The hard part of children is the womb and available parents, not creating an embryo. The UK needs to finish their artificial womb work.

There are millions of couples going through IVF that fail to get viable embryos. Probably 3/4 of women over 40 fail to get any successful pregnancies, and many younger ones too.

A team of scientists at the Weizmann Institute have successfully created an 'embryo model' that closely resembles a 14-day-old human embryo, without using sperm, eggs or womb.

The question I have is why they call it a model? It is certainly not a simulation, and although it apparently started with different components they manipulated those to behave the way the normal versions do. What would happen if they implanted it in a womb?

Another commenter linked to an earlier Nature article where 'Model' is a particularly carved out word in the ethical guidelines. https://archive.ph/Xnx5n#selection-1171.0-1171.349

From an ethical standpoint, there is no reason to assert a human being created from re-embryonized adult stem cells should be any more enslaveable than any child of any parents or the younger of any pair of twins. ... of course, the flip-side of the coin is that for a certain segment of the pro-life movement, using these cells as test subjects will be equivalent to intentionally fertilizing human egg cells and then u…

From some ethical standpoint, it's absolutely fine to engineer some creature for slavery, as long as you make it ugly and forbid anyone from discovering how many chromosomes it has, and life can be much better than it is now. (Reference work of fiction omitted to prevent spoilers)

Reducing human suffering is a noble goal and infertile couples could benefit from this research. I would rather have western world make giant leaps in this field and also set the direction of ethics here rather than just banning it and leaving it up to Russia and China to conduct this sort of research in their secret facilities.

Don't worry, Russia isn't in any position for this high-tech research. Anyone who's been anywhere close to capable of doing this work has left since 2014 or 2022.

China is a bigger risk factor, but it's not like they would care about the direction of western ethics anyway.

Edit: link to my previous comment with a list of papers from the last time a similar thread was posted for those interested.

This was a busy summer for developmental biology, full disclosure that I am an author on one of these papers and my thesis work is in embryo models/early development. The Hanna group was unfortunately scooped by some unethical behavior but their model is superior to the other one in Nature by Zernicka-Goetz.
