Scientists have developed a way to keep embyros alive outside of a womb for days longer than before, by using a mix of amino acids, hormones, and growth factors:
Zernicka-Goetz says being able to go past the previous limit is "extremely important" from a scientific point of view. That's because the seventh day of development is the time when the human embryo becomes embedded within the body of the mother — when it becomes implanted in the womb. Scientists had thought embryos could only keep developing if they were safely in the womb and receiving instructions from the mother's body.
But the embryos in the studies implanted in the dish like they they would in the womb. Then they started organizing themselves into the very early stages of different complex organs and tissues and structures in the body, the researchers report.
A commentary accompanying the research urges regulators to revisit the "14-day rule":
In principle, these two lines of research could lead to scientists being able to study all aspects of early human development with unprecedented precision. Yet these advances also put human developmental biology on a collision course with the '14-day rule' — a legal and regulatory line in the sand that has for decades limited in vitro human-embryo research to the period before the 'primitive streak' appears. This is a faint band of cells marking the beginning of an embryo's head-to-tail axis. The 14-day rule has been effective for permitting embryo research within strict constraints — partly because it has been technologically challenging for scientists to break it. Now that the culturing of human embryos beyond 14 days seems feasible, more clarity as to how the rule applies to different types of embryo research in different jurisdictions is crucial. Moreover, in light of the evolving science and its potential benefits, it is important that regulators and concerned citizens reflect on the nature of the restriction and re-evaluate its pros and cons.

That's the idea, demonstrate to as many females as possible that you respect women. You can't risk being accused of not respecting women, or your life will be over. Women control social everything, and in our social times, you must appear to respect women, or you will be utterly destroyed by vengeful bitch cunts.

*YAWN*
Whatever it is that you mumbled, I'm afraid that I just didn't catch it. If it's important enough, I supposed you'll repeat yourself.

Well, ok. Runaway's comment could be read in that manner. I guess. Personally I was just confused by why he felt the need to forward this to every cisfemale hunny he knows or how this is relevant at all to the cisfemale hunnies.
Here's what's going to bake your noodle later on! What happens when cisfemale hunnies no longer have a monopoly on reproduction? Feminism, as I know it at least, is going to do everything possible to stop that inevitability from happening. And naturally, conservative Christians will be right with them.
So I guess, having wrote that, now I'm really confused by why Runaway forwarded this to cisfemale hunnies. I don't know. I don't understand everything. Something about pegs and holes but that's too close to trying to go for a dirty joke.
At any rate, I'm still waiting for feminists and conservatives to propose some kind of law that will force people who are unable to grow babies inside their bodies to have their birth certificate reissued with a big M by "gender." At least, that's what would happen if the world were fair. It's the only way to do what the North Carolina bathroom law wishes to do. (Because what it's actually done, if it ever gets enforced, well... I guess I'll probably just continue to be flabbergasted by how immune some feminists and conservatives are to reality when they realize, to their horror, that they've just forced trans men into the women's room and given trans women who have had bottom surgery a legal reason to be in the women's room all while massively inconveniencing every cisfemale hunny who needs to take a piss. Bwahaha! Me, I'll just stick to my normal trolling of the men's room with my woman suit!)
Eh, ok, mod this to -1 as well. While absolutely factual, it's too off topic to be a troll.
