Science Guardian

Science Guardian incorporates New AIDS Review, Global Health Review, and Paradigm Overthrow.

Power and politics in science and health

Cool examination of hot debates

-----------------------------------------------

A site defending the values of science and good scientists who dissent in the paradigm wars of HIV/AIDS, cancer, evolution, global warming, nutrition, religious belief and other disputes over new and different ideas in science, health and economics.

We aim to expose truths buried in the literature and commonly overlooked by the media, and review novel claims without the group prejudice against modern Galileos, whistleblowers, distinguished mavericks, past or future Nobelists, or any other original and independent good minds (such as the noted scientists Peter Duesberg and Kary Mullis) who may question scripture.

Toadstools at the Times

June 28th, 2007

Public Editor speaks up for free debate, unaware of Times’ deadly HIV∫AIDS bias

Science joins in, giving Moore a free pass, but he trips up on excess

Even crackpot vegans deserve a hearing

clarkhoyt.jpgIn The Danger of the One-Sided Debate by Clark Hoyt the Public Editor of the New York Times talked last Sunday (June 24) about the Op-Ed page and discussed whether the Times has a responsibility not to run pieces by terrorist groups, and also, when carrying a politically provocative piece, whether it should make sure that an opposing view was also run.

This is interesting. Both issues seem highly relevant to the simmering paradigm quarrel in HIV∫AIDS, and the Times’ highly questionable behavior in mostly not carrying news and comment on the topic.

In fact over more than two decades, the paper of record has recorded as little news of the challenge to HIV as the cause of AIDS as possible. The name of Peter Duesberg has been featured a grand total of 16 times in 22 years, while the acronym “AIDS” has been mentioned 33,870 times. The only opinion the Times has carried in book reviews, columns and Op-Ed pieces have been squarely on the side of repressing the views of the distinguished scientist and his allies as decisively as possible.

moore.jpegThe title of the last Op-Ed piece on the topic by none other than our friend John P. Moore of Cornell, was Deadly Quackery, a label which told readers all they needed to know without even skimming the poorly argued and contemptuous column, whose style was as far from the collegial tone of genuine scientific debate as a drunken rape is from a chaperoned date.

The fact that the Times is highly vulnerable to the criticism of its own Public Editor in a great scientific battle of which he is unaware is what makes Mr Hoyt’s column dealing with two other issues on the Op-Ed page interesting.

Hamas terrorism, but how about HIV∫AIDS terrorism?

First, apparently last week the Times outraged some readers by giving a platform to a Hamas spokesman after its violent takeover of Gaza, so that he could make it clear “What Hamas Wants”.

One Joe Pensak of Massachusetts objected that this wasn’t balanced journalism, it was “more the dissemination of propaganda in the spirit of advocacy journalism” from a terrorist group which advocates flying the Palestinian flag over every inch of soil now occupied by Israel.

Replying to terrorist propaganda

The complaints of Joe and many other readers didn’t get very far with the editors. Andrew Rosenthal, editor of the editorial page, replied that he was under no obligation to “provide the kind of balance you find in news coverage” on the Op-Ed page and his deputy in charge of the page, David Shipley, explained that

“the news of the Hamas takeover of Gaza was one of the most important stories of the week….and this was out opportunity to hear what Hamas had to say.”

Presumably this is what they would reply to any complaints that their coverage of the HIV∫AIDS dispute has been one sided.

Hoyt speaks up for responsible journalism

Clark Hoyt in his role as the Public Editor mustered a judicious spirit in the wake of these unyielding pronouncements and summed up as follows:

Op-Ed pages should be open especially to controversial idea, because that’s the way a free society decides what’s right and what’s wrong for itself. Good ideas prosper in the sunshine of healthy debate, and the bad ones wither. Left hidden out of sight and unchallenged, the bad ones can grow like poisonous mushrooms.

Free debate the lifeblood of truth

mushroom.jpegWell, Clark, we certainly agree with those sentiments. So we wonder how is it that the Op-Ed page published this diatribe by John P. Moore of Cornell on June 11 last year and never ran anything presenting the other side of the HIV∫AIDS debate since?

The Op-Ed piece, Deadly Quackery, was, we are forced to say, a scientifically foolish piece of political propaganda from beginning to end, and certainly no definitive reply to the well established and long running objections to the HIV∫AIDS paradigm in the best peer reviewed journals.

Moore must have reminded discerning readers of the White House style of late in dealing with the crumbling of the Iraq rationale, since his piece consisted mainly of flat claims and denials without much reference to good evidence, served up with uncalled for ad hominem bias and garnished with misplaced appeals to concern for the social consequences of questioning HIV∫AIDS.

H.I.V. causes AIDS. This is not a controversial claim but an established fact, based on more than 20 years of solid science. It is as certain as the descent of humans from apes and the falling of dropped objects to the ground.

So why reiterate the obvious? Because lately, a bizarre theory has gained ground — one that claims that H.I.V. is harmless, and that the antiretroviral drugs that curb the growth of the virus cause rather than treat AIDS. Such talk sounds to most of us like quackery, but the theory has emerged as a genuine menace to public health in the United States and, particularly, in South Africa.

