The Origin of Life

From The American Scientist:

Soup As the frontiers of knowledge have advanced, scientists have resolved one creation question after another. We now have a pretty good understanding of the origin of the Sun and the Earth, and cosmologists can take us to within a fraction of a second of the beginning of the universe itself. We know how life, once it began, was able to proliferate and diversify until it filled (and in many cases created) every niche on the planet. Yet one of the most obvious big questions—how did life arise from inorganic matter?—remains a great unknown.

Our progress on this question has been impeded by a formidable cognitive barrier. Because we perceive a deep gap when we think about the difference between inorganic matter and life, we feel that nature must have made a big leap to cross that gap. This point of view has led to searches for ways large and complex molecules could have formed early in Earth’s history, a daunting task. The essential problem is that in modern living systems, chemical reactions in cells are mediated by protein catalysts called enzymes. The information encoded in the nucleic acids DNA and RNA is required to make the proteins; yet the proteins are required to make the nucleic acids. Furthermore, both proteins and nucleic acids are large molecules consisting of strings of small component molecules whose synthesis is supervised by proteins and nucleic acids. We have two chickens, two eggs, and no answer to the old problem of which came first.

Thursday Poem

the times
Lucille Clifton

it is hard to remain human on a day
when birds perch weeping
in the trees and the squirrel eyes
do not look away but the dog ones do
in pity.
another child has killed a child
and i catch myself relieved that they are
white and i might understand except
that i am tired of understanding.
if this
alphabet could speak its own tongue
it would be all symbol surely;
the cat would hunch across the long table
and that would mean time is catching up,
and the spindle fish would run to ground
and that would mean the end is coming
and the grains of dust would gather themselves
along the streets and spell out:

these too are your children this too is your child

With a wave of the hand

From Scientific American:

With-a-wave-of-the-hand_1 Go into any busy coffee shop and you are likely to see people engrossed in conversation, waving their hands around. A man at the counter describes the coffee he wants to buy – in a mug, not a to-go cup – and his hand takes a familiar shape, as if he were already holding the cozy mug. Nearby, two sisters laugh, as one tells a story about a trip to the barrier reef and all of the fish that she saw, her hands wiggling and darting in an invisible sea in front of her. The drive to gesture when speaking is fundamental to human nature.

If you have thought about why we gesture you probably assumed that we gesture to help others understand what we are saying. Pretending to hold a ceramic mug can help the barista understand exactly which mug you want. Showing how the fish darted to and fro can help your sister get a more vivid picture of what the reef looked like to you. But might gesture also serve another purpose? Many scientists now think that gestures can help the person making them — that moving your hands can help you think. Researchers have become increasingly interested in the connection between the body and thought – in the ways that our physical body shapes abstract mental processes. Gesture is at the center of this discussion. Now the debate is moving into learning, with new research on how students learn to solve math problems in the classroom.

Taliban-Style Justice Stirs Growing Anger

Pamela Constable in the Washington Post:

ScreenHunter_01 May. 21 10.09 When black-turbaned Taliban fighters demanded in January that Islamic sharia law be imposed in Pakistan's Swat Valley, few alarm bells went off in this Muslim nation of about 170 million.

Sharia, after all, is the legal framework that guides the lives of all Muslims.

Officials said people in Swat were fed up with the slow and corrupt state courts, scholars said the sharia system would bring swift justice, and commentators said critics in the West had no right to interfere.

Today, with hundreds of thousands of people fleeing Swat and Pakistani troops launching an offensive to drive out the Taliban forces, the pendulum of public opinion has swung dramatically. The threat of “Talibanization” is being denounced in Parliament and on opinion pages, and the original defenders of an agreement that authorized sharia in Swat are in sheepish retreat.

Math and the City

Steven Strogatz in the New York Times:

Portrait_strogatz_240x270 One of the pleasures of looking at the world through mathematical eyes is that you can see certain patterns that would otherwise be hidden. This week’s column is about one such pattern. It’s a beautiful law of collective organization that links urban studies to zoology. It reveals Manhattan and a mouse to be variations on a single structural theme.

The mathematics of cities was launched in 1949 when George Zipf, a linguist working at Harvard, reported a striking regularity in the size distribution of cities. He noticed that if you tabulate the biggest cities in a given country and rank them according to their populations, the largest city is always about twice as big as the second largest, and three times as big as the third largest, and so on. In other words, the population of a city is, to a good approximation, inversely proportional to its rank. Why this should be true, no one knows.

