    When you select for resistant bacteria growing in the presence of antibiotics, there is usually a fitness tradeoff for that resistance. Suppose now instead that we have some virus-resistant organism we've engineered. This means all the virus receptors on the surface of the cell no longer bind virus particles, and if you've done this for *many* virus receptors, then you've mutated a lot of cell-surface proteins. I can't imagine this would go without fitness cost.

    On the other hand, from studying influenza I can say that viruses evolve much faster than we do and if a variant (maybe adapted to another host) or subtype emerges that can bind your receptor anyway, then in effect you've selected out variants but not stopped the virus. Getting regular vaccines are still the way to go on this, IMO.

    This article is hyped up to the stars.

    It's good work, but the ideas aren't "revolutionary" the way they are portrayed.

    Lateral gene transfer in bacteria has been known for a long time. It's how resistance to antibiotics is spread among bacteria for example.

    It's also been used a good deal already by microbiologists/biochem types (that line is getting a little blurred these days).

    Church's group has found a way to automate this.

    They can create large numbers of bacterial strains which have some or all of the desired characteristics in a short time.

    The downside is the needle of the desired organism is in a haystack of partially successful or unsuccessful ones. In this case, it was linked to production of a bright red chemical. You could determine which was closer to the right one by color. That's easy to automate.

    Most characteristics won't be that easy to screen or automate.

    Church then goes into what's really an old idea. Encrypting the genome so that it's resistant to existing virus types. You then use a modified ribosome to translate that into proteins. I remember discussions of that in the late 80/early 90s on some of the transhumanist newsgroups (anyone remember usenet?).

    The devil in the details here is that much of the information in the genome isn't for coding proteins directly, but for regulating gene expressions and other purposes. Much of that latter we still don't understand. It's hard to design an encryption to preserve a functionality you don't understand.

    So, instead of throwing up their hands, Church et al appeal to using the above automated method and the microbes to sort out something that works, but again we really won't understand. At least at first.

    It's an interesting idea. Sounds like a lot of work even if automated.

    But, as anyone who was caught up in the genetic algorithms craze in computers can attest, it's not a guaranteed solution.

      Actually this research is really interesting...maybe not revolutionary, but interesting. I went to a talk by one of Church's postdocs at a conference recently and he was talking about this project. There are a lot of potential applications, but the example he was using was the optimization of the production of a metabolite. Traditionally this has been the hold up for synthetic biology. Getting microorganisms to produce industrially useful metabolites is not new. But engineering them to produce a large amount in and economical manner is where all the time and money goes because it requires some modeling, a lot of guessing, and mostly manual genetic manipulation. This technique uses the principal of directed evolution of a single gene (known for a few decades as you say) and applies it to an entire gene cluster, and potentially an entire organism. And it works! It's not a finished project, to be sure, but it can potentially become a very useful tool.

      The "encrypting the genome" case refers to changing the codon code for the organism. Non-coding sequences won't be affected by it. The idea is that if you use a non-canonical genetic code for protein expression, foreign dna can still be inserted into the genome, but it can't be expressed. So viruses won't be able to replicate in the organism. It is immunity of sorts, but perhaps not really the way we normally think about it. It is useful because it potentially allows for the creation of stable genetically-engineered organisms. The biosafety concerns of genetically modified organisms come from the various mechanisms by which recombinant dna can "escape" and get out into the environment. An organism like this will be genetically isolated and therefore should mitigate many of those concerns. It also lessens the likelihood of further mutation over time, which can make your possibly $millions investment worthless.

        The virii that target bacteria (phage) tend to hijack the existing stretches of dna that the bacteria themselves use for incorporating new dna. This makes sense, as it's less likely to disrupt something else if it lands in a pre-prepared area where the surrounding sequences are more of a known item.

      You could, you know. Granted the project to create immunity to prions would require modifying all the proteins to use different amino acids...

      I think that the project as stated is already too ambitious to succeed. What you're proposing would be an order or two of magnitude more difficult. ... But probably not much more than that.

      Also, I'm not sure just how much bacteria use prions. Mammals use lots of them, so we are subject to prion diseases, but bacteria use many fewer...I'm not certain they use any.

  • I wonder how long it will be before we have a genetically-engineered yeasts that produce THC, morphine, amphetamines, cocaine, etc., so that anyone could make what they want in a small Petri dish, starting from a microscopic amount of starter yeast. How would society deal with this?

    • Seems doable today, if you are willing to invesr half a house and a few years into it. Too bad most people wiling to invest those are looking for more usefull results.

    • Fyi, the genes responsible for synthesis of THC-a (carboxylated acid form found in plant before heating/burning/vaping/cooking which causes rapid decarboxylation to form THC), from acetyl-CoA is known and published, with the genetic sequences attached to the publication. It is in the 19 September 2009 publication of the Journal of Experimental Botany.

      Plasmid based expression, or transgenic expression, in yeast or E. coli, or tomatoes (no plasmid in tomatoes) would not likely require more than one dedicated

    • How would society deal with this?

      Probably by outlawing petri dishes and lab equipment. I can see the anti-freedom pro-drug war idiots now. "What legitimate use could someone have for petri dishes and lab equipment BESIDES making drugs?!"

    " to create an organism that is genetically immune to all viruses."

    And hungry. Very, very hungry. With the ability to smell neurons.

  • There are potential dangers in making organisms virus-proof, though. Most obviously, they might have an advantage over competing species if they escaped into the wild, allowing them to dominate environments with potentially destructive effects. In the case of E. coli, those environments could include our guts.

    "We want to be very careful. The goal is to isolate these organisms from part of the natural sphere with which they normally interact," says Carr. "We shouldn't pretend that we understand all possible

    • Is PlantStudio still being developed? I occasionally have to do botanical illustration and have stumbled across PlantStudio before, but never evaluated it. Cheers, Craig

      • Thanks for asking. I ported part of it to Python (to try on the OLPC, which was slow), and part of the overall framework to Java (mostly for StoryHarp), but there has not been a new version in a long time, sorry. It still works under Windows emulators; use the zipped version as the later versions of Windows don't like the installer. A free registration code is on the site.

  • First off, to make an organism that is impervious to virus is probably impossible. But assume that you could. WOuld that be a good thing? Nope. It stops evolution. Evolution is NOT single point genetic mutations, but is virus splicing/slicing in new sections, possibly even new genes. However, even if now sections, these will ultimately make it to the point of being a full gene.

  • It's easier to list the things that could not possibly go wrong.

  • An analogy would be that they are building a Z80 processor, in a world all viruses run on Intel. None of the opcodes from the virus would work.
  • One of the best short stories from the master himself -- Theodore Sturgeon. This article reminds me of it. I should read it again.

  • What we have learned so far from all the sci fi movies, if anything, is that when you develop something that is immune to viruses, you develop a Frankenstein, and then you will suffer even greater then the good it could have provided...please stop searching for immunity, that is the whole reason why life is precious, by making everyone immune to everything, then life becomes taken for granted....
