Tumour mutations harnessed to build cancer vaccine

Heidi Ledford in Nature:

TumorCancer is a genetic disease, driven by mutations that lift the brakes on cell proliferation. But the mutated proteins produced by cancerous cells can serve as a siren call to immune cells, signalling the presence of a cell that has become, in a sense, ‘foreign’. Unfortunately, many of these calls are never heard. Some tumours suppress nearby immune responses, and mutated tumour proteins may not be expressed at high enough levels to rally immune cells. Researchers have long dreamed of using those mutated proteins to generate a vaccine, says immunologist Beatriz Carreno of Washington University in St. Louis, Missouri, but lacked the technological wherewithal to do so.

The advent of cancer-genome sequencing and an improved understanding of the immune system have converged to make that approach possible. Last year, two groups2, 3 showed that such vaccines can work in mice. Carreno and her colleagues have now taken the approach into humans. The researchers sequenced the tumour genomes in samples taken from three people with melanoma and catalogued the mutated proteins in each sample. They then chose seven protein fragments per patient for use in the vaccine. White blood cells were taken from each patient and cultured in the laboratory to generate immune cells called dendritic cells. These cells were then exposed to the protein fragments, allowed to mature in the laboratory and then infused into the patients. By then, the dendritic cells had taken up the protein fragments, and were able to present them to immune cells in the body. The result: immune cells trained to target the mutated proteins produced by the tumour1. Such immune cells were evident in the patients' blood two weeks after vaccination.

Wednesday Poem

At a Happiness Symposium in Wales
.

A psychologist said
Graveyards may help you feel happier,
visit a graveyard when you are depressed

There is a thin line between life and death, my friend
and I am a graveyard

I am happy to be alive, my friend
After Halabja and Anfal
I am happy to become the voice
of a land
that contains the mass graves of our brothers

There is a thin line between life and death, my friend
There is a thin line between life and death

Sven Birkerts Interviews Sven Birkerts

Sven Birkerts in the Los Angeles Review of Books:

There-Is-Simply-Too-Much-to-Think-About-243x366SVEN BIRKERTS: Why did you decide to write about Bellow’s essays in the form of a self-interview? Isn’t that displacing the focus just a bit?

SVEN BIRKERTS: Maybe so, yes. But the idea came to me as a kind of default after I had been beating my head against the standard, familiar thing — you know: hook, overview, bits of excerpt, some wrangling, some praise, followed by the larger pronouncement … I felt I just could not do it one more time. Then I remembered that Bellow had conducted a self-interview (included in this very collection) and something clicked. The form offers certain advantages, the main one being that you can break against the prescribed structure and meander to the things that are more interesting, as happens in good conversation.

But what about fulfilling your reviewer’s responsibility?

I own that there is a certain shirking of the task going on. Which would normally be unconscionable. But this seemed an exception. And here’s my reasoning: first, there’s no need to be arguing for Bellow’s literary status — he is one of our confirmed greats, a Nobelist, admired by his fellow writers the world over. The essays in this book have been published and published again; not only in their original journals like Partisan Review, The Atlantic Monthly, The American Scholar, and The New Yorker, but in previous books. They’ve been reviewed and discussed and —

It sounds like you’re saying “what’s the point?”

I guess I am. On the other hand, there’s always a point in writing about a great writer. That’s what being a great writer means — that he or she can (and ought to) always be written about. Which leads me around to my other rationale for these proceedings: reading the essays had me dropping in on some of the novels — and as I did, my brain started getting revved up in the unique way that it does when I get near that side of Bellow, as if there reallyis simply too much to think about. (I was, it seemed, living out the feeling of the title of the collection.) I was being overrun — like in those old movies when the attacking multitudes finally put their crude ladders up against the castle walls and swarm over everything. (Well, that’s a bit dramatic …)

How Europeans evolved white skin

Ann Gibbons in Science:

Sn-europeansH_0Most of us think of Europe as the ancestral home of white people. But a new study shows that pale skin, as well as other traits such as tallness and the ability to digest milk as adults, arrived in most of the continent relatively recently. The work, presented here last week at the 84th annual meeting of the American Association of Physical Anthropologists, offers dramatic evidence of recent evolution in Europe and shows that most modern Europeans don’t look much like those of 8000 years ago.

