An existing osteoporosis drug is the first ever found to prevent cartilage loss from osteoarthritis following injury to a joint, and may also regenerate some cartilage that has been lost to osteoarthritis, according to an early study presented today at the annual meeting of the American Society for Bone and Mineral Research in Denver. While the study was in mice, the model closely mimics human osteoarthritis that develops following knee injuries, according to the study authors.

We are encouraged by reports that are now emerging from various clinical trials of 2009 H1N1 influenza vaccines, conducted by various vaccine manufacturers. We expect additional companies to announce their preliminary trial results shortly. The early data from these trials indicate that 2009 H1N1 influenza vaccines are well tolerated and induce a strong immune response in most healthy adults when administered in a single unadjuvanted 15-microgram dose.
September 10, 2009 – Mandatory alcohol testing programs for truck and bus drivers have contributed to a significant reduction in alcohol involvement in fatal crashes, according to a new study by researchers at the Mailman School of Public Health and the Johns Hopkins Bloomberg School of Public Health.
Reducing Americans' average intake of sodium to the amount recommended by health officials could save the nation as much as $18 billion annually in avoided health care costs and improve the quality of life for millions of people, according to a new RAND Corporation study.
Successful entrepreneurs turn big ideas into successful business opportunities, but how should they protect those ideas? A new paper from North Carolina State University offers a "how-to" guide on intellectual property protection, laying out the options for budding entrepreneurs as they consider how to move forward.
Marathon runners are famed for pasta packing in the days before a big run but when tiny passerine birds set out on their epic migrations, the distances are too great to cover on the energy reserves with which they embark. Michał Wojciechowski and Berry Pinshow explain that most birds stop off en route to their destination to refuel. One of the Eurasian blackcaps' preferred refuelling stops is Midreshet Ben-Gurion, Israel, where the birds fill up on fruit and insects before setting off again.
FAIRBANKS, Alaska— Much of circumpolar Arctic research focuses on the physical, direct changes resulting from climate warming such as sea ice retreat and temperature increases. "What's understudied is the living component of the Arctic and that includes humans," said Syndonia "Donie" Bret-Harte, associate professor of biology at the University of Alaska Fairbanks and co-author of a paper to be published September 11, 2009 in the journal Science.
Using a carbon nanotube instead of traditional silicon, Cornell researchers have created the basic elements of a solar cell that hopefully will lead to much more efficient ways of converting light to electricity than now used in calculators and on rooftops.
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.
Environmental scientists estimate that China could meet its entire future energy needs by wind alone
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.
