New definition could further limit habitable zones around distant suns
As astronomers gaze toward nearby planetary systems in search of life, they are focusing their attention on each system's habitable zone, where heat radiated from the star is just right to keep a planet's water in liquid form. view more (2009-06-11)
New report presents strongest evidence yet of human link to global warming, Duke expert says
Evidence presented in the first phase of the Intergovernmental Panel on Climate Change's 4th Assessment Report, released today in Paris, paints the clearest picture yet that human-derived greenhouse gases are playing a significant role in observed global warming. view more (2007-02-02)
Rushing fireball developed its own form of sugar digestion
Microbiologists from Wageningen have discovered a strange form of digestion in an exotic microorganism. The rushing fireball, Latin name Pyrococcus furiosus, has reinvented the wheel for several steps of sugar digestion. Pyrococcus furiosus, which was discovered 15 years ago on an Italian volcanic island, digests sugar somewhat differently from... view more... (2002-04-18)
Model gives clearer idea of how oxygen came to dominate Earth's atmosphere
A number of hypotheses have been used to explain how free oxygen first accumulated in Earth's atmosphere some 2.4 billion years ago, but a full understanding has proven elusive. view more (2005-08-09)
Ancient DNA provides clues to the evolution of social behavior
A rare Patagonian rodent known as the colonial tuco-tuco fascinates biologists because it seems to defy all odds. This threatened species has so little genetic diversity that the slightest whiff of climate change or disease should have wiped it off the face of the earth long ago. view more (2006-04-21)
'Nymph of the sea' reveals remarkable brood
The scientists discovered the mother complete with her brood of some 20 eggs and 2 possible juveniles inside, together with other details of her soft part anatomy including legs and eyes. view more (2006-11-27)
Regional nuclear war could devastate global climate
Even a small-scale, regional nuclear war could produce as many direct fatalities as all of World War II and disrupt the global climate for a decade or more, with environmental effects that could be devastating for everyone on Earth, university researchers have found. view more (2006-12-11)
African Desert Rift Confirmed as New Ocean in the Making
In 2005, a gigantic, 35-mile-long rift broke open the desert ground in Ethiopia. At the time, some geologists believed the rift was the beginning of a new ocean as two parts of the African continent pulled apart, but the claim was controversial. view more (2009-11-03)
Cosmic bogs @ the London Catastrophes conference
You may think that peat bogs are among the least interesting places on Earth and you could be right. But according to speakers at Brunel University`s `Environmental Catastrophes` conference, that doesn`t stop them being excellent recorders of catastrophic environmental events like volcanic eruptions and cosmic influx. According to Dr Lars... view more... (2002-08-17)
Journey to the center of the earth: Discovery sheds light on mantle formation
Uncovering a rare, two-billion-year-old window into the Earth's mantle, a University of Houston professor and his team have found our planet's geological history is more complex than previously thought. view more (2008-04-11)

New Glacier Outburst Flood in Iceland
On July 9th researchers from Keele and Staffordshire Universities and the Icelandic Meteorological Office identified the source and drainage routes of a glacier outburst flood or 'jokulhlaup' which is currently draining from the western margin of Vatnajokull ice cap. The team are currently part of an Earthwatch funded project based at Skaftafell... view more... (2002-07-09)
Models play important role in understanding extreme weather
Weather is a hot topic here in Interior Alaska and a quick way to get anyone talking. Not a day goes by in winter months without some observations of temperatures, air inversions, or even a mention that the sun budged another degree above the horizon. view more (2007-03-29)
Cassini's Infrared Camera Sees Tall Mountains on Saturn's Moon Titan
The infrared-sensitive camera on NASA's Cassini spacecraft has photographed the tallest mountains ever seen on Saturn's moon, Titan. view more (2006-12-13)
Giant Deep-Sea Tubeworm's Meal Ticket Comes in as a Skin Infection
Giant tubeworms found near hydrothermal vents more than a mile below the ocean surface do not bother to eat: lacking mouth and stomach, they stand rooted to one spot. view more (2006-05-22)
Engineered weathering process could mitigate global warming
Researchers at Harvard University and Pennsylvania State University have invented a technology, inspired by nature, to reduce the accumulation of atmospheric carbon dioxide (CO2) caused by human emissions. view more (2007-11-08)
Emissions irrelevant to future climate change?
Climate change and the carbon emissions seem inextricably linked. However, new research published in BioMed Central's open access journal Carbon Balance and Management suggests that this may not always hold true, although it may be some time before we reach this saturation point. view more (2008-04-28)
Moon's Escaping Gasses Expose Fresh Surface
Conventional wisdom suggests that the Earth's moon has seen no widespread volcanic activity for at least the last 3 billion years. Now, a fresh look at existing data points to much more recent release of lunar gasses. view more (2006-11-09)
European space systems support management of natural and technological disasters
The European Space Agency, ESA, and the French Space Agency, CNES, signed a charter on 20 June 2000 to promote cooperation among space system operators in deploying their systems in the event of major natural or technological disasters. The charter was signed by Mr Antonio Rodot' , ESA's Director General, and Mr Gérard Brachet, Director... view more... (2000-06-22)
Biodiversity promotes evolutionary change
Evolutionary biologists at the University of East Anglia have discovered a new link between biodiversity and the evolution of new species. view more (2005-04-18)
