...Michael Roizen, chairman of critical care at the University of Chicago and author of RealAge: Are You as Young as You Can Be? (HarperCollins), echoes the same theme. "We really can slow the pace of aging--and even reverse it," he writes. Roizen shows how our choices affect the quality of our old age. "Eating that hamburger will make you older tomorrow than if you ate that salad today. And you will be younger tomorrow if you exercise today." Some suggestions are bromide-simple: wear a seat belt, take an aspirin a day, floss your teeth daily. Others are more...
Gene therapy, simply defined, is the placement of beneficial genes into the cells of patients. By introducing the gene and consequently the protein it produces, says Inder Verma, a professor at the Salk Institute in La Jolla, Calif., "you either eliminate the defect, ameliorate the defect, slow down the progression of the disease or in some way interfere with the disease...
...critics of gene therapy dismayed by what seems to be the slow pace of progress, Anderson urges patience. "People don't understand that the development of an ordinary drug from time of concept to product is 10 years," he says. "We're talking about a revolutionary approach to therapy, and we're only eight years into...
...colon cancer: scientists believe at least three things have to go wrong for colon cancers to form. They liken the situation to a car accident. One of the genes that tells cells to divide (the accelerator) must get stuck in the "on" position. Another gene that tells cells to slow down (the brake) must be disabled. And the molecules that fix any mistakes in the DNA code (the repair crew) have to go on strike. In half of all colon cancers, the accelerator is a gene called ras, which makes a protein that stimulates cell growth. It was the ideal...
Perhaps because of Europe's deeper suspicions of Big Business, the food fight has prompted a regulatory go-slow on the Continent. One factor is the scare that erupted in 1996 over "mad cow" disease in British beef. Though the disease was caused by feeding animal parts to cows, rather than by genetic meddling, the panic left consumers extremely wary about what goes onto the family dinner table. Herbert Krach of the Swiss Small Farmers Union notes, "For years scientists assured us that feeding animal-based feeds to cattle was harmless." But the cautions also owe something to romantic...
