    The structure of species discrimination signals across a primate radiation

    Sandra Winters et al.
    Machine learning and experimental tests of receiver bias identify signal components critical to correct species classification in guenons, linking face pattern diversity to selection for species discrimination.
  1. The benefits of new brain cells: an interview with Antonia Marín-Burgin

    Antonia Marín-Burgin is a Group Leader at the IBioBA-CONICET-MPSP Institute in Buenos Aires. Her research focuses on understanding how the neurons in the hippocampus – an area of the brain associated with navigation and memory formation – interact to form microcircuits.

  2. Peer Review: Searching for the one

    Helga Groll
    The views of peers are important when applying for a faculty position, but so are research plans and being a good 'fit'.

    Addressing the ethical issues raised by synthetic human entities with embryo-like features

    John Aach et al.
    Guidelines governing research into embryos need to be updated in a way that reflects the moral status of synthetic human entities generated using the methods of synthetic biology.

    Brain and Behavior: Assessing reproducibility in association studies

    Hugo Schnack
    Research that links brain structure with behavior needs more data, better analyses, and more intelligent approaches.

    Independent evolution of ancestral and novel defenses in a genus of toxic plants (Erysimum, Brassicaceae)

    Tobias Züst et al.
    A gain-of-function in a new chemical defense resulted in no trade-offs and and independent evolution between novel and ancestral defenses, suggesting low redundancy among different defensive chemicals.

    Asymmetrical diversification of the receptor-ligand interaction controlling self-incompatibility in Arabidopsis

    Maxime Chantreau et al.
    In-planta ancestral protein resurrection of the female determinant of self-incompatibility specificity in Arabidopsis halleri demonstrates that two allelic variants currently segregating as distinct receptor-ligand combinations diverged through an asymmetrical process.

    The role of structural pleiotropy and regulatory evolution in the retention of heteromers of paralogs

    Axelle Marchant et al.
    Regulatory evolution allows paralogs to escape from strucural pleiotropy.

    Formation of polarity convergences underlying shoot outgrowths

    Katie Abley et al.
    Models that generate tandem alignments of cell polarities are more readily compatible with the formation of PIN1 polarity patterns in plant leaf buds than the most widely accepted “up-the-gradient” model.
