    Ribosomal mutations promote the evolution of antibiotic resistance in a multidrug environment

    James E Gomez et al.
    Mutations in several components of a bacterial ribosome are shown to broadly decrease antibiotic and stress sensitivity, and readily accessible reversion mutations allow these ribosomal mutations to serve as stepping stones to high level antibiotic resistance.

    CCR5 is a suppressor for cortical plasticity and hippocampal learning and memory

    Miou Zhou et al.
    Repression of the G protein-coupled chemokine receptor CCR5 enhances MAPK/CREB signaling, long-term potentiation, somatosensory cortical plasticity, and learning and memory, while CCR5 over-activation by viral proteins may contribute to HIV-associated cognitive deficits.

    RNA Polymerase II cluster dynamics predict mRNA output in living cells

    Won-Ki Cho et al.
    Quantitative super resolution imaging, in live mammalian cells, reveals a direct relationship between protein clustering dynamics and the number of mRNA transcribed at an endogenous gene locus.

    A circuit motif in the zebrafish hindbrain for a two alternative behavioral choice to turn left or right

    Minoru Koyama et al.
    Competition between neurons on the left and right sides of the brain drives the decision to turn left versus right in zebrafish, and potentially all vertebrates.

    Optical electrophysiology for probing function and pharmacology of voltage-gated ion channels

    Hongkang Zhang et al.
    Optogenetic tools enable sophisticated measurements of a voltage-gated sodium channel implicated in pain, as well as high-throughput screening of candidate channel blockers.

    Intraneural stimulation elicits discrimination of textural features by artificial fingertip in intact and amputee humans

    Calogero Maria Oddo et al.
    Delivering specific patterns of electrical activity to the median nerve of the arm triggers reliable sensations of texture, suggesting that it may ultimately be possible to restore complex tactile information to users of prosthetic limbs.

    IK1 channels do not contribute to the slow afterhyperpolarization in pyramidal neurons

    Kang Wang et al.
    The slow afterhyperpolarization that follows a burst of action potentials is a powerful regulator of neuronal excitability and is not due to IK1 (KCNN4), a member of the SK channel family.

    Whole genome comparison of a large collection of mycobacteriophages reveals a continuum of phage genetic diversity

    Welkin H Pope et al.
    A continuum of genome relationships is discovered through comparative genomics of 627 sequenced mycobacteriophages isolated and characterized in an integrated research/education initiative.

    Extinction risk and conservation of the world’s sharks and rays

    Nicholas K Dulvy et al.
    One-quarter of the Chondrichthyes have an elevated risk of extinction, mainly as a result of overfishing.

    T cell immunodominance is dictated by the positively selecting self-peptide

    Wan-Lin Lo et al.
    The T cell repertoire can display immunodominance to an epitope as a result of optimal positive selection in the thymus by one self-peptide/MHC ligand.
