  • Unlike your analogy, many aspects of DNA are not seperable. There isn't necessarily a sequence of DNA that accounts for every feature (most features?) that we may want. Anything as complicated as DNA is non-linear -- small changes in source can result in large changes in result, and we cannot necessarily deduce from a fixed number of known source->result mappings what all combinations of source will do.

    Only with models of what DNA actually does could we (maybe) figure this out. Right now the theory is mostly experimental -- knowledge that when people have done one thing, something else has occured. That's very crude.

    An historical analogy might be with semiconductors. Semiconductors are not very complicated -- you add some cyanide to silicon, I believe, and you have a semiconductor that can act as a transistor. But no one thought to do this until their was a model (with quantum mechanics) that would imply that such a combination would have useful behavior. There's no quantum-level manipulation involved in making semiconductors, only quantum-level understanding.

    In the same way, we may be able to do nearly everything we'd want to just by manipulating DNA. But we have to understand more than DNA to accomplish what we want.

    Hmmm... to explain the nonlinear part: say we have an original DNA sequence of AA (this is entirely abstract). Once you find out what BA and AB do, you may still have no idea what BB does. Understanding what each isolated change does may not give you any understanding of what changes do in combination. To figure out what A and B mean is in many ways simply to figure out how to predict what they will do in combination. And DNA has so many possible combinations...

  • And if it breaks and leaks everywher you have to sort it out ... gives a whole new meaning to the word 'patch'.

  • The tools of biotech are very crude, like chopping away with bronze axes. It's not possible to modify organisms by mixing and matching the parts we understand in UNIX-style.

    I don't know about that, necessarily, depends how you look at it:
    grep fluorescent_green_protein_gene JellyFish >> bunnygenes; cat bunnygenes > bunny_egg_cell; cat bunny_egg_cell | mama_bunny > glowing_baby_bunny. [ekac.org]

    Like the "core" Unix tools, our existing biotech tools ARE very "low-level", as you point out. We're certainly quite some way from the biotech equivalent of "higher-level" mix-and-match projects like php-gtk, but we've got some very useful building blocks to work with...including the project that is the subject of this article, which appears to be intended for building simulations of larger biochemical pathways...the next stage of biotechnology which we can't yet do much of, as you say. Sadly, this means I'm still probably at least a decade away from taking over the world with an army of Atomic Mutant Zombie Clones®

    Incidentally, I'd be willing to bet that a determined and/or skilled individual can do a LOT with a bronze axe...but I think one level of analogy is plenty, so I'll avoid belaboring the point. Besides, I understand what you mean: Hype bad. Results good. :-) .

    I'm not quite sure what you're getting at here. If you mean we don't have more than a blurry understanding of chemistry involved in the proteins that are encoded in the DNA, you're absolutely right. It almost sounds as though you're implying that we don't know what DNA "does" at all, though, which is obviously not true. We know EXACTLY what expressed DNA "does" - it codes for proteins. We also know exactly what the translation of DNA-base-pair-triplets to amino acids is. Noncoding sections of DNA are obviously trickier, but some of them are reasonably well understood now as well (e.g. promotor sequences, binding sites for repressor proteins, etc.).

    To figure out what A and B mean is in many ways simply to figure out how to predict what they will do in combination. And DNA has so many possible combinations...

    I can hear the original poster hopping up and down with agitation at the DNA-centric message here even as we type :-)
    The original poster's central [and correct!] point was that from a "functional" point of view, protein chemistry is more important than raw DNA, which I THINK is what you're getting at (if "A" and "B" in your example represent sequences coding for two separate proteins [or parts of one protein complex, like hemoglobin])

    To clarify my analogy, I'm thinking of DNA as the "at, tr, grep, and cat" (ATGC, get it? Sorry, couldn't help myself. Watson and Crick made me do it...) of biology, compared to protein chemistry's "Xfree86, Mozilla, Sendmail, and Koffice". My point was just that while the tiny utilities are just a meager bit of the more broadly useful and complex applications, they are still extremely useful themselves, just as the DNA data available is itself of great (but very focussed) usefulness, even before we have better knowledge of the protein chemistry later. (we don't understand the source code well enough to sit down and rewrite XFree86 from scratch, but have a pretty good understanding of many of the little subroutines and how they might be put together into new "proglets"...)

