  • Ben Stein loses all intellectual credibility

    On his blog Stein espouses one of the weakest attacks I’ve heard yet against evolution, and not even original. It’s a pathetic set of logical fallacies. Basically, he starts from the assumption that scientific theories arise if they serve the prevailing ideology of the time period, and because “Darwinism” was developed during the Victorian/imperialist age, it represents nothing but the worst aspects of that era.

    Let’s make this short and sweet. It would be taken for granted by any serious historian that any ideology or worldview would partake of the culture in which it grew up and would also be largely influenced by the personality of the writer of the theory.

    In other words, major theories do not arise out of thin air. They come from the era in which they arose and are influenced greatly by the personality and background of the writer.

    Darwinism, the notion that the history of organisms was the story of the survival of the fittest and most hardy, and that organisms evolve because they are stronger and more dominant than others, is a perfect example of the age from which it came: the age of Imperialism. When Darwin wrote, it was received wisdom that the white, northern European man was destined to rule the world. This could have been rationalized as greed-i.e., Europeans simply taking the resources of nations and tribes less well organized than they were. It could have been worked out as a form of amusement of the upper classes and a place for them to realize their martial fantasies. (Was it Shaw who called Imperialism “…outdoor relief for the upper classes?”)

    But it fell to a true Imperialist, from a wealthy British family on both sides, married to a wealthy British woman, writing at the height of Imperialism in the UK, when a huge hunk of Africa and Asia was “owned” (literally, owned, by Great Britain) to create a scientific theory that rationalized Imperialism. By explaining that Imperialism worked from the level of the most modest organic life up to man, and that in every organic situation, the strong dominated the weak and eventually wiped them out,

    Darwin offered the most compelling argument yet for Imperialism. It was neither good nor bad, neither Liberal nor Conservative, but simply a fact of nature. In dominating Africa and Asia, Britain was simply acting in accordance with the dictates of life itself. He was the ultimate pitchman for Imperialism.

    Alas, Darwinism has had a far bloodier life span than Imperialism. Darwinism, perhaps mixed with Imperialism, gave us Social Darwinism, a form of racism so vicious that it countenanced the Holocaust against the Jews and mass murder of many other groups in the name of speeding along the evolutionary process.

    Wow. There are so many fallacies here I don’t know quite how to start. For one, if one assumed that his assumptions were correct, this would just be a genetic fallacy. But since we know this is absurd, and that evolution has persisted as a theory because of the consistency of the theory with observation of the natural world, we can reject this idiocy out of hand. But then he devolves into the fallacy of appeal to consequences – again based on false premises. Including the pathetic Darwin lead to Hitler canard. Again, even if this were true, it would be like saying we shouldn’t believe in physics because it leads to nuclear weapons. However, it decidedly isn’t true, and as we’ve discussed previously, is based on a disingenuous reading of history that the ADL has attacked as disturbing tactic to try to shift blame for the holocaust from anti-antisemitism to science. This is a doubly disgusting tactic. It attempts to shift the blame for the holocaust away from the antisemitic ideology of Hitler and Nazism (suggesting antisemitism is scientifically justified by evolution!), while simultaneously trying to exploit the victims of the holocaust for the benefit of the anti-evolution cause. Stein should be ashamed.

  • The Origin of HIV in the Americas

    Blogging on Peer-Reviewed ResearchThe mainstream media has been reporting on this paper (open access at PNAS) on the hunt for the origin of HIV in the Americas.

    The surprising result was the finding that HIV first came to the United States from Haiti (rather than the previous origin which was thought to be a flight attendant from Canada) between 1966 and 1972, and flew under the radar of public health authorities for over a decade. The infection, spread initially by heterosexuals from Haiti, went undetected from as early as 1966 until 1981 and then only because it had jumped into a highly susceptible population. This article is rather humbling, because in perhaps the medically advanced country in the world, it evaded detection for so long until it finally created an epidemic in the male homosexual population.

    So how did they figure this out?

  • Animal Rights Extremists Wreck Scientist's House

    The latest pathetic assault on a scientist came from ALF against UCLA scientist Edyth London. Using a garden hose they flooded her home, causing tens of thousands in damage. However, rather than intimidating her out of performing research in addiction she has written an article for the LA Times, defending animal research.

