The Pharyngula Mutating Genre Meme

I confess, I like this blog meme. I studied how mutations happen in bacteria in graduate school, so anything even tangentially related to that has my interest. This blog meme was created by Pharyngula as a means of demonstrating evolution and mutation in cyberspace:

There are a set of questions below that are all of the form, "The best [subgenre] [medium] in [genre] is...". Copy the questions, and before answering them, you may modify them in a limited way, carrying out no more than two of these operations:

* You can leave them exactly as is.

* You can delete any one question.

* You can mutate either the genre, medium, or subgenre of any one question. For instance, you could change "The best time travel novel in SF/Fantasy is..." to "The best time travel novel in Westerns is...", or "The best time travel movie in SF/Fantasy is...", or "The best romance novel in SF/Fantasy is...".

* You can add a completely new question of your choice to the end of the list, as long as it is still in the form "The best [subgenre] [medium] in [genre] is...".

* You must have at least one question in your set, or you've gone extinct, and you must be able to answer it yourself, or you're not viable.

Then answer your possibly mutant set of questions. Please do include a link back to the blog you got them from, to simplify tracing the ancestry, and include these instructions.

Finally, pass it along to any number of your fellow bloggers. Remember, though, your success as a Darwinian replicator is going to be measured by the propagation of your variants, which is going to be a function of both the interest your well-honed questions generate and the number of successful attempts at reproducing them.

The Obesity Epidemic

MarkH, over at Denialism, posted an excellent article about obesity, related health risks, and issues that obscure the problem of obesity. Rather than pull out the best parts, I'm merely going to plug the entire article. Go read it, and the comments. The whole thread is a good read, raising important issues not only about the health risks of obesity, but the cultural and psychological issues that go along with it, and how few options we currently have for taking care of the problem. It's a great discussion. Head on over there.

I was really hoping to have a photo from the Japanese mission to the moon for today, but there aren't any good ones ready yet (just shots of the satellite unpacking itself with the moon in the background). Instead, I provide a photo of "The Whale and The Hockey Stick" from the Astronomy Photo of the Day. If you've never checked them out, you should. Their description of the photo above is:

Explanation: NGC 4631 is a big beautiful spiral galaxy seen edge-on (top right) only 25 million light-years away towards the small northern constellation Canes Venatici. This galaxy's slightly distorted wedge shape suggests to some a cosmic herring and to others the popular moniker of The Whale Galaxy. Either way, it is similar in size to our own Milky Way. In this gorgeous color image, the Whale's dark interstellar dust clouds, yellowish core, and young blue star clusters are easy to spot. A companion galaxy, the small elliptical NGC 4627, appears above the Whale Galaxy. At the lower left is another distorted galaxy, the hockey stick-shaped NGC 4656. The distortions and mingling trails of gas detected at other wavelengths suggest that all three galaxies have had close encounters with each other in their past. The Whale Galaxy is also known to have spouted a halo of hot gas glowing in x-rays.

Homeopathy, malaria & free speech


Orac brings us news of a fellow skeptical blogger, Le Canard Noir, who has been threatened with a lawsuit (in the U.K.) for posting the following article. In honor of free speech, we re-print the article here. Please spread it around, would you?



The Gentle Art of Homeopathic Killing

Thursday, August 16, 2007
The Society of Homeopaths (SoH) are a shambles and a bad joke. It is now over a year since Sense about Science, Simon Singh and the BBC Newsnight programme exposed how it is common practice for high street homeopaths to tell customers that their magic pills can prevent malaria. The Society of Homeopaths have done diddly-squat to stamp out this dangerous practice apart from issue a few ambiguously weasel-worded press statements.

The SoH has a code of practice, but my feeling is that this is just a smokescreen and is widely flouted and that the Society do not care about this. If this is true, then the code of practice is nothing more than a thin veneer used to give authority and credibility to its deluded members. It does nothing more than fool the public into thinking they are dealing with a regulated professional.

As a quick test, I picked a random homeopath with a web site from the SoH register to see if they flouted a couple of important rules:

48 • Advertising shall not contain claims of superiority.
• No advertising may be used which expressly or implicitly claims to cure named diseases.

72 To avoid making claims (whether explicit or implied; orally or in writing) implying cure of any named disease.
The homeopath I picked on is called Julia Wilson and runs a practice from the Leicestershire town of Market Harborough. What I found rather shocked and angered me.

Straight away, we find that Julia M Wilson LCHE, RSHom specialises in asthma and works at a clinic that says,
Many illnesses and disease can be successfully treated using homeopathy, including arthritis, asthma, digestive disorders, emotional and behavioural difficulties, headaches, infertility, skin and sleep problems.
Well, there are a number of named diseases there to start off. She also gives a leaflet that advertises her asthma clinic. The advertising leaflet says,

Conventional medicine is at a loss when it comes to understanding the origin of allergies. ... The best that medical research can do is try to keep the symptoms under control. Homeopathy is different, it seeks to address the triggers for asthma and eczema. It is a safe, drug free approach that helps alleviate the flaring of skin and tightening of lungs...

