Media Behaviors Considered by Older Adults During Health Emergencies: A Cross-National Study
PurposeTo identify the predictors of the technology-assisted behaviors older adults would consider implementing once encountered with a health concern and seeking help. To understand this phenomenon, the study tapped into the technology familiarity approach and the media richness theory.MethodsData were obtained from the 2020 wave of the Ageing, Communication, Technologies (ACT) survey and analyzed using logistic regression models. The sample included 3,926 internet users 63-97 years old from...
Inflammaging and neurovascular unit dysfunction in cognitive ageing: mechanisms, biomarkers, and therapeutic opportunities
Age-related cognitive decline is increasingly recognised as arising from interacting immune and neurovascular vulnerabilities rather than from isolated insults. In this Review, we synthesise current human and mechanistic evidence within a convergence framework in which inflammaging and neurovascular unit (NVU) dysfunction are conceptualised as a feedback-coupled system. Persistent immune remodelling may promote endothelial activation, redox imbalance, pericyte-astrocyte support failure,...
Fossil skull flattening suggests ancient origins of infant helplessness
Homo erectus and H. floresiensis skulls both show defects similar to those modern human babies can develop after repeatedly resting on the same side
