Neuroscience: Neurons arranged in "extraordinary precision"

by Denyse O'Leary
ARN correspondent

In "When Listening to Music, Your Brain Is ‘Moving’ Even If You Are Not," a news release from the Society for Neuroscience (10/15/06), we learn,

One of the best-studied features in orientation maps is known as a pinwheel, a small region in which all orientations are represented in segments that appear to come to a point. "A long-standing question is, 'How are neurons arranged in the pinwheel centers?'" says R.C. Reid, PhD, of Harvard Medical School.

Reid provided the answer by using two-photon calcium imaging, which determines the physiological response of hundreds of cells simultaneously as well as their precise location in the cortical circuit.

"By recording from hundreds to thousands of neurons at each pinwheel center, we demonstrated that pinwheel centers are remarkably well organized," he says.

"Neurons selective to different orientations are arranged in an orderly manner even in the very center," he adds. "There was virtually no mixing of cells with different orientation preferences even at the center. Thus, pinwheel centers truly represent singularities in the cortical map." This finding is suggesting extraordinary precision in the development of cortical circuits.

and much else.

Ignore all the yap about evolution in the article, which is - as typical - intended to distract attention from the obvious conclusion.

Where Mycologists Go To Church On Sundays

By Robert Deyes
ARN Correspondent

When it comes to academic triumphs and laudatory honors it can be said that mycologist Paul Stamets has his fair share. Stamets has authored six books on mushrooms, holds over twenty patents, is a winner of the Collective Heritage Institute's Bioneers Award and owns a wholesale business selling alternative medicines. Today he also runs a facility that boasts twenty four laminar flow benches across four laboratories processing between 10-20 thousand kilos of mycelia each week. He has close to a thousand mycelium cultures growing at any given time and is renowned across the world for his view of fungi as the 'grand molecular dissemblers of nature'.

Stamets describes himself in his youth as a hippy with a stuttering habit who could not look people in the eye. He also fondly recalls once telling his charismatic Christian mother that the forest is where he goes to church on Sundays. He spent many years as a microscopist at the Evergreen State College in Washington studying mushroom mycelia with the aid of an electron microscope. There he developed an intense passion for all things fungal even to the extent that he now occasionally appears in public sporting a hat made from Amadou- a fungus that, he boldly maintains, was essential for the portability of fire during man's much-heralded migration out of Africa.

When it comes to mushrooms, Stamets' most radical concept, and perhaps his most attractive one, draws on a human parallel. In fact he proposes that that organized networks of mycelia under our feet form the earth's own 'internet' of sorts carrying antibiotics and enzymes as well as huge numbers of signaling chemicals across trillions and trillions of end branchings. In short, he sees our own Internet superhighway as a mere replica of a highly-successful system that already exists in nature's own backyard. Perhaps surprisingly these networks are not confined to land habitats. Indeed aquatic underwater mushrooms have been discovered in the streams of southern Oregon and mycologists are now busily investigating how these hydrophiles survive and affect surrounding ecosystems.

Agarikon is yet another fungal species that gets mycologists such as Stamets visibly excited. Otherwise known as the 'elixir of long life', this impressively-sized fungus has been used for years as an effective treatment for respiratory diseases such as tuberculosis and is now known to exhibit a very potent effect against the smallpox and flu viruses. There is strong evidence that the active anti-virals in Agarikon might also serve well in the present-day combat against H1N1 and H5N1. In fact so critical to human health are the medicinal properties of this remarkable organism that Stamets has embarked on his own mini-crusade to create the largest Agarikon genomic DNA library in the world.

On a more serious note, many environmentalists claim that today we are fully engaged in the biggest mass extinction event that our planet has ever known. Stamets is not one to shy away from sounding alarm bells and boldly adheres to the claim that 50% of all known species on our planet could become extinct over the next 100 years if swift action is not taken. His use of oyster mushroom mycelia to remove oil pollution is an outstanding example of how we might avert such a bleak endpoint. These saprophytic fungi are gateway species that break down toxic waste through the action of specialized enzymes and thereby allow damaged ecosystems to flourish and rebound. Oyster mushrooms have also been shown to have a dramatic effect on bacterial titers destroying coliform bacteria and Staphylococcus in contaminated waters.

