How is haze formed?

Haze is formed when a cocktail of various gaseous pollutants is oxidized and forms particulate matter diffusing sunlight. This process is mainly mediated by hydroxyl radicals (OH), and researchers have now discovered a new route to their formation. This newly discovered radical-building mechanism could also offer new perspectives for air purification and the energy industry, …

Earthworms are a welcome sight for gardeners and farmers because the wriggling invertebrates recycle nutrients from soil, making them more accessible to plants. As worms burrow, they consume almost everything in their path, including microscopic plastic pollution. Now, researchers have observed that earthworms actually prefer soil with some types of microplastics but digest the polymers …
