    Transverse tubule remodeling enhances Orai1-dependent Ca2+ entry in skeletal muscle

    Antonio Michelucci, Simona Boncompagni ... Feliciano Protasi
    Structural and functional analyses show that transverse tubule association with stacks of sarcoplasmic reticulum enhances Orai1-dependent Ca2+ entry to replenish Ca2+ stores, maintain Ca2+ release, and maximize force during exercise.

    The pioneer factor OCT4 requires the chromatin remodeller BRG1 to support gene regulatory element function in mouse embryonic stem cells

    Hamish W King, Robert J Klose
    The chromatin remodeller BRG1 is recruited to pluripotency-associated gene regulatory elements by the pioneer transcription factor OCT4 to support further transcription factor binding and gene regulation.

    Metabolic stress is a primary pathogenic event in transgenic Caenorhabditis elegans expressing pan-neuronal human amyloid beta

    Emelyne Teo, Sudharshan Ravi ... Jan Gruber
    Metabolic defects following expression of Aβ1-42 in nematode neurons are partially caused by inactivation of alpha-ketoglutarate dehydrogenase and can be rescued by Metformin.

    Revisiting the guidelines for ending isolation for COVID-19 patients

    Yong Dam Jeong, Keisuke Ejima ... Marco Ajelli
    Compared with the approach isolating COVID-19 patients for a fixed period, the approach using repeated PCR testing mitigates unnecessarily lengthy isolation of patients while minimizing the risk of further transmission.

    Sensory dynamics of visual hallucinations in the normal population

    Joel Pearson, Rocco Chiou ... Bard Ermentrout
    A new method for inducing, measuring and modelling visual hallucinations in healthy people reveals that hallucinations share common underlying mechanisms with normal sensory perception.

    Narrow equilibrium window for complex coacervation of tau and RNA under cellular conditions

    Yanxian Lin, James McCarty ... Songi Han
    Liquid-liquid phase separation of tau is demonstrated to be an equilibrium state, stable only within a narrow range near physiological conditions, and thus has the capacity to regulate biological processes.

    A shift in anterior–posterior positional information underlies the fin-to-limb evolution

    Koh Onimaru, Shigehiro Kuraku ... Mikiko Tanaka
    A shift in antero-posterior positional information may contribute to the fin-to-limb transformation.

    Cerebellar Purkinje cells control eye movements with a rapid rate code that is invariant to spike irregularity

    Hannah L Payne, Ranran L French ... Jennifer L Raymond
    Patterned optogenetic stimulation and analysis of neural activity provide convergent evidence that cerebellar Purkinje cells drive eye movements with a rapid rate code, without an additional contribution of spike irregularity.
