Training-induced perceptual gain in the discrimination between odor enantiomers is nostril-specific and structure-based, indicating that early olfactory processing of the chemical features of unirhinal input remains plastic in human adults.
Although the ID NOW platform is less sensitive than RT–PCR for identification of SARS-CoV-2 infection, it provides high positive and negative predictive values in low-prevalence populations.
The function of human airway macrophages can be therapeutically manipulated by targeting cellular metabolism to support immunity in the lung, aiding the design of innovative strategies in respiratory medicine.
A combination of window-of-sensitivity, genetic, and in vitro findings illuminate mechanisms of gene–environment interaction in a multifactorial model of a common birth defect.

Oxytocin was found to significantly improve non-social decision making in a healthy sample, suggesting a domain-general function of the hormone, in contrast to its previously hypothesized social domain specificity.
A genome-organizing protein that is present only in the olfactory system of mice has been found to orchestrate changes in the relative numbers of different odor-sensing neurons on the basis of how active these neurons are.
Male and female mice respond differently to the same pheromone signals, and the representation of these sensory stimuli by neurons in the medial amygdala correlates precisely with the differences in behavior.
A randomized placebo-controlled trial with behavioral, neuroimaging, and physiological measures reveals that oxytocin treatment facilitates pleasure and brain reward responses only to gentle stroking social touch by increasing peripheral blood concentrations.

In the dioecious plant genus Leucadendron, shifts to sex-biased gene expression occurred predominantly in genes with ancestrally high rates of expression evolution, and were not correlated with morphology.

Genome-wide association studies have established staphylococcal pyomyositis as a disease whose pathogenesis depends critically on expression of a single toxin, Panton–Valentine leukocidin.
