Why graphene hasn’t taken over the world…yet

Graphene is a form of carbon that could bring us bulletproof armor and space elevators, improve medicine, and make the internet run faster — some day. For the past 15 years, consumers have been hearing about this wonder material and all the ways it could change everything. Is it really almost here, or is it…

Digging precious metals out of your old phone

Digging precious metals out of your old phone

E-waste is more than phones and laptops. There’s gold, silver, copper, and lots of other precious metals powering your electronics, and that makes for some valuable “e-waste”. And a recent study proposed that it’s now more cost-effective to dig minerals out of old electronics than out of the Earth. We crack open some old tech…

How this 50-year-old NASA invention could kill cancer

How this 50-year-old NASA invention could kill cancer

Ferrofluid is a bizarre, NASA-engineered material that was created for spaceships but never used. In this “lab practical” video, we’ll put ferrofluid through its paces, and explore some of the even stranger places it may yet be useful. Wanna know how we shot this video? Here’s the behind the scenes in 4K: https://www.youtube.com/watch?v=rdq-koNZlXk Subscribe: http://bit.ly/2FqJZMl…

Decoding cheese with DNA sequencing

Decoding cheese with DNA sequencing

Cheese is delicious, beloved by many, and a teeming mess of microbes. Which microbes, exactly, has long been a mystery, but modern DNA sequencing tech is allowing researchers to take a peek behind the microscopic curtain. We visit a professional cheese cave, test (and taste) some cheddar, and wait a year for microbial magic to…

What self-driving cars can learn from brainless slime mold

What self-driving cars can learn from brainless slime mold

Slime mold is a single-celled bit of goo that you’d find under a log in the woods. It’s also a master decision-maker, capable of weighing risk and reward in ways that make scientists question what intelligence really is. We grew slime mold of our own, and watched it tackle some amazingly complicated problems that could…
