Yeah.

And new insights on a potential megathrust earthquake in the Pacific Northwest.

And ancient recipes discovered in prehistoric pottery.

All of that on this episode of Shortwave, the science podcast from NPR.

These bad sleep habits were true across most demographics, races, genders, grades.

And Scott, some of these kids are getting less than five hours of sleep a night.

The results are in the medical journal JAMA.

Well, the researchers tried to get at that.

This data is from the CDC's Youth Risk Behavior Survey.

This is a survey that more than 120,000 U.S.

high schoolers take every two years, answering questions about health risk behaviors like alcohol use, cannabis use, and sexual activity.

Well, the study authors say since insufficient sleep seems to be a problem plaguing most teens, there must be structural environmental factors at play here.

And they suggest broad interventions that could potentially reach most kids.

It is scary, especially if you're a person like me who lives in the Pacific Northwest above the Cascadia subduction zone.

That's a big fault.

It's normal around here to keep a supply of earthquake emergency things in your garage like bottled water and batteries.

That's right.

Researchers at the University of Washington published a study in the journal Science Advances.

They looked at the mechanics of the plates in the Cascadia Fault.

The challenge is the fault is beneath the seafloor, which makes it hard to access and to study.
