Judgment Day Is Coming

 
NOVA has produced a documentary on the Kitzmiller v. Dover Area School District trial that took place two years ago [Judgement Day: Intelligent Design on Trial].

The complete show will be available on the website [Watch Online] after November 14th. In the Toronto area we can watch it on WTVS Detroit (channel 163) on Tuesday Nov. 13th at 8pm or on WCTS Seattle (channel 164) at 11pm our time. Most people probably don't get these channels because they're part of a special timeshifting package. I find that WNED Buffalo, the regular PBS channel in this area, often doesn't show the documentaries I want to watch on PBS. It doesn't broadcast NOVA documentaries, for example. I assume they're too expensive.

Here's the trailer. The show looks really cool even if ultimately the trial will have very little effect on the creationist movement and may even have strengthened it.



Rachel Marsden Fired by the Toronto Sun

 
Rachel Marsden is officially a Canadian although most Canadians would prefer than this not be widely known. She's currently based in New York city. Here's how she describes her upbringing in Vancouver [About Rachel Marsden].
Born in suburban Vancouver, British Columbia, Rachel grew up listening to Jack Webster, who pioneered combative political talk-radio long before it ever spread to the USA.

Fully bilingual in both French and English, Rachel survived growing up in Canada during the socialist regime of Prime Minister Pierre Trudeau, best known for his close friendship with Fidel Castro, decimation of the Canadian military, a wife who partied at Studio 54 with the Rolling Stones, and doing pirouettes behind the Queen of England's back.

Always a capitalist at heart, Rachel spent her childhood on her parents' farm selling eggs from the family driveway. To ensure the operation looked legit and to score an advantage over the competition (the neighborhood Safeway), she would hold her pet chicken, Brenda (named after her Sunday school teacher), on her lap as proof that the eggs were truly "farm fresh".
Here's a clip of Rachel Marsden on CNN from just last week. She's defending the torture of so-called terrorists1—one of her favorite topics—while getting skewered by Jack Cafferty. One of her most famous recent quotes comes from this broadcast, "One man's torture is another man's CIA-sponsored swim lesson."

Marsden used to write a weekly column for the Toronto Sun. one of Canada's most idiotic right-wing rags. This relationship is now over according to her website [RachelMarsden.com].
Attention terrorists and Islamofascists: You can now read the Toronto Sun without having your delicate sensibilities offended, as my weekly column is no longer with Sun Media. I am currently exploring US syndication and other venues for the column. In the meantime, you can continue to read it here at RachelMarsden.com, every Monday. And yes (to respond to some of your queries), after more than 2 years of writing weekly for the Sun, I've been under a new Editor-in-Chief, Lou Clancy, since October 5th, who comes from Canada's most liberal newspaper: The Toronto Star. My column about Islam was spiked on his first day at the job. Best of luck to any principled conservatives who remain.
Now, the remarkable thing about this is that even the Toronto Sun has had enough of Rachel Marsden. Who woulda thunk?

I guess she'll just have to sell her brand of "principled conservatism" south of the border from now on. No doubt she'll find plenty of buyers. I understand that the USA is about to appoint an Attorney General who approves of torture.

Here's an excerpt from her last column in the Toronto Sun [Torture? Sounds like a swimmingly good idea].
When asked about it during a recent CNN appearance, I suggested that "one man's torture is another's CIA-sponsored swim lesson." In case anyone thought I was being facetious -- I wasn't.

I suppose that those who object to terror suspects getting water up the nose would say that, as a young competitive swimmer, I was also tortured. It was called "hypoxic training" -- swimming underwater and holding our breath until we passed out. Our coaches didn't call it torture, just an exercise in "mental toughness." So think of it this way -- terror suspects are getting some free mental toughness training courtesy of the U.S. government.

Here's another idea to make the concept more palatable to objectors: Call the place where waterboarding is performed "The CIA Centre For Aquatic Excellence," give all participants an "I survived training camp" T-shirt with the centre's logo on it, and treat them to a couple of carbo-loading pancake breakfasts. It worked for us.
Judge for yourselves.


