Synthetic DNA About To Yield New Life Forms

Posted by kdawson on Tue Dec 18, 2007 01:19 AM
from the what-could-possibly-go-wrong dept.
mlimber sends along a Washington Post story about the immanence of completely artificial life: "The cobbling together of life from synthetic DNA, scientists and philosophers agree, will be a watershed event, blurring the line between biological and artificial — and forcing a rethinking of what it means for a thing to be alive... Some experts are worried that a few maverick companies are already gaining monopoly control over the core 'operating system' for artificial life and are poised to become the Microsofts of synthetic biology. That could stifle competition, they say, and place enormous power in a few people's hands."

        That depends on your definition of "maxima".

        Even with survival constraints as the basis for a successful design, it can't be denied that an intelligent designer could have come up with much better designs than the ones you see. Attributing evolutionary designs to an intelligent being is practically an insult when you look at some of the shoddy work evolution has come up with. Our testicles, for example, hang from our undersides dangerously exposed, just because some protein denatures at core body temperatures. Apparently something needs to be redesigned that can't be made to work better with slow incremental improvements. Evolution's fix: make them hurt like hell when struck so you learn not to mess with them. A Microsoft-style hack. If we threw a bunch of supercomputers at the problem we might come up with a completely different protein design that would allow reproduction with undescended testicles.

        Disregarding survival constraints as a parameter, a world of possibilities opens up. There is nothing in physics or chemistry that prevents the existence of almost any organism you can imagine, so long as fundamental physical constraints are adhered to such as conservation of energy, rising entropy, etc. I'd like an animal with wheels that I can drive to work, with chlorophyll in its skin so I don't have to feed it. Maybe it can sun itself on the roof while I'm at meetings, and ooze a delicious health drink from a special orifice so I can catch dinner on the way home. (Don't spit up your milk laughing, it's quite possible.) A creature like that would go extinct pretty quickly but it would sure be convenient to have one, and no law of nature prevents such a thing from existing.

          Please speak for yourself, I like my testicles where they are thankyouverymuch. You might at well argue that we should have our genitals protectively hidden deep back in our throats and that we inseminate the females by spurting out the damn seed while we french kiss. or something. Wait, that was awful, sorry.

          While there is probably a lot that can be improved in the engineering of human bodies, I find it slightly disheartening that after thousands of years of learning we are still unable to create a single complex living cell without help from nature. When we do, it will be the greatest feat of engineering ever, and I will party like hell.
          • When we do, it will be the greatest feat of engineering ever, and I will party like hell.
            It'd be more of a triumph for analytical and organic chemistry, really. Analytical chemistry provides the high-resolution structure of the various components, and organic chemistry provides the reactions to synthesize them - all the engineers would be doing, is putting everything in the right order. It would require precision, certainly, but I'd assign more credit to the chemists.

          You seem to know little about this subject.

          Testicles are among the least of our concerns... what SHOULD concern you, especially in a "SURVIVAL" related subject, is that man seems to have been meant to stay on Earth (until man gets over this particular problem.)

          See, man is one of TWO mammalian species that requires an external source of vitamin C... otherwise we get scurvy... and eventually kick the bucket. Interesting that Earth's apex predator is range limited by something so simple as carrying a satchel of oranges or lemons on the ship... (okay, not all specimens of homo sapiens qualify for more than "monkey" classification, granted, and some are not capable of even surviving in society, nevermind without said crutch.)

          However, a voyage to the stars, without a good supply of replenishable vitamin C would become a trip delimited by a few days/weeks past the day when the vitamin C runs out.

          Pretty sad, when you think about it, every schmuck is looking at all these "big" problems, instead of looking at the fundamentals. Testicles and their placement on the body is nowhere nearly as bad as the fact that every single instance of homo sapiens in space would be cut short by the vitamin C supply. Ironic really, perhaps "intelligent design" might warrant a second look, unless of course, evolution and any supernatural forces others might attribute evolution to "realized" that man was a plague, and should be limited to Earth until it managed to kill itself off, whether by grey goo, killer designer virus, or just plain good ole' nuclear warfare.

