    Scientists Take First Step Towards Creating 'Inorganic Life'

    ScienceDaily (Sep. 15, 2011) — Scientists at the University of Glasgow say they have taken their first tentative steps towards creating 'life' from inorganic chemicals potentially defining the new area of 'inorganic biology'.

    Professor Lee Cronin, Gardiner Chair of Chemistry in the College of Science and Engineering, and his team have demonstrated a new way of making inorganic-chemical-cells or iCHELLs.

    Prof Cronin said: "All life on earth is based on organic biology (i.e. carbon in the form of amino acids, nucleotides, and sugars, etc.) but the inorganic world is considered to be inanimate.

    "What we are trying do is create self-replicating, evolving inorganic cells that would essentially be alive. You could call it inorganic biology."

    The cells can be compartmentalised by creating internal membranes that control the passage of materials and energy through them, meaning several chemical processes can be isolated within the same cell -- just like biological cells.

    The researchers say the cells, which can also store electricity, could potentially be used in all sorts of applications in medicine, as sensors or to confine chemical reactions.

    The research is part of a project by Prof Cronin to demonstrate that inorganic chemical compounds are capable of self-replicating and evolving -- just as organic, biological carbon-based cells do.

    The research into creating 'inorganic life' is in its earliest stages, but Prof Cronin believes it is entirely feasible.

    Prof Cronin said: "The grand aim is to construct complex chemical cells with life-like properties that could help us understand how life emerged and also to use this approach to define a new technology based upon evolution in the material world -- a kind of inorganic living technology.

    "Bacteria are essentially single-cell micro-organisms made from organic chemicals, so why can't we make micro-organisms from inorganic chemicals and allow them to evolve?

    "If successful this would give us some incredible insights into evolution and show that it's not just a biological process. It would also mean that we would have proven that non carbon-based life could exist and totally redefine our ideas of design."

    The paper is published in the journal Angewandte Chemie.

    I have a few remarks:

    Why would a Glaswegian prof publish in a non peer-reviewed journal named Angewandte Chemie (could be translated as either Applied- or Practical-Chemistry), when there are several top peer-reviewed UK journals in the field? This smacks of rejection in these (my speculation). Also this is in the stages before vapourware. At the best it is, at this stage, pure speculation without a base for hypothesis.

    There are 10 named authors of the paper, mostly Japanese. Looking through his bio, Prof Cronin has not been the lead author of many of the 200 papers he mentions. Recently, he has been the sole author of a paper L. Cronin, 'Defining New Architectural Design Principles with 'Living' Inorganic Materials.' Archit. Design. 2011, 34-43, Abstract:

    At the University of Glasgow, Leroy Cronin is leading a group of scientists that are pioneering the engineering of a fundamentally new approach to building materials, which scales up from the nano scale to the micro. Cronin reflects on the possibilities of this new paradigm that gives inorganic cellular materials the potential to be ‘programmed’ to sense environmental changes, generate power, self-repair, shift properties and even compete with other building materials for resources.
    His self-proclaimed interest is presenting science to the public and I believe he has most probably achieved this aim in trumps. This is excellent in itself and he founded the world-wide Cronin Group of researchers. Notwithstanding, I'm not sure that he, himself, does much research and that he may be living on the back of others (again, my speculation). I knew very well a prof. like that at the Swiss Federal Institute of Technology, Lausanne and his actions have sensitised me to this kind of thing.
