Summer Course on Intelligent Design Creationism
You can sign up for a full week course on Intelligent Design Creationism at the Discovery Institute in Seattle, Washington (USA) [Deadline Nears for Summer Seminars on Intelligent Design]. It runs from July 10 - 18, 2009 and it's free.The course is open to any student ... almost. There are a few small hurdles that have to be jumped in order to qualify.
If anyone wants to attend I'd be happy to write a letter of recommendation.
- A copy of your resume;
- A letter of recommendation from an ID-friendly source;
- A copy of your academic transcript;
- A short (one page) statement of your interest in ID within your field of study.
Christine Hurley - The Flamboyant Psychic
Back in October 2007, I posted a short message about a psychic who was arrested for fraud. I linked to Mike's Weekly Skeptic Rant because he had an interesting multiple choice question [see Psychic Arrested in Calgary].A Calgary psychic named Christine Hurley posted a comment where she claimed to be as interested as the rest of us in weeding out psychic frauds. (Yes, I do see the irony.)
Since then, she has posted several more comments designed to promote her "skills" in psychic reading. You can benefit from her psychic powers by charging $120 to your credit card for a 30 minute phone reading [Christine Hurley: Prices]. An even better bargain is one hour on the phone for $150!
I'm not exactly sure how this works. Presumably Ms. Hurley will tell you all the important things you need to know in the first 30 minutes. Maybe there are some interesting details that require another half hour.
Read the comments and testimonials that are accumulating at Psychic Arrested in Calgary. It's really amazing to see how some people can be completely duped by Christine Hurley into believing that she has psychic powers.
I wonder why she spends so much time collecting $120 (CDN) from her

The Evolution Conspiracy
The Evolution Conspiracy is a book by Lisa Shiel. I'd never heard of her until a few days ago but some of you might know her because she's a fan of bigfoot. She has a masters degree in library science.You can't buy the book until next September but you can read all the rave reviews of this unpublished book on Lisa's website: The Evolution Conspiracy. You can also get an inkling of what the book is about by reading her promotional material. Here's an excerpt ...
Evolution.That's refreshing. Anyone can understand evolution. Anyone, that is, except Lisa Shiel. Her stupidity and ignorance are on display in the comments she's making on science blogs and on her own website. By her own admission she is dropping comments on all the evolution blogs in order to promote her book [Banned by Evolutionists! Can You Handle It?].
One word, deceptive in its simplicity, has transformed the way we look at ourselves and everything around us. Once thought of as unique, man has become one of the animals with no special claim on the planet. As children, few of us question what we learn in biology class about the origins of life and the position man holds in the hierarchy. Science textbooks present evolution as fact—indisputable, inevitable, and incomprehensible to everyone outside the exalted few with PhDs in the appropriate fields.
That’s why this book promotes one key premise—anyone can understand evolution.
The purpose of this posting is to help give her as much publicity as possible in order to expose her as just another kook who has no idea what evolution is all about.
Here's an example from a posting she made on April 7th: You Can’t Tell a Species by Its Cover.The theory of evolution involves numerous complicated and confounding strands—almost as many strands, I dare say, as DNA itself. Charles Darwin posited that natural selection drives the evolution of species, and this idea has become the cornerstone of evolutionary theory. In natural selection, traits that seem beneficial are preserved in a species while undesirable traits gradually disappear. Because natural selection cannot account for all adaptations, scientists devised the theory of genetic drift, in which changes occur at random.Makes you wonder if Lisa Shiel has even read her own book—a book that presumably explains evolution correctly. There are so many factual and conceptual errors in this short posting that it catapults Lisa into contention for the most ignorant IDiot award. And that's saying a lot 'cause the competition is fierce.
Yet no one has ever reproduced the creation of a species via either natural selection or genetic drift; in fact, no one has ever demonstrated scientifically that one species evolves into another. If a theory must adhere to the scientific method to remain a scientific theory, then evolution has failed the test. The scientific method requires repeated testing, and the ability to reproduce results.
Now toss into this mess the recent discovery that some species “evolve” genetically while remaining unchanged anatomically. Scientists at Massey University in New Zealand have found that a reptile called the tuatara differs genetically from its 8,000-year-old ancestors, while retaining the same anatomical makeup and outward appearance. The tuatara’s DNA changes make it the Speedy Gonzales of genetic evolution. According to Axel Meyer of Germany’s University of Konstanz, the discovery suggests “a real disconnect” can exist between genetic and anatomical evolution.
