There’s an oft-repeated story among school children that if you managed to keep your eyeballs open while sneezing, that they’d pop right out of their sockets. SciShow digs into this little gem to see if there’s any reason to actually be worried the next time you let out an atchoo.
(PG-13: Language) When you think of it, the skeletons of all creatures are a little weird looking, but some are definitely weirder than others. Tune in to this lesson from the Sam O’Nella Academy and enjoy 10 of the worst bone designs that mother nature has bestowed upon the world.
You might think that mammals always ate meat, but it turns out it was an evolutionary necessity due to changes in Earth’s climate. Kurzgesagt explores whether or not this change in our diets was actually good for us, or if eating meat truly has a negative impact on our health.
We wouldn’t be here on this planet if it weren’t for evolution – and a big part of the evolutionary process is natural selection. Primer presents a great 10 minute lesson on how the whole “survival of the fittest” thing works, along with a visual simulation with little blobby creatures.
The human body is an amazing organic machine that performs countless tasks every minute of every day. In this video from The Infographics Show, they tally up some of the things that your body will do in the next minute – or twice as much while you watch the entire 2 minute clip.
Kurzgesagt wraps up 2017 with a follow up to its fascinating clip about the relationship between an organism’s size and the way it evolves. This time out, we learn how we might actually explode if we weren’t the size we were meant to be. Say, was that Barb at 1:30?

We’re sure that we’re oversimplifying in our headline, but we’ll let TED-Ed and molecular biologist Anusuya Willis explain how the single-celled cyanobacteria which nearly wiped out most life on Earth, then gave us the oxygen and plants we all need to exist.
