    Firefly genomes illuminate parallel origins of bioluminescence in beetles

    Timothy R Fallon et al.
    The first genomic view of beetle luciferase evolution indicates evolutionary independence of luciferase between fireflies and click-beetles, and provide valuable datasets which will accelerate the discovery of new biotechnological tools.

    Host-selected mutations converging on a global regulator drive an adaptive leap towards symbiosis in bacteria

    M Sabrina Pankey et al.
    Selective forces imposed by the squid animal host drive rapid adaptation of non-native Vibrio fischeri bacteria through convergent mutations of large effect, unmasking preexisting coordinated regulation of symbiosis.

    Diverse deep-sea anglerfishes share a genetically reduced luminous symbiont that is acquired from the environment

    Lydia J Baker et al.
    Environmental transmission is atypical of symbionts that have undergone genome degradation, yet genetically reduced deep-sea anglerfish symbionts likely persist in the deep sea biome in search of a new host.

    Bacterial Protein Secretion: Looking inside an injection system

    Sophie A Howard, Alain Filloux
    The proteins injected by bacteria into eukaryotic organisms can lead to fates as diverse as death and metamorphosis.

    Anti-PD-1 immunotherapy leads to tuberculosis reactivation via dysregulation of TNF-α

    Liku B Tezera et al.
    Immune checkpoint inhibition therapy for cancer paradoxically activates tuberculosis infection, and advanced human cell culture modelling demonstrates excess TNF-α section is the primary driver.

    Mitochondria supply ATP to the ER through a mechanism antagonized by cytosolic Ca2+

    Jing Yong et al.
    ATP enters the endoplasmic reticulum (ER) lumen through an SLC35B1/AXER-dependentCaATiER mechanism, and ATP usage in the ER renders 'anti-Warburg' effect by increasing ATP regeneration from OxPhos while decreasing glycolysis.

    A model symbiosis reveals a role for sheathed-flagellum rotation in the release of immunogenic lipopolysaccharide

    Caitlin A Brennan et al.
    Both beneficial and pathogenic bacteria can use their sheathed flagella during host colonization as a novel toxin-/signal-delivery mechanism.

    Chloroplast acquisition without the gene transfer in kleptoplastic sea slugs, Plakobranchus ocellatus

    Taro Maeda et al.
    The newly opened genome of a kleptoplastic mollusk, Plakobranchus ocellatus, indicated that sequestered plastids retain their activity within the animal cell without horizontal algal gene transfer to the animal nucleus.

    Discovery and characterization of Hv1-type proton channels in reef-building corals

    Gisela Rangel-Yescas et al.
    Proton channels are present in reef-building corals and constitute important molecular players that should help understand calcification and the response of these organisms to ocean acidification.
