A Step Closer to Creating Artificial Life
slick_shoes writes to mention that Italian researcher Giovanni Murtas has taken another step towards creating life in a test tube. "To the untrained eye, the tiny, misshapen, fatty blobs on Giovanni Murtas's microscope slide would not look very impressive. But when the Italian scientist saw their telltale green fluorescent glint he knew he had achieved something remarkable — and taken a vital step towards building a living organism from scratch. The green glow was proof that his fragile creations were capable of making their own proteins, a crucial ability of all living things and vital for carrying out all other aspects of life."

If this technique (as mentioned in the article) can be used to artificially create fuel it can eliminate oilspills, because fuel can be produced where it is needed. Saves lots of coastal birds.
If this can be used to create artificial meat (now I'm extrapolating) there's no more need to have hurdes of hamburgers grazing away at acres of former rainforest. Saves many of those endangered but unknown species you're talking about. Maybe it can even be used to grow artifical hardwood.
Sounds to me this is exactly the sort of research that eliminates the impact of human consumption on the environment by making it more efficient.
Soon it will eat and outgrow everything!

The concept of matter ending up as human beings, and then being aware of its own existence, is mind blowing! Is there a scientific definition for life? I don't mean the using energy and waste - has dna - reproduces - want to will to survive stuff. I hope you understand what I am trying to ask. Like a clump of matter one day, then aware of its own existence the next day, what a transition!!
I've read that some say it just might be that it's all just a bunch of chemical/electrical interactions, but to get to the point where matter contemplates its own existence is just on a different level. So it's big bang heat explosion stars planets...then human beings (albeit much much later). Is that something you can say is a property of matter? That at some point it will know of its own existence?
What's/where's the threshold between a blob of carbon+goo, and me? Or at least, are there any theories? Or is all of this stuff discussed only in the philosphical realm?
For those who want more meat, these look like places to start:

Hey! It's called natural selection, and it's been going on for millions of years. Who cares if a species dies out? And don't give me that bull about finding "natural cures" in some substance produced by some obscure plant in the Amazon; that happens infrequently enough that your time is better spent on scientific research than random wilderness hunts. Bottom line is, life moves on. Or at least most of it does.

This new Bioshock game is pretty nice and all, but really does nothing to help those kids living with AIDS in South Africa. What the fuck.
welcome our green blob overlords
actually you will probably see recently extinct species coming back in the next 50-100 years, mostly in zoos and such but they will come back because of gene-banks, cloning, artificial life and all.
I doubt we will see a jurassic park anytime soon though. but im sure eventually they will dig up dna for t-rex aswell.
It all seems fine and well, what with creating life artificially but, speaking for all the red blooded American, European, African, and Asian males in the world there is just no substitute for doing it the old fashioned way.
At least that's what I hear.

That is a very close minded comment. By the same token I guess everybody working on computer science is wasting their time as they should be studying cancer research and trying to find a cure (and just running folding@home doesn't count).
The fact is, different people are good at different fields. Just because someone is a biologist or scientist in general does not mean that they studying all fields of biology. It is a highly specialized field with many different niches. Sure, the niches that some fill may not *seem* to be cutting edge high profile making the headlines ground breaking research. However, every bit of info that is documented may be useful someday.
And by the way... I think being able to build something from scratch is a pretty damn good way of learning out something works and how to help it.
Just wait a few billion years, and they evolve to the point where they acquire an additional capability :
- starting pointless holy wars about the subject whether they evolved spontaneously, where created by intelligent design or where by a giant flying spaghetti monster.

I'm pretty sure the 4 1/2 week old smart chicken in my friends fridge last night was evolving into some sort of lifeform. one with a bad bo problem.
If they are made of exactly the same thing, then what is the difference, or is it kinda like calling Organic chemistry to everything carbon bond related?
Hrm... I knew they sort-of successfully cloned humans, but this is really the next step... I don't know what to think of it.. I mean, there is quite a lot on this planet already that we don't know a lot about. why create a new lifeform? ...probably because "it's possible"...

