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 . . ."

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).

    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.

    If you've seen some of my prior writings you may already know my opinions, as always I encourage replies and responses here or in private email, and if anyone believes this is a troll feel free to mark it and/or say so.

    In short:
    I think there are basically 2 competing concepts on how to handle this and similar problems.
    1. Heavily limit access to information, research, and experimentation.
    2. Free and open access to information, active support for open research and experimentation.

    I believe:
    The danger from nano/bio technologies is real.
    The dangerous time extends from now until the technology is mature.
    Restrictions to slow or halt this technology increases the danger period.
    Terrorist types are actively pursuing this technology.
    Terrorists gain more from increased time than from access to open research.
    Restrictions reduce the pool of skills and ideas available to deal with the danger.

    In more detail:
    As the subject line suggests, I don't believe we can shove this back in the box. In addition I don't believe that trying to limit or control the technology and it's distribution is going to be successful. While that process was affective (debatably as to how effective though) in limiting nuclear technology IMO because nuclear technologies require a large and very specialized heavy industrial base which in turn also required budgets that limited serious work to national sized organizations.

    This isn't true for bio/nano tech. Much of this work can and is being done on budgets that are easily in the realm of small companies, and even many individuals. Certainly within the grasp of those organizations we fear will be using it to harm us.

    Simply put, I believe that the knowledge is out there already. I believe that the more organized terrorist type groups are likely already pursuing these technologies actively.

    Now, if we pursue a path of limiting knowledge the results as I see them are 2 fold. 1. We will slow development of bio/nano malware (malevolent hard/soft/squishy ware) that the terrorist types are undoubtedly already working on. 2. We will stop development in all but a few officially sanctioned arena's. We will reduce by orders of magnitude the number of people who are skilled in working with these technologies. Additionally we will slow by a huge degree the overall advance of these technologies.

    I'm in agreement with those who believe that these technologies are extremely dangerous. My personal belief is we, as a intelligent species, have approximately a 40% chance of surviving the next 50 years. Where I disagree with many is that I believe those odds get much worse if we try to put heavy limits on knowledge, research, and experimentation. I believe that the more open and openly supported this technology is the more the odds improve.

    My reasoning is based on the following. I believe that if we start restricting knowledge dissemination, research, and experimentation then we will lose most of those who would have the skills, knowledge, and ideas that will be required to defend against bio/nano malware that will be released sooner or later. I don't think that any amount or level of restriction will stop organizations that are intent on using this to harm others. My belief is that all it will accomplish is to slow the development and ensure that the process's that are used by those working on malware are unique and only understood by the malware creators.

    In addition I believe that the danger is limited to the short period of time before this technology matures. I believe that giving malware developers more time is much more dangerous than the advantage they would get from open knowledge sources. The basis for this is my belief that a mature bio/nano technology will provide both personal and environmental monitors and defenses that will reduce the danger to a minimal scope and severity.

  28. Much much harder than that... by hung_himself · · Score: 3, Insightful

    Genetics is neither quick nor easy even if you know what you are doing and have lots of time and resources. There is essentially no hope of anything with a complicated set of changes surviving let alone do what you want it to do. That's why modifications are basically one gene at time - mostly one mutation at a time.

    The hacker analogy is having a billion lines of disassembled code which you barely understand. Random changes are just going to cause the program to crash. Geneticists basically only know the NOP command (ah those were the days using MACSBUG...). If you know where the branch point for a key subroutine was you might be able to shut it down or have it run another subroutine but that is still very difficult to do without crashing everything. Changing it to do something completely different is very very difficult since you really have no idea what the code does. Add to that the fact that you need a lab and weeks or months to introduce your changes and you can appreciate how far-fetched these fears of amateur bio-hackers are.

  29. Re:This will never happen, guys. by maximilln · · Score: 2, Informative

    I agree with your principles, however the following technical information is incorrect:

    Alanine is very small as far as molecules go; it's one of the 4 key blocks for DNA

    Alanine (which _is_ a simple molecule) is one of the 21 most common amino acids used to make peptides, enzymes, and proteins.

    You were thinking of Adenine (which is _not_ a simple molecule) which is one of the four DNA base pairs. Every sequence of three DNA bases translates into one amino acid at the ribosome.

  30. Viral replication is generally accurate by bradbury · · Score: 3, Insightful

    Actually the last statement is incorrect.

    The common cold is caused by Rhinoviruses which are a member of the family of picornaviridae (RNA viruses). The problem with rhinoviruses is that there are over 100 serotypes (sub-types) of the virus that have evolved over time. You do gain immunity to an individual serotype but you have would have to catch 1 cold a year for 100+ years before you were immune to them all. I can verify this -- I visited Russia a lot over a period of 5+ years. Whenever I went there initially I always got sick. But after several years I was able to go to Russia and return without that occuring. I presume this was because I gradually built up an immunity to all of the rhinovirus serotypes found in Russia but not in the U.S.

    Rhinoviruses do change over time but they do it by recombination (swapping genome fragments) to create new serotypes not by using sloppy replication. It should be kept in mind that viral replication (of non-DNA viruses) involves very simple replication strategy. The viruses do not have at their disposal all of the repair proteins (120+) that are found in mammalian DNA replication & repair. So their genomes will vary somewhat over time -- but not vary *that* significantly because a successful virus wants to make more successful (identical) viruses.

    Influenza (flu) on the other hand is a multi-chromosome virus -- it evolves by swapping chromosomes with influenza coming from other species -- human flu usually varies due to recombination of chromosomes between human, chicken/duck and pig influenza variants (commonly kept in close proximity in China).

    It is only retroviruses (e.g. HIV) that have a really sloppy replication protein and mutate at a very high rate.

    [This is based on my training in microbiology as well as some quick checks in "Fields Virology".]

  31. GMOs Are Our Salvation, Ignore The Luddite-Lobby by Vagary · · Score: 4, Insightful

    Forget biological WMDs, we have been under attack by chemical WMDs for decades. GMO food is the only reasonable* way to reduce pesticide use, which is actually causing health problems right now, as opposed to the vague danger of GMOs. Ingestion of weird DNA does nothing but entertain your stomach acids, so the only potential health threat is that GMOs may produce weird chemicals -- but surely they won't be as bad as the franken-pollutents in our environment right now!

    * I'd like to believe the claims that organic food can feed the world, but it's an extraordinary claim and I have yet to see even weak evidence.

  34. The point is obscured by generalizations by James+Turpin · · Score: 2, Insightful
    There are really 2 separate issues here:

    (1) People doing legitimate research that lead to benneficial treatments with unexpected side-effects. This happens already in medicine all the time. It's nothing new. The real problem here is that some of this stuff ends up becoming food, not medicine. It should be held to higher standard, because risky food is just not acceptable the way risky medicine is acceptable. But in many countries, such as the USA, its not held to a higher standard than drugs.

    (2) Evil mad scientists. Sure, somebody with expertise and resources could manufacture something pretty scary stuff in their spare time. Somebody could do gene splicing to make some bacteria or virus manufacture a toxin or narcotic that is typically only made by plants. Walla, you now have the means to convert sugar into THC. Or somebody could grow viruses in a culture of human cells (say, blood), then subject the viruses to oxygen. Repeat until you have viruses that survive in open air and thrive in the human body. Walla, air-born AIDS.
