    Nutrient levels and trade-offs control diversity in a serial dilution ecosystem

    Amir Erez et al.
    Whereas theories of ecological diversity mostly consider continuously supplied nutrients, a seasonal model uncovers a general mechanism that controls diversity and reconciles conflicting experimental findings.

    Shadow enhancers can suppress input transcription factor noise through distinct regulatory logic

    Rachel Waymack et al.
    Proper development depends on establishing precise gene expression patterns in spite of the inherent noise in transcription, shadow enhancers buffer this noise by binding distinct input transcription factors.

    Dissecting the immunosuppressive tumor microenvironments in Glioblastoma-on-a-Chip for optimized PD-1 immunotherapy

    Xin Cui et al.
    A biomimetic and patient-specific Glioblastoma-on-a-Chip microphysiological system provides an avenue for personalized screening of PD-1 immunotherapy and novel combinational therapies that maximize therapeutic outcomes in Glioblastoma patients.

    Speciation and the developmental alarm clock

    Asher D Cutter, Joanna D Bundus
    Integrating speciation genetics with ontogeny can identify predictable rules in the molecular evolution of developmental pathways and in the accumulation of reproductive isolation as genomes diverge.

    Non-thalamic origin of zebrafish sensory nuclei implies convergent evolution of visual pathways in amniotes and teleosts

    Solal Bloch et al.
    Mesencephalic origin of the zebrafish thalamocortical-like visual projection neurons indicates independent evolution of tectofugal visual pathways in amniotes and teleosts.

    Underground isoleucine biosynthesis pathways in E. coli

    Charles AR Cotton et al.
    Upon deletion of threonine deaminases, biosynthesis of isoleucine is rescued by two promiscuous reactions, one emerges under aerobic conditions and the other is naturally active under anaerobic conditions.

    Genomic architecture and evolutionary antagonism drive allelic expression bias in the social supergene of red fire ants

    Carlos Martinez-Ruiz et al.
    Analyses of allelic- and socially-biased gene expression reveal that suppressed recombination causes most of the expression differences in the social supergene, with only few differences due to socially antagonistic selection.

    Why is cyclic dominance so rare?

    Hye Jin Park et al.
    A mathematical model for a popular biological diversity mechanism, cyclic dominance, is more likely to emerge by assembly than by evolutionary diversification, which rationalizes why few empirically studies find it.

    Geometric models for robust encoding of dynamical information into embryonic patterns

    Laurent Jutras-Dubé et al.
    Propagation, speed and shapes of genetic waves of expression during development can be modeled by a simple interplay between two transcriptional modules (dynamic/static), which explains robustness and precision of patterning.