    Rating the advances in biotechnology simply by looking at DNA sequencing improvements is not very smart..

    Definitely a good point, but I wouldn't underestimate the usefulness of simply being able to sequence better.

    DNA Sequences alone can be/are useful for a lot of different research. Archaeologists and Anthropologists can use DNA sequences to help determine, for example, the relationship of one population to another and/or help trace migration of a population. Medical types can not only check for genetic diseases, but could also use DNA sequences to quickly check the identity of a pathogenic organism, if the sequencing technology becomes readily available enough. (Running a few PCR cycles is still much faster than trying to isolate and culture a pathogen from a swab). Zoologists and Paleontologists can use DNA sequences for similar purposes to what I mentioned for anthropologists and archaeologists, and can be handy for environmental research.

    Until we understand the *function* of the proteins that are derived from these genes, all biotechnology can do is recombine the already existing technologies.

    Again, this is true...but don't forget that "recombining already existing technologies" can be pretty powerful and useful all by itself. (Heck, "recombining existing technologies" is, basically, a fundamental design principle of Unix-based systems, isn't it? I know MY Unix-based systems are extremely useful... I love my "|" key...)

    I'm confident we'll be getting plenty of use out of DNA while we work on the harder problems of protein functions and chemistry

    P.S. Thanks for reminding me...I've been meaning to download the folding@home [stanford.edu] client and throw some of my meager computing resources at helping out...

    Remember, DARPA are the folks who came up with DARPANET, which begat the Internet, which begat the Web, which begat /. and many other wonderful things. Mindless paranoia just because the military is involved would mean turning our back on a whole lot of very cool things. And when it comes to biotech, it's not just cool; it may very well be the thing that saves your life somewhere down the line. (In a related vein, e.g., anyone who's been in a serious accident any time in the lastt few decades has the military to thank for their care, because the modern EMS system is the direct descendant of the military medevac system, which was first developed in its modern form in Korea and was perfected in Vietnam.) Yeah, it's perfectly reasonable about the government doing Eeevil Things with the knowledge -- but on the whole I'm a lot _more_ worried about cancer and diabetes and heart disease and AIDS and all the other killer diseases which may be cured with the knowledge this project creates.

    Also, as a former military medic (and current biotech worker) I can tell you that the military is often _directly_ interested in doing good things for people, not just seeing spin-off benefits (e.g., the way the personal computer can trace its lineage directly back to NASA and the USAF.) The military population -- active duty, retirees, and family members -- constitutes a large, diverse patient population with health problems ranging from arthritis to (obviously) bullet wounds. DARPA, USUHS, and other military research institutions have a strong and legitimate interest in medical advances -- which will first help soldiers, and then their families, but which will inevitably propagate to civilian medicine as well.

    A better analogy for the current state of biotech would be we can see the source code (by sequencing), we only understand a bit of the language (sometimes we can't tell the comments from the code, like obfuscated C), and we have the technology to cut-and-paste a statement or two within and between programs (recombinant DNA technology).

    SPICE [penzar.com] is a circuit simulator used by the EE types to design circuits.

  • As someone who is reasonably well conversant with this field (I've read many of the biological modelling papers, and heard Adam Arkin speak twice), I thought I would try and explain what's going on here. The DARPA call for proposals seems to contain two items - one on DNA computing and one on BioSPICE. As far as I can tell, they are two separate things. BioSPICE is an attempt to make a piece of software to model biological systems. It has everything you would expect: synthesis of RNA from DNA, translation of RNA into protein, chemical reactions, interactions, and so on. The goal is to use this software to model biological systems. The benefit of this is two-fold: one, you can test an existing biological system to see if the model agrees with the data; two you can use it to design new systems. However, the technology is very primitive. The only system that's beem modelled with any confidence is a piece of the phage lambda decision making circuitry (phage lambda is a virus that infects E. coli). There has also been some modelling of the cell cycle (the timing of DNA replication and cell division, but that was done more phenomenologically). As far as building novel biological circuits, this is still in its infancy: the only two things that have been built (both in the last two years) have been a flip-flop and an oscillator. So biology has a long way to go before it even gets to where electronic circuits were in the 40's.

