Rivers under the Antarctic ice.
British scientists have discovered that deep beneath the Antarctic ice flow of the river, which - as reported weekly "Nature" - can connect with each other Ice, ancient Antarctic lake. The existence of lakes hidden deep beneath the Antarctic ice, panasonic Panasonic scientists have learned in the '60s Since that time, was discovered about 150 podlodowych lakes, but - as investigators suspect - the actual figure is much higher. Deprived of contact with the air of the lake does not freeze because of the ruling under enormous pressure and ice cream. Scientists often want to bore to the surface of the oldest lakes discovered - concealed nearly 4 kilometers beneath the ice of Lake Vostok - and take samples for testing. Speculated that it could keep the microorganisms not found in any other place of Earth, able to survive in extreme conditions . Opponents of the plan but argued that these actions contaminate last unspoilt areas of our planet.

What is a "supernova"?
Big star during his life passes through several stages, in which successive elements are changing more and heavier. The heaviest element that can be produced in this way, the iron (smaller stars do not come to that stage). Later, the pressure inside the star is too small and the core collapses under the influence of gravity can lead to "crushing" of atoms - electrons and protons react with each other releasing enormous energy released in supernova explosions. The outer sheath is rejected and the stars flash is so strong that it can overshadow the brightness of the galaxy. Remnant of a supernova is irregular nebula, which lies in the middle of a pulsar.

They've created a virus
There is no virus - oh, there is a virus - can be summarized as a feat of scientists from the State University of New York. Like a modern sorcerers have created something from nothing, well, almost anything. Was only prepared to rule, or genetic map. But we did all the components themselves - Eckard Wimmer told Reuters. Could a duration of two years of work describes today's Science. "Their effect-completely artificial polio virus - is undoubtedly one of the greatest achievements of virology" - says in a comment. His work instead of a hat scientists have drawn from the tube. The fact that the artificial virus is in no way inferior to the natural, are beginning to discover the healthy mouse poison, which fell as a result of polio and died.
