The amount of environmental exposure to polycyclic aromatic hydrocarbons, or PAH for short, is strongly linked to a person's risk of developing rheumatoid arthritis, suggests research published in the ...

Worse, these contaminated particles pose a double risk, researchers said – first when they are airborne, and again when they ...

Polycyclic aromatic compounds, characterised by fused aromatic rings, underpin advances in organic electronics, photonics and catalysis. Synthetic approaches broadly divide into bottom-up ...

Polycyclic aromatic hydrocarbons (PAHs) are typical organic compounds found in cigarette smoke and vehicle exhaust. In addition, PAHs are produced from incomplete combustion of organic material and ...

Whenever an organic matter is burned, such as in a wildfire, a power plant, a car's exhaust, or in daily cooking, the combustion releases polycyclic aromatic hydrocarbons (PAHs) - a class of ...

Analysis of organic compounds -- called polycyclic aromatic hydrocarbons (PAHs) -- extracted from the Ryugu asteroid and Murchison meteorite has found that certain PAHs likely formed in the cold areas ...

When fire tore through Los Angeles County in January 2025, westerly winds blew most of the smoke and ash over the Pacific, ...

Making children laugh can build deep emotional connections and soothe their nervous systems, making them more resilient and open to new ideas, says a leading child development expert. Dr. Jacqueline ...

A Hong Kong University of Science and Technology (HKUST) research team has developed a catalytic enantioselective type II [5 + 2] cycloaddition method to address the challenges of synthesizing chiral ...
