    A locally-blazed ant trail achieves efficient collective navigation despite limited information

    Ehud Fonio et al.
    Ants employ a new kind of trail to resolve group-level navigational difficulties in scenarios where the information available to individuals does not suffice.

    Seminal fluid compromises visual perception in honeybee queens reducing their survival during additional mating flights

    Joanito Liberti et al.
    After insemination, honeybee queens experience a rapid reduction in vision and flight performance, consistent with an ongoing sexual conflict over the number of mating flights that queens embark on.

    Conditioning sharpens the spatial representation of rewarded stimuli in mouse primary visual cortex

    Pieter M Goltstein et al.
    Stimulus-reward learning sharpens the local representation of the visual space while leaving the overall retinotopic map intact.

    Body side-specific control of motor activity during turning in a walking animal

    Matthias Gruhn et al.
    Turning in an insect is the combined result of body-side-specific modifications in processing of local sensory feedback, and modification of local central pattern generator activity.

    Positive and negative incentive contrasts lead to relative value perception in ants

    Stephanie Wendt et al.
    Relative value perception, a basic tenant of Behavioural Economics, is demonstrated in an insect, and further shown to be driven by cognitive processes and induced by private and social information.

    Ant collective cognition allows for efficient navigation through disordered environments

    Aviram Gelblum et al.
    When real ants confront the classical 'Ant-in-a-labyrinth' physics problem where a random walker traverses a percolated environment, they employ active extended sensing and collective cognition to outperform passive physical solutions.

    Polygenic Scores: It is time to get real when trying to predict educational performance

    Cecile Janssens
    A study of 3,500 children in the UK shows that data on socioeconomic background and previous educational achievements can better predict how students will perform at school than genetic data.

    Axons: The cost of communication in the brain

    Brian A MacVicar et al.
    Imaging ATP in axons reveals that they rely on glucose from the blood and lactate produced by glial cells as sources of energy.
