What Kind of People Take Vitamins?

"There's a sucker born every minute."

David Hannum
(frequently attributed to P.T. Barnum)
For normal healthy people there's no evidence that vitamin supplements are necessary, or helpful, in any way [Good Food, Bad Food]. Megadoses of vitamins may be harmful [A bad week for the nutritional supplements industry].

So, why would anyone fork out good money for vitamin supplements?

Biochemistry instructors should make sure students understand the difference between science and pseudoscience. That's why I inserted boxes like this one in the latest version of my textbook.
Whatever happened to vitamin B4 and vitamin B8? They are never listed in the textbooks but you’ll often find them sold in stores that cater to the demand for supplements that might make you feel better and live longer.

Vitamin B4 was adenine, the base found in DNA and RNA.We now know that it’s not a vitamin. All species, including humans, can make copious quantities of adenine whenever it’s needed (Sections 18.1 and 18.2). Vitamin B8 was inositol, a precursor of several important lipids (Figure 8.16 and Section 9.12C). It’s no longer considered a vitamin.

If you know anyone who is paying money for vitamin B4 and B8 supplements then here’s your chance to be helpful. Tell them why they’re wasting their money.

The 10,000 Mile Diet

This article, Shop locally, eat globally? , appeared in today's edition of our university bulletin. I thought it was worth posting a link because, unfortunately, many of my relatives, friends, and colleagues think you can support a large city by only eating food grown within one hundred miles (161 kilometers).
Pierre Desrochers knows how to serve up controversy. When an acquaintance mentions she follows a 100-mile diet to help the environment, Desrochers calmly asks how much energy it takes to heat an Ontario greenhouse.

When a colleague lauds local food as more nutritious than products shipped thousands of miles, Desrochers politely points out that the diet of a 19th-century German peasant consisted of lentils and peas.

Now, the University of Toronto Mississauga geography professor has published a controversial new book that goes beyond polite mealtime conversation and pits what Desrochers calls the “romanticism” of local eating, or locavorism, against the realities of a global food-supply chain.

Desrochers is the co-author of The Locavore’s Dilemma: In Praise of the 10,000-mile Diet, in which he argues that we should stop obsessing about how many miles our food has travelled to get to our dinner plate.

“Three centuries ago most people were eating local food,” Desrochers says. “Why do we think the world moved away from that? There are significant benefits—particularly, environmental and economical—in collaborating to produce food in the best geographic locations.”

Richard Harter 1935 - 2012

I just heard from Dave Greig that Richard Harter died over a month ago [Richard Harter 1935 - 2012]. He was a long time contributor to talk.origins having been there since it was called net.origins in the early 1980s. Richard was a staunch defender of science and evolution and a vocal opponent of stupidity (aka creationism). Here's how he describes the phenomenon that is talk.origns [Evolution, Creationism, and Crackpots].
I discovered the usenet news groups circa 1983. In those days there was no big 8 hierarchy; everything was net.this and net.that. One of the hot groups was net.origins, now talk.origins, the designated dumping grounds for creationism/evolution flame fests.

Some usenet newsgroups are models of decorum, where specialists in sundry topics urbanely discuss their specialties. Some are havens of nattering wherein recipes and small talk are exchanged. Such newsgroups represent usenet at its best as a civilized expression of the electronic personal free press. How boring.

There are newsgroups which are open cockpits wherein all and sundry engage in electonic eye-gouging, leaving bodies scattered about the floor, bodies which miraculously arise to gouge and rabbit punch in return. Much more entertaining. Unfortunately such entertainments pall after a while. The same things are said by the same people endlessly. When one flamer departs he or she is replaced by a clone, another mindless dweeb screaming invective into the electronic night air. There is no content, merely an exchange of prejudices and emotion.

The talk.origins group is, to my taste, a happy combination of meat and sauce. To be sure there are no end of flames. However there is much content also. It all has to do with the subject matter. Talk.origins is supposed to be the arena where creationism and evolution are debated. That happens. However it is a happy hunting grounds for cranks and crackpots who come to be told that they are idiots. They revel in it for, finally, someone is listening to them.

The nifty thing about talk.origins is that you can get a real education by reading the group -- the crackpots are not only told that they are idiots, people cite chapter and verse to show where they are in error. Biologists, archaeologists, paleontologists, and the like post there. There is also a good deal of offbeat humor. For your delectation I have prepared a potpourri of essays and materials drawn from talk.origins.

Richard was born in South Dakota and he moved back there in 2000. He never stopped reminding us that South Dakota actually exists and people actually live there. He died of complications from myelodysplastic syndrome (MDS) [Why couldn't I have something simple, like pneumonia].