The environmental resiliency of fungi has long fascinated mycologists, and future mycotechnologies might build on this salient property. While Prototaxites- a 30-foot long, 3-foot high mushroom that lived 350-420 million years ago stands as the archetypal giant fungus, the twenty two-hundred acre, one cell thick mycelium mat of Armillaria ostoyae (honey mushroom) now holds the record for the largest organism in the world. Thermo-resilient symbionts such as Curvularia confer a viral-dependent heat tolerance on many grasses allowing them to grow at elevated temperatures, as high as 104 F in some cases.

Fungi can be described as being parasitic, saprophytic, micorrhizal or endophytic in their modes of deriving nourishment. This so-called 'mycological guild' of complementary fungi is what gives rise to a healthy ecosystem. The interactivity of these fungi and other organisms is clearly visible in ant cultivars of the Lepiota mushroom which are used by thatch ants to stop a particularly aggressive parasitic fungus called Escovopsis from invading their nests. In a converse strategy, Metarhizium is a parasitic fungus that kills carpenter ants and is therefore finding application in the protection of buildings from these would-be aggressors. By using the non-sporulating stage of Metarhizium, Stamets has surpassed the carpenter ants' own ability to keep the fungus at bay thereby providing him with an effective treatment against carpenter ant infestations.

Despite such mycotechnological advances, Stamets describes the current state of the field as being under-respected, underappreciated and underfunded. Most importantly he remains steadfastly focused on restoring ecosystems for the enjoyment of generations to come. For those of us actively involved in the evolution/ID debate, Stamets' findings are likewise poignantly relevant. In fact he makes a stunning claim regarding computer and fungal networks noting how "we were destined to create the computer Internet at a time when the earth is in crisis".

That our understanding of network theory and its importance in fungal bioremediation should coincide with our earth's need for ecological intervention introduces a teleological, purposeful perspective to life that contradicts the contingency of orthodox Darwinism. After all a cosmos that is fashioned towards such an endpoint is incompatible with the random, directionless tenet of natural selection. As for the Christian faithful there is one proclamation that makes sense in our current predicament: Thank God that the forests are where mycologists choose to go to church on Sundays!

Gap tooth creationist moron flubs stupid superstitions

by Denyse O'Leary
ARN correspondent

Even though I am not a creationist by any reasonable definition, I sometimes get pegged as the local gap tooth creationist moron. (But then I don't have gaps in my teeth either. Check the unretouched photos.)

As the best gap tooth they could come up with, a local TV station interviewed me about "superstition" the other day.

The issue turned out to be superstition related to numbers. Were they hoping I'd fall in?

The skinny: Some local people want their house numbers changed because they feel the current number assignment is "unlucky."

Look, guys, numbers here are assigned on a strict directional rota. If the number bugs you so much, move.

Don't mess up the street directory for everyone else. Paramedics, fire chiefs, police chiefs, et cetera, might need a directory they can make sense of. You might be glad for that yourself one day.

Anyway, I didn't get a chance to say this on the program so I will now: No numbers are evil or unlucky. All numbers are - in my view - created by God to march in a strict series or else a discoverable* series, and that is what makes mathematics possible. And mathematics is evidence for design, not superstition.

The interview may never have aired. I tend to flub the gap-tooth creationist moron role, so interviews with me are often not aired.

* I am thinking here of numbers like pi, that just go on and on and never shut up, but you can work with them anyway. (You just decide where you want to cut the mike.)

Uncommon Descent Contest 10 winner declared

by Denyse O'Leary
ARN correspondent

For Uncommon Descent Provide the Code: for Dawkins' WEASEL Program, we have declared a winner - 377 responses later - and it is Oxfordensis:

It seems that Dawkins used two programs, one in his book THE BLIND WATCHMAKER, and one for a video that he did for the BBC (here's the video-run of the program; fast forward to 6:15). After much beating the bushes, we finally heard from someone named "Oxfordensis," who provided the two PASCAL programs below, which we refer to as WEASEL1 (corresponding to Dawkins's book) and WEASEL2 (corresponding to Dawkins's BBC video). These are by far the best candidates we have received to date.
Go here for more.

Note: Apparently, Bill Dembski is taking care of the award.