    For years, I have watched with growing concern as my UCLA colleagues have been subjected to increasing harassment, violence and threats by animal rights extremists. In the last 15 months, these attempts at intimidation have included the placement of a Molotov cocktail-type device at a colleague’s home and another under a colleague’s car — thankfully, they didn’t ignite — as well as rocks thrown through windows, phone and e-mail threats, banging on doors in the middle of the night and, on several occasions, direct confrontations with young children.

    Then, several weeks ago, an article in the San Francisco Chronicle about the work I have been doing to understand and treat nicotine addition among adolescents informed readers that some of my research is done on primates. I was instantly on my guard. Would I be the next victim? Would the more extremist elements of the animal rights movement now turn their sights on me?

    The answer came this week when the Animal Liberation Front claimed responsibility for vandalism that caused between $20,000 and $30,000 worth of damage to my home after extremists broke a window and inserted a garden hose, flooding the interior. Later, in a public statement addressed to me, the extremists said they had been torn between flooding my house or setting it afire. Maybe I should feel lucky.

    Having come to the United States as the child of Holocaust survivors who had lost almost everything, I appreciate that perhaps “only in America” could I have fulfilled my dream of becoming a biomedical scientist, supported in doing research to reduce human suffering. But it is difficult for me to understand why the same country that was founded on the idea of freedom for all gives rise to an organization like the Animal Liberation Front, a shadowy group identified by the FBI as a domestic terrorism threat, which threatens the safety of researchers engaged in animal studies that are crucial to moving medicine forward.

    I have devoted my career to understanding how nicotine, methamphetamine and other drugs can hijack brain chemistry and leave the affected individual at the mercy of his or her addiction. My personal connection to addiction is rooted in the untimely death of my father, who died of complications of nicotine dependence. My work on the neurobiology of addiction has spanned three decades of my life — most of this time as a senior scientist at the National Institutes of Health. To me, nothing could be more important than solving the mysteries of addiction and learning how we can restore a person’s control over his or her own life. Addiction robs young people of their futures, destroys families and places a tremendous burden on society.

    Animal studies allow us to test potential treatments without confounding factors, such as prior drug use and other experiences that complicate human studies. Even more important, they allow us to test possibly life-saving treatments before they are considered safe to test in humans. Our animal studies address the effects of chronic drug use on brain functions, such as decision-making and self-control, that are impaired in human addicts. We are also testing potential treatments, and all of our studies comply with federal laws designed to ensure humane care.

    While monkeys receive drugs in the laboratory, they do not become “addicted” in the same sense that humans become addicted. Still, we are able to see how changes in brain chemistry alter the way the brain works — knowledge that is vital to the design of effective medications.

    My colleagues and I place a huge value on the welfare of our research subjects. We constantly strive to minimize the risk to them; however, a certain amount of risk is necessary to provide us with the information we need in a rigorously scientific manner. Since the incident at my house, our research has gotten a lot of attention. Some anti-smoking groups have raised questions about the fact that our work was funded by Philip Morris USA. Is it moral to allow the tobacco industry to fund research on addiction? My view is that the problem of tobacco dependence is enormous, and the resources available for research on the problem are limited. It would, therefore, be immoral to decline an opportunity to increase our knowledge about addiction and develop new treatments for quitting smoking, especially when teens are involved. Few people are untouched by the scourge of addiction in their friends or family. It is through work like ours that the understanding of addiction expands and gives rise to hope that we can help people like my father live longer, healthier lives.

    Thousands of other scientists use laboratory animals in other research, giving hope to those afflicted with a wide variety of ailments. Already, one scientist at UCLA has announced that he will not pursue potentially important studies involving how the brain receives information from the retina, for fear of the violence that animal rights radicals might visit on his family. We must not allow these extremists to stop important research that advances the human condition.

    Edythe London is a professor of psychiatry and bio-behavioral sciences and of molecular and medical pharmacology at the David Geffen School of Medicine at UCLA.

    The reason I consider animal rights extremists denialists is because like other ideologues with an anti-science agenda, they lie about science to accomplish their goals. They routinely assert there is no need for animals to be used in research, that animals don’t relate valuable information, or exaggerate claims and examples of abuse to malign scientists as a whole. That they also use physical intimidation, threats against scientists, and violence just makes them that much worse.

    By the way, students and faculty at Hampshire college in Amherst can do their part to stop terrorist groups like ALF by opposing their “Smash the state crush the cage” conference occurring next week.

