Synthetic Biology May Spawn Biohackers

nusratt writes "EE Times reports 'Design automation systems tailored to the task of genetic engineering . . . can lead to the accidental or deliberate creation of pathogenic biological components.' Design of molecular machines is analogous to doing system-on-chip work, and hackers 'will not need a detailed knowledge of biochemistry to effectively create complex biochemical machines.' A Harvard genetics professor says, 'Even if we don't have bioterrorists and teen-age biohackers, we will still create things that do not have the properties that we thought they would . . . Even if you are genetically resistant and recently immunized, you will have problems with artificial biological agents.' He also says that there are two big differences between this risk and nuclear weapons: (1) building weapons is harder; (2) synth-bio work is more accident-prone. Oh great, just great: script-kiddies with smallpox . . ."

    Even with a 'designer' bio-machine, the components will be similar/identical to already existing ones in normal life-forms. We know just how adaptable life can be, so even an unintentional slip-up could produce a noxious result :-(

    The problem is that a nuclear weapon needs an enormous number of things to be 'just so' before it'll go bang. You may be able to bodge together a 50% solution far easier when your building blocks are so much more adaptable...

    To draw a parallel with FPGA's, it's relatively easy to write a few hundred lines of verilog, which synthesize the gates wthin the adaptable fabric of the FPGA into a 60-80% solution. The hard bit is squeezing the last nanoseconds out of the device using technology mapping and hand-placement.

    The creation of tools to make bio-machines similar to verilog/VHDL would indeed potentially have grave consequences, but I can't see it going any other way. In both cases (Biology & chip-design) you have an enormous task to create something from scratch (enzymes/bases for biology, LUTs/LC's for FPGA's), so you write a description language and model in that instead. Far far simpler once you can map from the description to the reality...

      there's a really good reference on the human immune system here at http://uhaweb.hartford.edu/BUGL/immune.htm

      The two really interesting parts are the adaptive immune system where there are the cell mediated (killer T-cell) and humoral (antibody) immune responses.

      Both use the principle of making molecules that will stick to bad molecules, and if they do triggering a cascade of events that eventually winds up destroying the bad molecule and the things affected by it, and leaving healthy tissue behind untouched (we hope).

      The really really good part is that you're right, if the viral coat proteins have the same chemical surface at specific regions called epitopes, then the same antibodies will be able to bind all of them, even if they're different in other places.

      Most molecules have several epitopes on them, although sometimes you have to bind most or all of these before a response is raised.

      Viruses in the wild beat this by mutating every time they reproduce inside a cell by using error prone replication techniques. After all, if you make a billion particles and only 2% work, you can still infect your next host quite smartly.

      That means that two individuals with the same disease, one catching it off the other, might have sufficiently different viral particles that an immunisation against one set of epitopes is ineffective. That's what happens with the common cold.

      If all you have is a hammer..

      Sorry, but this analogy is weird. Biology does NOT follow any simple rules of logic. In fact, we don't even know the rules.

      A DNA sequence maps to an amino acid sequence, we've got that part pretty well figured out.
      The AA sequence maps to a protein or peptide. Right there, we're screwed. There is no ab initio method which accurately predicts protein folding. There are no reliable empirical methods either.

      You can't really rely on existing structures for predicting new ones either; Even a single mutation can give you a completely different structure. (Compare an ordinary hemoglobin to a sickle-cell mutated one)

      Ok, but just assume we can find out the structure, how do you determine the function of that protein?
      Again, there is no method of doing that. There is an entire world of chemistry which can go on. And in the enzymes for which we know the structure and function, there are a huge number in which we still do not know the mechanism. If chemistry was easily predictable, there would be far less for chemists to do!

      Given you know the function of a single enzyme, can you predict how it will interact in a complex biological system with millions of other proteins, organic substances and whatnot?

      There is no room for making the kind of abstractions which are done in the world of computers and engineering. Things are far more complex, and what is worse, they are not self-contained.

    The point was that it was slow, laborious work with lots of hardware support (agar, incubators, restriction enzymes, etc) needed and a danger of getting various sorts of stuff on yourself. And we're still (sadly) profoundly ignorant of what really makes bugs tick...

    I agree once you have a virus or some time of self spreading destructive agent, it is easier to spread than tradional bombs. Building tailored geneic machines will be like every other process. It won't be very profitable until some big break through makes it cheaper for certain apps. Then we'd carelessly use the tech for 5-10 years without any problems then one day we'd have an accident and the news folks would be all over it. There would be all sorts of safe guards so that nothing like that could happen again.

      It's a clever concept, but man does Crichton's execution suck. His earlier work is vastly superior, both from a technical standpoint, and from the standpoint of quality of writing. Jurassic Park had a few plot holes, but he's been getting sloppier ever since. He's also abandoned any concern for scientific credibility.

    This kind of threat is why the Europeans are so freaked out by GMO foods. In any event, genetic engineering will change our lives in ways that we can't predict. Life today is quite different from what the futurists were predicting in the 1950's. Just go down to the library and drag out some old editions of Popular Science.

    Creating mass havoc is usually harder than it looks. Consider the terrorists that used nerve gas in the Tokyo subway. If you had asked me, I would have guessed that letting off nerve gas in such a location would have killed thousands. It didn't quite work that way.

    I'll assume that your massive breeding ground for HIV is "All of Humanity."

    The one thing about HIV is that it's very succeptible to oxidation. Any kind of oxidising agent, like bleach or strong disinfectants or even some mouthwashes, will render a puddle of HIV infected blood safe to clean up within minutes. Faster if you mix it, but please dont.

    To get airborne, the HIV would first need to borrow some viral trickery from other diseases to reproduce in the lungs and mucous membranes as well as its usual home of in the lymphatic system, and then once expelled on a person's breath it would need a new coat to protect it from the toxic levels of oxygen in the air.

    All this, while keeping the size of the genome down to a managable length so you can stuff it into its protein coat.

    If you can engineer both those capabilities into HIV, you would have Airborne AIDS. Quite a puzzle though.

    I wouldn't worry too much yet. IMO the article reads like a FUD/Science Fiction cross.

    So what if the circuit designers don't need to know all the physics behind what they're doing. They do need expertise in circuit design. In fact it amazes me sometimes how many people doing molecular biology don't even understand the chemistry behind what they're doing -they just follow the recipe. They do, however, know how to "design" what they're doing.

    Yes, many proteins have a somewhat "modular" structure, but just sticking these "modules" together is most likely going to give you a misfolded protein that does nothing but get immediately degraded or end up in the cellular equivalent of the junk heap (if it doesn't kill the cell expressing it first).

    There's all kinds of information in the article that IMO sounds much scarier and easier to do than it really is. From my vantage point it seems like it would be much harder to build a single working protein from pieces than to build an atomic bomb. It can take months to engineer a simple mutations and get a protein that's properly expressed.

    Considering how much hard work it takes for experts, using very expensive equipment an reagents to do this kind of thing, I'm not too worried about BioHackers quite yet.

    The problem with all this isn't so much the creation of new, deadly pandemics -- nature does a good enough job of that. The real problem is the way amplification of international transport has been behind almost every major pandemic from the Plague which followed on the heels of the Mongol Empire's wide stretch -- to the pandemic of the first World War.