1. All of the people who are being tortured are merely "accused" of doing something wrong. Many of them are innocent. Very few of them are real terrorists.

Nobel Laureate: Emil Theodor Kocher

 

The Nobel Prize in Physiology or Medicine 1909.
"for his work on the physiology, pathology and surgery of the thyroid gland"


Emil Theodor Kocher (1841-1917) received the Nobel Prize in Physiology or Medicine for discovering that the thyroid gland was an essential organ. It secreted a component that was required for proper development and daily metabolism. We now know that the secretion consists of two iodine-containing hormones; thyroxine and triiodothyronine [Monday's Molecule #50].

The Presentation Speech was given by Professor the Count K.A.H. Mörner, Rector of the Royal Caroline Institute, on December 10, 1909.
Your Majesty, Your Royal Highnesses, Ladies and Gentlemen.

The Nobel Medical Prize has been awarded this year to the famous surgeon, Professor Theodor Kocher of Bern, in recognition of his work concerning the physiology, pathology and surgery of the thyroid gland.
The thyroid gland, thyroidea, is one of the structures in the organism whose significance has only been made clear during the last few decades. At the close of the 1870's it was still stated in the physiology text-books that the function of this gland was a complete mystery. It was even questioned that it had an actual physiological significance, for the adult organism at least. On the other hand it was a common experience that it could be the site of pathological changes; in the course of these, considerable trouble could result, as, for example, when the pathologically enlarged gland exerted pressure on neighbouring parts, especially on the trachea.

Yet it was hardly right that this gland should have been undervalued, not to say disdained, for so long. Astley Cooper, who was working about a hundred years ago, had already observed disturbances in animals after removal of the thyroid. These were specified with greater precision by J. M. Schiff in Bern. He found that animals in which the thyroid had been extirpated, often died in circumstances which suggested that this gland might be of great importance to the organism; however, he did not gain any deeper insight into the gland's function. Unfortunately, these observations did not receive the necessary attention and development. It was only after similar results had been obtained with human beings that the question of the thyroid's significance was analysed successfully. Observations made by surgeons were the cause of this.

The disturbances which occur with a pathological enlargement of the thyroid are often so grave that people had already for many years been extirpating the thyroid occasionally to relieve them, despite the difficulty and dangers which the operation then presented. Indeed, in the days before the introduction of antisepsis it often happened that the patients died of the immediate results of the operation. After the introduction of antisepsis a significant improvement took place in this respect. As a result, the number of operations of this kind, in which the whole gland was removed, increased considerably. In the meantime it was gradually noticed that the position was by no means satisfactory, even if the operation itself and the subsequent healing had gone well. Not infrequently, after a period of apparent health, significant disturbances in the general health made their appearance. The conscientious investigation of these cases of illness resulted in the establishment of a new syndrome called «cachexia strumipriva», which was characterized by muscular weakness, swelling of the extremities and of the face, anaemia, decline in intelligence, and finally death from exhaustion. Once attention had been drawn to this condition, enthusiastic and productive research into the significance of the thyroid followed in many different centres. In this, reliance was placed on clinical observations on humans as well as on animal experiments. From this research an understanding of the physiology of the thyroid has evolved which is comprehensive, even if not complete in all respects.

We now know that this gland is a vital organ, whose total removal in experimental animals infallibly causes death within the course of a few days or weeks. The gland is of great importance in the general nutrition of the adult, and especially in individuals still undergoing development. The loss of thyroid function results in serious disturbances in this nutrition. Metabolism is significantly diminished; growth ceases; the skin and the subcutaneous tissues are the site of mucous infiltration; degenerative processes occur in internal organs; serious disturbances make their appearance in the functions of the nervous system and muscles. It became clear that the gland acts by elaborating a secretion, which reaches the various parts of the body. It is, as the expression goes, an internal «secretion». Later it became evident that such processes of internal secretion are of exceptionally great importance. Not only the thyroid, but also various other glands such as the adrenals and the pancreas play a characteristic part in the processes within the organism by elaborating a secretion peculiar to each gland, which is not excreted, but is diffused throughout the organism and is of the greatest importance to it.

