PFAS are among the most insidious pollutants, thanks to their ubiquity, their long life and their growing list of linked health concerns. But now researchers at the University of California, Riverside ...

NASA confirms hydrogen detection from 3I/Atlas using MAVEN, providing new clues about the interstellar comet’s makeup.

Astronomers have discovered something unexpected in the birthplaces of young stars: ultraviolet (UV) radiation where it ...

Researchers used the MIRI instrument onboard the James Webb Space Telescope (JWST) to identify the presence of ultraviolet ...

Light to fuel: clean hydrogen production. Improved understanding of the light-driven production of hydrogen holds the promise not just to make the reaction more efficient in producing a fuel, but also ...

Even the faintest trace of hydrogen gas can spell trouble. In a chemical plant, it may auger a catastrophic industrial explosion; on a patient’s breath, it can signal various gastrointestinal problems ...

Hydrogen sulfide famously stinks like rotten eggs, and contributes that eye-watering, low-hanging punch to the bouquet of the very worst farts. It's also toxic, corrosive, flammable and produced in ...

Star formation should be a relatively straightforward process. Dense clouds of molecular hydrogen collapse under gravity, fragmenting into cores that grow into protostars. These infant stars are cold, ...

Ultraviolet light blasting the atmosphere of giant exoplanet WASP-39b is producing a toxic gas called sulfur dioxide. Photochemistry is a key process in Earth’s atmosphere too, and on most of the ...
