    Efficient mate finding in planktonic copepods swimming in turbulence

    François-Gaël Michalec et al.
    Calanoid copepods achieve efficient mate finding in turbulence through active swimming and turbulence advection, indicating that reproduction is not restricted to spatial and temporal windows of calm hydrodynamic conditions.

    Olfactory Navigation: Tempo is the key

    Antonio Celani
    Walking flies find the source of attractive odors by changing how frequently they stop and turn in response to the smell.

    Walking Drosophila navigate complex plumes using stochastic decisions biased by the timing of odor encounters

    Mahmut Demir et al.
    Visualized odor encounters show that Drosophila navigate spatiotemporally complex odor plumes using random walks biased by the timing of brief and unpredictable odor encounters.

    Social interactions drive efficient foraging and income equality in groups of fish

    Roy Harpaz, Elad Schneidman
    Analysis and modeling of group behavior of adult zebrafish shows that a specialized social interaction mechanism increases foraging efficiency and equality within groups, under a variety of environmental conditions.

    Tuning movement for sensing in an uncertain world

    Chen Chen et al.
    Animals work in a world full of surprises, where using energy to position sensors proportional to the location's expected information avoids the pitfalls of positioning them at the information maxima.

    Lack of airway submucosal glands impairs respiratory host defenses

    Lynda S Ostedgaard et al.
    Submucosal glands are critical for two key respiratory host defenses, bactericidal activity and mucociliary transport, in an animal model that has lungs like humans.

    Calcium dynamics regulating the timing of decision-making in C. elegans

    Yuki Tanimoto et al.
    A series of quantitative behavioural and opto-physiological analyses using a novel robot microscope system reveals that C. elegans computes the time-differential and time-integral of sensory information for decision-making during olfactory navigation.

    Transcriptional networks specifying homeostatic and inflammatory programs of gene expression in human aortic endothelial cells

    Nicholas T Hogan et al.
    An integrative genome-wide approach supports a direct and collaborative role of ETS and AP-1 transcription factors in maintaining endothelial cell-specific and anti-inflammatory gene expression programs.
