Every school kid knew exactly looked like dinosaurs: the long tail of getting dragged, cold-blooded

Last sprayed cross Osumi river waters. Attending the ceremony Ilir Meta Nasip Naco Tirana budget Lighten up serious accident in 2016, the hospital director Bulqize Basha: Rama promises in the budget include laughter CULTURE AS A CHALLENGE-in honor of Gjosho Vasisë -
30 years ago, the solar system was a sleepy place. We had nine planets and tens Monday. But these places technika drivers looked like inert and dead - so much we did not know at all. No action, no change.
Today, technika drivers the picture could not be more different. NASA probes have found geological activity on at least three planetary bodies: Jupiter's fiery moon Io, in Enceladusin Saturn and Neptune's Triton. In March documented landslides and sand devils technika drivers on the Martian surface. Observers from around the world have seen Jupiter hit by impacts on at least three occasions, including multiple heating dramatic suffered in 1994 from comet Shoemaker-Levy-9.
And, most peculiarly, scientists are seriously considering the existence of life elsewhere in the solar system. Mars is still the main place to search, technika drivers but another of Jupiter's satellites, icy Europe is a competitor, as is Encelagusi, as well as the largest satellite of Saturn, Titan. The latter even large lakes of liquid methane, which expand and shrink according to the seasons.
Many people think that Apollo represented the glorious technika drivers days of the American space program, but this should be accompanied technika drivers by the word qualified people on board. Program without people on board today has its time of glory. NASA has already sent spacecraft arriving into orbit around Saturn, Mars, the moon and the sun and will soon have one around Mercury, the European Space Agency spacecraft technika drivers has sent around the sun and Venus. AHE is observing a comet: technika drivers Rosetta mission will touch and sit on one in 2014. Similarly, NASA's space ship called "Dawn" will come into orbit around the asteroid Ceres and Vesta in the end of this decade. Already the first eight planets are closer. If you're a fan of Pluto, will have to wait a few more years, until the New Horizons to fly by him in 2015.
Whole libraries technika drivers could be filled with miracles obtained from exploration of the solar system with robots, and we have only scratched the surface. When the man put the foot on the Moon again - or for the first time in March - what will surely find will further enrich the knowledge that our messengers have brought us robotics.
Every school kid knew exactly looked like dinosaurs: the long tail of getting dragged, cold-blooded reptiles, dumb as a box of sedimentary technika drivers rocks. New species discovered each year were mere curiosities, more material for children's books.
The last 30 years have turned all this. It seems that dinosaurs were not destined to perish, and in a sense they do not really ever completely exterminated. Each new dinosaur discovery seems megabishat us that the last millennia are more related to birds like partridges than the Komodo technika drivers dragon. Like birds, they move in groups, care for the young and were probably warm-blooded. And butts? High tail feathers as primarily horizontal and on the ground. The idea that dinosaurs still walk - or fly yet - between us was thrown by John Ostrim technika drivers of Yale University in the seventies, but remained primarily an argument to the mountain of evidence that loomed buried technika drivers all controversies. technika drivers In 1993, in the Gobi Desert, a Citipati bones were found in a position where heat the nest with an egg. Studies of skeletons unearthed hundreds of similarities between modern birds and dinosaurs: hands with three fingers, ankles above the earth. Then, in 1995, scientists began to reveal bits of Sinosauripoteryx, and other feathered dinosaurs from Liaoning province famous in China, while the roof came in 2000 with the discovery of an intact dromaeosaur feathers that had many of the physical technika drivers features of a bird. "It's technika drivers sealed," says Jack Horner, curator of paleontology at the Museum of the University of Montana. Someone might say: see the difference between a European Robin and a T-Rex-i. Of course there are many differences, but the similarities can use to determine proximity. It is a paradigm that has changed. " As for the extinction of terrestrial ancestors of our birds, this piece of the puzzle remains unsolved.
Even medicine has been the golden moment, similar to the separation of the atom in physics: technika drivers the ability to divide, unite and deliver exceptional power that is to genes and cells. The big moment has come from merging the two fields - and the whole gene therapy