The origins of Europeans have come into sharp focus in the past year as researchers have sequenced the genomes of ancient populations, rather than only a few individuals. By comparing key parts of the DNA across the genomes of 83 ancient individuals from archaeological sites throughout Europe, the international team of researchers reported earlier this year that Europeans today are a mix of the blending of at least three ancient populations of hunter-gatherers and farmers who moved into Europe in separate migrations over the past 8000 years. The study revealed that a massive migration of Yamnaya herders from the steppes north of the Black Sea may have brought Indo-European languages to Europe about 4500 years ago.

Now, a new study from the same team drills down further into that remarkable data to search for genes that were under strong natural selection—including traits so favorable that they spread rapidly throughout Europe in the past 8000 years. By comparing the ancient European genomes with those of recent ones from the 1000 Genomes Project, population geneticist Iain Mathieson, a postdoc in the Harvard University lab of population geneticist David Reich, found five genes associated with changes in diet and skin pigmentation that underwent strong natural selection.

the legacy of The New republic

Suter-Columns-ScialabbaGeorge Scialabba at The Baffler:

“Twentieth-century liberalism has won.” So ran the first sentence of The New Republic’s eightieth-anniversary anthology back in 1994. Liberalism “inspired democratic revolutions from the Soviet Union to South Africa,” according to the anthology’s editor, Dorothy Wickenden, and finally “disabused this country of its prolonged infatuation with conservatism.” Occupying the White House were two men with “intellectual edge and moral intuition,” the magazine’s editors enthused, who offered “the best chance in a generation to bring reform and renewal to a country that desperately needs both.”

How accurate you think this judgment is depends on what you understand by that perennially disputed word, “liberalism.” Originally it meant the opposite of mercantilism, the close government regulation of commercial policy to benefit domestic merchants by means of tariffs and restrictions on the movement of capital and technology. Mercantilism, protectionism, and industrial policy all name various aspects of the impulse to limit competition from abroad. As Britain and the United States became the world’s leading economic powers in the nineteenth and twentieth centuries, respectively, each decided that other countries’ efforts to favor the home team were no longer cricket and that unregulated (i.e., “free”) competition—which, by the merest coincidence, they were most likely to win—was in everyone’s best interest. “Liberalism,” from the Latin word for “free,” is the name of this ideology. Even now, European political parties that call themselves “liberal” mean by it “pro-business.” The leading voice of nineteenth-century liberalism was The Economist, which famously argued that to provide famine aid to Ireland would be to interfere with the necessarily benign workings of the free market.

Is ISIS Islamic? Why it matters for the study of Islam

Faqih_and_studentsAnver Emon at The Immanent Frame:

For instance, suppose instead of asking whether ISIS is Islamic, we were to say that ISIS is as much Islamic as it is a product of broken promises at the end of the British and French mandates; ISIS is as much Islamic as it is a product of the American interventions in Iraq; ISIS’s brutality is as Islamic as the Ku Klux Klan’s lynching of Black Americans was Christian, both Islam and Christianity having been used to justify violent brutality. To baldly pose these claims is to reveal the parochialisms that frame debates on Islam and Muslims, that inform certain politics of belonging and difference (read, Fox News), and that bolster the state policies that flow therefrom (e.g. Shari’a legislative bans).

To reveal these parochialisms illuminates how the arguments for and against moral panic artificially reduce the debate on ISIS to an unhelpful zero-sum game of Islamic/unIslamic. The label of “Islam(ic)” in the case of ISIS might be better appreciated as what James Scott in Domination and the Arts of Resistance would call a “hidden transcript” that is now made public. Scott writes about how the oppressed hew to “public transcripts” that might appear as their contented resignation to the status quo. But when they are able to avoid detection, the dominated employ “hidden transcripts” (like dragging one’s feet) to quietly subvert that same status quo.

But what happens when the dominated no longer want their hidden transcript to remain hidden?

The Master Writer of the City

Malcolm_2-042315_jpg_600x763_q85Janet Malcolm at The New York Review of Books:

Images that “stand for something” recur throughout Mitchell’s writing and reinforce the sense that we are reading a single metaphoric work about the city. That the author was a southerner only heightens its authority. As Robert Frank’s European sensibility permitted him to see things as he traveled around America that had been invisible to the rest of us, so Mitchell’s outsiderness gave him his own X-ray vision.