Now, despite the usual homeopathic contradiction of claiming to treat causes not symptoms and then in the next breath saying it can alleviate symptoms, the advert is clearly in breach of the above rule 47 on advertising as it implicitly claims superiority over real medicine and names a disease.

Asthma is estimated to be responsible for 1,500 deaths and 74,000 emergency hospital admissions in the UK each year. It is not a trivial illness that sugar pills ought to be anywhere near. The Cochrane Review says the following about the evidence for asthma and homeopathy,
The review of trials found that the type of homeopathy varied between the studies, that the study designs used in the trials were varied and that no strong evidence existed that usual forms of homeopathy for asthma are effective.
This is not a surprise given that homeopathy is just a ritualised placebo. Hopefully, most parents attending this clinic will have the good sense to go to a real accident and emergency unit in the event of a severe attack and consult their GP about real management of the illness. I would hope that Julia does little harm here.

However, a little more research on her site reveals much more serious concerns. She says on her site that 'she worked in Kenya teaching homeopathy at a college in Nairobi and supporting graduates to set up their own clinics'. Now, we have seen what homeopaths do in Kenya before. It is not treating a little stress and the odd headache. Free from strong UK legislation, these missionary homeopaths make the boldest claims about the deadliest diseases.

A bit of web research shows where Julia was working (picture above). The Abha Light Foundation is a registered NGO in Kenya. It takes mobile homeopathy clinics through the slums of Nairobi and surrounding villages. Its stated aim is to,
introduce Homeopathy and natural medicines as a method of managing HIV/AIDS, TB and malaria in Kenya.
I must admit, I had to pause for breath after reading that. The clinic sells its own homeopathic remedies for 'treating' various lethal diseases. Its MalariaX potion,
is a homeopathic preparation for prevention of malaria and treatment of malaria. Suitable for children. For prevention. Only 1 pill each week before entering, during and after leaving malaria risk areas. For treatment. Take 1 pill every 1-3 hours during a malaria attack.
This is nothing short of being totally outrageous. It is a murderous delusion. David Colquhoun has been writing about this wicked scam recently and it is well worth following his blog on the issue.

Let's remind ourselves what one of the most senior and respected homeopaths in the UK, Dr Peter Fisher of the London Homeopathic Hospital, has to say on this matter.
there is absolutely no reason to think that homeopathy works to prevent malaria and you won't find that in any textbook or journal of homeopathy so people will get malaria, people may even die of malaria if they follow this advice.
Malaria is a huge killer in Kenya. It is the biggest killer of children under five. The problem is so huge that the reintroduction of DDT is considered as a proven way of reducing deaths. Magic sugar pills and water drops will do nothing. Many of the poorest in Kenya cannot afford real anti-malaria medicine, but offering them insane nonsense as a substitute will not help anyone.

Ironically, the WHO has issued a press release today on cheap ways of reducing child and adult mortality due to malaria. Their trials, conducted in Kenya, of using cheap mosquito nets soaked in insecticide have reduced child deaths by 44% over two years. It says that issuing these nets be the 'immediate priority' to governments with a malaria problem. No mention of homeopathy. These results were arrived at by careful trials and observation. Science. We now know that nets work. A lifesaving net costs $5. A bottle of useless homeopathic crap costs $4.50. Both are large amounts for a poor Kenyan, but is their life really worth the 50c saving?

I am sure we are going to hear the usual homeopath bleat that this is just a campaign by Big Pharma to discredit unpatentable homeopathic remedies. Are we to add to the conspiracy Big Net manufacturers too?

It amazes me that to add to all the list of ills and injustices that our rich nations impose on the poor of the world, we have to add the widespread export of our bourgeois and lethal healing fantasies. To make a strong point: if we can introduce laws that allow the arrest of sex tourists on their return to the UK, can we not charge people who travel to Africa to indulge their dangerous healing delusions?

At the very least, we could expect the Society of Homeopaths to try to stamp out this wicked practice? Could we?

Today's photo comes is taken of rat axons that have been stretched slowly using mechanical forces. A group at the University of Pennsylvania grew their cells in culture, and slowly pulled them apart to demonstrate that it was possible to stretch axons over fairly long distances. From their abstract:

Large animals can undergo enormous growth during development, suggesting that axons in nerves and white matter tracts rapidly expand as well. Because integrated axons have no growth cones to extend from, it has been postulated that mechanical forces may stimulate axon elongation matching the growth of the animal. However, this distinct form of rapid and sustained growth of integrated axons has never been demonstrated. Here, we used a microstepper motor system to evaluate the effects of escalating rates of stretch on integrated axon tracts over days to weeks in culture. We found that axon tracts could be stretch grown at rates of 8 mm/d and reach lengths of 10 cm without disconnection.
