Latest Sulfur cycle Stories
More than a mile beneath the ocean's surface, as dark clouds of mineral-rich water billow from seafloor hot springs called hydrothermal vents, unseen armies of viruses and bacteria wage war.
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.
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.