Neutral observers (such as this blog, politically speaking) could be forgiven for interpreting that as “a genuine menace to the welfare of those in science defending the paradigm and gaining large grants to research microbicides which only boost HIV transmission according to the latest studies”.
Here is the full text of Moore’s mad tilt if you wish to read it again:

Deadly Quackery
By JOHN MOORE and NICOLI NATTRASS

H.I.V. causes AIDS. This is not a controversial claim but an established fact, based on more than 20 years of solid science. It is as certain as the descent of humans from apes and the falling of dropped objects to the ground.

So why reiterate the obvious? Because lately, a bizarre theory has gained ground — one that claims that H.I.V. is harmless, and that the antiretroviral drugs that curb the growth of the virus cause rather than treat AIDS. Such talk sounds to most of us like quackery, but the theory has emerged as a genuine menace to public health in the United States and, particularly, in South Africa.

The theory, which we call AIDS denialism, has gained such currency with President Thabo Mbeki of South Africa that his administration is reluctant to expand access to antiretroviral drugs. Despite generous allocations from the country’s Treasury and substantial assistance from foreign donors, only a quarter of those needing antiretrovirals receive them. This response is poor by the standards of middle-income countries, but it is especially troublesome in South Africa, which has more H.I.V.-positive people than any other country.

American AIDS denialists are partly to blame for South Africa’s backsliding AIDS policy. Manto Tshabalala-Msimang, the health minister, has described antiretrovirals as poisons. She is supported in these views by Roberto Giraldo, a New York hospital technologist who says AIDS is caused by deficiencies in the diet, and who served on President Mbeki’s AIDS advisory panel in 2000. The minister promotes nutritional alternatives like lemons, garlic and olive oil to treat H.I.V. infection. Several prominent South Africans have died of AIDS after opting to change their diets instead of taking antiretrovirals.

Another American AIDS denialist, David Rasnick, a regular letter-writer to South African newspapers, absurdly claims that H.I.V. cannot be transmitted between heterosexuals. Mr. Rasnick now works in South Africa for a multinational vitamin company, the Rath Foundation, conducting clinical trials in which AIDS patients are encouraged to take multivitamins instead of antiretrovirals.

In the past, South Africa’s Medicines Control Council acted swiftly to curb such abuses, and the Medical Research Council condemned AIDS denialism. But recent high-level political appointments of administration supporters to both bodies have neutered their influence. In South Africa, AIDS denialism now underpins a lucrative nutritional supplements industry that has the tacit, and sometimes active, support of the Mbeki administration.

By courting the AIDS denialists, President Mbeki has increased their stature in the United States. He lent credibility to Christine Maggiore, a Californian who campaigns against using antiretrovirals to prevent transmission of H.I.V. from mothers to children, when he was photographed meeting her. Two years later, Ms. Maggiore gave birth to an H.I.V.-infected daughter, Eliza Jane, who acquired an AIDS-related infection last year and died at age 3.

Mother-to-child H.I.V. transmission is now rare in the United States, thanks to the widespread use of preventive therapy and the activities of organizations like the National Institutes of Health and the Elizabeth Glaser Pediatric AIDS Foundation. Sadly, this is not so in South Africa, where many children are born infected and then face short, painful lives. The health and lives of American children are also still under threat: a small clique of AIDS denialists is trying to block the provision of antiretrovirals to H.I.V.-infected children in the New York City foster care system.

Until recently, AIDS researchers and activists in the United States tended to regard the denialists with derision, assuming they would fade away. Unfortunately, this has not happened. Harper’s Magazine recently published an article by Celia Farber promoting the denialist view. There is a real risk that a new generation of Americans could be persuaded that H.I.V. either doesn’t exist or is harmless, that safe sex isn’t important and that they don’t need to protect their children from this deadly virus. A resurgence of denialism in the United States would have far reaching effects on the global AIDS pandemic, just as it already has in South Africa.

The AIDS denialists use pseudoscience and non-peer-reviewed Internet postings to bolster their false claims about H.I.V. The real facts about this virus have been uncovered by scientists supported by the National Institutes of Health, the British and South African Medical Research Councils, the Pasteur Institute and many other national research organizations. The public should seek AIDS truth from the latter sources.

It is sad when selling magazines and vitamin supplements is considered more important than promoting public health and scientific truth. The truth is that H.I.V. does exist, that it causes AIDS and that antiretroviral drugs can prevent H.I.V. transmission and death from AIDS. To deny these facts is not just wrong — it’s deadly.

John Moore is a professor of microbiology and immunology at Cornell University. Nicoli Nattrass is the director of the AIDS and Society Research Unit at the University of Cape Town.

Any question of consequences depends on who is right of course, which is not a matter which is settled by propaganda of this type, since as this blog has pointed out time and again the scientific literature with its study results consistently embarrasses and contradicts the paradigm enthusiasts such as Moore.

Mushrooms galore

mushpois.jpegMoore’s poisonous toadstool in this case was partially edible, actually, since it was a good example of how those who stand on uncertain ground go overboard in asserting their claims. Despite its adamant opening (”HIV is the cause of AIDS. etc”) it entirely begged the central question at issue ie who is right about HIV, the point on which weighing the “dangers” of criticism versus the “dangers” of making a very large mistake depends.

And as a horrendously one sided statement on an unsettled issue of international importance, it was a troubling indication of how partisan some scientists become when their paradigm investment is threatened. The Times was surely irresponsible in not running a counter column. A balancing reply was urgently needed if readers are to have a chance of understanding the reasons the backstage debate still is live and kicking after twenty three years.

