...puts the fruit on the list of high-risk foods that are prone to infection. But unlike the bagged spinach from the 2006 E. Coli scare, the tomatoes don't come with a traceable bar code. "When you're dealing with tomatoes, it is much, much more complex," explains Dr. David Acheson, the FDA's associate commissioner for foods. The FDA's great tomato hunt has an ever-expanding list of suspects. A salmonella victim can point to the supermarket (or restaurant) that sold the offending fruit, but that store probably sources its tomatoes from several suppliers, each of which...

"We're not quite there yet," says Acheson, "but we're getting very close." But Dr. Ian Williams, chief of the CDC's OutbreakNet team, warns that the source may never be found due to the fruit's short shelf life. "You don't expect to find an infected tomato sitting on someone's counter 10 days after the outbreak," says Williams...

"The results are interesting, and worth paying attention to," says Dr. Marilyn Albert, a neurologist at Johns Hopkins School of Medicine. Light, the study's authors suspect, works on the body's circadian clock, which is regulated by a cluster of cells in the brain's hypothalamus. Those cells release agents that, along with the hormone melatonin, help to regulate the body's sleep-wake cycle and are responsible for alerting the brain when...

"One lesson from this paper is that it shows that a lot of alternative therapies can be studied in a rigorous way," says Dr. Eugenia Chan, director of the ADHD program at Children's Hospital in Boston...
...experts sense a link between suicides and prescription-drug use - though there is also no way of knowing how many suicide attempts the antidepressants may have prevented by improving a soldier's spirits. "The high percentage of U.S. soldiers attempting suicide after taking SSRIs should raise serious concerns," says Dr. Joseph Glenmullen, who teaches psychiatry at Harvard Medical School. "And there's no question they're using them to prop people up in difficult circumstances...
