Chemists have discovered a way to use light and oxygen to upcycle polystyrene — a type of plastic found in many common items — into benzoic acid, a product stocked in undergraduate and high school chemistry labs and also used in fragrances, food preservatives, and other ubiquitous products.
Around 180,000 avoidable deaths over 14 years in fast-growing tropical cities were caused by a rapid rise in emerging air pollution, a study has revealed.
Researchers call for cities to better manage and treat urban runoff to protect sources of drinking water and reduce the impacts on aquatic ecosystems.
New research highlights a technique known as Wastewater-based Epidemiology (WBE), in which samples of municipal wastewater can be used as a diagnostic tool to explore a surprisingly broad range of community-wide health indices.
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 …
Analysis presents a first-of-its-kind framework to design the most efficient mix of urban buildings along with integrated systems to supply power and water services. The approach could significantly reduce costs and pollution compared to traditional systems.
Researchers using an ‘acoustic camera’ discover how individual songs in an amphibian chorus influence mating in wood frogs.
Interactions between microbes and other organisms are mediated by a plethora of small molecules, also called natural products. Researchers have now performed a systematic analysis of biosynthetic ‘dark matter’ and biological functions, thus creating a solid basis for future discovery and refinement of natural products.
Every ship channel has to be dredged. With high costs involved, a dredging project’s managers have to be on the money in their timing and logistics choices. A new algorithm presents decision-makers with accurate context, comparisons and boots-on-the ground observations.
Scientists explore microbial communities flourishing in leachate, a liquid percolating through solid waste in a landfill. They find that the composition and behavior of specific microbes found in arid landfills, like those in Arizona, are distinct from similar communities in more subtropical or temperate climates. Microbial composition also differs depending on the age of the …
