But Dr. Karin Nelson at the National Institutes of Health, as well as colleagues at other research centers, has concluded that these causes do not explain most cases of the disease.

"It's a portable, digital replacement for the cassette, to take music on the go and make your own compilations. We didn't explain it clearly." Now Sony is trying to make itself better understood. It has relaunched the Mini with a national ad campaign, hoping to spur the 10-fold increase in sales seen in last fall's test markets and help the U.S. join an expected burgeoning world market.
