    Point of View: Towards a mechanistic foundation of evolutionary theory

    Michael Doebeli et al.
    A description of evolution that is based on birth-death processes, and in which fitness is at most a derived quantity, is advocated.

    Metabolic constraints drive self-organization of specialized cell groups

    Sriram Varahan et al.
    In a developing yeast colony, cells go from homogeneous states to spatially organized, specialized metabolic states, and the new metabolic states depend on resources produced by the original state.

    Homeostatic plasticity fails at the intersection of autism-gene mutations and a novel class of common genetic modifiers

    Özgür Genç et al.
    Forward genetic screens define a novel genetic landscape by which diverse, unrelated autism risk genes may converge to commonly affect the robustness of synaptic transmission.

    An evolutionary recent IFN/IL-6/CEBP axis is linked to monocyte expansion and tuberculosis severity in humans

    Murilo Delgobo et al.
    Mycobacterium tuberculosis exploits an IFN/IL6/CEBP axis linked to monocyte expansion in humans.

    The MADS-box transcription factor PHERES1 controls imprinting in the endosperm by binding to domesticated transposons

    Rita A Batista et al.
    Jumping of transposable elements provides DNA-binding sites for the MADS-box transcription factor PHERES1, allowing the regulation of imprinted genes and other key endosperm development genes.

    The golden mimicry complex uses a wide spectrum of defence to deter a community of predators

    Stano Pekár et al.
    A mimetic complex composed of at least 140 species of ants, wasps, spiders, true bugs and treehoppers, all with conspicuous golden bodies, has been discovered.

    Adaptive tuning of mutation rates allows fast response to lethal stress in Escherichia coli

    Toon Swings et al.
    Population mutation rates are highly flexible and evolvable under extreme stress conditions, matching changes in selective pressure to avoid extinction of the entire population.

    Cortical flow aligns actin filaments to form a furrow

    Anne-Cecile Reymann et al.
    Compressing the actomyosin network by cortical flow causes filaments to align and form a constricting ring.

    Dopamine drives Drosophila sechellia adaptation to its toxic host

    Sofía Lavista-Llanos et al.
    The insect dopaminergic system serves an important function in the regulation of ontogenesis and early development, contributing to the evolutionary processes that limit the ecological niche of Drosophila sechellia.

    Clusters of polymorphic transmembrane genes control resistance to schistosomes in snail vectors

    Jacob A Tennessen et al.
    A region of the Biomphalaria genome, containing highly divergent haplotypes with different combinations of transmembrane genes, strongly impacts whether these snails can transmit parasitic schistosomes.
