Three-parent embryo formed in lab (BBC NEWS)Scientists believe they have made a potential breakthrough in the treatment of serious disease by creating a human embryo with three separate parents. The Newcastle University team believe the technique could help to eradicate a whole class of hereditary diseases, including some forms of epilepsy. The embryos have been created using DNA from a man and two women in lab tests. It could ensure women with genetic defects do not pass the diseases on to their children. The technique is intended to help women with diseases of the mitochondria - mini organelles that are found within individual cells. They are sometimes described as "cellular power plants" because they generate most of the cell's energy. Faults in the mitochondrial DNA can cause around 50 known diseases, some of which lead to disability and death. About one in every 6,500 people is affected by such conditions, which include fatal liver failure, stroke-like episodes, blindness, muscular dystrophy, diabetes and deafness. At present, no treatment for mitochondrial diseases exists. Genetic transplant The Newcastle team have effectively given the embryos a mitochondria transplant. They experimented on 10 severely abnormal embryos left over from traditional fertility treatment. Within hours of their creation, the nucleus, containing DNA from the mother and father, was removed from the embryo, and implanted into a donor egg whose DNA had been largely removed. The only genetic information remaining from the donor egg was the tiny bit that controls production of mitochondria - around 16,000 of the 3billion component parts that make up the human genome. The embryos then began to develop normally, but were destroyed within six days. Appearance Experiments using mice have shown that the offspring with the new mitochondria carry no information that defines any human attributes. So while any baby born through this method would have genetic elements from three people, the nuclear DNA that influences appearance and other characteristics would not come from the woman providing the donor egg. However, the team only have permission to carry out the lab experiments and as yet this would not be allowed to be offered as a treatment. Professor Patrick Chinnery, a member of the Newcastle team, said: "We believe that from this work, and work we have done on other animals that in principle we could develop this technique and offer treatment in the forseeable future that will give families some hope of avoiding passing these diseases to their children." Dr Marita Pohlschmidt, of the Muscular Dystrophy Campaign, which has funded the Newcastle research, was confident it would lead to a badly needed breakthrough in treatment. "Mitochondrial myopathies are a group of complex and severe diseases," she said. "This can make it very difficult for clinicians to provide genetic counselling and give patients an accurate prognosis." However, the Newcastle work has attracted opposition. Josephine Quintavalle, of the pro-life group Comment on Reproductive Ethics, said it was "risky, dangerous" and a step towards "designer babies". "It is human beings they are experimenting with," she said. "We should not be messing around with the building blocks of life." Mrs Quintavalle said embryo research in the US using DNA from one man and two women was discontinued because of the "huge abnormalities" in some cases. Dr David King, of Human Genetics Alert, expressed concern about a "drift towards GM babies".
Story from BBC NEWS: La raison pour laquelle Justice de Thézier a quitté le mouvement transhumaniste (Justice de Thézier)Pour aider l'équipe de Théâtre Transhumain à mieux comprendre le transhumanisme, je poste ici la lettre par laquelle j'ai publiquement renoncé à mon adhésion à l'idéologie et mouvement transhumaniste ainsi que ma réplique à un membre de l'Association transhumaniste mondiale qui a écrit une critique de cette lettre: 'There is a large group of people out there, I think, who can be thought of as similar to Arjen and Justice. They were initially 'wowed' by transhumanism, ran about trying to get everyone interested, became increasingly dissatisfied for one reason or another, and then went off to do other things. These folks interpret their dissatisfaction and decision to disengage as evidence of inherent problems with transhumanism. "There's nothing wrong with me; it must be you." This is just a bald lack of self-criticality.'uh, since I clearly explained what was both "wrong with me" and transhumanism the accusation that I am not self-critical is quite strange. Keith continued: ‘There is ample evidence, written in Justice's own hand in his dramatic 'quitting' post, to show that he made the somewhat immature mistake of becoming enamored of an idea. There is further evidence to show he compounded this mistake by blaming the idea itself for his attraction to it.’I can't really say I became ''enamored'' with