...symptom of congestive heart failure, but you may have a form of the disease doctors barely understand. For years, heart failure was thought to have been caused by the heart's inability to pump blood efficiently. Now a study shows that half of all patients may have a different defect altogether: their hearts don't properly fill up with blood. Doctors still don't know how best to treat the problem, but they do know who is most likely to develop it: hypertensive women over...
...defect in some of the magnetic strips on the backs of Harvard identification cards has caused the strips to chip off, rendering the cards unusable for access into dorms or for swiping into meals...
...controversial since the death of Jesse Gelsinger in a gene-therapy trial at the University of Pennsylvania last year. Besides, scientists have much simpler ways to stave off at least some genetic diseases. Parents whose embryos have the gene for Tay-Sachs disease, for example, can test for that defect and never bring the embryo to term...
...discovery of leptin in 1994 that got the genetic study of obesity rolling, and it was Friedman's research team that was responsible. Studying the genome of a rare strain of hugely obese mice, the investigators found that all of them shared a defect in a gene that coded for a previously unknown hormone released by body fat. When a normal animal gains too much weight, the hormone signals the brain to turn down the appetite rheostat. When fat stores drop, the hormone is shut off, causing appetite to rebound. In the gene-damaged mice, there was no leptin...
Perhaps like many consumers, John Benjamin, 36, a credit analyst from Oak Park, Ill., is experiencing the new wealth defect. He plans to shell out 30% less for gifts this year. "My spending habits are correlated to the performance of the market," he says. Others' behavior is correlated to their credit-card debt--and after a decade of buying, and saving next to nothing, Americans are cleaning up their balances...
