MOSS LANDING, CA — Over the last two decades, marine biologists have discovered lush forests of deep-sea corals and sponges growing on seamounts (underwater mountains) offshore of the California coast. It has generally been assumed that many of these animals live only on seamounts, and are found nowhere else. However, two new research papers show that most seamount animals can also be found in other deep-sea areas. Seamounts, however, do support particularly large, dense clusters of these animals.
Blacksburg, Va. – Tomorrow's fuel-cell vehicles may be powered by enzymes that consume cellulose from woodchips or grass and exhale hydrogen.
Researchers at Virginia Tech, Oak Ridge National Laboratory (ORNL), and the University of Georgia have produced hydrogen gas pure enough to power a fuel cell by mixing 14 enzymes, one coenzyme, cellulosic materials from nonfood sources, and water heated to about 90 degrees (32 C).
It was the geological collision between India and Asia millions of years ago that created one of the world's most distinctive places: The area around Lake Baikal in Siberia, which contains 20 per cent of the world's fresh water reserves and a unique display of plant- and wildlife.
That is the conclusion reached by two Danish researchers from the University of Copenhagen, Professor Hans Thybo and PhD Christoffer Nielsen, after many seismic examinations, including blowing up tons of dynamite, and five years work of analysing the data.
COLUMBIA, Mo. – More than 20 million tons of plastic are placed in U.S. landfills each year. Results from a new University of Missouri study suggest that some of the largely petroleum-based plastic may soon be replaced by a nonpolluting, renewable plastic made from plants. Reducing the carbon footprint and the dependence on foreign oil, this new 'green' alternative may also provide an additional cash crop for farmers.
By controlling emissions of fossil fuels we may be able to greatly delay the start of the next ice age, new research from the Niels Bohr Institute at University of Copenhagen concludes. The results have been published in the scientific magazine, Geophysical Research Letters.
MADISON — Taking a chemical approach, researchers at the University of Wisconsin-Madison have developed a two-step method to convert the cellulose in raw biomass into a promising biofuel. The process, which is described in the Wednesday, Feb. 11 issue of the Journal of the American Chemical Society, is unprecedented in its use of untreated, inedible biomass as the starting material.
Boulder, CO, USA - March-April GSA BULLETIN studies include new findings on Mars; flood-driven sedimentation effects on a Kauai coral reef; New Mexico fossil soils and Earth's ancient atmosphere; the rocks of Mount Everest, including the famous Yellow Band carbonate; evidence that sand grains from the ancestral Appalachian belt now make up the scenic cliffs of Arches, Canyonlands, Capitol Reef, and Zion National Parks on the Colorado Plateau; and metamorphic rocks along the deepest river gorge in the world.
Bethesda, MD (February 10, 2009) – Digestive, liver and pancreatic diseases result in more than 100 million outpatient visits and 13 million hospitalizations annually at a cost of $141.8 billion. A new report commissioned by the National Institutes of Health finds that costs, doctor visits, prescription costs and hospitalizations related to digestive diseases have risen significantly in recent years. The Burden of Digestive Diseases in the United States report is summarized in Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute.
The economy isn't just squeezing the middle class on land, it's also affecting fish.
According to a study by the Wildlife Conservation Society (WCS) and other organizations, researchers discovered a surprising correlation between "middle class" communities in Eastern Africa and low fish levels. Curiously, areas with both low and high socio-economic levels had comparatively higher fish levels.
Scientists have found proof in Bermuda that the planet's sea level was once more than 21 meters (70 feet) higher about 400,000 years ago than it is now. Their findings were published in the journal Quaternary Science Reviews Wednesday, Feb. 4.