    I’m sure my other sciencebloggers will agree (unlike the cranks who do no science and presume to tell us our business) that animals are critical for biomedical research. We need to stand up to intimidation and not just attack ARAs when they stoop to violence, but when they misrepresent science and animal research as uneccessary. Groups like Americans for Medical Progress are a good start. But I would like to see scientists and sciencebloggers explain why they use animals and how it is critical for the scientific enterprise. The problem is, by trying to keep our animal work out of the spotlight, it’s made it appear as though we have something to hide, and has confused the public about the critical role of animals in biological research. We need to reverse this trend and inform people so they know that what we do in the lab using animals ultimately benefits humans knowledge in way that saves lives.

    I’ll start. I use knockout animals, you know, that unimportant little technology that won the Nobel Prize this year. I use it to study the function of a gene that may be critical for heart development, is involved in pathological hypertrophy and appears to have the capability of turning on the cardiac developmental program in stem cells. One future use is a combined therapy potentially benefiting patients post-myocardial infarction with an autologous stem cell transplant of mesenchymal stem cells activated with this gene. A long way from bench to bedside, but the studies in animals have so far been pretty exciting.

    Consider this a tag. If you do science and use animals in research explain on your blog and link back here. No blog? Tell me in the comments.

    Update: Two of my scienceblogger colleagues have already recommended their extensive writings on the topic:
    Nick Anthis and
    Bora.
    But I’d still like to hear from the people who actually do research (you’ll find the sentimental nonsense and hand-wringing mostly from those that don’t) about how animals are necessary for your work, and why you think your work is important. Don’t be afraid to share.

    Update 2: Nick Anthis has even more, and for anyone who is foolish enough not to think this is terrorism, read his post and tell me you still think it’s just a prank.

    Update 3 ERV contributes to the cause and brings up the point of the importance of clonal or inbred populations.
    Shelley at Retrospectacle contributes her 2 cents. As does Orac.

    Update 4 – PZ weighs in, Angrytoxicologist gives us a Karmic pass.

  • Fight on Phenomenon!

    Last week you may remember I watched phenomenon with eye out for Uri Geller’s nonsense, and I was pleasantly surprised to find Criss Angel playing the skeptic pretty well.

    Well this week’s was awesome! Jim Callahan does a pretty cheesy psychic bit, with some really terrible acting, and it’s so bad that Angel calls him out. Angel starts demanding he (or Geller) show real psychic ability and if he did he’d give him a million dollars. It ends up with them being physically separated – check it out!

  • Ask A Scienceblogger – Which parts of the human body could you design better?

    i-133b9fea8ea6b307d8c9133b7f3e23bf-dice.jpg The question this month is “Which parts of the human body could you design better?”

    This is a great question, because a lot of aspects of the human body represent what worked well enough for survival, not necessarily what works best. Therefore the engineering ends up being rather ramshackle, and convoluted, and sometimes, downright terrible.

    For instance, who can look at this image – an anatomical model of human pregnancy at term, and not think this is really, really stupid engineering.

    i-ec01c2239e3d4a89de41331d214c2397-Female reproduction.jpg
    (image via wikipedia)

    The very first thing I would change would be the female reproductive system. Ideally reproductive systems and waste removal equipment shouldn’t share space or have a such proximity to each other increasing risk of infection. The pelvis could do with some widening so women could actually deliver kids without killing themselves a significant portion of the time. Further, pregnancy in humans results in a fetus sitting on the bladder and colon for several months (and vaginal delivery acutely injures these muscles), as a result, post-partum many women have difficulty with urinary incontinence, and with age and with more kids the greater the risk of incontinence (this can not be prevented by c-section – so the damage is likely from positioning of the fetus on top of the bladder rather than acute trauma during birth). This unfortunate arrangement of the uterus appears to be a result of the change from walking on all fours to walking upright, the fetus, which would ordinarily sit mostly on the wall of the abdomen, ends up sitting directly on internal organs.

    I’m sure women would like an alternative to monthly period as well. Overall though, the female reproductive system is terrible, involving significant risks of morbidity and mortality with each pregnancy. One of the great benefits of medicine has been the drastic reduction in infant and maternal mortality with labor and delivery – but it would be nice if the system were engineered correctly in the first place.

  • Ugly Teeth and consumer protection

    Another sign the monkeys are running the zoo is the news that the head of consumer protection doesn’t want consumer protection.

    The top official for consumer product safety has asked Congress in recent days to reject legislation that would strengthen the agency that polices thousands of consumer goods, from toys to tools.