There's lots more where that came from. Check out Richard Harter's World while it's still active. I especially like his detailed analysis of one of the most difficult problems in all of science: The Seat Stays Up. His summary of everything related to Piltdown Man is a classic.1

The motto on his web page is appropriate ...
I don't worry about dying.
It's not going to happen in my lifetime.

UPDATE: talk.origins remembers Richard Harter

UPDATE: I'm told that Richard's website will be preserved at Richard Harter's World.

Visiting John Hawks

I'm in Madison Wisconsin. What in the world does one do In Madison? Well, there's the State Legislature (beautiful), the free zoo, and a boat ride on the lake.

But all those pale in comparison to the main attraction ... visiting John Hawks of John Hawks Weblog. I found him in a lab full of bones at the at the University of Wisconsin, Madison.

Delusions

I know I shouldn't pick on David Klinghoffer and the other IDiots at Evolution News & Views but, believe it or not, this is the best the IDiots have to offer.

I just can't resist posting this quotation from his latest post at: The Stubbornness of Their Ignorance.
Forget for a moment about who, Darwinists or Design advocates, is actually right. If you took a sample of ID folks and a sample of Darwin people, specifically those who have felt confident enough in their views to write about them for publication, and then quizzed each group about what arguments their opponents offer, there's no question that those from the ID community would know better what their opposites in the debate say.

Just look at ENV as a convenient illustration. We strive to keep up with toughest challenges, such as they are, from evolutionists. Now look at the competing Darwin blogs. Guys like PZ Myers & Co. concentrate their fire on naïve young-earth creationists. Jerry Coyne and his colleagues in the Darwin-defending business are careful to stay unaware of the very serious challenges to Darwinism from ID.
Wrong!

As it turns out, most of us know more about Intelligent Design Creationism than the average IDiot. As for evolution, I've yet to meet an IDiot who even comes close to understanding it, although Michael Behe and Michael Denton come pretty close.

Klinghoffer and his friends are deluding themselves if they think we don't know what they are saying and they are even more delusional if they think they understand evolution. We've proven time and time again that they don't.

Are we surprised? No, because the one thing all IDiots have in common is the God delusion—the biggest one of all.

My Review of Shapiro's Book Is Finally Published!

I wrote a review of Evolution: A View from the 21st Century for NCSE (National Center for Science Education). It was finished last September but NCSE delayed publication until they fixed up the website for Reports of the National Center for Science Education.

Here's the Table of Contents of the latest issue. All articles are free!

Shapiro threatens to respond to my review if he doesn't like it. I'm certain he won't like it. I'm looking forward to seeing how he responds to my criticisms, especially concerning his lack of knowledge of the history of evolutionary theory and his confusion about the meaning of the Central Dogma of Molecular Biology.


Carnival of Evolution #48

This month's Carnival of Evolution (48th version) is hosted by a developmental biologist at the University of Minnesota (Morris). He blogs at Pharyngula: Carnival of Evolution 48: The Icelandic Saga
I must begin by apologizing for my tardiness, especially since John Wilkins managed to post the last one on time. I was traveling in the 2½ weeks preceding the deadline for CoE, and the combination of spotty internet access, extreme jetlag (British Columbia to Germany to Iceland, where the sun hovered around the horizon all night long, just messed me up), and of course, the incredible distractions of exotic foreign lands, meant that I was disgracefully dilatory in putting it all together.

The next Carnival of Evolution (July) has no host. If you want to volunteer, contact Bjørn Østman. Bjørn is always looking for someone to host the Carnival of Evolution. He would prefer someone who has not hosted before. Contact him at the Carnival of Evolution blog. You can send articles directly to him or you can submit your articles at Carnival of Evolution.

Kirsty Duncan MP Objects to "Bias" in the Working Group on CIHR Funding of a Clinical Trial on "Liberation Therapy"

The previous post mentioned a recently published article on "liberation therapy" that referred to it as something akin to faith healing. It criticized the decision by Canada's CIHR to fund a clinical trial on the procedure. One of the authors of that article was Barry Rubin who served on the working group that recommended the trial.

This prompted a letter from Liberal MP Kirsty Duncan to Dr. Alain Beaudet, President of CIHR [MP lists concern with CIHR expert]. This is a blatant example of political interference and it should not be tolerated. Duncan should be reprimanded in Parliament.
Dear Alain,

Hello and warm wishes.

