    Alcids ‘fly’ at efficient Strouhal numbers in both air and water but vary stroke velocity and angle

    Anthony B Lapsansky, Daniel Zatz, Bret W Tobalske
    Four species of seabird produce efficient propulsive wakes while flying in the air and while swimming underwater suggesting that selection has optimized these species for locomotion in remarkably different fluids.

    Routine single particle CryoEM sample and grid characterization by tomography

    Alex J Noble, Venkata P Dandey ... Bridget Carragher
    Fiducial-less tomography on single particle cryoEM samples reveals that most particles are adsorbed to the air-water interface and allows for researchers to diagnose and solve sample, grid, ice thickness, collection, and processing issues.

    Correcting for physical distortions in visual stimuli improves reproducibility in zebrafish neuroscience

    Timothy W Dunn, James E Fitzgerald
    Computational analyses quantitatively account for optical refraction at air-water interfaces to enable visual neuroscientists to present distortion-free stimuli to underwater animals.

    The return to water in ancestral Xenopus was accompanied by a novel mechanism for producing and shaping vocal signals

    Ursula Kwong-Brown, Martha L Tobias ... Darcy B Kelley
    When ancestral Xenopus returned to water ~170mya, they evolved a new method for producing courtship calls underwater without airflow, using vibrations that also preserve essential acoustic information on species identity.

    Lung evolution in vertebrates and the water-to-land transition

    Camila Cupello, Tatsuya Hirasawa ... Paulo M Brito
    The primitive state of vertebrate lungs is unpaired, evolving to be truly paired in the lineage towards the tetrapods, increasing the pulmonary efficiency during the water-to-land transition.

    The archerfish uses motor adaptation in shooting to correct for changing physical conditions

    Svetlana Volotsky, Opher Donchin, Ronen Segev
    The archerfish adapts with egocentric reference frame to correct for different conditions during shot above water level.

    Extreme suction attachment performance from specialised insects living in mountain streams (Diptera: Blephariceridae)

    Victor Kang, Robin T White ... Walter Federle
    Net-winged midge larvae use suction organs covered in spine-like cuticular protrusions to generate powerful attachment on wet and rough surfaces.

    Midbrain dopamine neurons signal aversion in a reward-context-dependent manner

    Hideyuki Matsumoto, Ju Tian ... Mitsuko Watabe-Uchida
    Dopamine neurons signal value prediction errors (VPEs) integrating information about both reward and aversion, in low reward contexts, whereas VPEs in some dopamine neurons are distorted in high reward contexts.

    Poor air quality is associated with impaired visual cognition in the first two years of life: A longitudinal investigation

    John P Spencer, Samuel H Forbes ... Aarti Kumar
    Infants exposed to poorer air quality showed lower visual working memory at 6 and 9 months and slower visual processing speed from 6 to 21 months, suggesting interventions to improve air quality could improve cognition early in development.