Thomas Kunkel’s biography adds some telling details to what Mitchell’s readers already know about his childhood as the eldest son of a prosperous cotton and tobacco grower in North Carolina.* Perhaps the most striking of these is Mitchell’s trouble with arithmetic—he couldn’t add, subtract, or multiply to save his soul—to which handicap we may owe the fact that he became a writer rather than a farmer. As Mitchell recalled late in life:

You know you have to be extremely good at arithmetic. You have to be able to figure, as my father said, to deal with cotton futures, and to buy cotton. You’re in competition with a group of men who will cut your throat at any moment, if they can see the value of a bale of cotton closer than you. I couldn’t do it, so I had to leave.

Mitchell studied at the University of North Carolina without graduating and came to New York in 1929, at the age of twenty-one. Kunkel traces the young exile’s rapid rise from copy boy on the New York World to reporter on the Herald Tribune and feature writer on The World Telegram.

The Jim Crow Soft-Shoe Segregationists of St. George

Tom Gogola in The Baffler (via Bookforum):

Located Imagein the suburban settlement of St. George, the Mall of Louisiana—and most particularly, the millions in tax revenue it generates—was, until recently, ground zero in a fiercely pitched battle over the economic, political, and racial makeup of Baton Rouge, Louisiana’s capital city. This May, the Baton Rouge city council voted to annex the mall firmly within the city’s borders—thus claiming for the majority-black city one of the key economic prizes that had been in the sights of a new cohort of affluent (and mostly white) would-be municipal secessionists. But that setback for the region’s secessionist forces is unlikely to slow the momentum of their movement, which thrives on a powerful compound of free-market development stratagems, movement-conservative swagger, and new-millennial racial animus…

Throughout the South, rich municipalities have begun to raise the specter of secession—despite the associations that carry over from the last big push by a privileged white Southern elite to carve out a brave new civic destiny for itself, during the years 1861 to 1865. Similar movements to inaugurate breakaway townships and school districts have lately taken off in Georgia, Tennessee, and Alabama.

But the St. George effort is different. For starters, it furnishes a detailed case study in how the unvarnished rhetoric of white reaction has been repackaged as a sunny faith in the mystical healing powers of school choice. And it has drawn a corps of politically prominent supporters who are long-standing entrepreneurs of far-right reaction.

How the subconscious mind shapes creative writing

Charlotte Seager in The Guardian:

BrainDo you remember those plastic slide puzzles you used to get in party bags? They were made up of a three by three grid with eight tiles and a blank square – the missing tile allowing you to move the others around. This nine-grid puzzle was the central image behind the story of Mark Haddon’s The Red House – although, bizarrely, he didn’t know it when he wrote the book. “I was being interviewed by Claire Armitstead at the Edinburgh Books Festival when she said that when she read the book she kept thinking about those tile puzzles,” wrote Haddon on his blog after the interview.

“I felt a lurch, because before writing The Red House I’d given up on a novel called The Missing Square, the central image of which was one of those tile puzzles, and whose organising conceit was that certain absences may make a world imperfect, but they enable that world to change and generate new meanings. I suddenly realised this image had remained a model for the central structure of The Red House, which is a story about the eight remaining members of a family and a ninth member – a stillborn daughter – who is still having a profound effect on the family despite, or because of, her absence.” This hidden structure enabled Haddon to plot and plan his novel around a central theme without even realising it. Unusual, but perhaps not unheard of, this got me thinking: how many other novelists have plotted their books subconsciously? Perhaps another subconscious plotter is John Boyne, who wrote the first draft of The Boy in the Striped Pyjamas in just three days and is known for writing without planning. I caught up with him to see how much of his writing he puts down to hidden thoughts.

