Two prominent scientists, Robin Lovell-Badge and George Daley, have been amongst the most outspoken proponents of leaving the door open to heritable human genetic modification via CRISPR. While they each have articulated their reasons in somewhat different ways at times, their core reasons arguing in favor of future heritable CRISPR appear largely the same. In this post I tackle each of these arguments in favor of leaving the door open to “CRISPR babies” with science-based counterarguments. I also raise larger risks to going down …Read More
Reports are out that a scientist in China has been working to make a CRISPR baby for some time and supposedly has made twin genetically modified babies. I see this work as unethical and dangerous. Just a couple years ago when I published my book GMO Sapiens on potential use of CRISPR in a heritable manner in humans, some people said it would only happen decades down the road if at all due to technological issues. I was too worried, they said. Others said no …Read More
The news that CRISPR-Cas9 gene editing in its current form may not work in a substantial fraction of people due to many of us having immunity to Cas9 came as a shock to many, but if you think about it, maybe it’s not so surprising. I don’t see it as the end of the world. A (preprint) from a group led by Matthew Porteus started this lively discussion a few days ago. The preprint is entitled, “Identification of Pre-Existing Adaptive Immunity to Cas9 Proteins in Humans.” Some people are freaking …Read More
Below are 16 Science Twitter accounts that I think are musts to follow for those interested in transformative science and also medicine from a wide range of diverse, thought-provoking perspectives. I could list 160, but I’ve picked these 16 as a nice sampling with a lean towards those willing to take a risk in what they say or with unique views.