I am writing to you in order to bring an urgent issue to your attention. As you know, Dr. Barry Rubin is a member of CIHR's expert working group to study CCSVI. According to CIHR's website, the working group's mandate is: "The scientific expert working group will make recommendations on further studies including, if appropriate, a pan-Canadian interventional clinical trial that would evaluate the safety and efficacy of venous angioplasty in patients with MS, and will provide advice on the protocols to expedite such a trial (e.g. inclusion/exclusion criteria)."

Dr. Rubin is the fourth author on an article, 'The "Liberation Procedure" for Multiple Sclerosis: Sacrificing Science at the Altar of Consumer Demand', in the May, 2012 Journal of the American College of Radiology, Volume 9, Issue 5, Pages 305-308.

Alain, you and I have discussed conflict of interest numerous times before-both at committee and in correspondence. Surely, a member of the scientific expert working group publishing such a paper questioning clinical trials is in conflict with the group's mandate.

It is absolutely imperative that all members of the expert working group be independent, but equally important, be seen as independent, and not to have taken a position. Dr. Rubin can no longer be seen to be an independent judge of the scientific literature, as demonstrated by the conclusion of the paper.

Let me quote from the article, "Although some would agree that a randomized, blinded clinical trial is necessary to settle the issues raised in the controversy surrounding this procedure, others would agree that not all controversial procedures require such an expensive approach. Funding trials of a procedure that has minimal basis in rational, empirical knowledge seems questionable. At this point, the procedure rests in the same category of "medical" management as chelation therapy for atherosclerosis (which failed just such a trial), treatment of breast cancer with laser photodynamics, Laetrile for cancer, and other unproven therapeutics found in the retail sphere. When consumerism and patient advocacy groups pressure the scientific and political establishment, reasonable accommodation is warranted. The question is, What is reasonable? It may be that the operators believe in the therapy as much as the understandably desperate patients. The subsidiary question is, When is healing 'faith healing'?"

I will not comment on the science-or lack thereof-of the above.

It is extremely important to note that the first author of the paper, Dr. Michael Brant-Zawadzki of Hoag Memorial Hospital is being credited with prompting the FDA warning this past week.

There are important questions that need investigation. How did Dr. Brant-Zawadski and Dr. Rubin make contact? Were you apprised that Dr. Rubin was writing the article? Did you read the article pre-publication? When was the article accepted for publication? Were you or other officials at Health Canada and CIHR apprised of the FDA alert, and if so, when? Does CIHR support Dr. Rubin's behaviour? Are you concerned that the FDA alert-and this article-will prejudice/affect the ethical board reviews for CCSVI clinical trials? What action will be taken, as clearly this is a conflict of interest?

There is real concern amongst the CCSVI community that while the government fast-tracked Tysabri-a drug which was known to cause PML, and has now infected 232 people and killed 49 people-, and Gilenya, a drug which has now killed 11 people, and is currently under review in Canada (by the way, I am still waiting to hear from Paul Glover about the process for Health Canada's review of Gilenya)-, the government has been reticent about clinical trials for venous angioplasty, which is performed for Budd-Chiari syndrome, May-Thurner syndrome etc. across this country. Now a key panellist has not only come forward, but also published a paper with tremendous hyperbole, "sacrificing science at the altar", and members of the CCSVI community are concerned that a parallel process is being created-one in which the government says it will undertake clinical trials, while a key player appears to work actively to prevent this.

In closing, Dr. Haacke, Dr. McDonald, and Dr. Zamboni were not included in the August 26th, 2010 joint CIHR-MS Society meeting. The explanation given for their not being included in the meeting was that their work would be discussed, and including them might bias the discussion. Now, we have a member of CIHR's expert working group publishing and questioning clinical trials. Clearly, his position may bias the discussion.

Alain, this is extremely serious, and so, I look forward to hearing from you at the earliest time possible regarding Dr. Rubin's inclusion in the scientific expert working group.

Yours very truly,

Kirsty (Duncan)
Kirsty Duncan does not understand how science works and she does not understand that advocates of quack medicine are the ones who are "biased" against real science. It's not the scientists on the working group who caused the problem.


Canadian Government Allocates Funds to Investigate "Liberation Treatment" for Multiple Sclerosis: Sacrificing Science at the Altar of Consumer Demand

The Canadian Institutes of Health Research (CIHR) is the main funding agency for health research in Canada. Most of the research in my department is funded by CIHR grants and the number and size of those grants has been shrinking, with disastrous consequences for my colleagues.

Chronic cerebrospinal venous insufficiency (CCSVI or CCVI) is the name of a condition invented by an Italian doctor named Paolo Zamboni. He claims that it is the cause of multiple sclerosis. He also claims to have developed a procedure called "liberation treatment" or "liberation therapy" that will alleviate the symptoms of MS. It involves opening up some of the veins in a patient's neck in order to improve blood flow. He has been treating patients from all over the world for the past few years.

