    Brain representations of motion and position in the double-drift illusion

    Noah J Steinberg, Zvi N Roth ... Elisha Merriam
    The 'double-drift' illusion involves integration of retinal and non-retinal signals in the human visual cortex, providing evidence for a perceptual representation that incorporates extraretinal information.

    High-resolution mapping reveals hundreds of genetic incompatibilities in hybridizing fish species

    Molly Schumer, Rongfeng Cui ... Peter Andolfatto
    Genetic incompatibilities are common and widely distributed throughout the genomes of swordtail fish, and prevent the regions of the genome around them from being exchanged between different species.

    Removing physiological motion from intravital and clinical functional imaging data

    Sean C Warren, Max Nobis ... Paul Timpson
    Image-based motion correction enables the use of fluorescence lifetime and other functional imaging modalities in an intravital and clinical context in the presence of physiological motion.
    1. Neuroscience

    Unifying network model links recency and central tendency biases in working memory

    Vezha Boboeva, Alberto Pezzotta ... Athena Akrami
    Seemingly disparate working memory biases, including short-term serial and contraction biases, may arise from a common mechanism via the interaction of multiple networks, each operating over a distinct timescale.

    An evolutionary model identifies the main evolutionary biases for the evolution of genome-replication profiles

    Rossana Droghetti, Nicolas Agier ... Marco Cosentino Lagomarsino
    Mathematical modeling and data analysis show that, over evolutionary times, the yeast temporal program of replication strives to avoid stalling events and minimize interference between neighbor origins.
    1. Neuroscience

    Multiple decisions about one object involve parallel sensory acquisition but time-multiplexed evidence incorporation

    Yul HR Kang, Anne Löffler ... Michael N Shadlen
    When making two decisions about one object, two streams of information can be acquired in parallel but must be incorporated into the two decisions serially, consistent with a central bottleneck.

    Evolution of the gene regulatory network of body axis by enhancer hijacking in amphioxus

    Chenggang Shi, Shuang Chen ... Guang Li
    The gene regulatory network of Nodal signaling, underpinning body axes patterning, was evolved specifically in cephalochordate lineage.

    Evidence accumulation, not ‘self-control’, explains dorsolateral prefrontal activation during normative choice

    Cendri A Hutcherson, Anita Tusche
    A computational model of decision making suggests that the dorsolateral prefrontal cortex's role in self-control is more associated with evidence accumulation processes than with inhibition or modulation of value.
    1. Neuroscience

    Velocity coupling of grid cell modules enables stable embedding of a low dimensional variable in a high dimensional neural attractor

    Noga Mosheiff, Yoram Burak
    The neural representation of position in the medial entorhinal cortex may be stabilized by synaptic connectivity across modules, which enforces coherent updates in their states.

    Robust membrane protein tweezers reveal the folding speed limit of helical membrane proteins

    Seoyoon Kim, Daehyo Lee ... Duyoung Min
    An exceedingly low speed limit was estimated for a helical hairpin formation by analyzing hours-long, incessant structural transitions.
