Is this evidence of life on Mars?

Curiosity is expected, the rover is currently traveling to Mars, make a dramatic landing in the crater Gale to mid-August and begin your search for geological signatures of a watery past and friendly to life on this planet. The evidence strong that at some point there were large volumes of water on Mars would be an important step in the search for life on the Red Planet. But ... Have you already been found?

Some scientists say yes. Researchers at universities in Los Angeles, California, Tempe, Arizona and Siena, have published an article in International Journal of Aeronautical and Space Sciences (IJASS) citing the results of their work with data obtained by the Viking mission NASA. twin Viking landers 1 and 2 were launched in August and September 1975 and landed successfully on Mars in July and September next year. Its main mission was to look for life, what they did by digging in the red Martian soil for signs of breathing, a sign of biological activity. The results, although promising, were not conclusive. Now, 35 years later, a team of researchers says that the Viking landers, in fact, detected life, and the data has been there all along. "active soils exhibited a rapid and substantial release of gas, "explains the team's report. "Probably the gas was CO2 and possibly other gases containing radiocarbon. " Applying mathematical complexity of the Viking data to achieve more thorough analysis, researchers found that samples of Martian behaved differently than a control group biological. "control responses exhibit initial order comparatively low fell rapidly to a nearly random noise, while the active experiments exhibit a higher initial order that decays slowly, "says the article. "This suggests a biological response robust. " While some critics argue that such a discovery process IDENTIFICATION life has not been perfected - even on Earth, the results are certainly interesting. .. enough to boost support for further investigation of the data from the Viking and perhaps reassess the findings "inconclusive" the historic mission.  "What we know is a drop of water, what we ignore is the ocean.
