What harm can a simple road do in a pristine place such as Ecuador's Yasuni National Park, home to peccaries, tapirs, monkeys and myriad other wildlife species? A great deal, it turns out. Specifically, it can turn subsistence communities into commercial hunting camps that empty rainforests of their wildlife, researchers from the Wildlife Conservation Society and the IDEAS-Universidad San Francisco de Quito in Ecuador have found.
Cambridge, Mass. – September 10, 2009 – A team of environmental scientists from Harvard and Tsinghua University demonstrated the enormous potential for wind-generated electricity in China. Using extensive metrological data and incorporating the Chinese government's energy bidding and financial restrictions for delivering wind power, the researchers estimate that wind alone has the potential to meet the country's electricity demands projected for 2030.
CAMBRIDGE, Mass. – A team of archaeologists and paleobiologists has discovered flax fibers that are more than 34,000 years old, making them the oldest fibers known to have been used by humans. The fibers, discovered during systematic excavations in a cave in the Republic of Georgia, are described in this week's issue of Science.
SAN FRANCISCO, CA – SEPTEMBER 10, 2009 -- In addition to breaking news and new research data from clinical trials, investigations and registries, TCT (Transcatheter Cardiovascular Therapeutics) 2009, the largest global medical and scientific symposium dedicated to interventional cardiovascular medicine, will feature an important discussion led by national experts on Electronic Health Records (EHR).
Linda managed to power up to hurricane status at 11 p.m. EDT last night (September 9), and she's running into cooler waters and wind shear, so she's not expected to hold that strength through tomorrow. Microwave imagery from NASA's Aqua satellite revealed a 10 percent opening in her eyewall and that's a clue that the storm can weaken.
The blind and visually impaired often rely on others to provide cues and information on navigating through their environments. The problem with this method is that it doesn't give them the tools to venture out on their own, says Dr. Orly Lahav of Tel Aviv University's School of Education and Porter School for Environmental Studies.
DALLAS – Sept. 10, 2009 – When a terrorist bomb explodes, a tornado rips through a town, a hurricane devastates a region, or wildfires ravage homes and businesses, plastic surgeons are not typically atop the list of emergency responders.
But they should be, UT Southwestern Medical Center plastic surgeons and disaster experts recommend in the September issue of Plastic and Reconstructive Surgery.
Researchers at The University of Nottingham have a new weapon in their arsenal of tools to push back the boundaries of science, engineering, veterinary medicine and archaeology.
Anyone who has picked dandelions as a child will be familiar with the white liquid that seeps out of the stalks as you break them off. Viscous, sticky – and a much sought-after material: natural latex. Around 30,000 everyday products contain natural rubber, everything from car tires, catheter tubes, latex gloves to tops for drinks bottles. Car tires, for instance, would not be elastic enough without the incorporation of natural rubber. The bulk of this material comes from rubber trees in Southeast Asia.
