Nitrogen loss threatens desert plant life, study shows As the climate gets warmer, arid soils lose nitrogen as gas, reports a new Cornell study. That could lead to deserts with even less plant life than they sustain today, say the researchers. Contact: Blaine Friedlander Public Release: 6-Nov-2009
Past climate of the northern Antarctic Peninsular informs global warming debate The seriousness of current global warming is underlined by a reconstruction of climate at Maxwell Bay in the South Shetland Islands of the Antarctic Peninsula over approximately the last 14,000 years, which appears to show that the current warming and widespread loss of glacial ice are unprecedented.

November 2009 story tips from the US Department of Energy's Oak Ridge National Laboratory Fuel economy ratings for the new 2010 model year automobiles are posted at www.fueleconomy.gov, which ORNL maintains for the US Department of Energy and the US Environmental Protection Agency. A team led by ORNL's Nina Balke has moved closer to developing more rugged memory and logic devices. Heavy trucks are less heavy but just as safe and rugged because of steel rail frames. A new approach to crunching massive volumes of data uses neural networks like an artificial brain. Contact: Ron Walli Public Release: 5-Nov-2009
Are the Alps growing or shrinking? The Alps are growing just as quickly in height, as they are shrinking. This paradoxical result could be proven by a group of German and Swiss geoscientists. Contact: F. Ossing Public Release: 5-Nov-2009
PTB Terahertz calibration satisfies US laser manufacturer Terahertz radiation still lies in a metrological no man's land -- a metrology gap. The Physikalisch-Technische Bundesanstalt can now close this gap. For the first time, a commercial Terahertz laser was traced back to the international system of units by measuring its output power absolutely. Therefore, this laser is the first THz laser in the field with a reliably proven output power enabled by a novel calibration capability set up at the PTB.

Airborne nitrogen shifts aquatic nutrient limitation in pristine lakes The impact of airborne nitrogen released from the burning of fossil fuels and wide-spread use of fertilizers in agriculture is much greater that previously recognized and even extends to remote alpine lakes, according to a study published Nov. 6 in the journal Science.

Genomes of biofuel yeasts reveal clues that could boost fuel ethanol production worldwide As global temperatures and energy costs continue to soar, renewable sources of energy will be key to a sustainable future. An attractive replacement for gasoline is biofuel, and in two studies published online in Genome Research, scientists have analyzed the genome structures of bioethanol-producing microorganisms, uncovering genetic clues that will be critical in developing new technologies needed to implement production on a global scale.

USC study finds big air pollution impacts on local communities Heavy traffic corridors in the cities of Long Beach and Riverside are responsible for a significant proportion of preventable childhood asthma, and the true impact of air pollution and ship emissions on the disease has likely been underestimated, according to researchers at the University of Southern California.

Common plants can eliminate indoor air pollutants Air quality in homes and offices is becoming a major health concern. Volatile organic compounds (VOCs) found in indoor air emanate from adhesives, furnishings, clothing, and solvents and have been shown to cause illnesses in people. Researchers tested ornamental indoor plants for their ability to remove harmful VOCs from indoor air. The study concluded that simply introducing common ornamental plants into indoor spaces has the potential to significantly improve the quality of indoor air. Contact: Michael W.

Study uses satellite imagery to identify active magma systems in East Africa's Rift Valley A team from University of Miami, University of El Paso and University of Rochester used Interferometric Synthetic Aperture Radar (InSAR) images compiled over a decade to study volcanic activity in the African Rift. A paper, published in the November issue of Geology, focuses on the section of the rift in Kenya. Surface deformation of four active volcanoes underscore possibility for human hazard, as well as the potential of geothermal resources. Contact: Barbra Gonzalez Public Release: 4-Nov-2009
Toward home-brewed electricity with 'personalized solar energy' New scientific discoveries are moving society toward the era of "personalized solar energy," in which the focus of electricity production shifts from huge central generating stations to individuals in their own homes and communities. That's the topic of a report by an international expert on solar energy scheduled for the Nov. 2 issue of ACS' Inorganic Chemistry, a bi-weekly journal.

Paleoecologists offer new insight into how climate change will affect organisms An article in the Proceedings of the National Academy of Science written by a team of ecologists, including Robert Booth, assistant professor of earth and environmental science at Lehigh University, examines some of the potential problems with current prediction methods and calls for the use of a range of approaches when predicting the impact of climate change on organisms.

New insight into predicting cholera epidemics in the Bengal Delta In Bangladesh cholera epidemics occur twice a year. Scientists have tried, without much success, to determine the causes -- and advance early detection and prevention efforts. Now, researchers from Tufts University have proposed a link between cholera and fluctuating water levels in the region's three principal rivers -- the Ganges, Brahmaputra and Meghna.

Snows of Kilimanjaro shrinking rapidly, and likely to be lost The remaining ice fields atop famed Mount Kilimanjaro in Tanzania could be gone within two decades and perhaps even sooner, based on the latest survey of the ice fields remaining on the mountain. The findings indicate a major cause of this ice loss is very likely to be the rise in global temperatures. Although changes in cloudiness and precipitation may also play a role, they appear less important, particularly in recent decades. Contact: Lonnie Thompson |
