This week, I’ve been working on a big story about a controversial treatment that creates babies with three genetic parents. The “three-parent baby” technique was thought to help parents avoid passing diseases on to their kids. But new evidence suggests it doesn’t always work—and could create babies at risk of severe diseases.
The evidence comes from two babies born after the procedure was used to help couples with a different problem: infertility. It’s lucky we found the problem in these cases—these babies didn’t have parents with disease-causing mutations, so they should be fine.
Scientists at Columbia University have edited the DNA of early human embryos with unprecedented accuracy, an achievement that could open the way to babies engineered with particular characteristics.
The prospect has fueled controversy for years. On the one hand, the...
Faster, Higher, Stronger was the Olympic motto from 1874 until 2001, when “ – Together” was added, to stress the “moral and educational perspective” of the Games. The folks who paid for or participated in the Enhanced Games – the name itself a nod to the Olympics – held in Las Vegas on Sunday, May 24, apparently use a different edit:

In a small, preliminary study, an experimental gene-editing treatment dramatically lowered cholesterol levels, perhaps permanently, after just one infusion, scientists reported on Monday.
If confirmed in larger studies, researchers hope the findings may lead to a one-and-done way to prevent...
BOSTON — Over the past year, I’ve begun hearing rumblings from scientists who secretly think it’s time to stop being stodgy about editing the genes of human embryos.
For the most part, they are still too timid to speak up...
