More recently Rains in the Atacama Fascicle were the Death of Microbes, Examination Studies


Life as we know that water is needed to live and prosper. But scientists have seen something unusual in one of the driest places on Earth. When Atacama's desert water fell, he took an accident.

Atacama 's Desert, located in northern Chile, is the driest wilderness on Earth and only the most difficult packs can survive. Its hyperid heart has not got water in the last 500 years. When the desert grew last three years ago, it destroyed most of the microbanans who lived there.

"Our company has discovered that, against its potentially careful expectations, has never seen the water ever seen in a flowery life in Atacama , but instead, the waters have made a huge decline in the microbial species that lived in the area before the heavy campaigns, "said Alberto Fairen's co-author from Cornell University.

"Our work shows that high water causes that a majority of native microbial species disappear. The range is extinct from & # 39; reaching 85 per cent, due to the osmotic aggression that has made water suddenly: the self-contained microbioms, which were well-modified to solve under water conditions and their strategies were made better for their environment, have been able to change in line with the new floods resulting from sudden flooding and dying from extra water. "

There were 16 different microbiological species; in Atacama Desert first. There were only two to four species still alive after it had got water.

"The event was extinct," said Fairen. "Our products show for the first time that most of the water supplies to microbiologists – especially suitable for distress that is bad and bad from the most remote environments – killing them from osmotic surroundings. "

The results also affect the understanding of microbiology from very difficult habitats such as Red Planet. The Atacama Desert is one of the Earth's places that have an amazing Mars landscape.

"Mars was the first time, the Noachian (between 4.5 and 3.5 billion years ago), which had a lot of water on the surface," said Fairén "So Atacama's study noted that the recycling of Marsh water could have contributed to the removal of Martian's life, if it were ever, instead of being able to represent a sustainable microbiot that to grow again.
