The Evolution of Music

Popular music has evolved in the last 50 years in ways that would make Darwin proud. To document the evolution of popular music, researchers from both the biology and music genres analyzed the songs on the Hot Billboard 100 from 1960 to 2010. Their theory was that like life, culture evolves. Host Michael Aranda divulges the surprising results of the study and also takes a look at how sleep-walking and sleep terrors are genetically linked in this edition of SciShow.

Rain’s Dirty Little Secret

A touch of salt, a speck of soot, a grain of clay. Believe it or not, microscopic portions of one of these is present in every drop of rain. And they are also absolutely crucial to the existence of rain. Without these small pieces of dirt, there would be no rain at all.. Join Emily Elert in this edition of Minute Earth.

Allergies the Bane of Spring

It’s estimated that 40 percent of the world’s population suffers from allergies. Translation: Once spring has sprung, look out for watery eyes, sneezing and trouble breathing. Host Michael Silva educates us on allergies and their causes, and whether they can be prevented in this edition of SciShow.

Homes Away From Home

Nearly 2,000 alien planets have been discovered in our solar system since 1995, and scientists believe at least 10 of them could host life. Hybrid Librarian presents a countdown of the most favorable candidates to welcome mankind and life.

Planets Beyond Neptune

Science tells us there are only eight planets in our solar system. But will advanced technology and improved telescopes prove us wrong? “According to at least two teams of researchers, there might be a few planet-sized worlds lurking out beyond Neptune,” says host Hank Green. Some scientists theorize there is a planet at least 10 times the size of Earth out there quietly orbiting the sun. Green explains in this edition of SciShow.

How Airplanes Stay Airborne

Have you ever wondered how mega-ton airplanes stay airborne? A wonder of science, for sure. But more precisely, it’s a byproduct of Newton’s Laws of Physics. “Airplanes stay in the air because of one simple fact,” says Henry Reich. “There is no net force on them. And with no net force, an object at rest stays at rest and an object in motion stays that way.” Join Reich in this edition of Minute Physics as he explains the phenomenon.

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.”
