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.

A fresh study by the University of Glasgow, brought out today in the Proceedings of the Royal Society B: Biological Sciences, evokes that our life expectancy is probably influenced by how much tension we were exposed to early in our lives. The research also depicts that early life stress underwent by our partners may affect our lifespan. “Other research led us to expect that increased stress exposure in early life would reduce adult lifespan’, said Professor Pat Monaghan, “but we were not expecting such a big effect on breeding partners. Unstressed birds had mortality rates that were four times higher than normal if they were simply given partners that had experienced stress earlier in their lives.” The group of researchers considers that contribution to the reason for the partner effect could be that these tense souls are not very comforting to be with. Agreeing to Professor Monaghan, “The take home message is that the wrong kind of partner can be very bad for your health.” It...

If you are baffled at the slow speeds of wifi internet when more than one device is tapped into your network you should know that radio waves are merely one part of the spectrum that can carry our data. What if we could utilize other waves to surf the internet? Harald Haas (a German physicist), has developed a solution he calls “data through illumination”—getting the fiber out of fiber optics by beaming data through an LED light bulb that alters in intensity more accelerated than the human eye can follow. Haas alleges his conception, which he calls D-Light, could develop data rates more bolted than 10 MBps, which is quicker than your common broadband connection. He foresees a time to come where information for laptops, smartphones, and pads is aired by the light in a room. And security measures would be a breeze—if you can not envision the light, you can not access the data. You are able to guess all sorts of functions for this technology, starting with public cyberspace acces...

Columbia University men of science have developed a $1 plastic chip that can diagnose HIV and syphilis in 15 minutes. The chip named the "mChip", a credit-card-sized piece of plastic that is made applying a plastic injection molding process, examinations for multiple diseases with just one pinprick of blood. Nothing moves inside the chip, and the microfluidics-based chip can be examined with assist from a cheap visual sensor. Concording to results issued this week in Nature Medicine, the chip detects 100% of cases when utilized to test HIV or syphilis and human immunodeficiency virus together, with a 4% to 6% false positive rate. That's same to what is ascertained with common laboratory exams in the developed world. An mChip that can diagnose prostatic adenocarcinoma has already been authorized for use in Europe. In the future, Columbia investigator Samuel K. Sia trusts to practice the chip to examine pregnant women in Rwanda for HIV and other STDs. Numerous of...
