Before there was Google, there were encyclopedias. The very idea of these vasat collections of knowledge can be credited to Pliny The Elder. So who was he, and why does he seem to pop up everywhere from Alchemy to Zoology? Hank Green has the story in this edition of SciShow: Great Minds.

Hank talks about the origins of four of these: the cell phone, the submarine, the telemanipulator (or robot arm), and the taser. Blast off for knowledge!

You’ve probably heard about the sudden and mysterious drop in honey bee populations throughout the U.S.A. and Europe. Beekeepers used to report average losses in their worker bees of about 5-10% a year, but starting around 2006, that rate jumped to about 30%. Today, many large beekeeping operations are reporting that up to 40 or 50 percent of their swarms have mysteriously disappeared. This massive die-off of honey bee populations has been dubbed colony collapse disorder, and it is a big, big deal. Find out more in today’s episode of SciShow with Hank Green.

We have the technology! We can rebuild…ourselves!
Human interface technologies like Google Glass, robotic prosthetics, and bionic eyes have the potential to help people recover lost abilities, but also to grant us new abilities. Will you someday be able to turn on your super-human hearing just by thinking about it? Maybe…if you live long enough. The question of whether we /should/ well, we’ll leave that to the philosophers. Hank Green reports on SciShow.

You’re probably aware of lots of the things we take from animals, but for centuries, humans have been sneaking animal secretions into a bunch of things you probably didn’t know about, like your Easter candy, your Mom’s perfume, and even that cigarette you probably shouldn’t be smoking. We also continue to enjoy delicacies that are only made possible because they come out of some animals’ mouths, glands, and butts. Hank Green explains.

Salvia divinorum, despite sounding like a spell from the world of Harry Potter, can’t turn you into an inanimate object, make you leave your body, or set your feet on fire. But it can make you FEEL like all of those things are happening. This little plant is a hallucinogen – one so powerful and unique that the DEA isn’t quite sure how to regulate it. Hank Green’s got the details on this psychotropic member of the sage genus in this episode of SciShow.
