    Fin whale song evolution in the North Atlantic

    Miriam Romagosa, Sharon Nieukirk ... Mónica A Silva
    The rapid and gradual fin whale songs changes adopted by individuals of a certain area provide evidence of vocal learning in this species, elucidate patterns of song evolution and hints on the limits of song variation.

    Global chromatin mobility induced by a DSB is dictated by chromosomal conformation and defines the HR outcome

    Fabiola García Fernández, Etienne Almayrac ... Emmanuelle Fabre
    A designed system to track homologous recombination (HR) in vivo demonstrates the importance of chromosome organization in the induction of global mobility in response to double-strand breaks and characterizes the role of two types of global motility in HR.

    Independent and interacting value systems for reward and information in the human brain

    Irene Cogliati Dezza, Axel Cleeremans, William H Alexander
    Reward and information are independently optimized in the human prefrontal cortex, while their signals combine in subcortical regions.

    Temporal integration of auxin information for the regulation of patterning

    Carlos S Galvan-Ampudia, Guillaume Cerutti ... Teva Vernoux
    Rhythmic centrifugal waves of auxin traveling through the tissue provides high definition positional information to cells that is not only spatial but also temporal.

    Mfn2 ubiquitination by PINK1/parkin gates the p97-dependent release of ER from mitochondria to drive mitophagy

    Gian-Luca McLelland, Thomas Goiran ... Edward A Fon
    A crucial step during the mitophagy cascade involves the disassembly of connections between mitochondria and the endoplasmic reticulum via the retrotranslocation of Mfn2 tethering complexes by the Parkinson's disease genes PARKIN and PINK1, as well as the ATPase VCP/p97.

    Competition between parallel sensorimotor learning systems

    Scott T Albert, Jihoon Jang ... Reza Shadmehr
    When a common error drives parallel implicit and explicit learning systems, increases in the explicit response will suppress implicit adaptation.

    Humans disrupt access to prey for large African carnivores

    Kirby L Mills, Nyeema C Harris
    The presence of humans induces behavioral modifications in many large carnivore and ungulate species, restructuring spatiotemporal relationships between African predators and their prey.
    1. Neuroscience

    Sensorimotor feedback loops are selectively sensitive to reward

    Olivier Codol, Mehrdad Kashefi ... Paul L Gribble
    Motor performance benefits from rewarding contexts via a non-uniform reduction of response latencies and increase in feedback gains across the feedback loops involved in upper limb motor control.

    Polygenic adaptation after a sudden change in environment

    Laura Katharine Hayward, Guy Sella
    A shift in fitness optimum of a polygenic trait rapidly introduces small frequency differences between alleles with effects aligned with and opposing the shift, which gradually translate into small differences in fixation probability.

    High-density sampling reveals volume growth in human tumours

    Arman Angaji, Michel Owusu ... Johannes Berg
    Spatial genomics reveals the mode of evolution of a tumour based on the positions of mutations in high-resolution samples.