No replies allowed

As it turned out not even one letter objecting to any of this was printed, and several were sent. A capitulation from the South African ambassador insisting that the government was rolling out ARVs at a record rate was printed under the title South Africa and AIDS .

What was desperately needed to restore balance was an Op-Ed in response, written from a scientific point of view contradicting every piece of unacceptable reasoning and evidence advanced by Moore in the socially irresponsible manner which characterizes his style of answering HIV∫AIDS doubts.

As we have said, to our mind this signals nothing more powerfully than his own internal doubt on the matter. This has to be what generates so much such adamant and unscientific certainty in his writing (see AIDSTruth.org, Moore’s counter dissident site for more excess along these lines) in lieu of productive discussion.

Thus in the end the Times piece was probably more of an embarrassment than an asset to the senior officers of the paradigm defense army with its fatal “Methinks he doth protest too much” style, as Queen Gertrude would have put it in Hamlet.

bulldogchampion.jpegWe dare say that as AIDSTruth.org has grown in adding more and more indiscreet ad hominem attacks and inadequate responses to scientific questions, the unfortunate Cornell research star is increasingly exposed as an energetic but half blind British bull dog whose barking and random grabbing of trouser cuffs does more to wake up sophisticated observers to the low grade politics of the field than a billboard in front of the Capitol.

Science’s Cohen fails again

The recent Science piece by Jon Cohen, HIV/AIDS: AIDSTruth.org Web Site Takes Aim at ‘Denialists’ celebrating the existence of his 150 views a day site allows Moore to demonstrate his talent for officiously closeminded insult to a sympathetic scribe who as we recall was once humiliated by Serge Lang, the Yale mathematician who was so appalled at Cohen’s blindness to the problems with official statistics in the HIV∫AIDS debate that he refused to be interviewed by him, writing to the editor of Science to tell him why.

As far as we are concerned AIDSTruth does the public a service by posting the text of this piece (Science 15 June 2007 Vol. 316. no. 5831, p. 1554) for the comparison it allows between Moore’s mushrooms and the quote from Peter Duesberg, who despatches the entire site with one verbal stake through the heart:

Peter Duesberg, a prominent cancer researcher at the University of California, Berkeley, whom colleagues have pilloried ever since he first questioned the link between HIV and AIDS in 1987, remains unswayed by the Web site, which he derides in an e-mail interview as a “scientifically worthless mix of ad hominems, opinions, intolerance, and religious energy–instead of a theory and facts.” Duesberg maintains that “many essential questions” about what he calls the “HIV-AIDS hypothesis” remain unanswered.

Seems to us that any rational reader seeing this remark side by side with Moore’s debating style will understand that good science is more likely to be found at Peter Duesberg’s site where all his excellent papers are immediately available than at AIDSTruth.org, whose style Moore is obviously very proud of but which may strike readers in a way that he does not expect:

Launched by AIDS researchers, clinicians, and activists from several countries, AIDSTruth.org offers more than 100 links to scientific reports to “debunk denialist myths” and “expose the denialist propaganda campaign for what it is … to prevent further harm being done to individual and public health.” The site also has a section that names denialists and unsparingly critiques their writings, variously accusing them of homophobia, “scientific ignorance of truly staggering proportions,” conspiracy theories, “the dogmatic repetition of the misunderstanding, misrepresentation, or mischaracterization of certain scientific studies,” and flat-out lies. “There was a perceived need to take these people on in cyberspace, because that’s where they operate mostly, and that’s where the most vulnerable people go for their information,” says immunologist John Moore, an AIDS researcher at the Weill Medical College of Cornell University in New York City.

Judge for yourself, dear reader, where the mushrooms are likely growing in HIV∫AIDS.

HIV/AIDS: AIDSTruth.org Web Site Takes Aim at ‘Denialists’

Vol. 316. no. 5831, p. 1554
Jon Cohen

For 20 years, a small but vocal group of AIDS “dissenters” has attracted international attention by questioning whether HIV causes the disease. Many AIDS researchers from the outset thought it best to ignore these challenges. But last year, another small and equally vocal group decided to counter the dissenters–whom they call “denialists”–with a feisty Web site, AIDSTruth.org. It has started to attract international attention itself. “It’s great,” says Mark Wainberg, head of the McGill AIDS Centre in Montreal, Canada. “We really need to get more people to understand that HIV denialism does serious harm. And we were in denial about denialism for a long time.”

Launched by AIDS researchers, clinicians, and activists from several countries, AIDSTruth.org offers more than 100 links to scientific reports to “debunk denialist myths” and “expose the denialist propaganda campaign for what it is … to prevent further harm being done to individual and public health.” The site also has a section that names denialists and unsparingly critiques their writings, variously accusing them of homophobia, “scientific ignorance of truly staggering proportions,” conspiracy theories, “the dogmatic repetition of the misunderstanding, misrepresentation, or mischaracterization of certain scientific studies,” and flat-out lies. “There was a perceived need to take these people on in cyberspace, because that’s where they operate mostly, and that’s where the most vulnerable people go for their information,” says immunologist John Moore, an AIDS researcher at the Weill Medical College of Cornell University in New York City.