Even more amazingly, Zipf’s law has apparently held for at least 100 years. Given the different social conditions from country to country, the different patterns of migration a century ago and many other variables that you’d think would make a difference, the generality of Zipf’s law is astonishing.

153 of the newly-elected MPs in India have criminal cases pending against them

From the BBC:

_45795815_election_226afp “There are now 153 MPs with criminal charges and 74 of them with serious criminal charges,” Association for Democratic Reforms (ADR) and National Election Watch, a civil society alliance working for clean politics and accountable governance, said in a press release.

The study said the opposition BJP has most MPs with pending criminal cases at 43 – out of which 19 MPs have serious criminal cases against them.

The Congress party has 41 MPs with criminal cases – out of which 12 MPs have serious charges against them, it added.

The study said a comparison of top 10 MPs with criminal records in 2004 and 2009 elections indicated that number of candidates with very serious criminal backgrounds had declined.

“Several heavy weight candidates with a criminal background have been rejected by voters. In fact, top five MPs with criminal cases from the 2004 Lok Sabha (lower house of parliament) have been rejected by voters.”

But, what remains worrying is that many of the MPs are charged with serious criminal offences, including murder and gang war.

a coarser sieve

Howard Hughes, whose acumen outside certain areas of expertise (aeronautics and the acquisition of beautiful actresses) was rarely sound, once said something intelligent about the relative merits of two movie directors. The remark was delivered in early 1939, when George Cukor had been shooting “Gone with the Wind” for about three weeks. An adaptation of Margaret Mitchell’s thousand-page blockbuster novel, from 1936, about the Old South, the Civil War, and Reconstruction, the movie was the largest and most expensive production in Hollywood up to that time, with a huge cast, massive sets (the city of Atlanta was burned down and then rebuilt), and hundreds of unshaven and bandaged extras trudging across the landscape. As half of Hollywood maliciously cheered, the production slipped into disaster. The script could be kindly described as a mess, and the star—Clark Gable—was in turmoil. The initial rushes displeased David O. Selznick, the legendary, manic producer who dominated every aspect of the film, and he suddenly fired Cukor, who, he later said, couldn’t have handled the more spectacular elements of the movie. In Cukor’s place, Selznick hired Victor Fleming, who was then directing the other big picture in town, “The Wizard of Oz.” Fleming was a vigorous and resourceful man, but few people considered him an artist. The change pleased Gable but distressed the two female leads—the young stage and film actress Vivien Leigh, just arrived from England and not yet a star, and Olivia de Havilland, who was then Howard Hughes’s girlfriend. Both women depended on Cukor, who was known as a “woman’s director,” and de Havilland brought her troubles to Hughes, who advised: “Don’t worry, everything is going to be all right—with George and Victor, it’s the same talent, only Victor’s is strained through a coarser sieve.”

a curmudgeon speaks

41dP8UcYKFL._SL500_AA240_

The street I have lived on for seventeen years is suddenly alive with children. It is quite a delightful place to be nowadays. When I moved here, I don’t believe there was a child on the block apart from my own, who were there only in the summers and on holidays. Now there must be dozens of them, most not yet of school age. Last Halloween, I noticed how many of my neighbors who are young parents accompanied their little ones on their trick-or-treating rounds while themselves dressed up as witches or pirates. I take it this is a manifestation of the “parenting” craze. A word that didn’t exist when I was a young parent—still less when I was the child of young parents—is now used to describe that mode of child-rearing that begins with the reform of the adult to be more child-like rather than, as in generations past, the child to be more adult-like. Mom and dad now involve themselves in their children’s pastimes out of a supposed duty of empathy that is somehow continuous with responsibility for their children’s safety and well-being. I’m sure that there is much that is good about the new parenting, and it must be rather thrilling for the children, at least in their early years. Yet I can’t but see a disquieting connection to the infantilization of the popular culture and the phenomenon of the “kidult” or “adultescent” who dresses in t-shirts and shorts, slurps up fast food, watches superhero movies, and plays video games well into his thirties or even forties. It’s true that there have been for more than a century certain protected areas of childish innocence where Santa Claus or the Tooth Fairy or whatnot have been suffered to remain undisturbed, for a time, by adult consciousness. But this demesne has expanded to include much new territory—like Harry Potter and Batman, who provided so many of the costume themes for Halloween last year—and to encroach on ever more of what once would be considered adulthood. Mom and dad must be intimately involved in their children’s fantasy world not only out of duty to the children but because it is, increasingly, their world too.

