3+ hour, 34+ min ago (696+ words) Researchers in Finland have shown that simple molecules related to everyday oils, plus visible light, can dissolve silver without relying on harsh chemicals." The same chemistry can pull silver from waste and then return it as solid metal ready for reuse. Today, only around one fifth of global silver supply comes from recycling. This is despite the fact that demand keeps rising in electronics and solar panels." Scientists call this urban mining, recovering metals from discarded products instead of digging new ore. The new chemistry helps make that recovery even more practical. Work on the new recycling route was led by postdoctoral researcher An'e Zupanc at the University of Helsinki. His research focuses on using simple organic molecules as tools for cleaner metal recovery. For more than a century, many mines have used cyanide leaching to pull metals from crushed…...

18+ hour, 51+ min ago (667+ words) A new study has found that many everyday chemicals can harm the good bacteria living in your gut. These bacteria are important for keeping your body healthy, but researchers have discovered that 168 different human-made substances can stop these microbes from growing properly. Many of these chemicals are found in food, drinking water, and the environment, but until now, they were not believed to affect gut bacteria. The study was done by scientists at the University of Cambridge. They tested over 1,000 different chemicals to see how they affected 22 common types of gut bacteria in a lab setting. These chemicals included pesticides like herbicides and insecticides used on crops, and industrial chemicals found in plastics and flame retardants. Our gut is home to thousands of different kinds of bacteria that help with digestion, the immune system, mental health, and more. If something…...

18+ hour, 53+ min ago (428+ words) A rocky exoplanet outside the Earth's solar system may have an atmosphere, according to new evidence gathered by NASA researchers. The exoplanet's low density has surprised and baffled scientists, NASA said. It may have an unusual composition from planets in Earth's solar system. It could also be surrounded by a thick atmosphere, which would not be expected on an exoplanet with these features. But the James Webb Space Telescope helped scientists gather data that showed that unlikely scenario might be the case. Researchers used the telescope's Near-Infrared Spectrograph to measure the exoplanet's dayside temperature. If the exoplanet has no atmosphere, scientists estimated its dayside temperature would be about 4,900 degrees Fahrenheit. But the spectrograph found TOI-561b's temperature closer to 3,200 degrees Fahrenheit, far cooler than expected. Just determining the temperature of the exoplanet doesn't confirm if there is an atmosphere there,…...

19+ hour, 28+ min ago (185+ words) Dr. Yu Lei, chair of the UAH Department of Chemical & Materials Engineering. "PFAS are often called forever chemicals because their carbon'fluorine bonds are among the strongest in chemistry, making them very hard to break down," the researcher notes. "They can move from one place to another, for example, from water into soil or sludge, instead of being truly destroyed. That persistence makes them difficult to manage. The work entails a combination of both laboratory research and computational modeling with seven universities collaborating closely across their respective areas of expertise. "Beyond the research, the project also emphasizes workforce development ' training graduate students, postdocs and junior faculty through collaborative research and exchanges across the three states. It's not just about addressing the PFAS challenge, but also about building the next generation of scientists and engineers ready to take on future environmental problems....

20+ hour, 42+ min ago (532+ words) By removing electricity from the equation, researchers found lithium behaves very differently inside charged membranes. A simple laboratory experiment at the University of Michigan has revealed an unexpected way to extract lithium from brines long dismissed as uneconomical. The discovery could unlock vast lithium resources trapped in magnesium-rich waters, offering a more sustainable route to meet rising demand from batteries, electric vehicles, and renewable energy systems. Lithium supply already faces mounting pressure. Mining from hard rock remains costly and environmentally damaging, while conventional brine extraction depends on vast evaporation ponds that consume land and water. Although brines hold more than half of the world's lithium, most remain unused because high magnesium levels complicate extraction. "In some natural brines, the conventional approach isn't economical, so people aren't utilizing the resource," said Jovan Kamcev, an associate professor of chemical engineering and the…...
