LITTLE ICE AGE; KIERKEGAARD AND FANATICISM; LICHENS ARE A TRINITY; NITRATES, MIGRAINES, AND GUT BACTERIA

THE ICE PALACE

Rivers rang solid as cobbled highways.
Wine froze in glasses.
Birds fell from the sky.
In deadliest winter of oblivious time,
Tzarina Anna commissioned an ice palace.

In the middle of the Neva,
artisans fashioned finest ice
into porticoes and columns,
ice statues set in niches
in the style of an Italian villa. Inside,

the frozen furniture was carved
down to an ice clock and a box of ice snuff.
The walls glimmered a faint blue.
Candelabras floated
as in a thousand mirrors.

In the ice orchard hung crystal rows
of ice oranges, painted orange.
Six ice cannons guarded the gate.
an ice elephant curled its trunk,
a man blowing a trumpet hidden inside.

This luminous fantasy for the sake
of a practical joke: a courtier and his bride
transported in an iron cage
on a live elephant, to spend
their wedding night on a bed of ice —

ice logs in the fireplace,
guards stationed to prevent escape.
The couple survived
by dancing all night,
blue-lipped, slipping and falling.

A winter like that always carried off
the sick and the poor.
To bury the dead you had to thaw
the ground with fire. Thirty thousand
roubles, a Tzarina’s whim. By June

the palace was melted to a few
dirty ice floes drifting in the river.
The architect was in prison,
awaiting execution. The Tzarina ruled
for one more year, amid beheadings

and ballet. Then, like a bad queen
in a fairy tale, she was forgotten.

THE LITTLE ICE AGE
 
Europe’s “Little Ice Age” actually lasted several centuries, from the early 14th century through the early 19th century (the last time the Thames River froze over was in 1804). The early Middle Ages were a warm period; then the weather got much colder. The main theory is decreased solar activity combined with increased volcanic activity.

One interesting theory is that deforestation of Northern Europe resulted in large areas of land becoming agricultural fields; especially when covered with snow, these fields reflect a lot more sunlight, causing a cooling (even now, rural areas are significantly cooler than cities). Increased levels of carbon dioxide in the atmosphere eventually overcame this side effect of agriculture. 

Here is a summary of all the theories of what caused this long-lasting period of cold temperatures called Little Ice Age:

THE LESSONS OF THE “LITTLE ICE AGE”

 
~ “If history is any guide the [recent] “natural” disasters may be just the beginning—at least, that’s the implication of a comprehensive new book by British historian Geoffrey Parker, “Global Crisis: War, Climate Change, and Catastrophe in the Seventeenth Century.” Behind a tumultuous and grueling series of revolutions, wars, and famines, which ultimately killed off a third of the human population, was a culprit, he writes: a period of global cooling known as the Little Ice Age. Extreme weather caused crop failures, which led to hunger, disease, and forced migrations, which in turn translated to political and social chaos. 

 
The idea for “Global Crisis” first occurred to Parker nearly 40 years ago, when he heard a radio interview with solar physicist John A. Eddy, who had discovered that the reign of Louis XIV, from 1643 to 1715, coincided with a unique solar phenomenon: a lack of sunspots. (Scientists believe the lack of sunspots contributed to the Little Ice Age.) Eddy mentioned that this was particularly interesting because during this period “there were some wars, and some revolutions,” Parker recalls. “And I thought, yeah, some! That’s an understatement.”

While the book is set squarely in the 17th century, it’s intended as a cautionary tale. And it also offers a lesson about what seems to have worked: Parker finds that survival often hinged on the willingness of central government to take action, coercively or not. “Here’s the evidence,” Parker says, “that climate really does matter, and we need to prepare.”

Parker, who is the Andreas Dorpalen professor of European History at Ohio State University, spoke to Ideas from his home in Ohio.

IDEAS: You had a sense that there was a connection between climate change and this global crisis. Were you surprised by the extent of what you found?

PARKER: Yes. I was always afraid of drawing bull’s-eyes around bullet holes. That’s to say, you find something in the climatic record and it’s roughly equivalent to the human archive and you say, “Oh, wow, A must have caused B,” but then on closer inspection they don’t line up. But in this case . . . the two sources aligned perfectly. Once you find that, you want to find more.

