nature in an experiment i really know yet why is it like so far like it sounds so simple they had no idea but now the data's i find this not only refreshing but but at some level astounding nature Welcome back to the nature podcast.

This week, how mysterious skin structures could help regeneration.

And the AI that helps with literature reviews.

Thank you. reviews. I'm Benjamin Thompson and I'm Nick Purcher-Chall. First up on the show, new research has been uncovering more about mysterious structures in the skin,

known as Reit Ridges, which could help unlock ways to help human

skin regenerate, combat aging, and may even give us clues as to why humans aren't furry.

Reet ridges are microscopic peaks and valleys found just below the surface of our skin.

They are thought to har harbor the stem cells that

can help our skin heal and seem to play a structural role in holding the different layers of

skin together. But despite this, not much has been known about them. So one of the questions has

been, what is it? And is it a vestigial structure? Do we even need it?

This is Ryan Driscoll, a skin researcher at Washington State University. Part of the reason that we

didn't know a lot about them is because there's so few models that are easily accessible

and ways to actually study it that most of the

understanding about how it works inside of us as humans is just unknown. But that may be starting

to change as Ryan and his colleagues are publishing a new study in nature that details what

may be the best animal

to model reet ridges.

And if any of you are skin researchers listening to this, you may be saying, well, there's

one animal that's an obvious candidate.
