It’s Okay To Fart

Farting is hilarious and gross and everyone is doing it so why can’t we talk about the science of it?! Flatulence, passing gas, cutting the cheese, toots… whatever you call it, it’s natural. Humans pass gas about 20 times a day on average, and collectively, we fart about 7 billion liters of gas each day! Here’s how it works. Farts are either the result of trapped, swallowed air being expelled from the body, or as byproducts of the microbes living in your gut. In this episode of It’s Okay to Be Smart,…

Neoteny: Why Disney Princesses Look Like Babies

Neoteny, Evolution, and Disney Our friend Dr. Joe Hanson from It’s Okay to Be Smart (PBS Digital Studios) goes full science nerd on neoteny, Disney princesses, and evolution. I noticed something weird about Disney Princesses lately. Naturally, I had to examine it through the lens of science. The answer led me to new knowledge about human development, the domestication and taming of animals, and why we find things cute in the first place. You’ll never look at cartoons the same way again. –Joe Hanson, PhD Twitter: @DrJoeHanson @okaytobesmart Instagram: @DrJoeHanson…

Cooking, Evolution, and Brain Growth

Cooking establishes the difference between animals and people. In fact, we’re not the only social animals that sit down to eat together, but we are the only ones who cook. But how is cooking linked to human brain’s growth and evolution? This is a video from Dr. Joe Hanson’s It’s Okay To Be Smart series. Cooking helped humans strengthen social bonds and cooperation. Although our brain uses one-fifth of the calories that we eat, we spend only 5 percent of our daily lives eating, while Chimpanzees and Gorillas spend more than half…

7 Scientific Urban Legends Debunked

How reliable is common knowledge? If a large number of people believe something, that doesn’t make it true. Dr. Joe Hanson of the It’s OK to Be Smart series from PBS Digital Studios debunks 7 scientific urban legends. He also makes a compelling argument for why we desperately need open-access science information and effective communication. Sometimes common knowledge is wrong. For common knowledge to be right, then knowledge needs to be, well, common. It sounds like such an incredible fact. “Our own cells are outnumbered by our microbes 10 to…

How to Drink Coffee in Space

Many of us remember being in a school assembly when an astronaut came to speak. The question on every kid’s mind (and teacher’s mind too, let’s be honest) was, “How do you go to the bathroom in space?” But what about other important things involving liquids in space? As it happens, there is a lot of research surrounding the behavior of fluids in zero gravity, such as how to drink coffee in space. In this video, our friend Dr. Joe Hanson from It’s OK to Be Smart explains why this…

Laugh: Marc Kjerland Biology Videos 

Why Do We Laugh?

Laughing is a universal human behavior, one that transcends borders of language and culture. But it’s also REALLY WEIRD. Why do we do it? The answer has less to do with humor than you might think, and more to do withs socializing, bonding, and biology. Laugh Hard, Laugh Often This video from It’s OK to Be Smart and PBS Digital Studios is written and hosted by Dr. Joe Hanson, Ph.D. Special thanks to Dr. Joe for granting permission to publish his videos on GotScience.org.

So I went behind the scenes at the Monterey Bay Aquarium with my new friend Tommy to learn all about them. I saw some things…” Dr. Joe says. Enjoy!

Proof of Evolution Is in Your DNA

Another great video from our friend Dr. Joe Hanson and the team at It’s Okay to Be Smart, brought to you by PBS Digital Studios. This time, we’re looking at the proof of evolution that’s embedded right there in our DNA. Humans are special, and we got that way thanks to evolution and natural selection. The proof is right there in our bodies! From anatomy to genes, here are some stories of how you got to be the way you are. Dr. Joe Hanson, It’s Okay to Be Smart References…
