Seasonal illnesses from infectious diseases aren’t a new concept, but a few decades ago public health experts began to notice the same behavior in some non-infectious diseases like breast cancer. These patterns have helped us learn a lot...

The story of the word X-Ray is one of great thinkers. French philosopher Rene Descartes isolated the letters X, Y and Z to stand for unknowns, and centuries later, Wilhelm Rontgen discovered the X-ray, using the X for the unknown nature...

Diamonds are iconic, but some of them might make others a little green with envy.

Radiation sickness been portrayed in movies and television for more than 50 years. And those portrayals vary a lot. But if there’s one thing pretty much all these portrayals have in common, it’s that they get radiation sickness wrong—at...

In this video Paul Andersen attempts to explain the age old questions - What is Energy? Even though it comes in many forms one of the defining characteristics of energy is that it is conserved over time. He then explains that all...

Can the radiation emitted by electronic devices affect your body and make you feel terrible?

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...

You might expect to find these fish at the core of an ancient, distant asteroid, but we find them instead on Earth. That doesn’t mean they aren’t special, though. In fact, their immune systems may be the key to unlocking a new treatment...

You can't open up a magazine without seeing someone with impossibly smooth skin selling some sort of "anti-aging" cream, but could some of these products actually work?

According to the cosmological principle, the universe is more or less the same in all directions. But what happens when we put this to the test?

Genomics pioneer Craig Venter takes a break from his epic round-the-world expedition to talk about the millions of genes his team has discovered so far in its quest to map the ocean's biodiversity.

Billions of galaxies, each with billions of stars, each with .... rather a lot of particles in them. And then there's dark matter, black holes, planets, and the particles and radiation in between the stars and galaxies. But.... is the...

We only know 4% of what the universe is made up of. Can we also know what lies beyond our galaxy ... and if there are undiscovered forms of matter? Luckily, we have space messengers - cosmic rays - that bring us physical data from parts...

Solar Storms! Moaning Myrtle! Wondering what the frick is behind the solar flares that slammed Earth earlier this week? Hank lays out how that juicy ball of plasma we call the sun causes us trouble from time to time.

In this week's news, Hank explains how earthworms are doing nanotechnology for us, Americans will soon be eating genetically modified salmon, the Russians are going back to space, and another reason to drink less soda.

Hank answers a SciShow viewer's most pressing question about what happens if the human body gets exposed to space. Would your head really explode?

Last week, NASA released some pretty cool Mars news: Curiosity found even more evidence to indicate the planet could’ve been habitable billions of years ago.

You might think we've already found every kind of star by now, but astronomers think there are more that should hypothetically exist!

There is a chemical reaction discovered a century ago that could be the key to creating everything from fuel to shelter on Mars!

Nuclear weapons are the most destructive things we’ve ever created, but it turns out there’s a way to make them even deadlier…

Jimmy Lin is developing technologies to catch cancer months to years before current methods. He shares a breakthrough technique that looks for small signals of cancer's presence via a simple blood test, detecting the recurrence of some...
