Will synthetic life do more harm than good?

18:10 UK time, Thursday, 20 May 2010

Scientists have developed the first synthetic living bacteria. What is your reaction?

The new microbe, dubbed "Synthia" by opponents, contains a DNA sequence designed and built by scientists. Its creator Dr Craig Venter hopes eventually to design and build new bacteria that can perform useful functions - such as producing medicines and fuels or even absorbing greenhouse gases.

But critics say there are dangers posed by synthetic organisms. Dr Helen Wallace from Genewatch UK, an organisation that monitors developments in genetic technologies, said: "If you release new organisms into the environment, you can do more harm than good. We don't know how these organisms will behave in the environment."

What is your reaction to this new microbe? Are you excited, or concerned, by the potential of synthetic biology? What limits, if any, should we place on research into synthetic living organisms?

This debate is now closed. Thank you for your comments.

    I doubt that it will do much harm at all. It will develop into valuable advances for mankind and our planet as a whole.
    For those who have an imaginary friend and think we are playing god, yes we probably are, and we are getting very good at it. It's no longer just nature that can create new life. People can do it too, although we are just part of nature ourselves really, aren't we!

  • Comment number 2.

    An historic breakthrough, from a dark corner from Pandora's Box.

  • Comment number 3.

    You can't control evolution.
    It only takes one of these bacteria to mate with another and you have serious and posibly extinction problems.
    Not a good idea.

  • Comment number 4.

    This is an incredible development with such amazing potential - for both great good and great harm. I would like to see this technology very carefully controlled so that the benefits can be realised without unleashing some new terrible weapon on the world.

  • Comment number 5.

    Synthetic life is absolute rubbish because real life is all that matters. It's insolent to behave like a creator of the whole world and there won't be any advantages of this research. It should be abandoned.

  • Comment number 6.

    This is a great discovery, and the potential benefits are unlimited.

    And yes, the potential dangers are unlimited. But if you look at every single thing invented in the history of mankind, there is nothing you can't say that about.

    Planes make world travel a lot easier and quicker. But you can hijack them and use them as ballistic missiles to attack buildings.

    Knives are good for hunting and fishing and cutting food, but can also be used for killing people.

    The majority of prescription drugs can be used to poison people, and yet I would say the majority of people would say that they are generally good things that save lives.

    From simple things like matches to insanely complex things like nuclear power there is nothing that can't be used for ill as well as good, but that is not a reason to use them.

    And if you stop scientific research because you think what you might learn could be used for bad, then you might as well stop all scientific research completely, and the country can return to the dark ages when religious dogma ruled the country.

    Existing natural bacterial organisms are already 'harnessed' and used to break-down our own waste in sewage farms - and contribute to breakdown of waste in landfills?

    With all of the above working with nature/naturally available bacteria - free of charge - obviously there is no intent to 'patent' a GM bacteria to do the same work? This is not a new story, or even a new invention?

    If this was 'true' bio-tech - fair enough - but ... ?

    Naturally - where there's money - someone has to re-invent and charge for the the wheel we already have and own - for someone else, again?

  • Comment number 8.

    "In 1979, The Progressive published the blueprint for the H bomb, so perhaps enabling India, Pakistan and South Africa to develop this weapon. Venter’s Science paper is not such a complete blueprint. But it may be the first part of it. In the mid-twentieth century, many physicists knew that their work could be used both to do much good and to inflict great harm. For the life sciences, though, this dilemma has never been as acute as it is now. Though other types of bio-science can be misused, the risk of misuse has never been as serious as it is with synthetic biology. There’s been a tendency to assume that the life sciences are unreservedly a force for good, and that we needn’t worry about their misuse in the same way that we must worry about nuclear physics. Synthetic biology means an end to the age of innocence for the life sciences. "

  • Comment number 9.

    As a species we are destined to push forward to create life and who knows in another 100 years people may never get disease or die because of the bit of history we are discussing today.

  • Comment number 10.

    We know from history that just introducing an existing animal from one country into another can have devastating consequences for the local ecosystem: I worry about the potential damage a new organism could do that doesn't have any built in 'destruct' button. What if a bug designed to 'eat' greenhouse gases evolves after a few years into something with a taste for oxygen?

