Artificial blood vessels created in the laboratory with a 3D printer  could be used in organ transplantation soon . The major obstacle encountered so far in creating artificial tissues was supplying them with nutrients, which is done naturally through capillaries. A team of researchers from the Fraunhofer Institute in Germany has solved this problem by using a 3D printer and a technique called two-photon polymerisation. There are thousands of patients who desperately needed a transplant and some fail to obtain it in time. Over 11,000 people were put on the waiting list for organ transplantation in Germany only in 2011. To save as many lives as they can, researchers around the world working in the field of tissue engineering have attempted to create in the laboratory artificial tissues and even whole organs. "The individual techniques are already functioning and they are presently working in the test phase; the prototype for the combined system is being built," ...

Superstring theory is an effort to find an answer for all of the atoms and cardinal forces of nature in one hypothesis by molding them as oscillations of tiny supersymmetric strings. Superstring theory is a stenography for supersymmetric string theory because contrary to bosonic string theory, it's the adaptation of string theory that contains fermions and supersymmetry. Physicist Brian Greene gives a short explanation of superstring theory, a concept that minuscule strands of energy vibrating in 11 dimensions create every particle and force in the universe.

SixthSense is the latest effort from Pattie Maes and Pranav Mistry. The setup features a camera, a projector, a little mirror, phone and colored caps. The components communicates with the cellphone that will access all the data you need. The system tracks the four fingers and recognizes various gestures (zoom in/out, take a picture, organize, resize). It's still a work in progress but its capabilities are just amazing. Price: $350.
