World’s first genetic modification of human embryos reported: Experts consider ethics

Chinese scientists say they’ve genetically modified human embryos for the very first time. The team attempted to modify the gene responsible for beta-thalassaemia, a potentially fatal blood disorder, using a gene-editing technique known as CRISPR/Cas9. Gene editing is a recently developed type of genetic engineering in which DNA is inserted, replaced, or removed. Here, experts weigh-in with ethical questions and considerations. —> Read More