the *idea* of transhumanism (as opposed to the movement itself) since, like many transhumanists, I always held a ''transhumanist'' worldview without knowing there was a label for it. However, I did intellectually and emotionally invest myself in the transhumanist cause in the same way that I have invested in many other causes ranging from progressivism to environmentalism. If one remains critical, there is nothing wrong with such an act of investment. However, I found the transhumanist subculture tends to reinforce or ''pervert'' one's long-held or newly-found convictions, whether or not these convictions are sound. Keith continued: ‘Justice starts us off with a doozy, "When I discovered and read the (previous) ranshumanist FAQ of the World Transhumanist Association (WTA), . . . my life changed forever." Now, the two documents mentioned here are not stunning examples of literary excellence. In fact, they're somewhat dry, and written in a reasonable, factual tone. I see no exclamation points, no 'manifesto discourse'. It seems that it would take a little bit more than a basic statement of values, and answers to a few questions to change one's life forever, no?’Please forgive my rhetorical style and conciseness but I didn't mean to suggest that the Transhumanist FAQ alone literally ''changed my life forever''. I was suggesting that my agreement with the majority of the answers of the Transhumanist FAQ *and* my further reading of transhumanist literature as well as my conversations with some leading transhumanists but, most importantly, the very existence of an organization dedicated to goals I support led me to take a series of decisions which not only took my life in a different direction when it comes to my career but even contributed to me becoming a local celebrity of sorts (not that I was looking to become one...). On a regular basis, I walk down the street and get approached by people who recognize me as ''The Montreal Transhumanist''. If that can't be considered as evidence that one's life has changed forever, I don't know what can. ;) Keith continued: ‘Justice may not know it, but he describes himself as a person somewhat vulnerable to utopian 'future hype' -- oddly, the very same criticism leveled at transhumanists.’Ahhhh... Keith has unknowingly touched on the ''tactic'' behind my letter. When I decided to write it, I felt I had two choices. The first one would involve exhaustively naming all the prominent transhumanists and quoting all their public and private statements as evidence of the flaws of transhumanism. However, this would have enraged many people due to having possibly damaged their public credibility but, more importantly, it would have prevented them from listening to, and understanding, what I was trying to communicate to them by virtue of having put them on the defensive. The second one (which I chose) was to offer a personal narrative in which I attribute to myself views and behaviors that I had observed in many prominent transhumanists (rather than a few marginal ''rank-and-file'' transhumanists that are supposedly not representative of the transhumanist community...) which are views and behaviors that I quickly recognized in myself quite early on but proceeded to overcome. My assumption was and is that people are more likely to recognize these views and behaviors in themselves when it is presented to them through such an *allegory*. Keith continued: ‘Justice goes on explaining the source of his eventual dissatisfaction with transhumanism, "It also seemed that I was spending far more time trying to convert people to transhumanism..." Oddly, Justice characterizes his actions in pseudo-religious terms. Transhumanism isn't a cult, but Justice clearly made the mistake of thinking he joined one. Now transhumanists generally like to express their opinions on matters of technology, some even politics, and many prognosticate about the future. But nowhere did I see an exhortation to proselytize for converts. This is just a mistake Justice made, and rather than search out the aspects of his personality that led to this mistake, he would rather blame the ideology, or the community?’Although I did use the word ''convert'' to negatively imply that the actions of some transhumanists are pseudo-religious (For evidence, one just needs to read this infamous excerpt from a prominent transhumanist's evangelistic speech about transhumanism), many leading transhumanists have exhorted us to build the transhumanist movement by ''proselytizing for converts" in the same way that militant communists, feminists and environmentalists have done. This is a perfectly legitimate activity (and I admire them for their commitment to engaging in it). The problem is that, as a local chapter organizer, I found that not only was I and others engaging in too much of it but I no longer believe it will significantly and positively contribute to the techno-progressive struggle. Keith continued: ‘One plausible reason why Justice might have made this mistake could be that he has an intellectual tendency toward an us-them, tribe-like mentality -- another of the criticisms leveled at transhumanists.’Although I can't deny that I have an intellectual tendency to want to make people (uncomfortably) aware of a ''left''/''right'' political analysis of technodevelopmental politics (which I will promptly admit was unfair and inaccurate if and when it is shown to be), my criticism of the transhumanist ''us vs. them'' tribe-like mentality and identity is reflected in the much documented history of transhumanists falsely portraying both reasonable and unreasonable critics of ''enhancement technologies'' as critics of transhumanism (which are not the same thing) but, worse, dismissing them as ''luddites/neo-luddites/bioludites'' when most of them are not.Dale Carrico has written on this particular point in his essay The Trouble with ''Transhumanism'': Part Two. Keith continued: ‘However, here is the key paragraph in which Justice gives away the store, "... having invested so much time and energy in promoting transhumanism --- and let's be honest, having been seduced by the syren songs of a ''posthuman future'' --- I came to the awkward realization that I, a self-professed free and critical thinker, had willingly blinded myself to the flaws of transhumanism which I became increasing aware were inherencies that *undermine* any diversity of views or ''leftist awakening'' among transhumanists..." In this one paragraph, Justice summarizes his work for a tribe which only he thinks exists, reiterates his vulnerability to future hype, and admits his tendency to deliberately avoid self-criticism. In all, his entire quitting speech implies its author became enamored of an idea. It reads like a passionate story of unrequited love. And in the end, like all good tragedies, he blinds himself to his own foibles and instead projects them onto the source of his anguish and sees 'tragic flaws' in transhumanism where the indifferent audience sees only him.’Although essentially truthful, my letter does read like ''a passionate story of unrequited love'' purely for rhetorical purposes. As I explained above, I was attributing to myself the foibles of others in order for it to be easier for them to recognize it in themselves. The fact that many transhumanists and ex-transhumanists have privately and publicly expressed this recognition not only supports my criticism but validates my ''tactic''. That being said, if you remove the personal narrative in which I framed my critique of transhumanism, one is left with the exact same arguments that many people (some of whom transhumanists actually respect) have made, including Dale Carrico which he has exhaustively and eloquently expressed in his Superlative Summary, and even on the wta-talk list on December 15th:
That being said, even if all Carrico’s criticisms of transhumanism were demonstrated to be unfair and inaccurate, anyone who thinks that the transhumanist ideology and movement has been and is relatively flawless or does not deserve any of the criticism it has generated over the years is dangerously delusional. Publié par Justice De Thézier Hearts from cadavers beat anew: study (FRANCE PRESSE)Sun Jan 13, 5:25 AM PARIS (AFP) - In experiments that would make Dr. Frankenstein jealous, US scientists have coaxed recycled hearts taken from animal cadavers into beating in the laboratory after reseeding them with live cells, according to a study released Sunday. If extended to humans, the procedure could provide an almost limitless supply of hearts, and possibly other organs, to millions of terminally ill people waiting helplessly for a new lease on life. Approximately 50,000 patients in the United States alone die every year for lack of a donor heart, and some 22 million people worldwide are living with the threat of heart failure. "The idea would be to develop transplantable blood vessels or whole organs that are made from your own cells," said lead researcher Doris Taylor, director of the Center or Cardiovascular Repair at the University of Minnesota. While there have been advances in generating living heart tissue in the lab, this is the first time an entire, three-dimension bio-artificial heart has been brought to life. The core procedure making this possible is called decellularisation. In this process, all the cells from an organ -- in this case the heart of a dead rat -- are stripped away using powerful detergents, leaving only a bleached-white scaffolding composed of proteins secreted by the cells. In the experiments, this matrix was then injected with a mixture of cells taken from newborn rat hearts and placed in a sterile lab setting, where the scientists hoped it would grow. After only four days, contractions started, and on the eighth day, the hearts were pumping, according to the study, published in the British journal Nature Medicine. The