A new study published in National Science Review examines China's trends in primary particulate matter (PM) emissions from 1960 to 2019, revealing significant transformations in PM size fractions and carbonaceous compositions. Despite an overall decline in emissions, finer particles like PM2.5 and carbonaceous fractions (e.g., black carbon and organic carbon) have increased. These findings underscore the critical role of technological advancements and policy-driven measures in shaping the trajectory of air quality improvements.
Cardiovascular disease (CVD) is the leading cause of morbidity and mortality globally, posing a particularly significant threat to people with HIV (PWH). To address this, CVD prevention plans rely on prediction models like atherosclerotic cardiovascular disease (ASCVD) risk scores to estimate the risk of heart disease.
However, previous studies have called into question whether these commonly used prediction models perform well among people with HIV, and there remains a gap in understanding of what these scores mean for PWH in low- and middle-income countries (LMICs).
Neuroscientists at Washington University in St. Louis have set up computer frameworks that can help model individual brain dynamics.
Researchers at Baylor College of Medicine and collaborating institutions have improved our understanding of how rotavirus, the most common cause of acute gastroenteritis in children, makes people sick. The study published in Science Advances is among the first to show that the rotavirus protein NSP4 is both necessary and sufficient for multiple aspects of rotavirus infection by disrupting calcium signaling not only within infected cells but also in nearby uninfected cells. These disruptions in calcium signaling affect rotavirus disease severity, providing new insights into how NSP4’s function influences rotavirus virulence. The findings suggest that manipulating NSP4 could lead to new strategies to prevent or treat rotavirus infections.