IDEAS: The book details how rulers in a few areas enacted policies that limited the damage. But some of those measures were brutal and unfair and perhaps only possible in an authoritarian state.

PARKER: I’m going to disagree slightly with the second part, which is that only they could make those decisions. These rulers, particularly the Mughal emperors in India and the Tokugawa shogun in Japan, do indeed take executive action which is brutal, stifles opposition, which requires people to give up their freedoms. But they do, in return, provide protection and food. That option was also open to rulers elsewhere. The Chinese emperors, most of the European monarchs also had those powers; they chose not to use them or they used them to wage war . . . In return for survival, it was necessary to sacrifice liberty.

IDEAS: Can you share an example of how the cooling climate interacted with political and social realities to cause devastation?

PARKER: My favorite example occurs in Ireland on the 23d of October, 1641. There’s an uprising of Irish Catholics, particularly in Ulster, in Northern Ireland. The Catholics rise up against their Protestant neighbors. The Catholics on the whole are tenants, and the Protestants are landowners. And they rise up and they drive them out of their homes....

But the strange thing is, 1641 is the coldest year on record, and snow and ice falls almost immediately. Ireland never has snow in October. And if you read the aftermath of the rebellion, the Protestant survivors overwhelmingly say they’ve survived in spite of the cruel cold. Twice as many of them say those who died died of the cold rather than because a Catholic killed them. So you could say that the Little Ice Age doubled if not more than doubled the casualties.

Why does that matter? Because it’s the scale of the killing that inspires the Protestants for revenge. Eight years later, Oliver Cromwell will arrive in Ireland, he will depopulate the areas with Catholics, send them beyond the Shannon River. There is a huge changeover of land ownership in Ireland that is the root of the problem in Ireland today.

IDEAS: People might read the book and say, “That was then, these things could never happen now.” What do you say to that?

PARKER: Let’s start with last [May], shall we, and the millennial floods in central Europe, for which there was very little preparation, so hundreds of thousands of people lost their homes and a number of people were killed. We could go back to Sandy, to Katrina. Natural catastrophes happen, and some countries prepare for them and some don’t.

We need to protect ourselves, and pay now to avoid paying much more later. If we don’t prepare, we will be like the 17th century. The only difference is that we have the resources to do something and they did not.

IDEAS: It seems making the necessary changes can take a long time. You write about how barriers on the Thames were first proposed after devastating floods in the 1700s, but they weren’t actually funded until 1972.

PARKER: Gradually, those opposed — shipping interests, local governments who said they can’t afford it — were overruled by the central government. It’s the Tokugawa solution. You have to accept a greater view of central government action . . . All over the countries of the world there is a fear of central government. It’s not unjustified. But when it comes to preparing for climate change, only big government has the resources to act in advance. That’s the dilemma we face.

IDEAS: How can history help us in terms of trying to ease resistance to central government actions?

PARKER: History is the best argument for being willing to concede a certain degree of our own autonomy for the greater good. That’s the problem with civil society, isn’t it? Hobbes and Locke both wrote about it in the 17th century, both get enshrined in the Constitution. The reason we have the Bill of Rights, the amendments, is because the Constitution was thought to give too much power to central government. But the more you look at history, the more you realize we’re in a slightly different situation with regard to the climate. The dilemma is, do we pay now to prepare or do we pay a whole lot more later to repair? It’s an individual choice. The decision in the US lies with the states. They have to accept a greater degree of intervention by the federal government.

Oriana: 

We certainly see the Southern states, with their epic floods and tornadoes, and their equally gigantic hatred of the federal government and constant threats to secede (but they never secede when you want them to), also rely most on the federal government when it comes to disaster relief. But the rational solution would be preparation — and only the central government has the resources initiate large-scale projects. I hate to think how severe the disasters will need to get before anything is done.

“Germany has declared war on Russia. Swimming in the afternoon.” ~ Franz Kafka in his diary entry for August 2, 1914

KIERKEGAARD’S REBELLION: PIETY OR FANATICISM?

