Today, some companies are working hard to prevent consumers from repairing products on their own. In many cases, repair can only be done by the original manufacturer, if at all. With limited repair options available, we end up buying new...

Have you ever wondered why 75% humidity in the summer feels sticky, but 75% humidity in the winter feels super dry? Turns out, the common definition of humidity is inconvenient and confusing. But there is a better way!

It's no secret that cold can help treat a source of pain, like a sprained ankle or even a burn. But new technology might be able to take that principle and apply it /directly/ onto your nerves!

No one likes being sick, but can you imagine catching a bug while hurling through space? Turns out, this is an issue that many space agencies have worked to study and mitigate. <b<br/>r/>

Bad ideas come and go in physics. But there’s one bit of nonsense that is perhaps more persistent than all others: the perpetual motion machine. No working perpetual motion machine has ever been experiment verified. All break the laws of...

In 2015, two men drove a Volkswagen across the US on just over 100 gallons of fuel. Their 81-mile-per-gallon performance doubled the car's estimated fuel rating, and set the record for the lowest fuel consumption ride of a diesel car....

Have you ever wondered why 75% humidity in the summer feels sticky, but 75% humidity in the winter feels super dry? Turns out, the common definition of humidity is inconvenient and confusing. But there is a better way!

Scientists have been trying to pull blood out of the body and put it back in again since the early 1800s, but bypass machines haven't been easy to get right.

Improving batteries is a tough problem, but it’s also an important one because in many ways the future of our planet also depends on the future of batteries. Luckily, scientists are on the case, figuring out ways to give this essential...

Hank talks about how warp drives could potentially work.

In this exclusive preview of groundbreaking, unreleased technology, former Apple designer and Humane cofounder Imran Chaudhri envisions a future where AI enables our devices to "disappear." He gives a sneak peek of his company's new...

Medieval Europe. Where unbathed, sword-wielding knights ate rotten meat, thought the Earth was flat, defended chastity-belt wearing maidens, and tortured their foes with grisly gadgets. Except... this is more fiction than fact. So, where...

There are about 450 million diabetics around the world, and while we do already have a reliable way of measuring blood sugar, it requires patients to prick their finger each time they want a reading. Is there a better way?

Daniel Kraft offers a fast-paced look at the next few years of innovations in medicine, powered by new tools, tests and apps that bring diagnostic information right to the patient's bedside.

Scientists have found some effective alternative treatments for patients with treatment-resistant depression, but they are not exactly sure why these treatments work.

A team is encoding digital data into DNA molecules which are then embedded into larger physical objects, like this plastic bunny! And researchers are working on a new, low maintenance oral contraceptive.

In this video Paul Andersen explains how inertial mass is defined and measured. When a force is applied to an object or a system it will accelerate. Using Newton's Second Law of Motion (F=ma) you can calculate the inertial mass.

Where science fiction becomes science fact - that is the place Hank is exploring in today's episode of SciShow. Many inventions we use today were first imagined in stories that described fantastical futures. Hank talks...

From the sharp mouthparts of mosquitoes to the sticky feet of geckos, researchers have found all kinds of amazing adaptations in the natural world that could be useful in the operating room.

Perpetual motion machines - devices that can do work indefinitely without any external energy source - have captured many inventors' imaginations because they could totally transform our relationship with energy. There's just one...

Chemist Lee Cronin is working on a 3D printer that, instead of objects, is able to print molecules. An exciting potential long-term application: printing your own medicine using chemical inks.

You're enjoying a nice simulated drive using your VR headset, when you're suddenly jolted with nausea. What is causing this gross feeling? Check out this episode to learn how sensory input and VR simulation can throw your body off.

It's moments after the Big Bang and you're still reeling. You're a particle of matter, amidst a chaotic stew of forces, fusion, and annihilation. If you're lucky and avoid being destroyed by antimatter, you'll be the seed of a future...
