I think this work really underscores that we are at a turning point in human genetics. There is a growing consensus that doing good research in human genetics requires an expanded skillset (including, e.g., one that can navigate the relationship between genetics, ancestry, and pop descriptors) (1/)

livescience.com
Emerging embryo-selection technologies are currently 'little more than snake oil.' But someday, they could widen social inequities.
In the book "What We Inherit," experts unpack long-standing myths about genes and how those myths could shape public opinion around emerging embryo-selection technologies.

Lots to unpack about the 1 pivotal trial default. www.nejm.org/doi/full/10.... For now a few points: 1. FDA is not legally permitted to set policy by journal article. This must stop. 2. This is not likely to give industry much stability. FDA can decide any time that the default doesn't apply. 1/
