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

    Andrew B Morgenthaler, Wallis R Kinney ... Shelley D Copley
    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.

    Normative evidence accumulation in unpredictable environments

    Christopher M Glaze, Joseph W Kable, Joshua I Gold
    Theoretically optimal dynamics for making decisions in unpredictable environments provide a broadly applicable framework for understanding choice behavior and underlying neural signals.

    Phosphorylation-mediated PTEN conformational closure and deactivation revealed with protein semisynthesis

    David Bolduc, Meghdad Rahdar ... Philip Cole
    C-terminal phosphorylation of the lipid phosphatase PTEN drives a reduction in membrane affinity and leads to a more compact conformation that involves a C2 domain-tail interaction.
  1. Point of view: Motivating participation in open science by examining researcher incentives

    Sarah E Ali-Khan, Liam W Harris, E Richard Gold
    A survey of researchers at the Montreal Neurological Institute and Hospital provides insights into the challenges and opportunities involved in adopting an open science policy across an entire patient-oriented academic institution.

    E. coli TraR allosterically regulates transcription initiation by altering RNA polymerase conformation

    James Chen, Saumya Gopalkrishnan ... Seth A Darst
    Cryo-electron microscopy structures, combined with biochemical experiments, show how the E. coli F element-encoded TraR protein regulates transcription initiation by altering RNA polymerase conformation and conformational heterogeneity.

    Heterogeneous absorption of antimicrobial peptide LL37 in Escherichia coli cells enhances population survivability

    Mehdi Snoussi, John Paul Talledo ... Sattar Taheri-Araghi
    A rapid absorption and retention of antimicrobial peptides by dead Escherichia coli cells can increase the survivability of the cell population in a "cooperative" fashion.

    Normative decision rules in changing environments

    Nicholas W Barendregt, Joshua I Gold ... Zachary P Kilpatrick
    In environments that fluctuate over the course of deliberation, optimal decision strategies display novel dynamics that can explain human response behaviors better than commonly used alternatives.
