    The genomes of polyextremophilic cyanidiales contain 1% horizontally transferred genes with diverse adaptive functions

    Alessandro W Rossoni, Dana C Price ... Andreas PM Weber
    Horizontal gene transfer (HGT) analysis in polyextremophile red algae (Cyanidiales) provides explanations for the nonexistence of cumulative effects and eukaryotic pangenomes, and highlights differences between HGT and native genes.

    Evolution of extreme resistance to ionizing radiation via genetic adaptation of DNA repair

    Rose T Byrne, Audrey J Klingele ... Michael M Cox
    Experiments on E. coli show that multiple mechanisms contribute to extreme resistance to ionizing radiation in bacteria, with mutations to three genes for DNA repair having a prominent role in one evolved population.

    Structure and in situ organisation of the Pyrococcus furiosus archaellum machinery

    Bertram Daum, Janet Vonck ... Werner Kühlbrandt
    Using both electron cryo-tomography and helical reconstruction, the first structure of the entire archaellum machinery with an assembled filament has been determined, providing the structural basis for our understanding of archaeal motility.

    Ionic selectivity and thermal adaptations within the voltage-gated sodium channel family of alkaliphilic Bacillus

    Paul G DeCaen, Yuka Takahashi ... David E Clapham
    Not all members of the bacteria sodium channel family are sodium channels - those found in Bacillus are highly adaptable and can be converted into many selectivity types.
