Debunking Brain Myths

Personality tests tell us that left-brained people are steeped in logic and blessed with strong math and science skills, while right-brainers are more creative and adept at the arts. But it seems that a Nobel-winning research study in the early 1960s turned into a misunderstanding of how we characterized these people over the decades. Host Hank Green unravels the myth and seeks the truth in this edition of Scishow.

Science Can Be Crazy

It seems some of the scientific discoveries that have dramatically changed our lives over the years still remain mysteries. Take the disappearance of ancient Europeans. Scientists recently analyzed 37 skeletons discovered in Central Europe and dating between 7,500 and 2,500 years ago, revealing that the genetic lineage was transformed approximately 4,500 years ago. More study showed that these ancestors had dark skin and light eyes, but researches are still unable to pinpoint what caused these radical changes. Learn more about nine other crazy discoveries that science can’t explain in this edition of Hybrid Librarian.

Your Brain On Extreme Weather

Extreme weather, snowmaggedon and polar vortex are terms that have dominated your local weather channels. But Minute Earth tells us that rain or shine, our minds tend to prize their freshest impressions. “Even when we experience the same weird weather events as other people, we don’t always agree on how weird they were,” says host Emily Elert. Even politics plays a major role.

White Holes Rare But Possible

Black holes, where gravity becomes so intense that it overwhelms everything, are major forces in our universe. White holes, on the other hand, could be described as black holes in reverse, a virtual impossibility. But SciShow’s Reid Reimers says science has revealed that they are technically possible and, “We might have seen one.”

Man’s Best Friend a Mystery

There isn’t a lot known about how and when dogs were domesticated. But we do know that the process made them very different from their wild cousins, including three really weird things that are explained in this edition of SciShow.

Why We Haven’t Met Aliens

One of mankind’s biggest questions is, “Are we alone in the universe?” Scientists still haven’t solved the mystery, but we’re getting oh-so close. This edition of Hybrid Librarian studies 10 intelligent reasons why we haven’t been in contact with ay aliens. Among them is the chance that another civilization similar to ours is too far away to catch a glimse of modern Earth. In other words, if an alien astronomer 65 million light years away looked through a telescope, he’d see dinosaurs from the Cretaceous Period because of the time it would take light to reach his eyes. They’d have no clue that humans inhabited Earth.

The Same Old Moon

It’s safe to say our relationship with the moon is pretty one-sided–literally. Because it rotates exactly once on its axis each time it orbits Earth, we always see the same old side of the moon. Fact is, the first time we saw the far side of the moon was when Russian satellite Luna III beamed back images in 1959. Join Henry Reich as he discusses the moon’s evolution and how it settled into its current orbit in this edition of Minute Earth.

How Measles Returned

Wasn’t measles eradicated in the United States years ago? Well, it’s baaack! But how? Hank Green says the disease has been back for about two months and the Center for Disease Controls says it could gain a foothold unless we get vaccinated. The current strain, Green says, comes from the Phillipines and might well threaten an endemic in our country. Tune in to this edition of SciShow as Green explains the unlikely comeback of the disease.

Did the Past Really Happen?

Did the past really happen, or did it all begin last Thursday? Michael Stevens calls the theory “Last Thursdayism,” and it questions everything that’s happened on our planet. In this unusual edition of Vsauce, Stevens explores how future inhabitants of Earth will remember us.

The Worst Nobel Prize Awarded

Portuguese neurologist Antonio Egas Moniz developed a surgical procedure that was successful in advancing mental health, according to his peers. Although adopted by neuro-scientists, surgeons and scientists around the world, it was at its best irreversibly destructive and at its worst inhumane. “And yet, Moniz was awarded the Nobel Prize in Medicine for it,” says SciShow host Michael Aranda. “It’s quite possibly the most regrettable Nobel Prize ever awarded, because Moniz was given the prize for developing lobotomy.” Tune in as Aranda digs into the details.