  • Comment number 11.

    Anything that advances the understanding of science is a good thing; it's only the intent that's bad!

  • Comment number 12.

    Before this study continues we need to be sure that the "bacteria" doesn't mutate like all other organisms in this world do. We all know computers have flaws. This scientist is just in way over his head and he needs to slow down. This could do more harm than good. This could be a step toward ending global warming or it could be a step towards mind control. Watch out it is 1984 all over again.

  • Comment number 13.

    The science is very exciting. I'm all for it continuing. However, this science like GM, will be controlled by Corporations. We must some day develop the 'biological wheel' for mankind to take it's next big step to the saving ourselves.
    We keep getting promises of the desert blooming, and no possible risk of cross contamination. We end up with plants locked into one breeder and one type of herbicide, only a marginal advantage in yield, and herbicide resistant weeds everywhere. I would recommend that this technology stays firmly under the control of the Government until it's uses and problems have been determined.

  • Comment number 14.

    Whatch out not too long before the drug companies will be letting synthetic bacteria loose so they can sell drugs to cure the effects. Now that smacks of conspiracy theory but we shall have to wait and see.

  • Comment number 15.

    Created by man. They evolved. They rebelled. There are many copies. And they have a plan......

  • Comment number 16.

    Scientific creation of life is procreative and inspired. Technology opens the future to all possibilities.

  • Comment number 17.

    Synthetic Biology is about developing non-natural organisms that do something desirable that does not occur in Nature. There are lots of problems that nature has not yet had to solve (for instance the large scale production of anti-malarials) that it is of use for humans and many cases where we can improve on the solutions to specific problems that Nature has found (Nature stops refining its solution once survival is ensured). The one thing, however, that Nature does all but perfectly is evolve and adapt. Synthetic organisms will find it impossible to thrive in the real world, full as it is, of organisms competing ferociously, using every trick developed over millions of years to get the jump on their rivals. The overwhelming likely fate of a synthetic organism released into the wild is to become a quick snack!

    @ #3 Hairy Dog

    If you really think bacteria reproduce by mating with one another then I don't think you've got a right to comment on this topic.

  • Comment number 19.

    Great idea. Nothing can be uninvented so it's hardly worth arguing about.

  • Comment number 20.

    An incredible advancement indeed, and a step closer to science-fiction! I think much good can come of this, BUT!!! I do have my fears. How will this affect the ecological balance? We've seen that introducing species from one place to another (think earwigs or frogs) can cause devastating effects. Natural species are one thing, artificial species are another altogether. Growth rates, natural 'predators', mutations will definitely have to be investigated. Furthermore, accidental contamination could potentially cause catastrophes. What if these 'artificial life-forms' were the missing link for a new pandemic or new diseases to develop? I do not discredit this discovery, I just think we're one step closer to playing God, human creationism, and that might not be the best of things if we don't God's knowledge along with it. Elsewise, mistakes will surely happen. 'Artificial' life could have very little repercussions, or very large ones on our natural environment.

  • Comment number 21.

    We won't know the effects until it's actually 'out there', and not at this
    embryonic (no pun intended) stage.

  • Comment number 22.

    Ah, I can already hear the hysterical wails from the superstitious european anti-genetically-modified food crowd all the way across the pond. But I bet the obligatory HYS remarks from hand-wringing, human-loathing, earth-is-too-important-to-have-to-support-subsistence-living-peasants zealots can't top this one: Lets hope that when this BIG GENETICS technology gets out of control Mother Earth can use it as a defensive weapon to purge earth of the vile human species.
    Why do the human-loathers who gleefully imagine there is a wise and loving (yet oddly vengeful) earth with magic powers refuse to believe that maybe human intelligence can make life better for the peasant majority. Isn't it more humanistic to help them than wishing they were terminated? Not too long ago anti-nuclear power zealots prevented new plant construction in the US. Now they are realizing that the environmental harm, human health problems (and deaths) caused by coal, oil are far worse. Imagine that...zealots learning that considerng all sides of an issue is essential.

    Fantastic achievement... but just because we can does not mean we should.

  • Comment number 28.

