A European study found that 90% of so-called eco-friendly paper straws contain “forever chemicals,” compounds that barely break down and can accumulate in our bodies, leading to health problems. The findings are consistent with previous US studies.
-
Fog nets are a literal lifesaver in arid regions with regular fog – but unfortunately they can also capture airborne pollution. Scientists at ETH Zurich have now developed fog nets that can use sunlight to break down hazardous molecules.
-
Estrogen can harm aquatic plants and animals when passed into waterways via human and agricultural waste streams. Researchers have now developed a new way of removing the hormone from water, however, using what's known as "smart rust."
-
It’s well established that any air pollution is hazardous, with it claiming some 6.5 million lives around the world each year. But one type of emission is being increasingly linked to age-related dementia, and it’s also surging due to wildfires.
-
While “don’t mess with Texas” may have originated as a littering campaign catchphrase, scientists from the southern state have aimed that mantra at waterborne bacteria, creating a drinking cup that kills pathogens that cross its electric field.
-
Traffic is among the biggest sources of air pollution, but what if the very roads they drive on could help clear the air? Engineers in Korea have now demonstrated that photocatalytic concrete can help reduce pollution in tunnels.
-
Researchers have demonstrated how effective plants are at ridding the air in your home, school, or workplace of toxic, potentially cancer-causing pollutants, providing a sustainable, low-cost way of ensuring that the air you breathe is cleaner.
-
In recent years, pomegranate-derived compounds have been shown to slow cellular aging, protect unborn babies' brains, and serve as additives in better automotive materials. Now, they've also been used to remove pharmaceuticals from wastewater.
-
The Ocean Cleanup has announced a second Indonesian river trash removal mission. The solar-powered Interceptor 020 will prevent around 1,000 tons of plastic waste flowing into the Java Sea each year from the Cisadane River.
-
Removing heavy metal pollutants from water could soon be easier than ever, thanks to an experimental new sponge. With just one treatment, the device brought contaminated water down to safely drinkable levels.
-
New research out of China has unveiled a concerning link between air pollution exposure and heart rhythm disturbances, further demonstrating the dangers of unclean air and the urgent need for global efforts to improve air quality.
-
Scientists at the University of Georgia have created a "superfoam" with two very valuable potential applications. It could be used not only to clean up oil spills, but also to keep infections from occurring at medical implant sites.