The knowledge of the physiology of the thyroid has brought a valuable increase in our understanding within the field of pathology. Through it new light has been thrown on hitherto mysterious morbid conditions. Pathological changes in the gland can lead to suppression or decrease of its function. Various morbid conditions are explained by this, among which are cretinism and myxoedema. On the other hand one looks for the explanation of various other disturbances such as those in morbus Basedowi in abnormally increased or possibly qualitatively abnormal activity of this gland.

This briefly outlined important and momentous development, which has benefited medicine during the past 25 years, was brought into being, as I mentioned before, as a result of observations which have been made by surgeons. In this respect, the first public utterance was made in September, 1882, by Professor J. L. Reverdin in Geneva. At this time his colleague in Bern, Professor Kocher, had also turned his attention to the same subject, and in April, 1883, the latter gave a comprehensive exposition, which has been of fundamental importance to the later development of thyroid surgery as well as to other important areas of our knowledge of this gland. Through Kocher's exposition it became quite clear that complete extirpation of the thyroid is reprehensible. A portion of the gland which is capable of functioning, must be left behind at operation. This very important principle of surgical intervention has always been observed from that time onwards. With regard to the surgery of the thyroid, Kocher has subsequently continued to occupy a leading position. It should be possible to omit on this occasion a report concerning the development of the methods of operation and the suitability of the various types of intervention in different cases. It should suffice to recall that there are now several thousand people who owe their regained, lasting health directly to him after a goitre operation which he has successfully performed. A far greater number, which cannot be estimated, owes him a debt of gratitude indirectly for similar results. Fatal cases or secondary illnesses have become more and more of a rarity in goitre operations.

However, it is not only the treatment of the goitre which has been the subject of Kocher's research on the goitre. He has also carried out extensive investigations into the causes of the endemic occurrence of goitre in certain regions and into the cretinism connected with disturbances in thyroid function.

In the thyroid, as already indicated, other diseases can occur in addition to those which arise with the ordinary goitre. To these as well Kocher has devoted successful work, as a result of which it has been possible to define with more and more certainty the method of treatment best suited to each case; in addition, on the basis of Kocher's work a broader, deeper knowledge of the pathology of the thyroid has been achieved.

Through his research, which we have briefly described here, Kocher has carried out pioneering work of an enduring nature which is of the greatest importance to medical science and of the greatest value in the service of suffering humanity. It is this work which the Staff of Professors of the Caroline Institute has wished to honour by awarding him this year the Nobel Prize in Physiology or Medicine.

Fixing a Bad Design

 
Mark Hoofnagle on denialism blog has posted an interesting article on how to fix badly designed humans [Ask A Scienceblogger - Which parts of the human body could you design better?]. I agree with most of his suggestions but he left out some.

Childbirth is definitely a serious problem as Mark points out. It's one of the important proofs of evolution 'cause no intelligent designer would ever come up with the mechanism we have now. Another problem is menopause. Very few people who have lived through it (wives and husbands) think it's a good thing. Let's get rid of it entirely. I doubt very much that we would see a massive increase in fifty-year-old mothers.

I'm not a big fan of our immune system. Sure, it has some good points but a real intelligent designer could do a much better job. It looks like it was designed by Rube Goldberg or some drunken sailer. The only thing it's really good at is generating Immunology Departments and thousands of scientific papers.

Let's fix it so that it doesn't get confused by peanut antigens and other ridiculous things that can kill you. We don't want no more asthma and auto-immune diseases. How hard can it be? There's got to be a more simple way of doing the same job.

