Reusable sponge-like (foam) sorbent materials for cleaning up oil spills may soon become available, as a result of promising research from multiple groups. Oil spills damage ecosystems and habitats, harm and kill wildlife and plants, contaminate…

Plastic shopping bags are convenient to use because they are lightweight and inexpensive, and yet they are also a major source of plastic pollution. People worldwide use an estimated 500 billion to 1 trillion single-use plastic bags each year.…

More apples are consumed worldwide than any other temperate-zone tree fruit. Apples are eaten fresh, processed into jellies and preserves, cooked in pies and pastries, and made into sauces. Therefore, the cultivation of the trees (genus Malus) that…

Seawater desalination involves removing salts and minerals from water and discharging a higher-concentration solution, or brine, to the sea. The brine effluent may affect the water quality (for example, salinity) and organisms—particularly the…

Those who fear contracting a water-borne illness caused by pollution at the shore or ingesting a killer amoeba (Naegleria fowleri) at a freshwater lake might instead opt to visit a swimming pool. After all, most pool water is hygienically treated.…

Researchers have developed polymeric materials that are able to kill multidrug-resistant bacteria without inducing drug resistance or toxic side effects, according to a report in Nature Communications (March 2018). The polymers, known as…

In an application of green chemistry, researchers reported in the journal Biomaterials (April 2018) the caffeine-catalyzed synthesis of a new class of polymer gels for drug delivery and other biomedical applications. These caffeine-catalyzed gels…

Neonicotinoid insecticides are the most used insecticide worldwide and have been linked to the decline of pollinator insects. In 2018, the European Union banned the outdoor use of three neonicotinoid insecticides: clothianidin, imidacloprid, and…

Handheld electronic devices with plastic casings, such as cell phones, may be exposing users to toxic organophosphate ester (OPE) flame retardants that leach out of these products. Researchers from the University of Toronto reported in Environment…

In the journal Science (September 2018), researchers reported a method for making a coating that reflects sunlight and radiates heat. The coating can be used to cool buildings and reduce air-conditioning use, keeping surfaces painted with the…
