    Comment on "Magnetosensitive neurons mediate geomagnetic orientation in Caenorhabditis elegans"

    Lukas Landler, Simon Nimpf ... David A Keays
    Employing blinded controlled methodology we find no evidence for a magnetic sense in the nematode worm Caenorhabditis elegans.

    Magnetosensitive neurons mediate geomagnetic orientation in Caenorhabditis elegans

    Andrés Vidal-Gadea, Kristi Ward ... Jonathan Pierce-Shimomura
    With the aid of a pair of sensory neurons, the nematode worm C. elegans is able to detect the Earth's magnetic field and use it to navigate towards food sources.

    Causal evidence for lateral prefrontal cortex dynamics supporting cognitive control

    Derek Evan Nee, Mark D'Esposito
    Non-invasive brain stimulation tests and refines a model of lateral prefrontal cortex neural dynamics supporting cognitive control.

    Response to comment on "Magnetosensitive neurons mediate geomagnetic orientation in Caenorhabditis elegans"

    Andres Vidal-Gadea, Chance Bainbridge ... Jonathan Pierce-Shimomura
    A reanalysis of data from a challenge by Landler et al. (2018) and our Vidal-Gadea et al. (2015) study reinforce our original finding that C. elegans is a suitable model system to study magnetoreception.

    Inhibition of SARS-CoV-2 polymerase by nucleotide analogs from a single-molecule perspective

    Mona Seifert, Subhas C Bera ... David Dulin
    High-throughput and ultra-stable magnetic tweezers reveal that Remdesivir induces a long-lived backtrack pause upon incorporation by the coronavirus polymerase, and SARS-CoV-2 is able to evade interferon-induced antiviral ddhCTP.

    Rapid stimulus-driven modulation of slow ocular position drifts

    Tatiana Malevich, Antimo Buonocore, Ziad M Hafed
    Slow, continuous changes in eye position when gaze is fixed, previously believed to be random drifts, are shown to exhibit highly systematic and short-latency response characteristics to visual stimuli.

    Cortical excitability controls the strength of mental imagery

    Rebecca Keogh, Johanna Bergmann, Joel Pearson
    Visual and prefrontal cortex excitability predict individual differences in visual imagery strength, and modulating excitability in these cortical regions causally alters the strength of visual imagery.

    Caveolae couple mechanical stress to integrin recycling and activation

    Fidel-Nicolás Lolo, Dácil María Pavón ... Miguel A del Pozo
    Caveolae regulate integrin mechanosensing by establishing a force threshold for activation and recycling.
