Evolving into the Future

The rapid advancement of technology will play a large role on how we evolve as human beings. For instance, our future relatives will more than likely have eyes that become unnervingly larger and blink sideways to avoid cosmic rays. They will also grow as we colonize alien planets in dimmer environments. Discover nine more evolutions to the human race in this edition of Alltime 10s.

Baby It’s Hot Down There

Lord William Thompson Kelvin, of absolute temperature fame, attempted and failed to determine why the heat of the Earth increased exponentially the deeper you descended. He theorized that Earth actually started off hot and had been cooling off ever since. Unfortunately for Kelvin, he failed to factor in radioactivity in the Earth’s core. In this edition of Minute Earth, Emily Elert digs deeply into what really keeps the Earth’s core toasty.

The Science of Sleep

Not surprisingly, one of the world’s most searched questions on Google is, “How can I fall asleep.” And that includes includes queries from 60 million Americans. Michael Aranda gets us some answers in this educational edition of SciShow.

Terms Of Disendearment

Familiar with the terms “psycho, ocd, schizo, bipolar?” They’re terms we’ve recklessly used to insult someone, not really understanding their true definitions. Health professional say using such words minimizes serious conditions and the people who have them. In this edition of SciShow, Hank Green sets the record straight on what these words mean and tells us why it’s not cool to say the weather is schizophrenic.

Peeking Into the Future

With the accelerating rate of technology advance in medicine, prepare to double your life expectancy in the future. In the last 50 years alone, life expectancy has risen from 65 to 75. But science will soon unveil nano robots that will travel through your bloodstream and fix anything, boosting your life expectancy to more than 100 years old. Danger Dolan takes a look at 14 other seemingly miraculous advances in technology that will blow your mind.

The Sky is Not Really Blue

Shockingly, the sky is not blue and the sun isn’t yellow. “The sky is not really blue,” says Henry Reich of Minute Physics. “It’s a stage upon which all colors dance. It’s mostly transparent air that, at best, is the color of what light it scatters.” Tune in as Reich explains the grand ballet of light in our universe.

Virus Strain a Worthy Foe

The mysterious Enterovirus that has enveloped the country is posing major problems for the U.S., especially for our children. A particular strain of the virus, D68, is a worthy adversary. In this edition of SciShow, Hank Green explains the science of the latest virus to break out in the U.S. (Update: Sadly, since this video was shot, there have been two confirmed deaths due to the virus, both children ages 21 months and 4.) Also in this edition of SciShow, Green examines the planet’s looming population boom, which is expected to reach between 9.6 and 12.3 billion people.

What Really Killed T-Rex?

True, a mega-asteroid was responsible for wiping out the dinosaurs 66 million years ago. But is there more to the story? SciShow’s Hank Green discusses evidence that suggests there were other factors percolating that turned a really bad day into one of the worst days in the history of the planet.

Size Isn’t Everything

Astronomers at Georgia State University say they have discovered what may well be the smallest star in the universe. The star is 8.6 percent as wide as the our star, the sun, 8,000 times dimmer and can actually fit inside the planet Jupiter. Phil Plait of badastronomy.com explains how astronomers determined the star’s status, including mistaking it for a brown dwarf in the early stages of their research, in this edition of SciShow Space.

Ebola Virus Wreaking Havoc

Ebola is one of the world’s deadliest diseases that is wreaking havoc throughout West Africa and threatens to spread beyond the continent’s borders. SciShow’s Hank Green delves deeper into the disease, especially the Zebov (Zaire Ebola Virus) strain, which has infected 1,323 people this year, 729 of whom have died.
