I think it's much less likely to kill us all than naturally occurring bacteria. "Real" life has evolved over millions of years to exploit every conceivable weakness in every conceivable environment. There are already tons of bacteria out there that would be perfectly happy to kill you today. Some junk created in a lab probably isn't going to have a chance in hell of actually competing if it's let out of the lab. Evolution is running trillions of experiments right now, looking for ways to get ahead.

One question is whether or not a DNA sequence alone enough to generate a living creature. One way of reading of the paper suggests this doesn't seem to be the case because of the use of old microplasma cells into which the DNA was inserted — that this is not about "creating" life" because, the new life requires an existing living recipient cell. If this is the case, what is the chance of producing something de novo? The paper might appear to be about a somewhat banal technological feat. The new techniques build on existing capabilities. What else is being added, what is qualitatively new?It sounds like a qualitative step to me but I'm not a biologist.
While it is correct to say that the individual cell was not created, a new line of cells (dare one say species?) was generated. This is new life that is self-propagating, i.e. "the cells with only the synthetic genome are self replicating and capable of logarithmic growth."

Bullshit. Evolution isn't an active agent. It's passive. The things that survive survive because they don't die. That's it. 'Evolution' isn't looking for ways to get ahead. Things are just looking to not die. There's a big difference. Usually, the bare minimum will suffice and is often preferable.
Furthermore, evolution is incremental. Life that could be synthesized in a lab would not, and can be very unpredictable.

Venter is looking to engineer organisims for maximizing their biofuels. I'm guessing by a totally synthetic approach (as opposed to the status quo splicing methods) is that he can get a better control over where the artifical genes are inserted, and maybe be able to genetically engineer a wider range of species. I am definitely not any kind of biologist, though. Are there any qualified MeFis out there who care to comment?

So let's see if I understand this: They sequenced the genome, put it into a computer. Then they used the data to produce a synthetic copy of the genome, and plopped it into a hollowed out cell? And it worked? Pretty cool!
Seems to me the next step is to start switching some of that data around and plopping the output into hollowed out cells to see what happens. Step 3: Zombies?

This is another incremental advancement, not a paradigm shift. Scientists have been able to clone cells for years by swapping a cell's native DNA with DNA from a different biological source. They've also been able to chemically synthesize DNA from scratch, though until recently, they've been limited to rather short stretches. The advancement here is that Venter et al came up with some clever techniques for stitching together those short stretches of synthesized DNA into longer stretches, and then stitching those into even longer stretches, etc, until eventually he had a full-length genome. Then he shot the completed genome into a cell with its native DNA removed, thereby transforming one species of bacteria into another.
In theory, one could use any genome with this technique, though the transcriptional machinery of the host cell might limit compatibility to related domains or phyla. We're still lightyears, however, from creating de novo functional genomes, rather than simply copying existing genomes. The next step will be taking existing genomes and modifying them slightly in order to try to alter their phenotypes in desirable ways, i.e. to produce drugs or biofuels.

Think of it as a bacterial chromosome frankenstein. Pieces were selected and spliced together to see if they would live (i.e. multiply and divide). This is an important step as it allows one to use a constructive approach vs. destructive (eg remove a gene and see what happens).
The hype seems to make far more of this important but small step ahead.

I can never tell if people here are genuinely afraid of this sort of thing, or just being fashionably snarky. Just in case: you should be aware that surviving in a human host is no easy trick, since the immune system wants to kill you. Furthermore, releasing toxic compounds that can kill the human host is also difficult. These things don't happen "accidentally", any more than your iPhone would accidentally obtain sentience and proceed to murder you with a spontaneously generated lightning gun. Of course, someone could (far down the line) maybe make biological weapons with this technique, but deadly biological weapons already exist, and I don't see how this technology would make them easier to obtain.
The sorts of organisms produced by this kind of research are deliberately stripped down. There's two basic techniques being pursued: a) remove genes from existing organisms, b) build stripped down organisms from scratch. The payoffs from both approaches are also two-fold: 1) improved understanding of how microorganisms work, 2) microorganisms with dramatically lower overhead. Because they lack the complicated genomes and associated defense mechanisms that wild organisms have, these cells are better able to produce "product" for industry, whatever that might be. They become little factories. However, unless deliberately turned into weapons, they are to wild microbes what wiener dogs are to wolves.
Oh, and since the article raises the question without really answering it. No, a genome by itself does not determine an organism. We inherit DNA from our parents, but also the cellular machinery to do something with it.