    On the eve of an important Senate committee meeting to consider the legislation, Nancy A. Nord, the acting chairman of the Consumer Product Safety Commission, has asked lawmakers in two letters not to approve the bulk of legislation that would increase the agency’s authority, double its budget and sharply increase its dwindling staff.

    Ms. Nord opposes provisions that would increase the maximum penalties for safety violations and make it easier for the government to make public reports of faulty products, protect industry whistleblowers and prosecute executives of companies that willfully violate laws.

    The measure is an effort to buttress an agency that has been under siege because of a raft of tainted and dangerous products manufactured both domestically and abroad. In the last two months alone, more than 13 million toys have been recalled after tests indicated lead levels of almost 200 times the safety ceiling.

    Ms. Nord, who before joining the agency had been a lawyer at Eastman Kodak and an official at the United States Chamber of Commerce, criticized the measure in letters sent late last week and this afternoon to the Democratic leaders of the committee. She was critical, for instance, of a provision to ban lead from all toys. She said that the proposal to raise the potential penalty to $100 million “may have the undesired consequence of firms, as a precautionary measure, flooding the agency with virtually every consumer complaint and incident.”

    Now, match this news with the latest news on Halloween plastic teeth.

    Based on the inquiries by CBS News and the complaint filed with the Consumer Product Safety Commission, there is now an official investigation into why some “Ugly Teeth” have levels of lead 100 times beyond the legal limit.

    There are thousands of these fake teeth, which have been purchased in the past few days as part of the ghoulish outfits of tiny trick-or-treaters around the country. Lead is dangerous if ingested, and extremely dangerous to small children.

    The proportion of products that Professor Jeff Weidenhamer found to have high lead levels is what troubled him. Out of 56 Halloween-related products he tested, he found six to have levels between four and 130 times what is allowable. All 6 of the products with these problems were made in China.

    I love the irony.

    The teeth are supposed to make you look stupid. The irony is, with all the lead in them, they may actually make you stupid.

    How fortunate we are that we have yet another incompetent or downright crooked Bush appointee in place to ensure that our critical regulatory agencies don’t do their jobs.

  • Now I can't wait to see the Golden Compass (what kind of daemon do you have?)

    It’s already got the fundamentalists up in arms. Apparently, one of them managed to read something outside the accepted cannon of Christ-like books and now they’re all bothered about the December 7th release (see trailer) of the first installment of Phillip Pullman’s His Dark Materials trilogy – the Golden Compass (IMDB).

    According to CNSNews.com, leading atheist writers and intellectuals are engaged in a “scientific” quest to ultimately destroy organized religion, particularly Christianity. Oxford professor Richard Dawkins, author Sam Harris and journalist Christopher Hitchens are some of the big names leading this “new atheism” initiative. Evidence of their agenda is seen in efforts such as the Out Campaign and the Blasphemy Challenge.

    Pullman’s book trilogy is the story of “a battle against the church and a fight to overthrow God,” BBC News reported. The Guardian, a British newspaper, goes even further to describe the books as “metaphysical fantasies encompassing parallel worlds, the death of God and the fall of man ….”

    Therefore, without yet seeing the film, at least one pro-family group — the American Family Association — is alerting Christians to the potential dangers of The Golden Compass. Because of Pullman’s clearly articulated anti-Christian motives, AFA is warning all viewers to run from the film.

    The Golden Compass is set in an alternative world with a sinister Magisterium. It is about a girl named Lyra who sets out to rescue her friend Roger who has been kidnapped by an organization known as the Gobblers. Roger’s rescue turns into an epic quest to save two different worlds — one in which people’s souls manifest themselves as animals. These manifestations are known as “daemons,” and Pullman says they help a person grow toward wisdom.

    In addition, the movie website allows visitors to answer a set of questions and create their own daemons that journey alongside them in life.

    “One of the [book] series’ main themes — the rejection of organized religion and in particular the abuse of power within the Catholic Church — is to be watered down,” according to the Telegraph, a newspaper in the U.K. “But when the film is released in December the Magisterium will be shown as a critique of all dogmatic organizations, thereby avoiding a religious backlash.”

    I’ve got to say I’m excited after seeing the trailer, because it looks beautiful, and it’s got damn good casting. Nicole Kidman is a perfect choice for Coulter (no not that one – don’t worry) Daniel Craig is an excellent choice, if a bit young, for Asriel, and Sam Elliot couldn’t be more fitting a choice for the Texan Lee Scorsby. Ian McKellen is even voicing Iorek.

