The processes that haul gold up to the surface from deep within Earth's mantle rely on the sulfur that bubbles beneath active volcanoes. Two new papers have agreed that some forms of sulfur form ...

Sedimentary rocks created more than 2.4 billion years ago sometimes have an unusual sulfur isotope composition thought to be caused by the action of ultra violet light on volcanically produced sulfur ...

A research team led by Prof. SHEN Yan'an from the University of Science and Technology of China (USTC) has made significant progress in studying the sources and formation mechanisms of haze. Through ...

Instead of sulfur dioxide, the University of Washington researchers are using specially designed nozzles to spray misted seawater containing tiny particles of sea salt over the deck of the Hornet.

Geoengineering experiments like cloud brightening and sulfur dioxide injection are being explored to cool the planet. These technologies raise concerns about unintended consequences and could ...