A half-century ago, the researchers William Masters and Virginia Johnson brought sex into the laboratory. For thousands of years, sex had been the object of philosophical inquiry and religious stricture, occupying everyone from shamans to psychoanalysts, and giving the world an oceanic supply of marital and extramarital strife. But it hadn’t really been studied, not in the clinical, moment-by-moment manner that Masters proposed. The problem, believed Masters, a stern ob-gyn at Washington University in St. Louis, was that you couldn’t study sex solely by asking people about it, because they were so often unaware of – or dishonest about – what was going on in their own bodies. Along with Johnson, an assistant who soon rose to the rank of co-researcher, Masters brought people, singly and in pairs, into examining rooms and observed them closely with the tools and technologies of modern medicine as they passed into and out of sexual arousal.

Wednesday Poem

Balance
Adam Zagajewski

I watched the arctic landscape from above

and thought of nothing, lovely nothing.

I observed white canopies of clouds, vast

expanses where no wolf tracks could be found.

I thought about you and about the emptiness

that can promise one thing only: plenitude—

and that a certain sort of snowy wasteland

bursts from a surfeit of happiness.

As we drew closer to our landing,

the vulnerable earth emerged among the clouds,

comic gardens forgotten by their owners,

pale grass plagued by winter and the wind.

I put my book down and for an instant felt

a perfect balance between waking and dreams.

But when the plane touched concrete, then

assiduously circled the airport's labryinth,

I once again knew nothing. The darkness

of daily wanderings resumed, the day's sweet darkness,

the darkness of the voice that counts and measures,

remembers and forgets.

The evolutionary argument for Dr. Seuss

From Salon:

Story Why do human beings spend so much time telling each other invented stories, untruths that everybody involved knows to be untrue? People in all societies do this, and do it a lot, from grandmothers spinning fairy tales at the hearthside to TV show runners marshaling roomfuls of overpaid Harvard grads to concoct the weekly adventures of crime fighters and castaways. The obvious answer to this question — because it's fun — is enough for many of us. But given the persuasive power of a good story, its ability to seduce us away from the facts of a situation or to make us care more about a fictional world like Middle-earth than we do about a real place like, oh, say, Turkmenistan, means that some ambitious thinkers will always be trying to figure out how and why stories work.

The latest and most intriguing effort to understand fiction is often called Darwinian literary criticism, although Brian Boyd, an English professor at the University of Auckland in New Zealand and the author of “On the Origin of Stories,” a new book offering an overview and defense of the field, prefers the term “evocriticism.” As Boyd points out, the process of natural selection is supposed to gradually weed out any traits in a species that don't contribute to its survival and its ability to pass on its genes to offspring who will do the same. The ability to use stories to communicate accurate information about the real world has some obvious usefulness in this department, but what possible need could be served by made-up yarns about impossible things like talking animals and flying carpets?

Boyd's explanation, heavily ballasted with citations from studies and treatises on neuroscience, cognitive theory and evolutionary biology, boils down to two general points. First, fiction — like all art — is a form of play, the enjoyable means by which we practice and hone certain abilities likely to come in handy in more serious situations. When kittens pounce on and wrestle with their litter mates, they're developing skills that will help them hunt, even though as far as they're concerned they're just larking around. Second, when we create and share stories with each other, we build and reinforce the cooperative bonds within groups of people (families, tribes, towns, nations), making those groups more cohesive and in time allowing human beings to lord it over the rest of creation.

Darkness and light

From The Guardian:

The-Dark-Side-of-Love-by--002 Syria, more than most, is a land of stories and storytellers. The farmers and shopkeepers describe early Islamic battles or episodes from the Crusades as if they'd attended them in person. A gathering of friends is quickly elevated into a group performance of jokes, laments, myths and conspiracies. Even Syrian surnames suggest stories: there are families called The-Milk's-Boiled, Sip-The-Yoghurt and Undone-Belt. “The deeper you swim into our stories,” a village rhetorician once told me, “the more you understand that they have no floor.”