 
~ “[At twenty-eight], he would cancel his engagement to Regine Olsen to begin a life of celibacy that would also mark the start of his philosophical career: “My engagement to her and the breaking of it,” he wrote, “is really my relationship to God.”

Kierkegaard is widely considered the most important religious thinker of the modern age. This is because he dramatized with special intensity the conflict between religion and secular reason, between private faith and the public world, and he went so far as to entertain the thought that a genuine reconciliation between them is impossible.

Society, for Kierkegaard, is a place of leveling conventions, and the ethical principles that bind us together ignore the genuine self. It is faith alone, uncontaminated by public understanding, that distinguishes the authentic individual, and faith is something wholly interior, a leap into paradox. For Kierkegaard, as for Barth, God remains “wholly other” and cannot be pressed into service for mundane causes.

At their limit such arguments suggest religious absolutism; they extol the believer even if his belief runs against all accepted codes of humanity. In reading Kierkegaard’s works one begins to fear that the individual whom he celebrated as “the knight of faith” too closely resembles that figure upon whom we have heaped so many of the anxieties of our own time: the religious fanatic.


Kierkegaard, a drawing by his cousin Niels Christian Kierkegaard, 1840

But Kierkegaard’s thinking is more subtle than this. A lover of irony, he signed many of his works with pseudonyms: Vigilius Haufniensis (“Watchman of Copenhagen”), Johannes de Silentio, Anti-Climacus, and, perhaps best of all, Hilarius Bookbinder. Everyone in Copenhagen knew that Søren was the author of his works, but this did not deter him from giving his pseudonymous personae a further twist of the pen, at times adding to the title page of a book the scholarly note that it had been “edited by Søren Kierkegaard.”

Daphne Hampson, the author of Kierkegaard: Exposition and Critique, permits herself the unusual gesture of thanking S.K. himself:

    My life would have been subtly different had I not encountered Kierkegaard. He has been a source of delight and edification with his insights and perspicacity. I am moved by his love of God, his sensitivity to others, and his sparkling wit.

But, she adds, Kierkegaard has also helped her to grasp “with greater clarity why I should not wish to be Christian.”

Kierkegaard’s own devotion to his faith was unqualified. Although he was born into financial comfort, his father had arrived as a nearly destitute youth in the Danish metropolis of Copenhagen, and he brought with him a lingering nostalgia for the Moravian pietism that flourished in the Jutland countryside. Søren himself was schooled in the evangelical Lutheran Church of Denmark, but he was racked by doubt about whether its respectable teachings were genuinely Christian. 


The Marxist theoretician Georg Lukács suggested that Kierkegaard’s entire philosophy could be found in his separation from Regine. Either/Or is in fact a meditation on the conflict between two modes of existence, the hedonistic or aesthetic (as described in the “Diary of a Seducer”) and the ethical (in which one awakens to remorse and “holiness”). To the individual who must choose either one life or the other, Kierkegaard says, reason offers no guidance. But at the book’s conclusion we learn that neither path is right, for in prayer alone we find truth: “We gladly confess that in relation to [God] we are always in the wrong.”

ABRAHAM: A ROLE MODEL, OR A REVOLTING BARBARIAN?

In the same year Kierkegaard also published what surely remains his most famous work, Fear and Trembling: A Dialectical Lyric. It is here, hiding behind the pseudonym of “Johannes de Silentio,” that S.K. insists on the stark opposition between public obligation and private faith. The book offers a meditation on the “Akedah,” the biblical episode in which Abraham appears ready to sacrifice his beloved son Isaac in obedience to God’s command and is only prevented from doing so by divine intervention. If this book arouses controversy today it is partly because its author does not flinch from considering the most extreme implications of the biblical tale.

Kierkegaard grants that any reasonable person who wishes to follow social norms must condemn Abraham as a would-be murderer. But we are asked to consider the alternative possibility, that Abraham’s obedience signifies the genuine “paradox” of individual faith without which religion is impossible. From the observer’s point of view this faith must appear preposterous, and we are right to conclude that Abraham’s love of God is “incommensurable with the whole of actuality.”

But for Kierkegaard this is precisely the point: faith entails a paradox by which the individual cannot make himself understood and yet “the particular is higher than the universal.” Abraham embraces the impossible proposition that through sacrifice he will receive his son alive: “Only he who draws the knife gets [back] Isaac,” Kierkegaard wrote. It is commitment, heroic yet absurd, that distinguishes Abraham as a “knight of faith.”

