Chilean Antarctic Institute today released the results of its latest issue Scientific highlights including a finding related to paleontology and climate change.
addition of antioxidants and radiation-resistant organisms, bacilli were located living in extreme environments, microorganisms that live without light, bacteria that could improve the production of antibiotics and fossils that illuminate the green past the white continent. All these were some of the topics discussed by the participants of the expedition, the "largest organized so far by Chile.
researcher at the University of Georgia, Jenny Blamey, revealed that in his opinion, was the most telling finding: the "Deinococcus" a microorganism capable of withstanding the radiation emitted during the nuclear disaster, the most harmful to living organisms. "It's a very important discovery because this organism is capable of withstanding 5,000 times more radiation than any other and it does not happen mutations," he said.
addition, a paleontologist at the University of Concepción, Marcelo Leppe, drew connections between the Patagonian and Antarctic territories, spaces that hide a "paleontological treasure" and explaining the general history of the time when they disappeared dinosaurs, the Cretaceous. He added that, in his view, could Chilean Patagonia set up a "Cretaceous Park", an area "unique giant" for the creation of sustainable tourism. "What is not known, is destroyed. The best way to protect these areas is to make them known," he said.
"There are 28 countries that conduct research in Antarctica. Of those 28 programs, 15 entrants Punta Arenas, ie more than 50%. That allows us to rely on foreign support and foreign Antarctic support programs," said Inach director, José Retana. He added that "there is no Antarctica, but several, as the" last "continent has temperatures ranging between 5 degrees positive and 90 negative. "Antarctica is like another planet. Having it so close is an exciting challenge for the Chileans" he said.
The last continent has an environmental variety that has allowed the acquisition of "valuable" information on more than 200 microorganisms "unique", "who have never been studied," said Jenny Blamey. The tests yielded findings related to biocomposites with antioxidant properties, "very important to women," he joked, because of its ability to generate rejuvenating and protective properties against ultraviolet sun rays.
The study, which lasted more than four months and in 2010 completed 34 projects, was the participation of 124 researchers, with 56% of studies conducted in partnership with other countries, as detailed scientists during a press conference.