The Mind of Those Who Kill, and Kill Themselves

Erica Goode in The New York Times:

AndreHe was described, in the immediate aftermath of the Germanwings crash, as a cheerful and careful pilot, a young man who had dreamed of flying since boyhood. But in the days since, it has seemed increasingly clear that Andreas Lubitz, 27, the plane’s co-pilot, was something far more sinister: the perpetrator of one of the worst mass murder-suicides in history.If what researchers have learned about such crimes is any indication, this notoriety may have been just what Mr. Lubitz wanted. The actions now attributed to Mr. Lubitz — taking 149 unsuspecting people with him to a horrifying death — seem in some ways unfathomable, and his full motives may never be fully understood. But studies over the last decades have begun to piece together characteristics that many who carry out such violence seem to share, among them a towering narcissism, a strong sense of grievance and a desire for infamy.

…Serious mental illness, studies of mass killers suggest, is a prime driver in a minority of cases — about 20 percent, according to estimates by several experts. Far more common are distortions of personality — excesses of rage, paranoia, grandiosity, thirst for vengeance or pathological narcissism and callousness. “The typical personality attribute in mass murderers is one of paranoid traits plus massive disgruntlement,” said Dr. Michael Stone, a forensic psychiatrist in New York who recently completed a study of 228 mass killers, many of whom also killed themselves. “They want to die, but to bring many others down with them, whether co-workers, bosses, family members or just plain folk who are in the vicinity.” Mr. Lubitz, Dr. Stone noted, now ranks among the deadliest of mass killers, in a league with Adilson Marcelino Alves, who in 1961 killed as many as 500 people in a circus fire in Brazil, or Timothy McVeigh, the Oklahoma City bomber, who killed 168 people and injured more than 680 others.

Tuesday Poem

My Tongue Softens on the Other Name
.

In my mother’s backyard washing snaps
above chillies and wild rosemary.
Kapokbos, cottonwool bush, my tongue softens
on the rosemary’s other name.
Brinjal, red peppers and paw-paw grow
in the narrow channel between
the kitchen and the wall that divides
our house from the Severos. At the edge
of the grass by the bedrooms, a witolyf reaches
ecstatically for the power lines.

In a corner in the lee of the house,
nothing grows.
Sound falls here.
Early in the day shadows wash
over old tiles stacked
against the cement wall.
In the cold and silence
my brother is making a garden.

He clears gravel from the soil
and lays it against the back wall.
Bright spokes of pincushion proteas puncture a rockery.
For hours he scrapes into a large stone a hollow to catch
water from a tap that has dripped all my life.
Around it, botterblom slowly reddens the grey sand.
A fence made of reed filters
the wind between the wall and the house.
Ice-daisies dip their tufted heads
toward its shadows.

At night, on an upturned paint tin, he sits
in the presence of growing things.
Light wells over the rim of the stone basin
and collects itself into the moon.
Everything is finding its place.

In V.S. Naipaul’s writing on Conrad, we see who he truly is

Morgan Meis in The Smart Set:

Naipaulvs01In a typical brain-spasm of deep insight, James Wood once wrote that V.S. Naipaul “is a writer who has a conservative vision but radical eyesight.” This, in an essay for The New Yorker a few years ago. The World Is What It Is: The Authorized Biography of V. S. Naipaul by Patrick French had just come out. The literary world was agog. Naipaul, never shy to air controversial opinions or disreputable thoughts, had given his biographer total access to his private life. This created some surprises. One surprise was a revelation about Naipaul’s affair with an Argentinian woman in the early 1970s. Here’s how George Packer described the episode in his review of the biography for The New York Times.

Naipaul and Margaret began an affair that set free all of his desires and fantasies. When his editor and friend Diana Athill scolded him, he replied, “I am having carnal pleasure for the first time in my life, are you saying I must give it up?” Carnal pleasure meant violence — in fact it was inextricable from beating Margaret up, degrading her in bed, turning the great man’s penis into an object of worship. How do we know these things? Because Naipaul tells them to his authorized biographer. “I was very violent with her for two days with my hand; my hand began to hurt. . . . She didn’t mind it at all. She thought of it in terms of my passion for her. Her face was bad. She couldn’t appear really in public. My hand was swollen. I was utterly helpless. I have enormous sympathy for people who do strange things out of passion.”

Reading French’s biography, some praised Naipaul’s honesty. Others felt disgust. It has always been so with Naipaul. He splits opinions, drives a wedge into what might otherwise be polite literary conversations. Nearly everyone who has read Naipaul has strong feelings about him. No side ever fully wins the debate. The Naipaul Question has been a live one for more than forty years.