In the nearly endless commentaries on the Akedah some have argued that God never meant for Abraham to go through with the sacrifice. The medieval Jewish commentator Maimonides was especially troubled by the proposal that God “tested” Abraham since this implied that God did not know the outcome of the test—a violation of the principle of divine foreknowledge. For Christians the unrealized sacrifice of Isaac has an important part in Old Testament prophecy since it was thought to prefigure the actual sacrifice of Jesus Christ. For Muslims Abraham’s faith is praiseworthy but they hasten to explain that it was not Isaac who was readied for sacrifice but Ishmael, ancestor to all who worship Allah.

Modern readings of the episode are no less varied. Many have followed Kierkegaard in praising Abraham’s devotion, though few have matched him in analytical intensity. But Hampson is troubled (and rightly so, I think) by a religious disposition that violates our common understandings of humanity. Appealing to feminist criticism, she sees in the God of Kierkegaard a distinctly patriarchal ideal of stern (even violent) authority.

The charge is familiar but it reflects our own cultural preconceptions of male and female conduct. Indeed, the notion that God has gender at all involves an unwarranted lapse into anthropomorphism. The abstract deity of the Protestant West is customarily called “God the Father,” but as a matter of philosophical principle it makes no more sense to imagine God as a conventional man (the strong, silent type) than it does to picture God with the attributes we conventionally assign to women.

More worrisome, in my view, is not Kierkegaard’s lapse into anthropomorphism but rather the opposite: his readiness to amplify the doctrine of Protestant abstraction to a limit where the divine exceeds all understanding. Kierkegaard’s God lies at such a great remove from everyday categories as to contravene our most fundamental and enduring norms of morality. When a parent believes he hears voices that command him to take a knife to his own child our proper response should be not praise for his piety but horror at his self-evident lunacy. Kierkegaard is of course aware that this is our customary belief. But he sees in Abraham’s conduct a “teleological suspension of the ethical,” which is to say, he entertains the thought that religion imposes a higher purpose on us than what ethical reasoning demands.

Here, as Hampson reminds us, Kierkegaard belongs to the tradition called “divine command theory.” God does not command an action because it is good; rather, an action is good only because God commands it. One can admire Kierkegaard for the candor with which he pursues this principle to its perverse conclusion. But it smacks of authoritarianism. If a parent hears such an obscene command we should extol him not if he falls in line but only if he disobeys. Resistance to barbarism, even when it is commanded by the highest of all authorities, is the true mark of the blessed.

 Caravaggio: The Sacrifice of Isaac, 1604

There is a painting called The Sacrifice of Isaac by Caravaggio that hangs in the Uffizi, about which the philosopher J.M. Bernstein has recently written a telling commentary. The look in Isaac’s eyes as Abraham holds the knife to his throat bespeaks not just terror but protest. Though he wishes to be an obliging son, he cannot assent to what his father is determined to do. His resistance is visceral, the cry of a human animal whose desire to live calls into question any ennobling ideas of divine obligation. For Bernstein, the painting is an allegory for the birth of secular consciousness: it expresses a dawning awareness that if faith demands barbarism, then it is faith that must yield. But Kierkegaard’s argument runs in precisely the other direction: when faith and humanity conflict, faith supervenes. He is most blessed who persists in his piety even if he has made himself utterly unintelligible to those around him.

Such arguments run through many of Kierkegaard’s most celebrated works, which ruminate on the chasm between God and humanity, between the individual and the collective.

 At stake, Hamson writes, was a basic question regarding the place of religion in modern society:

    Should there be a broad state church, a spiritual home for the Danish people, which could provide a focus for the nation in times of crisis or rejoicing, able also to offer guidance and comfort to individuals whether or not they normally attended Christian services, a place where they might negotiate life’s transitions. Or by contrast should there be…a “confessing church,” standing for defined and stringent Christian beliefs, based on a certain reading of the New Testament, its members apparently ready…for “martyrdom”?

The question is still with us today, and not only for Christianity but for all faiths that confront a choice between solitude and society, individual purity and the comforts of belonging.

