It's ANDi's close kinship to humans that makes this experiment at once so promising and so troubling. On one hand, the ability to manipulate the genes of a creature so similar to humans could give researchers an incredibly powerful tool for studying and perhaps someday curing human illnesses...
Doing it in monkeys, however, could save lives. For more than a decade, researchers have been working with so-called knock-out and knock-in mice--rodents that have had genes added or effectively subtracted from their genome. By observing these custom-made lab animals, researchers have gleaned invaluable information...
Of course, there would be much less need for new medications to treat heart disease if we all exercised more, watched our weight and stopped eating so much food that is high in saturated fat. Public-health experts estimate that you can reduce your risk of heart disease as much...
Now, however, explanations are coming. As scientists hack deeper into the underbrush of the human genome, they are at last beginning to understand the genetics of weight regulation--and how the whole system can go awry. With that understanding, they believe, it may be possible to develop drugs that do...
Besides AIDS and Alzheimer's disease, each the target of major vaccine research, vaccine designers are also eyeing autoimmune diseases such as rheumatoid arthritis and multiple sclerosis, in which the body in effect attacks itself. At Israel's Technion, Dr. Nathan Karin and his colleagues have created genes that order...
