I can confirm voice-verified

the late stages of pregnancy and the whole business of labour is wild. voice-verified

it's almost shocking, isn't it, to describe that relationship between mother and baby as a battle. voice-verified

But evolutionarily speaking, voice-verified

That's an incredible discovery. voice-verified

And part of that big, big question about what actually calls time on pregnancy and says it's time to get the baby out. voice-verified

And that's what we're getting into today on this episode of The World, The Universe and Us from New Scientist. voice-verified

I'm Dr. Penny Sarshae. voice-verified

So one thing you may not realize until you have a baby is that the end of pregnancy is this big, uncertain waiting game. voice-verified

So even though you have your due date, realistically, you could expect your baby to arrive somewhere in a month-long period around that voice-verified

not very useful for planning. voice-verified

And we're going to get into that. voice-verified

But then there's also this mystery of what initiates labor. voice-verified

And for a long time, we really haven't known what kickstarts that process. voice-verified

But now there's growing evidence that it's actually the immune system that presses the go switch for the onset of labor. voice-verified

And what's really exciting about that is because if we know what's actually turning it on, it could potentially give us ways to develop drugs that prevent premature birth, preterm birth. voice-verified

And also maybe to even predict exactly when you are likely to have that baby. voice-verified

So to talk about this, we're joined by Alice Klein, who also has first-hand experience of waiting for babies to come out. voice-verified

And she's been reporting on this new finding. voice-verified

Alice, why has it taken us so long to work out what actually triggers labour? voice-verified
