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.

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.
Computational analyses quantitatively account for optical refraction at air-water interfaces to enable visual neuroscientists to present distortion-free stimuli to underwater animals.

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.

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.

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.
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.