What does from scratch mean? Are they using existing cellular and biological materials (i.e. ones that are already partially "assembled")?
Hey! It's called natural selection, and it's been going on for millions of years.
Natural selection, damn right, more like mass extinction. Calling it natural selection would be like saying that the dinosaurs died due to natural selection. Plus, how is that natural selection when elephants are getting killed for their ivory? If that's natural selection than I guess genocides are natural selection too and so maybe jews and darfurians are unfit to live on Earth..
Life moves on indeed!
You just got troll'd!
Well, it is Natural Selection, which only goes to show how insufficient an excuse natural selection is. Humans are a natural selection pressure force (unless you believe that we were placed here by divine or other supernatural powers...pleh) just like any other species. Humans are unlike most in that we can, if we choose, attempt to gain awareness of what our effects are, and modulate some of them with a bit of effort. That we can change things to accord to some moral conception of proper living within an ecology or not is a different issue, quite beyond the notion that it is, at base natural selection at work.
The problem here is you are identifying a normative impulse in the phrase Natural Selection (natural=good, artifical=bad...roughly) and then complaining that the normative meanings being assigned are insufficient to describe the actual moral consequences of the situation. I'd say it would be better to read "natural selection" as a descriptive term only, and take moral considerations where they belong, which is in identifying when and how human actions can be good or bad.
All the techniques ever used to make men moral have been themselves thoroughly immoral... (Nietzsche)

