    Environmental response in gene expression and DNA methylation reveals factors influencing the adaptive potential of Arabidopsis lyrata

    Tuomas Hämälä, Weixuan Ning ... Outi Savolainen
    Environmentally responsive genes evolve under strong selective constraint in Arabidopsis lyrata.

    Mechanisms of distributed working memory in a large-scale network of macaque neocortex

    Jorge F Mejías, Xiao-Jing Wang
    An anatomically constrained computational model of the macaque cortical network demonstrates the emergence of large-scale distributed patterns of mnemonic activity sustained by long-range cortico-cortical interactions.

    Evolution of C4 photosynthesis predicted by constraint-based modelling

    Mary-Ann Blätke, Andrea Bräutigam
    Constraint-based modelling predicts C4 photosynthesis evolves under resource limitation from an ancestral ground state of C3 photosynthesis and attributes divergent metabolic routes in extant C4 subtypes to light.

    Decreased recent adaptation at human mendelian disease genes as a possible consequence of interference between advantageous and deleterious variants

    Chenlu Di, Jesus Murga Moreno ... David Enard
    Harmful genetic variants at mendelian disease genes slow down adaptation, by interfering with the spread of adaptive variants in a population.

    A two-lane mechanism for selective biological ammonium transport

    Gordon Williamson, Giulia Tamburrino ... Arnaud Javelle
    A new cellular transport mechanism splits the substrate and separately translocates its fragments to achieve selectivity.

    Stability-mediated epistasis constrains the evolution of an influenza protein

    Lizhi Ian Gong, Marc A Suchard, Jesse D Bloom
    Some of the mutations that occur during influenza evolution can only be tolerated in conjunction with other mutations that increase the stability of a viral protein.

    Human genetic analyses of organelles highlight the nucleus in age-related trait heritability

    Rahul Gupta, Konrad J Karczewski ... Vamsi K Mootha
    Although cellular organelles show a functional deterioration in aging, genetic loci associated with common age-associated disease instead nominate nuclear transcription factors across several age-related diseases.

    Contribution of correlated noise and selective decoding to choice probability measurements in extrastriate visual cortex

    Yong Gu, Dora E Angelaki, Gregory C DeAngelis
    Addressing the controversy regarding the interpretation of choice probabilities demonstrates that both readout strategy and noise correlations contribute to the link between neural activity and perceptual decisions.
    1. Neuroscience

    Current and future goals are represented in opposite patterns in object-selective cortex

    Anouk Mariette van Loon, Katya Olmos-Solis ... Christian NL Olivers
    Multivoxel pattern of fMRI data reveals how the brain distinguishes between relevant and irrelevant representations as representations adapt to the order in which they are required in multiple task sequences.

    Thousands of novel translated open reading frames in humans inferred by ribosome footprint profiling

    Anil Raj, Sidney H Wang ... Jonathan K Pritchard
    Over 7,000 novel translated sequences have been identified from human cells, including several hundred in annotated noncoding RNA, pseudogenes and de novo assembled transcripts.
