The World, the Universe and Us · The Mystery of Childbirth Is Finally Being Unravelled · 16 Sep 2026 podcast

And why has there been such a mystery around it? voice-verified

So how did they do that then? voice-verified

livestock. voice-verified

Inject them into a cell that needs a bit of voice-verified

Just amazing. voice-verified

So does that mean then compared to other mammals, our labor seems to be triggered by this sort of injection or shuttling of mitochondria rather than the drop in progesterone you mentioned? voice-verified

So voice-verified

It's interesting, isn't it? voice-verified

Because there's also evidence that the immune system might be involved in human menstruation as well, triggering the mast off of the cells that enable the shedding of the lining. voice-verified

So clearly the immune system and the uterus in people, in humans, have a close relationship that we're only just beginning to understand. voice-verified

But anyway, in regards to the labor activation stuff, can we use this? voice-verified

Can we kind of apply this to pregnancies in some way? voice-verified

And that would be great, wouldn't it? voice-verified

Because preterm births, which are ones that occur before 37 weeks, there are all kinds of problems. voice-verified

Organs might not yet be fully formed yet. voice-verified

There can be various health and developmental issues that happen with preterm babies. voice-verified

There are already drugs, though, aren't there, that you can give people if they start to go into labour too early? voice-verified

And then what about this unpredictability of when you give birth? voice-verified

Is there any way we could use this to develop like a blood test that could tell you where your immune cells are at and how soon voice-verified

Let's talk about one aspect then of maternal fetus conflict, which is why we actually give birth when we do to babies that are simultaneously like big and really painful to deliver, voice-verified
