  • Two links for you

    So nothing special for today, I’m too busy with meatworld, but you might enjoy these two links:

    Teen sex has been wronged by a puritanical society – it appears teens who have sex earlier are less likely to become delinquents (however I suspect it ignores that they are also more likely to get knocked up). This makes sense to me though. Why bother with drugs, crime, and other delinquent behavior when you’ve got sex?

    Second we have news that Chiropracters might also be useless for back pain. Ouch, now that hurts. The last thing left to chiropractors that seemed to have any validity (subluxation as a cause of disease certainly doesn’t) might be lost to them. Also, check out the defensive explanation from the British Chiropractor – sound familiar?

  • 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.

    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.

    Much more below the fold…

  • 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.
    Promising Embryonic Cell News
    Reprogramming Adult Cells into ES cells
    Does Smoking Cannabis Cause Schizophrenia?
    Again with the Marijuana
    Global Warming is a threat to Global Health
    A Critical Appraisal of Chronic Lyme

    Enjoy! And good work Dave, Mike, John and others for getting this idea up and running.

  • The Placebo effect, how significant is it?

    Are placebo’s really effective? So asks Darshak Sanghavi in Slate, citing this study from 2001 that shows the placebo effect, compared to passive observation, to be relatively minor for improvements in pain or objective measures of health.

    This is an interesting topic, but unfortunately, a really bad article. Given how many alties love to stress the role of placebo and its apparent proof of the benefit of positive thinking, we should critically re-evaluate the evidence that placebos on their own can do anything more than improve subjective symptoms. Although there is a fair amount of proof that the placebo effect is a lot less significant than many believe even for those. It would be worth evaluating the effect of placebo itself – if ethically possible – more rigorously for specific symptoms and illnesses.

    It’s an interesting article all the same and, deserves some consideration, but I worry Sanghavi’s analysis is so unsophisticated it damages an otherwise worthy goal. For one, he starts with a pretty egregious genetic fallacy:

  • Denialists should not be debated

    Orac has brought up the interesting point that debating the homeopaths at U. Conn might not be a good idea.

    On a related note, in a post derriding attacks on consensus I was asked by commenters if isn’t it incumbent on science to constantly respond to debate; to never let scientific questions be fully settled. And I understand where they’re coming from. These ideas represent the enlightened ideals of scientific inquiry, free speech, and fundamental fairness.

    However, they’re also hopelessly misplaced in regard to the problem at hand. That is, denialists, cranks, quacks, etc., are not interested in legitimate debate or acting as honest brokers trying to bring clarity to a given issue through discussion. Orac dances around this issue a little bit, talking about the challenges of debates with pseudoscientists because they are hard to pin down, but the fundamental problem, simply put, is the absence of honesty and standards. Academia and science are critically dependent on debate, this is true, but the prerequisite for having the debate is having people who are honestly interested in pursuing the truth and operate using the same rules of evidence and proof. It’s not about censoring dissent, which the cranks insist is the issue in their eternal pursuit of persecution. It’s about having standards for evidence and discussion. This is why these debates, when confined to a courtroom, often fare so disastrously for the denialists. In the presence of standards that exist before evidence can be introduced, they are left with nothing.

    In what is probably the best book on denialist tactics Deborah Lipstadt’s “Denying the Holocaust”, are the best arguments for not engaging in debate with denialists. Now, I realize we’re not talking about scum-of-the-earth holocaust deniers here, but the fact is, the tactics and the methods are ultimately the same no matter how noble or evil the motive. Just because the motives or ideologies of the other cranks or denialists are different, doesn’t mean that they don’t have the exact same flaws in their arguments, use of evidence, or fundamental honesty. Lipstadt explains the risks then of entering into debates with deniers:

  • No Imagination Without Religion? Lee Seigel is an idiot.

    Noted sockpuppet and sniveler Lee Siegel warns us that the new militant atheists may be closing the book on imagination. And for some reason the LA Times saw fit to publish this tripe.

    In the last few years, so many books have rolled off the presses challenging God, belief and religion itself (by Sam Harris, Daniel Dennett, Richard Dawkins, Victor Stenger and Christopher Hitchens, among others) that a visitor from another planet might think America was in the iron throes of priestly repression. You’d never know that we live in the age of Paris Hilton, HBO, Internet porn and flip-flops. The 17th century Catholic Church proscribed Galileo — just imagine what it would have done with the creators of “Entourage.”

    Here we start out poorly. One assumes you have to object to something only when being persecuted by it. Siegel is saying we can’t object to magical thinking unless we’re undergoing an inquisition? And that Paris Hilton is the symbol of our freedom? Atheism = tolerance of trashy whores and nudity on the TV (in the US)?

