Hank describes some of the best explanations that neurologists have come up with to account for the strange sensation we know as déjà vu.

Hank talks about why it is so difficult for scientists to predict earthquakes in the short term.

GPS devices aren't just for keeping you from driving into a lake. They're also helping lots of scientists in unexpected ways.

Did you know that nature contains clues that can uncover ancient earthquakes that occurred decades, or even centuries ago? Join us for a fascinating look into the world of ancient earthquakes, and see how yesterday's quakes compare to...

When Climate Change Threatens Climate Solutions | SciShow News

Pirate fishing, oil spills and other undetected crimes are destroying ocean ecosystems -- but we can't stop what we can't see. Harnessing the power of satellite data and AI to catch maritime offenders in the act, ocean conservation...

Nearly 40 percent of humanity lives near a coast -- and no two coasts are the same. How can these communities build resilience to the increasing risks of climate change? Climate advisor Dave Sivaprasad outlines how to tackle this complex...

Nestled in the forests of Canada sits the world's longest beaver dam. This 850-meter-long structure is large enough to be seen in satellite imagery and has dramatically transformed the region, creating a pond containing 70 million liters...

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...

For the next half of this series, we will be discussing Human Geography — so we’ll still be looking at the Earth, but specifically, how human activity affects and is influenced by the Earth. Naturally, we thought the best place to start...

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.

Why are we talking about dark energy again? Because another team has just announced a new analysis of updated supernova data. They claim that the data are consistent with there being NO dark energy - no accelerating expansion. They...

For the last 12 years, LaToya Ruby Frazier has photographed friends, neighbors and family in Braddock, Pennsylvania. But though the steel town has lately been hailed as a posterchild of "rustbelt revitalization," Frazier's pictures tell...

The climate crisis has been largely caused by irresponsible adults in developed countries, but it's the children of developing nations -- like Zimbabwean environmental activist Nkosilathi Nyathi -- that suffer from the most disastrous...

Alzheimer's disease is the most common cause of dementia, affecting over 40 million people worldwide. And though it was discovered over a century ago, scientists are still grappling for a cure. Ivan Seah Yu Jun describes how Alzheimer's...

Experiments conducted by Hilde Mangold and Hans Spemann taught us how an animal develops from a small ball of cells into an organism with distinct, functioning parts. The work was a foundational contribution to the field of developmental...

Iran and Israel: two nations with tense relations that seem existentially at odds. But for all their antagonistic rhetoric, there is a recent hidden history of collaboration, even friendship. In an informative talk, Trita Parsi shows how...

So, today we're talking about African Pantheons. Now, you might say, that's ridiculous. Africa isn't a single place with a single pantheon, and we'd be fools to try and cover all that in an eleven minute video. You'd be right. Instead...

Why does the universe seem to be moving in one particular direction?

Beginning in the third century BCE, the Romans conquered the Iberian peninsula. This period gave rise to several regional languages in the area that's now Spain, including Castilian, Catalan, and Galician. One of these would become...

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...

Usually, you can count on a river to flow in one direction, but some things can make it reverse course. Aside from being weird and surprising, these river reversals can often reflect geological changes and have long-lasting impacts on...

Drugs alone can't stop disease in sub-Saharan Africa: We need diagnostic tools to match. TED Senior Fellow Frederick Balagadde shows how we can multiply the power and availability of an unwieldy, expensive diagnostic lab -- by...

An atom smasher, or particle accelerator, collides atomic nuclei together at extremely high energies, using engineering that exploits incredibly cold temperatures, very low air pressure, and hyperbolically fast speeds. Don Lincoln...