    Any technology breakthrough is a good thing for mankind as some breakthroughs in military science help in peaceful ways and improvements in peaceful technology can be used military applications. It's not the technology that causes harm but people and we shouldn't be worried about the technology just the people in charge.

  • Comment number 29.

    With any new technology, there will always be some nut case looking to use it to cause harm. That's what happened with nuclear technology, but we didn't all die in the cold war did we? Whilst genetic engineering can be powerful, using biological weapons like that is like using nuclear weapons: it can only end in mutally assured destruction.

    This technology is in it's infacy, however, and as such it would be foolish to try daring experiments at this stage. Research needs to be given time, and should not be bent by the popular press or otherwise. I do hope to see some good developments from it, including biological computers that can run much faster than our current silicon based technology.

    I guess I am one of those 'the glass is half empty' types.. I can't help but think this is one of those scientific breakthroughs that will end up being used to cause more harm than good. I am sure there are governments out there already trying to figure out a way to weaponize this new technology.

  • Comment number 32.

    It is a technical advance in bacterial transformation joining large lengths of DNA.. All that it represents is a verification of the fidelity of a DNA synthesizer and that of the sequencing technique for obtaining the complete DNA sequence from the original target bacterium. For years it has been possible to clone circular DNA resembling bacterial plasmids in bacteria. An completely 'original' designer genome has not yet been made and is probably not worth doing. New 'life forms' will be existing bacteria, plants and animals incorporating further catalogues of genes foreign to them. IN other words, new genetically modified organisms.
    The danger posed by transgenes is already real. It is feared that resistance genes incorporated into crop plants like cereals that allow them to live after exposure to herbicides like glyphosate may yet be naturally transfered to weeds.
    'Darth' Venter, the author of this latest piece of research, has been more interested in patenting human genes and selling the human genome database than in pure research and this too is for commercial application.

    Don't panic, Mr Mainwaring!

  • Comment number 33.

    Very exciting prospects here, but how do we keep this knowledge in safe hands? It's inevitable that eventually people with the knowledge and other bad ideas will have big plans.

    Guess it's the same with everything though really, so I say go ahead with it, the people that would abuse this 'technology' would just abuse some other tech if this didn't exist.

    Just thoughts aloud.

  • Comment number 34.

    I'm not sure what all the fuss is about. What Dr Ventner has done is the biological equivalent of typing the words from a book into a word-processor and printing it out again - then calling it a new book..!
    What would be significant would be to string together genes from different bacteria and create a totally new species - the equivalent of combining different pages from a whole library of books into a totally new that would be something to be concerned about..!

    I have to smile as this reminds me of a sketch from Only Fools and Horses. Del goes to the doctors and says to the lady doctor "I got a bit of Synthia." The doctor replies "I don't know that one!" Del explains he's suffering from a pain" Oh well I enjoyed it!

    Read "The Doomsday Book" by Gordon Rattray Taylor to see where scientific experiments with the environment either did go horribly wrong or had the potential to do so had they been carried through (as in the idea for flooding the Amazon Basin).

  • Comment number 61.

    When I read the headline I could not believe that the science was so developed that scientist can actually "build" cells.. But after reading it, though, I think it is the first step toward this.

    Besides all the risks and benefits we can see from this breakthrough, we should not forget that mutations can exist. The cells "are not perfect" and they won't replicate DNA always with 100% probability of success! Therefore I urge the scientist to clarify or at least investigate that the synthetic DNA will not cause a virus that can indeed destroy the humanity..

    We have so many problems with the CO2 and Acidification of the Oceans, that if these do not destroy Humanity (because we finally agreed on clima change and Global Warming), then, if such experiments get out of control, mutations could create a super power virus that might do it..

    Please note, I am a scientist myself and I am not against this breakthrough; just want to point out risk and risk mitigation..

    Remember this from 'Engines of Creation' by Eric Dexler? 'Imagine such a replicator floating in a bottle of chemicals, making copies of itself....the first replicator assembles a copy in one thousand seconds, the two replicators then build two more in the next thousand seconds, the four build another four, and the eight build another eight. At the end of ten hours, there are not thirty-six new replicators, but over 68 billion. In less than a day, they would weigh a ton; in less than two days, they would outweigh the Earth; in another four hours, they would exceed the mass of the Sun and all the planets combined - if the bottle of chemicals hadn't run dry long before.'

