Study on the mechanism of the United States use of animal skin new camouflage material

According to United States Fox News recently reported that includes molluscs, squid, Octopus skin will quickly be consistent with the surrounding environment, thereby cleverly avoiding predator Hunt, thanks to has a unique vision on squid skin proteins. United States scientists plan to study this unique ability of squid, and produce similar material for human use.

Rice University, the University of Maryland and marine scientific research team of scientists of the research office focuses on the Visual protein to ascertain mollusc depending on how the protein of the skin to receive the light and to help them adjust skin mode. Depending on the protein is usually inside the eye to feel the effects of light, but in 2008, the scientists found that molluscs also contains proteins in the skin.

Mollusks “camouflage”, in addition to its enemy is very much in the sea, they are not born anti-chemical weapons, the only means of escape is to make themselves look like his own. But with the Chameleon by hormones to change the appearance of a different blood, mollusk by manufacturing camouflage colors of the nervous system, skin color from the surrounding environment to quickly make a consistent, this process may take a few seconds, a few minutes or even hours.

Mollusc itself does not have color vision, so how do they make “camouflage color” background color and fit perfectly? Scientists found that molluscs are included in the skin and in the retina of the same protein, this means that certain substances in the skin can detect light and respond to them.

Hand in hand, scientists are looking for Squid can detect different wavelengths of light as the proteins in the skin, at the same time clarify the molluscs such as protein in the body is built and how sensors are embedded in the materials so that people can use the animal in a manner to perceptual fiber and color, and so on.

Rice University engineers plan to use the members of the team of sidifen·linke manufacturing of nano-materials to build a new “camouflage” material, this material can be used with molluscs skin see light and quickly change colors in the same way.

Japan nuclear accident spread of radioactive material floating to 8 km of the global

Zhongxinwang, May 12, according to’s Kyodo News Agency reported that Japan Fukushima University published on 11th balloon observations show that by Fukushima’s first nuclear power plant accident releasing radioactive material is probably one of 6~8 near km altitude. Vertical height to identify one of the radioactive material is the first time. According to reports, the team will be through the application of the prediction of radioactive substance diffusion Foundation data to improve forecast accuracy. Research group leader, Fukushima University Vice President du Bian Ming said: “the results show that (by accident) the release of radioactive material has been worldwide diffusion. But since not immediately fell to the ground, so it does not affect health. ”

It was reported that Watanabe on April 15 in Fukushima city balloon for every day during an observation, determined to 20 km/h high levels of radiation from the ground. Measurement result displays, beta rays near the surface is about 134cpm (CPM for radiation units), decreasing radiation as the balloon rises, and 6 km altitude increased levels of radiation, at 8.2 km high peak 506cpm. Beta rays are typically about 80cpm.

Reports that from nuclear power plants release radioactive material may have been in the atmosphere of the junction of the troposphere and the stratosphere and troposphere, Earth one a few times.
