    A novel twelve class fluctuation test reveals higher than expected mutation rates for influenza A viruses

    Matthew D Pauly et al.
    A new assay for specific mutational classes provides preciseestimates of the mutation rates and mutational bias for influenza A viruses.

    Adaptive tuning of mutation rates allows fast response to lethal stress in Escherichia coli

    Toon Swings et al.
    Population mutation rates are highly flexible and evolvable under extreme stress conditions, matching changes in selective pressure to avoid extinction of the entire population.

    Mutations that improve efficiency of a weak-link enzyme are rare compared to adaptive mutations elsewhere in the genome

    Andrew B Morgenthaler et al.
    Mutations elsewhere in the genome play critical roles in improving fitness during amplification and divergence of a gene encoding a weak-link enzyme whose inefficiency limits growth rate.

    Moderate nucleotide diversity in the Atlantic herring is associated with a low mutation rate

    Chungang Feng et al.
    The Atlantic herring has the lowest mutation rate yet estimated in a vertebrate species and this partially explains its moderate nucleotide diversity given the large population size.

    Selection on mutators is not frequency-dependent

    Yevgeniy Raynes, Daniel Weinreich
    Contrary to intuition that the evolutionary fate of mutation rate modifying alleles is frequency-dependent, neither the strength nor the sign of selection on modifiers depends on initial frequency.

    Resolving rates of mutation in the brain using single-neuron genomics

    Gilad D Evrony et al.
    The reanalysis of data from a recent study that claimed retrotransposon mutations are ubiquitous in the human brain outlines a general framework for the design and analysis of single-cell genomics studies.

    Non-coding cancer driver candidates identified with a sample- and position-specific model of the somatic mutation rate

    Malene Juul et al.
    A new statistical approach identifies non-coding regulatory regions of genes as driver candidates with recurrent mutations across cancer samples that associate with gene expression, patient survival or mutational phenotype.

    Opposite changes in APP processing and human Aβ levels in rats carrying either a protective or a pathogenic APP mutation

    Marc D Tambini et al.
    APP mutations that either cause or prevent dementia alter APP metabolism in a complex and opposite fashion, suggesting a link between multiple APP processing events, dementia and ageing-dependent cognitive decline.

    Immunodeficiency: Back from the brink of obscurity

    Donald C Vinh
    A mutation in a transcription factor makes people susceptible to Trophyrema whippelii, the bacterium that causes a rare condition called Whipple's disease.
