There’s a connective tissue running all throughout your body that not only holds all your muscles and organs together, but also has sensory and mechanical properties that may explain some poorly understood medical phenomena.

You probably know about the geomagnetic field that protects the earth from solar storms and radiation. But precision satellites have measured ANOTHER magnetic field coming from Earth, and its signals might hold the key to searching for...

Neuroscientist Greg Gage takes sophisticated equipment used to study the brain out of graduate-level labs and brings them to middle- and high-school classrooms (and, sometimes, to the TED stage.) Prepare to be amazed as he hooks up the...

There are 600 million women in India -- yet they are rarely seen outdoors after sunset because of safety concerns like harassment and catcalls. On a mission to create safer public spaces, women's rights advocate Srishti Bakshi talks...

We continue our look at your bones and skeletal system, skipping over the silly kid's song in favor of a more detailed look at your your axial and appendicular skeleton. This episode also talks about the structural and functional...

In this video Paul Andersen explains how the energy of a wave if directly related to the amplitude of a wave. The wave energy of a sound wave is the volume of the wave.

Peering into the eyes of different animals, you'll see some extraordinarily shaped pupils. House cats, for one, are twilight hunters with vertically elongated pupils. Many grazing animals, like goats, have rectangular pupils. Other...

In this video Paul Andersen explains how classical waves (like light) can have particle properties. Albert Einsetein used the photoelectric effect to show how photons have particle properties.

Flying is a great way to get around, but humans have only been doing it for a little over a century. Let’s revisit six SciShow videos exploring the world of flying non-human animals, which includes some species that you might not expect!

We know more about some other planets than we do about the deepest corners of Earth's oceans, and the species we've found there are almost alien. Here's some of the most unbelievable oddities ever observed! Special thanks to the Monterey...

In this video Paul Andersen explains how the average value of the electric field can be determined by dividing the potential difference by the displacement. Equipotential lines can be used to determine the potential in an electric field...

In this video Paul Andersen explains how the wave speed measure the speed of a wave through a medium. The medium determines the speed of the wave. The velocity of the wave is equal to the product of the wavelength and the frequency of...
