Fetching an object by means of sending a wave—impossible? Not necessarily. As now demonstrated experimentally, generating waves on a water surface using a set of plungers can cause a floating particle to move counter to the general direction of wave propagation. The effect originates from vorticity creation by steep 3D waves.

Noel et al. show aberrant updating of expectations in three distinct mouse models of autism spectrum disorder. Brain-wide neurophysiology data suggest this stems from excess units encoding deviations from prior mean and a lack of sensory prediction errors in frontal areas.

The meiotic transmissibility and progeny phenotypic influence of graft-mediated epigenetic changes remain unclear. Here, the authors use the msh1 mutant in the rootstock to trigger heritable enhanced growth vigor in Arabidopsis and tomato, and show it is associated with the RNA-directed DNA methylation pathway.

Successful human-AI collaboration could greatly contribute to breast cancer mammographic screening. Here, the authors use a large-scale retrospective mammography dataset to simulate and compare five plausible AI-integrated screening pathways, finding optimal ways in which human-AI collaboration could be implemented in real-world settings.
