Robot swarms: scientists work to harness the power of the insect world

Sam Thielman in The Guardian:

ScreenHunter_1375 Sep. 20 17.20As robotics advances, scientists continue to take cues from the natural world, whether it’s by building robots out of material from animals, like cloned rat muscle or jellyfish matter, or building them in imitation of dogs or cats. And now, those scientists are learning to simulate intelligence by imitating a swarm.

“Swarm robotics”, beyond being one of the scariest terms outside of a Terminator film, is the name roboticists give to robots that can coordinate behavior between multiple bodies, acting as a group. Thomas Schmickl of the Artificial Life Laboratory at the University of Graz in Austria, points out that robots as complex as humans or even dogs are a long way off, but the possibility in the insect world for simple animals to behave in ingenious ways as a group can provide some insight into how to simulate intelligence.

Schmickl’s current crop of robots work mostly underwater – his swarm of as many as 20 swimming robots, all named Jeff, imitates a shoal of fish. With the EU-supported Collective Cognitive Robots project, he hopes to develop not just hardware but algorithms and other software to make group behavior smarter.

“[M]onolithic, non-scaling technology is currently hitting the wall everywhere,” Schmickl said. He points out that computers now often have multiple central processing units, and says that swarms are not necessarily armies of robot bugs. “[W]e talk about the ‘internet of things’ – that might also be perceived as another kind of swarm.”

Istanbul and the coming neo-cosmopolitanism

Iason Athanasiadis in Al Jazeera:

2014466445332734_20Two articles that appeared on the same day last month illuminated wildly differing aspects of daily life in contemporary Istanbul. The first appeared in the Turkish newspaper Milliyet titled Beaten, exploited and locked in a room, and described how the police discovered a man, referred to as TM, one of the tens of thousands of Syrian refugees flooding the city, locked up in a textile factory by his Turkish employers in between shifts. When he dared to request a pay-raise, he was beaten.

On the same day, the Wall Street Journal ran a beautifully-photographed feature titled The Discreet Charm of Istanbul, about a Turkish businesswoman, Asli Tunca, and her Belgian husband, Carl Vercauteren, who purchased a 19th century, five-story, 7,000sqr ft building with a garden in Istanbul's posh Beyoglu district and renovated it. The lady of the house called the house Hazz, Ottoman for “Enchantment”. The article concluded with Vercauteren saying that, “If there's a place on earth where God lives, it's Istanbul. The whole city has an energy and rich contrasts.”

After his cruel ordeal, TM would struggle to agree with the first part of Vercauteren's quote, but he might sympathise with his conclusion. TM and the Vercauterens inhabit the same city, yet they live in different worlds. Already an urban behemoth of 14 million, Istanbul continues its vertiginous ascent towards reclaiming its former cosmopolitan status.

Existence as Resistance

Jenny Gathright in Harvard Magazine:

Slavery_frederick-douglass_Corbis-EGuess who was the most photographed American of the nineteenth century.” Fletcher University Professor Henry Louis Gates Jr., director of the Hutchins Center for African and African-American Studies, prepares for the surprise on my face. As it turns out, the answer is Frederick Douglass. Researchers have found at least 160 photographs of Douglass, who praised the medium of photography for enabling him to counter the racial caricatures so frequent in artistic representation of black people at the time. It should not be wholly surprising that one of the most prominent American figures of his era would also be the most photographed—yet black history is often marginalized in the history of the West.

…In his 1861 address at Boston’s Tremont Temple, Frederick Douglass said, “Pictures, like songs, should be left to make [their] own way in the world. All they can reasonably ask of us is that we place them on the wall, in the best light, and for the rest allow them to speak for themselves.” The exhibit (which has minimal text accompanying the photos) seems to heed Douglass’s advice. Mussai wrote me, “The notion of the sitters’ gaze and a sense of agency, dignity, and beauty emanating from the portraits is crucial in the curatorial organization of the exhibition: especially as you sit in the final gallery, surrounded by the different members of the African Choir, each engaging the viewer directly.” To Mussai, the final gallery is a “space of transformative encounters, and a kind of sanctuary to appreciate, reflect, and imagine what their lives might have been like…and what our lives are like today.”

