This is the ‘corpus callosum’ of a pig brain. This structure contains millions of neural fibres connecting the left and right hemispheres of the brain, allowing them to communicate. In humans it is reportedly larger in people who are ambidextrous. Watch the full brain dissection here: http://youtu.be/U5_kckcYiCc
By adding calcium carbide to ice, it reacts with the water to produce acetylene gas, which is highly flammable. Find out more & check out the slow-motion footage of this reaction in this video: http://youtu.be/8m5rnr28C58
Memory Metal is a substance which can ‘remember’ pre-determined shape based on it’s temperature. When it’s cold it’s malleable, when hot it’s rigid. This nickel-titanium alloy is used in satellites to unfurl solar panels since it’s more reliable than heavy cogs & gears. In this image you can see a coil of memory metal being placed into a beaker of boiling water. Watch the full video here: http://youtu.be/w12KvC4chBU
In this slow motion meteorite impact we can see the formation of ‘ejecta patterns’ as sub-surface material is blasted from underneath the top layer. These patterns are formed in the creation of impact craters when two celestial bodies collide, typically caused by a meteorite impact on the surface of a planet, mood or asteroid. Impact craters are the dominant geological feature of most moons and asteroids, but are far more rare on Solar System objects with active surface geological processes (such as Earth, Mars, Titan, Europa, and Io), since they are eroded. By studying the size & shape of the crater and resulting ejecta patterns, scientists are able to determine the size, velocity and trajectory of the impactor. Such geological studies not only paint a picture of our solar system’s history, but can also prepare us for impacts in the future… Click here to watch the full video & learn how to make your own craters in a great experiment to try at home.
How do greenhouse gases contribute to Climate Change? Why is the Greenhouse Effect essential to life on our planet? Sarah Stephens of the Live Science Team demonstrates the effect of Carbon Dioxide on Infrared light.
You may have a pet whose eyes appear to glow in the dark. This ‘Eyeshine’ is caused by the tapetum lucidum (the latin for “bright tapestry”). It’s a layer of tissue found behind the retina of the eye in many vertebrates. It reflects visible light back onto the retina, giving these animals far superior night vision. In this image you can see the back of a horse’s eyeball, along with the optic nerve at the base. Click here to watch the full eyeball dissection.