Reclaiming Biology From The Design Heisters

Review Of The Eighth Chapter Of Signature In The Cell by Stephen Meyer
ISBN: 9780061894206; Imprint: Harper One

By Robert Deyes
ARN Correspondent

In the middle ages, Moses Maimonides debated heavily with Islamic philosophers over the Aristotlean interpretation of the universe. By looking at the stars and seeing their irregular pattern in the heavens, he concluded that only design could have generated the star arrangements he observed (1). In the process he ruled out necessity and the Epicurean ideology of chance. Centuries later Isaac Newton similarly opted for design as the best explanation for the origins of our solar system. Writing in his General Scholium for example Newton left us with no doubt over where his focus lay:

"This most beautiful system of sun, planets, and comets could only proceed from the counsel and dominion of an intelligent and powerful Being" (2).

Still, with the revolutions in thought brought forth by the likes of Pierre Simon Laplace and of course later Charles Darwin, the stage was set for chance and necessity to become the only players permissible in scientific discourse (1). Today science operates under the conviction that the material world "is all there is, and that chance and impersonal natural law alone explain, indeed must explain, its existence" (3).

So, what of chance? When statisticians refer to chance events what they really mean is that the exact combination of physical factors that cause these events are so complex that their occurrence cannot be reasonably predicted. Implicit in an appeal to chance is the negation of any sort of law-like necessity or Maimonidean-style recourse to design. On the flip side, Stephen Meyer reminds us in Signature In The Cell that that chance hypotheses can be eliminated when "a series of events occurs that deviates too greatly from an expected statistical distribution" (p.180).

A casino player winning 100 bets consecutively while spinning a roulette wheel is an obvious example of such a deviation. But low probability in itself is not enough for detecting design. Indeed fundamental to this particular non-chance alternative is the recognition of some sort of discernible pattern- 100 wins on a roulette wheel for example- that compels us to suspect that an intelligence somewhere is directing the outcome.

For Meyer such insights were seeded through conversations he held with philosopher William Dembski in the hallways of academia as he grappled with questions relating to life's origins. Much to the chagrin of the Darwin-faithful, today Dembski not only contends that design, "is a legitimate and fundamental mode of scientific explanation on a par with chance and necessity" but also argues that there exists a set of criteria for reliably detecting design in biology (1).

Pattern discernment, Dembski asseverates, can be retrospectively applied; that is, to events that have already occurred. Indeed as any spy buff will attest, cryptoanalysts routinely decode signals only after these signals have been generated and transmitted. Intelligent involvement in such cases can either be ruled in or out through a thorough examination of the available probabilistic resources (4).

In Signature In The Cell Meyer builds on Dembski's cornerstone case and uses a seemingly non-ending supply of illustrations to firm up his own supportive arguments. But the reader is nevertheless left pondering over what relevance such illustrations have to the matter at hand, namely demonstrating that the origin of life requires more than just chance. Meyer meticulously alleviates such concerns with a component-by-component breakdown of the probabilistic resources of our cosmic landscape. He writes:

"There are a limited number of opportunities for any given event to occur in the entire history of the universe. Dembski was able to calculate this number by simply multiplying the three relevant factors together: the number or elementary particles (1080) times the number of seconds since the big bang (1016) times the number of possible interactions per second (1043). His calculation fixed the total number of events that could have taken place in the observable universe since the origin of the universe at 10130" (pp.216-217).

Applying his calculations on limits to biology Meyer notes:

"the probability of producing a single 150 amino acid protein by chance stands at about 1 in 10164. Thus for each functional sequence of 150 amino acids there are at least 10164 other possible non-functional sequences of the same length...Unfortunately that number vastly exceeds the most optimistic estimate of the probabilistic resources of the entire universe- that is the number of events that have occurred since the beginning of its existence" (p.217).

While such a rationale has already been advanced in the peer-reviewed literature (5), it is as profoundly relevant today as it was in its original context. Those design heisters who acrimoniously steal intelligent design away from the realm of biology do so at a tremendous cost to us all. Intelligent design is after all not 'pie in the sky' story telling. It is rigorous science.

