An international team of researchers led by Queen Mary University of London have discovered that microorganisms buried in sediment beneath the seafloor can survive on less energy than was previously known to support life. The study has implications for understanding the limit of life on Earth and the potential for life elsewhere.
Scientists use a smartphone camera to easily measure soil density -- a key metric for analyzing our soils
A new analysis of sandstones from Antarctica indicates there may be important links between the generation of mountain belts and major transitions in Earth's atmosphere and oceans. A team of researchers analyzed the chemistry of tiny zircon grains commonly found in the Earth's continental rock record to determine their ages and chemical compositions. The study was published recently in the international peer-reviewed journal Terra Nova.
Geologists from Florida State University's Department of Earth, Ocean and Atmospheric Science have discovered how carbon-rich molten rock in the Earth's upper mantle might affect the movement of seismic waves.
Experts have reconstructed the depth of the Southern Ocean at key phases in the last 34 million years of the Antarctic's climate history
Rice is the most widely consumed staple food source for a large part of the world's population. It has now been confirmed that rice can contribute to prolonged low-level arsenic exposure leading to thousands of avoidable premature deaths per year.
New work uncovers new details about our Solar System's oldest planetary objects, which broke apart in long-ago collisions to form iron-rich meteorites. Their findings reveal that the distinct chemical signatures of these meteorites can be explained by the process of core crystallization in their parent bodies, deepening our understanding of the geochemistry occurring in the Solar System's youth.
A large number of the valley networks scarring Mars's surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously thought, according to new UBC research published today in Nature Geoscience. The findings effectively throw cold water on the dominant 'warm and wet ancient Mars' hypothesis, which postulates that rivers, rainfall and oceans once existed on the red planet.
Ancient sediment found in a central Texas cave appears to solve the mystery of why the Earth cooled suddenly about 13,000 years ago, according to a research study co-authored by a Texas A&M University professor.
Using precise measurements from state-of-the-art satellite-based radar that can detect the land surface rise and fall with millimeter accuracy, an ASU research team has, for the first time, tracked the entire California coast's vertical land motion. They've identified local hotspots of the sinking coast, in the cities of San Diego, Los Angeles, Santa Cruz and San Francisco, who will be at a higher flooding risk during the decades ahead of projected sea-level rise.
