I’m really happy to share that my invited review on social insect genome evolution, co-authored with @corriemoreau.bsky.social, is out now in @genomebiolevol.bsky.social 🐝🐜 This is the paper I wish I’d had when studying for quals in grad school, and was a ton of fun to write.

@cellpress.bsky.social has just released an.... interesting new 'short review' on pre-implantation gene editing, in which author Cathy Tie argues for the ethical imperative of pushing for this technology. www.sciencedirect.com/science/arti... There are, to put it mildly, a few issues here. 1/
Medicine has a responsibility to develop interventions that safely reduce human suffering. Therapeutic germline gene editing should be judged by the scientific evidence supporting it, not by the history of the field. If rigorous clinical evaluation demonstrates that it is safe and effective, continued prohibition would itself require ethical justification.
