It's a chilling thought. In the coming year, 130,000 people worldwide will suffer spinal-cord injuries—in a car crash, perhaps, or a fall. More than 90 percent of them will endure at least partial paralysis. There is no cure. But after a decade of hype and controversy over research on embryonic stem cells—cells that could, among other things, potentially repair injured spinal cords—the world's first clinical trial is about to begin. As early as this month, the first of 10 newly injured...

Who wouldn't love to find a drug to help prevent or at least delay the onset of Alzheimer's disease? It turns out that one may already exist. Dr. Benjamin Wolozin, professor of pharmacology at Boston University School of Medicine, posted a study this week in the online journal BioMed Central Medicine showing that the cholesterol-lowering drug Zocor (simvastatin) reduced the incidence of both Alzheimer's disease and Parkinson's by about 50 percent in a population of 4.5 million veterans over a...

When Jan Luedecke of Toronto was arrested and tried for sexual assault, he had an unusual defense—he did it in his sleep. Really. It may sound farfetched, but Luedecke, who was 33 at his 2005 trial, had a history of sleepwalking. On the night in question, he'd been drinking at a party and found himself sacked out on the couch with a woman he'd met there. Hours later, she jolted him awake and demanded to know what he was doing. Luedecke claimed he was unaware he was having sex with her. "Under...

The common white sucker is nobody's favorite fish. It's a bottom feeder that trout fishermen in Colorado happily toss back into the water. But it's also what scientists call a sentinel—a species whose health (or lack thereof) can warn us about problems in the environment. So imagine the reaction of environmental endocrinologist David O. Norris of the University of Colorado when he discovered some alarming changes in the sucker population of Boulder Creek. Upstream, where the water flows pure...

By studying the siblings of kids with autism, researchers hope to develop new methods for diagnosing the disorder. The mysteries of social referencing.

Prostate cancer is the second leading cancer killer among men, after lung cancer. The American Cancer Society projects that in 2007 there will be 219,000 new cases and 27,000 deaths. Yet detecting the disease early has always been problematic. The only blood test available now—a test for prostate-specific antigen (PSA)—is not good at distinguishing malignancies from benign prostate enlargement (BPH). And it's useless for separating aggressive cancers from others that are so slow-growing...
