How To: Understand saltatory conduction in neurons

This video is a discourse about saltatory conduction in the neurons. According to the author, it begins with the opening of a gate on the membrane of one of the dendrites of a neuron, and positive charge enters through this gate. The positive charge spreads throughout the cell, and gets dissipated as it spreads, so that, by the time it reaches the Axon hillock of the neuron, it is left with very little potential. However, the potential which results from the simultaneous excitement of many de...

How to Make Ferrofluid: The Liquid of the Future

What Is Ferrofluid? Ferrofluid is a black, solvent-based liquid, that, in the presence of a magnetic field, becomes strongly magnetized. The fluid is made up of nanomagnetic particles coated with an "anti-stick" or surfactant compound, suspended in a "carrier", commonly an organic solvent. For mechanical applications, it is used in hard drives and speakers as a lubricant. However, it also has been implemented in artwork, as seen in the video below.
