed synapses contribute to neuronal connectivity and resting excitability, which helps explain violations of the well-known 'size principle' of recruitment.
