>> Kim: WELCOME BACK!
IT'S CALLED CRISPR, IT'S SPELLED
C-R-I-S-P-R.
AND IT MAY BE THE MOST
REVOLUTIONARY PROCEDURE YOU'VE
NEVER HEARD OF.
>> Devin: THEY REMOVE A HARMFUL
MUTATION AND TOUCHES OFF A
HEATED DEBATE.
THEY CONDUCTED THE GROUND
BREAKING RESEARCH.
AN INHERITED HEART DISEASE THAT
OFTEN LEADS TO SUDDEN DEATH IN
YOUNG ATHLETES.
THEY SUCCESSFULLY EDITED GENES
TO REMOVE THE MUTATION THAT
CAUSES THE DISEASE WHILE NOT
TRIGGERING ANY HARMFUL NOW
MUTATIONS.
THEY USE DID THE CRISPR AND
COULD EVENTUALLY HELP ELIMINATE
THOUSANDS OF INHERITED DISEASES.
SOME FEAR IT COULD BE USED TO
CREATE SO-CALLED DESIGNER
BABIES, CONTROLLING THINGS LIKE
INTELLIGENCE, HEIGHT, HAIR
COLOR, BUT SAY IT'S NOT A
POTENTIAL TO IGNORE THE GOOD.
>> BECAUSE WE WORRY ABOUT THE
INTENDED USE, YOU CANNOT BAN
GOOD PART OF THE RESEARCH INTO
THIS AREA WHERE WE'RE NOT TRYING
TO MODIFY GENES BUT CORRECT THE
MUTANT GENES TO MAKE THEM
NORMAL.
>> Devin: KICK THAT ONE AROUND
THE DINNER TABLE TONIGHT.
