Malicious piran'i proved to be by the large cowards

In spite of ominous reputation, piran'i in reality not too are terrible. And even on the contrary, they themselves in all to fear. To this conclusion came the researchers of university St Andrews (Scotland) and institute Mamiraua (Brazil).

Previously scientists assumed that piran'i are collected by flocks in order to attack its victims. Now, after conducting the more in-depth research of the means of the life of sadly famous small fishes, scientists understood that piran'i are completely peaceful. They feed by small small fry, algae and insects, not on whom they will attack nor are gathered never into the flocks in order to be protected from the predators, such as river dolphins and caimans. Moreover, the greater the danger in them it threatens, the greater the flocks they form. The largest accumulations of piraniy are noted in the shallow sections of the Amazon, where it is too small place in order to be hidden from the predators.

Squirrel "stopped" the aircraft

The aircraft of company American Airlines, which flew from Tokyo, made the unplanned landing to Honolulu after pilots heard the strange sound of above their cab. Then it was explained that the ticketless squirrel emitted sounds.

The voyage of Tokyo - Dallas it was necessary to plant, since the pilots feared, that animal can pogryzt' installation or create other problems, stated the representative of avikompanii to the correspondent of newspaper Honolulu Star-Bulletin.

After the aircraft landed, all of 202 passengers were arranged into the hotel numbers, and then their tickets were perebronirovany to other voyages.

Where and as protein it fell onboard the aircraft, it is unclear, until now. However, fearing, that it, possibly, is infected by fury, authorities killed rodent.

Chimpanzees refuted Engels's theory

The stones, found on the West of Africa, at first glance were differed in no way from usual, and only radio carbon analysis showed that the discussion deals with the scientific sensation. It occurs, chimpanzee possessed the habits, which, until now were considered exclusively the privilege of man. This refutes the famous theory, which they presented to Soviet schoolboys as truth in the last instance.

The Stone Age - one of the most prolonged epochs in the history of humanity. This was the bloom of primitive communal system. Stone was used for preparing different instruments, be it knife or axe.

Undoubtedly, the implements of labor and weapon from the tree were also disseminated, but they were not preserved to the present. Therefore into the hands of archaeologists fall only the roughly polished pieces of silicon, rock plates and other objects of the daily custom of ancient person.

However, rock instruments, as now it is explained, used not only people. Scientists assume that the stone- hammers, found on the West of Africa, belonged to chimpanzee, since on their form they most be suitable for the large hand of this monkey.

Now experts break head, as generally in chimpanzee appeared this habit. Two versions are proposed - either this special feature was inherited from the general with the man, now died out ancestor or it developed in monkeys in the process of evolution parallel with the man.
Paleonthologist Julio merkader and its associates made their discovery in the territory of republic tomcat -d'Ivuar in the earliest prehistoric "settling" of chimpanzee.

The stones obtained there, are at first glance, they are remarkable in no way, and after thoroughly study it became clear that 4 300 years ago them used prehistoric chimpanzees.

Apparently, monkeys used them in order to split nuts. To this conclusion the researchers came after the comparison of finding with the rock tools of ancient person and the instruments of contemporary chimpanzees. This version confirms the fact that in the cracks of rock hammers grains of starch are discovered.

"the rock culture of chimpanzee has long prehistory and deep roots, which only begin to be opened. The age of rock tools was determined because of the radio carbon analysis ", write researchers in their article, published into Proceedings of the National Academy of Sciences.

Thus, the driven into into head of Soviet schoolboys assumption of Engels about the fact that the labor made from the monkey of man, sequential time is disproved. It is complicated to answer a question, that generally it follows to consider labor. The obtaining of food with the use of different tools is inherent not only in mammals, but even birds. But some humourists completely declare, that not the labor made from the monkey of man, but precisely the opposite - idleness it made from the man a monkey.

Do not catch shark by the tail

South African boatman fell into the large trouble, by mistake after gripping for the tail the dangerous shark of zambezi.

Richard tebbutt swam on his of kanoe along Nakhun river, when he saw on the shore of fisherman, who attempts to pull, obviously, very large ribband. Richard jumped out from kanoe with the intention soak to fisherman, reports Dispatch.

I dived and gripped fish for the tail. Which there was my horror, when I saw, what ribband - is the large shark of zambezi. It rapidly turned itself and gripped me for the left hand. Through the fraction of a seconds I saw in the water the blood.

there was output not and 4 of all forces it struck shark by right hand in order to force it to let go me - it recalls. For victim it was possible to drive off three-meter predator, but several instants after it attacked again. I had time to jump out from the water, it would be otherwise already dead.