A Global Moritorium on the Death Penalty

 
The United Nations Human Rights Commission has voted every year from 1998 to 2005 on a resolution calling for a moratorium on the death penalty. Canada has been a sponsor of this resolution every single time along with countries such as the United Kingdom, France, and Australia and 71 other countries. I'm proud of Canada's leadership on this important issue.

This leadership is about to end according to CTV [Feds won't sponsor UN anti-death-penalty resolution].
OTTAWA -- The Conservative government will not co-sponsor a United Nations resolution calling for a global moratorium on the death penalty, breaking with a nearly decade-old tradition.

An official with the Foreign Affairs Department says Canada will vote in favour of the resolution when it comes to the floor of the UN General Assembly in December, but will not sponsor it.

"There are a sufficient number of co-sponsors already, and we will focus our efforts on co-sponsoring other resolutions within the UN system which are more in need of our support,'' said Catherine Gagnaire.
Yeah, right. This represents a substantial shift in policy for the Canadian government. It's consistent with another change recently announced whereby Canada will no longer oppose the execution of Canadian citizens in foreign countries.
Last week, Public Safety Minister Stockwell Day surprised the House of Commons by announcing that Canada will not oppose the execution of a Canadian citizen on death row in Montana for two murders. Day said the new policy will apply to "murderers'' such as Ronald Allen Smith who have had a fair trial in a democratic country. (Doesn't the idea of Stockwell Day as "Public Safety Minister" just want to make you cry? )

The government has not specified which countries it considers democracies.
One of those countries is surely the United States of America. A country that executes Canadian citizens and has voted against the UN Human Rights resolution every single time.

The UN resolution has never passed thanks to the USA and other nations that still have a death penalty (e.g. Iran, Iraq, Saudi Arabia). Canada abolished the death penalty in 1976 and there haven't been any executions in this country since 1962. Let's hope Stephen Harper doesn't try and bring back the death penalty remove us from the list of enlightened liberal democracies.

The Logic of the IDiots

 
Intelligent Design Creationists are really upset that their views aren't taken seriously by real scientists. They want to claim that Intelligent Design Creationism is science. So far they haven't succeeded but that doesn't stop them from trying again and again.

The latest attempt by DaveScot has just been posted on Uncommon Descent [P. falciparum - No Black Swan Observed]. Let's look at this stunning example of creationist logic.

DaveScot says that scientific statements have to be capable of falsification in order to qualify as science. That's one view of what science is all about (Popperian) but it's not the only one. Nevertheless, let's run with this definition and see where it takes us.

DaveScot gives us an example of a falsifiable statement, "All swans are white." The discovery of a single black swan would falsify that statement. That's correct. Now he goes on to make a statement about intelligent design, "All complex biological systems are generated by intelligent agents."

Hmmm .... that's an interesting statement isn't it? There are no known examples of complex biological systems that have been generated by intelligent agents. From a logical perspective, it's like saying that Pluto is made of green cheese. But, what the heck, let's see where he's going with this.
What we don’t know is whether any non-intelligent means can generate complex biological systems. A single observation of a complex biological system generated by a non-intelligent cause will falsify the biological ID hypothesis.
Now I see the logic. All the evidence for the natural evolution of complex biological systems doesn't count for a damned thing. You have to actually see something like that evolve with your own eyes before you can believe it. If you don't actually witness the thing then it's logical to assume that it doesn't exist. Right?

What's the data? Well, according to DaveScot, scientists have given it their best shot and no complex biological system sprang into being. The experiment was performed with Plasmodium falciparum the protozoan that causes malaria [Plasmodium falciparum Causes Malaria].
P.falciparum replicating billions of trillions of times in the past few decades represents the largest search to date for a “black swan”. This is orders of magnitude more replications than took place in the evolution of reptiles to mammals wherein there are many exceedingly complex biological systems that separate them. If P. falciparum had been seen generating any complex biological systems such as those that distinguish mammals from reptiles then it would have falsified the ID hypothesis. None were observed. This doesn’t prove ID but it certainly lends strong support to it. All perfectly scientific.
Don't you just love creationist logic? Just because we haven't seen any complex biological systems spring naturally into existence in Plasmodium falicparum it follows that it's impossible for such thing to happen. Therefore Intelligent Design Creationism is strongly supported. QED.1.

