ORNL story tips: Oak Ridge National Laboratory neutrons investigate novel crystals' ability to capture carbon dioxide from air; gleaning valuable data from Twitter used to quickly map power outages, emergencies; ORNL's lightweight, heat-shielding graphite foam tested at Germany's Wendlestein 7-X stellarator yields positive results in fusion reactors; open source software scales up analysis of motor designs to run on supercomputers.
Princeton geophysicists Jessica Irving and Wenbo Wu used data from an enormous earthquake in Bolivia to find mountains at the base of the mantle's transition zone, located 660 kilometers below our feet. Their statistical model didn't allow for precise height measurements, but these mountains may be bigger than anything on the surface of the Earth. The researchers also examined the top of the transition zone (410 km down) and did not find similar roughness.
What are the 10 most influential, revolutionary, unexpected, or just plain amazing discoveries from EarthScope's 15-year history?
A recent NASA mission to the dwarf planet Ceres found brilliant, white spots of salts on its surface. New research led by The University of Texas at Austin in partnership with NASA's Jet Propulsion Laboratory (JPL) delved into the factors that influenced the volcanic activity that formed the distinctive spots and that could play a key role in mixing the ingredients for life on other worlds.
This year marks the 150th anniversary of the Periodic Table, and the principles that drove Dmitri Mendeleev to construct his table are still influencing today's research advances.
In order to understand the global carbon cycle, deep-sea exploration is essential, an international team led by geologists from Innsbruck concludes. For the first time, they succeeded in quantifying the amount of organic carbon transported into the deep sea by a single tectonic event, the giant Tohoku-oki earthquake in 2011. The results have now been published in Scientific Reports.
Cracks in the floating ice tongue of Petermann Glacier in the far northwest reaches of Greenland indicate the pending loss of another large iceberg.
Laboratory experiments at extreme pressures and temperatures lead to precise measurements of the sound velocity of CaSiO3 perovskite which is one of the important constituent minerals in the Earth's mantle. The measurements suggested the accumulation of the subducted oceanic crust beneath the 660 km discontinuity.
Scientists put forward new explanation as to how land bridge formed between North and South America.
A UW-led team has found that early spring rainfall warms up a thawing permafrost bog in Alaska and promotes the growth of plants and methane-producing microbes.