Peter Duesberg, a prominent cancer researcher at the University of California, Berkeley, whom colleagues have pilloried ever since he first questioned the link between HIV and AIDS in 1987, remains unswayed by the Web site, which he derides in an e-mail interview as a “scientifically worthless mix of ad hominems, opinions, intolerance, and religious energy–instead of a theory and facts.” Duesberg maintains that “many essential questions” about what he calls the “HIV-AIDS hypothesis” remain unanswered.

Two factors led Moore and like-minded thinkers (who now number 11) to take off the gloves and hit back with AIDSTruth.org , which went online in March 2006. One was an article in that month’s issue of Harper’s magazine, “Out of Control, AIDS and the Corruption of Medical Science,” which chronicled Duesberg’s travails for challenging dogma and also questioned the safety and effectiveness of an anti-HIV drug that’s widely used to prevent transmission from an infected mother to her baby. Moore and other Web site co-founders wrote a 35- page critique of the article. The second trigger was the situation in South Africa. “Many people who had fought denialism in the early 1990s had lost interest in the subject, but in South Africa, it was at its peak,” explains another founder of the Web site, Nathan Geffen of South Africa’s Treatment Action Campaign. Geffen and others worried that his government might use the Harper’s article to justify further inaction. “South Africa has more people living with HIV than any other country, and it’s also been a place where AIDS denialism has had political support with terrible results.”

The no-frills Web site receives no funding, doesn’t pay contributors, and features no ads. It refuses to debate whether HIV causes AIDS, which it says “is as certain as the descent of humans from apes and the falling of dropped objects to the ground.” It has also posted articles by authors of peer-reviewed publications who believe their findings have been distorted by people trying to prove that HIV/AIDS is a ruse. “The denialists tend to be grotesquely inaccurate,” says Richard Jefferys, an activist with the Treatment Action Group in New York City who also helped start the site. “It’s almost like the more outrageously inaccurate the claim is, the more they repeat it.”

To the delight of Jefferys and others, a Supreme Court judge in Australia in April cited a debunking article on AIDSTruth.org in a closely followed case that involved a man convicted of endangering life for not revealing he was infected with HIV to sexual partners. The man appealed, claiming that no studies prove HIV causes AIDS. His defense consisted of two “expert” witnesses, one of whom was extensively questioned about allegations that she had misused a researcher’s results on sexual transmission of HIV. The questions were inspired by an editorial posted on AIDSTruth.org . The judge concluded that neither defense witness–both of whom are branded as denialists on AIDSTruth.org –was qualified to express opinions on these questions. “There’s a constant concern that by rebutting these things, you’re giving them more credence–there’s a thin line between slaying the monster and feeding it,” says Jefferys. “The judge’s decision made the Web site seem really worthwhile.”

AIDSTruth.org has seen its popularity rise from about 60 unique visits a day to 150. But as Moore notes, “we’re certainly not high up in the Google rankings.” Then again, he argues, any effective rebuke to the “anti-scientific” opinions that attract so much attention is worth the effort. “If you ignore the denialists, they’re not going to disappear,” says Moore. “And they don’t like the fact that we can get in their faces. They’re used to being unchallenged.”

Intellectual terrorists at work

mushpoi.jpegBut good ideas prosper in the sunshine of healthy debate, as the man said, so why was Moore allowed to get away with pulling the Times into his strategy of not allowing AIDS dissent a voice if he can possibly help it? Especially since the whole affair fits very well the definition of allowing terrorists a voice in the Times as propaganda without reply, as Joe objected.

In our view Moore and his fellow members of the goon quad in the defense of the HIV∫AIDS paradigm can be counted as intellectual terrorists because they perpetrate intellectual violence in the form of ad hominem attacks, refusal to debate, and censorship of recognition and reporting of a respectable paradigm dissent, not to mention phone calls to employers and colleagues of dissidents which have been reported from Moore and other paradigm priests.

The valid debate is thus veiled from the unknowing public even though it has been led by a scientist who without argument from anyone is an elite practitioner and academic whose objections have to be taken seriously, especially when the uncollegial public responses to him are not on the same intellectual level.

********************************************
This failure of reporting and editing will quite possibly be the greatest black mark in the newspaper’s history, far greater than the failure of individual reporters.
***************************************************

With its violence and propaganda, by any reasonable standard this style of response is social terrorism with its flexing of political power, financial sanctions and professional ostracism, and if the Times coverage is not balanced outsiders will (as they do) get quite the wrong impression of the value of the points that are made by respectable critics against a paradigm whose logical flaws, according to the scientific literature, have been fatal from the very beginning of a long flight sustained scientifically only by hot air and misrepresentation of evidence.

Historical threat to Times’ stature

judithmiller.jpgHere is the crux of the problem: we have the public debate of a very large issue affecting the health of tens of millions cut off by Moore and his colleagues with the active cooperation of the world’s greatest newspaper, not to mention the leading science journal in the US. Not a shining example of the way the New York Times should meet its responsibilities and one that when exposed in the fullness of time will reduce the trust of readers a very large notch.