Yet Syria is better known for its poets, and its TV dramas, than for its novelists. Egypt, with its unending metropolis, is the home of the Arabic novel, and Egypt produced the Arabs' master of fiction, Naguib Mahfouz. But a flame equally bright now burns from Damascus, via Germany, as shown by what may turn out to be the first Great Syrian Novel.

In The Dark Side of Love, Rafik Schami exploits all the resources of the classic realist novel and then goes a little further, forging a new form out of Syrian orality. His basic unit is not chapter or paragraph, but story; a thousand bejewelled anecdotes and tales are buried here, ready to spring, but each is melded with such dazzling surety into the whole that reading the book is always compulsive. In its final, self-exposing passage, Schami compares his method to mosaic work, in which every shiny object is a beauty in itself, yet which in combination, at a distance, reveals a still greater beauty. The novel is even Tolstoyan in its marrying of the personal, social and political spheres, of private with national life.

The Death of Black Nationalist Culture?

A video and audio of a discussion by Ta-Nehisi Coates, Baz Dreisinger, Peniel E. Joseph & Victor Laval over at NYPL Live:

With an African-American president in the White House—and the first black chairman voted to head the Republican National Committee—has black nationalism become irrelevant? Novelist Victor LaValle explores the personal and political valences of the nationalist idea, and makes a case for embracing a more ecumenical view of black experience—including the freedom to move beyond traditional conceptions of blackness. Baz Dreisinger, author of Near Black: White to Black Passing in American Culture; Peniel E. Joseph, author of Waiting 'Til the Midnight Hour: A Narrative History of Black Power in America; and Atlantic Monthly contributing editor Ta-Nehisi Coates respond.

Sri Lanka: After war, Justice

SLLuther Uthayakumaran in openDemocracy:

The long war in Sri Lanka is, it seems, finally at an end. But for many Sri Lankans, even those who have longed for this day – and for whom the last few weeks have been especially intense – it has not ended in the way that we would have wanted. The prolonged siege in the northeast pocket, the shelling, the further loss of life, the vanquishing of the enemy – all this means that the conclusion of this twenty-six-year war is likely to be defined in terms of military victory alone, with no reference to a political solution and the return of democracy. This too is a tragedy.

There is a great responsibility now to make sure that Sri Lanka's future is not defined by the way the war has ended – and that the questions of democracy, justice and accountability are addressed fully in its aftermath. This article is a modest first contribution to that agenda.

There are many ways to view the terrible conflict that has sundered the island since 1983. When the war turned in the 1990s-2000s into a binary battle between the Sri Lankan state and the Liberation Tigers of Tamil Eelam (LTTE / Tamil Tigers), it was ever clearer that for both sides thought and acted solely in terms of the aspirations of states, nationalisms and counter-nationalisms; and that in consequence they regarded the lives of civilians were becoming less and less important. Some of us responded by seeking to establish a position that placed the rights of the individual citizen at the centre of concern.

The Ambivalence Artist

Ambivalenceartist 130 90David Marcus in Dissent:

J.M. COETZEE made an early career out of ambivalence. Restrained and impersonal, he mined the caverns of despair from the safe distance of allegory and literary appropriation. Life and Times of Michael K, his 1983 Booker Prize winner, tracked the itinerant life of a slow-witted gardener in the sparse prose of Kafka. Foe, a work of revisionist and feminist genius, challenged the rugged masculinity of Defoe’s Robinson Crusoe by inhabiting the voice of an imagined female companion. Master of Petersburg occupied not only the melancholic timbre of a Dostoevsky novel—it was, after all, about the great master—but also the stilted Victorian English of a Constance Garnett translation.

Over the past decade, however, Coetzee has adopted an increasingly direct and confessional style. Once dedicated to ectomorphic reticence, he has now allowed himself the fattier tissues of biography. Beginning with his second Booker Prize winner, the 1997 Disgrace, he has spoken through a series of half-selves. Reclusive and dissatisfied, the protagonists of Disgrace, Elizabeth Costello, and Slow Man laid bare the moral and psychological crises of a midlife colonial: shame and guilt foremost, but also the persistent anxieties of physical and sexual decline.

At first glance, Diary of a Bad Year, Coetzee’s most recent entry, seems to follow this “late” tendency toward novelized autobiography. A book of journal entries, it maps the tortuous cartography of Coetzeean doubt through a near biographical stand-in: the eponymous John C, author of Waiting for the Barbarians and recent émigré from South Africa to Australia (a migration Coetzee himself made in 2002).

