That article is very.........
I think it would be exciting to be in the laboratory when when a spherical blob of matter diverged into two spherical blobs of matter, sure. But, without being a scientist myself, I think that the scientist described in the article is jumping the gun if he actually claimed to have discovered something akin to a life form. It sounds more like a "bubble" than a "cell". Is a rain drop "reproducing" if it breaks into two rain drops? It hasn't replicated any information. If it doesn't replicate information, then how can it evolve?
In order for there to be life, there would need to be some kind of internal structure or information system that can reproduce itself. As far as I know, plasma cannot provide this because it does not allow for any chemical interactions or bonding. It is, and always will be, a homogeneous swirling mass of particles.
If there were non-plasma dust particles inside of the plasma, then the plasma might be able to work as a catalyst for chemical reactions and organization. It could be like the cytoplasm inside of a cell, allowing for life without water. That is a far more interesting thought not mentioned in the referenced article.
Boiling the problem down to it's most basic premise... life is a system by which matter can be assembled into complex, self-replicating structures. You might think of it as a computer that runs on chemical reactions and molecular sized mechanics rather than circuits and transistors. It requires software (DNA) containing information on how to replicate those structures (including itself) and hardware that is able to read and follow those instructions.
Despite the stigma attached to any anti-evolutionary sentiment, it remains a legitimate philosophical question as to whether the hardware needed to synthesize DNA AND the DNA needed to synthesize the hardware can both simultaneously apparate out of exited particles. One of many mysteries of science.
