Hello, and welcome to the kitchen. I wanted to invite you here today because last week we started off in my bathroom and kinda feel bad about that. And also because as I’m making lunch today I wanted to sort of use it as a lab. During this time in
In March of 2015, American astronaut Scott Kelly and his Russian colleague Mikhail Kornienko, began an unprecedented mission in space. They began a one-year term of service aboard the International Space Station, the longest tour of duty ever served on the ISS. Now, I imagine there’s all sorts of stuff
This is an animal. This is also an animal. Animal. Animal. Animal carcass. Animal. Animal. Animal carcass again. Animal. The thing that all of these other things have in common is that they’re made out of the same basic building block: the animal cell. Animals are made up of your
We’ve been spending a lot of time lately talking about eating, and digesting, and metabolizing food. And those are some of my favorite things in the world! It’s been a really great time. But, as with all good parties, or brunch buffets, in the end, we’re left with a mess.

It is time! We have arrived at the final conflict. The battle royale. A fight to the…well, hopefully not death, but a big fight anyway. It only seems fitting that we spend this, our last episode of anatomy and physiology, talking about one of your body’s last-ditch efforts to defend
No matter what you’re a fan of, you can probably think of two characters who fit the description. Holmes and Watson. Brennan and Booth. Kirk and Spock. Ron and Hermione. They’re close. They understand each other in ways that others don’t, and you really can’t picture one without the other.
Take a good long look at this — we’re gonna mess with your brain. This is the first stage of an optical illusion. Many illusions use patterns of light or perspective to exploit the disconnect that exists between sensation and perception — between what your eyes see and what your