You include 'has DNA' in the list of criteria for life specifically, I assume, to exclude alien lifeforms. Is this bigotry innate (and evolved!), or did you have an unfortunate childhood experience with some shales and a magnetic vortex based master intelligence?
As to your question, if you put a learning and abstraction engine into an environment with multiple (near-)copies of itself and ask it to plan for the future, it's pretty clear that the useful (i.e. adaptive) option among the possible outcomes is approximate self-modeling. For many technical reasons it's tricky to get right, but nature had lots of time, and provided plenty of impetus, to work on it.
If you don't think that's a strong enough answer, then consider this: how can you prove to me that you are self-aware? How can you prove to yourself that you are? Reflexive social planning ("I know how to do this, but if I try I will be too scared to go through with it, so I had better take a friend....") is the best evidence you can give me.
Man (in his current form) will die soon enough, and then new life forms will come along. It's not like the SUV-driving, McDonalds & Starbucks eating, petrol-dependant society can continue forever. Our days are numbered.
The Death of the dinosarus was due to natural selection in that there environement changed and they couldn't hack it and died. If you would calm down and think about it some furry little things did survive and so by natural selection we got lots more mammals and way less dinosaurs. As for Jews and Darfurians, last time I checked they were all homo sapians. Natural selection has been kind to homo sapians, just because other homo sapians haven't been kind to those homo sapians doesn't make thier situation at all related to natural selection. As for the seals and birds that die in an oil spill, guess what natural selection. Humans are part of nature too folks and dealing with the shit that the dominent species leaves lying around is key to survival. Pigeons for instance have learned to live with us quite well as have rats. Isn't natural selection fun.
"In an interview with Newsweek magazine earlier this year, Dr Venter claimed that a fuel-producing microbe could become the first billion- or trillion-dollar organism. The institute has already patented a set of genes for creating such a stripped-down creature." A fantastic money making idea. However, do we really need an unlimited supply or carbon positive fossil fuels? I can just see the motorways jammed with Stretch Humvees of all shapes and sizes, gracefully spewing that grayish black smoke into our already pissed off atmosphere. With cheaper fuel prices, why walk? why cycle? Everybody will drive. We'll need more and more roads to cope, how will we manage? Bulldose the already thinning vegetation on this planet to build that new bypass we all REALLY need. Shit, it'll be fine, they'll probably come up with an organism that can take carbon dioxide and produce oxygen! Now what a feat that would be, modern science today hey...
You feel sleepy. Close your eyes. The opinions stated above are yours. You cannot imagine why you ever felt otherwise.
I don't mean to come off as some sort of Chicken Little or something, but I worry sometimes about scientists getting a little careless. Certainly this research is awesome and I'm all for it, but I hope that there is someone in there really giving some thought to keeping these new lifeforms from getting out and killing everything on the Earth. Scientists often have the attitude that what they are working on is awesome and good and poses no danger to anyone. "These life forms can't possibly hurt us, so why contain them?!" So they take them home on their shirts and the things evolve and bad things happen. Again, I don't want to rain on the awesome parade or anything, but I hope that someone in there is giving this some thought and maybe, once they get somewhere, they'll start taking precautions to contain this new life.
I for one am glad people don't spend more time trying to preserve nature. "The balance of nature" is a false term, and such a situation where everything lives in harmony simply doesn't exist. Nature is wild, crazy, unpredictable, and I honestly don't think humanity has the capability to "preserve" it. Don't believe me? Just take a look at the disaster that is Yellowstone National Park, if you don't believe me.
Real men eat soylent green.
I welcome our new overlord, Giovanni Murtas and his army of goo.
I doubt it. Mankind will find a way to keep our prosperous energy-dependant societies going strong.
you used the word "efficient", but did you mean "sustainable"? I'd totally agree with your line of thinking. if us humans, at least in the developed parts of the world, can ever shake the use-once-and-toss mentality we'd be a lot better off for it.
So you're saying that us killing elephants and such one by one until there's hardly any left is natural selection, but that killing Jews doesn't make it natural selection because, according to you, Jews are humans? (heh, I love the ambiguity of this question)
You just got troll'd!
You're just not playing it right. If you kill 50 Big Daddies using just the wrench, all the Little Sisters turn into kids living with AIDS in South Africa. Of course, the "ADAM" is replaced by the "AIDS." For each one you rescue in-game, a kid is saved in real life! I've saved the lives of over 100 kids living with AIDS in South Africa by playing Bioshock. What have YOU done?
Reading the article, it doesn't exactly sound like anyone is truly building life from scratch. Building life from scratch would be assembling from base elements the building blocks of the cell, assmbling from base elements the walls and structure of the cell, putting it all together, and then starting up all the "machinery" and watching the cell come to life. As far as I know, no one has been able to do that, and it doesn't look like these teams are doing that either.
The top down team clearly isn't close to doing things this way, because they are taking already living cells of a simple organism that is already alive and tweaking the DNA, trying to find the minimum set of genes necessary for function.
In contrast, the bottom up team takes enzymes from already alive sells, puts them into a stripped down fatty bag cell and watches them synthesize proteins. That's hardly creating life from scratch. That's taking bits and peices from things already alive and trying to create a new organism out of them. While this technique may indeed succeed in creating a new, minimal organism, there is a large difference between taking nothing but inert, base elements from the periodic table and creating something alive and simply taking peices from other lifeforms (by definition already alive) and assembling a different organism. And there is also a large difference between having enzymes make proteins in a test tube (something that has been done before) and creating something that is alive.
We've never seen anyone truly create life from scratch, and I don't think we are particularly close to that, if it would ever even happen. I think most of this "I've created new life in a test tube!" stuff is propoganda from scientists to gain more funding. Saying "I've created life in a test tube!" tends to sound better and garner more funds than saying "I've tweaked existing life in a test tube!", which is what has actually occurred here.
Beware of bugs in the above code; I have only proved it correct, not tried it.
I know about the desaster in Yellowstone National Park and I know of other failed attempts to "preserve nature". But I still think that there should be more interest in trying not to let so many species die out once and for all because we destroy ecosystems by the thousands of sqare kilometres. Not because those species are cute and furry, but because we will need them and the ecosystem they make up, deseperately, one day.
I find it rather disturbing that one of those groups is creating a new life form out of the bacteria that causes urinary tract infections. Wouldn't it be a kick in the pants if this new life form caused your ..., well you get the idea.
Extinction is great!
Gotta make some room for new species! Or would you like to keep the dinosaurs around as well as giant ferns and various animals that cannot even survive in today's atmosphere? Fact is, pretty much anything that have ever lived on earth is extinct. That's life.
Now, you need to focus on the real problem: Too damn many humans. Sure, redundancy is good, but this is fucking crazy.

