Radiofrequency ablation safe and effective for reducing pain from bone
Image-guided radiofrequency ablation (RFA), a minimally invasive cancer treatment which can be performed in the outpatient setting, significantly reduced the level of pain experienced by cancer patients with bone (osseous) metastases, limiting the need for strong narcotic pain management, and supporting improved patient frame of mind, according to new results. Postmenopausal Women With Higher Testosterone May Have Greater Heart D
Postmenopausal women who have higher testosterone levels may be at greater risk of heart disease, insulin resistance and the metabolic syndrome compared to women with lower testosterone levels, according to a new study. This new information is an important step, say researchers, in understanding the role that hormones play in women's health. Economists Find Current Biofuel Potential In Oregon May Be Costly And
The adoption of biofuels in Oregon, USA, could reduce the state's fossil fuel use by less than one percent, but at a much higher cost to society than more direct approaches such as a gasoline tax or raising fuel economy standards. The study compared three types of biofuels -- corn ethanol, canola biodiesel, and wood-based (cellulosic) ethanol. Computer Scientists Discover New Way To Spin Up Pulsars
A team of scientists using Oak Ridge National Laboratory supercomputers has discovered the first plausible explanation for a pulsar's spin that fits the observations made by astronomers. Nobel Prize in Chemistry 2006
The award goes to pioneers in the field!More info on the Nobel site and my write-up next week under the Intute Spotlight. Radio Waves Fire Up Nanotubes Embedded In Tumors, Destroying Liver Can
Cancer cells treated with carbon nanotubes can be destroyed by non-invasive radio waves that heat up the nanotubes while sparing untreated tissue, scientist have found. Plastic Surgery To Restore Facial Defects
Insurance companies may deem reconstructing severe facial deformities in children with mental disabilities as cosmetic surgery and refuse to cover them. However, craniofacial plastic surgery, to correct abnormalities of the face, skull and neck, may give these children significant psychological, social and emotional benefits that can help them attain a better quality of life, according to a report in the August issue of Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons (ASPS).

Bacteria 'Launch A Shield' To Resist Attack
Bacteria that cause chronic lung infections can communicate with each other to form a deadly shield against the body's natural defenses. Studying these interactions could lead to new ways of treating bacteria that are resistant to antibiotics. Rising Tides Intensify Non-volcanic Tremor In Earth's Crust
For more than a decade geoscientists have detected what amount to ultra-slow-motion earthquakes under Western Washington and British Columbia on a regular basis, about every 14 months. Such episodic tremor-and-slip events typically last two to three weeks and can release as much energy as a large earthquake, though they are not felt and cause no damage.Researchers find evidence that slow-slip events, essentially ultra-slow-motion earthquakes, are affected by the rise and fall of ocean tides.