This failure of reporting and editing will quite possibly be the greatest black mark in the newspaper’s history, far greater than the failure of individual reporters such as Judith Miller

Even before she served 85 days in jail last summer for refusing to testify about her conversations with then-vice presidential aide Lewis “Scooter” Libby, Miller wrote, she had “become a lightning rod for public fury over the intelligence failures that helped lead our country to war.” Miller, whose prewar stories about whether Iraq harbored weapons of mass destruction were later disavowed by the Times as inaccurate, said she regretted “that I was not permitted to pursue” the story further.

or Jason Blair:

Times Reporter Who Resigned Leaves Long Trail of Deception

A staff reporter for The New York Times committed frequent acts of journalistic fraud while covering significant news events in recent months, an investigation by Times journalists has found. The widespread fabrication and plagiarism represent a profound betrayal of trust and a low point in the 152-year history of the newspaper.

jayson-blair.jpgThe reporter, Jayson Blair, 27, misled readers and Times colleagues with dispatches that purported to be from Maryland, Texas and other states, when often he was far away, in New York. He fabricated comments. He concocted scenes. He lifted material from other newspapers and wire services. He selected details from photographs to create the impression he had been somewhere or seen someone, when he had not.

Vegans should be allowed a defense

Meanwhile the fount of wisdom that is Clark Hoyt goes on to consider the similar imbalance of the Op-Ed page in publishing a critique of extreme vegans (*pron. according to the dictionary with a soft g not a hard one, in case you didn’t know) without including a voice of dissent.

This wasn’t the case, however, with a May 21 op-ed by Nina Planck, an author who writes about food and nutrition. Sensationally headlined Death by Veganism,” Planck’s piece hit much closer to home than Yousef’s. It said in no uncertain terms that vegans — vegetarians who shun even eggs and dairy products — were endangering the health and even the lives of their children. A former vegan herself, Planck said she had concluded “a vegan pregnancy was irresponsible. You cannot create and nourish a robust baby merely on foods from plants.”

Her Exhibit A was a trial in Atlanta in which a vegan couple were convicted of murder, involuntary manslaughter and cruelty in the death of their 6-week-old son, who was fed mainly soy milk and apple juice and weighed only 3.5 pounds. The column set off a torrent of reader e-mail that is still coming in — much of it from vegans who send photos of their healthy children or complain bitterly of being harassed by friends and relatives using Planck’s column as proof that their diet is dangerous.

In this it’s pretty clear that the couple simply starved the baby to a skeletal death and the issue of whether all nutrients necessary to health are included in a vegan diet is not really involved.

But Planck had taken the opportunity to launch a severe critique, and Hoyt reasonably felt that it was unfair not to provide some rebuttal, and let readers decide who was right.

If there was another side, a legitimate argument that veganism isn’t harmful, Planck didn’t tell you — not her obligation, Rosenthal and Shipley say. But unlike the Middle East, The Times has not presented another view, or anything, on veganism on its op-ed pages for 16 years. There has been scant news coverage in the past five years.

There is another side.

Rachelle Leesen, a clinical nutritionist at the Children’s Hospital of Philadelphia, told me that Planck’s article “was extremely inflammatory and full of misinformation.” She and her colleague Brenda Waber pointed me to a 2003 paper by the American Dietetic Association, the nation’s largest organization for food and nutrition professionals. After reviewing the current science, the A.D.A., together with the Dietitians of Canada, declared, “Well-planned vegan and other types of vegetarian diets are appropriate for all stages of the life cycle, including during pregnancy, lactation, infancy, childhood and adolescence.”

Even though Planck replied with 250 studies from the ADA she seems to be grinding the wrong axe since the child had obviously died of not enough food, rather than the wrong kind, says Hoyt. So a reply was valid and desirable.

Charles Boring, the Fulton County prosecutor who handled the case, told me it was “absolutely not” about veganism. Planck and Shipley said they were aware of the prosecutor’s contention. Shipley said, “We were also aware, though, that the convicted couple continues to insist that they were trying to raise their infant on a vegan diet.”

But the jury didn’t believe them, and leaving that out put Planck’s whole column on a shaky foundation.

Op-ed pages are for debate, but if you get only one side, that’s not debate. And that’s not healthy.

Why so many mushrooms, Clark?

We heartily agree with the last sentence and suggest that Clark trot over to the Science Section and ask the CDC trained Larry Altman why they have not found someone to reply to the Moore Op-Ed “Deadly Quackery” in over a year.

mushroompoisonous.jpegCould it be by some chance that it reflects the power of the sleek-suited Dr Anthony Fauci at NIAID and his edict many, many years ago in the AAAS Observer in 1989 that

“AIDS has created a whole new interaction between scientists and the press (…) Journalists who make too many mistakes or who are too sloppy are going to find that their access to scientists may diminish”?

Surely not. It is difficult to imagine that one bureaucrat, even a man who was called a hero by President Reagan, could have such influence over the greatest newspaper in the world.

But what are those poisoned mushrooms doing growing on the desks of so many editors at the New York Times?

The New York Times

The Public Editor
The Danger of the One-Sided Debate
By CLARK HOYT

THE op-ed page of The New York Times is perhaps the nation’s most important forum for airing opinions on the most contentious issues of the day — the war in Iraq, abortion, global warming and more.

“We look for opinions that are provocative,” said Andrew Rosenthal, the editor of the editorial page. “Opinions that confirm what you already thought aren’t that interesting.”

But some opinions provoke more than others. Two very different columns by guest contributors, one last week and one last month, caused enormous reader outcries and raised important questions. Are there groups or causes so odious they should be ruled off the page? If The Times publishes a controversial opinion, does it owe readers another point of view immediately? And what is the obligation of editors to make sure that op-ed writers are not playing fast and loose with the facts?

