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.
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 ...
Lab study suggests small layer of water, CO2 and silicate lies beneath tectonic plates
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.
Ammonium salts could provide viable way of removing carbon dioxide from atmosphere via carbon mineralization
Removing excess carbon dioxide (CO2) from the atmosphere may be essential to curb severe climate change. Possible, but expensive, methods include burying the gas underground between rock layers or 'scrubbing' ...
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 ...
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.
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.
Putting the squeeze on planets outside our solar system
(PhysOrg.com) -- Using high-powered lasers, scientists at Lawrence Livermore National Laboratory and collaborators discovered that molten magnesium silicate undergoes a phase change in the liquid state, abruptly ...
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 ...
Researchers analyse 'rock dissolving' method of geoengineering
(Phys.org)—The benefits and side effects of dissolving particles in our ocean's surfaces to increase the marine uptake of carbon dioxide (CO2), and therefore reduce the excess amount of it in the atmosphere, have been analysed ...
First plants caused ice ages: research
New research reveals how the arrival of the first plants 470 million years ago triggered a series of ice ages. Led by the Universities of Exeter and Oxford, the study is published today (February 1, 2012) in Nature Geoscience.
Triton: A subsurface ocean?
Neptune's largest moon Triton is most likely a captured Kuiper Belt Object. The capture of icy Triton and the subsequent taming of its orbit likely led to the formation of a subsurface ocean through tidal ...
