Using Hi-Tech Tools To Rescuing Recorded Sound from Silence
August 21, 2007 01:35 PM - Kathleen M. Wong, UC Berkeley

While listening to National Public Radio in 2000, Carl Haber learned that the Library of Congress had a big problem. The Library's audio collection, which spans the 130-year history of recorded sound, includes the soaring tenor of Enrico Caruso, the speeches of Teddy Roosevelt, and the voices of Native Americans from now-vanished tribes. These echoes of a bygone era were recorded on media such as wax cylinders and shellac and lacquer discs. But many are now too fragile to play in their original format; the pressure of a stylus or phonograph needle could cause irreversible damage. The archivists needed a means to preserve the recordings without injuring them further.

August 21, 2007 01:31 PM - By Sarah Yang, UC berkeley

A compound found in broccoli and related vegetables may have more health-boosting tricks up its sleeves, according to a new study led by researchers at the University of California, Berkeley. Veggie fans can already point to some cancer-fighting properties of 3,3'-diindolylmethane (DIM), a chemical produced from the compound indole-3-carbinol when Brassica vegetables such as broccoli, cabbage and kale are chewed and digested. Animal studies have shown that DIM can actually stop the growth of certain cancer cells.

It appears in the Aug. 21 issue of the journal Current Biology.

Dense Breasts, Hormone Levels Are Risk Factors For Breast Cancer
August 21, 2007 01:16 PM - Georgetown University Medical Center, Washington

Washington, D.C.--The density of a woman’s breast tissue and her level of sex hormones are two strong and independent risk factors for breast cancer, according to a team of researchers from Harvard and Georgetown universities. The finding dispels the common belief that the risk associated with dense breasts merely reflects the same risk associated with high levels of circulating sex hormones, they say.
