    Tuning of feedforward control enables stable muscle force-length dynamics after loss of autogenic proprioceptive feedback

    Joanne C Gordon et al.
    Running guinea fowl maintain stable running after loss of the stretch reflex in a major ankle extensor muscle, by increasing feedforward muscle activation to maintain ankle stiffness and work output.

    Vestigial auriculomotor activity indicates the direction of auditory attention in humans

    Daniel J Strauss et al.
    Recordings of ear muscles in humans show that ears attempt to pivot in the direction that requires attention.

    The dynamic transmission of positional information in stau- mutants during Drosophila embryogenesis

    Zhe Yang et al.
    In stau-mutants, the Hunchback boundary shifts posteriorly by 10% EL but shows comparable variability to that of the wild type in short time windows in nuclear cycle 14.

    Predicting geographic location from genetic variation with deep neural networks

    CJ Battey et al.
    Neural networks allow fast and accurate prediction of individual spatial locations from genotypes or sequencing data.

    Vessel noise levels drive behavioural responses of humpback whales with implications for whale-watching

    Kate R Sprogis et al.
    Controlled exposure experiments reveal that underwater vessel noise level from a motorised vessel is an adequate driver of behavioural disturbance in humpback whales.

    Inhibition stabilization is a widespread property of cortical networks

    Alessandro Sanzeni et al.
    The strongly coupled theoretical regime describes the function of mouse sensory and motor cortical areas.

    Synaptotagmin-1 is the Ca2+ sensor for fast striatal dopamine release

    Aditi Banerjee et al.
    Genetic and electrophysiological analyses reveal calcium-triggering mechanisms for dopamine release in the striatum that may enable fast and slow dopamine coding.

    Slightly beneficial genes are retained by bacteria evolving DNA uptake despite selfish elements

    Bram van Dijk et al.
    Horizontal gene transfer (HGT) helps slightly beneficial genes persist in microbial populations, incentivising cells to invest in costly DNA uptake, even in the presence of harmful selfish genetic elements.

    Cohesin and condensin extrude DNA loops in a cell cycle-dependent manner

    Stefan Golfier et al.
    Reconstitution of DNA loop extrusion in cellular contexts using Xenopus egg extracts shows that condensin extrudes DNA loops non-symmetrically in metaphase, whereas cohesin extrudes DNA loops symmetrically in interphase.

    Controlling motor neurons of every muscle for fly proboscis reaching

    Claire E McKellar et al.
    A new collection of fly strains comprehensively targets the motor neurons of the proboscis, allowing separate control of every muscle to determine how this appendage achieves flexible, directed reaching.
