The carotenoid-based colours of birds are a celebrated example of biological diversity and an important system for the study of evolution. Recently, a two-step mechanism, with the enzymes cytochrome P450 2J19 (CYP2J19) and 3-hydroxybutyrate dehydrogenase 1-like (BDH1L), was described for the biosynthesis of red ketocarotenoids from yellow dietary carotenoids in the retina and plumage of birds. A common assumption has been that all birds with ketocarotenoid-based plumage coloration used this...

With advancing age, neurovascular dysfunction manifests as impaired neurovascular coupling (NVC), microvascular rarefaction, and blood-brain barrier (BBB) disruption, contributing to vascular cognitive impairment (VCI). Our previous research established a causal link between vascular senescence induced cerebromicrovascular dysfunction and cognitive decline in accelerated aging models. The present study examines whether chronological aging promotes endothelial senescence, adversely affecting...

Chinese women face a tremendous threat of cervical cancer alongside low rates of human papillomavirus (HPV) vaccination. Online cancer information has become a driving force of HPV vaccination, but the underlying mechanism remains unclear. Drawing upon the three-stage model of health promotion, this study examines the relationships between online cancer information seeking and scanning and HPV vaccination intention among unvaccinated Chinese women. Specifically, the mediating roles of HPV...

Emotion recognition, the ability to interpret others' emotional expressions and infer mental states, is crucial for caregiver-child interactions. The ability to accurately recognize infant emotions may facilitate attuned and responsive caregiving. Across two studies, we validate a novel measure to assess the recognition of infants' emotions (Reading the Mind in Infant Eyes Test [RMIET]) and investigate how this ability relates to observed caregiving. Study 1 examined item-level performance in 55...
