anyway, its not really a cell cos it doesn't have DNA. It sounds more like a really cool chemistry experiment to me.
You should read the details of the New Scientist article as it goes in to detail about that…
"Cronin's bubbles are never going to be truly life-like until they carry something like DNA to drive self-replication and evolution"
They do not contain DNA but he "could get polyoxometalates to use each other as templates to self-replicate." The follow paragraph is also very exciting at even the faintest possibility of evolution sans DNA.In an ambitious seven-month experiment, Cronin is now mass-producing bubbles and injecting them into an array of tubes and flasks filled with different chemicals at different pH levels. He hopes that the mix of environments will allow only the fittest bubbles to survive. "If the pH is too low and [some bubbles] dissolve then those droplets will have died." Others may persist and accumulate. In the long run, the real test will be whether the cells can modify their own chemistry to adapt to different environments. Cronin hints that his latest work may show this, but is unwilling to give details as yet. "I think we have just shown the first droplets that can evolve" is all he will say.
In any case the entire project is super fascinating…
