Scientists have discovered that the electrical resistance of this material changes in an unusual way under very high magnetic fields—a finding that could help direct the search for materials that can perfectly conduct electricity at room temperature.
Sulfur isotopes can serve as tracers of atmospheric oxygen, and new data collected from the present-day atmosphere in China by an international team of researchers, led by the University of California San Diego, indicate remarkable similarity to the isotopic footprint found in ancient rocks. This opens up new interpretations of the Archean Period’s sulfur isotope sedimentary signature—a proxy for the origins and evolution of atmospheric oxygen and early life on Earth.
Using 100-year-old minerals processing methods, chemical engineering students have found a solution to a looming 21st-century problem: how to economically recycle lithium ion batteries.
A research team including Matthew Sanger, assistant professor of anthropology at Binghamton University, State University at New York, has found a copper band that indicates ancient Native Americans engaged in extensive trade networks spanning far greater distances than what has been previously thought.
The vast reservoir of carbon stored beneath our feet is entering Earth’s atmosphere at an increasing rate, according to a new study in the journal Nature. Blame microbes: When they chew on decaying leaves and dead plants, they convert a storehouse of carbon into carbon dioxide that enters the atmosphere.
Researchers at UC Santa Cruz are addressing the issues of groundwater supply and water quality with an ongoing "managed aquifer recharge" program in the Pajaro Valley, where they have been implementing and studying groundwater recharge projects and evaluating methods to improve water quality as it infiltrates into the ground.
With new and compelling evidence for water existing beneath the south pole of Mars, a West Virginia University professor says this underground lake is likely to be extremely salty and more acidic than battery acid. Life forms that can survive in extreme physical and geochemical conditions are found in abundance in acid salt lakes such as those in Chile and western Australia, she said.
In 1924, Russian biochemist Alexander Oparin claimed that life developed through chemical changes of organic molecules. The Weizmann Institute’s Prof. Doron Lancet has now made discoveries about lipids that support Oparin’s ideas. Lancet’s findings could also help identify early, lipid-based life forms on other worlds.
Scientists at the U.S. Department of Energy’s Ames Laboratory have discovered an earlier unknown discontinuous magnetoelastic transition in a rare-earth intermetallic. The mechanism of the material’s changing magnetic state is so unusual, it provides new possibilities for discovery of similar materials.
Developed by Berkeley Lab researchers, ESS-DIVE is a new digital archive that serves as a repository for hundreds of U.S. Department of Energy-funded research projects under the agency’s Environmental System Science umbrella.
The dust that coats much of the surface of Mars originates largely from a single thousand-kilometer-long geological formation near the Red Planet’s equator,
Political scientist Elizabeth Shakman Hurd comments on role of U.S. hardliners, crisis of legitimacy at home for President Trump
Researchers at Binghamton University, State University at New York have used a new image-based analysis technique to identify once-hidden North American mounds, which could reveal valuable information about pre-contact Native Americans.

One of the lead researchers of a study showing that Apollo astronauts’ activity likely contributed to slight, local lunar surface warming, would like to clear up misunderstandings that have resulted, particularly in light of the millions of views these reports have since received.
If your summer has included travel, you may have noticed a difference in the soil beneath your feet. The Soil Science Society of America (SSSA) July 15 Soils Matter blog explains why different areas have such different soil.
Sea-level rise will endanger valuable salt marshes across the United Kingdom by 2100 if greenhouse gas emissions continue unabated, according to an international study co-authored by a Rutgers University–New Brunswick professor.
Global climate trend since Dec. 1 1978: +0.13 C per decade
Earth’s oxygen levels rose and fell more than once hundreds of millions of years before the planetwide success of the Great Oxidation Event about 2.4 billion years ago, new research from the University of Washington shows.
