Researchers Find Poor Sleep Quality Helps Cancers Grow Faster and More Agressively

This past week scientists in the U.S. brought attention to a pair of promising treatments that could lead to a cure for AIDS.   Some lucky students in California recently got a rare opportunity to talk with astronauts in space through a video link. . Researchers in California are working with Mickey Hart who was the drummer for the classic rock band The Grateful Dead to see if exposure to rhythm could help people with neurological diseases lead a better life. And… New research from scientists in Chicago has found evidence that poor sleep quality or having frequent bouts of interrupted sleep can actually speed up and worsen the growth of cancer and diminish our immune system’s ability to control or destroy cancers that are just beginning to develop.  Today we talk with the researcher who led the study on our One on One segment. We cover these stories and more on today’s edition of VOA's science, health and technology magazine, "Science World."