The End of American Capitalism?

Mark Blyth over at eJournal USA at america.gov:

If you draw what statisticians call a time series of the returns to the U.S. banking sector from 1947 to 2008, it is possible to talk with some confidence about the average rate of profitability of the sector over time, the peaks (1990s to mid-2000s), the troughs (1947 to 1967), and the sharp growth of the sector’s profitability over the past 10 years. If you then add in the data for the period between August 2008 and April 2009, the entire series, like the banking system it describes, simply blows up. Averages, means, variances, and the like dissolve, so extreme have been recent events. Indeed, when the former chairman of the U.S. Federal Reserve Bank, Alan Greenspan, admits that his understanding of market processes was deeply flawed, and when the current chairman, Ben Bernanke, says that we face the greatest crisis since the Great Depression, we should probably take it seriously.

And serious it is. With a grossly diminished $1.3 trillion in assets and as much as $3.6 trillion in liabilities, coupled with a halving of the stock market, the U.S. financial system is either severely stressed, insolvent, or, worse still according to some, at the end of its tether. The end of capitalism has been declared many times before. And yet, to paraphrase American writer and humorist Mark Twain, reports of its death have been greatly exaggerated.

Tuesday Poem

Ashes
Karin Gottshall

You were carried here by hands
and now the wind has you, gritty
as incense, dark sparkles borne

in the shape of blowing,
this great atmospheric bloom,
spinning under the bridge and expanding—

shape of wind and its pattern
of shattering. Having sloughed off
the urn's temporary shape,

there is another of you now—
tell me which to speak to:
the one you were, or are, the one who waited

in the ashes for this scattering, or the one
now added to the already haunted woods,
the woods that sigh and shift their leaves—

where your mystery billows, then breathes.

The Captive Mind

Christopher Hitchens in The Atlantic Monthly:

Edward-upward-wide Early in the 1930s, when he was managing the Hogarth Press for Leonard and Virginia Woolf and preparing the anthology—New Signatures—that would be received as a species of generational manifesto, John Lehmann wrote that he had

heard with the tremor of excitement that an entomologist feels at the news of an unknown butterfly sighted in the depths of the forest, that behind Auden and Spender and Isherwood stood the even more legendary figure of … Edward Upward.

In that reference to the literary-political celebrities of the ’30s, Upward received his due. In a once-famous attempt to get the whole set into one portmanteau term, which was Roy Campbell’s coinage of MacSpaunday to comprehend the names of Louis MacNeice, Stephen Spender, W. H. Auden, and Cecil Day-Lewis, Upward was omitted altogether (as was his friend and closest collaborator, Christopher Isherwood). On the eve of Valentine’s Day this year, at the age of 105, the last British author to have been born in the Edwardian epoch died. If Upward is not better known than perhaps he ought to be, it is probably because he helped instill the Communist faith in his more notorious friends, and then not only outlived them and their various apostasies but continued to practice a version of that faith himself. (For purposes of comparison, MacNeice died in 1963, Day-Lewis in 1972, Auden in 1973, Isherwood in 1986, and Spender in 1995, so with Upward’s death, the last link to that era is truly snapped.)

Message in What We Buy, but Nobody’s Listening

From The New York Times:

John Why does a diploma from Harvard cost $100,000 more than a similar piece of paper from City College? Why might a BMW cost $25,000 more than a Subaru WRX with equally fast acceleration? Why do “sophisticated” consumers demand 16-gigabyte iPhones and “fair trade” coffee from Starbucks? If you ask market researchers or advertising executives, you might hear about the difference between “rational” and “emotional” buying decisions, or about products falling into categories like “hedonic” or “utilitarian” or “positional.” But Geoffrey Miller, an evolutionary psychologist at the University of New Mexico, says that even the slickest minds on Madison Avenue are still in the prescientific dark ages.

Instead of running focus groups and spinning theories, he says, marketers could learn more by administering scientifically calibrated tests of intelligence and personality traits. If marketers (or their customers) understood biologists’ new calculations about animals’ “costly signaling,” Dr. Miller says, they’d see that Harvard diplomas and iPhones send the same kind of signal as the ornate tail of a peacock.
