Rodents, speak complex languages, birds warn of approaching danger. North American owls rabbit , which often make their home on the outskirts of settlements prairie dogs overhear conversations of their neighbors rodents. Owls do not do it for curiosity, but for their own safety. Scientists from the University of Colorado found that prairie dogs with special “words” transmit signals to each other about approaching snakes . Eavesdropping dogs, owls receive important information about the impending danger. Although reptiles predators in most cases do not pose a threat to adult birds, they can destroy the owl eggs, ruining the nest. Prairie dogs , who, unwittingly, help neighbors, speak a complex language with the rudiments of grammar . Scientists have
found that in their lexicon has independent parts of speech – nouns, adjectives, verbs and adverbs . With words of rodents squirrel family can describe approaching a living creature or object in detail. For example, scientists have found that person in a blue T-shirt with long sleeves they react differently than a man in a gray T-shirt with short sleeves. In the case of snakes, dogs stand on their hind legs and closely examine the terrain. If a predator approaches, rodents attack him. Owls , which also have their own language, not react to all the sounds, namely those signals danger . Study leader Rebecca Brown said that scientists have conducted a kind of test, studying the reaction of the birds on barking dogs, mooing cows, and the sound of low-flying aircraft. It turned out that it cries dogs make owls react particularly active – birds tremble, rotating head and pressed to the ground. conclusions that scientists have published a paper in the journal Ethology, once again prove that the animals that live in the neighborhood are in the complex interaction, helping each other to cope with all sorts of dangers.
Antarctica is collecting cosmic dust left over from comet ISON. According to the press service of “Arctic and Antarctic Research Institute,” work performed Russian explorers. In the experiment, from 7 to 11 January was laid 150 square meters of ultra-pure polyethylene, which should serve as the working out of methods and data collection reversing. January 15 scientists spread this material over an area of ??45 square meters, to determine the background of cosmic dust deposition conditions. It is expected that it will collect when the tail of the comet enters the Earth’s atmosphere. Analyze the information entrusted to
employees of the St. Petersburg Institute of Nuclear Physics in Gatchina. Earlier it was reported that Russian scientists decided to look for signs of cometary dust in extraterrestrial life. Researchers calculated found on microscopic particles of organic molecules. In the astronomical environment was expressed criticism on the matter. In particular, it was noted that the chances of finding the remains ISON, needed for the experiments, are extremely small. ISON opened in 2012: it did astronomer from Russia Artem Novichonok. She was named Comet century, as it was extremely bright, and it was assumed that since December 3, 2013 Earthlings could see it with the naked eye. However, on November 28 the comet should pass perihelion – the closest point to the Sun’s orbit – and since then researchers have lost her. It was assumed that ISON could disappear before the perihelion passage, unable to stand closer to the star.
Attackers attack U.S. retail chain Target using virus KAPTOXA, bought up a malicious program on the black market, and then created their own method of attack on the terminals to read bank cards. About it writes The Washington Post. About hacking terminals and credit card data theft American chain Target announced in late 2013. Recently in the press reported that penetrated computers of the virus was written “partly in Russian.” Malicious program did not recognize the existing anti-virus tools. So hackers who wrote the virus showed a high qualification.

According to a report prepared by the iSight, the organization on whose computers appeared the virus may not be aware that they are infected. Also they are unable to keep track of which data has been lost as a result of the attack. All the matter, according to experts, is that KAPTOXA able to “cover his tracks”, hiding their activities.
