and move through the female reproductive tract.

So I guess it could have some benefits when it comes to fertility research.

Researchers haven't really talked about that just yet.

But as you say, it might sound relatively sci-fi or literally out of this world.

But in February, scientists actually called for more research into reproductive health and space.

They said that it was urgently needed, that they need an international collaboration to try and close these knowledge gaps because I guess we don't know what the future holds.

Thank you, Katie.

Two news stories in one.

On the subject of embryos, did you know that they have extraordinary regeneration abilities?

Exactly.

For the vast majority of species, this skill is later lost in life, right?

If we lose the toe, we cannot make it grow back.

Yeah.

Although there are some animals, you know, starfishes, crabs, salamanders that can regenerate limbs as an adult, the vast majority just can't.

And frogs, our topic here today, can't.

can't grow back arms and legs despite being closely related to salamanders.

Just like what happens with us mammals when frogs get injured, the cells that rush to the wound focus on building scar tissue and not regeneration.

So it's just, it's one or another.

Right.

So scientists from Harvard and Tufts University in the US were able to make African clawed frogs rebuild the leg they amputated by using a wearable bioreactor.
