Asphalt flows from deep-sea volcanoes
New kind of volcano discovered in the Gulf of Mexico Underwater volcanoes that spew asphalt instead of lava: they were discovered in the Gulf of Mexico during an expedition of the research vessel SONNE, led by Prof. Gerhard Bohrmann of the DFG Research Center Ocean Margins. On these volcanoes the multinational team of scientists encountered a... view more... (2004-05-17)
Climate change and permafrost thaw alter greenhouse gas emissions in northern wetlands
Permafrost - the perpetually frozen foundation of North America - isn't so permanent anymore, and scientists are scrambling to understand the pros and cons when terra firma goes soft. view more (2007-08-10)
ESA to search for life, but not as we know it
This week, astrobiologists are discussing what ESA`s Huygens spaceprobe might discover when it parachutes to the surface of Saturn`s mysterious moon, Titan, in 2005. Titan possesses a rich atmosphere of organic molecules, which Huygens will analyse. Recently some scientists have begun to think that, by redefining life, in broader terms, what we... view more...

Spring agricultural fires have large impact on melting Arctic
Scientists from around the world will convene at the University of New Hampshire June 2-5, 2009, to discuss key findings from the most ambitious effort ever undertaken to measure "short-lived" airborne pollutants in the Arctic and determine how they contribute in the near term to the dramatic changes underway in the vast,... view more...

Fantastic plastic could cut CO2 emissions and purify water
A new membrane that mimics pores found in plants has applications in water, energy and climate change mitigation. view more (2007-10-12)
Study shows that targeted antibiotics lead to prolonged improvement in IBS symptoms
Researchers at Cedars-Sinai Medical Center have found that a nonabsorbable antibiotic - one that stays in the gut - can be an effective long-term treatment for irritable bowel syndrome (IBS), a disease affecting more than 20 percent of Americans. view more (2006-10-17)
Unusual microbial ropes grow slowly in cave lake
Deep inside the Frasassi cave system in Italy and more than 1,600 feet below the Earth's surface, divers found filamentous ropes of microbes growing in the cold water, according to a team of Penn State researchers. view more (2008-12-22)
North Pole's ancient past holds lessons for future global warming
Detailed information on greenhouse gasses and a subtropical heat wave at the North Pole 55 million years ago is providing information about the Earth's past as well as a portent for its future, according to reports in the June 1 issue of Nature. view more (2006-06-01)
Remote expertise for wastewater treatment
Getting expertise where it is needed in wastewater treatment is the goal of TELEMAC, which has developed remote, and local monitoring and control solutions so industries can obtain all the benefits of anaerobic waste treatment while minimising costs and complications. view more (2004-09-27)
Novel protein complex enables survival in hostile environment
Biswarup Mukhopadhyay and Eric Johnson from the Virginia Bioinformatics Institute at Virginia Tech have discovered a novel enzyme that represents an ancient detoxification system and provides a clue to the development of early metabolism on earth. view more (2005-11-17)
Arctic Coring Expedition Continues to Yield New Clues About Climate Change
For the second time in as many months, the IODP Arctic Coring Expedition (ACEX) is making news with new analysis of ocean-floor sediments. view more (2006-08-10)
Natural gas inhabited by unusual specialists
A German-American research team of biologists and geochemists has discovered hitherto unknown anaerobic bacteria in marine sediments which need only propane or butane for growth. view more (2007-09-24)
Coal-mining hazard resembles explosive volcanic eruption, study shows
Worldwide, thousands of workers die every year from mining accidents, and instantaneous coal outbursts in underground mines are among the major killers. But although scientists have been investigating coal outbursts for more than 150 years, the precise mechanism is still unknown. view more (2009-10-01)
Biogas production is all in the mixing
Engineers at Washington University in St. Louis, using an impressive array of imaging and tracking technologies, have determined the importance of mixing in anaerobic digesters for bioenergy production and animal and farm waste treatment. view more (2008-04-17)
Denver to Barcelona: Global cities and greenhouse gas emissions
Denver released the largest amount of greenhouse gases (GHG) and Barcelona the smallest amount in a new study documenting how differences in climate, population density and other factors affect GHG emissions in global cities. view more (2009-09-24)
WHEN AN EARTHWORM DOES AS MUCH DAMAGE TO SOILS AS A BULLDOZER
The transformation of wet tropical forest into pastures causes profound changes in the physical structure of soils by favouring compaction. Such densification asphyxiates the soil. It is generally attributed to the compression caused by heavy machinery used for deforestation and in the creation of pastures and subsequently to trampling by cattle.... view more... (1999-05-11)
Research points to more effective catalyst materials for petrochemical industry
Nickel oxide is a very important chemical in modern industrial processes. It is commonly used as a catalyst within the petrochemical industry in areas like the synthesis of olefin gas and the reforming reaction of methane. view more (2006-05-12)
BSE Residues: anaerobic digestion saves 45 million euros a year
The treatment of BSE residues through anaerobic digestion is, according to Quercus, the most efficient and fruitful way of resolving this environmental question. This is a biological process successfully put into practice in a national company, ITS Marques, and consists of the degradation of organic matter by microorganisms in the absence of... view more...

Scientists ponder plant life on extrasolar Earthlike planets
When we think of extrasolar Earth-like planets, the first tendency is to imagine weird creatures like Jar Jar Binks, Chewbacca, and, if those are not bizarre enough, maybe even the pointy-eared Vulcan, Spock, of Star Trek fame. view more (2007-06-20)
New petroleum-degrading bacteria found at Rancho La Brea Tar Pits in Los Angeles
Environmental scientists at UC Riverside have discovered that the Rancho La Brea tar pits in downtown Los Angeles, Calif., house hundreds of new species of bacteria with unusual properties, allowing the bacteria to survive and grow in heavy oil and natural asphalt. view more (2007-05-11)