    There are certainly side effects and consequences both good and bad that have been overlooked or remain undiscovered. Before we start talks of developing fuels and medicine out of "synthetic life" cells, let's find out as much as possible about the effects on the environment and public health.

  • Comment number 70.

    For me, as someone who works in the field of genetical engineering, it doesn't seem to be much of a breakthrough, they just synthesized an artificial chromosome based on a working DNA. If they really created artificial life, they would have to suggest DNA coding proteins that are necessary for cells to "live". So, some boasting about this (considering it showed as a BBC top headline) is not really appropriate, basically it is conformation that bacterium whose DNA was removed, can "live" after addition of synthetic DNA with the same primary structure.

  • Comment number 71.

    This was solely synthetic DNA, which has been done before. A synthetic cell was the challenge! Please check your sources. Why is this even news?

    When someone makes synthetic machinery to read normal DNA (as a cell) I'll be impressed - now that would be a disruptive technology!

    Heck, when someone at least figures out how proteins fold without a brute force method, well, it's over our head for at least 20 years even there.

  • Comment number 75.

    One has to wonder how different (in terms of sequence)how different the in vitro synthesized DNA is compared to the DNA that was in the cell naturally to begin with. If the overall sequence is very similar to the DNA originally, then this might not be such a large development.

    This is great if controlled very carefully and within certain limits because we all know Bacterias will change and adapt to their environments such as Influenza, the Common Cold, Bird Flue etc.

    Like many such developments in Science, if used for GOOD it can benefit mankind, but take into account we are already over populated by some 2-2 Billion people worldwide for the amount of Land, Fresh Water and Natural Resources now, we really cannot afford to have loads of 'miracle' cures and we need to get used to the fact we NEED to die in order to PRESERVE life for millenia.

  • Comment number 78.

    Any cells that could be made in the lab could also happen in a similar if not identical form in nature. It is no more unnatural than synthetic medicines, HRT, fertility treatment or an artificial hip. We need to be careful and we need to make sure that mother nature remains in control but even while taking that into account we should not shy away from new developments.

  • Comment number 85.

    This is all just a little bit frightening for the likes of me. While my heart leaps at the possibilities it offers it also sinks at the thought of mankind actually being the creators and not the created.

    Does this mean we supercede God or are we merely being loaned this power until the Almighty decides he/she has given us enough rope and we are about to hang ourselves.

    This stupendous move to create life albeit synthetically should be closely monitored for it has the potential to outgrow the ethics of the scientists working on it. This is either the beginning of the end or the end of the beginning.

    Does anyone else remember the man who used to walk around with bill boards around his neck warning 'The End Is Nigh'. Now he really could be sane after all.

    I hope and pray that this a move for the betterment of mankind and lives up to the hyperbole surrounding it.

    It is undoubtedly a breakthrough, whether for good or bad remains to be seen. This science has the potential to alleviate disease and suffering, and that must be for the good. It also has the potential to degrade the very sanctity of life. As a Spiritualist I am not against this research per se, because whatever man is capable of is only because that capability has been given by God. But it is absolutely essential that progress in this field is accompanied every step of the way by full and open moral debate.

    Science is now progressing exponentially but too often scientists push boundaries because they can and with no regard for consequences, witness nuclear and other weapons of mass destruction. Universities need to think carefully about making moral ethics a compulsory component of every science course.

    - Can it currently be killed by common antibiotics?
    - Is it impossible for naturally occurring bacteria to initiate a gene swap between themselves and this new synthetic bacteria?
    - Is it impossible for the genome to mutate?

    Unless the answers to all those questions is "yes", then we could have a big problem.

    Of course natural bacteria have had millions of years to evolve very complicated set of genes. We have had a similar amount of time to evolve defences. However, as this synthetic DNA effectively bypasses evolution, the danger is that someone will inadvertently give it a payload that will be devastating.

    Creating synthetic life is a step in the direction of the ficticous Dr. Frankenstein, and is something that scares me and horrifies me.