Neuroscience: The importance of focused attention

by Denyse O'Leary
ARN correspondent

In the Huffington Post, Rick Smith (October 9, 2009) notes

In a 2005 article for the United Kingdom's Philosophical Transactions of the Royal Society of London, physicist Henry Stapp and psychiatrist Jeffrey Schwartz showed that sustained concentrated attention on any particular mental experience-a thought, an insight, an image, even a fear-not only kept the brain circuitry involved open and alive but also eventually produced physical changes in the brain's structure. In effect, by increasing attention, you are creating brain architecture specifically suited to the challenges before you. Little wonder, then, that performance should grow dramatically.
Schwartz is the lead author of The Mind and the Brain, which sets forth this thesis in more detail. Basically, our minds become what we focus attention on, and this can be good or bad for us, depending on what that is.

Meanwhile, this Dark Age blog post (October 11 2009) mentions both Mario Beauregard, the third author of the 2005 paper and yours truly as well.

Intelligent Design Legitimized Through Darwin's Own 'Vera Causa' Criterion

Review Of The Seventh Chapter Of Signature In The Cell by Stephen Meyer
ISBN: 9780061894206; ISBN10: 0061894206; Imprint: HarperOne

By Robert Deyes
ARN Correspondent

The distinction between historical and experimental science is one that extends back over the centuries and at its core seems easy to grasp. Whereas historical science has as its focus events that have defined the history both of our planet and larger cosmos, experimental science has its eye on the current operation of nature.

The 19th century philosopher William Whewell coined the term 'palaetiological sciences' to describe those fields of science, such as geology and paleontology, that have a historical perspective (1). Whewell's broad application of the term shone through in his two great works, his History of the Inductive Sciences and his Philosophy of the Inductive Sciences (1). Immanuel Kant used a similar distinction contrasting those sciences that describe "relationships and changes over time" with those that deal with the "empirical study and classification of objects...at present" (2).

As part of their analytical process, scientists routinely assess the validity of competing hypotheses to determine which best explain the data they have at their disposal. The late Cambridge philosopher Peter Lipton formally defined such a process of validation in his book Inference To The Best Explanation (3). Put simply, Lipton considered the best explanation for the occurrence of a natural event as one that obviously best identifies a likely cause. Lipton's formalization rode on the back of 19th century geologist Thomas Chamberlin's 'method of multiple working hypotheses' (4) and provided an improvement over Charles Peirce's abductive reasoning- the process through which an established rule is used to explain a tangible observation (5).

Abductive reasoning would have us say that given a rule such as "If it rains the grass is wet", the occurrence of wet grass must invariably lead to the conclusion that rain had fallen at some moment in the past (5). Nevertheless Peirce was quick to identify an inherent fallacy in such a thread of logic- a fallacy known amongst philosophers as the 'affirmed consequent'. According to one review:

"Affirming the consequent, sometimes called converse error, is a formal fallacy committed by reasoning in the form: If P, then Q. Q. Therefore, P. Arguments of this form are invalid in that [they] do not always give good reason to establish their conclusions, even if their premises are true." (5)

In the above illustration, the fallacy is all too evident since rain is quite obviously not the only causal agent that waters our lawns (summertime sprinklers and hose pipes stand out as self-evident alternatives!). The question that naturally follows is, given numerous causally adequate explanations, how might one go about deciding which supplies the greatest explanatory power?

One way is to resort to vera causa ("causes now in operation") as Darwin did when he used animal migration behaviors to explain common descent. According to Darwin "the simplicity of the view that each species was first produced within a single region captivates the mind. He who rejects it, rejects the vera causa of ordinary generation with subsequent migration, and calls in the agency of a miracle" (6). Darwin of course assumed that the 'now operational' variations observed in animal breeding could likewise explain macro-evolutionary changes throughout the history of life.

An alternative approach to the causal adequacy question is to seek out additional lines of evidence that either prop up or debunk competing explanations. Stephen Meyer expounds on this salient point in the seventh chapter of his most recent book Signature In The Cell,

"the process of determining the best explanation often involves generating a list of possible hypotheses, comparing their known (or theoretically plausible) causal powers against the relevant evidence, looking for additional facts if necessary, and then, like a detective, progressively eliminating potential but inadequate explanations until, finally, one causally adequate explanation for the ensemble of relevant evidence remains" (p.166)

Historical scientists are of course not the only group to employ such a procedural chain. Meyer's impressive list of distinguished professions- including clinical diagnosticians and forensic detectives- that are 'cause-focused' in their modes of operation, gives us much to ponder over. And his follow-on question is brilliantly relevant- might not intelligent design supply the most causally adequate explanation for the origin of biological information? The answer may surprise some. It turns out that by the same 'vera causa' line of reasoning used by Darwin 150 years ago, intelligent causation in biology remains a distinct possibility. After all, a cornerstone claim in the ID offensive is that we routinely observe intelligent agents as 'causes now in operation' that generate the same type of specified information as we find in DNA.

