Geochemist Alexandra Phillips has sulfur on her mind. The yellow element is a vital macronutrient, and she’s trying to understand how it cycles through the environment. Specifically, she’s curious ...
The Sturtian Snowball Earth glaciation (717~660 million years ago) represents the most severe icehouse climate in Earth's history. Geological evidence indicates that, during this glaciation, ice ...
Nutrient cycles such as the carbon, nitrogen, phosphorous and sulfur cycles are critical processes that free up elements essential to life by recycling them through our water, air, and soil. Sulfur, ...
The hybrid sulfur cycle, integrating thermal and electrochemical processes, has emerged as a promising route for sustainable hydrogen production with minimal carbon emissions. At its core, the process ...
A study into Lake Superior has revealed a 3 billion-year-old secret about planet Earth. Researchers at the University of California, Santa Barbara, and University of Minnesota, Duluth, discovered a ...
Scientists have discovered that even among the sulfur-cycling microbes that are responsible for the 'rotten egg gas' smell in salt marsh air, diversity extends all the way to genomes and even to ...
Factors controlling global climate of the past and the future / E.T. Degens, H.K. Wong, and S. Kempe -- The biogeochemical nitrogen cycle / T. Rosswall -- Current problems related to the atmospheric ...
Recent advances in catalyst development have significantly improved the viability of the sulphur-iodine thermochemical cycle for sustainable hydrogen production. Key reactions within this cycle, ...
(Beyond Pesticide, August 27, 2020) The latest research finds that pesticides and fertilizers supersede fossil fuels as the greatest contributor of sulfur emissions in the environment, according to ...