researchers were stunned. "When we saw the first contractions, we were speechless," said Harald Ott, a surgeon at Massachusetts General Hospital. "We certainly were surprised that it worked so well and so quickly," Taylor told AFP. "There are so many places this could have gone wrong." In humans the objective would be to inject stemcells drawn directly from the recipient of the donated organ, thus eliminating the danger that the new heart would be rejected by the immune system. Recent breakthroughs in stemcell research from non-embryo sources mean that new tissues should be easy to generate, according to the authors. Many patients who might one day benefit from a transplanted bioartificial organ are currently not even listed as potential recipients, said Ott. "If organs derived from a patient's own cells would become available on a large scale -- maybe even as an off-the-shelf product -- millions of patients suffering from organ failure would benefit," he said in an e-mail. In these "proof of concept" experiments, the bioartificial rat hearts grown in the lab pumped, after eight days, with a force equivalent to about two percent of an adult rodent heart. Taylor and her team are now working on making the recycled organs more efficient, and have even transplanted some of these hearts into the abdomens of rats and connected them to the animals' aortas, a standard way of testing whether a donor organ can keep an animal alive. Decellularisation could change the way scientists thinks about engineering organs, according to the study. "It opens a door to this notion that you can make any organ: kidney, liver, lung, pancreas -- you name it and we hope we can make it," Taylor said. Though not reported in this study, the Minnesota researchers have also successfully applied the technique to pig hearts, which are closer to human hearts in size and complexity.
Olympics ban for S African "Blade Runner" Pistorius (FRANCE PRESSE)Mon Jan 14, 9:14 AM PARIS (AFP) - South African paralympic champion Oscar Pistorius has been told he cannot compete in the Beijing Olympics because the artificial legs he uses give him an unfair advantage. The decision to ban the 21-year-old sprinter from all competitions involving able-bodied athletes was announced by the sport's governing body, the International Association of Athletics Federations (IAAF) on Monday. Pistorius, who as an 11-month-old baby had both of his legs amputated below the knee due to a congenital disorder, runs on specially adapted carbon fibre blades that have seen him win paralympic titles and challenge the times set by top-level able-bodied athletes. But a scientific investigation into his springy prosthetics carried out by the Institute of Biomechanics at Cologne University last November found that they gave him a clear competitive edge over such athletes. The results of these tests were handed over to IAAF president Lamine Diack last week and he asked his 27-strong executive council to make a ruling. A statement from the IAAF said that the Cologne tests had involved comparing the running efforts of Pistorius against that of five able-bodied athletes who are capable of similar levels of performance at 400 metres. "Pistorius was able to run with his prosthetic blades at the same speed as the able bodied sprinters with about 25 percent less energy expenditure," the IAAF statement said. "As soon as a given speed is reached, running with the prosthetics needs less additional energy than running with natural limbs. "The IAAF Council has been able to review the full report and has decided that the prosthetic blades known as "cheetahs" should be considered as technical aids in clear contravention of IAAF Rule 144.2. "As a result, Oscar Pistorius is not ineligible to compete in competitions organised under IAAF Rules." Pistorius, dubbed by the press as the "Blade Runner", has already taken part in major IAAF-sanctioned events such as last July's Golden League meeting in Rome, and he has made it clear his dream was to compete at this summer's Beijing Olympics, possibly in the South African 4x400 metres relay team. The South African denies he gains an unfair advantage over his rivals and he has already said that he will contest any ban imposed by the IAAF on his racing activities. "I feel that it is my responsibility, on behalf of other disabled athletes, to stand firm," he said. "I will appeal [against] this decision at the highest levels, while also continuing with my quest to race in the Paralympic Games and hopefully the Olympic Games." Pistorius, currently studying business management at Pretoria University, embarked on his running career only three years ago while jogging during his recuperation process after breaking a knee in a rugby match. He soon swapped the rugby field for the track and has never looked back, breaking paralympic world records on 19 different occasions. His running blades are made in Iceland at a cost of 12,000 euros. .
