Lanthanide elements are important for clean energy and other applications. To use them, industry must separate mixed lanthanide sources into individual elements using costly, time-consuming, and waste-generating procedures. An efficient new method can be tailored to select specific lanthanides. The technique combines two substances that do not mix and that prefer different types of lanthanides. The process would allow for smaller equipment, less use of chemicals, and less waste production.

Most Americans report having personally experienced the effects of extreme weather, according to new survey data. An analysis finds that a reported exposure to extreme weather is associated with support for a half-dozen pro-environmental government policies that are intended to mitigate the effects of climate change and are contained in the Inflation Reduction Act of 2022.

California, a state known for its aggressive greenhouse gas reduction policies, is ironically the nation's greatest emitter of one: sulfuryl fluoride. As much as 17% of global emissions of this gas, a common pesticide for treating termites and other wood-infesting insects, stem from the United States. The majority of those emissions trace back to just a few counties in California, finds a new study.

Researchers show that using magnetic fields can boost electrocatalysis for sustainable fuel production by enhancing the movement of the reactants, which improves the efficiency of energy-related reactions.

To better understand COVID-19's spread during the pandemic, public health officials expanded wastewater surveillance. These efforts track SARS-CoV-2 levels and health risks among most people, but they miss people who live without shelter, a population particularly vulnerable to severe infection. To fill this information gap, researchers tested flood-control waterways near unsheltered encampments, finding similar transmission patterns as in the broader community and identifying previously unseen viral mutations.

Choosing paint for your home brings a lot of options: What kind of paint, what type of finish and what color? Water-based paints have emerged as 'greener' and less smelly than solvent-based options. And they are often advertised as containing little-to-no volatile organic compounds (VOCs). But, according to new research, some of these paints do contain compounds that are considered VOCs, along with other chemicals of emerging concern.

Until now, groundwater -- a critical water resource around the globe, especially in dry regions -- has been largely unstudied in its importance and role in sustaining ecosystems. New groundbreaking research examines the relationship between groundwater and ecosystems across California.

A new study finds that universities scoring strongly on measures of sustainability are associated with innovation and economic growth in their surrounding communities. However, the study did not find similar connections between university sustainability performance and environmental sustainability in their home communities.

Researchers describe zircons from the Andes mountains of Patagonia. Although the zircons formed when tectonic plates were colliding, they have a chemical signature associated with when the plates were moving apart. The researchers think that the unexpected signature could be explained by the mechanics of underlying tectonic plates that hasn't yet been described in other models.

There is room for just one small bottle in the world's first refrigerator that is cooled with artificial muscles made of nitinol, a nickel-titanium alloy. But the mini-prototype is groundbreaking: it shows that elastocalorics is becoming a viable solution for practical applications. This climate-friendly cooling and heating technology is far more energy-efficient and sustainable than current methods.

Windows welcome light into interior spaces, but they also bring in unwanted heat. A new window coating blocks heat-generating ultraviolet and infrared light and lets through visible light, regardless of the sun's angle. The coating can be incorporated onto existing windows or automobiles and can reduce air-conditioning cooling costs by more than one-third in hot climates.

An international team of scientists published a study emphasizing the urgent need to align political will, economic resources, and societal values to ensure a more sustainable and equitable world. The review summarizes the grave threats facing the planet but rejects a 'doom and gloom' philosophy. They advocate a global cultural shift that elevates kinship with nature and communal well-being, underpinned by the recognition of Earth's finite resources and the interconnectedness of its inhabitants.

Scrub mints are among the most endangered plants you've probably never heard of. More than half of the 24 species currently known to exist are considered threatened or endangered at the state or federal level. In a new study, researchers show there are likely more scrub mint species waiting to be scientifically described. And at least one species has been left without federal protection because of a technicality.
