    Distinct neural contributions to metacognition for detecting, but not discriminating visual stimuli

    Matan Mazor, Karl J Friston, Stephen M Fleming
    Combining psychophysics and functional MRI reveals a qualitative asymmetry in neural engagement when reflecting on whether a stimulus is seen (detection) compared to reflecting on what a stimulus is (discrimination).
    1. Neuroscience

    Computational mechanisms of curiosity and goal-directed exploration

    Philipp Schwartenbeck, Johannes Passecker ... Karl J Friston
    Distinct computational levels of uncertainty compel agents to gain information about hidden states in the world (‘active inference’) or optimise their ‘world model’ as such (‘active learning’).

    Genetic association and causal inference converge on hyperglycaemia as a modifiable factor to improve lung function

    William R Reay, Sahar I El Shair ... Murray J Cairns
    Genetic data revealed existing drugs that could be repurposed to improve lung function, with evidence that compounds which control blood glucose could be particularly useful for respiratory impairment.

    A Bayesian model of context-sensitive value attribution

    Francesco Rigoli, Karl J Friston ... Raymond J Dolan
    The dependence of incentive value attribution on the anticipation of rewards within a given context is explained via a normative Bayesian account of how rewards map to incentive values.

    Relating pathogenic loss-of-function mutations in humans to their evolutionary fitness costs

    Ipsita Agarwal, Zachary L Fuller ... Molly Przeworski
    Loss-of-function mutations in human genes are an important class of disease causing variation, and estimates of their effects on evolutionary fitness can be used to evaluate their pathogenicity.

    Sepsis leads to lasting changes in phenotype and function of memory CD8 T cells

    Isaac J Jensen, Xiang Li ... Vladimir P Badovinac
    Sepsis leads to lasting changes in the composition of the pre-existing memory CD8 T cell compartment leading to altered localization, changes in their transcriptional landscape and chromatin accessibility, differential function, and reduced capacity to control infection.

    Characterization of sequence determinants of enhancer function using natural genetic variation

    Marty G Yang, Emi Ling ... Thomas Vierbuchen
    Large-scale, allele-resolved mapping of cis-regulatory function in F1-hybrid mice reveals sequence determinants that control transcription factor binding and enhancer activity in native chromatin context.

    Philosophy of Biology: The meanings of 'function' in biology and the problematic case of de novo gene emergence

    Diane Marie Keeling, Patricia Garza ... Anne-Ruxandra Carvunis
    A lexicon to help scientists and philosophers discuss the meaning of function in molecular biology more clearly is proposed.

    Gain-of-function variants in the ion channel gene TRPM3 underlie a spectrum of neurodevelopmental disorders

    Lydie Burglen, Evelien Van Hoeymissen ... Joris Vriens
    Newly identified gain-of-function variants indicate TRPM3 as the cause of a spectrum of autosomal dominant neurodevelopmental disorders with frequent cerebellar involvement in humans.

    Coevolution-based inference of amino acid interactions underlying protein function

    Victor H Salinas, Rama Ranganathan
    A deep mutational coupling study demonstrates the ability of sequence coevolution methods to reveal the pattern of amino acid interactions underlying protein function.
