In early heart development, genes work in tandem
Studying genes that regulate early heart development in animals, scientists have solved a puzzle about one gene's role, finding that it acts in concert with a related gene. Their finding contributes to understanding how the earliest stages of heart development may go awry, resulting in congenital heart defects in humans. Occurring in approximately 1 in 200 children, congenital heart defects represent the most common human birth defect. A Treasure Of Green Moss: Modern Computers To Uncover Secrets Of Duke'
It's ironic. The 230,000 specimens of bryophytes -- mosses and their cousins-- in the Duke Herbarium's massive collection may have evolved some 500 million years ago.

New research shows that a chemical compound found in many air fresheners, toilet bowl cleaners, mothballs and other deodorizing products, may be harmful to the lungs. Human population studies at the National Institute of Environmental Health Sciences (NIEHS), a part of the National Institutes of Health, found that exposure to a volatile organic compound (VOC), called 1,4 dichlorobenzene (1,4 DCB) may cause modest reductions in lung function. Why We 'Never Forget A Face'
