Volcanic Activity Shaped Mercury After All
Scientists have long anguished over how little is known about Mercury, the innermost of the four terrestrial planetary bodies in our solar system.   view more (2008-07-07)

Sulfur signature changes thoughts on atmospheric oxygen
Ancient sediments that once resided on a lake bed and the ocean floor show sulfur isotope ratios unlike those found in other samples from the same time, calling into question accepted ideas about when the Earth's atmosphere began to contain oxygen.   view more (2006-08-24)

Scientist proposes explanation for puzzling property of night-shining clouds at the edge of space
An explanation for a strange property of noctilucent clouds--thin, wispy clouds hovering at the edge of space at 85 km altitude--has been proposed by an experimental plasma physicist at the California Institute of Technology (Caltech), possibly laying to rest a decades-long mystery.   view more (2008-09-26)

From Europa To Sedna - Life Beneath The Ice In The Outer Solar System?
At present, we know of no worlds beyond our Earth where life exists. However, primitive organisms on our planet have evolved and adapted over billions of years, colonising the most inhospitable places. Since life seems to gain a foothold in the most hostile environments, it seems distinctly possible that living organisms could exist in... view more... (2004-03-25)

Archaeologists find earliest evidence of modern humans in Eastern Europe
A University of Arizona archaeologist is a member of a team of scientists that has uncovered new evidence that modern humans moved out of Africa and occupied parts of eastern Europe as early as 45,000 years ago.   view more (2007-01-15)

Soft body fossils of extinct 'lamp shell' digitally reconstructed
A team of American and British scientists have identified and digitally reconstructed the first example of a fossilized brachiopod complete with its pedicle, the stalk attaching it to the sea floor, and its lophophore or feeding organ.   view more (2005-08-18)

Sand dunes tell tale of volcanic devastation
University of Leicester scientists have made a unique discovery at an Atlantic island popular with British holidaymakers. They have uncovered giant sand dunes on Tenerife that tell a tale of terrifying destruction in ancient times, when fiery clouds swept right across the island, leaving very little in their wake. Volcanic islands - volcanoes... view more... (2004-05-06)

Without disturbances in nature the world's forests will be impoverished
The forests of the world are not the stable and unchanging ecosystems they have been assumed to be. Without the occurrence of wide-spread disturbances in nature, such as forest fires, icing, or volcanic activity, forests will eventually be impoverished, owing to a lack of phosphorous. This is shown in a study reported in this week's issue of the... view more... (2004-06-21)

Off the shelf maps help mitigate volcanic hazards
When volcanoes erupt, pinpointing the regions at high risk for lethal hazards and deciding whether or not to evacuate a resistant population comprise the most difficult problems faced by hazards managers. Now a team of volcanologists has a program that maps potential problem areas quickly, taking much of the guesswork out of decision making and... view more... (2009-01-22)

Study breaks ice on ancient Arctic thaw
A new analysis of ocean-floor sediments collected near the North Pole finds that the Arctic was extremely warm, unusually wet and ice-free the last time massive amounts of greenhouse gases were released into the Earth's atmosphere - a prehistoric period 55 million years ago.   view more (2006-08-10)

Evidence from Hawaiian volcanoes shows that Earth recycles its crust
A geologist at Rutgers, The State University of New Jersey, has come up with evidence our planet practices recycling on a grand scale.   view more (2006-11-30)

Launched – the world’s first disaster monitoring service in space
27 September 2003 The world’s first small satellite constellation dedicated to monitoring global disasters has been launched by British company, Surrey Satellite Technology Ltd. Three further satellites for Surrey’s Disaster Monitoring Constellation were launched into low Earth orbit today, 27 September 2003, at 06:09 GMT onboard a... view more... (2003-10-01)

Complex dynamics underlie bark beetle eruptions
Forest management that favors single tree species and climate change are just two of the critical factors making forests throughout western North America more susceptible to infestation by bark beetles, according to an article published in the June 2008 BioScience.   view more (2008-06-02)

El Ni'ħo was more intense 4000 years ago
Examination of fossil corals on Vanuatu have enabled scientists from IRD (Institut de recherche pour le développement, ex-Orstom) based at Noumea to reconstruct the sequence of variations in sea surface temperature (SST) in the southwest Pacific Ocean that occurred over a period of 50 years, 4200 years B. P. (in the Holocene). Although... view more... (2000-11-07)

Sierra Nevada rose to current height earlier than thought, geologists say; implications for modeling global climate
Geologists studying deposits of volcanic glass in the western United States have found that the central Sierra Nevada largely attained its present elevation 12 million years ago, roughly 8 or 9 million years earlier than commonly thought.   view more (2008-04-24)

New theory for mass extinctions
A new theory on just what causes Earth's worst mass extinctions may help settle the endless scientific dust-up on the matter.   view more (2006-10-25)

Scientists explore huge volume of molten rock now frozen into the crust under the ocean's floor
For the first time scientists have mapped the layers of once molten rock that lie beneath the edges of the Atlantic Ocean and measure over eight miles thick in some locations.   view more (2008-03-28)

SMART-1 diagnoses wrinkles and excess weight on the Moon
Owing to SMART-1's high resolution and favourable illumination conditions during the satellite's scientific operations, data from Europe's lunar orbiter is helping put together a story linking geological and volcanic activity on the Moon.   view more (2007-08-23)

CAT scan reveals inner workings of volcano island
On the ground and in the water, an international team of researchers has been collecting imaging data on the Soufriere Hills Volcano in Montserrat to understand the internal structure of the volcano and how and when it erupts.   view more (2008-12-19)

Yellowstone's quiet power
A 17-year University of Utah study of ground movements shows that the power of the huge volcanic hotspot beneath Yellowstone National Park is much greater than previously thought during times when the giant volcano is slumbering.   view more (2007-03-01)
