Solving the mystery of the Tibetan Plateau
A University of Alberta physicist who helped solve the age-old mystery of what keeps afloat the highest plateau on earth has added more pieces to the Tibetan puzzle. Dr. Martyn Unsworth has uncovered new research about the Tibetan Plateau-an immense region that for years has plagued scientists studying how the area became so elevated. view more (2005-11-04)
How rusty is the Earth?
An iron object lying around outside quickly turns rusty. Iron metal always has to be combined with some other elements or coated with paint to stop it corroding. The reason for this is that iron metal is unstable in the presence of the oxygen in the Earth's atmosphere. It reacts with the iron to produce ferric iron, a form of iron that exists in... view more... (2004-06-10)
Prelude to an Earthquake?
A geophysicist from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has identified possible seismic precursors to two recent California earthquakes, including the 1989 Loma Prieta earthquake that wreaked havoc throughout the Bay Area. view more (2005-12-12)
Iron in Northwest rivers fuels phytoplankton, fish populations
A new study suggests that the iron-rich winter runoff from Pacific Northwest streams and rivers, combined with the wide continental shelf, form a potent mechanism for fertilizing the nearshore Pacific Ocean, leading to robust phytoplankton production and fisheries. view more (2007-03-01)
Snowball Antarctica - early Drake passage opening led to global change
New results shed light on how Antarctica became the icy, barren continent that we know today. view more (2005-08-31)
MIT researchers find clues to planets' birth
Meteorites that are among the oldest rocks ever found have provided new clues about the conditions that existed at the beginning of the solar system, solving a longstanding mystery and overturning some accepted ideas about the way planets form. view more (2008-10-31)
Icy AMORE on the volcanoes of the Northern Polar Sea
The polar research vessels RV Polarstern and USCGC Healy returned after a ten week successful expedition to the high arctic regions. Together with the new US Coast Guard icebreaker, the USCGC Healy, the Polarstern, run by the Alfred Wegener Institute for Polar and Sea Research (AWI) explored the Gakkel Ridge, the most northerly extension of the... view more...

Earthquake 'memory' could spur aftershocks
Using a novel device that simulates earthquakes in a laboratory setting, a Los Alamos researcher and his colleagues have shown that seismic waves-the sounds radiated from earthquakes-can induce earthquake aftershocks, often long after a quake has subsided. view more (2008-01-04)
Plate tectonics may take a break
Plate tectonics, the geologic process responsible for creating the Earth's continents, mountain ranges, and ocean basins, may be an on-again, off-again affair. view more (2008-01-04)
Deep magma matters in volcanic eruption cycle
Although the Soufriere Hills volcano on Montserrat exhibits cycles of eruption and quiet, an international team of researchers found that magma is continuously supplied from deep in the crust but that a valve acts below a shallower magma chamber, releasing lava to the surface periodically. view more (2008-10-10)
Two other Mars missions heating up
Two Mars orbiter missions - one from NASA, the other from the European Space Agency (ESA) - will open new vistas in the exploration of Mars through the use of sophisticated ground-penetrating radars, providing international researchers with the first direct clues about the Red Planet's subsurface structure. view more (2006-03-07)
Climate change will affect carbon sequestration in oceans, model shows
The direct injection of carbon dioxide deep into the ocean has been suggested as one method to help control rising carbon dioxide levels in the atmosphere and mitigate the effects of global warming. view more (2005-09-08)
Research re-examines strong hurricane studies
Researchers at the Georgia Institute of Technology have released a study supporting the findings of several studies last year linking an increase in the strength of hurricanes around the world to a global increase in sea surface temperature. view more (2006-03-17)
'Magma P.I.' unearths clues to how crust was sculpted
About a decade ago, Johns Hopkins University geologist Bruce Marsh challenged the century-old concept that the Earth's outer layer formed when crystal-free molten rock called magma oozed to the surface from giant subterranean chambers hidden beneath volcanoes. view more (2007-12-04)
'Ultrasound' of Earth's crust reveals inner workings of a tsunami factory
Research announced this week by a team of U.S. and Japanese geoscientists may help explain why part of the seafloor near the southwest coast of Japan is particularly good at generating devastating tsunamis, such as the 1944 Tonankai event, which killed at least 1,200 people. The findings will help scientists assess the risk of giant tsunamis in... view more... (2007-11-16)
A hidden drip, drip, drip beneath Earth's surface
There are very few places in the world where dynamic activity taking place beneath Earth's surface goes undetected. view more (2009-05-27)
FSU scientists unveil new seasonal hurricane forecasting model
Scientists at The Florida State University's Center for Ocean-Atmospheric Prediction Studies (COAPS) have developed a new computer model that they hope will predict with unprecedented accuracy how many hurricanes will occur in a given season. view more (2009-07-16)
Diamonds are a urologist's best friend
Wafer-thin coatings from diamond-like carbon can prevent dangerous biofilms of bacteria from forming on indwelling catheters in the urinary tract. What is more, the coated catheters glide into the ureter with considerably less friction, to the delight of medical staff, and even more so to that of the patients, who experience the procedure as... view more...

Study highlights role of hit-and-run collisions in planet formation
Hit-and-run collisions between embryonic planets during a critical period in the early history of the Solar System may account for some previously unexplained properties of planets, asteroids, and meteorites. view more (2006-01-12)
Scientists lose instruments, gain first look at seafloor formation
Ordinarily, losing almost all of one's instruments would be considered a severe setback to any scientist. But when Maya Tolstoy, a marine geophysicist at the Lamont-Doherty Earth Observatory, a member of the Earth Institute at Columbia University, recently learned that two-thirds of the seismometers she placed on the floor of the Pacific Ocean... view more...
