Those who believe in magic as the best explanation for the beginnings of life had better start to develop a strategy for moving their goal posts again. The god-gap of creating life is about to be filled by science...Artificial Life Likely in 3 to 10 Years
"It's going to be a big deal and everybody's going to know about it," said Mark Bedau, chief operating officer of ProtoLife of Venice, Italy, one of those in the race. "We're talking about a technology that could change our world in pretty fundamental ways — in fact, in ways that are impossible to predict."
That first cell of synthetic life — made from the basic chemicals in DNA — may not seem like much to non-scientists. For one thing, you'll have to look in a microscope to see it.
"Creating protocells has the potential to shed new light on our place in the universe," Bedau said. "This will remove one of the few fundamental mysteries about creation in the universe and our role." |

I agree. I even warned Bill about this. But he ignored the advice. When it happens, he'l be caught flat-footed like most of the YECs, because they don't follow science.

I highly doubt that he'll be flat-footed enough to not try dancing around the issue with various fibs, obfuscations, and biblical pronouncements. He probably won't even skip a beat.

As Ricky said, more or less, the fundies will just offer this up as proof of intelligent design.

Szostak is also optimistic about the next step — getting nucleotides, the building blocks of DNA, to form a working genetic system.
His idea is that once the container is made, if scientists add nucleotides in the right proportions, then Darwinian evolution could simply take over.
"We aren't smart enough to design things, we just let evolution do the hard work and then we figure out what happened," Szostak said. |
Still, the creationists will lie and dissemble. It's all they've ever done.

This is pretty damned remarkable, if not unforeseen, and really, who cares what a pack of religious Luddites think? To them, if it ain't in the Bible, then it just, plain ain't, and no quantity of microscopic proto-wigglers will change their minds. They will, as stated, simply put the goalposts clear back into the cheap seats by insisting that the proto-wigglers can't be alive unless they wiggle.

Don't you find it slightly unnerving that we can create a new life-form?

| Good thought, but no. This new "life form" is/will-be little more than the most primitive of cells, and possibly even less. The wonderful thing about it is that ancient evolution might be observed in the lab. Whether or not this duplicates any sort of orginal abiogenesis remains open to question.
It would be neat if this evolution could be guided into a SF addicts wet dream, but I don't see this happening, nor currently even possible, and certainly not in any manner of the short term. For the forseeable future, I think, it will remain a lab exercise, perhaps one day becoming an assignment for aspiring evolutionary bioligists.

It's really fascinating but also scary. The part that scares me is this - "A metabolism that extracts raw materials from the environment as food and then changes it into energy."
Makes me think of this : http://www.livescience.com/technology/destroy_earth_mp-1.html
Its the von Neumann machines. Only they are biological this time. I pretty sure the scientist doing everything possible to ensure safety. And those cells aren't going to last too long, but.....you never know.
Their would be some humour in this. To quote the grade b film "Crack in the World" General: We'll at least we're not to blame..this time.

That's happening all aropund us even as we speak. For exapmle: "Epsilonproteobacteria" and Gammaproteobacteria, characterized by fluorescence in situ hybridization, colonize carbonate surfaces and generate sulfuric acid as a metabolic byproduct. The bacteria focus carbonate dissolution by locally depressing pH, compared to bulk cave waters near equilibrium or slightly supersaturated with calcite. These findings show that SAS occurs in subaqueous environments and potentially at much greater phreatic depths in carbonate aquifers, thereby offering new insights into the microbial roles in subsurface karstification. | This wasn't the article I was looking for.
What it boils down to is that these consume minerals and excrete sulfuric acid.
There are many others, such as the microbes living in hydrothermal vents, which feed upon hydrogen sulfide.
But in all probobility, at least initially, these cells won't be able to survive outside of the lab.

True, the article does mention the short life span. Maybe I read to much Sci-Fi.
The possibilities are numerous. You could forsee the beginning terraforming with this technology. |

Every last living thing does this. You do it, too. The difference between life and the von Neumann machines is that they - hypothetically speaking - are not also constrained by the environment, and so reproduce indefinitely. Bacteria, for example, eventually eat all the food around them, and poison their own living space with waste, which limits their ability to double their population every day or so. There are a whole lot of 'em, but if they were little cellular von Neumann machines there'd be nothing on Earth but bacteria.
In other words, I think your worry is misplaced.
No, what you really should worry about is the accidental creation of a super-pathogen that makes the Black Plague look like the sniffles. |

That's what I am thinking of... note to self. Don't post until you've had 3 mugs of JAVA.
On my drive in to work, NPR had a segement on ITER. Way cool.
P.S. This is first time I was able to embed a URL with a tag. I've been looking at the icons for the reply, insert url, picture et al. I didn't how you guys did it. Until I tore apart one of the posts. P.P.S. Please forgive my noob giddyness...but this was big for me. I may be opposed to some of your views...but MAN I LOVE THIS SITE!!!!!

But then, would they need a whole new synthetic life to do that? Why not just bioengineer the ones that already exist? |
