You'd think that the Northern and Southern Hemispheres would be basically symmetrical -- that since our planet is a ball, the climate, temperature, and weather patterns would be the same on top as on the bottom. But there are some...

Atomic clocks are the best timekeepers humanity's got these days, but scientists are working toward something even better: a SUB-atomic (aka nuclear) clock.

Deep in a Sardinian mine, researchers are constructing an experiment that hopes to solve what's known as The Worst Prediction In The History of Physics, and pin down the true identity of dark energy.

This video is about Bell's Spaceship Paradox of Special Relativity, wherein a pair of rockets (or spacecraft) connected by a weak thread accelerate with uniform acceleration, maintaining the same separation, and the question is: does the...

This video is about the physics of geosynchronous and geostationary orbits, why they exist, when they don't, when they're useful for communication/satellite TV, etc.

This week, a group of researchers use nuclear fallout to figure out how old liver cells are, while another gets one step closer to predicting volcanic eruptions.

Bones, you probably have them and they're for more than holding your body upright.

If salty water is constantly spilling into the world’s oceans, does that mean they are getting saltier by the day?

Carbon dating transformed fields like archeology and paleontology, but its use might be in danger.

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...

We all have that coworker who insists that the houseplants on their desks are improving the office air quality, but is there any truth to that? Hosted by: Olivia Gordon

When birds and squirrels cache food for the winter, it means they have to remember where to find that food later. Their strategies for finding their hidden feasts includes memory tricks and changing brains.

What could be cooler than a permanent lava lake surrounded by snow!?
