Cancer drug dramatically shrinks prostate tumors, study finds (Science/Technology, 4 articles)

Researchers plan to recruit 90,000 people in 12 Southern states in an effort to learn why the South has become the cancer belt of the United States and why blacks have higher rates of several kinds of cancer, United Press Internationalreported. " When you look at a map of brain cancer incidence in the United States the Southeast just lights up in red Dr. Reid Thompson, of Vanderbilt-Ingram Cancer Center in Nashville said in a news release. The researchers will look at study participants' lifestyles, family medical histories and risk factors for cancer and other serious diseases, UPIreported. Scientists are hailing a new drug to treat aggressive prostate cancer as potentially the most significant advance in the field for 70 years. Abiraterone could potentially treat up to 80% of patients with a deadly form of the disease resistant to currently available chemotherapy, they say. Magnetic nanoparticles coated with a specialized targeting molecule were able to latch on to cancer cells in mice and drag them out of the body. The study's authors, researchers at Georgia Institute of Technology, hope that the new technique will one day provide a way to test for and potentially even treat metastatic ovarian cancer.

There is, however, one potential future energy source that is environmentally friendly, has essentially unlimited potential and can be cost competitive with any renewable source: space solar power. These panels would collect far more energy than land-based units, which are hampered by weather, low angles of the sun in northern climes and, of course, the darkness of night. Government scientists have projected that the cost of electric power generation from such a system could be as low as 8 to 10 cents per kilowatt-hour, which is within the range of what consumers pay now.
