A British doctor is claiming that he has created the ability to edit DNA at the moment of conception in mice that makes human DNA editing a realistic possibility.

He says this discovery along with others in the last two years mean that scientists can seriously began to pursue creation of  “designer babies” which specific hair color, eye color and other features.

“We used a pair of molecular scissors and a molecular sat-nav that tells the scissors where to cut,” Dr. Tony Perry told the BBC.  “It is approaching 100% efficiency already, it’s a case of ‘you shoot you score’.”

He says that science fiction is no longer necessarily fiction.

“There’s much speculation here, but it’s not completely fanciful, this is not HG Wells, you can imagine people doing this soon [in animals],” Dr. Perry said.  “At that time the HFEA [the UK’s fertility regulator] will need to be prepared because they’re going to have to deal with this issue.”

Dr. Perry says that his science exists in a wider scientific community and that society as a whole should decide what is acceptable when it comes to DNA mutation.
