    First bone-cracking dog coprolites provide new insight into bone consumption in Borophagus and their unique ecological niche

    Xiaoming Wang et al.
    Fossilized feces (coprolites) of extinct bone-crushing dogs, Borophagus parvus, from late Miocene (6 million years ago) of California demonstrates consumption and preservation of bones in digestive tracts and potential social hunting behavior by these predators.

    Gyrification of the cerebral cortex requires FGF signaling in the mammalian brain

    Naoyuki Matsumoto et al.
    FGF signaling is crucial for gyrus formation, proliferation of outer radial glial cells and expansion of upper layers of the cerebral cortex in gyrencephalic mammals.

    Non-classical amine recognition evolved in a large clade of olfactory receptors

    Qian Li et al.
    Fish trace amine-associated receptors evolved a novel structural motif that enables the detection of chemically diverse amine odors in a non-canonical 'inverted' orientation.

    Mass enhances speed but diminishes turn capacity in terrestrial pursuit predators

    Rory P Wilson et al.
    Increased mass enhances speed but compromises turning capacity in pursuit predators; this has widespread ramifications for the best strategies for predators and prey during chases according to their relative masses.

    Nematophagous fungus Arthrobotrys oligospora mimics olfactory cues of sex and food to lure its nematode prey

    Yen-Ping Hsueh et al.
    Genetic and behavior analyses show that Caenorhabditis nematodes are lured to the predator Arthrobotrys oligospora by olfactory mimicry of food and sex cues.
