MESSENGER discovers an unusual impact basin on Mercury
A previously unknown, large impact basin has been discovered by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft during its second flyby of Mercury in October 2008. view more (2009-05-01)
Giant Impact Near India -- Not Mexico -- May Have Doomed Dinosaurs
A mysterious basin off the coast of India could be the largest, multi-ringed impact crater the world has ever seen. And if a new study is right, it may have been responsible for killing the dinosaurs off 65 million years ago. view more (2009-10-16)
Rim of Crater Huygens on Mars
These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, show the eastern rim of the Martian impact crater Huygens. view more (2004-10-19)
Congo River Basin : Geology And Soil Type Influence Drought Impact
The Congo drainage basin is situated in Central Africa. Its hydrological system straddles several countries (Congo and the Democratic Republic of Congo for the most part, but also Angola, Cameroon, the Central African Republic, Zambia and Tanzania, stretching through Lake Tanganyika). The River Congo, the second longest African river after the... view more... (2002-01-03)
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)
MERCURY POLLUTION IN BOLIVIAN RIVERS
Mercury contamination in rivers of the Amazon Basin is increasingly a cause for concern. The region's soils, naturally containing abundant heavy metals, are one source of this mercury. Gold mining, which is an increasing activity in the Amazon region since gold fever took hold in the 1970s, is the additional major source. Many studies have been... view more... (1999-09-13)
Tiny pikas seem to be on march toward extinction in Great Basin
The tiny rabbit-like American pika, an animal species considered to be one of the best canaries in a coal mine for detecting global warming in the western United States, appears to be veering toward the brink of extinction in the Great Basin. view more (2005-12-29)
Report shows deforestation threatens Brazil's Pantanal
Deforestation from increased grazing and agriculture has destroyed 17 percent of the native vegetation in Brazil's Pantanal, considered the world's largest wetland. view more (2006-01-11)
Buried craters and underground ice-Mars Express uncovers depths of Mars
For the first time in the history of planetary exploration, the MARSIS radar on board ESA's Mars Express has provided direct information about the deep subsurface of Mars. view more (2005-12-01)
Genetics links whale to two different ocean basins
For the first time ever, a genetic study has followed a single humpback whale from one ocean basin to another, adding to traditional notions of the migratory patterns of these majestic marine mammals in the process. view more (2005-08-18)
Mountain climate change trends could predict water resources
New research into climate change in the Western Himalaya and the surrounding Karakoram and Hindu Kush mountains could explain why many glaciers there are growing and not melting. view more (2006-08-25)
Sky islands: metaphor or misnomer?
The term "sky islands" sounds intriguing, but it may be more lyrical than useful when discussing mammal distributions, according to new research from Eric Waltari of the Sackler Institute of Comparative Genomics at the American Museum of Natural History and Robert Guralnick from the University of Colorado at Boulder. view more (2008-08-14)
History and timing of human impact on Lake Victoria, East Africa
Lake Victoria, the world's largest tropical lake, suffers from severe eutrophication and the probable extinction of up to half its 500+ species of endemic cichlid fishes. New sediment-core data show that increased algal production developed from the 1930s onwards, paralleling human population growth and agricultural activity in the surrounding... view more...

The Baikal Basin Is Extending
For millions of years Lake Baikal has remained a deep-water repository of relic fauna and pure fresh water, although its basin is constantly being filled up with the alluvion brought by violent landslides, slide-rocks, mudflows and rapid tributaries. Obviously, to keep the balance the basin should extend at least by the volume of delivered... view more... (2002-05-17)
Amazon River reversed flow
Ask any South American dinosaur which way the Amazon River flows and she would have told you east-to-west, the opposite of today. That's the surprising conclusion of researchers studying ancient mineral grains buried in the Amazon Basin. view more (2006-10-25)
Assessing the Amazon River's sensitivity to deforestation
Understanding how the Amazon River varies in time, what causes those variations, and how sensitive it will be to ongoing, and accelerating, deforestation is a focus of study for scientists at the Woods Hole Research Center. view more (2005-06-21)
Plate tectonics may take a break
Plate tectonics, the geologic process responsible for creating the Earth's continents, mountain ranges, and ocean basins, may be an on-again, off-again affair. view more (2008-01-04)
Hydro-ecoregions, a natural framework for water management
The way in which a river functions depends on the nature of the terrain through which it flows, the relief, climate and human activity in the catchment. For this reason, there is wide environmental diversity in aquatic systems. Beneficial action in one place will not necessarily work elsewhere, pollution discharged into a river in Normandy will... view more... (2003-06-11)
Amazon conservation policy working in Brazil, MSU-led study finds
Contrary to common belief, Brazil's policy of protecting portions of the Amazonian forest from development is capable of buffering the Amazon from climate change, according to a new study led by Michigan State University researchers. view more (2009-06-16)
Why the Amazon rainforest is so rich in species
Tropical areas of south and central America such as the Amazon rainforest are home to some 7500 species of butterfly compared with only around 65 species in Britain. view more (2005-12-06)