*

But Kierkegaard was an unbending conservative, and the political consequences of his religious absolutism remain uncertain. His hatred of the mob, for instance, fosters a healthy skepticism toward political conformity but also a disabling contempt for the public good. A rather different line of influence connects him to illiberal critics of modern democracy such as Carl Schmitt, the Nazi legal theorist who cited the Dane as an authority when he claimed that the ultimate problems in politics require radical decision, not reasonable deliberation.

There is a deep irony in Kierkegaard’s rebellion. Although he imagined himself a critic of modern convention, his individualist bid to wrest himself free of social constraint was a highly modern ideal. As the philosopher Charles Taylor has explained, in the secular age even those who cleave to a conventional faith conceive of their religion as one option among many: it is something an individual must will to have and no longer something one is merely given as an artifact of collective history. The age of religious reform was but one stage in the historical process that Taylor calls the “disembedding” of the self from shared traditions of meaning.

Ironically, the desire to stand as an authentic individual beyond all such traditions is the greatest conceit of the bourgeois era and Kierkegaard was in this respect far more conformist than he cared to admit. And yet none of us wishes wholly to surrender this desire for authenticity since it is also the very sign of possibility itself, the hope that life might be otherwise than it is. To abandon this hope is to give up on possibility altogether. Against all the forces that counsel resignation Kierkegaard remains not just the knight of faith but something more: the eternal child.” ~

Oriana:

That line between being a devout believer and a religious fanatic is awfully thin . . . When a person is willing to sacrifice the well-being of his family (for instance) for the sake of an all-consuming relationship with an imaginary being, that's where a problem may arise. I’ve read of only one such case — it’s probably quite rare nowadays.

But Kierkegaard seemed to be advocating an uncompromising piety and blind obedience to divine command, a willingness to submit and sacrifice like Abraham. The danger of putting anything above ethics is self-evident. 


 
Tangentially, some suggest that while conventional (mainstream or “liberal”) Christianity is bound to disappear, those who are truly devout will embrace radically strict churches. We will see them as pious when their activities benefit others; if they hurt others or even themselves (e.g. sexual repression and the almost inevitable pathologies that follow), we will call them religious fanatics.

Kieerkegard would no doubt agree with the traditional idea that a saint is not necessarily a good person, but someone who has an intense personal relationship with god. That may have been good enough  in the Middle Ages; if someone spent many hours every day praying, that was saintly. I think now we judge more by the “fruits” of their activity and by the humanistic yardstick of whether a person does something good for others.

Likewise, the idea that the opposite of sin is not virtue but faith appears to be dangerously close to fanaticism. Again, obedience to an imaginary being is be primary, human beings coming second. Of course to a believe this imaginary being is real and allegedly exists “out there” and not just inside the believer’s mind. But to a non-believer, this is delusion. It can be a benign delusion that encourages acts of kindness, or a malignant delusion (oddly enough, there are Christian hate groups; Islam has no monopoly on hate).



KIERKEGAARD: A SKEIN OF QUOTATIONS

~ It will be easy for us once we receive the ball of yarn from Ariadne (love) and then go through all the mazes of the labyrinth (life) and kill the monster. But how many are there who plunge into life (the labyrinth) without taking that precaution? ~

[Oriana: I suspect that by “monster” Kierkegaard means despair. For me personally, one’s vocation is the kind of love that can guide and protect. But the love in the sense of affection that we give and receive also guides and protects.

By the way, it’s not that we “choose” to plunge into the labyrinth of life with or without Ariadne's thread. We are forced to plunge whether or not we have received enough love — or have found our vocation/talents already in childhood, and had the ability to develop those talents and pursue that vocation.]

~ If I were to wish for anything, I should not wish for wealth and power, but for the passionate sense of the potential, for the eye which, ever young and ardent, sees the possible. Pleasure disappoints, possibility never. And what wine is so sparkling, what so fragrant, what so intoxicating as possibility! ~

~ The more one suffers, the more one has a sense for the comic. ~

[Oriana: This reminds me of “Tragedy is for the young, who haven’t experienced yet it for real; only they can afford it.” ~ A. S. Byatt, in a Paris Review interview. Once we’ve lived for a while, we see that life is a mixed-genre play: tragedy and comedy all mixed up. Black humor always seems to surface, always, and does heavy irony.]