          If that isn't a vote for intelligent design or intelligent forces of evolution, I don't know what is :)
          • Your post is a little moot. EVERY organism on earth is meant to stay on earth. Every voyage to the stars is limited by water, food and oxygen. Vitamin C is least of your worries as you can just take a few kilograms of pure Vit C. It's so cheap it is even used as a preservative in many many foods. But you can't live JUST on it.

          Which explains the survivability of so much hackish, clumsy, but real-working software. See, software, or life organisms persist to the degree that they solve real-world problems. How "elegant" the solution is is rather secondary. Often, real-world problems are ugly, pseudo-random nasty problems that don't have a clear, simple, ivory tower style solution. I maintain a large, complex, beautiful software codebase that has the ugliest, most horrible hack of a pile of regex and scripting as its very center. The nasty hacks have been amazingly stable for years now, and work well, even if they are a serious pain to edit during the (very rare) need to edit.

          It's carefully sandboxed - the ugly part sits in a single file that is itself wrapped inside a handler function, so the "pretty" part of the codebase is *never* contaminated by the ugly, "written in a day or two" hack that got the whole shebang started.

          Sometimes, no matter how much you kick and scream, you have several screens of ugly case statements littered with random function calls, and you end up with a great big ball of mud [laputan.org].

          Guess what!?!?! Look in the mirror - YOU ARE A GREAT BIG BALL OF MUD. Your body is a complex set of unclear, un-abstracted dependencies without clear boundaries. For example, we've long thought of the pancreas as a key component of blood sugar control. But recent research shows that the bones (yes, bones!) of the body also contribute to positive blood-sugar control [nytimes.com]. As a borderline type-II diabetic, I pay attention to things like this...

          Millions of years of evolution (or a few years of hard work by a half-drunk God) have resulted in your body, which is a festering pile of weird dependencies. For example, if you don't get exposed to enough dirt as a baby, you end up with asthma [bbc.co.uk].

          If Microsoft's software is truly evolutionary in nature, that would explain its dominance in today's marketplace - it's well adapted to survive in the software environment we've seen so far, and like the dinosaurs, it will only be beaten back when the basic environment changes. (which it is)

          Get used to the world of "dirty" evolutionary solutions - it's the basic building block of life itself!

    who says artificial life needs to be based on DNA? The earliest forms of life probably used RNA instead or one of its cousins like TNA, GNA, PNA or LNA. DNA is only special in the fact that it is missing a key hydroxyl group in the 2 position. this makes DNA more stable because there's no nucleophillic group there toi assist in self-cleavage of the phosphodiester bond. GNA has a backbone of glycerol rather than ribose [RNA] or deoxyribose [DNA]. PNA uses a reperating serine polypeptide backbone and because the whole thing has no charge like DNA does it has a much higher melting temperature [can withstand more heat] which may make it superior to DNA or RNA in some applications in biology. TNA on the other hand, has a synthetic polymerase enzyme that has to my knowledge, been able to create strands 1000 bases long. then there's alternative nucleotide bases, there are similar molecules to the naturally occuring 5 that also can encode for proteins and act in genetic systems. there's a lot that can be done with this, it's just a pity that it will probably be encumbered in patents if and when any of it is realized.

It was only yesterday, on the historical timescale, that we discovered DNA and now we are beginning to get some vague ideas about how some of the things actually work. We can even theorize about correcting errors in people's genetic code, but creating a living cell from scratch?

    It should be pointed out that the technology described is largely fictitious. The best labs haven't even managed to create a single artificial cell, and those technologies ALL use cobbled-together bits stolen from other lifeforms - nothing truly from scratch. There are a few good examples of proteins being engineered to specific functions (mostly DNA binding specificity), but we're ages away from being able to say, "Okay, I want to synthesize a protein that does this random function; here's how I would do it." And as for more complex lifeforms? Forget it. We don't even understand the development process of any multicellular organism in any detail, never mind being able to manufacture our own.
