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.

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,

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.
Is there life on Mars? One WVU researcher is discovering ways to improve the search for life on the desert planet.
Missouri S&T has received the largest gift in its history: an in-kind donation of proprietary seismic data valued at $6.5 million from Calico Jack Holdings LLC and Zion Energy LLC, both Houston-based oil and gas exploration companies.
Lawns in the Salt Lake Valley up to 100 years old are not yet saturated in the nutrient nitrogen, which is added by fertilizer, according to a new study from University of Utah researchers. The result is surprising, since previous studies in the Eastern U.S. suggested that fertilized soil would become saturated with nitrogen within a few decades.
Carbon is a key element, weaving its way through the survival of all living things. The Soil Science Society of America (SSSA) July 1 Soils Matter blog explains how carbon gets into soil, and how climate change is making a difference.
A team from Lawrence Berkeley National Laboratory (Berkeley Lab) and Lawrence Livermore National Laboratory, both U.S. Department of Energy (DOE) national labs, is leveraging powerful supercomputers to portray the impact of high-frequency ground motion on thousands of representative different-sized buildings spread out across the California region.
Evidence from rocks in Yosemite National Park suggests that granite stored in the Earth’s crust is partially molten at 500 degrees Celsius, nearly 200 degrees lower than had previously been believed.
A University of Wisconsin-Madison study examines the geologic changes of the Maule volcanoes, located in a region in Chile that has seen enormous eruptions during the last million years
University at Buffalo researchers are using stigmergy, a biological phenomenon that has been used to explain everything from the behavior of termites and beavers to the popularity of Wikipedia, to build new problem-solving autonomous robots.
The National Science Foundation has awarded the team more than $676,ooo to study stalagmites from caves in central and southern Portugal as a means of investigating how rainfall changed over decades and centuries starting 2,500 years ago.
The scholars from Northern Arizona University found the significant and worrisome negative effects of climate change and wildfire could be mitigated with targeted forest restoration.
By integrate remote sensing data from airborne light detection and ranging (LiDAR) and Landsat 8 and Sentinel 2 satellites, doctoral student Pedro Oliveira seeks to more accurately map the height of the Brazilian Amazon forest canopy. That will help scientists better calculate how much carbon is stored there.
A team of University of Chicago scientists ran quantum simulations to develop a new model of the behavior of water at extremely high temperatures and pressures. The computational measurements, published June 18 in the Proceedings of the National Academy of Sciences, should help scientists understand water’s role in the makeup of the mantle and potentially in other planets.

Millions of years ago, powerful volcanoes pumped Earth's atmosphere full of carbon dioxide, draining the oceans of oxygen and driving widespread extinction of marine organisms. Could something similar be happening today?

Dinosaur-age fossilised remains of tiny organisms normally found in the sea have been discovered in inland, arid Australia – suggesting the area was, for a short time at least, inundated by sea water 40 million years before Australia’s large inland sea existed.
The early Earth might have been habitable much earlier than thought, according to new research from a group led by University of Chicago scientists.
A new study that reconstructs the deep history of our planet’s relationship to the moon shows that 1.4 billion years ago, a day on Earth lasted just over 18 hours. This is at least in part because the moon was closer and changed the way the Earth spun around its axis.
