This is how every single science fiction movie starts…
Scientists have been tinkering with the DNA in humans and other living things for decades. But one thing has long been considered off-limits: modifying human DNA in any way that could be passed down for generations.
Now, an international team of scientists reports they have, for the first time, figured out a way to successfully edit the DNA in human embryos — without introducing the harmful mutations that were a problem in previous attempts elsewhere. The work was published online Wednesday in the journal Nature.
“It’s a pretty exciting piece of science,” says George Daley, dean of the Harvard Medical School, who was not involved in the research. “It’s a technical tour de force. It’s really remarkable.”
The research is ultimately aimed at helping families plagued by genetic diseases. The new experiment used a powerful new gene-editing technique to correct a genetic defect behind a heart disorder that can cause seemingly healthy young people to suddenly die from heart failure.
