Scientists explain source of mysterious tremors emanating from fault zones
Tiny tremors and temblors recently discovered in fault zones from California to Japan are generated by slow-moving earthquakes that may foreshadow catastrophic seismic events, according to scientists at Stanford University and the University of Tokyo. view more (2007-03-15)
Tiny tremors and earthquakes provide intriguing clues about seismic activity, study finds
The elusive science of earthquake prediction has been reinvigorated in recent years with the discovery of "non-volcanic tremors"—faint vibrations that originate deep inside active fault zones. view more (2006-07-13)
Ancient Turtle Migrated from Asia to America Over a Tropical Arctic
In Arctic Canada, a team of geologists from the University of Rochester has discovered a surprise fossil: a tropical, freshwater, Asian turtle. view more (2009-02-02)
Earliest evidence of modern humans in Europe discovered by international team
Modern humans who first arose in Africa had moved into Europe as far back as about 45,000 years ago, according to a new study by an international research team led by the Russian Academy of Sciences and the University of Colorado at Boulder. view more (2007-01-12)
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)
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)
Obsidian 'trail' provides clues to how humans settled, interacted in Kuril Islands
Archaeologists have used stone tools to answer many questions about human ancestors in both the distant and near past and now they are analyzing the origin of obsidian flakes to better understand how people settled and interacted in the inhospitable Kuril Islands. view more (2009-06-23)
Global sunscreen won't save corals
Emergency plans to counteract global warming by artificially shading the Earth from incoming sunlight might lower the planet's temperature a few degrees, but such "geoengineering" solutions would do little to stop the acidification of the world oceans that threatens coral reefs and other marine life. view more (2009-06-17)
Texas A&M-Galveston professor discovers new species of marine life
Two tiny worms much smaller than a rice grain and a strange crustacean that has no eyes and poisonous fangs are among several new species of marine life discovered in an underwater cave by a Texas A&M University at Galveston researcher, who has had one of the new species named after him. view more (2009-08-28)
British oceanographers find 'smoking' submarine volcano in the Indian Ocean
At over three thousand metres down in the north-west Indian Ocean, the Carlsberg Ridge is "probably the best ridge in the world". So say excited scientists from Southampton Oceanography Centre who have just found the first evidence of hydrothermal activity in this previously unexplored area of a volcanic mid-ocean ridge. The team aboard... view more... (2003-07-29)
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)
NASA and NOAA'S GOES-14 satellite takes first full disk image
The latest Geostationary Operational Environmental Satellite, GOES-14, provided its first visible full disk image of Earth on July 27, at 2:00 p.m. EDT. The prime instrument on GOES, called the Imager, is taking images of Earth with a 1 kilometer (km) or 0.62 mile resolution from an altitude of 36,000 km (22,240 miles) above Earth's surface,... view more...

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)
NASA aims to clear up mystery of elusive clouds at edge of space
NASA is preparing to launch the Aeronomy of Ice in the Mesosphere (AIM) spacecraft, the first mission dedicated to exploration of mysterious ice clouds that dot the edge of space in Earth's polar regions. view more (2007-04-12)
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)
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)
