An anonymous reader sends word that a three-day summit has begun in Washington to discuss the future of genetic engineering. It has a particular focus on the CRISPR technique, which has made gene editing quicker and more robust than ever before. "The reason CRISPR is so controversial is that it works well on 'germline' cells, such as sperm, eggs and embryonic cells, and the genetic editing results in heritable traits. Many scientific organizations have called for a time-out on any experiments on human cells, fearing that this crosses into dicey ethical territory. This meeting in Washington could potentially generate a new call for restraint, or some guidelines in how to handle the explosive technology." Many scientists, lawyers, and policymakers are present at the summit to try to reach consensus on how the scientific community should proceed with such research, and how the fruits of their research should be used. Professor Alta Charo said, "The more we can have effective systems for responsible oversight for the development and deployment of a technology, the more we can take chances. We have the chance to back up at the end, and change course."