Meyer goes on to boldly entertain the idea that intelligent design presents us with the only causally adequate explanation for the origin of biological information and spends much of the remainder of his book tying together substantial evidence in support of his position. As for Darwin, one can only imagine how he might have felt coming back to find intelligent design legitimized through his very own criterion. My hunch is that he would have applauded the current state of debate.

Identical twins: The differences explored

by Denyse O'Leary
ARN correspondent

We are told (in a Nova program, Ghost in your Genes, October 16, 2007) ,

Scientists have long puzzled over the different fates of identical twins: both have the same genes, yet only one may develop a serious disease like cancer or autism. What's going on? Does something else besides genes determine who we are? In this program, NOVA reveals the clues that have led scientists to a new picture of genetic control and expression. One such clue is the surprisingly modest number of genes that turned up when technology made it possible to map the human genome. The Human Genome Project was originally expected to find at least 100,000 genes defining the human species. Instead the effort yielded only about 20,000 - about the same number as in fish or mice - too few, some believe, to account for human complexity. Learn more about the connection between epigenetics, aging, and cancer on the program's companion website.
"What's going on? Does something else besides genes determine who we are?"

Um, yes. Here are three obvious observations right away:

- All we need to know about any life form is not necessarily in its DNA, as the program makes clear. Frustratingly, the true causes and cures of cancer and autism are controversial and clouded.

But our DNA is not a book of magic in which all the answers are written, and it is too bad if anyone thought it was.

- Identical twins may have almost-identical DNA, but usually one is the dominant twin and the other the sub-dominant one. Also, they tend to separate as adults and have different experiences. Over a lifetime, these differences can add up.

- Also, humans are intelligent and make choices. Different choices lead to different outcomes. The fact that anyone should doubt that this occurs and would be important is a symptom of the damage materialism (= you are either a robot or a monkey) has done to science.

Uncommon Descent Contest 11: Can biotechnology bring back extinct animals?

by Denyse O'Leary
ARN correspondent

This one's a bit of fun, but there is a serious purpose behind it. Go here to enter.

In "A Life of Its Own: Where will synthetic biology lead us?" (September 28, 2009 New Yorker mag), Michael Specter reports, "If the science truly succeeds, it will make it possible to supplant the world created by Darwinian evolution with one created by us."

Jurassic Park, anyone? Consider this:

... researchers have now resurrected the DNA of the Tasmanian tiger, the world’s largest carnivorous marsupial, which has been extinct for more than seventy years. In 2008, scientists from the University of Melbourne and the University of Texas M. D. Anderson Cancer Center, in Houston, extracted DNA from tissue that had been preserved in the Museum Victoria, in Melbourne. They took a fragment of DNA that controlled the production of a collagen gene from the tiger and inserted it into a mouse embryo. The DNA switched on just the right gene, and the embryo began to churn out collagen. That marked the first time that any material from an extinct creature other than a virus has functioned inside a living organism.

It will not be the last. A team from Pennsylvania State University, working with hair samples from two woolly mammoths—one of them sixty thousand years old and the other eighteen thousand—has tentatively figured out how to modify that DNA and place it inside an elephant’s egg. The mammoth could then be brought to term in an elephant mother. "There is little doubt that it would be fun to see a living, breathing woolly mammoth—a shaggy, elephantine creature with long curved tusks who reminds us more of a very large, cuddly stuffed animal than of a T. Rex.," the Times editorialized soon after the discovery was announced. "We're just not sure that it would be all that much fun for the mammoth."

The article discusses both the promise and the peril or reengineering nature.

Personally, I am a bit skeptical that an extinct creature can be resurrected from DNA alone, but ... wait! What I thought was passing traffic turned out to be a herd of tyrannosaurs heading off to eat the McDonalds.

