Eat sulfur, breathe from banner: Sciences that get deep underground life Divisional News



Scientists expose the results of ten research of ten years ago; opened the world and mystery of deep deep underground earthquake that could help to explain how life began on Earth and how it could look at other planets.

"We are not all the branches of life that we all knew there," said Karen Lloyd from the University of Tennessee. "There are deep branches in a tree of life that never one has ever known and many are in the horizontal."

Lloyd is one of hundreds of scientists from around the world involved in the Deep Carbon Theater, which is a carbon action survey that has a lot of kilometers below. Members of the team who watch the carbon is that; empowering life outside their results this week at an American Geo-American Union annual meeting.

Scientists have a knowledge of microbes living beneath the surface since they were first discovered in oil deposits in the 1920s. But over the last 10 years, it is clear that the genetic diversity of tiny little creatures that live in microscopic poles and clusters under the corresponding legs are equal to the above surface.

Nearly three quarters of the earth's fruit and Archaea (a type of son) live in the exile, now say science. All types of cell life can be found, and include the type of cell life; make up the well-known plants and animals, there.

These animals have up to 2.3 billion cubic kilometers – almost twice the seas. Some remain in temperatures up to 121 C; others find that there are more than 10 kilometers below the seas.

In general, the level of carbon in which the bacteria is between 245 and 385 times is larger than those found in humans.

It's a strange world, where micro-mittens are there; pull energy from sources such as radiation, "eat" breathing and "breath breath".

"That's how life can even be maintained even though there is no potential to get energy from the sun," said Barbara Sherwood Lollar, University of Toronto. She got microban in 2.7 billion billion in depth water in the Shield of Canada.

"They breathe things out," said Rick Colwell, Oregon State University. "Many of them are able to use oxidic iron how we use oxygen."

Sherwood Lollar says that it's a chemosynthetic life rather than life on the surface, which is dependent on photoynthesis.

Things will happen slowly there. Microbes from the depths can create hundreds or even thousands of new uninhabited years. Instead, they repair damaged molecules and wait for the next earthquake to open a new channel for nutrition.

"These things are on a long time basis longer than we're waiting for," said Lloyd.

There are still many questions. Among the most interesting, whether life was circulated down from the surface or grew up from below.

"Given that the energy and coal sources that are essential for carrying life in the deep open, and most of our history include a very tough surface world, it is reasonable to give his opinion that his / her life came from the exile and moved up, "Lloyd said.

The same settlement applies to other planets, Sherwood Lollar said.

"If we go to other planets, life can sound up loud. But there may be chemosynthetic life," she said.

"This is a part of the purpose of investigating life on other planets such as these deep deep habitats on this planet."

Rarely a scientist can help to & # 39; showing a new perspective on life, Lloyd said.

"We think we handle … in general. Then everything will be thrown out of the window. Every time we take, we're getting a" find that there is so great astonishment in the nature of our resources. "