Actually, the next step here, which Ventner himself has been talking about for some time, is to make a new bacteria with a minimalist genome. The point is for create an organism that can serve as a simple self-replicating scaffold in which synthetic biologists can set their creations. By reducing the number of genes to a minimum, you can greatly reduce the probability of unanticipated side reactions or interactions.
This paper shows that Ventner and others have the tech for synthesizing whole genomes and swapping them into cells. Next comes the experiments for minimizing and simplifying the genome. The product of that will be the vehicle for a whole lot of cool new stuff, solar biofuels are the least of it.

I think it's fascinating that the media give Venter personal credit for this advancement. Venter is more Edison than Einstein, running a network of labs with hundreds of PhD biologists and probably several thousand support personnel. Some of the money comes from investors, some from nonprofits, and some from Venter's personal fortune, but the biggest chunk comes from you and me in the form of federal grants.
If a university had done this, the news stories would read "Researchers at Kalamazoo State did X," with the understanding that the project was the cooperative work of many smart people. That's if it even made the news, because university PR departments are nowhere near as coordinated as Venter's. But when a team of scientists at the Venter Institute finish a project, it's as if he were personally putting things into test tubes.
Then again, we all give Edison credit for inventing the light bulb.

Venter is a self aggrandizing douche-nozzle.
It's cool that he has the money to work on new techniques, but his (and the mainstream press's) exaggeration of the profoundity of said techniques disserves molecular biology and science in general.
(Current) Extreme length nucleotide synthesis is getting longer and longer all the time. I've been getting spam about being able to buy 1kb (1000 base pairs) oligos (and presumably, double-stranded DNA) - basically, many many many strands of DNA that's made chemically, where every base pair is decided by whomever makes the strands of DNA. The limitation is that the longer (and more strands) that you make, the more errors are introduced (or rather, more and more of the strands have errors in them - there's also a limitation on long long individual strands can be made without earlier parts of the strand being damaged).
Actinomycetes (a very common group of soil bacteria - of which most modern antibiotics are discovered from) have a genome between 5 and 8 megabases (million bases), mycobacterium have about 0.5 megabases. Humans have about 3 billion (3 gigabases? that doesn't quite sound right to me right now) base pairs.
If they moved mycobacterium nuclei from one cell to another, that's like moving something (mycobaceterium genome) on an old floppy disk to moving a bunch of somethings (common bacterial genomes) on a zip disk to moving something (human genome) on a DVD.
Funnily, if you get a sequence of DNA into something like a plasmid (think... "handles" for the bacterial machinery to get their sticky little hands on), the error rate (in tame, domesticated bacteria developed to do exactly this) is infinitisimal.

Why do you need minimal genomes for that? It seems like you'd just wind up with something less robust than, say, E. coli or S. cerevisiae. Things that metabolic engineers have been working on for the past 30 years to make biofuels, natural products, etc. This is well-tread ground, my friend.

Will you accept, "There are a trillion parallel experiments going on right now where the things that come out ahead win." Because if come out ahead = kill and eat you it doesn't mater whether or not you anthropomorphise this phenomenon or not because you will still be dead and eaten.
I got pretty good at synthetic chemistry by learning what it was the electrons wanted and giving it to them. You can say they don't want at all but they still come when I call and sleep on my side of the bed.

We are now in the business of engineering life.
For "we", read "the US military and her largest corporations", of course.
You have a kitchen, get your ass in gear.

It is my sincere belief that everything J Craig Venter does is part of a long-running audition for the part of a Bond villain.

Ebert reviewed the Human Centipede today.
Why couldn't that say "Ebert interviewed the Human Centipeded today" the both times I read it?

That's still not really our own original design at the most basic level, right? I think it's fine to call some of the robots that we can create life: they are animate and self-sustaining.

We've been creating life for a long time. It's as easy as fucking (and eventually pushing really hard).

Synthetic life patents 'damaging': A top UK scientist who helped sequence the human genome has said efforts to patent the first synthetic life form would give its creator a monopoly on a range of genetic engineering.
