As a self-proclaimed radical street librarian, Storybook Maze makes books appear where they're scarce. Through initiatives like free, public book vending machines and street corner story times, she eliminates book deserts — or areas with...

When you think of newer ways to make electricity, solar cells and wind turbines may come to mind. But scientists can make the stuff from just about anything. And they're working on some truly bizarre ways to generate power.

Have you ever seen a science take on the Internet that you're pretty sure is wrong, but you aren't sure how to break it down? Well good news, we are taking care of that for you! Here are just 8 of them, from climate myths to health...

An entire field of science is dedicated to identifying the perfect indoor temperature. And it's a lot more complicated than simply setting the thermostat to 21 degrees Celsius (70 degrees Fahrenheit).

The world relies on manufacturing, and manufacturing relies on heat — a massive contributor to global carbon emissions, responsible for a quarter of the world's fossil fuel use. Energy entrepreneur John O'Donnell has figured out a...

Paul Andersen introduces Anatomy and Physiology in this podcast. He starts by describing how the form of an object fits the function. He then explains the themes of homeostasis and hierarchy. He describes the four major types of tissues;...

Jessi and Squeaks enjoy the winter season by constructing a model of the Fort out of gingerbread!

In the US, people spend the overwhelming majority of their time inside buildings that burn fossil fuels, which are bad for both the environment and human health. (Think: breathing in air pollution from gas stoves, furnaces and water...

Today, Jessi and Squeaks learn about the Maillard reaction while they make some delicious caramel. Second Grade Next Generation Science Standards Disciplinary Core Idea: PS1.B: Chemical Reactions - Heating or cooling a substance may...

In 2021, the Parker Solar Probe fulfilled its mission to “touch the Sun”. But the temperature over there was millions of degrees Celsius. How did the spacecraft not melt?

The body can get a whole lot colder - but not a whole lot hotter - before we die. Why is that?

Living on the moon won't be easy, but it might be worth taking a note from our ancestors, and setting up in caves

If we’re going to send people to Mars someday, we’re going to need to be very conscious of the challenges presented in this endeavor. And at the top of that list is the ferocious nature of dust on the barren planet.

There are a lot of weird exoplanets out there, like 55 Cancri e (aka Janssen), which is probably half covered in lava. But the half that's covered in lava might not be quite the half you're thinking of.

Planck's Length is the length below which the concept of length loses its meaning. What exactly does that mean and what are the incredible implications this fact has upon our reality? To find out check out this episode of Space Time...

We’re the only primate without a coat of thick fur. It turns out that this small change in our appearance has had huge consequences for our ability to regulate our body temperature, and ultimately, it helped shape the evolution of our...

In 1964, a paleontologist named John Ostrom unearthed some fascinating fossils from the mudstone of Montana. Its discovery set the stage for what’s known today as the Dinosaur Renaissance, a total re-thinking of what we thought we knew...

A hydrogen atom is traveling high within the outermost layer of Earth's atmosphere. This particular atom first entered the exosphere millions of years ago, but today it overcomes Earth's gravitational pull and escapes, joining the...

Refrigeration and air conditioning are among the largest sources of carbon, and the refrigerants we use are greenhouse gases, too. But green refrigerants are on the way, from elastocaloric cooling to a method a bit like salting an icy road.

Supercritical water produces fire without flames, which is great for making clean drinking water from our waste in space or breaking down forever chemicals here on Earth.

Some of us can't get enough of that new car smell. But certain volatile organic compounds (VOCs) that help create this aroma are linked to cancer. While this doesn't mean new car smell definitely increases your chance of getting cancer,...

Humans may use fiber optic technology to make everything from novelty desk toys to high speed internet cables, but Nature has its own ideas. For decades, scientists have debated to what extent polar bears may use the optical properties...

Mildred Dresselhaus was a giant in the field of nanoscience. She didn't invent anything you have in your home right now, but she made it possible for us to have self-charging phones, smarter refrigerators, and more.

You'd think that the Northern and Southern Hemispheres would be basically symmetrical -- that since our planet is a ball, the climate, temperature, and weather patterns would be the same on top as on the bottom. But there are some...
