Even if the new gene has indeed made it into ANDi's reproductive cells--which can't be known until he reaches sexual maturity in four or five years--there are plenty of hurdles to creating useful research monkeys. Scientists still must learn to substitute a malfunctioning gene for the...
But the ability to replace faulty genes directly--or even add enhanced genes--and then have those changes passed on to one's descendants will eventually come. When it does, say ethicists, we'd better have policies in place to deal with it. Germline gene manipulation shouldn't necessarily be...
The scientists in Oregon have taken a tiny step toward doing what many scientists have said no scientist would ever want to do--use genetics to change, improve or enhance our children. Sticking genes into eggs and growing a healthy monkey means that someday scientists could and most likely would...
Most parents are willing to spend a lot of their money to send their kids to college, to get them piano, tennis and language lessons, to make sure they eat well and are safe. There is little reason to think that the drive to do right by our kids will...