The trolley and the psychopath

Sally Adee in The Last Word on Nothing:

Shutterstock_159768710-475x317Stop me if you’ve heard this one. A trolley carrying five school children is headed for a cliff. You happen to be standing at the switch, and you could save their lives by diverting the trolley to another track. But there he is – an innocent fat man, picking daisies on that second track, oblivious to the rolling thunder (potentially) hurtling his way. Divert the trolley, and you save the kids and kill a person. Do nothing, and you have killed no one but five children are dead. Which is the greater moral good?

This kind of thought experiment is known as a sacrificial dilemma, and it’s useful for teaching college freshmen about moral philosophy. What you maybe shouldn’t do is ask a guy on the street to answer these questions in an fMRI machine, and then use his answers to draw grand conclusions about the neurophysiological correlates of moral reasoning. But that’s exactly what some neuroscientists are doing. The trouble is, their growing body of research is built on a philosophical house of cards: sacrificial dilemmas are turning out to be exactly the opposite of what we thought they were. Guy Kahane wants to divert this trolley before it drives off a cliff.

Kahane, deputy director of Oxford’s Uehiro Centre for Practical Ethics, has never been a big fan of the sacrificial dilemma. The main problem, he says, is that it has been misapplied to situations it was never intended for.

Physicists engage in a strange debate about whether time really passes

Sean Carroll in Smithsonian Magazine:

ScreenHunter_1121 Apr. 05 18.32When Albert Einstein’s good friend Michele Besso died in 1955, just a few weeks before Einstein’s own death, Einstein wrote a letter to Besso’s family in which he put forward a scientist’s consolation: “This is not important. For us who are convinced physicists, the distinction between past, present, and future is only an illusion, however persistent.”

The idea that time is an illusion is an old one, predating any Times Square ball drop or champagne celebrations. It reaches back to the days of Heraclitus and Parmenides, pre-Socratic thinkers who are staples of introductory philosophy courses. Heraclitus argued that the primary feature of the universe is that it is always changing. Parmenides, foreshadowing Einstein, countered by suggesting that there was no such thing as change. Put into modern language, Parmenides believed the universe is the set of all moments at once. The entire history of the universe simply is.

Today we would call this the “eternalist” or “block universe” view—thinking of space and time together as a single four-dimensional collection of events, rather than a three-dimensional world that evolves over time. Besides Parmenides and Einstein, this picture is shared by the Tralfamadorians, an alien race who appear in Kurt Vonnegut’s novel Slaughterhouse-Five. To a being from Tralfamadore, visiting the past is no harder than walking down the street.

This “timeless” view of the universe goes against our usual thinking. We perceive our lives as unfolding. But it has adherents even in contemporary physics. The laws of nature, as we currently understand them, treat all moments as equally real. No one is picked out as special; the laws simply say how any moment relates to the previous one and to the next.

What Did Jesus Do? Reading and unreading the Gospels

Adam Gopnik in The New Yorker:

Jesus

Verhoeven, citing Crossan, offers an opening scene for a Jesus bio-pic which neatly underlines this point. He imagines a man being nailed to a cross, cries of agony, two companion crosses in view, and then we crane out to see two hundred crosses and two hundred victims: we are at the beginning of the story, the mass execution of Jewish rebels in 4 B.C., not the end. This was the Roman death waiting for rebels from the outset, and Jesus knew it. Jesus’ cry of desolation—“My God, my God, why have you forsaken me?”—though primly edited out or explained as an apropos quotation from the Psalms by later evangelists, pierces us even now from the pages of Mark, across all the centuries and Church comforts. The shock and pity of failure still resonates.

One thing, at least, the cry assures: the Jesus faith begins with a failure of faith. His father let him down, and the promise wasn’t kept. “Some who are standing here will not taste death before they see the kingdom of God,” Jesus announced; but none of them did. Jesus, and Paul following him, says unambiguously that whatever is coming is coming soon—that the end is very, very near. It wasn’t, and the whole of what follows is built on an apology for what went wrong. The seemingly modern waiver, “Well, I know he said that, but he didn’t really mean it quite the way it sounded,” is built right into the foundation of the cult. The sublime symbolic turn—or the retreat to metaphor, if you prefer—begins with the first words of the faith. If the Kingdom of God proved elusive, he must have meant that the Kingdom of God was inside, or outside, or above, or yet to come, anything other than what the words seem so plainly to have meant.

