    Reconstruction of Par-dependent polarity in apolar cells reveals a dynamic process of cortical polarization

    Kalyn Kono et al.
    Par-complex-dependent cell polarity can be cell-autonomously conferred to non-polar Drosophila S2 cells, unveiling temporal patterns toward the cortical localization of Par-complex aggregates that include a meshwork containing unit segments.

    Elevated synaptic vesicle release probability in synaptophysin/gyrin family quadruple knockouts

    Mathan K Raja et al.
    Synaptophysins and gyrins dampen synaptic strength selectively at low frequencies, hinting that synaptic transmission may play a frequency filtering role in biological computation that is more general than currently envisioned.

    A bipartite iron-dependent transcriptional regulation of the tryptophan salvage pathway in Chlamydia trachomatis

    Nick D Pokorzynski et al.
    Analysis of the atypical tryptophan biosynthetic operon of Chlamydia trachomatis revealed the simultaneous regulation of transcriptional initiation and termination by an iron-dependent repressor, expanding known regulatory mechanisms of this pathway.

    Behavioural and neural signatures of perceptual decision-making are modulated by pupil-linked arousal

    Jochem van Kempen et al.
    A direct relationship between pupil diameter and electrophysiological correlates of attention, sensory stimulus processing and target detection was observed demonstrating that arousal has a substantial influence on perceptual decision-making.

    Connexin-43-dependent ATP release mediates macrophage activation during sepsis

    Michel Dosch et al.
    Autocrine activation of macrophages is modulated by Connexin-43-mediated ATP release in response to TLR-4 and -2 agonists in a P2Y1-dependent manner, ultimately determining sepsis survival.

    Leave-One-Trial-Out, LOTO, a general approach to link single-trial parameters of cognitive models to neural data

    Sebastian Gluth, Nachshon Meiran
    Leave-One-Trial-Out (LOTO) is a general, efficient and easily implementable approach for inferring trial-by-trial measures of computational model parameters in order to link these measures to neural mechanisms.

    Quantitative insights into the cyanobacterial cell economy

    Tomáš Zavřel et al.
    Phototrophic growth laws are elucidated by combining computational modeling and experiments for quantitative evaluation of cellular physiology, morphology and proteome allocation across a wide range of light conditions.

    Emergence of trait variability through the lens of nitrogen assimilation in Prochlorococcus

    Paul M Berube et al.
    In the context of an organism's ecology, physiology, and macroevolutionary history, inheritance and gene loss can yield emergent patterns of trait variability that give the appearance of gene acquisition.

    Hexameric helicase G40P unwinds DNA in single base pair steps

    Michael Schlierf et al.
    Single-molecule FRET experiments reveal that G40P, a DnaB-like helicase, unwinds double-stranded DNA in single base pair steps and its processivity is enhanced by host primase DnaG.

    Humans strategically shift decision bias by flexibly adjusting sensory evidence accumulation

    Niels A Kloosterman et al.
    Decision-makers are able to intentionally control neural excitability to strategically bias sensory evidence accumulation towards the decision bound that maximizes reward within a given ecological context.
