A Birds-eye View

After years of research, scientists are finally beginning to understand the meaning of birds-eye view. While humans have three color receptor cells, or cones, in our eyes to detect red, blue and green, birds are blessed with four. SciShow’s Hank Green tells us that birds not only can see the Earth’s magnetic field but also ultraviolet light, and throws in a few more amazing facts about our fine feathered friends.

Predict the Odds of Anything

Statistics are every scientist’s best friend. But the numbers aren’t always easy to interpret. In this edition of SciShow, host Hank Green explains why the methodology of Bayesian Reasoning can lead to some surprising conclusions.

A Black Hole Conundrum

Mega-scientist Stephen Hawking threw his colleagues for a loop recently, when they thought he wrote in a paper that black holes do not exist. Hank Green, of SciShow, says those who read the paper apparently took the TLTR (or too long to read) route, instead assuming there was some major breakthrough or breakdown in astrophysics. Green takes the time to put Hawking’s thoughts into context.

The Potential Of Magma Power

With the constant debate over which sources of energy our country should harness, Hank Green, of SciShow, has a valid suggestion. Why not volcanic power? “One of the most massively powerful forces we have here on Earth, a store of energy so gigantic that it liquifies trillions upon trillions of tons of rock, and  is independent from the sun’s energy output. It’s the pressure of the Earth pushing down on itself, heating its interior to such dramatic temperatures that every once in a while a pimple (volcano) will erupt on its surface, spewing rock kilometers into the air. If only we could capture that energy.”

Celibacy Bugs Some Insects

Hank Green tackles three freaky things attributed to nature, including the polar vortex that gripped the country last week, the oddity of bug sex and the phenomenon of how a chain defies gravity. Green gives us the details in this version of SciShow.

Sweet On Chocolate

Many of us crave it. Some of us just can’t do without. It’s safe to say that chocolate has captured our taste buds and imaginations. But what is it about this irresistible confection that drives us to the point of addiction? Hank Green explains in this edition of SciShow.

2013′s Greatest Discoveries

2013 was the year of three incredible discoveries in the fields of physics, space science and anthropology. Hank Green lays out the details in this edition of SciShow.

Ancient Mars Was Habitable

Curiosity, the nuclear-powered rover on the surface of Mars, has uncovered evidence in the giant Gale Crater of ancient life on the Red Planet. SciShow’s Hank Green discusses the mounting evidence that ancient Mars was habitable over larger areas and longer periods of time than we ever thought.

Top 5 Deadliest Substances

The most lethal toxin known to man is produced by the tiny bacterium clostridium botulinum, more commonly known by the disease it causes–botulism. The toxin is so potent that it would only take a crystal of botulinum the size of a grain of sand to kill 9,600 people. Join Hank Green in this edition of SciShow, as he discusses how botulinum and four other deadly poisons attack the human body.

Simply Irreplaceable

Scientists recently released a list of the most biologically important locations on the planet, surprisingly coming up with 137 of them. In this edition of “SciShow,” Hank Green takes you on a tour of four of these gems, elaborating on why they are simply irreplaceable.
