Mars, methane and mysteries
Mars may not be as dormant as scientists once thought. The 2004 discovery of methane means that either there is life on Mars, or that volcanic activity continues to generate heat below the martian surface. view more (2009-08-10)
NASA Sun Satellites, With UNH Sensors Aboard, Poised to Launch
NASA's Solar TErrestrial RElations Observatory (STEREO) mission will dramatically improve understanding of the powerful solar eruptions that can send more than a billion tons of the sun's outer atmosphere hurtling into space. view more (2006-10-24)
Hotspots or Not? Isotopes Score One for Traditional Theory
One great beauty of plate tectonics theory is that it explains so many geological phenomena at one time. But plate tectonics could not explain the location of many volcanic islands - Hawaii, the Azores or the Galapagos Islands, often called "hotspots" - far from the edge of tectonic plates. view more (2006-12-07)
Sun's direct role in global warming may be underestimated, Duke physicists report
At least 10 to 30 percent of global warming measured during the past two decades may be due to increased solar output rather than factors such as increased heat-absorbing carbon dioxide gas released by various human activities. view more (2005-10-03)
Satellite shows regional variation in warming from sun during solar cycle
A NASA satellite designed, built and controlled by the University of Colorado at Boulder is expected to help scientists resolve wide-ranging predictions about the coming solar cycle peak in 2012 and its influence on Earth's warming climate, according to the chief scientist on the project. view more (2007-11-14)
Monitoring Yellowstone earthquake swarms
The Seismological Society of America (SSA) is an international scientific society devoted to the advancement of seismology and its applications in understanding and mitigating earthquake hazards and in imaging the structure of the earth. view more (2009-04-10)
Scientists enhance Mother Nature's carbon handling mechanism
Taking a page from Nature herself, a team of researchers developed a method to enhance removal of carbon dioxide from the atmosphere and place it in the Earth's oceans for storage. view more (2007-11-07)
Unexpected discovery about earth's core
The core of the earth doesn't look the way it was expected to. Scientists at the Royal Institute of Technology in Stockholm, Sweden , KTH, can now show that iron, under extremely high pressure, such as that found in the inner earth, takes on unexpected properties, and this can be of importance in understanding the movements of the earth, such as,... view more...

Mars meteorite similar to bacteria-etched earth rocks
A new study of a meteorite that originated from Mars has revealed a series of microscopic tunnels that are similar in size, shape and distribution to tracks left on Earth rocks by feeding bacteria. view more (2006-03-24)
Scientists Map Soils on an Extinct American Volcano
Union County New Mexico is a landscape of striking diversity. Out of expansive rangelands rise sporadic yet majestic cinder cone volcanoes and mesas preserved by basalt, part of the Raton-Clayton Volcanic Field. Capulin volcano, formed approximately 62,000 years ago, is the youngest volcano in the field. view more (2008-10-21)

Global 'sunscreen' has likely thinned, report NASA scientists
A new NASA study has found that an important counter-balance to the warming of our planet by greenhouse gases - sunlight blocked by dust, pollution and other aerosol particles - appears to have lost ground. view more (2007-03-19)
Scripps-led Global Ocean Warming Research Paper Published in Science
Research led by scientists at Scripps Institution of Oceanography at the University of California, San Diego, that describes the first clear evidence of human-produced warming in the world's oceans will be published June 2, 2005, in the peer-reviewed journal Science. view more (2005-06-03)
Ice Age survivors in Iceland
Many scientists believe that the ice ages exterminated all life on land and in freshwater in large parts of the Northern Hemisphere, especially on ocean islands such as Iceland. view more (2007-07-20)
Quakes under Pacific floor reveal unexpected circulatory system
Zigzagging some 60,000 kilometers across ocean floors, earth's system of mid-ocean ridges plays a pivotal role in many workings of the planet, from its plate-tectonic movements to heat flow from the interior, and the chemistry of rock, water and air. view more (2008-01-10)
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)
Super deep rock formation and upper mantle move in concert
European Highlight from Geophysical Research Letters (GRL) In a finding that contradicts conventional wisdom, results from a new technique to survey the super-deep upper mantle of southern Africa show that underground volcanic rock shifted with the lithospheric plates in the area. Previously, researchers thought that the motion of the two objects... view more... (2002-03-06)
Geographic isolation drives the evolution of a hot springs microbe
Sulfolobus islandicus, a microbe that can live in boiling acid, is offering up its secrets to researchers hardy enough to capture it from the volcanic hot springs where it thrives. view more (2009-05-28)
Solar-B - a new solar mission to study the dynamic Sun
A new Japanese-led solar mission with ESA participation is preparing for launch on 23 September 2006. Solar-B will study the mechanisms which power the solar atmosphere and look for the causes of violent solar eruptions. view more (2006-09-21)
International Dawn Chorus Day - Sunday 2nd May 2004
As nature lovers all over the world wake up to enjoy the enthusiastic sounds of birdsongs on International Dawn Chorus Day on 2 May, scientists at British Antarctic Survey's (BAS) Halley Research Station will listen to a very different Dawn Chorus. Each morning, as the Earth and its enveloping atmosphere turn towards the Sun, very low frequency... view more... (2004-04-29)
