Hello and welcome to Curiosity Daily from Discovery, a great place to get smarter without taking up your whole day. I'm Nate.

Hi, guys. It's so good to talk to you again. Welcome to Curiosity. We have a great time today. I'm Callie.

Today you'll learn about a new transparent solar cell that could replace your windows to power your home, the discovery of

hundreds of new mysterious Nazca glyphs, and how singing in a choir might be good for your brain.

Okay, I'm excited. Let's go. As climate change brings a new kind of chaos seemingly every week,

we are faced with a particular challenge. On one hand, we are an energy-starved world.

We've come to rely on all kinds of devices and machines and processes that suck up wild amounts

of energy, and that energy, by and large, comes from fossil fuels. On the other hand, we desperately

need to reduce the amount of carbon dioxide those fuels kick into the atmosphere.

Right. On the surface, at least, and all things being equal, it seems like a choice between

carbon emissions and energy production. Either we use less energy and decrease the amount of CO2 we produce,

which some might argue would make us face drastic changes to our way of life, or we keep

chugging along at the current

rate and face a potentially unlivable world in the future. Exactly. It's either energy

or a livable world. But as we've talked about a lot on the show, there is a third path. We find our

energy from sources that aren't billowing out CO2. And that's the path scientists from Olson National

Institute of Science and Technology in South Korea set out to explore. Renewables, right? There's solar,

wind, hydrogen. Oh, there's even been a growing interest in nuclear lately. Yes. So truthfully,

the solution probably lies in a mix of all the above because we use just a lot of

energy. But this team wanted to solve a particular solar problem that has had scientists

scrambling for years. They wanted to develop a transparent solar cell. Okay. So that sounds interesting,

but I'm not sure I understand why having a solar cell you can see through is a big deal.
