A research team of biogeochemists at the University of California, Riverside has provided a new view on the relationship between the earliest accumulation of oxygen in the atmosphere, arguably the most important biological event in Earth history, and its relationship to the sulfur cycle.
For a long time now, scientists have been convinced that lava that has erupted from certain oceanic volcanoes contains material from the crust of early Earth, but decisive evidence has been elusive.
A new chemical process can transform waste sulfur into a lightweight plastic that may improve batteries for electric cars, reports a University of Arizona-led team. The new plastic has other potential uses, including optical uses.
A team of scientists has found particles from the upper atmosphere trapped in a deep pile of fluffy Antarctic snow that hold clear chemical traces of global meteorological events.
A research team from the University of California, San Diego is hoping to learn how our solar system evolved by studying the origins of different isotope ratios among the elements that make up today’s smorgasbord of planets, moons, comets, asteroids, and interplanetary ice and dust.
A systematic review published today in The Cochrane Library finds that in well-nourished adults current evidence does not support selenium for preventing heart disease.
Life on earth began in the oceans, but it would eventually spread to land and a new study suggests that land-dwelling bacteria could have covered large swaths of territory about 2.7 billion years ago, despite a thin ozone layer that would have offered little protection against the sun’s ultraviolet radiation.
The study of an oxygen-sensing bacterial regulatory protein by chemistry researchers at the University of Georgia has provided molecular insight into the oxygen sensing mechanism, which could ultimately lead to a better understanding of the ageing process and new treatments for human diseases such cancer, Parkinson's and Alzheimer's.
