00:00What if curing complex genetic diseases could happen in one single step?
00:04Scientists at UT Austin just created a powerful new gene editing method that might make that possible.
00:10Right now, diseases like cystic fibrosis or hemophilia are incredibly hard to treat
00:15because they're caused by many different mutations, even within the same patient group.
00:21But this new technique changes everything.
00:23It uses retrons, DNA tools borrowed from bacteria,
00:26to replace entire damaged sections of DNA at once instead of fixing one mutation at a time.
00:33That means one treatment could work for many people with different genetic mutations.
00:37Even more impressive?
00:39Previous methods only worked in about 1.5% of cells.
00:43This new retron-based method hits 30% efficiency, and it's just getting started.
00:48It's already being used to target cystic fibrosis mutations that current therapies can't touch.
00:53And because retrons can be delivered through RNA-packed nanoparticles,
00:57it could become an off-the-shelf cure for thousands of rare mutations.
01:01This isn't just a breakthrough.
01:03It's the start of a revolution in genetic medicine.
01:05It's perfect, but this is a growing disease.
01:14Yeah.
01:14It's cool.
01:19It's not формal.
01:22It's hard.
01:27It's hard.
