MIT Making Computer Parts from DNA 243

Posted by CowboyNeal from the growing-more-storage dept.
Rei writes "Following in the footsteps of Lynn Conway's pioneering work on VLSI that allowed ordinary students to create their own processors, a group of MIT professors have almost completed doing the same thing using DNA, known as synthetic biology. While not all of the components of a basic computer are working yet, there is hope that some day ordinary students may be able to design living computers, producing everything from novel drugs to seeds that sprout into treehouses."

        There are efforts to construct living creatures (all prokaryotic) de novo from nothing but inert chemicals and information from sequence databases. If these efforts are successful in creating a viable organism from nonliving sources, it should rightly shake our thinking in a number of fundamental ways.
        • First of all, if we succeed in creating life from non-life (and only non-life), we demonstrate that a process of abiogenesis is physically (i.e. kinematically and thermodynamically) possible. Abiogenesis has never been directly observed, only inferred from our existence.
        • If we can demonstrate abiogenesis, we also demonstrate a weaker possibility- if it's possible to create life from chemicals, it's possible to create life from matter that is no longer alive (i.e. dead).
        • We also demonstrate that abiogenesis may have happened before. After all, if we can make a bacterium from scratch, it isn't as farfetched to suggest that bacteria might have arisen from natural processes. Our technology is constrained by nature.
        • There is also a large class of interesting biological questions one might finally answer. For example, your DNA is right-handed and your proteins are levorotary. This is common to all life on earth. Nobody knows if a biochemistry based on left-handed DNA and dextrorotary proteins is viable or not. Some people say things twist the way they do because of chance in the way they evolved; others say things have to be this way because of the weak nuclear force or something. If we can create a "normal" bacterium from dead chemicals off the shelf, we can create a mirror image version, and directly observe how well our mirror-image bacteria digest sugars of either chirality.

          I guess that the modivation of most people over there at MIT is that they want to patent something and then live off of it for the rest of their lives.

          Being able to re-create life from dead things does not mean making them alive again... it just means you create a new life from the remains (inert) of another life form. Let's not get into "Pet Cemetary" like arguments here =)

        • The reductionistic approach of science has been pretty powerful in explaining many of the mechanisms of life and mind and finding remdies for their defects (disease). The construction of operations life from shelf chemicals would seal this argument.

      I think this story is more about creating life for a purpose that we do not find natually. Other than that, it is already here.

    So - humans playing God, synthesizing life from its basic components. Hubris, or something better?

    Without stating a position either way on the existence (or nonexistence) of God, what better way to glorify a Creator than by showing Him we've learned some of His tricks?

    (Allow me one assumption here: the assumption that if God exists, He's not a copyright lawyer, and will be flattered by our success, rather than whomping us with a Deistic Millenium Copyright Act violation notice in the form of a 20-mile-wide asteroid.)

    God: Cool trick. Now try it from first principles.
    Man: What do you mean?
    God: Well, next time, make your own dirt.

    And before you point out - correctly - that with a sufficiently large energy input we could indeed synthesize all the components that make up "dirt" out of hydrogen, you haven't solved the problem. Ultimately, it comes down to this:

    God: Look, I appreciate the flattery, and I encourage you to keep at it. But read the job description -- you qualify for My job when you derive a universe capable of evolving intelligent life based on the setting of a small number of physical constants, and you can have My job when your resume' includes experimental proof in the form of a portfolio that includes your worshippers.

    Their approach is pretty cool, where the activity of each gene corresponds to one bit (actually one analog "voltage", but I digress) that can be independently controlled. Unfortunately each cell in their "computer" is expected to behave similarly, so the approach won't scale. The problem is that each gene is gonna be at least 1000 base pairs, roughly. Compare that to a typical bacterial genome (~5,000,000 base pairs) or the human genome (~3,000,000,000 base pairs), keeping in mind that large portions of those genomes are there to, well, keep the organism alive. Right now they're not even talking about taking over whole entire genomes here, just plasmids and viruses. That'll get you in the ballpark of 100,000 base pairs, or 100 bits, at most. Oh yeah, for each transition in a circuit here you'll have to make a new batch of proteins. That'll take minutes to hours. Not exactly stellar clock speeds. Which of course begs the question of how nature gets anything done at all. It's still pretty mysterious actually, but part of it comes down to the fact that your cells use feedback in a much more nuanced way than just "on" and "off". There's also lots of parts re-use, but probably the most important thing of all is communication and coordination *between* your cells. Like the fact that each neuron in your head does something different, and all of them put together make up something interesting and useful (hopefully). Rudimentary cell-cell communication circuits are already being constructed, and I'd like to see these scientists incorporate some of that into their work.
