Greed personality trait is associated with behavioral loss aversion via the mediation of the neural loss aversion signal in the medial orbitofrontal cortex.

Prompt contact tracing (testing at the beginning instead of at the end of isolation period) of individuals with COVID-19 in the community reduces delays in contact tracing, increases identification of source of infection, and reduces transmission rates in educational settings.

Two genome sequencing studies show a consistent association between blood mitochondrial DNA copy number (mtDNAcn) and personality traits and provide support for the hypothesis that mtDNAcn may be a biomarker that connects certain personality characteristics with mortality.

Epigenetic regulations in the smoking- and blood pressure-related pathways to the future risk of coronary heart disease may reveal novel pathways or therapeutic targets.

More parent-reported infections in the first year of life were associated with metabolic differences linked with cardiovascular and metabolic disease in adulthood, with observational evidence for inflammation partly mediating this relationship.

Analysis of proteomic data identified protein biomarkers of aging, mortality and aging-related diseases, supporting their use to monitor aging trajectories and identify individuals at higher risk of disease.

What can authors and reviewers do to keep common statistical mistakes out of the literature?

Measures of sleep features such as spindles and slow waves differentiate between young people with 22q11.2 microdeletion syndrome and healthy controls, and may mediate the relationship between this genotype and psychiatric symptoms.

Apparent age-related differences in learning are best accounted for by rapid decay of information in working memory, which is associated with levels of prefrontal glutamate.

Socio-economic hierarchies may be bad for health, even among people living in a relatively traditional, small-scale society in the Bolivian Amazon.