    It’s a funny double-standard the AFA and others objecting, after all, if the Chronicles of Narnia is acceptable as a children’s movie despite the Christian dogmatism inherent in the plot (and purposefully placed their by C.S. Lewis), surely atheists are allowed to have a film that discourages dogmatism (purposefully placed their by Pullman). Isn’t it only fair? We’ll have a poll after this comes out, which is better. I found Narnia to be insipid and bland. Hopefully they won’t be to scared of offending the religious to give these films an edge.

    Either way, I can think of no better advertisement for a movie for kids than the AFA saying it’s bad for them.

    Here’s the site to design your daemon by the way. My daemon’s name isClymonistra, and she’s a tiger.

  • Doctors are conspiring to convince you you're sick!

    How do doctors decide what is healthy and unhealthy? Do they arbitrarily decide on risk factors to line their pockets – creating false epidemics as Sandy Szwarc at Junkfood Science suggests? Or, is there actually a science, called epidemiology, that is the basis for health recommendations?

    As I’ve said repeatedly, one of the sure signs you’re about to hear total BS is if someone suggests there is some conspiracy by scientists or doctors to hide the truth. In an article challenging the use of serum troponin levels to determine whether myocardial infarction (MI) has occurred (a more sensitive method) Sandy suggests this is yet another example of doctors lowering metrics of illness and risk to generate the impression of false epidemics.

    There must be a health crisis to bring the greatest funding for research, treatments and education… even if an epidemic has to be created. One of the most common tactics is to change the definition. When diagnostic criteria is broadened, suddenly, with the stroke of a pen, new cases can appear to explode in number.

    With heart disease deaths dropping dramatically for the past half century, the world’s top four organizations representing heart disease interests have all gotten together to change the definition … of a heart attack.

    The World Heart Federation, American College of Cardiology, American Heart Association and the European Society of Cardiology have been championing the new criteria over recent years, and will officially release it next month in the Journal of the American College of Cardiology and in the AHA journal, Circulation. The new definition will use elevations of troponin levels, rather than the traditional cardiac biomarkers, such as the MB-CK enzyme.

    This is a truly bizarre argument. Because measuring troponin will allow us to detect more MIs that have occurred, it must of course be part of a plot to make Americans think they’re less healthy. Never mind that more sensitive tests for MI are what is known as a good thing, and that current tests clearly are missing minor heart damage thus underestimating the number of true MIs. Any revision of current standards must be part of a plot! The fact that those scientists got together is a sure sign. We should never let them do that.

    While troponins may go up for other reasons, the idea that the test will misdiagnose as heart attacks other disorders is pretty silly. This isn’t a test that is going to be used to diagnose MI in the absence of chest pain or abnormal ECG findings – which enhances the specificity of the test – and doctors are aware of confounding diagnoses – it’s their job to find them. Further, the idea that the new criteria were designed to somehow justify funding for heart disease (an area of medicine that will never lack for funding) is downright hilarious.

    But this isn’t the only example of “false epidemics” being created by those greedy doctors trying to convince people that they’re ill. Sandy mentions other excellent examples.

    First, because this is Sandy, is of course obesity:

    “Overweight:”Definition changed from BMI ≥ 27 to BMI ≥ 25 by the U.S. National Heart Lung and Blood Institute in 1998, instantly increasing by 43% the numbers of Americans, an additional 30.5 million, deemed ‘overweight.’

    So, did doctors just pull that figure out of nowhere to line their pockets? Or does data exist that justify the decision? This study in NEJM(1) is a prospective study of over a million people evaluating all-cause mortality (as well as a number of independent risk factors) showing the relationship between BMI and mortality. Here is the relevant figure – the dark line is most relevant – showing the relative risk of death versus BMI.

  • Bloggers for Peer Reviewed Research

    BPR3, or Bloggers for Peer-Reviewed Research Reporting has announced the release of their new icons. For those of you who don’t know what this is all about, it’s pretty simple. When we’re not making up lolcats, and being all super-serious, we want to have a simple way to communicate to the audience that we’re discussing the scientific literature itself. That is, we’re not just reacting to idiotic press releases, poorly-written articles in major newspapers, or the latest misunderstanding of science by some crank. We’re actually reading the science before we pontificate about it.

    This should be encouraged. So here are my 6 posts I’ve attached the logo to so far. You may remember some of them.
