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, ...

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 ...

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 ...

Lithium sulfur batteries are often touted as the next major chemistry for electric vehicle applications, if only their cycle life wasn’t so short. But that might be changing soon, as a group of ...

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 ...