Finally, consider the recent discovery that cryptic species can fool us too—two creatures look identical, but their DNA identifies them as different species. Perhaps the fossilized tuatara aren’t really tuatara after all…
Evolution: The unscientific scientific theory.
Anyway, the bottom line is that there's nothing to see here folks. You can move along to other books and other blogs. Lisa even makes Denyse O'Leary look good.

Nobel Laureate: Max Theiler
The Nobel Prize in Physiology or Medicine 1951
"for his discoveries concerning yellow fever and how to combat it"
Max Theiler (1899 - 1972) won the Noble Prize in 1951 for his work on combating yellow fever.Theiler's most important contribution was the discovery of a variant of the yellow fever virus that did not cause the disease in humans. When injected into healthy patients, this variant produced immunity to the normal disease-producing virus.
This discovery was not immediately useful since attenuated virus from mice was more effective in producing immunity—a result also discovered by Theiler. The Nobel Committee felt that Theiler had made a significant contribution to understanding viral diseases.
One gets the impression from reading the presentation speech that Theiler was also being recognized as a representative of work done by the Rockefeller Foundation.
THEME:
Nobel Laureates
The significance of Max Theiler's discovery must be considered to be very great from the practical point of view, as effective protection against yellow fever is one condition for the development of the tropical regions - an important problem in an overpopulated world. Dr. Theiler's discovery does not imply anything fundamentally new, for the idea of inoculation against a disease by the use of a variant of the etiologic agent which, though harmless, produces immunity, is more than 150 years old. Jenner used a natural virus variant, cowpox virus, against smallpox, and Pasteur produced a similar variant of the rabies virus by repeated passage through animals. So far there have been only a few successful attempts to master a disease by such measures, but Dr. Theiler's discovery gives new hope that in this manner we shall succeed in mastering other virus diseases, many of which have a devastating, effect and against which we are still entirely powerless. Max Theiler, therefore, has rendered mankind such a service as Nobel made a condition for the awarding of this prize.
Dr. Theiler. For a period of almost forty years the International Health Division of the Rockefeller Foundation has carried on very comprehensive and fruitful work in combating yellow fever and extending our knowledge of it. Among the many who have made their contributions, you take an especially prominent place, because you have made their contributions profitable and because you have opened the way to greater understanding of the epidemiology of the disease and to an effective prophylaxis against it. The Caroline Institute esteems your research work so highly, not the least for its practical value, that it has found it proper to award this year's Nobel Prize in Physiology or Medicine to you.
I ask you, Dr. Theiler, to receive the prize from the hands of His Majesty, our gracious King.

Gary Goodyear's Letter to Nature
Canadian government reaffirms support for science and discoverySirIsn't it strange that basic science researchers are upset about the fact that funding to the major granting councils has been cut for the next three years?
You report researchers' concerns about the Canadian government's support for science in two recent News stories (Nature 457, 646; 2009 and Nature 458, 393; 2009). As Minister of State for Science and Technology, I can say that, despite the global economic situation, the government of Canada remains committed to innovation and discovery. We have increased funding to researchers, both in universities and in the private sector.
In the past three years, for example, we have significantly increased the budgets of federal granting councils, increased scholarships through the Canada Graduate Scholarships Program, and increased the Industrial Research Assistance Program for small and medium-sized businesses. The Budget 2009 announcements include Can$750 million (US$590 million) for the Canada Foundation for Innovation to attract and retain world-leading researchers, and a Can$2-billion infrastructure programme. The government has also put in place two five-year funding agreements with Genome Canada that are worth Can$240 million, to support large-scale, world-class research.
Your readers should therefore rest assured that the government of Canada will continue to fund research for the benefit of all scientists and Canadians.
Either the researchers are correct, and Canadian basic research is in trouble, or Gary Goodyear is correct and the Conservatives are doing a fine job.
I know who is telling the truth.
Do Science and Religion Conflict in Louisiana?
The National Center for Science Education reports on the results from a recent poll in Louisiana [Polling Evolution in Louisiana]. Respondents were asked the following question.
Do you think the scientific theory of evolution is well supported by evidence and widely accepted within the scientific community, or that it is not well supported by evidence and many scientists have serious doubts about it?39% answered "yes" and 21% didn't know. 40% said that evolution is not well supported by evidence and/or is not accepted by the scientific community.
