American chemists have used squid protein to create labels stealth, able to hide soldiers from infrared cameras. Their achievements scientists will present on March 23 at the national conference of the American chemical society, says Science Daily.
In modern uniforms is usually applied brown-green camouflage pattern, allowing the military enough to effectively hide the background foliage in the daytime. However, at night the soldiers are often vulnerable to infrared sensors.
To solve this problem Alon Gorodetsky (Alon Gorodetsky) from the University of California, Irvine took the skin of a squid, is able to campfireusa under the countryside, waiting for prey. On the skin of the clam are special cells (iridophore), containing several layers of protein reflective. A cascade of biochemical reactions allows them to change the density and the arrangement of the layers, and that changes the reflective properties of the skin, and therefore its color.
The group Gorodetsky has set up a special bacteria on the production reflective and coated protein dense plate. However, for color changes (similar to those that occur in Yadollah) requires a special mechanism. First, scientists have considered using vapors of acetic acid, but for actual combat conditions the reagent is too fragile and insecure.
In the end, Gorodetsky produced films from reflecting polymer substrates: we are talking about public with duct tape. Such films can be pasted on the uniforms and camouflage mechanical functions run - through stretching.
The scientist expects to produce rolls of inexpensive disposable film that the military will be able to get out of satchels, deploy, stick on the uniform, and then removed and discarded.
Now Gorodetsky working to increase the flexibility of labels, and configures them for the reflection of radiation in the mid and far infrared range (which employ thermal imagers).
In the source code preview-Android version 8.0 has found numerous mentions of the reduction oc-dev, which can be deciphered as Oatmeal Cookies "oatmeal cookies". After the publication of the material Twitter users also noticed the mention of "oatmeal cookies" on the presentation slides from Google I/O.
Engineer Marek Batchinski created an unmanned robot from the potatoes. The root was connected to a super capacitor for energy accumulation, the engine and the wheels. For charging electric potato takes about 15 minutes, after which he can drive eight inches.
Creative Director of Beyond Good &Evil 2 Michel Ancel showed an early version of the gameplay engine, Voyager. This content was shown at a private press preview during the E3 conference. According to Ansel, the movie is a kind of mixture of real gameplay and a techno-demo.
The death toll in the result of ignition of a fuel tanker in Pakistan has increased to 148 people, more 50 injured are in critical condition. Earlier it was reported about 123 casualties and 40 wounded. Local residents set out to collect fuel from the capsized razlichie on highway tanks.
Forwards the St. Petersburg "Zenith" Alexander Kokorin and Artem Dzyuba recorded message after the departure of the Russian national team from the confederations Cup. Smiling, the players did the typical hand gesture, usually indicating a moustache. The only person in the team wearing a mustache, is the head coach Stanislav Cherchesov.
Set in Odessa memorial plaque to the Marshal of the USSR Georgy Zhukov disappeared in the night of Sunday, June 25. The recording of activists in social networks on the removal of the sign drew the attention of the media. In may, the city dismantled the stone laid at the future site of the monument to the military leader.
