Process doubles the size of PFAS molecules, making them easy to destroy‎

Ask a chemist to name the strongest single bond in organic chemistry, and they'll likely say carbon-fluorine. It's that bond, repeated dozens of times over, that gives per- and polyfluoroalkyl substances (PFAS) their nickname: forever chemicals. Manufacturers prize PFAS for the same reason regulators dread them. The bonds barely break down, which is exactly why the compounds are so good at repelling water, oil and heat in everything from semiconductor fabrication to nonstick cookware. This is also why PFAS persist in soil, water and living tissue long after serving their industrial purpose.

Natural gas drilling could raise salt levels, in turn boosting radium in water‎

Pennsylvania ranks second in U.S. natural gas production, accounting for about one-fifth of U.S. output in 2024, and has one of the most extensive histories of energy extraction in the country. A team of researchers from Penn State is trying to better understand the environmental impacts of these sites—specifically, whether fracking is increasing radium content in local drinking water.

NASA starshade would enable astronomers to directly image rocky exoworlds‎

A NASA-led team hopes to take a shortcut to direct imaging of extrasolar Earth-like planets. The idea is to use what they call a hybrid telescope composed of an orbital starshade coupled with the next-generation extremely large ground-based optical telescopes.
