Lava flows reveal clues to magnetic field reversals
Ancient lava flows are guiding a better understanding of what generates and controls the Earth's magnetic field - and what may drive it to occasionally reverse direction. view more (2008-09-29)
Calculations favor reducing atmopshere for early Earth
Using primitive meteorites called chondrites as their models, earth and planetary scientists at Washington University in St. Louis have performed outgassing calculations and shown that the early Earth's atmosphere was a reducing one, chock full of methane, ammonia, hydrogen and water vapor. view more (2005-09-08)
Ice Volcanoes on Saturn's Moon Enceladus
Scientists from the Max Planck Institute for Nuclear Physics and the University of Potsdam have found ice volcanoes-or what could be called "ice geysers"-on the surface of Saturn's moon Enceladus. view more (2006-03-15)
Study uses satellite imagery to identify active magma systems in East Africa's Rift Valley
A team from the University of Miami, University of El Paso and University of Rochester have employed Interferometric Synthetic Aperture Radar (InSAR) images compiled over a decade to study volcanic activity in the African Rift. The study, published in the November issue of Geology, studies the section of the rift in Kenya. view more (2009-11-05)
Did death-dealing cyanobacteria cause the mass deaths of Messel?
In 1875 the remains of a prehistoric crocodile were found in the brown coal mine at Messel near Darmstadt; since then a large number of well preserved fossils have also been discovered. Palaeontologists have long puzzled over what could have been the reason for this annihilation of so many creatures. In the latest issue of the Pal'¤ontologische... view more... (2004-11-17)
Unlocking the secrets of the seafloor: The future of scientific ocean drilling
Close to 600 scientists from 21 countries met Sept. 23 - 25 2009 in Bremen, Germany, to outline major scientific targets for a new and ambitious ocean drilling research program. view more (2009-09-30)
Ocean's journey towards the center of the Earth
A Monash geoscientist and a team of international researchers have discovered the existence of an ocean floor was destroyed 50 to 20 million years ago, proving that New Caledonia and New Zealand are geographically connected. view more (2009-03-05)
Geoscientists from the Alfred Wegener Institute back from an expedition to Labrador Sea
Scientists from the Alfred Wegener Institute have researched the geology of the seabed in the Labrador Sea on board of the research vessel Maria S. Merian. view more (2009-07-23)
Renewed volcanic activity at the Phlegrean Fields tracked by Envisat
Satellite images acquired by ESA's Envisat satellite have revealed the volcanic region of the Phlegrean Fields, located in southern Italy near the city of Naples, has entered a new uplift phase. view more (2006-08-22)
MIT, Harvard offer solution to Mars enigma
Planetary scientists have puzzled for years over an apparent contradiction on Mars. Abundant evidence points to an early warm, wet climate on the red planet, but there's no sign of the widespread carbonate rocks, such as limestone, that should have formed in such a climate. view more (2007-12-26)
Mapping the air to safeguard your looks, the environment - and planes in flight
High air pollution does more than just irritate your lungs, research confirms it also affects the way you look. By using ESA-provided pollution maps along with ultraviolet radiation data, cosmetics firm L'Oreal plans to investigate the future possibility of producing skincare products customised for local conditions. Today the skin-ageing... view more... (2003-08-18)
Arctic Coring Expedition Continues to Yield New Clues About Climate Change
For the second time in as many months, the IODP Arctic Coring Expedition (ACEX) is making news with new analysis of ocean-floor sediments. view more (2006-08-10)
Climate studies to benefit from 12 years of satellite aerosol data
Aerosols, very small particles suspended in the air, play an important role in the global climate balance and in regulating climate change. view more (2009-11-11)
What goes down, must come up: Earth's leaky mantle
A new analysis of the processes that constantly stir the Earth's deep mantle is helping to explain how the mantle holds onto a portion of ancient noble gases that were trapped during the Earth's formation. view more (2009-05-28)
Scientists reveal fate of Earth's oceans
Scientists at The University of Manchester have uncovered the first evidence of seawater deep inside the Earth shedding new light on the fate of the planet's oceans, according to research published in Nature. view more (2006-05-11)
Oldest Known Rock on Earth Discovered
Canadian bedrock more than 4 billion years old may be the oldest known section of the Earth's early crust. view more (2008-09-29)
Hot climate could shut down plate tectonics
A new study of possible links between climate and geophysics on Earth and similar planets finds that prolonged heating of the atmosphere can shut down plate tectonics and cause a planet's crust to become locked in place. view more (2008-05-13)
Next-generation adaptive optics produces sharper Jupiter images
A two-hour observation of Jupiter using an improved technique to remove atmospheric blur has produced the sharpest whole-planet picture ever taken from the ground, according to astronomers from the University of California, Berkeley, and the European Southern Observatory (ESO). view more (2008-10-03)
Earthquake swarms not just clustered around volcanoes, geothermal regions
An earthquake swarm - a steady drumbeat of moderate, related seismic events - over hours or days, often can be observed near a volcano such as Mount St. Helens in Washington state or in a geothermal region such as Yellowstone National Park in Wyoming. view more (2006-10-26)
Earth's turbulence stirs things up slower than expected
In a simple world rivers would flow in straight lines, every airplane ride would be smooth, and we would know the daily weather 10 years into the future. But the world is not simple - it is turbulent. view more (2006-03-06)