Let's dismiss the 21% who didn't know the answer. That leaves almost 80% of the population who see no conflict between science and religion. Half of them probably believe in a God who accepts evolution and the other half of them think that the scientists reject evolution, which maked science compatible with creationism.
That's pretty amazing, and scary, when you think about it.

Teabagging
Today is April 15th. It's a significant day in America because income taxes are due. It's also the day when some people are protesting taxes by having "teabagging" parties. If you don't live in the USA, or watch American television, you've probably never heard of "teabagging." Here's a quick summary from a show that I watched on MSNBC.
Listen for Lawrence O'Donnell, who explains the importance of socialism in America. According to O'Donnell, America is like all other Western industrialized nations. It has a mixed economy (capitalism and socialism).
I agree with that. I don't agree with his claim that, compared to all other nations, American probably has the best mix of socialism and capitalism.
Monday's Molecule #117: Winners
UPDATE: The molecule is yellow fever virus.
The Nobel Laureate is Max Theiler.
This week's winner is Maria Altshuler of the University of Toronto.
Today's "molecule" is fairly complex for a "molecule" but not quite as complex as a living cell. You have to identify the particular type of "molecule" that's shown here but it will be too hard to do that without some clues. One of the clues is the connection to a Nobel Laureate. The other one is cleverly hidden in the bottom part of this posting.The first person to identify the "molecule" and the Nobel Laureate wins a free lunch at the Faculty Club. Previous winners are ineligible for one month from the time they first won the prize.
There are seven ineligible candidates for this week's reward: Dima Klenchin from the university of Wisconsin, Alex Ling from the University of Toronto, Bill Chaney of the University of Nebraska, Elvis Cela from the University of Toronto, Peter Horwich from Dalhousie University, Devin Trudeau from the University of Toronto, and Shumona De of Dalhousie UniversityDima and Bill have donated their free lunch to a deserving undergraduate so I'm going to continue to award an additional free lunch to the first undergraduate student who can accept it. Please indicate in your email message whether you are an undergraduate and whether you can make it for lunch.

Child Abuse and the Anti-Vaccination Movement
I was attending the Center for Inquiry 12th World Congress in Washington last weekend and I happened to catch a re-broadcast of a Larry King show on the "dangers" of vaccinating children. It was an appropriate reminder of the lack of rationalism in our society.
Normally I'm fairly tolerant of people who reject standard medicine. In fact, society might actually benefit when these stupid people are eliminated by succumbing to various diseases. That's what the Darwin awards are for.
But this case is different. These adults are not putting themselves at risk—they are endangering their children.If you stop vaccinating your children you are putting them at risk for many deadly diseases. Some of your children will die. If everyone stops vaccinating children then millions of children will die. How can anyone in their right mind think that vaccinations are so dangerous that the risk is worth it?
I'm not surprised that movie actors and average citizens are kooks. I am surprised that normally responsible TV networks like CNN contribute to potential child abuse. But I'm absolutely shocked that there are physicians who go along with the kooks.
One of those physicians is Dr. Bernadine Healy who appears in this CNN clip. I was astonished to hear her advocate more studies, lending credibility to the claims that vaccinations cause autism and other diseases. Bernadine Healy is a Republican who was the head of the National Institutes of Health under George H.W. Bush. She was removed when Clinton took over the Presidency in 1993.
Healy's defense of the anti-vaccination movement did not ring true. Her "statistics" didn't sound reasonable to me but I was in no position to refute them directly. Fortunately Orac has taken up the task at Bernadine Healy: Flirting with the anti-vaccine movement. Thanks Orac.
You know we're in trouble when the media and former NIH directors can't tell the difference between science and superstition.
This reminds me of the debate over the fluoridation of water back in the 1950's. There were kooks who warned us that fluoridation was dangerous and that it was a communist plot.
Dying for Love in Afghanistan
It's been eight years since coalition forces "liberated" Afghanistan. Here's the result: Taleban 'kill love affair couple'.Mr Azad said: "An unmarried young boy and an unmarried girl who loved each other and wanted to get married had eloped because their families would not approve the marriage."The people of Afghanistan should make up their own minds about whether this sort of behavior is tolerable. We cannot do it for them. As long as the country is semi-united in repulsing foreign invaders it will put off the social reforms that could bring it into the 21st century.
