Floating-electron catalyst withstands week in air while making ammonia under milder conditions
Researchers at Science Tokyo created BaSiN2:O, a catalyst material that maintains stability in air for a week while synthesizing ammonia under milder conditions than conventional methods. The material achieves this through oxygen-doped barium silicon nitride that forms a stable surface layer of freely floating electrons.

Scientists calculated that Venus's clouds' unidentified dark ultraviolet material absorbs light far more strongly than previously thought. This finding narrows possibilities for determining whether the mysterious substance is organic, inorganic, or something unexpected.
Scientists find water was fueling volcanoes 3 billion years ago
Water-rich crustal material sank into Earth's mantle more than three billion years ago through a process called "dripduction," fueling volcanic eruptions. Ancient rocks from Western Australia provided evidence that this water-delivery mechanism operated long before modern plate tectonics fully developed.
Scientists discover a hidden switch that shuts down inflammation
Scientists discovered a natural braking system that switches off inflammation and prevents harmful immune cell buildup. Boosting this pathway in people reduced inflammation-related immune changes and accelerated pain relief.
