In summary: This is the first time someone has seriously shown the possibility and likelihood of these structures existing. These complex self-organized plasma structures exhibit features normally attributed to living matter such as self-duplication and metabolic rates. They may qualify as candidates for inorganic living matter in space under certain conditions.

In this month's "New Journal of Physics" we find an exciting paper on the possibility that space is filled plasma-based forms of, well, "life". Or as Bones said to Kirk on "Star Trek", "Its life, Jim, but not as we know it." I know that people have loosely speculated on plasma based forms of life previously, but as far as I know this is the first time someone has seriously shown that it is possible, and perhaps very likely. More problematic is what we should call these dynamically evolving plasma structures. In the present form they seem to exist in the ill-defined regions between "certainly living" and "certainly not living", like viruses.

From plasma crystals and helical structures towards inorganic living matter

V N Tsytovich, G E Morfill, V E Fortov, N G Gusein-Zade, B A Klumov and S V Vladimirov

Abstract
Complex plasmas may naturally self-organize themselves into stable interacting helical structures that exhibit features normally attributed to organic living matter. The self-organization is based on non-trivial physical mechanisms of plasma interactions involving over-screening of plasma polarization. As a result, each helical string composed of solid microparticles is topologically and dynamically controlled by plasma fluxes leading to particle charging and over-screening, the latter providing attraction even among helical strings of the same charge sign. These interacting complex structures exhibit thermodynamic and evolutionary features thought to be peculiar only to living matter such as bifurcations that serve as `memory marks', self-duplication, metabolic rates in a thermodynamically open system, and non-Hamiltonian dynamics.

We examine the salient features of this new complex `state of soft matter' in light of the autonomy, evolution, progenity and autopoiesis principles used to define life. It is concluded that complex self-organized plasma structures exhibit all the necessary properties to qualify them as candidates for inorganic living matter that may exist in space provided certain conditions allow them to evolve naturally

Thanks, Robert. Ivan (I think) posted a link about this in Biology, but it was more of a 'Popular Science' feature. A lot of us have been hoping for a more detailed examination.

I'd like to bump this thread to include a link to the illustrated full text of the Tsytovich paper referenced above:
http://iopscience.iop.org/1367-2630/9/8/263/fulltext

Along the same lines, I found this similar but earlier article: http://www.dapla.org/pdf/Lozneanu1.pdf [Broken]
"Thus, similar to biological cells, the boundary of a self-assembled gaseous cell provides a selective enclosure of an environment that qualitatively differs from the surrounding medium. The boundary appears as a spherical self-consistent electrical double layer (DL) able to sustain and control operations such as: (i) capture and transformation of energy, (ii) preferential and rhythmic exchange of matter across the system boundary and (iii) internal transformation of matter by means of a continuous ‘‘synthesis’’ of all components of the system."

And from my own backyard,

A recent video lecture on Water, Energy and Life by University of Washington Professor Gerald Pollack. I hope the 60 minutes or so you spend watching this proves to be well justified. New laboratory experiments are shown.

Respectfully submitted,
Steve

I find this research to be incredibly intriguing and groundbreaking. The idea of inorganic life forms challenges our traditional understanding of what constitutes life and opens up new possibilities for the existence of life beyond our planet.

While the concept of plasma-based life forms has been speculated before, this is the first time that it has been seriously studied and demonstrated to be possible. The fact that these structures exhibit features normally attributed to organic living matter, such as self-organization, evolution, and metabolic rates, is truly remarkable.

The authors raise an important question about what to call these plasma structures - are they living or not? It is clear that they exist in a gray area between traditional definitions of life, much like viruses. However, the authors make a compelling argument that these structures possess all the necessary properties to qualify as inorganic living matter.

The implications of this research are vast and have the potential to greatly expand our understanding of the universe and the possibility of life beyond Earth. Further studies in this area could also shed light on the origins of life and the potential for life to exist in extreme environments.

I am excited to see where this research will lead and how it will shape our understanding of life in the universe. It is a reminder that as scientists, we must always be open to new ideas and discoveries, even if they challenge our current beliefs.
 

1. What is inorganic life?

Inorganic life refers to living organisms that are not composed of organic compounds, which are the building blocks of traditional life forms on Earth. These organisms may have different chemical compositions and may not require the same conditions for survival as organic life forms.

2. How is inorganic life different from organic life?

Inorganic life differs from organic life in its chemical composition, as well as its ability to perform the biological processes that are essential for life. While organic life is based on carbon and requires water and a specific temperature range for survival, inorganic life may be based on other elements and may thrive in extreme environments.

3. Is there evidence of inorganic life on Earth?

While there is currently no definitive evidence of inorganic life on Earth, some scientists have proposed the existence of potential inorganic life forms, such as mineral-based organisms living in deep-sea hydrothermal vents. However, further research and evidence is needed to confirm the existence of inorganic life on our planet.

4. Is inorganic life possible on other planets?

It is possible that inorganic life may exist on other planets or moons in our solar system or beyond. The discovery of extremophile organisms on Earth, which can survive in extreme conditions, has expanded our understanding of where life could potentially exist. Future missions and research may provide more clues about the existence of inorganic life in the universe.

5. How would the discovery of inorganic life impact our understanding of biology and the search for extraterrestrial life?

The discovery of inorganic life would greatly expand our understanding of biology and the potential for life to exist in different forms. It would also open up new possibilities for finding extraterrestrial life beyond our traditional definitions of what constitutes living organisms. This discovery could also have implications for how we search for and identify potential life on other planets and moons in the future.