Officials said the couple were traced by militants after they tried to go to Iran. They were made to return to their village in Khash Rod district. [Nimroz province, south-west Afghanistan - see map]
"Three Taleban mullahs brought them to the local mosque and they passed a fatwa (religious decree) that they must be killed. They were shot and killed in front of the mosque in public," the governor said. ...
Extrajudicial "honour killings" have been widely carried out in Afghanistan since then by conservative families angered by a relative who has brought them shame - usually by refusing to marry a chosen partner.
The Taleban have widened their influence over the past three years and now control many remote districts where there are not enough coalition forces to establish a permanent presence.
It's time to leave and let them face up to, and solve, their own internal problems. No people in the world would tolerate a foreign army from a different culture coming in and telling them how to behave—even if they suspected that their behavior was immoral.
Imagine that the USA was invaded and conquered by a European army who insisted that gays be allowed to marry, socialized medicine is begun, the metric system is imposed, proportional representation becomes the law, and capital punishment is abolished. Would those changes be welcomed by Americans who all of a sudden recognize that the foreigners are correct? Or would the changes be resisted even more fiercely because advocating change means siding with the enemy?

Wild chimpanzees exchange meat for sex
I don't know if it's true that Wild chimpanzees exchange meat for sex but I know some vegetarians who may find it interesting.Wild female chimpanzees copulate more frequently with males who share meat with them over long periods of time, according to a study led by researchers from the Max Planck Institute for Evolutionary Anthropology in Germany, published in the open-access, peer-reviewed journal PLoS ONE April 8.It probably works for humans as well.
I'm going out to buy some steaks for dinner.
The original paper is Gomes and Boesch (2009)
Gomes, C.M. and Boesch, C. (2009) Wild Chimpanzees Exchange Meat for Sex on a Long-Term Basis. PLoS ONE 4(4): e5116. DOI:10.1371/journal.pone.0005116
Which Gas Is Cheapest?
Here's three photographs of gas station signs. The one on the left was taken in Mississauga, Ontario, Canada and the two on the right were taken in Bethesda, Maryland, USA. The Bethesda gas stations are one block apart.
Assuming that the photos were taken on the same day (Wednesday, April 8, 2009), which station has the cheapest gas if you pay by credit card?
A Breakthrough in Gene Expression?
When we teach protein synthesis in undergraduate molecule biology classes we cover the main mechanisms regulating the rate of translation. One of them is the influence of codon bias among synonymous codons. We've known for 35 years that rare codons are translated more slowly that the common codons. Highly expressed genes have a pronounced codon bias in favor of the most common codons. As a result of this phenomenon, it is not true that every codon for leucine, for example, is equal. Some are better than others in some genes. Synonymous codons are not always neutral in their effect. (For a complete description of this phenomenon see: Silent Mutations and Neutral Theory.)
We also teach about the influence of messenger RNA secondary stucture. The classic examples in the E. coli ribosomal protein genes are in all the textbooks, as are the examples of attentuation—especially in the Trp operon. Again, this stuff was standard fair in textbooks and courses beginning in the 1970's.
A press release caught my eye: Penn biologists discover how 'silent' mutations influence protein production. "Cool," I thought, "maybe this is something that I'll have to put into the next edition of my textbook."
Here's the breakthrough.
For biologists, these results fundamentally change the understanding of the role of synonymous mutations, which were previously considered evolutionarily neutral. ....Imagine that. They've rediscovered what most of my students have been taught for 35 years!
The silent mutations changed the amount of fluorescent protein by as much as 250-fold, without changing the properties of the protein. Codon bias, the probability that one codon of three adjacent nucleotides will code for one amino acid over another, was previously thought to be the cause for protein expression variance, but it did not correlate with gene expression in these experiments.
"At first we were stumped," Plotkin said. "How were the silent mutations influencing protein levels? Eventually, we looked at mRNA structure and discovered that this was the underlying mechanism."
[Image Credit: The figure is from page 706 of my textbook. Similar figures are in all biochemistry and molecular biology textbooks. The figure shows the secondary mRNA structure around the initiation codon of the S7 ribosomal protein gene in E. coli. The secondary structure inhibits translation initiation. Although in this case the actual codons are not involved in the formation of double-stranded regions, in other cases they are.]
