Solid rubber speaker for the first time in the world was created in Japan- VIDEO
Monday, 22 October 2012 08:45


Tokai Rubber Industries from Japan announced about the creation a speaker, which for the first time is made entirely from rubber. The basis for the design of a new speaker is a new material, which called Smart Rubber, which expand under the influence of electrical signals, thus producing sound. The main advantage of the new rubber- is the ability of the speaker to play sounds in a wide range of frequencies, including low-frequency sounds, that can not do a normal speakers, that break when play the bass sounds. Management of Tokai Rubber Industries is looking for partners to start mass production of rubber speakers, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... eaker.html

Dr. Tom Jordan from the University of Bristol and Professor Julian Partridge and Dr. Nicholas Roberts from Bristol School of Biology, found that the scales of certain fish, such as sardines, herring and sprat is arranged in such an unusual way, that allows do not to polarize the reflected light and provide its high reflectivity. In this regard, such fish as sardines, herring and sprat are nearly invisible to predators in the water. This property of the scales of sardines, herring and sprat is formed by the fact, that the surface of the scales contains not one, but two types of guanine crystals, with different optical properties, and the particular combination of these crystals prevents polarization of the reflected light. According to Nicholas Roberts, if we can use these crystals in air, it will be possible to create a kind of suit for the Invisible Man.

Japanese scientists learned how to see the dreams of human- VIDEO

Wednesday, 24 October 2012 14:38


A group of Japanese scientists led by YUKiyasu Kamitani at Neuroscience annual conference in New Orleans, the U.S. reported, that for the first time in the world, they were able to develop a new technology, that allows up to 80% to determine the content of human dreams. Technology of YUKiyasu Kamitani can to determine the main objects, that are present in the dream of the test person. According to YUKiyasu Kamitani , they have created a technology, that shows of presence in a dreams of images, such as - "man", "woman", "computer", "car", and others. The discovery was made in the laboratory of computational neuroscience in Kyoto, Japan, where scientists conducted an experiment, which was attended by three volunteers. Japanese scientists using the imager observed, that certain well-defined objects cause nerve impulses, which allowed the course of the experiment, up to 80% to determine the content of human sleep, analyzing its nerve impulses, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... human.html

Scientists have learned how to see through walls- VIDEO

Wednesday, 24 October 2012 16:55


As reported by Deutsche Welle, the German team of scientists, led by Rudolf Zetik from the Technical University in the German city of Ilmenau was able to create a special radar, that can pinpoint the location of a person behind opaque barrier (such as the walls of buildings). According to Rudolf Zetik, the antenna of radar are consists from three metal funnels, that emit of electromagnetic waves of a certain frequency through the wall and take them back, and by the nature of the received signals, according to Rudolf Zetik, you are more likely to locate a person behind this wall. The idea of Rudolf Zetik is not new, over two months ago on our website, we reported about similar device, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... walls.html

Tractor beam have created through the use of Bessel beams- VIDEO

Thursday, 25 October 2012 14:01


In Physical Review Letters the group of scientists- Professor David Raffner and Professor David Grier from the University of New York, USA published an article, in which they claim, that they have managed to create Tractor beam using two Bessel beams. As reported by Professor David Raffner and David Grier, if use just two of the Bessel beams with a special lens, that alters the specific direction of propagation of rays, that they overlap in the target, it is the target will move towards the source of light, as there is a strobe effect, when the first light of Bessel beam, which puts pressure on the most distant from the observer plane of the body-target, combined with a second Bessel beam, which presses on the same plane at an angle, resulting in the resultant force is directed towards the source of light, which causes this body-target to move to this source of light. NASA considered three main projects of Tractor Beam, which are going to use to clean up the debris and capture of small asteroids, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... -beam.html

Fireflies helped to create a super-bright LEDs- VIDEO

Tuesday, 30 October 2012 11:55


In the magazine Proceedings of the National Academy of Sciences published an article of Korean physicists from the Institute of Advanced Science and Technology of Korea in Daejeon, South Korea, that they have created a new type of high-brightness LEDs, using a mechanism of bioluminescence in Japanese firefly (Luciola lateralis) of family Lampyridae. According to Korean physicists, the creation of these super bright LED has been used in the mechanism of bioluminescence from light emitting nanostructures of Japanese fireflies, in which are located a special tissue of large cells, that emit light as a result of oxidation of the pigment luminiferous molecules of luciferin. According to Korean physicists, part of a new light-emitting LEDs, made as a copy of the nanostructures in the abdomen of a firefly (Luciola lateralis) can be adapted for the production of high-brightness LEDs, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... -leds.html
