Hey guys, I'm Nate, and this here is Curiosity Daily from Discovery, the best place to get smarter in just a few quick minutes.

Thank you so much for joining us here today at Curiosity. I'm

Callie. Today you'll learn about how microgravity affects sleep and

physiological rhythms, the half a billion-year-old bioluminescent octocoral and the truth about women's synchronized menstrual cycles.

All right, let's get started.

Researchers from the University of Surrey and England worked with the European Space Agency to figure out how

microgravity affects our sleep patterns and biological rhythms and the findings

suggest we've got our work cut out for us if we ever hope to wander the

solar system. So we've talked about the effect of microgravity on our muscles and other biological systems.

How is this study different?

Well, that's a great question.

I mean, it's no secret that we've adapted to thrive in Earth's gravity and that microgravity

can cause all kinds of chaos on our bodies. Previous studies have shown that

microgravity can cause immune suppression, pump up your inflammation levels,

and reduce your muscle and bone density, but this study focused more on bi rhythms.

Like the sleep cycle or circadian rhythms, that sort of thing?

Right. The primary goal was to examine changes in sleep patterns,

biological rhythms like body temp, activity,

and sleepiness, and also take a deep look

at physiological responses under simulated microgravity.

Wait, simulated microgravity? How do you simulate microgravity. Wait, simulated microgravity?

How do you simulate microgravity?