He already understood on dry land Of tebbutt that it lost much blood. Its son, who arrived in time to the aid from the boat, called the friend of family, who delivered victim into the hospital. On the injured hand they there put 50 seams.

The drunk moose terrorizes Swedish children

Students of one of the Swedish schools to the period became real hostages - them terrorizes... drunk moose. Policemen say that animal, probably, ate till full in the garden of the wandered apples, reports Sky News.

Jaehn caiman, policeman from Molndala will sweep aside, to deal concerning the drunk moose can become present problem. First, adult mature moose weighs more than 500 kilograms, and the management of school reported that it behaves completely madly.

children are very frightened, they cannot leave the building of school, it writes newspaper Gothenburg Post.

The police has already been connected with the hunters: if moose not protrezveyet even it will not be quieted, it is necessary to shoot down it.

Sun returned to Italian village

The village, located in foothills of the Italian Alps, which three months in the year is practically deprived of sunlight, decided to brighten its winters with the aid of the gigantic mirror, which will reflect light to its central area.

On this week of 197 inhabitants Viganelly (Viganella), by that buried in the narrow valley of anthrone, to the north of Torino, will be collected on occasion of the arrival of the made to order steel sheet with a width of 8 it is meter and by height - 5. It they will deliver by helicopter to the fixed point on the slope of mountain.

The mayor of village, Perfranko Of midali, who leads project, it is confident, what village more not will suffer from the complete absence of straight sunlight during 83 days in the year - from 11 November through 2 February.

With weight more than one ton the mirror will be placed among the pine trees on the peak of Swedish coal, its height reaches 1.080 it is meter. The motors controlled by computer will allow mirror to follow the sun, reflecting its rays to the rural area and illuminating during six it is hour during the day area in 270 square it is meter.

The cost of entire project - almost 100.000 Euro- - partly covered particular bank, the remaining part of the money introduced rural and local councils. The producer of mirror guarantees, that it is capable of maintaining the highest winds, and will serve, at least, 30 years.

Sharks disappear, because of their fins

The large part of the world population of sharks can disappear into the next 10 years, if the present tendency of the catching of this marine predator is preserved. This communication gives agency Sinhua with the reference to the statement of the defenders of environment.

One third of more than 400 it is specific sharks it is located under the threat of disappearance or it approaches this fateful feature, notes Sara Fowler from the universal organization for the protection of living nature.

fishing can destroy from 50 to 90 percent of the sharks only in 10 years, she stated Fowler, coming out at the conference on the problem of the retention of sharks, which passes to Peking. Yearly because of the fins they kill from 38 about 70 these million earliest predators.

She and other experts, who participate in the conference emphasize that the government and non-government organizations must closely collaborate in order not to allow the barbarous capture of sharks.

"cold" mice live longer

Scientists report that the mice, in which is lowered the temperature of body as a result of genetic mutation, live longer.

The previous studies showed that a decrease in the temperature of body is capable of slowing down aging process and of prolonging life in cold-blooded animals - fishes, worms and flies. But scientists did not know, until now, is it possible to dostich' a similar effect in the birds and the mammals.

Researchers from the California institute Of skrippsa reduced the temperature of body in mice with the aid of the genetic mutations in the cells in the section of the brain, which answers for the regulation of the temperature of body.

Thus, the command of scientists created the mice, the temperature of body of which was below normal. This small change increased the lifetime of animals by 15 percent.

Interestingly, while males lived on the average 12 percent longer, the lifetime of females increased by 20 percent.

These data can soak to the development of the new methods of treating the diseases, connected with the aging, researchers assert.

The preparations, which reduce the temperature of body, can, possibly, replace the application of ice in the surgery, which presents danger because of reduction in the inflow of the blood to the brain

Elephants possess the ability of self-identification

Scientists established that the elephants learn themselves in the mirror. Thus, they entered into the club of the realizing themselves animals, members of which are the highest primates and dolphins.

According to the psychologist from the university Of emori to Atlanta, the complex social life of the elephants, noted for their altruistic behavior and with the large size of the brain, made these animals logical candidates for checking of realization.

Mirror was placed in the cages of elephants in the zoo Of bronks in New York, in which be situated three inhabitants. The first question was, do greet they reflection, as if they meet another animal. However, elephants did not be mistaken, and was used mirror in order to examine its own reflection. For example, they moved aside trunk to the side in order to look around the internal cavity of mouth.

In contrast to the previous studies, this is the first experiment with the use of an enormous mirror, which allowed elephants to concern its surface, to rub and to be turned to it by back.

The attempt to look to itself from the back is one additional indicator of self-consciousness. One of the elephants passed the test, when it touched the mark on the tail end of the head after it looked into the mirror.