As you might have guessed, the treatment at his clinic is not free.

There has been enormous pressure on the Canadian and provincial governments to fund this treatment for MS patients, who otherwise have no hope of a cure. So far, most provinces have refused to pay for the treatment. In August 2010, CIHR announced that it would not fund research into something that does not exist [CIHR makes recommendations on Canadian MS research priorities].
Ottawa (August 31, 2010) – On Thursday, August 26, the Canadian Institutes of Health Research (CIHR), in collaboration with the MS Society of Canada, convened a meeting of leading North American experts in multiple sclerosis (MS) to identify research priorities for Canada in this area. Today, at a press conference in Ottawa, CIHR President Dr. Alain Beaudet announced the outcomes of the discussions and shared the recommendations he has made to the Honourable Leona Aglukkaq, Minister of Health.

"There was unanimous agreement from the scientific experts that it is premature to support pan-Canadian clinical trials on the proposed "Liberation Procedure," said Dr. Beaudet. "There is an overwhelming lack of scientific evidence on the safety and efficacy of the procedure, or even that there is any link between blocked veins and MS."
This is the right decision. Money is scarce and it would be criminal to devote any of it to quackery at the expense of legitimate scientific research.

But there's a catch.

Casey Luskin "Explains" Intelligent Design Creationism

Casey Luskin is upset with a philosopher named Christopher Pynes. Paynes had the audacity to suggest that one of the key features of Intelligent Design Creationism is ... creationism. According to Paynes, "supernaturalism is a necessary component of ID: there must be a designer" [AD HOMINEM ARGUMENTS AND INTELLIGENT DESIGN: REPLY TO KOPERSKI].

Luskin wants to remind everyone that Intelligent Design Creationism has nothing to do with a creator/designer [Professor Pynes Rails Against the "Straw-Man Fallacy" while Attacking a Straw-Man Version of Intelligent Design]. According to Luskin (a lawyer), Intelligent Design Creationism is a purely scientific theory that relies on: (a) proving that evolution is wrong, (b) detecting the creator/designer by examining nature.

On the primary1 grounds that it's always good to know your enemy, I present to you the best scientific grounds for Intelligent Design Creationism.
  • Studies of physics and cosmology continue to uncover deeper and deeper levels of fine-tuning. Many examples could be given, but this one is striking: the initial entropy of the universe must have been fine-tuned to within 1 part in 10(10^123) to render the universe life-friendly. That blows other fine-tuning constants away. New cosmological theories like string theory or multiverse theories just push back questions about fine-tuning, and would, if true, simply exacerbate the need for fine-tuning. This points to high levels of complex and specified information (CSI) in the cosmid architecture of the universe--information which in our experieince only comes from intelligence.
  • Mutational sensitivity tests increasingly show that DNA sequences are highly fine-tuned to generate functional proteins and perform other biological functions. Again, this is high CSI--which in our experience only comes from intelligence.
  • Studies of epigenetics and systems biology are revealing more and more how integrated organisms are, from biochemistry to macrobiology, and showing incredible fine-tuned basic cellular functions. The integrated nature of organismal body plans shows CSI throughout biological systems--in our experience, only intelligence can generate tightly intregrated multi-component blueprints.
  • Genetic knockout experiments are showing irreducible complexity, such as in the flagellum, or multi-mutation features where many simultaneous mutations would be necessary to gain an advantage. This is more fine-tuning--and in our experience, irreducibly complex machines arise only from intelligence.
  • The fossil record shows that species often appear abruptly without similar precursors, which represents mass-explosions of high CSI--something which requires an intelligent cause.
  • There have been numerous discoveries of functionality for "junk DNA." Examples include recently discovered functionality in some pseudogenes, microRNAs, introns, LINE and ALU elements. Intelligent design predicted this data.
If all of these things were true, then you'd predict that scientists would be flocking to church on Sundays. You'd also expect that the scientific literature would be full of papers proving the existence of God. It would be the most remarkable discovery in the history of humans.

A key part of Intelligent Design Creationism—the part that Casey Luskin is leaving out—is to explain why it has been so remarkably unsuccessful after 200 years of trying. That part has to do with the huge Darwinist conspiracy that forces scientists to tow the line and stick with atheistic Darwinism in spite of all the scientific evidence against it. If you read the blogs, you'll see that attacking scientists and Darwinism is the dominant theme. The "scientific" "evidence" for Intelligent Design Creationism is almost never mentioned.

