Magnetic levitation , maglev , or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields . Magnetic pressure is used to counteract the effects of the gravitational and any other accelerations. Earnshaw's theorem proves that using only ferromagnetic or paramagnetic materials it is impossible to stably levitate against gravity, but servomechanisms , the use of diamagnetic materials, superconduction , or systems involving eddy currents permit this to occur. In some cases the lifting force is provided by magnetic levitation, but there is a mechanical support bearing little load that provides stability. This is termed pseudo-levitation . Magnetic levitation is used for maglev trains , magnetic bearings and for product display purposes.

By Jaya Narain UPDATED: 08:55 GMT, 24 February 2012 If you’re the sort of person who spends ages looking for your mobile phone, Google may have the answer. And the solution will be right in front of your eyes – literally. The technology giant is close to launching a pair of futuristic glasses that would deliver all the services of a smartphone straight to the wearer’s eye.
I’ve heard many people taking about technology as a whole and that it’s not advancing as fast as in recent years which will eventually lead to a stagnation. I don’t agree at all with this statement and I believe that the advancement in technology will blow the mind of those who disagree. Per example, take a look at a technology called Sixth Sense developed by a MIT research assistant called Pranav Mistry. During the TED conference a couple of years ago, Pranav demoed a portable projector which gives people the possibility to interact with objects and the information displayed by the objects. When Sixth Sense will be adopted at large scale will allow people to see the reviews of a book in real time then holding the book.

There's no question, drugs work in treating disease. But can they work better, and safer? In recent years, researchers have grappled with the challenge of administering therapeutics in a way that boosts their effectiveness by targeting specific cells in the body while minimizing their potential damage to healthy tissue. The development of new methods that use engineered nanomaterials to transport drugs and release them directly into cells holds great potential in this area.