WARNING!!!

This experiment could be harmful to your brain. Don't try this at home.
Let's try using this logic ourselves. P. falciparum has replicated trillions of times and not once did we see an Intelligent Designer making anything. This scientific observation lends strong support to the idea that Intelligent Designers don't make complex biological systems, right? It means that evolution is correct.

Furthermore, after hundreds of years of observation involving billions of people, we haven't got a single documented case of anyone actually seing God. This doesn't prove the non-existence of God but it certainly lends strong support to it. All perfectly scientific. At least that's what DaveScot would say, I assume.


1. The argument would make some sense if evolution predicted that complex biological systems should evolve in protozoa every few hundred years. Since evolution predicts no such thing then nothing has been demonstrated except that Intelligent Design Creationists are IDiots. But we already knew that.

Monday's Molecule #50

 
Today's molecule may seem very simple but be careful. Pay close attention to the structure before you venture a guess. You need to give as complete a name as possible.

There's an indirect connection between this molecule and Wednesday's Nobel Laureate(s). The Nobel Prize winner(s) didn't know about this particular structure but its effects were detected.

The reward goes to the person who correctly identifies the molecule and the Nobel Laureate(s). Previous winners are ineligible for one month from the time they first collected the prize. There are two ineligible candidates for this week's reward. The prize is a free lunch at the Faculty Club.

Send your guess to Sandwalk (sandwalk(at)bioinfo.med.utoronto.ca) and I'll pick the first email message that correctly identifies the molecule and the Nobel Laureate(s). Correct responses will be posted tomorrow along with the time that the message was received on my server. This way I may select multiple winners if several people get it right. This one is easy. Get your response in quickly.

Comments will be blocked for 24 hours. Comments are now open.

UPDATE: The molecule is triiodothyronine (2-amino-3- [4- (4-hydroxy-3-iodophenoxy)-3,5-diiodophenyl] propanoic
acid). We have a winner.


Mendel's Garden: November Edition

 
The 20th version of Mendel's Garden has just been posted on VWXYNOt? [November Kickabout in Mendel's Garden]. CAE started her blog to satisfy her frustrated inner scientist but now that she's back in academia she continues to post good science articles. She lives in Vancouver, British Columbia (Canada) but we try not to hold that against her.


"Animal Rights" Is a Complicated Issue

 
Ryan Gregory has put up an interesting posting on Genomicron [On speciesism]. He points out that most of the so-called "debate" about animal rights is at the level of 8th graders. Personally, I think he's being generous.

Ryan asks the following questions,
And so I ask, on what basis do you draw the sharp moral line between "humans" and "animals", "human rights" and "animal rights", "us" versus "them"? What rational argument do you bring in defense of speciesism? Perhaps you argue that only humans are capable of suffering, or that our intellectual capabilities are of a different kind from those of other animals. As Dawkins has noted, neither is compatible with what we understand about evolutionary history.
I don't have an answer to these questions even though I've been thinking about them far longer than youngsters like Ryan Gregory.

Swatting mosquitoes does not pose an ethical dilemma for me. Nor does eating beef, chicken, fish and shrimp. On the other hand, I don't fish and I don't hunt. I don't lose sleep over gorillas in a zoo but I do when they are killed in Africa.

There doesn't seem to be an easy answer to why some animals don't matter while others do.

I'd like to go beyond Ryan's question and include plants. What is the justification for caring about some animals and not about the weeds in your garden or the wheat plants that feed you? I don't think there is a rational basis for doing so. This seems to be one of those issues where rationality doesn't work. That makes me very uneasy.

