    Stoichiometric interactions explain spindle dynamics and scaling across 100 million years of nematode evolution

    Reza Farhadifar, Che-Hang Yu ... Daniel J Needleman
    Stoichiometric interactions between microtubules and cortical force-generators set spindle size, position and dynamics, and its scaling with cell size in nematode species.

    Quantifying antibody kinetics and RNA detection during early-phase SARS-CoV-2 infection by time since symptom onset

    Benny Borremans, Amandine Gamble ... James O Lloyd-Smith
    A meta-analysis shows that seroconversion of antibodies against SARS-CoV-2 is not affected by disease severity and finds higher viral RNA detection probability in lower respiratory tract and fecal samples.

    Plasticity and evolutionary convergence in the locomotor skeleton of Greater Antillean Anolis lizards

    Nathalie Feiner, Illiam SC Jackson ... Tobias Uller
    A comparative and experimental research refutes the controversial hypothesis that plasticity played a major role in the convergent evolution of Anolis ecomorphs.

    Spectral clustering of risk score trajectories stratifies sepsis patients by clinical outcome and interventions received

    Ran Liu, Joseph L Greenstein ... Raimond L Winslow
    Spectral clustering applied to risk trajectories of sepsis patients discovered four distinct clusters stratified by risk of septic shock, mortality, and treatments received prior to an abrupt physiological transition.

    Nutrient status shapes selfish mitochondrial genome dynamics across different levels of selection

    Bryan L Gitschlag, Ann T Tate, Maulik R Patel
    Food supply and nutrient stress tolerance coordinately shape the multilevel selection dynamics of a mitochondrial cheater by promoting cheater persistence at both within-host and between-host levels of selection.

    Tuning movement for sensing in an uncertain world

    Chen Chen, Todd D Murphey, Malcolm A MacIver
    Animals work in a world full of surprises, where using energy to position sensors proportional to the location's expected information avoids the pitfalls of positioning them at the information maxima.

    Empathic pain evoked by sensory and emotional-communicative cues share common and process-specific neural representations

    Feng Zhou, Jialin Li ... Benjamin Becker
    Machine learning analyses reveal that the observation of acute pain inflictions and facial expressions of pain evoke shared pain-specific neural representations.

    An ER translocon for multi-pass membrane protein biogenesis

    Philip T McGilvray, S Andrei Anghel ... Robert J Keenan
    A set of ER-localized membrane proteins whose loss causes developmental diseases in humans, assemble with Sec61 into a translocon that facilitates the biogenesis of hundreds of different multi-pass membrane proteins.

    Activation of astrocytes in hippocampus decreases fear memory through adenosine A1 receptors

    Yulan Li, Lixuan Li ... Yan-Qin Yu
    A new strategy of memory consolidation disruption based on astrocyte and purinergic signaling, which leads to persistent fear memory attenuation accompanied by reduced fear-related anxiety behavior.

    The flagellar motor of Vibrio alginolyticus undergoes major structural remodeling during rotational switching

    Brittany L Carroll, Tatsuro Nishikino ... Jun Liu
    In situ structures of the flagellar motors genetically docked in CCW and CW rotational states reveal major rearrangement that facilitates rotational switch in Vibrio alginolyticus..
