    Gut bacterial aggregates as living gels

    Brandon H Schlomann, Raghuveer Parthasarathy
    A theory of gut bacterial aggregation produces a cluster size distribution that matches that of several strains observed in zebrafish, suggesting principles generally applicable to the vertebrate gut.

    Evolution of irreversible somatic differentiation

    Yuanxiao Gao et al.
    Irreversible differentiation into somatic cells is evolutionarily optimal if changing cell phenotype is costly, a few somatic cells already improve the organism's performance, and the organism is large enough.

    Secondary metabolites of Hülle cells mediate protection of fungal reproductive and overwintering structures against fungivorous animals

    Li Liu et al.
    Xanthones produced by the filamentous fungus Aspergillus nidulans protect its sexual structures from predation by arthropods.

    Polygenic Screening: What’s the use?

    Jason M Fletcher et al.
    A theoretical framework predicts that using polygenic screening to select embryos against traits that depend on many genes has few benefits.

    Switch-like and persistent memory formation in individual Drosophila larvae

    Amanda Lesar et al.
    A new computer controlled behavioral assay and integrated training chamber for individual Drosophila larvae shows that larvae learn all at once and create long-term memories that last overnight.

    Optimal plasticity for memory maintenance during ongoing synaptic change

    Dhruva V Raman, Timothy O'Leary
    Simple mathematical reasoning shows that the large amount of synaptic turnover seen in many parts of the brain is in fact optimal for memory retention.

    A projectome of the bumblebee central complex

    Marcel Ethan Sayre et al.
    Serial-section electron microscopy uncovers the intricate neural network of the bumblebee central complex, revealing highly conserved projection patterns as well as novel circuit elements potentially unique to bees.

    A beta-glucosidase of an insect herbivore determines both toxicity and deterrence of a dandelion defense metabolite

    Meret Huber et al.
    An insect digestive enzyme metabolizes a plant defense compound and thereby modulates herbivore performance and host plant choice, which in turn may alter plant defense evolution in nature.

    ‘Fearful-place’ coding in the amygdala-hippocampal network

    Mi-Seon Kong et al.
    By recording simultaneous spike trains from fear-responsive basal amygdala (BA) and place-responsive dorsal hippocampus (dHPC) neurons in rats foraging for food in a risky predatory situation, a novel BA-dHPC circuit coding mechanism for interfacing danger and place information was revealed.

    Social-like responses are inducible in asocial Mexican cavefish despite the exhibition of strong repetitive behavior

    Motoko Iwashita, Masato Yoshizawa
    A new tracking method revealed the social-like interactions in the Mexican blind cavefish, which was thought to be evolutionarily lost, and also demonstrated its mammal-like antagonistic association between the social-like interaction and repetitive behavior.