FINALLY! nerds will have (cute) girlfriends!
Cue bio-spills, accidentally dumping tonnages of engineered life into the ocean. Chances are it would be quickly eaten up by local life, as it was engineered to do something very specific and is likely nowhere near as "fit" as evolved life to live outside of otherwise sterile vats of goo. Still, who knows what a mutant strain of human-created life could do.
Well I did use some words carelessly, but efficient is more or less what I meant: Less (negative) effect per person. You're right in saying that sustainable is still a way off from that and I did skip over that. Mostly I'm afraid that more efficient per person means more room for persons, ending up with the same total result before tragedies like war, disease and starvation regulate the population again. The OP is right in that sense, because no engineering solution, except maybe faster than light travel, can avoid that pitfall. If any social, political or other solution can go against nature like that is something I am skeptical about. In the meantime technical solutions keep us ahead of the curve. They buy us time and save some of the more vulnerable species until we figure it out.
If you attempt to build life from scratch, you must first create the universe.
Yes thats correct. Maybe we are using different definitions for that natural selection is. I am saying that natural selection is the process by which forms of life having traits that better enable them to adapt to specific environmental pressures, as predators, changes in climate, or competition for food or mates, will tend to survive and reproduce in greater numbers than others of their kind, thus ensuring the perpetuation of those favorable traits in succeeding generations. So the elephants are not doing well against thier predators aka humans. How is that not natural selection. The persecution of the Jews could be considered a form of natural selection but it certainly not analogus to the elephant example. Elephants are a species hunted to the edge of extinction where as Jews are humans and humans are doing just fine. Can you explain to me where the ambiguity is.
I wish more people would invest their intelligence into how to protect the life forms (and that includes everything from slimy single-cell organisms to snow tigers) on this globe that are already there. Nobody will be able to bring them back, ever, after they are gone.
Are you... insane? Being able to create arbitrary life in the laboratory is EXACTLY what will be necessary to "resurrect" the species we are currently wiping from existence. The polar bear, among many other species, is probably going to be extinct within 50 years. At this point there's probably nothing we can do to stop that. But if we can learn to recreate its living form from scratch, we might have a chance to save these species in the future when their habitats have been restored.
If GreenPeace actually SOLVED ANYTHING they would have to close their doors. People fear being out of work. People fear the freedom that would come from solving the energy crisis and every other crisis. We have even come to fear doing the "right thing" by the rest of creation on this planet. Running on money reduces us to a lower form of life that makes stupid decisions. The automobile engine needs a total re-design, makeover. It's designed all wrong. As is now, the highly-efficient combustion engines (all kinds, + factories) are competing with human lungs, which are extremely inefficient. We actually exhale most of the oxygen we inhale. That's one big reason our bodies aren't metabolizing fat. Low oxygen = low metabolic rate. Google search for "self hyperbarics".
. That page also tells how to stop malignant cancers with nutrition-induced chemical burns to the insides of cancer cells while not harming normal cells.
However, once we start doing things right, increment by increment, we will find how glorious it makes us feel. Once we latch onto that things may begin to change.

green blobs create you!
Maybe we are using different definitions for that natural selection is. I am saying that natural selection is the process by which forms of life blah blah blah...
Well my definition for natural selection is "Natural selection is the process by which favorable traits that are heritable become more common in successive generations of a population of reproducing organisms, and unfavorable traits that are heritable become less common." (from Wikipedia). Therefore, the extinction of an entire species is not natural selection, in other words none of what we talked about here has anything to do with natural selection.
Can you explain to me where the ambiguity is.
"according to you, Jews are humans?"
You just got troll'd!
You may want to keep reading beyond what natural selection is and on to what the consequences of natural selection are. No one is saying that the extintion of elephants and the sucess of rats is a good thing, its just a fact.
As for your question
"according to you, Jews are humans?"
YES Jews are humans! What do you think they are Homo Jewish? I really don't know how we can continue this back and forth unless you except the fact that humans of Jewish decent are in fact still humans.
