Kennedy's Recovery -- And a New Treatment for Brain Cancer
The story of U.S. Sen. Ted Kennedy's brain surgery at Duke University Medical Center continued to be the focus of media attention last week. The 76-year-old senator was said by his doctors to be making "an excellent recovery." He left the medical center June 9 to fly back to Cape Cod.
Meanwhile, Duke researchers reported that a vaccine under clinical trial has been found to double survival time for those who have the most common and aggressive form of brain cancer, glioblastoma multiforme.
And it appears that a drug that prevents bone loss during breast cancer therapy also substantially reduces the risk of the cancer's return. Medical researchers said this was the first large study to affirm wider anti-cancer potential for bone-building drugs called bisphosphonates.
Another study suggests that red wine may be much more potent in slowing the aging process than was previously thought. The New York Times said the study is part of a new wave of research that may increase longevity.
A new survey found that teen sexual activity in the U.S. may be increasing, after a decade-long decline, and that fewer high school students are opting to use condoms. But the survey did not provide sufficient data to indicate a definite trend, officials said.

PODCAST & VIDEO: 3D Printing Replacement Body Parts
Regenerative medicine, a fledgling field with the aim of regrowing parts from a person’s own cells, is being amplified with 3D-printing technology, which can now use organic materials to create scaffolds that cells need to grow into their final forms. Richard Wysk, a professor of industrial and systems engineering at North Carolina State University, discusses the latest successes with this research, and the timeline for creating more complicated structures.
