    Double-μPeriscope, a tool for multilayer optical recordings, optogenetic stimulations or both

    Mototaka Suzuki, Jaan Aru, Matthew E Larkum
    Interactions between near but distinct (<1 mm) structures such as cortical layers in the rodent brain can be studied by a new micro-optical tool that is low-cost and capable of multilayer optical recordings, optogenetic stimulations, or both.

    Mortality: A comprehensive look at the COVID-19 pandemic death toll

    Lone Simonsen, Cecile Viboud
    COVID-19 ‘excess mortality’ has been estimated for more than 100 countries and shows a dramatic death toll in many countries.

    B cell receptor and Toll-like receptor signaling coordinate to control distinct B-1 responses to both self and the microbiota

    Lieselotte SM Kreuk, Meghan A Koch ... Gregory M Barton
    Microbial-sensing TLRs drive responses to the microbiota, while nucleic-acid sensing TLRs control responses to endogenous ligands, revealing novel regulation of B-1a responses through integrated BCR/TLR mediated activation.

    Opto-RhoGEFs, an optimized optogenetic toolbox to reversibly control Rho GTPase activity on a global to subcellular scale, enabling precise control over vascular endothelial barrier strength

    Eike K Mahlandt, Sebastián Palacios Martínez ... Joachim Goedhart
    Optogenetic activation of Rho GTPases provides spatiotemporal control over endothelial cell shape and enables control over endothelial barrier function by manipulating the cell-cell overlap with blue light.

    Striking parallels between dorsoventral patterning in Drosophila and Gryllus reveal a complex evolutionary history behind a model gene regulatory network

    Matthias Pechmann, Nathan James Kenny ... Siegfried Roth
    Crucial functions of Toll signalling during dorsoventral axis formation might have evolved convergently in flies and crickets.

    Robust and Efficient Assessment of Potency (REAP) as a quantitative tool for dose-response curve estimation

    Shouhao Zhou, Xinyi Liu ... J Jack Lee
    A novel approach together with a user-friendly web-based analytic tool, coined 'REAP', was proposed to improve the quantitative assessment of dose-response relationship and drug potency.

    OGT binds a conserved C-terminal domain of TET1 to regulate TET1 activity and function in development

    Joel Hrit, Leeanne Goodrich ... Barbara Panning
    The epigenetic regulator TET1 is regulated by the nutrient-sensing enzyme OGT in vitro and in cells.

    Decoding the neural mechanisms of human tool use

    Jason P Gallivan, D Adam McLean ... Jody C Culham
    Imaging experiments reveal that some brain regions do not distinguish between actions performed using tools and those performed using the hands, while others represent these two types of action separately.

    Empathy: Exploring the impact of violence in video games

    Nicolas Roy, Michel-Pierre Coll
    Playing a violent game for a few weeks did not alter neural and behavioral responses to the pain of others in inexperienced male gamers.