~ It belongs to the imperfection of everything human that man can only attain his desire by passing through its opposite. ~

~ The tyrant dies and his rule is over; the martyr dies and his rule begins. ~ [Oriana: This sounds wonderful, but we need only remember suicide bombers to be horrified.]


~ To have faith is to lose your mind and to win God. ~ [note Kierkegaard’s rejection of reason; this is the famous Kierkegaardian “leap of faith”]



About Kierkegaard:


    History has a way of reducing individuals to flat, two-dimensional portraits. it is the enemy of subjectivity, which is why Stephen Dedalus called it "a nightmare from which I am trying to awake". If we think of Kierkegaard, of Nietzsche, of Hölderlin, we see them standing alone, outside of history. They are spotlighted by their intensity, and the background is all darkness.

They intersect history, but are not a part of it. There is something anti-history about such men; they are not subject to time, accident and death, but their intensity is a protest against it. I have elsewhere called such men "Outsiders" because they attempt to stand outside history. which defines humanity on terms of limitation, not of possibility. ~ Colin Wilson in Rasputin and the Fall of the Romanovs, p. 13-14 (1964)

LICHENS ARE A TRINITY 
 
In 1995, if you had told Toby Spribille that he’d eventually overthrow a scientific idea that’s been the stuff of textbooks for 150 years, he would have laughed at you. Back then, his life seemed constrained to a very different path. He was raised in a Montana trailer park, and home-schooled by what he now describes as a “fundamentalist cult.” At a young age, he fell in love with science, but had no way of feeding that love. He longed to break away from his roots and get a proper education.

At 19, he got a job at a local forestry service. Within a few years, he had earned enough to leave home. His meager savings and non-existent grades meant that no American university would take him, so Spribille looked to Europe.

Thanks to his family background, he could speak German, and he had heard that many universities there charged no tuition fees. His missing qualifications were still a problem, but one that the University of Gottingen decided to overlook. “They said that under exceptional circumstances, they could enroll a few people every year without transcripts,” says Spribille. “That was the bottleneck of my life.”

Throughout his undergraduate and postgraduate work, Spribille became an expert on the organisms that had grabbed his attention during his time in the Montana forests—lichens.

In the 150 years since Schwendener, biologists have tried in vain to grow lichens in laboratories. Whenever they artificially united the fungus and the alga, the two partners would never fully recreate their natural structures. It was as if something was missing—and Toby Spribille might have discovered it.

He has shown that largest and most species-rich group of lichens are not alliances between two organisms, as every scientist since Schwendener has claimed. Instead, they’re alliances between three. All this time, a second type of fungus has been hiding in plain view. 

“There’s been over 140 years of microscopy,” says Spribille. “The idea that there’s something so fundamental that people have been missing is stunning.” 

Down a microscope, a lichen looks like a loaf of ciabatta: it has a stiff, dense crust surrounding a spongy, loose interior. The alga is embedded in the thick crust. The familiar ascomycete fungus is there too, but it branches inwards, creating the spongy interior. And the basidiomycetes? They’re in the outermost part of the crust, surrounding the other two partners. “They’re everywhere in that outer layer,” says Spribille.

Despite their seemingly obvious location, it took around five years to find them. They’re embedded in a matrix of sugars, as if someone had plastered over them. To see them, Spribille bought laundry detergent from Wal-Mart and used it to very carefully strip that matrix away.

Unless you know what you’re looking for, there’s no reason why you’d think there are two fungi there, rather than one—which is why no one realized for 150 years. Spribille only worked out what was happening by labeling each of the three partners with different fluorescent molecules, which glowed red, green, and blue respectively. Only then did the trinity become clear.

“The findings overthrow the two-organism paradigm,” says Sarah Watkinson from the University of Oxford. “Textbook definitions of lichens may have to be revised.”

“It makes lichens all the more remarkable,” adds Nick Talbot from the University of Exeter. “We now see that they require two different kinds of fungi and an algal species. If the right combination meet together on a rock or twig, then a lichen will form, and this will result in the large and complex plant-like organisms that we see on trees and rocks very commonly.  The mechanism by which this symbiotic association occurs is completely unknown and remains a real mystery.”

