Why Is The Universe So Empty? (ft. PHD Comics!)

Adults Science
Why is the universe organized the way it is? And why is it so empty? From planets and stars to superclusters and galactic filaments, the universe's largest structures formed because of its smallest. In this special collaboration with PHD Comics, we'll learn how the earliest, quantumest blips seeded the structure of everything everywhere.

Is DNA the future of data storage? - Leo Bear-McGuinness

Adults Science
In the event of a nuclear fallout, every piece of digital and written information could all be lost. Luckily, there is a way that all of human history could be recorded and safely stored beyond the civilization's end. And the key ingredient is inside all of us: our DNA. Leo Bear-McGuinness explains.

How aspirin was discovered - Krishna Sudhir

Adults Science
4000 years ago, the ancient Sumerians made a surprising discovery: if they scraped the bark off a particular kind of tree and ate it, their pain disappeared. Little did they know that what they'd found was destined to influence the future course of medicine. Krishna Sudhir traces the history of aspirin.

We Try To Eat Like Michael Phelps For A Day

Adults Science
Grits are better with syrup in them!

This New Pill Could Cure Peanut Allergies

Adults Science
A new study might've found a possible cure for peanut allergies. How does it work?

Why do we harvest horseshoe crab blood? - Elizabeth Cox

Adults Science
During the warmer months, especially at night during the full moon, horseshoe crabs emerge from the sea to spawn. Waiting for them are teams of lab workers, who capture the horseshoe crabs by the hundreds of thousands, take them to labs, harvest their cerulean blood, then return them to the sea. Why? Elizabeth Cox illuminates the incredible properties of horseshoe crab blood.

Are you a body with a mind or a mind with a body? - Maryam Alimardani

Adults Science
Our bodies - the physical, biological parts of us - and our minds - the thinking, conscious aspects - have a complicated, tangled relationship. Which one primarily defines you or your self? Are you a body with a mind or a mind with a body? Maryam Alimardani investigates.

Myths and Facts About Superintelligent AI

Adults Science
We live in an era of self driving cars, autonomous drones, deep learning algorithms, computers that beat humans at chess and go, and so on. So it's natural to ask, will artificial superintelligence replace humans, take our jobs, and destroy human civilization? Or will AI just become tools like regular computers. AI researcher Max Tegmark helps explain the myths and facts about superintelligence, the impending machine takeover, etc.

Is it possible to create a perfect vacuum? - Rolf Landua and Anais Rassat

Adults Science
The universe is bustling with matter and energy. Even in the vast, apparent emptiness of intergalactic space, there's one hydrogen atom per cubic meter. But is there such thing as a total absence of everything? Is it possible to make a completely empty space? Rolf Landua and Anais Rassat explain the science behind vacuums.

DNA Doesn't Look Like What You Think!

Adults Science
Biology textbooks are full of drawings of DNA, but none of those show what DNA actually looks like. Sure, they're good models for understanding how DNA works, but inside of real cells, it's a whole lot more interesting. Learn why we can't look directly at DNA, and find out how DNA is actually packed inside cells.

What Happens If We Bring the Sun to Earth?

Adults Science
What happens if we bring the sun to earth? No, seriously.

Will we ever be able to teleport? - Sajan Saini

Adults Science
Is teleportation possible? Could a baseball transform into something like a radio wave, travel through buildings, bounce around corners, and change back into a baseball? Oddly enough, thanks to quantum mechanics, the answer might actually be yes... sort of! Sajan Saini explains.

We're STILL Not Saying It's Aliens, But Tabby's Star Is Getting Weirder

Adults Science
The light from KIC 8462852 faded again, and scientists have some new theories about what's behind astronomy's most mysterious star.

You Might Get Fat Just By Smelling Your Food

Adults Science
The nose's olfactory receptors are stimulated when we smell food and other odors. But could the process of smelling cause weight gain?

Why It's HARD To Land on Mars

Adults Science
This video is about why it's harder to successfully land spacecraft and landers and rovers on Mars than on Earth, or Venus, or the Moon, or Titan, or asteroids. It all comes down to atmospheric density! When there's no atmosphere, you can do a powered descent in a flimsy tinfoil spacecraft like the Lunar Module, and when there's plenty of atmosphere you can do an unpowered descent via heat shield and parachutes like the space shuttle, Apollo command module, Soyuz, Huygens, etc. But on Mars with its thin air, you have to do both powered & unpowered descent, getting the worst of both worlds.

The snakey, viney robot that can go almost anywhere

Adults Science
Researchers at Stanford University developed a soft, squishy robot that "grows" like a vine and can squeeze through tight spaces. It can also lift heavy objects, which makes it potentially ideal for search-and-rescue operations.

The left brain vs. right brain myth - Elizabeth Waters

Adults Science
The human brain is visibly split into a left and right side. This structure has inspired one of the most pervasive ideas about the brain: that the left side controls logic and the right side controls creativity. And yet, this is a myth, unsupported by scientific evidence. So how did this idea come about, and what does it get wrong? Elizabeth Waters looks into this long held misconception.
