Gene edits move pig organs closer to human transplantation
In this episode:
Kidneys from genetically-engineered miniature pigs have been transplanted into non-human primates, in some cases keeping the animals alive for more than a year. Using CRISPR, a team made dozens of edits to the pig genome to prevent the monkeys’ immune system from attacking the organs. They also removed pig retrovirus genes that could represent an infection risk. These steps are necessary if pig organs are to be used in human transplants, something many clinicians and researchers think will be needed to overcome a critical shortage of organs for transplantation.

19:06|Although scientists have long been able to gather DNA from water and soil, it's only recently that they've started to see the air as a source of genetic information.Airborne DNA is already being used to monitor individual species, but researchers hope its abundance could have multiple uses, including judging the success of conservation efforts or attacks with biological weapons.However, there remains much to understand, such as how far DNA travels in the air, and the ethics involved in the potential identification of a person's genetic information.This is an audio version of our Feature: The air is full of DNA — here’s what scientists are using it for