Analyze the florescence on the DNA chip vs your test DNA or RNA and you know its information content - no destruction necessary.

    Beyond that, it is incredibly simple to produce limitless copies of any DNA or RNA you are interested in (PCR/RT-PCR, subcloning).

These include rapid prediction of the impact of external agents and environmental factors, and quick identification of targets and design of intervention mechanisms." -- now does this sound much like the human brain?

    We will not advance in understanding biology by simply looking at genes. That is like deciphering german ENIGMA codes, only to find out that you don't speak german. At the moment the advances are made in protein function (very difficult, and relatively slow progression).
    Until we understand the *function* of the proteins that are derived from these genes, all biotechnology can do is recombine the already existing technologies.

  • The fact that they are trying to do this is just a little disturbing. Maybe i'm just being paranoid, but i don't want ANYONE, much less anyone involved in our miltary, which serves as a model for narrow-mindednes and hypocrisy everywhere, playing with my biometrics the way i play with pcbs. Who do they think they are to be playing with biocircuitry?
  • I don't think this is a good idea for mankind.

    Humans have evolved into what we are over hundreds of millennia, and artificially tampering evolution could have potentially catastrophic consequences.

    I know it's a worst case scenerio, but imagine a future where normal, unmodified humans are considered to be an inferior waste product of the technological revolution. Imagine a world where the richest members of society are genetically modified with superior DNA and circuitry, while those of us who choose to keep our existing god-given bodies are reviled and treated as second class citizens. Adolph Hitler experimented with similar body modifications in his quest for racial purity and superiority, and we all know the results of that little endeavor.

    I think that technology is wonderful for the advancement of humanity, but it needs to be kept seperate from biology. We need to keep our bodies the way God and nature intended them to be, and cease this senseless quest for an Arian race. If we do not, the consequences could be catastrophic.

  • Relax, this is open source genome hacking. You simply take their modifications, add a few of your own tweaks to make your own super soldiers. Maybe give them some of those funky regenerative characteristics of a starfish so when they get blown apart they regenerate themselves, or the hearing capabilities of a dog so you can speak with at a frequency higher than the hearing range of "normal" humans. Or even make them hermaphrodites so you don't need to make two different types to have a sustainable population.

    Of course, you do the last suggestion, I'm not responsible if you make them overly horny and have them take over humanity thanks to their exponential birth rates.

  • Hrmm...the millions of years of evolution that created human beings also caused species to become extinct. Think of the Neanderthal, Australopithicus, Smilodon, all of which once represented the pinnacle of evolution, and all of which became extinct. What makes you think humans are all that much different?
  • I was thinking of all this bio tech. and came to a conclusion. When your working at home for some major corporation and all of sudden your computer gets sick, Does the company hold you responsible. After all one would think Bio tech would be subceptible to virii as humans are. Any one have any thoughts about this.

  • Think about it. With this sort of development you can use the programs to deliver target drugs to specific areas in the body with accuracy. But it can also be used to program billions of little machines to destroy DNA. It is unfortunate that developments that can benefit mankind can also be used to attack it.
  • read How the Leopard Got its Spots - the author details this beautifully (chaos theory and biology hand in hand) when they start understanding and utilizing protein sequencing techniques, then we should be Gattaca-paranoid.
  • I was having a little jibba-jabba with Mr. T the other day. He said, "Oh, I hack humans with the best of 'em! And I pity the fool who don't!" JIBBBBBBBAAA-JABBBBBBBBBA Lovingly yours, Mrs. McCheese
  • This gal knows what she's talking about! If I wasn't the same person who posted, I'd say it was monkey trash but since I am, I love it! Sincerly your, Mr. T
  • When you say "the only system that's been modeled with any confidence", I'll assume you are talking about Arkin's work. There's a good bit of work going on this area. And not all of it is academic. There are companies building systems to model cells, tissues, diseases, etc. The goal is to help pharma companies come up with better drugs and spend less money doing it (e.g., fewer failed drugs, dead ends).