The most recent column was by Ahmed Yousef, a spokesman for Hamas, the party elected to lead the Palestinian government and a group dedicated to the destruction of Israel. He wrote Wednesday about “What Hamas Wants.”

Many readers were outraged, complaining that The Times had provided a platform for a terrorist. One, Jon Pensak of Sherborn, Mass., said that allowing Yousef space in The Times “isn’t balanced journalism, it is more the dissemination of propaganda in the spirit of advocacy journalism.”

Well, yes. The point of the op-ed page is advocacy. And, Rosenthal said, “we do not feel the obligation to provide the kind of balance you find in news coverage, because it is opinion.”

David Shipley, one of Rosenthal’s deputies and the man in charge of the op-ed page, said: “The news of the Hamas takeover of Gaza was one of the most important stories of the week. … This was our opportunity to hear what Hamas had to say.”

I agree that Yousef’s piece should have run, even though his version of reality is at odds with the one I understand from news coverage. He wrote blandly, for example, about creating “an atmosphere of calm in which we resolve our differences” with Israel without mentioning that Hamas is officially dedicated to raising “the banner of Allah over every inch of Palestine,” which would mean no more Israel.

Op-ed pages should be open especially to controversial ideas, because that’s the way a free society decides what’s right and what’s wrong for itself. Good ideas prosper in the sunshine of healthy debate, and the bad ones wither. Left hidden out of sight and unchallenged, the bad ones can grow like poisonous mushrooms.

Rosenthal and Shipley said that, over time, they try to publish a variety of voices on the most important issues. Regular op-ed readers have seen a wide range of views on the Israeli-Palestinian conflict and have a lot of other information to help judge Yousef’s statements.

This wasn’t the case, however, with a May 21 op-ed by Nina Planck, an author who writes about food and nutrition. Sensationally headlined “Death by Veganism,” Planck’s piece hit much closer to home than Yousef’s. It said in no uncertain terms that vegans — vegetarians who shun even eggs and dairy products — were endangering the health and even the lives of their children. A former vegan herself, Planck said she had concluded “a vegan pregnancy was irresponsible. You cannot create and nourish a robust baby merely on foods from plants.”

Her Exhibit A was a trial in Atlanta in which a vegan couple were convicted of murder, involuntary manslaughter and cruelty in the death of their 6-week-old son, who was fed mainly soy milk and apple juice and weighed only 3.5 pounds. The column set off a torrent of reader e-mail that is still coming in — much of it from vegans who send photos of their healthy children or complain bitterly of being harassed by friends and relatives using Planck’s column as proof that their diet is dangerous.

If there was another side, a legitimate argument that veganism isn’t harmful, Planck didn’t tell you — not her obligation, Rosenthal and Shipley say. But unlike the Middle East, The Times has not presented another view, or anything, on veganism on its op-ed pages for 16 years. There has been scant news coverage in the past five years.

There is another side.

Rachelle Leesen, a clinical nutritionist at the Children’s Hospital of Philadelphia, told me that Planck’s article “was extremely inflammatory and full of misinformation.” She and her colleague Brenda Waber pointed me to a 2003 paper by the American Dietetic Association, the nation’s largest organization for food and nutrition professionals. After reviewing the current science, the A.D.A., together with the Dietitians of Canada, declared, “Well-planned vegan and other types of vegetarian diets are appropriate for all stages of the life cycle, including during pregnancy, lactation, infancy, childhood and adolescence.”

Planck said she was aware of the A.D.A.’s position but regarded it as “pandering” to a politically active vegan community.

I won’t rehash the scientific dispute in a case in which Planck has her experts and the A.D.A. paper cited more than 250 studies, but I think The Times owes its readers the other side, published on the op-ed page, not just in five letters to the editor that briefly took issue with her.

I even question Planck’s Exhibit A, poor little Crown Shakur, who was so shriveled at his death that doctors could see the bones in his body. His death, she wrote, “may be largely due to ignorance. But it should prompt frank discussion about nutrition.”

Maybe, if by nutrition you mean a discussion about whether you feed a baby anything at all.

The prosecutor argued — and the jury believed — that Crown’s parents intentionally starved him to death. News coverage at the time said that the medical examiner, doctors at the hospital to which Crown’s body was taken and an expert nutritionist testified that the baby was not given enough food to survive, regardless of what the food was.

Charles Boring, the Fulton County prosecutor who handled the case, told me it was “absolutely not” about veganism. Planck and Shipley said they were aware of the prosecutor’s contention. Shipley said, “We were also aware, though, that the convicted couple continues to insist that they were trying to raise their infant on a vegan diet.”

But the jury didn’t believe them, and leaving that out put Planck’s whole column on a shaky foundation.

Times essay salutes need for Darwin 2.0 at last

Douglas Erwin’s decency misleads him somewhat

Paradigm change not joyful to some, Doug

darwin.jpegAnyone who has heard top creationist intellectuals in action knows they are as clever as any Jesuit in pointing to holes in our understanding of evolution and how it works, holes in which they find God hiding, but which others expect to be filled with science anon.

As the fine exhibition on Darwin at the American Museum of Natural History last year showed, this cleverness has led to a certain panic among evolutionists, who too often have pretended that the gaps don’t exist, and that mutation plus the Darwinian struggle explains all, as in the “modern synthesis”.

