University of Leicester professor adds new perspective to rainforest debate

The Head of Geography at the University of Leicester has addressed an international conference in Brazil on the use of modern radar technology for monitoring the rainforests.

Professor Heiko Balzter told 200 scientists and foresters in Brazil "We need advanced radar satellites for monitoring tropical deforestation and forest biomass".

The researchers from South America, the US, Canada and Europe had come together for the 8th Seminar on Remote Sensing and Geographical Information Systems Applications in Forest Engineering in the city of Curitiba, Brazil.

Volcanoes may have provided sparks and chemistry for first life

GREENBELT, Md. - Lightning and gases from volcanic eruptions could have given rise to the first life on Earth, according to a new analysis of samples from a classic origin-of-life experiment by NASA and university researchers. The NASA-funded result is the subject of a paper in Science appearing October 16.

When it comes to forest soil, wildfires pack 1-2 punch

For decades, scientists and resource managers have known that wildfires affect forest soils, evidenced, in part, by the erosion that often occurs after a fire kills vegetation and disrupts soil structure. But, the lack of detailed knowledge of forest soils before they are burned by wildfire has hampered efforts to understand fire's effects on soil fertility and forest ecology.

SRNL's microbes useful for for environmental cleanup and oil recovery

A unique, patent-pending collection of microbes that can be used both for cleaning up the environment and addressing our energy needs has earned the U.S. Department of Energy's Savannah River National Laboratory kudos from a newsletter covering the rapidly expanding field of nanotechnology.

Einstein's relativity survives neutrino test

BLOOMINGTON, Ind. -- Physicists working to disprove "Lorentz invariance" -- Einstein's prediction that matter and massless particles will behave the same no matter how they're turned or how fast they go -- won't get that satisfaction from muon neutrinos, at least for the time being, says a consortium of scientists.

Diatom genome helps explain success in trapping excess carbon in oceans

WALNUT CREEK, Calif.— Diatoms, mighty microscopic algae, have profound influence on climate, producing 20 percent of the oxygen we breathe by capturing atmospheric carbon and in so doing, countering the greenhouse effect. Since their evolutionary origins these photosynthetic wonders have come to acquire advantageous genes from bacterial, animal and plant ancestors enabling them to thrive in today's oceans.

Origin of Alps-size Antarctic mountain range unknown

A U.S.-led, multinational team of scientists this month will investigate one of the Earth's last major unexplored places, using sophisticated airborne radar and ground-based seismologic tools to virtually peel away more than 2.5 miles of ice covering an Antarctic mountain range that rivals the Alps in elevation.

EPA's stormwater program needs a significant overhaul

WASHINGTON -- Radical changes to the U.S. Environmental Protection Agency's stormwater program are necessary to reverse degradation of fresh water resources and ensure progress toward the Clean Water Act's goal of "fishable and swimmable" waters, says a new report from the National Research Council. Increased water volume and pollutants from stormwater have degraded water quality and habitats in virtually every urban stream system.

US-led, international AGAP team poised to probe 1 of Antarctica's last unexplored places

A U.S.-led, multinational team of scientists from six nations will pierce the mysteries of one of the globe's last major unexplored places this month. Using sophisticated airborne radar and other Information Age tools and techniques, the scientists will virtually "peel away" more than four kilometers (2.5 miles) of ice covering an Antarctic mountain range that rivals the Alps in elevation, and which current scientific knowledge suggests shouldn't be there at all.

Study finds high mortality of endangered loggerhead sea turtles in Baja California

SANTA CRUZ, CA--Along the southern coast of Baja California, Mexico, scientists have been counting the carcasses of endangered sea turtles for a decade as part of an effort to assess and eliminate threats to loggerhead sea turtle populations. Their findings, published this week, are shocking: almost 3,000 sea turtles were found dead along a 27-mile stretch of coast during a five-year period from 2003 to 2007.

More flexible method floated to produce biofuels, electricity

WEST LAFAYETTE, Ind. - Researchers are proposing a new "flexible" approach to producing alternative fuels, hydrogen and electricity from municipal solid wastes, agricultural wastes, forest residues and sewage sludge that could supply up to 20 percent of transportation fuels in the United States annually.

Lunar prospecting robot to be field tested on Hawaii's Mauna Kea

PITTSBURGH—The cool, rocky slopes of Mauna Kea, a dormant volcano that is Hawaii's highest mountain, will serve as a stand-in for the moon as researchers from Carnegie Mellon University's Robotics Institute, NASA and other organizations test a robot designed for lunar prospecting.

Tropical rainforest and mountain species may be threatened by global warming

STORRS, CT – Contrary to conventional wisdom, tropical plant and animal species living in some of the warmest places on Earth may be threatened by global warming, according to an article by University of Connecticut Ecologist Robert K. Colwell and colleagues in this week's (Oct. 10) issue of Science magazine.

Volcanic eruptions more complex and harder to predict, according to new Science paper

New research by a team of US and UK scientists into volcanoes has found that they function in a far more complex way than previously thought, making future eruptions even harder to predict.

The findings by scientists at the University of East Anglia (UEA) in the UK and Penn State University and the University of Arkansas in the US, will be published in the journal Science on Friday October 10.

Bold traveler's journey toward the center of the Earth

BERKELEY, CA – The first ecosystem ever found having only a single biological species has been discovered 2.8 kilometers (1.74 miles) beneath the surface of the earth in the Mponeng gold mine near Johannesburg, South Africa. There the rod-shaped bacterium Desulforudis audaxviator exists in complete isolation, total darkness, a lack of oxygen, and 60-degree-Celsius heat (140 degrees Fahrenheit).
