The federal government has made substantial progress recently to improve America's food safety system by adopting a new regulatory framework that focuses on prevention and clearly defines the roles industry and government must play. But reform of the system must go further and assign responsibilities more clearly, make better use of scarce resources, and prepare for future challenges, including those posed by persistent foodborne illnesses and the globalization of the food economy, according to a new article authored by the former head of USDA's Food Safety and Inspection Service. The article appears in the current Food and Drug Law Journal.

Until recently, the study of negotiation was focused on splitting up "goods," or things people want, not on the distribution of "bads." In a study by Neale, Harris Sondak of Duke University, and Robin Pinkley of Southern Methodist University, takes a close look at what factors influence people's willingness to accept burdens.
The concept of Most Favored Nation has not been lost on the business world, where corporations frequently write Most Favored Customer clauses into contracts with their largest customers, guaranteeing them the lowest price in markets where prices vary. The government has tried to capitalize on the idea, too, but in the case of Medicaid, says a Stanford researcher, it was a bad idea.
DETROIT -- We've all heard that anger can kill. Yet for cardiac patients, perhaps denial of anger is even more deadly. Denial of anger emerged as a stronger predictor for death and other cardiac incidents, such as new heart attacks or additional cardiac procedures, than traditional cardiac risk factors, according to a Henry Ford Hospital study conducted by Mark Ketterer, Ph.D.

Johns Hopkins scientists may have identified how oxidants can worsen cancerous cell growth and how antioxidants can suppress it. Antioxidants have long been thought to fight cancer; the current findings give insight into how the protection may occur and how it may be harnessed for anti-cancer therapies.
When the anti-nausea drug Thalidomide came out on the market in the late 1950s, one molecule in the drug caused terrible birth defects. That molecule was what chemists call a "chiral" molecule. Chiral molecules are molecules which are chemically and structurally the same, but are mirror images -- one is right-handed and the other is left-handed. Until now there has been no reliable way to separate right- and left-handed chiral molecules. But that is changing.
