One of the saltiest bodies on Earth, an analog for what water might look like on Mars, is just one piece of a larger aquifer.
The glaciers that carved Yosemite Valley left highly polished surfaces on many of the region's rock formations. These smooth, shiny surfaces, known as glacial polish, are common in the Sierra Nevada and other glaciated landscapes. Geologists at UC Santa Cruz have now taken a close look at the structure and chemistry of glacial polish and found that it consists of a thin coating smeared onto the rock as the glacier moved over it.
Reservoirs of oxygen-rich iron between the Earth's core and mantle could have played a major role in Earth's history, including the breakup of supercontinents, drastic changes in Earth's atmospheric makeup, and the creation of life, according to recent work from an international research team published in National Science Review.
A multi-disciplinary team of researchers from LMU and TUM in Munich simulated the largest, longest multiphysics earthquake simulation to date at the Leibniz Supercomputing Centre. Its work is up for best paper at SC17.
Researchers from the Camborne School of Mines have identified methods to predict the environmental and social cost of resourcing new deposits of rare earth minerals used in the production of mobile phones, wind turbines and electric vehicles.
New research from an international team has revealed why the oldest water in the ocean in the North Pacific has remained trapped in a shadow zone around 2km below the sea surface for over 1000 years.
Washington State University researchers say landslides on logged forests will be more widespread as the Northwest climate changes. In a study modelled on clear-cut lands on the Olympic Peninsula, they anticipate the climate of 2045 and conclude that there will be a 7 -11 percent increase in the land that is highly vulnerable to landslides. The researchers say their findings are applicable to the Cascade Mountain Range area as well.
Long Valley, California, has long defined the 'super-eruption.' About 765,000 years ago, a pool of molten rock exploded into the sky. Within one nightmarish week, 760 cubic kilometers of lava and ash spewed out in the kind of volcanic cataclysm we hope never to witness. A new study shows that the giant body of magma -- molten rock -- at Long Valley was much cooler before the eruption than previously thought.
A team of WSU researchers has for the first time observed and recorded the creation of hexagonal diamond under shock compression, revealing crucial details about how it is formed. The discovery could help planetary scientists use the presence of hexagonal diamond at meteorite craters to estimate the severity of impacts.
One professor who studies the earth and one who studies space came together in the pursuit to detect and define dark matter. They are one step closer. Using 16 years of archival data from GPS satellites that that orbit the earth, the University of Nevada, Reno team looked for dark matter clumps in the shape of walls or bubbles and which would extend far out beyond the GPS orbits, the solar system and beyond.