The Executioner We Can’t Live Without: special molecules that kill rotten proteins

Pamela Weintraub in Nautilus:

AaronLast summer, as I interviewed Aaron Ciechanover, who won a Nobel Prize in Chemistry in 2004, his country was at war. Three Israeli boys had just been murdered in the West Bank by Palestinians, then a Palestinian boy had been burned to death in retribution by Israelis. While we sat in his lab at the Technion-Israel Institute of Technology in Haifa, to the north of the bombs, missiles were flying over Jerusalem and Tel Aviv, and a Gaza invasion loomed. The mounting conflict troubled but didn’t ruffle Ciechanover, one of Israel’s greatest scientists and statesmen, who patiently and colorfully explained to me one of biology’s most remarkable processes, how a molecular Pac-Man races through our bodies and devours damaged proteins.For over 40 years, Ciechanover has worked to understand these molecular machines, called shredders. Built around a core molecule called ubiquitin, shredders destroy ruined proteins so that our bodies can replace them with fresh parts and not, says Ciechanover, rot like a side of meat, “brownish-greenish and stinking,” in the sun. Ciechanover shared the Nobel Prize with Avram Hershko, his mentor at Technion, and Irwin Rose, a biochemist at the University of California, Irvine. Scientists already understood the genetic code, how genes coded for the creation of proteins. But the shredder helped control the overall process: the degradation of damaged goods, DNA repair, cell division, and immune defense. The shredder enabled biologists to see the wizard behind the screen.

In your Nobel notes, you said that you learned “to become a long books author rather than a short story writer.” What do you mean?

Science is changing, so I don’t blame the current scientists for being short-range thinkers. But I’m a risk taker. I am an adventurist. I was in medicine and I decided that I don’t want to do it. I took a big risk, but I thought that I should go after my gut feeling and after excitement and after what I really want to do. I’m not in science in order to publish. I’m in science in order to be excited by the discovery. In order to do that, you need to be a marathon runner. Mother Nature doesn’t make itself available to us easily. You need to be patient. You need to take a long risk. You need to be in the business for many years. You need to run slowly but fast—slowly in terms of patience, but fast in order to be competitive. It looks contradictory, but it’s not contradictory. And you really want to dig deep into it. You don’t want to scrape the surface and then move to another one and to another one and to another one. People ask me, “OK, so 40 years you work on ubiquitin, what’s next?” I say, “The next 20 years, if I should still survive them, will be devoted to the same very woman.” Because we are still scratching her surface. That’s the beauty of nature. You dig and dig and dig. You’ll never come to an end.

A General Feeling of Disorder

Oliver Sacks in the New York Review of Books:

Sacks_1-042315_jpg_600x631_q85Nothing is more crucial to the survival and independence of organisms—be they elephants or protozoa—than the maintenance of a constant internal environment. Claude Bernard, the great French physiologist, said everything on this matter when, in the 1850s, he wrote, “La fixité du milieu intérieur est la condition de la vie libre.” Maintaining such constancy is called homeostasis. The basics of homeostasis are relatively simple but miraculously efficient at the cellular level, where ion pumps in cell membranes allow the chemical interior of cells to remain constant, whatever the vicissitudes of the external environment. More complex monitoring systems are demanded when it comes to ensuring homeostasis in multicellular organisms—animals, and human beings, in particular.

Homeostatic regulation is accomplished by the development of special nerve cells and nerve nets (plexuses) scattered throughout our bodies, as well as by direct chemical means (hormones, etc.). These scattered nerve cells and plexuses become organized into a system or confederation that is largely autonomous in its functioning; hence its name, the autonomic nervous system (ANS). The ANS was only recognized and explored in the early part of the twentieth century, whereas many of the functions of the central nervous system (CNS), especially the brain, had already been mapped in detail in the nineteenth century. This is something of a paradox, for the autonomic nervous system evolved long before the central nervous system.
