In the 1970-ies the British epidemiologist Richard Peto from Oxford noticed that the probability of cancer in large animals are no more than small ones. Meanwhile, everything had to be the opposite: the larger an animal is, the easier it is to get the tumor. This consideration seems logical, given the fact that all cells are about equally likely to transform into malignant. And if the large animal cells more, and tumors, they have to appear more often. This, however, is not observed, what Mr. Peter concluded that large animals have some anti-cancer mechanisms that are not small animals.

Many organisms living at hydrothermal vents on the sea floor, depend on a very specific energy resources like methane or hydrogen sulphide. Usually such animals cohabit with bacterial symbionts that and process this alapetite "chemistry" in more available to the body shape. However, such sites on which of the strata of the earth in the water facing methane, hydrogen sulfide, etc., can defend from each other for hundreds of kilometers. And then the question arises: how animals that depend on such sources are distributed between them?

If to take pictures of the Sun with the help of an ordinary camera, you get dull yellowish disk. If you do this when the light closer to the horizon, then added some red (only)because between you and the star will be more of the earth's atmosphere, scattering of waves in the blue part of the spectrum.

Several arcs identified around Betelgeuse is closest to the Land of the red supergiant - in a new image taken by the space Observatory "Herschel". The star and her curved shields may encounter the mysterious dust "wall" five thousand years.

Shelf are willing to join the asteroid wealth arrived: January 22, 2013, announced the creation of start-up Deep Space Industries (USA). His first reconnaissance probes will be sent to asteroids "till 2015". Then it is planned to create a fleet of small satellites for detailed geological exploration and subsequent production of minerals.

Thanks to recent work of the American astrophysicists the title of the oldest stars awarded HD 140283 that shines just 186 light years from Earth. This number is 13.9 billion years, making it shone almost the same age as our Universe. But the interesting thing is that this "old" - typical star of the second generation.

It turns out that fears remember not only people were fears have even more power over such ferocious predators like sharks. These marine killer afraid specific electrical discharges. This behaviour is formed already in embryos - a kind of electric field akulenok can understand, there are any number predator, or not.

Until recently, altruism was considered "anomaly" behaviour, acquired in the process of social development.

Any weapon, based on previously not used physical principles, more and more attracts the attention of the military, because the promises great benefits to those who will manage its first use. One such innovative projects is magnetohydrodynamic explosive weapons MAHEM, striking objects jet of molten metal.

Recent excavations of the ancient city in Crimea artesian once again pleased archaeologists. Scientists have found numerous fragments of terracotta figures of Greek goddesses and gods, Hiking and horse soldiers, fragments of different dishes and, most importantly, dozens of Bosporan coins, most of which were later coins Mithridates VIII.

That is what happened with Uranus and Neptune - planets of the Solar system that astronomers have repeatedly seen, but felt that watching unknown stars.

Compiled by the world economic forum report, which lists the natural phenomena that can destroy our planet, suggests that worrying is pointless, says Elena Dusi in an article published on the website of the newspaper La Repubblica.
