Twenty days after the announcement, many questions remain. The one certainty seems to be that the first CRISPR babies are less breaking news than expected.
They will be in front pages again, probably, if and when the scientific paper gets published, if and when the baby-editor He Jiankui resurfaces, if and when the first photos of Lulu and Nana are circulated. But if the coverage of Dolly the sheep is considered in comparison, there’s no match. Why?
The media world has changed dramatically in the meantime, CRISPR is still unknown to many, China is perceived as a Wild East where anything can happen. But a sheep is always a sheep, and babies are babies. We should care about the first edited kids more than that. Maybe people are less troubled by human genome editing than most bioethicists. Perhaps the media have had enough of Gattaca, Frankenstein, and the likes. Did we cry wolf too often yesterday to get people interested today?
Just imagine you could find them all on the supermarket shelves, would you buy rice labeled as CRISPR or GMO, or stick to conventional non-genetically modified rice? And what price would you consider fair? Aaron Shew and colleagues from the University of Arkansas conducted a multi-country assessment of willingness-to-pay for and willingness-to-consume a hypothetical CRISPR-produced food and published their findings in Global Food Security.

Spring in Japan is pink as cherry blossoms, but summer turns violet as the flowers of a climbing plant frequently grown in the gardens of the Rising Sun. It is a kind of morning glory, of the Ipomoea nil species, locally known as Asagao. This plant had its genome sequenced in 2016 and is now inaugurating the CRISPR era in floriculture.

It’s mid-August, but CRISPR never goes on vacation. Not to be missed this week is the Science paper by George Church’s team. They have cloned 15 PERV-free piglets, meaning porcine retrovirus sequences have been edited out. The animals can now “serve as a foundation pig strain, which can be further engineered to provide safe and effective organ and tissue resources for xenotransplantation,” researchers write. According to the Harvard geneticist, the first pig-to-human transplants could occur within two years. Another article in the same journal feels the pulse of public perception of human genome editing, concluding that opinions are nuanced and the challenge is to find the best way to engage people in discussions about genome-editing regulation.
The destiny of new technologies greatly depends on their social acceptance. It makes sense, therefore, to try to understand whether the editing metaphor could make CRISPR appear more reassuring than other approaches to genetic modification. This idea has gained some ground and was discussed by several bioethicists in the American Journal of Bioethics. However, it is still an unproven hypothesis. A contribution to the debate comes from the journal Frontiers in Public Health, with a study suggesting that biotech metaphors have little impact on public perception. Continue reading