MIGRAINES, NITRATES, AND GUT BACTERIA

Migraine sufferers have a different mix of gut bacteria that could make them more sensitive to certain foods, scientists have found.

The research showed that migraine sufferers had higher levels of bacteria that are known to be involved in processing nitrates, which are typically found in processed meats, leafy vegetables and some wines.

The latest findings raise the possibility that migraines could be triggered when nitrates in food are broken down more efficiently, causing vessels in the brain and scalp to dilate.

When nitrates in food are broken down by bacteria in the mouth and gut they are eventually converted into nitric oxide in the blood stream, a chemical that dilates blood vessels and can aid cardiovascular health by boosting circulation.

However, around four in five cardiac patients who take nitrate-containing drugs for chest pain or heart failure report severe headaches as a side effect.

Dr Brendan Davies, a consultant neurologist at the University Hospitals of North Midlands and a trustee of the Migraine Trust, said the idea of gut bacteria playing a role in migraine was medically plausible. “There’s something called a hot dog headache, where nitrates are suspected to be involved,” he said. “This is interesting work, but would need to be confirmed.”

The study, published on Tuesday in the journal mSystems, sequenced bacteria found in 172 oral samples and 1,996 faecal samples from healthy participants, who had also reported whether they were affected by migraines.

In both oral and fecal samples, people with migraines had slightly higher levels of bacteria linked to breaking down nitrates.

The scientists are now planning a controlled diet study of migraine sufferers to see whether nitric oxide levels in the bloodstream are linked to migraine attacks.

ending on beauty

Yellow and heavy, a last ray of the sun
Congeals in a brilliant dahlia bouquet.
As in a dream I hear a viol
And the thin strains of a clavecin.

~ Anna Akhmatova, “Evening Room,” 1912

Viol and clavecin are historical instruments, invoking past elegance. Even that last ray of the sun “congeals” in a dahlia bouquet. Someone, perhaps a widow, still maintains the room, putting fresh flowers in the vase — but it’s a place of the past, of youth and love long gone. 




Charles:

Ice Palace is a great poem. I like the last stanza the best.

ABRAHAM: A ROLE MODEL, OR A REVOLTING BARBARIAN? Your explanation has more wisdom then the Bible.

I’d rather befriend a person with an 800 credit rating then a person that sits and meditates and “works on himself" all day.

Oriana:

A reminder: My recent blogs contain a lot of excerpts from articles. Please credit the article, and not me, except when it comes to the commentary after the link.

The statement about Caravaggio’s painting is especially perceptive: “The painting is an allegory for the birth of secular consciousness: it expresses a dawning awareness that if faith demands barbarism, then it is faith that must yield.” But then it’s bizarre that Abraham failed to haggle with Yahweh, as he’d done on at least one other occasion: how many just men in Sodom would save the city. The willingness to sacrifice Isaac a nasty instance of blind obedience. We can excuse it only on the grounds that it was the barbarous culture of the time. The same barbarous sacrifice is repeated in the Christian interpretation of the crucifixion — and all note that at that point human sacrifice was no longer practiced in Judaism.

Apologists may say that what matters in the story of Isaac is the last-minute reprieve — a sign that the willingness to sacrifice Isaac was sufficient, but human sacrifice would no longer be required. But it’s precisely that willingness to kill that appalls us and must be condemned. Nor is the problem merely archaic — willingness to kill in the name of religion is still present in the world.

People who meditate for hours on end — I mean those who really put a huge amount of time into it — seem to me just like people who pray for a long time every day (it’s rare now, but I used to see some very devout women in my childhood). It’s an escape from life, from relationships — and even from activities like gardening, which certainly involves the risk of failing, the nastiness of pests and diseases. Life demands coping, meaning action rather than contemplation. I regret every minute spent praying — how lovely it would have been to have spent that time learning Italian!

(Of course some meditation is fine — but the wisdom of “nothing in excess” pertains to religious practices as much as anything else.)

Galileo drawing of sun spots makes me appreciate his genius all the more.