Goodbye Daylight Saving Time

 
Today we stopped using Daylight Saving Time in Canada.

Last Spring I posted an article about time zones [Happy Daylight Saving Time!]. It included the photograph shown here of a strange thing right outside my building on the University of Toronto campus. If you don't know what it is, follow the link.

Note to students at the University of Toronto: This could be on the The University Exit Exam].

Are You Liberal or Conservative?

 
Today we start a new poll of Sandwalk readers. See the sidebar on the left of this posting.

Try and answer according to where you see yourself on the political left-right spectrum without paying too much attention to the labels. The "left wing" category isn't meant to imply radical Marxism; it's meant to encompass the views of most socialists in Europe. "Liberal" doesn't mean that you have to be a member of a "Liberal" (upper-case L) party. It just means somewhat left-of-center.

Similarly, "right-wing' doesn't mean you share the point of view some evil dictator. It means you have more in common with very conservative points of view than with more moderate conservatives.


Happy Birthday Sandwalk!

 
Today is the first anniversary of this blog. My first posting on November 4, 2006 was Welcome to My Sandwalk. Since then there have been 1282 other postings for an average of 3.5 per day (whew!). My original goal was to average one science-related article per day and I think I've come close to that average. The others are just for fun.

I was told when I began that you have to attract hundreds of views per day in order to generate interesting comments and discussions. That seems to be about right. When I started I saw this blog as an experiment and I intended to re-evaluate after six months. When the six months was up I had not met many of my goals so it was a time of soul searching [My Six Months Are Up!]. What happened was I avoided making a decision so I just kept going by default. I'm glad I did. There are now lots of interesting discussions going on in the comments sections.

All of us science bloggers have discovered one important feature of science blogging. You hardly ever get comments about science. If you check those articles where I talked about science, there are almost no comments or discussion. On the other hand, as soon as you mention politics, religion, or racism, there are dozens of readers who want to speak up.

It's a puzzling phenomenon. That's not to say it isn't fun to talk about those non-science issues—it clearly is a lot of fun or we wouldn't be doing it. The puzzling thing is why there aren't more comments about the science.

From time-to-time I asked for photographs of readers who have walked the real sandwalk. I'd like to acknowledge those who sent in pictures.

Cody
The God Delusion
T. Ryan Gregory
PZ Myers
John Wilkins

I hope I haven't forgotten anyone. Send photographs if you're not on the list already.

For those of you who are interested in the numbers, here are the statistics for Sandwalk. What they mean is that Sandwalk is on the verge of making the transition from a low popularity blog to a medium popularity blog. For comparison, Pharyngula gets one million views a month or 20X more than Sandwalk. In terms of the Top100Science Sites Bad Astronomy is 468th, Pharyngula ranks 794th, and Sandwalk is 1006th

Sandwalk has a long, long way to go. I think I'll try for quality instead of quantity!

Here are the top five postings in terms of number of comments: [Arguing Against God] [The Evolution Poll of Sandwalk Readers] [Propaganda Techniques: Shift the Burden of Proof] [Genomics Is Dead! Long Live Systems Biology!] [Dennett on Adaptationism].

Sandwalk readers are a diverse group in terms of geography. Yes, it's true that a majority of readers come from USA addresses, but there's still a large number of you from Europe, Asia, and Australia. There are even a handful of readers from South America and Africa. Oops ... I almost forget—there are Canadian readers as well.

On other issues the Sandwalk readers are less diverse. About 70% of you are atheists and almost all of you accept evolution—even though it may be the wrong version of evolution.

Next month's poll is going to ask about education. I suspect that most readers have been to university. This month the poll will be about your political views, e.g. where you position yourself on the left-right spectrum. I'll be surprised if most readers don't lean to the left.

Anyway, thanks for reading so far. And please, keep those comments coming—that's the most fun part of blogging.

P.S. If you have any suggestions for improving the looks or content of Sandwalk this is your chance to mention them.
