    Neural evidence accumulation persists after choice to inform metacognitive judgments

    Peter R Murphy, Ian H Robertson ... Redmond G O'Connell
    Error detection is contingent on the continuation of evidence accumulation after choice commitment, and the speed and accuracy of this process are modulated by high-level signals from medial frontal cortex.

    Neuronal representation of saccadic error in macaque posterior parietal cortex (PPC)

    Yang Zhou, Yining Liu ... Mingsha Zhang
    Neurons in the macaque posterior parietal cortex behave like an error detector that computes the saccadic error by comparing the intended and the actual saccade end-position signals.

    Visuomotor learning from postdictive motor error

    Jana Masselink, Markus Lappe
    Visual, motor, and forward model gains learn from a postdictive update of space to keep perception and saccadic motor function aligned.

    The mechanism of error induction by the antibiotic viomycin provides insight into the fidelity mechanism of translation

    Mikael Holm, Chandra Sekhar Mandava ... Suparna Sanyal
    The antibiotic viomycin induces errors during initial codon selection by the ribosome by locking the monitoring bases in their active conformation.

    High-throughput Plasmodium falciparum hrp2 and hrp3 gene deletion typing by digital PCR to monitor malaria rapid diagnostic test efficacy

    Claudia A Vera-Arias, Aurel Holzschuh ... Cristian Koepfli
    A novel high-throughput method for Plasmodium falciparum genotyping will enable malaria control programs to make informed decisions about the best tool to use for the diagnosis of malaria.

    Multiple inputs ensure yeast cell size homeostasis during cell cycle progression

    Cecilia Garmendia-Torres, Olivier Tassy ... Gilles Charvin
    Yeast cell size homeostasis is not controlled by a G1-specific mechanism alone but is likely to be an emergent property resulting from the integration of several mechanisms that coordinate cell and bud growth with division.

    Universal and taxon-specific trends in protein sequences as a function of age

    Jennifer E James, Sara M Willis ... Joanna Masel
    Ancient protein domains remain shaped by amino acid availability during early life, while young animal proteins are shaped by a need for high intrinsic structural disorder.

    Quorums enable optimal pooling of independent judgements in biological systems

    James AR Marshall, Ralf HJM Kurvers ... Max Wolf
    Consideration of signal detection theory shows how decision ecology relates to optimal collective decisions, helping explain the prevalence of quorum-sensing in even the simplest collective systems, such as bacterial communities.

    Nucleus accumbens dopamine tracks aversive stimulus duration and prediction but not value or prediction error

    Jessica N Goedhoop, Bastijn JG van den Boom ... Ingo Willuhn
    The extracellular concentration of dopamine in the nucleus accumbens core is progressively diminished by white noise, an underutilized, easy-to-titrate aversive stimulus, but is unaffected by white-noise intensity, context valence, and associated probabilistic contingencies.
    1. Neuroscience

    Competition between parallel sensorimotor learning systems

    Scott T Albert, Jihoon Jang ... Reza Shadmehr
    When a common error drives parallel implicit and explicit learning systems, increases in the explicit response will suppress implicit adaptation.
