    One-shot learning and behavioral eligibility traces in sequential decision making

    Marco P Lehmann et al.
    Human learning relies on short-term memories (eligibility traces) which provide a mechanism to reinforce sequences of actions from a single reward (one-shot).

    A Drosophila model of neuronal ceroid lipofuscinosis CLN4 reveals a hypermorphic gain of function mechanism

    Elliot Imler et al.
    Genetic analysis of a CLN4 Drosophila model suggests that the disease-causing alleles act as dominant gain of function mutations that cause CSPα oligomerization and impair secretory and prelysosomal trafficking.

    Gradient-independent Wnt signaling instructs asymmetric neurite pruning in C. elegans

    Menghao Lu, Kota Mizumoto
    Genetic analyses revealed the critical role of local Wnt in neuronal patterning by instructing neurite pruning.

    Extensive impact of low-frequency variants on the phenotypic landscape at population-scale

    Téo Fournier et al.
    Genome-wide association studies on a diallel yeast panel revealed the relevance of low-frequency variants on the phenotypic diversity and consequently on the missing heritability at a population-scale.

    Punishment insensitivity emerges from impaired contingency detection, not aversion insensitivity or reward dominance

    Philip Jean-Richard-dit-Bressel et al.
    Behavioral analyses show that individuals insensitive to punishment are afraid of aversive events, they are simply unable to change their behaviour to avoid them.

    Cyclin-dependent kinase 5 (CDK5) regulates the circadian clock

    Andrea Brenna et al.
    Cyclin-dependent kinase 5 regulates the circadian clock involving phosphorylation of the PER2 protein.

    Drosophila PSI controls circadian period and the phase of circadian behavior under temperature cycle via tim splicing

    Lauren E Foley et al.
    A screen targeting RNA-associated proteins reveals that PSI regulates timeless alternative splicing and thus controls the period of Drosophila circadian behavior and its phase under temperature cycles.

    Biophysical and physiological processes causing oxygen loss from coral reefs

    Cynthia B Silveira et al.
    Coral reef heterotrophic bacteria and fleshy macroalgae cause oxygen loss from reef systems through microbial biomass accumulation and ebullition from algae surfaces.

    Chronic muscle weakness and mitochondrial dysfunction in the absence of sustained atrophy in a preclinical sepsis model

    Allison M Owen et al.
    Sepsis-induced long-term muscle weakness was reproduced using a refined murine model, which was accompanied by mitochondrial dysfunction in the absence of sustained atrophy, suggesting the promise of mitochondria-targeted post-sepsis therapies.
