For nearly half a century, scientists have been trying to create a process for displacing animal parts into humans, a theoretical dream that could help the hundreds of thousands of beings in need of a lifesaving transplant. But possible risks, precisely of transmitting the PERV virus from animals to humans, have always been too great, stopping research — until now. In a mind-blowing talk, geneticist Luhan Yang explains a breakthrough: using CRISPR, a technique for editing genes, she and her colleagues have created pigs that don’t carry the virus , opening up the possibility of safely originating human-transplantable organs in boars. Learn more about this cutting-edge science and how it could help solve the organ shortage crisis.
