This article discusses the goals of Dr Lucas Harrington and his company Preventive to conduct research into gene editing in embryos to prevent the development of "severe disease".

This article is clear and interpretable, but there are significant issues with evidence and balance:

- No other scientific experts were quoted here apart from Harrington. The other source is a legal and ethics expert (an important perspective), but is not a scientist.

- There is no mention of what "severe disease" means, and this phrase is very option to interpretation. There is a very big range of health conditions and diseases that could come under this umbrella, so being specific is important.

- There are some diseases that we know are caused by a mutation in a specific gene and if you have that mutation, you definitely develop the disease. However, most diseases don't work like this, and instead are caused by a contribution of many genes with small effects, as well as environmental factors. These specifics aren't made very clear here.

- The discussion of "super babies" is incredibly ethically controversial because this technology could be a slippery slope to eugenics. This side of the argument is not discussed.

- There is no input in this article from people who live with conditions that would be subject to the gene editing proposed here, or their families. Their opinion is incredibly important on such an ethically controversial topic.
