Methane life on Titan simulate by scientists - VIDEO PDF Print E-mail

A new type of life forms based on methane and used in his life activity of oxygen, but with the metabolism and the ability to reproduce itself, was modeled by the research team from Cornell University, USA.

In the new study, chemical engineers and astronomers have proposed the concept of the cell membrane, consisting of small molecule organic nitrogen compounds and capable of operating at temperatures of liquid methane, which can reach -180 degrees Celsius.

Life on Earth based on phospholipid bilayer membrane forming a durable, water-permeable, and many other substances dissolved in the vial, wherein the organic material entered each cell. Such a vial from the cell membrane is called liposome. Therefore, many astronomers are looking for extraterrestrial life in the so-called "habitable zone" around the Sun, where water can exist in liquid form. But what if the cellular activity is based not on the water, and methane, which has a much lower freezing point?

Chemical engineers have named their concept of the cell membrane "azotosomoy." "Azotosoma" consists of nitrogen, carbon and oxygen, which are known to be present in the seas Titan. This cell membrane showed during the session of computer simulation are the same stability and flexibility, as in liposomes terrestrial life forms. As the basic substance of the chemical compound "azotosomy" scientists acrylonitrile was selected, the methane molecules in the medium which can be connected to the membrane-like structure. The presence of acrylonitrile - a colorless toxic organic compounds - in the atmosphere of Titan was previously installed securely.

The next stage of their research, the authors see a detailed study of the behavior of cells with nitrous membrane in liquid methane.

The study was published in the journal Science Advances.