    …that the separation of church and state is inscribed in our Constitution; that no priest, minister or rabbi holds any top position in the federal government; and that even the state board of education in Kansas recently forbade the teaching of creationism. The Catholic Church imprisoned Galileo and hounded Voltaire and his fellow philosophers; Harris & Co., meanwhile, are dining out on their self-styled iconoclasm in every corner of the media.

    It’s true, atheism, in this country, does not result in imprisonment or persecution. We call this progress. But it’s also ignoring the points made by Dawkins and Hitchens about religion’s influence around the world, real persecution of those that are different in theocratic states, and the quieter discrimination and reviling of science and reason that we must constantly be vigilant of in this country. Siegel then goes on to acknowledge the problems he spends his first paragraphs saying don’t exist, and makes the idiotic argument that books about atheism don’t do any good unless they’re designed to convert opponents.

    Who, exactly, are they aimed at? Who is the ideal reader of these attacks on belief in God? Not Muslim or Christian fundamentalists, obviously, because one of the engines driving religious fundamentalism today is, precisely, a hostility toward modern science. If anyone thinks that Dawkins’ book, “The God Delusion” — with its “scientific” attempts to refute the existence of God — is going to persuade today’s religious fanatics, here or abroad, to loosen up and enjoy a little MTV, you have to ask yourself just who is “deluded.” It’s hard to imagine anyone abandoning his faith after reading Harris’ condescending polemic, or the science of Dawkins and Dennett, or Hitchens’ vitriol.

    I sincerely doubt that the goal of any of these writers is conversion of people like James Dobson or Ted Haggard, and no one realistically thinks that is the objective of the books. There are such things as people without their minds made up, people on the fence, and those that would like to solidify their arguments and understanding of atheist philosophy. Clearly they are selling though, so maybe Siegel should spend less time worrying about their audience.

    The attacks in the books often don’t make much sense either. For instance, Bush and his gang preach Christian values while lying us into a slaughterhouse overseas, ransacking our public coffers and ignoring social inequities and iniquities at home — and so our heroic anti-religionists attack . . . Christian values. But shouldn’t they be attacking Bush and Co.’s hypocrisy in betraying Christian values instead? Such polemics are a case of throwing the sacred bathwater out with the baby. The analytic philosophers used to call such arguments that so sorely miss the mark “category mistakes.”

    Ah yes, we call this argument the “Courtier’s Reply. The problem is clearly not religion, because Dawkins et al., aren’t writing about true religion, you know, people helping out their neighbors and working in soup kitchens. Fanaticism has nothing to do with real religion which is all sweetness and light all the time. As J.J points out, this is a straw man, because the issue isn’t the moral lessons of each religion being obeyed (although as Hitch points out many of these are highly questionable). It’s much harder to defend what Dawkins actually attacks, the improbability of the existence of deities or the supernatural.

    Now so far, all we’ve seen is the usual tripe. But we haven’t really seen how far down Siegel can stoop in his criticism of the new atheists. Prepare to see, quite possibly, the most absurd and offensive arguments yet against the new atheists.

  • Can You Really Strangle Yourself Getting out of Handcuffs?

    I thought for sure the idiotic slugs that pass for security in our airports had mishandled this woman resulting in her death when they said she strangled herself while trying to escape from handcuffs. However, Slate reports indeed you can manage to screw up this maneuver and contort yourself into such a position. They also linked this video

    showing how the double-jointed might attempt this maneuver, while warning people not to try it at home with handcuffs and asphyxiate themselves like this woman did.

    Not that I’m saying this lets the cops entirely off the hook, but I have to admit surprise that it’s possible for some people to bring their hands over their head that way.

  • Welcome A Few Things Ill-Considered!

    It looks like it will be two announcements of new sciblings today. We have A Few Things Ill Considered joining us at Scienceblogs. It’s a climate science/debunking blog I’ve been familiar with for a while, and author of the excellent Howto talk to a climate skeptic.

    Welcome!

  • New Scibling – Sciencewoman

    Welcome Sciencewoman to the block, as she starts up her new blog here. I’m continually impressed with our Sb overlords and their ability to acquire a diverse set of talented individuals. It seems they’re doing a better job the The Scientist as some of my sciblings have pointed out.

  • Genomicron on Genome Size

    For anyone curious about complexity, genome size, and non-coding or “junk” DNA, there are a number of good posts on the topic at Genomicron.

    See in particular Junk DNA: let me say it one more time fand Function, non-function, some function: a brief history of junk DNA for a discussion of what junk DNA is, what it means for biology, and why creationists that have made hay out of it are purposefully misunderstanding and misrepresenting it.

    And What’s wrong with this figure? for a discussion on a common mistake in assuming that genome size automatically means increasingly complex organisms.

    Good stuff, should be required reading, and nice examples of corrections of popular misconceptions about biology.
