Poor oral health may increase dementia risk through both biological and social pathways, as reported by researchers from Science Tokyo. Drawing on recent epidemiologic research, the team highlights how eating and speaking difficulties might act as overlooked social mechanisms that may amplify risk by contributing to social isolation. Moreover, in a longitudinal study, they also found that poor oral health is a strong predictor of weight loss in older adults.
Energy-efficient buildings are promising for sustainable development and energy consumption as per environmental, social, and economic criteria. Recently, researchers from Hanbat National University, and Kongju National University, Republic of Korea, have proposed polymer-dispersed liquid crystal-impregnated switchable thermochromic transparent woods that demonstrate excellent ultraviolet blocking performance for smart windows, promoting indoor illumination, privacy, and human health. The novel innovation can help pave the way for next-generation energy-efficient buildings.
Electric vehicles could become economically competitive in many African countries before 2040. Off-grid solar solutions make charging possible even in places with no or unreliable electrical grids. Major challenges remain in terms of financing, with high interest rates slowing down adoption, despite drops in cost of technology.
New study by LMU and the University of Konstanz shows broad public approval for the support of Ukraine to maintain its political and territorial sovereignty.
The possibility of high casualty numbers and the risk of nuclear escalation constrain support and carry more weight than economic costs.
Over 10,000 people in five major NATO countries, supporting Ukraine, were surveyed for the study.
As Australians return to work after the holidays, many will be reflecting on their health and wellbeing goals for the year ahead. New research reveals that while workplace factors like long hours, work-related stress and shift work do influence high-risk drinking, personal and social factors play an even bigger role.