    Whislt I am sure the creator Dr Craig Venter and his team are thinking of the good such synthetically produced 'life' can bring, I do wonder about the serious implications if something should go wrong or fail in the self reproducing genome as the cells reproduce.

    The whole thing could easily fall into the wrong hands, rogue states, terrorism, it really doesn't bear thinking about, there is a serious ethical question here, just merely monitoring what goes on may not be enough.

    On another scale it could be a little like the planting of genetically modified seeds, at a nice little profit to the seller of course, harmless enough in themselves as the crops grow (so far), in England it was considered that a ten metre gap between genetic and non-genetic crops would be enough to stop any cross polination (which is supposed to be impossible)

    However, the powers that be ommited to take into account the humble honey bee and bumble bee, who went busily on their way unable to read the signs "No bees betond this point", joke? No, on the contrary, quite serious, the intellegence of some of the ministry men is quite staggering, the honey you had this morning, was it natural pure - are you 100% sure?.

    To date there are a mix of genetic and non genetic crops growing following the cross polination in Mexico, which should all have been ordinary non-genetically modified, some of which have turned up in rainforests, not to mention the effect on UK crops and wildlife - where will this lead is anyones guess, but to play around with synthetically created life I think is a step far too far. No, emphatically no, it should be stopped.

    I made a little illustration:

    As with most scientific breakthroughs, this development is a two-edged sword. Those who made it have cited the potential benefits, which could be huge. But this technology in the wrong hands or even if there is some sort of accident could end up decimating humans if it becomes a dangerous pathogen. Unless development somehow tags it with markers which human defence systems recognise or it cannot reproduce or evolve to reproduce, humans and also animals will have absolutely no resistance to infection by it.

    There is one ethical question I want to raise and that is, do we have the right to patent life? (not this creationism v evolutionary which everyone is commenting on).

    I am think it has been a wonderful achievement to recreate a bacterial life form artificially in vitro. I'm sure the details of which genes were used will come out in years to come.We must remember that bacteria are a lot simpler genetically than us humans and in any environment outside a laboratory they are likely to be genetically different than when they started.

    I agree with the ethics involved in this are huge (we kill bacteria all the time by washing) especially if they start generating artificial eukaryotes (which make us up). I also voice my concerns with the obvious bad thing that can come out of this, I hope it doesn't happen.

    Happy debating!

    38.....Note to self...Wrong about Einstein quote, was Oppenheimer who said that,apologies for my subsequent confusion,thank you grey animal for spotting my error.Must do better next time,no mistakes or confusions allowed. 'fraid I got mixed-up..I will try to ensure it does not happen again.Once more,Thank you for your vigilance....sincerely,Aristotles23

    You can't stop the human race from advancing. I think these silly bioethics people just want something to protest about sometimes.

    This is the beginning of the end. I don't need to emphasise the dangers as other posters before me have done an excellent job.

    In addition, I do not regard the incorporation of synthetic DNA in a living organism as synthetic life. Synthetic life has to be 100% synthetic and this organism consists of a biological host bacterium with a synthetic genome. This is not artificial life. To qualify the host HAS to be totally artificial as well as having no biological content. The implications however are horrendous!

    Breakthrough? Maybe.. We're still pretty much living with the terror of companies with patents on genes that limit relative research, along with genetically modified crops that go into food without us knowing about it, producing god knows what results (as long-term effects have not been researched enough, due to haphazard research methods and non-existent unbiased monitoring organizations) and destroying the planets plant variety in the meantime. And now microbes.. though I can see the potential coming from it, I still cant help thinking "whats next? labeled flu? "made in blabla" or killer bacteria? (which gives a whole new meaning to future biological warfare amongst the "good" that might come from it)...

    No matter what the advance in science, there will always be strident voices saying it is a disaster, against God and the beginning of the end of civilsation, but these self same critics of research will quite happily take beneficial medicinal drugs and submit to life saving operations.

    None of the nay sayers had as much a negative impact as the bastion of right wing fundamentaalism, George W. Bush, who banned stem cell research that could lead to a cure for many disabled people.

    Should religious fundamentalism impede medicine? Not in a civilised modern world.
