> to understand why so many pregnancies fail and how we might be able to prevent that from happening Are we sure that's a good idea? I've read that one of the reason for early pregnancy failure is that the embryo is not fit enough and it would be a waste of time and resources to commit to it. Another very counterintuitive finding is that if you try to implant embryos in various tissues (brain, liver, ...), the one in…

That might be true, but I know for a fact it’s a truism that doctors tell women to not feel as bad about miscarriages. My wife has had multiple miscarriages, to the point where it’s expected. Until doctors are informed of her history, they always say “the embryo wasn’t healthy enough to survive on its own …” My wife has a number of hormonal issues, but doctors can’t find a single diagnosis. But it’s certainly not wea…

Could it be nutrition?

This really is pretty amazing work. But, to the uninitiated, there's a dark side; I overheard someone commenting about an earlier post about this experiment, thinking it's possible to get out a chemistry set and just make a living thing. To be clear, they started with stem cells, and teased them into doing the right thing - they did not create a new living artifact from scratch; > Instead, they used stem cells - the…

Wouldn’t the living artifact that results from this embryo just be horribly incompatible with life and die quickly or at best live for a brief time before expiring?

The OP posted an entirely mainstream hypothesis. Let's not gatekeep and rely on credentialism.

Certain gates need to be kept. Not all gatekeeping is bad.

Possibly? I expect we'll figure out how to do this with a high chance of success within the next few decades if not sooner, unless for some reason every country capable of supporting the research bans it.

Not in the generic “eat better” sense.

There are some diets that can affect hormones/cycles, but it’s eating special foods, not laying off the ice cream.

No name for this research project was mentioned- may I suggest the Nexus-0?

Replicant number zero. This research is terrifying to me because life is never within our control.

What kind of life is it if a mouse or human is reproduced without parents.