The exhibition studiously avoided all mention of the creationist argument, treating it as beneath contempt, which it probably is, logically speaking. But as we have noted in previous posts, much has been learned in the past decade which is filling in the gaps in our understanding of how new species pop up, which is the fundamental puzzle the modern synthesis doesn’t solve.

This morning the New York Times Science section is devoted to a nice set of pieces entirely devoted to “Evolution” and saluting these advances, and the changes in the paradigm they herald. “This special issue of the Science Times is an attempt to help make sense of evolution, as a living, changing science” says the introduction.

The key essay on the paradigm issue is Darwin Still Rules, but some Biologists Dream of a Paradigm Shift by Douglas H. Erwin, a senior scientist at the Smithsonian’s National Museum of Natural History and a research professor at the Santa Fe Institute, home of the farthest out, beyond the edge scientific and other thinkers in the nation, and possibly on the planet.

Douglas Erwin is Senior Scientist and Curator in the Department of Paleobiology at the Smithsonian Institution’s National Museum of Natural History and a part-time research professor at the Santa Fe Institute. He began studying the end-Permian mass extinction in the early 1980s and has traveled many times to China, South Africa, and Europe seeking its causes and examining its consequences. His work on the end-Permian event stems from an interest in evolutionary innovations; extinction events are classically seen as generators of evolutionary novelty. Erwin studies patterns and time frames of biotic recovery, focusing particularly on gastropods of the Permian and Triassic. Erwin takes a broad look at the evidence and controversies concerning the end-Permian event in his book Extinction: How Life on Earth Nearly Ended 250 Million Years Ago (Princeton University Press, 2006).

“Is Darwin due for an upgrade?” Erwin asks and the answer he gives in a tactfully fudged manner aiming not to offend anybody is “yes”. But it is hard to nail down exactly why. He focuses on the new findings in evolutionary developmental biology, or “evo-devo”, which have shown how much goes on in the embryo where little changes can alter the shape of the resulting life form wholesale.

The developmental mechanisms involved can be experimented with, Erwin notes, with “exciting” results involving wingspots on butterflies and the gut of sea urchins and starfish, showing which genes are the essential core genes or kernel which cannot be modified without stopping the embryo’s development completely.

The Achilles’ heel of the modern synthesis, as noted by the philosopher Ron Amundson, is that it deals primarily with the transmission of genes from one generation to the next, but not how genes produce bodies. The recent discoveries in the new field of evolutionary developmental biology, or evo-devo, that the gene Pax-6 controls the formation of eyes in mice and humans, Nkx2.5 heart formation, and a suite of other genes the formation of the nervous system, has provided a means to investigate the genetic and developmental mechanisms influencing how the form of organisms has evolved, not just their genes. Perhaps the most exciting area in evolution is in exploring how rewiring the circuitry of genes produces different arthropod appendages, or wingspots on butterflies.

Eric H. Davidson, a colleague of mine at CalTech, has dissected the network of interactions between the genes that build the gut of sea urchins and starfish during development. When he compares these gene networks, there is a core of about five genes whose interactions are essential to forming the gut, and which have been preserved for some 500 million years.

One advantage developmental biologists have over paleontologists is that they can experiment on the development of these animals. Most of the genes in this network can be removed, and the developing embryo finds a way to compensate. But these five core genes, which form what Davidson calls a kernel, cannot be modified: change any one of them and no embryo forms at all.

Unfortunately he stops short of clearly explaining how this line of research will produce additional evolutionary mechanisms to add to Darwin and mutation. If anything he emphasizes how the mechanisms being elucidated in the embryo’s developmental process lead to restrictions on the path along which the organism can evolve. “Once the kernel formed it locked development onto a certain path.”

What creationists keep pointing out is the lack of adequate (to them) explanation of how complex systems such as eyes arise from random mutation and survival competition, and what Erwin describes doesn’t answer this question, though he hints that it will.

What we need we daresay is something more along the lines of Lynn Margulis’ conception of simpler elements merging to form more complex species. She is surely right on the micro level in saying that microorganisms evolved through symbiotic merging, and that one way to view a human being is a vast agglomeration of cellular life forms.

But do larger forms merge in some way to form new species? Presumably not, but something has to account for the abrupt transition between species observed in the fossil record, and the modern synthesis doesn’t do it.

Transitions between species documented by the fossil record seemed to be abrupt, perhaps too abrupt to be explained by the modern synthesis. If this were generally true, it could render irrelevant much of natural selection occurring within species, because just as mutations are produced randomly with respect to the needs of a species, with selection shaping these into new adaptations, new species might evolve randomly with species selection shaping them into evolutionary trends. This challenge was greeted with less than fulsome praise by evolutionary biologists studying changes within species. The resulting hubbub has yet to fully die down. But the newer work cuts closer to the core of the modern synthesis, and is potentially more revolutionary, because it addresses the fundamental question of how really new things happen in the history of life. What brought about the origin of animals, or the invasion of land?

Erwin’s essay doesn’t seem to suggest anything very specific as an additional mechanism, except a sort of modern mix of Lamarck and Gaia whereby species might change their environment and this might feed back into their own adaptation.

But just as the erosive power of a river changes the future options for the course of the river, so evolution itself changes future evolutionary possibilities. This can happen in simple ways, as termites construct their own environment by building termite mounds. These mounds may last for dozens or hundreds of years and provide a sort of ecological inheritance for generations of termites.

