New system 3d
For TV researchers and Japanese engineers have made progress on a new technology of 3d TV that manages to overcome some of the historical limitations of this system, for example, the new approach frees the viewer of glasses, provides greater flexibility in viewing and increases the quality of the images. This could mark the beginning of a new stage in terms of the use of 3dtechnology in the television field.
This comprehensive system of 3d TV has been developed and improved in recent years. One of its major progress is to be based on a set of large lenses (400 horizontally and vertically 250), not requiring that viewers use glasses, in addition to providing greater flexibility in viewing.
According to the makers of this new approach, their biggest advantage is that itis specially designed for systems of mass, allowing viewers to enjoy 3d moving images, from any position and in real time. To achieve this required a complex mechanism of lenses, cameras and projectors.

Metaflex

Designed by scientists at the British University of St. Andrews, metaflex is the name of a material that brings us one step closer to the manufacture of fabrics that will allowcreating the effect of the invisibility of the objects.
The metaflex is a meta-material, or what is the same, an artificial material that presents unusual electromagnetic properties, properties that come from the designed structure and not its composition.
In the past have already developed meta-materials that curve and channel light to turn into invisible objects at long wavelengths, but visiblelight poses one greater challenge. the small wavelength of the light of the day implies that the meta-material atoms have to be very small, and so far these minor atoms only have could be on surfaces flat and hard, incompatible with the fabrics of the clothes.
The novelty that brings this work is that the metaflex consists of flexible meta-material membranes, created through the use of a newtechnique that has made it possible to release the meta-atoms of the hard surface on which were built. In this way, the metaflex can operate at wavelengths of about 620 nm within the region of visible light.
The union of these membranes could produce a "smart fabric", which would be the first step to produce a layer or any other garment to "disappear" the person that ports la. The meta-materials,therefore, give us the last impulse to manipulate the behavior of light.

They reproduce a retina cells mother

The magazine nature has echoed in the news that scientific Japanese have that mouse embryonic stem cells spontaneously become the laboratory in a retina, the structure from which the eye develops.
Had so far never been achieved create a quilt as complex as it is a retina in vitro. Theresearchers plunged the embryonic stem cells in a mixture of nutrients. Then, without more help, the cells themselves specialized and organized spontaneously to three-dimensional shapes. Thus open pathways to new treatments against eye diseases. To date, it was believed that stem cells were only serving to replace tissues, muscle or liver, compounds of a single cell type. Scientists came toaccept that the generation of a more complex set of cells was only possible through chemical interactions with other tissues during gestation. the novelty of this study is on that has been made to transform established a mouse stem cell in what they called an optic Cup, a three-dimensional structure that gives rise to the retina of an eye.

Material auto repair

Swiss scientists have developedpolymers that have the inherent capacity to auto repair by exposure to ultraviolet light and which could be extremely useful in areas like packaging, construction, transport, prolong the life of materials that are used in numerous applications.
Most of the materials based on polymers are repaired by the direct heating of the affected area, however, here have developed a rubbery material that...
