Breasts, Genitals and Profanity in the Service of Skepticism

It's time for another report from TAM6, coming to you from sunny downtown Las Vegas, where it got up to 107° F (41.7 ° C) today.

Highlights from today:

Ben Goldacre, M.D. is a British physician and journalist, and author of The Guardian's weekly Bad Science column. He spoke today about homeopathy in the U.K. He pointed out that in 1846, John Forbes, the Queen's own physician, was a strong opponent of homeopathy. He contrasted that to today, where the Queen's personal physician is a homeopath. Only partially tongue-in-cheek, Dr. Goldacre wondered if this movement toward wacky medicine correlated with the loss of the British Empire.

Richard Saunders gave a short summary of skeptical matters in Australia. The best part of his session was an audience-participation experiment of dousing. This elegant experiment was designed to help teach critical thinking to school children. With 5 plastic buckets, a bottle of water, a simple dousing rod, and about 15 minutes, he showed how elementary school kids can grasp and even derive for themselves the principles of randomization, and single and double blinding of an experiment. The next time one of my residents seems a bit hazy on these concepts, I'll bring out the dousing gear.

Penn and Teller hosted a short but zesty Q & A session about their Bullshit! TV series, politics and skepticism. As a longtime fan of their stage act, it was a great treat for me to hear Teller actually speak, which he does quite eloquently, by the way. My favorite Teller quote today:

Q. What skeptical accomplishment are you most proud of?
A. Bringing bare breasts, genitals and profanity to the service of skepticism.

My favorite Penn Jillette quote today:

Q. On your Bullshit! show, are you trying to be fair and unbiased?
A. No. We are trying to be fair and extremely biased.

Alexander Jason told us about some of his exploits as a crime scene analyst, and pointed out how helpful a critical mind was in his line of work. He also described his work with James Randi in the 1980's to help debunk fake faith healer Peter Popoff. The video clip below summarizes some of the events of this scandal.



George Hrab, singer, songwriter, and author extraordinaire entertained us with a number of his creations. My favorite Hrab line, when he had some early sound problems with his guitar: "It's a PC guitar." To a Mac user, 'nuff said.

Dr. PZ Myers, biologist and author of the excellent Pharyngula blog, did not actually disembowel a Christian on stage, as was earlier predicted by some. Instead he gave a nice discussion of the evolution of bat wings. He wrapped up his presentation with a slide of "gratuitous squid porn". It is noteworthy that his presentation is the only one so far in which video clips have worked flawlessly. As you might expect, he uses a Mac.

Dr. Neil deGrasse Tyson, astrophysicist, chairman of the Planetary Society and PBS Nova scienceNow host, gave a truly spectacular keynote address, which he called "Brain Droppings".


These "droppings" covered a wide variety of topics, all built around the central theme of the close relationship between the scientific literacy of a population and the intellectual and creative health of their nation. Tyson gave a vivid account of the role of rising religious fundamentalism in the fall of the Islamic intellectual empire around 1100 CE -- a disaster from which the Islamic scientific community has never recovered. Parallels drawn by Dr. Tyson between this disaster and the current U.S. decline in scientific literacy were quite chilling. One hopes that the next administration can begin to repair some of the great damage done in the last 8 years to U.S. scientific research by the current administration.

A brief list of some of the questions considered in this 90-minute talk:

• would an iPhone user have been burned at the stake 10 years ago (maybe so)
  
• is there life on other planets (almost certainly)
  
• does swami levitation work (yes, but only with sufficient flatus)
  
• should we put pictures of scientists on our money (yes, and equations too!)
  
• can lunar tidal forces affect your brain (yes, but they are a trillion times less than those exerted by your pillow)
  
• is breathing, eating and drinking through the same orifice evidence of intelligent design (duh, no -- this is a stupid design that actually kills people)
  

Note to self: Never, ever, ever speak after this man. I'm pretty sure that everyone on the program following Dr. Tyson was thinking the same thing. Neil deGrasse Tyson combines a keen intellect and a strong background in science and history with the passionate lecture style of an evangelical preacher. He makes a powerful advocate for science and its essential role in society. One can only hope that we begin to elect politicians worthy of such an advocate.

Didgeridoo playing could improve sleep apnea

Offhand, I can't think of any connection between the didgeridoo and the practice of radiology.

I don't care.

This clinical trial by Puhan et al was conducted in Switzerland, far from this ancient instrument's origin in Australia. Somehow the authors were able to convince 25 Swiss patients with sleep apnea to play the didgeridoo. Fourteen of these 25 played the instrument for 4 months, while the 11 controls were placed on a waiting list. The bottom line:

Regular playing of a didgeridoo reduces daytime sleepiness and snoring in people with moderate obstructive sleep apnoea syndrome and also improves the sleep quality of partners

Severity of disease, expressed by the apnoea-hypopnoea index, is also substantially reduced after four months of didgeridoo playing

As a radiologist, I spend most of my work days up to my clavicles in high-tech equipment. I therefore relish all the more avocations, such as folk music and hiking, that I can enjoy with low tech gear far from the power grid. Therefore, it's a pleasing thought that a $94 plastic didgeridoo might replace a $1500 CPAP machine in some patients.


On another note, perhaps Switzerland is not such an unlikely place for this particular clinical trial at all. If anything, people who have already been playing alphorns for the past 1,800 years should be naturals at the didgeridoo.