The first cyanobacteria turned carbon dioxide into oxygen and set off a revolution that completely changed the chemistry of the oceans and atmosphere. Most species modify their environment and this often changes how selection affects them: they construct, at least in part, their own environment. As evolutionary biologists we have little understanding of what these processes mean for evolution.

All in all, the essay hints at expected change without really showing much movement in the paradigm to date. But even that simple acknowledgment of the need for the paradigm to evolve is refreshing after the peculiar silence on the topic at the American Museum of Natural History in New York.

Does all this add up to a new modern synthesis? There is certainly no consensus among evolutionary biologists, but development, ecology, genetics and paleontology all provide new perspectives on how evolution operates, and how we should study it. None of these concerns provide a scintilla of hope for creationists, as scientific investigations are already providing new insights into these issues. The foundations for a paradigm shift may be in place, but it may be some time before we see whether a truly novel perspective develops or these tensions are accommodated within an expanded modern synthesis.

The political innocence of good scientists

darwinbeagle.jpegOne thing we did conclude as soon as we started reading the Erwin rumination was that among real scientists who are genuinely more interested in reality that what works career-wise, there is still a certain naivete as to what is happening in some realms of research where scientific activity is being warped by vast sums of money, where paradigms with no proven merit whatsoever may be sustained and promoted far beyond their due date of replacement by forces of human nature far beyond science

Here is how Erwin views the possibility of a paradigm shift - with excitement, joy and anticipation.

There is nothing scientists enjoy more than the prospect of a good paradigm shift.

Paradigm shifts are the stuff of scientific revolutions. They change how we view the world, the sorts of questions that scientists consider worth asking, and even how we do science. The discovery of DNA marked one such shift, the theory of plate tectonics another.

Many scientists suffer from a kind of split personality. We believe that this is the most exciting time to be working while yearning for the excitement of a revolution. What ambitious scientist would not want to be part of a paradigm shift? Not surprisingly, this yearning occasionally manifests itself in proclamations that a revolution is at hand.

This is how good scientists think and feel. How telling that there is no sign whatsoever of these attitudes in HIV∫AIDS.

If anything, the exact opposite prevails. Top scientists in HIV∫AIDS seem to view the prospect of paradigm change with the same distaste they might feel at discovering a dead rat amid the bounteous feast they are dining on royally at the top table.

Essay
Darwin Still Rules, but Some Biologists Dream of a Paradigm Shift
By DOUGLAS H. ERWIN

Is Darwin due for an upgrade? There are growing calls among some evolutionary biologists for just such a revision, although they differ about what form this might take. But those calls could also be exaggerated. There is nothing scientists enjoy more than the prospect of a good paradigm shift.

Paradigm shifts are the stuff of scientific revolutions. They change how we view the world, the sorts of questions that scientists consider worth asking, and even how we do science. The discovery of DNA marked one such shift, the theory of plate tectonics another.

Many scientists suffer from a kind of split personality. We believe that this is the most exciting time to be working while yearning for the excitement of a revolution. What ambitious scientist would not want to be part of a paradigm shift? Not surprisingly, this yearning occasionally manifests itself in proclamations that a revolution is at hand.

To understand the current tumult it helps to understand how our evolutionary framework developed. It was constructed from the 1930s to 1950s by early geneticists, paleontologists and others, who disagreed about the efficacy of natural selection in driving evolutionary change (Darwin’s big idea) and about the nature of the underlying genetic variation upon which natural selection could act. What they came to agree on was called the modern synthesis, and it established an intellectual zeitgeist that continues today, and has been continually adapted, in the best evolutionary fashion, to encompass new discoveries.

That synthesis holds that mutations to DNA create new variants of existing genes within a species. Natural selection, driven by competition for resources, allows the best-adapted individuals to produce the most surviving offspring. So adaptive variants of genes become more common. Although selection is often seen, even by biologists who should know better, as primarily negative, removing poorly adapted individuals, Charles Darwin understood that it was a powerful creative tool.

It is the primary agent in shaping new adaptations. Computer simulations have shown how selection can produce a complex eye from a simple eyespot in just a few hundred thousand years.

In the past few years every element of this paradigm has been attacked. Concerns about the sources of evolutionary innovation and discoveries about how DNA evolves have led some to propose that mutations, not selection, drive much of evolution, or at least the main episodes of innovation, like the origin of major animal groups, including vertebrates.

Comparative studies of development have illuminated how genes operate, and evolve, and this places less emphasis on the gradual accumulation of small genetic changes emphasized by the modern synthesis. Work in ecology has emphasized the role organisms play in building their own environments, and studies of the fossil record raise questions about the role of competition. The last major challenge to the modern synthesis came in the 1970s and 1980s as my paleontological colleagues, including the late Stephen Jay Gould, argued for a hierarchical view of evolution, with selection occurring at many levels, including between species.

Transitions between species documented by the fossil record seemed to be abrupt, perhaps too abrupt to be explained by the modern synthesis. If this were generally true, it could render irrelevant much of natural selection occurring within species, because just as mutations are produced randomly with respect to the needs of a species, with selection shaping these into new adaptations, new species might evolve randomly with species selection shaping them into evolutionary trends. This challenge was greeted with less than fulsome praise by evolutionary biologists studying changes within species. The resulting hubbub has yet to fully die down. But the newer work cuts closer to the core of the modern synthesis, and is potentially more revolutionary, because it addresses the fundamental question of how really new things happen in the history of life.
