The great potential — and great risks — of gene editing
Recently in China, scientists genetically engineered a beagle to double its muscle mass. The scientists juiced up the aptly named Hercules by “editing” a gene called myostatin. While scientists have been able to edit genes for some time, the advent of a powerful tool called CRISPR has made gene editing — the insertion, deletion or modification of a gene in an organism — easier, cheaper and more precise. Although the case of the super-beagle raises potential ethical considerations related to the implications of inducing such dramatic changes in an animal, it also points to a broader set of issues that merit wider attention.… Seguir leyendo »
