Weekly Tech Article: 4/22

The grand prize at this year's Geneva Inventions Show was Cheah Kok-wai, a professor from Hong Kong Baptist University, who came up with a way to make phone screens more durable.  His solution: a thin layer of sapphire over the screen.  The sapphire is applied with extremely high heat and, because of sapphire's properties, transparency is not affected.  Also, the layer is thin enough that touch screens are not affected.  Because sapphires are so rare, Kok-wai is in the process of accomplishing the same goal, but with quartz instead of sapphires.  To read more, click here.

Tech Article 4/15

Researchers at Universitat Autònoma de Barcelona Universitat Autònoma de Barcelona have created a wormhole-like object to teleport objects.  A wormhole, in theory, can get an object from one end to the other in literally no time.  The sphere that the team created accomplished a similar feat.  The sphere has three layers: an outer shell that is capable of being magnetized, an inner shell that is a superconductor, and a coil inside the inner shell that is, like the outermost layer, capable of being magnetized.  The result was that when the sphere was submerged in liquid nitrogen and magnetic charges were shot at the opening on one side of the sphere, the charge was released from the opening on the other side of the sphere.  On the inside, however, there were no traces of any charges going through the sphere.
