This week's SciShow news has Hank bringing us a primer on the science behind various illegal and illicit ways in which athletes "improve" their bodies, proof of general relativity that we can actually see, and a new way to measure how...

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...

Snorkelers, surfers, divers. They all use them… wetsuits! So how do they work to keep you warm? It turns out layers of materials, and water itself!

While viruses can be deadly and completely wreak havoc on humanity, they can also sometimes change our world for the better. Join Hank Green for a new episode of SciShow and learn the truth about the viruses that have shaped humanity...

Ever wondered what our buildings might look like in the future? Right now, the construction industry heavily relies on concrete, but it isn't great for the earth. Join Hank Green for a new episode of SciShow and take a look at what the...

Gems are more than just pretty rocks! Hosted by: Michael Aranda

If we're going to solve the climate crisis, we need to talk about construction. The four main building materials that humans currently use -- concrete, steel, masonry and wood -- have a heavy environmental impact, but what if we had a...

Squeaks is back from visiting Sam the Bat’s cave and is excited to learn all about how different caves form and why they look the ways they do!

To restrain global warming, we know we need to drastically reduce pollution. The very next step after that: using both natural and technological solutions to trap as much excess carbon dioxide from the air as possible. Enter Orca, the...

In 1967, James Bedford had a plan to cheat death. He was the first person to be cryogenically frozen. This process promised to preserve his body until a theoretical future when humanity could cure any illness, and essentially, reverse...

Book: Partners in Power: Nixon and Kissinger

In the 70 years that plastic has been around, humans have created 9 billion tons of it -- most of which still exists. Are the existing strategies for tackling plastic pollution -- namely reusing and recycling -- really making any...

Paul Andersen (with the help of PatricJMT) explains why mathematics may be biology's next microscope.

Black holes are the result of absolute gravitational collapse of a massive body: a point of hypothetical infinite density surrounded by an event horizon. At that horizon time is frozen and the fabric of space itself cascades inwards at...

Paul Andersen emphasizes the importance of cooperation in living systems. He starts with a brief description of game theory and why countries at peace do better over the long term. He then explains how microscopic cells cooperate in...

Concrete is the second most-used substance on Earth (behind water), and it's responsible for eight percent of the world's carbon footprint. Cement researcher Karen Scrivener shares the research behind a pioneering new kind of cement...

This Nobel Prize season, dive into the world of the super small for physics and chemistry. It's where the nanocars roam and phase transitions get really weird.

Hank brings us another simple experiment that demonstrates the important biochemical process of osmosis by turning a chicken egg into a frightening alien-looking thing.

European researchers claim to have developed a composite material that is basically uncuttable, so with this material, your bike might never be stolen.

Astronomers have thought for years that Earth was dry in the beginning, but a new paper suggests that Earth might have actually started out wet! And In other meteorite news, a new study of impact sites might give us new clues about...

This video is about using particle accelerators as part of the solar panel silicon wafer manufacturing process. The accelerators embed protons into the wafer crystals, allowing them to break and separate from the main crystal in...

As we look towards longer missions to the Moon, the shear amount of resources needed to survive becomes a much bigger question. Without space semi-trucks to haul life-giving resources to astronauts, can we utilize the Moon’s barren...

Researchers created a "super jelly" that can survive being run over with a car, and its weird properties take advantage of some novel chemistry.

Scientists are always searching for new materials that maximize strength and thermal protection while also minimizing mass for space flight. So, when developing new heat shields, why are they looking to cuttlefish for inspiration?
