The Science of Superheroes - X-Men
BBC Science has an interesting article on The Science of Superheroes. I've included some of the article below, but there's much more on other superheroes like Spiderman, The Incredible Hulk, and Daredevil.Levitation
We're all used to the idea of magnetism. Iron and steel are magnetic, and are attracted to either the north or south poles of a magnet. You can also use electromagnets to make levitating trains (called 'Maglev') that float over the rails. These are much easier to move forward than a conventional train that loses a lot of energy as friction between the rails and wheels.
The Maglev trains and rails are fitted with electromagnets that generate two opposing magnetic fields. Just as two north poles cannot be pushed together, the opposing magnetic fields keep the trains a few centimeters above the track.
Floating frogs
Most materials are 'diamagnetic', meaning that they are always repelled by either of the magnetic poles. Water is slightly diamagnetic so it's also repelled by strong magnetic fields.
Since animals are mostly water, scientists have found that if they use a strong enough magnetic field, they could levitate a live frog – and it doesn't hurt the frog at all.

What do auroras look like from space? From the ground, auroras dance high above clouds, frequently causing spectacular displays. The International Space Station (ISS) orbits just at the same height as many auroras, though. Therefore, sometimes it flies over them, but also sometimes it flies right through. The auroral electron and proton streams are too thin to be a danger to the ISS, just as clouds pose little danger to airplanes. ISS Science Officer Don Pettit captured a green aurora, pictured above in a digitally sharpened image. From orbit, Dr. Pettit reports, changing auroras can appear to crawl around like giant green amoebas. Far below, on planet Earth, the Manicouagan Impact Crater can be seen in northern Canada.

Humm we'll have to see what happens with this new technology Microsoft is now pushing. My only thoughts are we the consumers will end up getting it in the end. I can see it now, YOU NEED TO HAVE SECURE SPACE ENABLED TO ACCESS THIS PRODUCT. Turns out when you do enable it you can no long post, copy, share or even archive whatever it is you thought was worth YOUR time viewing/listening to.
