Potential solution to meteorite mystery: Chondrules may have formed from high-pressure collisions in early solar system
(Phys.org) —A normally staid University of Chicago scientist has stunned many of his colleagues with his radical solution to a 135-year-old mystery in cosmochemistry. "I'm a fairly sober guy. People didn't ...
Magma in mantle has deep impact: Study suggests rocks melt at a greater depth than once thought
Magma forms far deeper than geologists previously thought, according to new research at Rice University.
New clues to the early Solar System from ancient meteorites
In order to understand Earth's earliest history--its formation from Solar System material into the present-day layering of metal core and mantle, and crust--scientists look to meteorites. New research from ...
Spitzer sees crystal 'rain' in outer clouds of infant star
(PhysOrg.com) -- Tiny crystals of a green mineral called olivine are falling down like rain on a burgeoning star, according to observations from NASA's Spitzer Space Telescope.
Tiny 3-D images shed light on origin of Earth's core
(PhysOrg.com) -- A new method of capturing detailed, three-dimensional images of minute samples of material under extreme pressures is shedding light on the evolution of the Earth's interior. Early results ...
Research on self-healing concrete yields cost-effective system to extend life of structures
Efforts to extend the life of structures and reduce repair costs have led engineers to develop "smart materials" that have self-healing properties, but many of these new materials are difficult to commercialize. A new self-healing ...
Lithium to be extracted from geothermal waste
Plants Save the Earth from an Icy Doom (w/ Podcast)
(PhysOrg.com) -- Fifty million years ago, the North and South Poles were ice-free and crocodiles roamed the Arctic. Since then, a long-term decrease in the amount of CO2 in the atmosphere has cooled the Earth. ...
Study suggests space dust carries water and organic compounds
Researchers from the University of Hawaii-Manoa (UHM) School of Ocean and Earth Science and Technology (SOEST), Lawrence Livermore National Laboratory, Lawrence Berkeley National Laboratory, and University ...
Ancient forests stabilized Earth's CO2 and climate
UK researchers have identified a biological mechanism that could explain how the Earth's atmospheric carbon dioxide and climate were stabilised over the past 24 million years. When CO2 levels became too low fo ...
Iron melt network helped grow Earth's core, study suggests
(Phys.org) —Stanford scientists recreated the intense pressures and temperatures found deep within the Earth, resulting in a discovery that complicates theories of how the planet and its core were formed.
How the newest diesel engines emit very little greenhouse gas nitrous oxide
(Phys.org) —The newest catalytic converters in diesel engines blast away a pollutant from combustion with the help of ammonia. Common in European cars, the engines exhaust harmless nitrogen and water. How ...
Researchers reveal hunter-gatherers' taste for spice
Our early ancestors had a taste for spicy food, new research led by the University of York has revealed.
Chandra sees eclipsing planet in X-rays for first time
For the first time since exoplanets, or planets around stars other than the sun, were discovered almost 20 years ago, X-ray observations have detected an exoplanet passing in front of its parent star.