So now to Uncommon Descent Contest Question 11: For a free copy of Stephen Meyer's Signature in the Cell (Harper One, 2009), how likely do you think biotechnologists will be in bringing back the Tasmanian wolf or the woolly mammoth? You can try the tyrannosaur too if you are feeling ambitious.

Here are the contest rules, not an extensive read.

Uncommon Descent Contest Question 12: Can Darwinism beat the odds?

by Denyse O'Leary
ARN correspondent

Here's the latest UD Contest Question, so use this link to enter.

Addressing the Inbox, I discovered this most interesting tale about lotteries in Bulgaria, a tale that reminds me of a similar suspicious lotto in my own Canadian province of Ontario.

In Money Matters, at Australia's news.com, we learn that "Lottery numbers the same in consecutive draws in Bulgaria" (correspondents in Sofia, Agence France-Presse, September 16, 2009)

Here are the bullet points, and you can read the rest yourself.

- The numbers 4, 15, 23, 24, 35, and 42 were drawn two weeks in a row / File
- Same numbers picked in consecutive draws
- Review of the national lottery is ordered
- Probability is 4.2 million to one

Hmmmm. If these charges are true, I'm glad I am not in charge of that investigation. I would hardly want to hear all the lies people would probably try to tell me. Our Ontario premier, faced with a similar situation, fired the chair and the whole board of the lottery corporation and decided to start fixing the problem from scratch. I would recommend looking for statisticians and tough cops, not just anyone with the "power from behind" to sit through an endless board meeting.*

But here's the question that this and other questionable lottery stories leaves me with: The intelligent design theorists emphasize probability issues. Their chief knock against Darwinism is that it appears improbable. In the same way, an accidental origin of the fine-tuned values of our universe appears improbable. If I understand the matter correctly, the universe is assumed to be over 13 billion years old, or so, and Earth over 4 billion years old. (I assume these values for convenience as I believe them to be generally accepted.) So we can assume a basis for computing probability.

So, for a free copy of the Privileged Planet DVD, which addresses the fine tuning of the universe:

Uncommon Descent Contest Question 12: Can Darwinism beat the odds. If not, why not? If so, how?

You might want to look at Bill Dembski's No Free Lunch.

*One alternative: Don't have a lottery at all. Lotteries attract vast moral hazard and corruption because they look like free money. I never supported the idea and don't buy tickets, and think that worthy causes should be funded in the usual ways, through taxes, donations, memberships, sponsorships, premiums, etc. But this mini-editorial is unrelated to the point of the contest question.

Neurolaw: The new "Freudian psychology", but this time with expensive gadgets?

Recently, I noted here and here the growth of "neurolaw," the - in my view often misguided - attempt to apply neuroscience to crime and punishment. I've since had a chance to read the excellent article by Michael S. Pardo and Dennis Patterson, "Philosophical Foundations of Law and Neuroscience", to be published in the University of Illinois Law Review in 2010. It provides an overview and critique of this growing field (and explains why it should shrink instead).

On a personal note, all this reminds me so much of Freudianism. Once upon a time, many years ago during an argument, an amateur Freudian psychologist informed me that my problems - as he perceived them - were due to the fact that I hated my mother.

I had never imagined that. How could I hate my mother and not even know it? Well, he explained, the hatred was in my Unconscious ....

So I solved the problem immediately by just disbelieving in the Freudian Unconscious. I continued to disbelieve and to not hate my mother, so far as I know and my behaviour would suggest, for another 45 years. Of course, it is possible I have a Freudian Unconscious somewhere in which I hate my mother, but it has had no impact on my life.

Today, the same person would announce instead that he had found a "hate Mom circuit" in my hippocampal gyrus, or something.

So no, I don't think neurolaw is any more scientific than Freud's Unconscious. Finding someone's fingerprints - and only his fingerprints, not anyone else's - on the steak knife used to stab another patron in a bar plus a security videocam catching him stabbing that guy, now that's what I mean by "scientific." I don't mind paying taxes for a criminal justice system that deals in that sort of evidence, but I am very skeptical of this "neurolaw" craze.

I've always thought neuroscience should stay as close to medicine as possible. In medicine, as Sir William Osler put it, you cure sometimes, alleviate often, and comfort always. So neuroscience would never be a weapon against anyone; it might help or might not help, in cases of strokes or mental disorders, for example, but the first principle of medicine, as Hippocrates used to say, is "First, do no harm."
