New research highlights the scale and regional disparities in inefficient investment in expensive and energy-intensive imaging equipment, such as computed tomography (CT) and magnetic resonance imaging (MRI) machines, in Japan. The study discovered that more than 80% of prefectures operated CT and MRI scanners inefficiently in 2020, leading to substantial
Air pollution
Researchers at Nankai University have developed an Interpretable Machine Learning (IMLS) and source apportionment (IMSA) framework to understand the interaction between fine particulate matter (PM2.5) control and carbon reduction. The study found that industrial emissions (11%), vehicle exhaust (13%), and coal combustion (19%) are major shared sources of pollutants
Air pollution
A new study published in the New Journal of Chemistry has found a practical and effective way to reduce air pollution in the coating industry by promoting oxygen activation and weakening the Co-O bond strength on the cobalt oxide surface. The research, conducted by scientists at the South China University

A nationwide study in Taiwan has uncovered a significant association between prenatal air pollution exposure and the risk of childhood leukemia. The research, conducted by scientists from Taichung Veterans General Hospital, analyzed data from over 3900 children, including 965 leukemia cases, and found that exposure to certain air pollutants during
Air pollution
Research conducted at Tianjin University has shed light on the complex chemical reaction between ammonia and hydrocarbon molecules, which influences the formation of soot precursors like benzene, complicating the study of soot in ammonia-diesel fuels. The study found that as the ammonia energy ratio (AER) increases, the average particle size
Air pollution
Researchers from Mapua University in Manila, Philippines, have identified air pollution as a serious health risk, with 99% of the global population breathing air with pollutant levels exceeding safe guidelines, according to the World Health Organization (WHO). Investigating six common household pollutants, the study found that volatile organic compounds (VOCs)
Air pollution
Recent research has highlighted the significant risks posed by diesel exhaust particles (DEP) to public health, particularly with regards to bone metabolism. A study conducted by the Indian Institute of Technology (IIT) Madras has investigated the osteogenic and bone toxic effects of DEP on both in vitro pre-osteoblast models and
Air pollution
Despite ongoing efforts to reduce emissions, the largest urban areas in the United States continue to exceed national air quality standards for ozone, according to a recent study. Researchers from the NOAA Chemical Sciences Laboratory conducted a study to investigate non-linear ozone photochemistry in New York City, Chicago, and Los
