In the oldest, most pristine rocks, oxygen -- the most abundant element in the Earth's crust -- follows a strange, anomalous pattern that must result from a different chemical process than the well-understood reactions that form minerals containing oxygen on Earth.
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.
An international research team working with National Institute of Standards and Technology (NIST) scientists at the Hollings Marine Laboratory (HML) in Charleston, SC, has suggested for the first time that mercury cycling in the flora and fauna of the Arctic may be linked to the amount of ice cover present.
Chemists at UC San Diego have uncovered a new chemical reaction on tiny particulates in the atmosphere that could allow scientists to gain a glimpse from ancient rocks of what the atmospheres of the Earth and Mars were like hundreds of millions years ago.
A study by University of Michigan researchers offers new insight into what happens to mercury deposited onto Arctic snow from the atmosphere.
University of Michigan researchers have developed a new tool that uses natural "fingerprints" in coal to track down sources of mercury polluting the environment.
Results critical to interpretation of GENESIS spacecraft samples of the sun.
From chemical fingerprints preserved in primitive meteorites, scientists at UCSD have determined that the collapsing gas cloud that eventually became our sun was glowing brightly during the formation of the first material in the solar system more than 4.5 billion years ago.
WASHINGTON (Reuters) - Our Sun was already shining brightly more than 4.5 billion years ago, as dust and gas was swirling into what would become the planets of the solar system, U.S. researchers reported on Thursday.
- Having no light.
- Of or relating to the region of a body of water that is not reached by sunlight and in which photosynthesis is unable to occur.
