    A gradient of Wnt activity positions the neurosensory domains of the inner ear

    Magdalena Żak, Nicolas Daudet
    Manipulations of Wnt signalling in the chicken embryo reveal how it controls in a dose-dependent manner the formation of the neurosensory territories of the early developing inner ear.

    AI-driven automated discovery tools reveal diverse behavioral competencies of biological networks

    Mayalen Etcheverry, Clément Moulin-Frier ... Michael Levin
    A novel methodology, using diversity search AI algorithms, for exploring the space of possible behaviors of gene regulatory networks, from the perspective of generic problem-solving agents navigating their environment.

    Response to Nodal morphogen gradient is determined by the kinetics of target gene induction

    Julien Dubrulle, Benjamin M Jordan ... Alexander F Schier
    A kinetic model of morphogen interpretation is more suitable than classic threshold or ratchet models to understand how a signal gradient generates different target gene expression patterns.

    Presynaptic Rac1 controls synaptic strength through the regulation of synaptic vesicle priming

    Christian Keine, Mohammed Al-Yaari ... Samuel M Young Jr
    A combination of genetic, electrophysiological, and modeling approaches reveals that presynaptic Rac1 is a key molecule that controls synaptic strength and plasticity by regulating the synaptic vesicle cycle steps controlling the number of fusion competent synaptic vesicles.

    Combining agent-based, trait-based and demographic approaches to model coral-community dynamics

    Bruno Sylvain Carturan, Jason Pither ... Lael Parrott
    A new agent-based model enables predicting how coral species richness and functional diversity affect the functioning and resilience of coral reef ecosystems.

    Hypoxia-induced tracheal elasticity in vector beetle facilitates the loading of pinewood nematode

    Xuan Tang, Jiao Zhou ... Jianghua Sun
    An insect-transmissible plant pathogen, Bursaphelenchus xylophilus, uniquely excavates hypoxia to increase vector capacity via Muc91C-enhanced elasticity of tracheal tubes.

    Fetal and neonatal hematopoietic progenitors are functionally and transcriptionally resistant to Flt3-ITD mutations

    Shaina N Porter, Andrew S Cluster ... Jeffrey A Magee
    Age-specific transcriptional responses to Flt3-ITD and cooperating Flt3/Runx1 mutations cause hematopoietic stem cell depletion and myeloid progenitor expansion during adult, but not fetal/neonatal, stages of development.

    scRNA-sequencing in chick suggests a probabilistic model for cell fate allocation at the neural plate border

    Alexandre P Thiery, Ailin Leticia Buzzi ... Andrea Streit
    Neural plate border cells co-express neural, neural crest, and placodal transcriptional programs before cell fate decisions occur and are transcriptionally heterogeneous along the antero-posterior and medial-lateral axis.

    High potency of sequential therapy with only β-lactam antibiotics

    Aditi Batra, Roderich Roemhild ... Hinrich Schulenburg
    Sequential therapy with only β-lactam antibiotics achieves surprisingly high potency by exploiting both low rates of spontaneous resistance emergence and low rates of spontaneous cross-resistance among the drugs in sequence.

    Ryanodine receptor 2 inhibition reduces dispersion of cardiac repolarization, improves contractile function, and prevents sudden arrhythmic death in failing hearts

    Pooja Joshi, Shanea Estes ... Swati Dey
    Inhibition of RyR2 hyperactivity with dantrolene not only prevents VT/VF and SCD but also heart failure by mitigating calcium dysfunction in pressure-overloaded hearts.