Most of us scientists don't realize that we are part of such a conspiracy because we have been brainwashed into believing in evolution. However, a few god-fearing souls have seen the truth. Some of them are lawyers (Casey Luskin, Philip Johnson), some of them are philosophers, some of them claim to be mathematicians, and a few think they are scientists (Michael Behe, Jonathan Wells). The one thing they all have in common is that they are all IDiots.


1. The secondary grounds are to keep a record of the June 2012 "facts" because they will change soon enough.

Graduation Day

June is graduation month at the University of Toronto. There are various classes graduating every morning and afternoon for several weeks. (We have more than 70,000 students on three campuses, counting undergraduates, graduates, and enrollment in professional faculties.)

Today it's the turn of medical students. About 215 students just received their M.D. degrees. I'll be glad when it's all over 'cause the lineups at Tim Horton's1 are horrible.



Starbucks too, but I don't care about them.

A Platypus Describes Humans

Ryan Gregory invents The Platypus Fallacy to illustrate an important concept in evolution. Here's how a platypus describes humans. See if you can spot the problem.
The lineage of which humans are a part is a very ancient offshoot of our mammalian family tree, so it was 166 million years ago that we last shared a common ancestor with humans, and that puts them somewhere between mammals and reptiles, because they lack a lot of specialized characters that we have gained but the ancestral amniote also lacked; for instance, they have no electroreception, no bills, no webbed feet, and no venom. So we can use them to trace the changes that have occurred as we went from being a reptile, to having fur to making milk to having our specialized features.


Bruce Alberts Talks About Science Literacy

Bruce Alberts was president of the National Academy of Sciences (1993-2005), author of The Molecular Biology of the Cell, and winner of the Gairdner Award for his work on DNA replication. He was my Ph.D. supervisor. He is currently editor-in-chief of Science magazine. He has been interested in science education and science literacy for many decades so when he makes a comment about science education, it's worth listening to.

Here's a quote from a recent interview in PLoS Genetics [Scientist Citizen: An Interview with Bruce Alberts].
You look at the current political system in the US. It's incredibly depressing. These kinds of statements that “scientists only believe in climate change so that they can get a grant.” This kind of stuff couldn't be said if we actually had a population that understood what science is. We have a fantastic scientific community, and if we don't unleash them and give them credit for working on these things, then I don't think our country is going to prosper.

Every ten years the Academy publishes a booklet called “Science, Evolution and Creationism” [available online], and before the last one in 2008, the Academy hired one of the companies that put people behind a one-way mirror and interview them to see what they think about some new product. But this question was, “How do they think about science and creationism?”

And the staggering message from these college-educated adults is that they don't see any difference between science as a belief system and religion as a belief system. So basically, the preacher tells them what religious people believe, the scientists tell them what scientists believe, and [they think] “I can choose either one.” And the reason they can say that is that they don't understand what we call “science as a way of knowing”. That it is not a belief system, that it is an evidence-based community process.

This is just unbelievable, that our American public can determine our future without understanding the fundamental issues about scientific facts. If the population isn't prepared to deal with these kinds of issues, to think rationally and respect evidence, then I think the country is really in danger.
Like I say, science is a way of knowing that involves evidence and rationality. Now you know where I got that from.


The photo was taken at Bruce's 70th birthday party. It shows him with his first three graduate students: Keith Yamamoto (left), me (second from right), and Glenn Herrick (right).

Monday's Molecule #173

This is an easy one. We talked about this molecule in our lunch time seminar just a few minutes ago. It binds to lots of proteins.

Post your answer as a comment. I'll hold off releasing any comments for 24 hours. The first one with the correct answer wins. I will only post mostly correct answers to avoid embarrassment. The winner will be treated to a free lunch with a very famous person, or me.

There could be two winners. If the first correct answer isn't from an undergraduate student then I'll select a second winner from those undergraduates who post the correct answer. You will need to identify yourself as an undergraduate in order to win. (Put "undergraduate" at the bottom of your comment.)

Some past winners are from distant lands so their chances of taking up my offer of a free lunch are slim. (That's why I can afford to do this!)

In order to win you must post your correct name. Anonymous and pseudoanonymous commenters can't win the free lunch.

Winners will have to contact me by email to arrange a lunch date.

Comments are invisible for 24 hours. Comments are now open.

UPDATE: The molecule is malonyl-ACP where ACP stands for acyl carrier protein. The winners are Bill Chaney and Matt McFarlane. One other person got it right but didn't specify what "ACP" stood for. The most common error among those who came close was to call it malonyl-CoA.
