You're probably getting negged because you appear to be disparaging the accomplishment. But yeah, they did copy over an existing dna structure, they didn't create one from scratch. However, the scientists did (according to the arstechnica article, posted above) have to remove a section of the DNA (something to do with the bacterium cutting DNA originating in yeast into small pieces... sigh, wish I understood this sor…

To be disappointed that they used existing DNA to do this is uninformed. We are so far away from synthesizing a completely novel form of life from scratch. This step is needed before we ever get close to designing our own cell — it's the leap from using hand tools to CNC.

I agree that disappointment in this accomplishment is crazy, it's an amazing feat

That said, people can sometimes go batty and start thinking something was achieved when it wasn't. I think it's reasonable to clarify that this isn't a full realization of "artificial life" just yet (though it clearly is a partial realization, as the scientists did alter the genome (also, apparantly they removed potentially disease-inducing strands of DNA, according to the NYTimes). The poster who got negged expressed this distinction in a fairly dismissive fashion that appeared to disparage the achievement. But you should be able to point out (diplomatically, one would hope)that a monumental achievement isn't an even more monumental achievement without being accused of minimizing the achievement itself!

Modern technology has already far surpassed the capabilities of natural organisms in a number of areas, all within a geologically minute timespan. They key words here are: "in a number of areas" In a number of areas indeed. Can a plane fly without oil drillers, oil refiners, fuel trucks, and jet fuel? Or in a more generalized form: For some X, thing Y is better at X. Having said that, I in no way belong to those peop…

I think quoting oil drillers is not really opportune at the moment if you want to give an example of how the damage from technology is going to be 'limited'.

See there's thing thing called an apple and this other thing called an orange.

And there's this discussion about artificial and natural micro organisms competing in the same niche. Like using light energy to capture CO2 for example.

And then there's oil drillers.

I agree. They wrote a new OS and uploaded it into existing hardware. Still a great feat, but not quite 100% "artificial life" yet.

More than that: an OS is millions of lines of code. The hardware is a hundred thousand. But cells! They have orders of magnitude more wiring than all the bits of DNA put into them. I liken it to a vast machine that can create either 1) a man or 2) a mouse. The dna programs the switch: man or mouse. Pretty trivial in comparison.

I agree. The cell is a much bigger challenge.

Your dog is genetically engineered. Your tomato. Your children. And I don't mean in the lab, but the usual way, by using your intelligence to choose suitable stock and then breeding until you get what you want. The shortcut in the lab is just faster and cheaper, not different in any basic or ethical way.

But that old-time genetic engineering still plays by the rules of nature, so to speak. Grafting branches between trees is pushing it a little. Splicing genes, not to mention synthesizing them from scratch, I think is pretty clearly of a different nature.

Golden delicious apples were a sport. Any really new feature in evolution is. The advantage of doing it in the lab is, its lots safer. You know what you're getting - just what you wanted. Not all the other random accidental changes you couldn't measure. Grandma's better tomato could actually make you sick - she had no idea what she was doing and no control over the process.

This is a huge deal, and I'm not surprised to see that Craig Venter had something to do with it. Kudos!

This is a nice step for technology and a really huge deal for human culture and religion. A certain Someone said once "Let the earth put forth vegetation, plants yielding seed, and fruit trees bearing fruit in which is their seed, each according to its kind, upon the earth." That certain Someone later said: "Behold, man has become like one of us..."

Walt Disney may have had a number of character flaws, but I always found the "if you can dream it, you can do it" quote very inspiring.

That comment can safely be ignored. It makes lots of vague accusations about Venter, and one concrete accusation - that Venter is responsible for patents on genes involved in breast cancer. That accusation is wrong: it's a reference to the BRCA patent by Myriad genetics, which has nothing to do with Venter.

Gripe: "artificial life" already has a somewhat lengthy history of usage, referring to emulating biological activity or traits in software or hardware. It's often shortened to just alife or a-life.

It's related to genetic algorithms, genetic programming, and the like.

It would be nice if the using-real-chemicals-and-alive-stuff hacking were called "synthetic life", or something to distinguish it from existing terminology.
