    Collider bias and the apparent protective effect of glucose-6-phosphate dehydrogenase deficiency on cerebral malaria

    James A Watson et al.
    Selection bias, also known as collider bias, likely explains the apparent protective effect of G6PD deficiency against cerebral falciparum malaria.

    Non-crossover gene conversions show strong GC bias and unexpected clustering in humans

    Amy L Williams et al.
    In humans, non-crossover gene conversion events transmit GC alleles in 68% of cases and exhibit a complex pattern of multiple disconnected tracts clustered within 20–30 kilobase intervals.

    Meta-analysis challenges a textbook example of status signalling and demonstrates publication bias

    Alfredo Sánchez-Tójar et al.
    Meta-analysis takes down a textbook example in behavioural and evolutionary ecology, and demonstrates the existence of biases in the current scientific publishing culture.

    Lying in a 3T MRI scanner induces neglect-like spatial attention bias

    Axel Lindner et al.
    Exposing subjects to the magnetic field of an MRI scanner stimulates the vestibular organ and thereby induces a horizontal bias of spatial orienting and exploration similar to that seen in stroke patients with spatial neglect.

    Asymmetric random walks reveal that the chemotaxis network modulates flagellar rotational bias in Helicobacter pylori

    Jyot D Antani et al.
    Asymmetric forward and backward swimming speeds reveal that the rotational bias, and not reversal frequencies, is an appropriate measure of chemotaxis signaling in Helicobacter pylori..

    A Tgfbr1/Snai1-dependent developmental module at the core of vertebrate axial elongation

    André Dias et al.
    During vertebrate axial extension, the tail bud originates from the activation of a developmental module in a subset of axial progenitors, concurrent but different to gastrulation.

    Research: Bias in the reporting of sex and age in biomedical research on mouse models

    Oscar Flórez-Vargas et al.
    A text-mining study suggests that about half of the papers reporting the results of experiments on mice do not report the sex and age of the mice.

    Standardized mean differences cause funnel plot distortion in publication bias assessments

    Peter-Paul Zwetsloot et al.
    Funnel plots of the Standardized Mean Difference versus the standard error are prone to distortion, leading to false-positive tests for funnel plot asymmetry, and therefore using the Normalised Mean Difference, or a sample size-based precision estimate, are more reliable alternatives.

    Pupil-linked phasic arousal predicts a reduction of choice bias across species and decision domains

    Jan Willem de Gee et al.
    Across species and domains of decision-making, pupil-linked phasic arousal predicts suppression biases in the accumulation of evidence leading up to a choice.

    How prior preferences determine decision-making frames and biases in the human brain

    Alizée Lopez-Persem et al.
    Model-based analyses of choice behavior and fMRI activity revealed that prior preferences generate default policies, which frame the decision value signal encoded in the vmPFC, and shift vmPFC pre-choice activity so as to induce a decision bias toward default options.
