I remember, a year or two ago, reading about a group which were simulating the early times of earth's creation and they wanted to see whether life naturally pops out in it. But now I can't find it again or any other news from that group. Does anyone know about such a simulation?

The only thing that I'm aware of without Googling for it is Stanley Miller's experiments back in the 50's.

It wouldn't surprise me at all if someone is doing it; I just haven't heard of it. It seems like a job that BOINC should take on for "distributed computing" (I work on SETI, Einstein @ Home, a global climate model, and about 4 other projects). In fact, maybe they have taken it on and that's how you learned of it. I haven't checked what they're up to recently because the stuff that I'm already doing is demanding enough.

edit: corrected a name

Another question. How amino acids can form life?

With the help of fatty acids. The subject is called abiogenesis. Skip to 3:48 for the good stuff

As to your original question, I hadn't heard of it, but doing some googling, I found this paper that models abiogenesis in terms of fuel cells, which is an interesting idea:


I also found this press release about using supercomputers to simulate abiogenesis:


Here's the actual research:

While reading through an article at C&EN, I think I found the study you're looking for:
Wang et al. 2014. Discovering chemistry with an ab initio nanoreactor. Nat. Chem 6: 1044. http://dx.doi.org/10.1038/nchem.2099 [Broken]
Chemical understanding is driven by the experimental discovery of new compounds and reactivity, and is supported by theory and computation that provide detailed physical insight. Although theoretical and computational studies have generally focused on specific processes or mechanistic hypotheses, recent methodological and computational advances harken the advent of their principal role in discovery. Here we report the development and application of the ab initio nanoreactor—a highly accelerated first-principles molecular dynamics simulation of chemical reactions that discovers new molecules and mechanisms without preordained reaction coordinates or elementary steps. Using the nanoreactor, we show new pathways for glycine synthesis from primitive compounds proposed to exist on the early Earth, which provide new insight into the classic Urey–Miller experiment. These results highlight the emergence of theoretical and computational chemistry as a tool for discovery, in addition to its traditional role of interpreting experimental findings.
