    Formicine ants swallow their highly acidic poison for gut microbial selection and control

    Simon Tragust et al.
    Poison acidified crops sanitize food and limit disease transmission while at the same time structuring the gut microbiota and thus contribute to the ecological and evolutionary success of formicine ants.

    Structural basis for the reaction cycle of DASS dicarboxylate transporters

    David B Sauer et al.
    Structures of multiple states of two dicarboxylate transporters explain the conformational changes needed for substrate import.

    Transmission dynamics and control of multidrug-resistant Klebsiella pneumoniae in neonates in a developing country

    Thomas Crellen et al.
    Colonisation with resistant Klebsiella pneumoniae in a Cambodian neonatal unit is driven by person-to-person transmission, transmissibility varies by sequence type, and antibiotic consumption generally increases the risk of acquisition.

    The DNA-binding protein HTa from Thermoplasma acidophilum is an archaeal histone analog

    Antoine Hocher et al.
    In Thermoplasma acidophilum, an archaeon without histones, a DNA-binding protein acquired from bacteria via horizontal gene transfer mediates histone-like chromatin architecture.

    A family of fluoride-specific ion channels with dual-topology architecture

    Randy B Stockbridge et al.
    Efflux of xenobiotic fluoride from microorganisms occurs through a novel family of ion channels with stringent selectivity for fluoride ion and dual-topology molecular architecture.
