Ancient sediments that once resided on a lake bed and the ocean floor show sulfur isotope ratios unlike those found in other samples from the same time, calling into question accepted ideas about when ...

Researchers from the Max Planck Institute for Extraterrestrial Physics in Germany and the Centro de Astrobiología, part of ...

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 ...

The organism, an early-evolving bacterium named Hydrogenobacter, thrives in the hydrothermal spring environments of Yellowstone National Park, which are rich in sulfur but have very low dissolved ...

A breakthrough strategy using sulfur-rich precursors to engineer porous heterojunctions has overcome critical bottlenecks in water-splitting catalysts, paving the way for green hydrogen production.

PREVIOUSLY 1, we have shown that minute traces of oxygen lead to an apparent increase in the rate of formation of hydrogen sulphide from its elements, as judged by the iodine titre of the resulting ...