A Strangeness in my Mind

Max Liu in The Independent:

OrhanOrhan Pamuk is becoming that rare author who writes his best books after winning the Nobel Prize for Literature. Whereas many writers, such as Alice Munro and VS Naipaul, received the top honour near the ends of their careers, Pamuk was only 54 when, in 2006, he became Turkey’s first Nobel Laureate. That left him plenty of time to add to his achievements, and his subsequent output, which includes his epic novel The Museum of Innocence (2008), is warmer, funnier and more beautiful than the works that preceded it. And yet I still know a surprising number of readers who find Pamuk’s writing dense and emotionally cold. I read him for the first time on a visit to Istanbul and admit that, at first, I was more enchanted by the city than by the prose. I’m glad I persevered, though, because Pamuk reminds me that the truly rewarding writers aren’t necessarily the ones we like immediately. When I learned three years ago that Pamuk was writing a long novel about 40 years of history, witnessed through the eyes of an Istanbul street vendor, the prospect sounded as delicious as a glass of Turkish tea. Now I’m pleased to report that the results are magnificent. If you haven’t enjoyed Pamuk’s books in the past then A Strangeness in My Mind might well be the one that wins you over.

Like James Joyce, Pamuk holds a looking-glass up to his city. Set between 1969 and 2012, his new novel describes the dizzying period when Istanbul’s population increased from three to 13 million. Weaving his way through this mutating landscape, where old meets new and east meets west, is Mevlut Karata, who, aged 12, migrates with his father from rural Anatolia. Mevlut sells yogurt, rice and boza (“a traditional Asian beverage made of fermented wheat, with a thick consistency, a pleasant aroma, a dark, yellowish colour, and low alcohol content”). He wanders “the poor and neglected cobblestone streets on winter evenings crying ‘Boo-zaa,’ reminding us of centuries past, the good old days that have come and gone.” At his cousin Korkut’s wedding, Mevlut is transfixed by the bride’s sister.

Sunday Poem

Sonnet 15

When I consider every thing that grows
Holds in perfection but a little moment,
That this huge stage presenteth nought but shows
Whereon the stars in secret influence comment;
When I perceive that men as plants increase,
Cheered and checked even by the self-same sky,
Vaunt in their youthful sap, at height decrease,
And wear their brave state out of memory;
Then the conceit of this inconstant stay
Sets you most rich in youth before my sight,
Where wasteful Time debateth with decay
To change your day of youth to sullied night,
And all in war with Time for love of you,
As he takes from you, I engraft you new.

Interview: George Saunders and Ben Marcus

George Saunders and Ben Marcus in Granta:

ScreenHunter_1373 Sep. 19 20.39Since his first book appeared in 1995, Ben Marcus has been an essential, radical and incendiary presence in American letters. What distinguishes his work is the way it uses a sacred awe for language to seek the emotionally resonant new. The effect on a reader (this one, anyway) is to rejuvenate one’s relation to language – which is to say, one’s relation to life. In addition to writing short story collections (The Age of Wire and String, and Leaving the Sea), a novella (The Father Costume) and novels (Notable American Women and The Flame Alphabet), Marcus is an important editor and anthologist. His 2004 anthology, The Anchor Book of New American Short Stories, has now been followed with New American Stories, published this year by Vintage in the US and Granta Books in the UK. These anthologies are essential, important, and often controversial – Marcus is as original, thoughtful, and passionate an anthologist as he is a writer – a radical chooser, we might say. I had a chance to talk with Ben about the anthology and the ways that compiling it has affected his views on the short story, and on American culture.

George Saunders: I thought your introduction to the anthology was so good – should be required reading for any workshop of young short-story writers. One of the things I admired about it is how succinctly you stated an essential and, I think, undervalued idea: that the primary storytelling goal is magic, achieved by mysterious means – that what we do isn’t ultimately an analytical or linear thing. And that its goal is . . . delight. You describe wrapping your young son up in a blanket and giving him a wild ride around the house and the pleasure he takes in this game: ‘he is asking to be amazed and afraid in this situation we’ve contrived’ – a perfect description of why we read fiction, and also a description that is very useful for writers – sort of freeing, to be given a charge like that (‘Go forth and delight!’). So I guess what I wanted to ask was: Did you always feel this way about fiction? That it is a sort of experiential machine, designed to do something to us? If not, how did you used to feel about it, and how did your current understanding of it evolve?

How Wasps Use Viruses to Genetically Engineer Caterpillars

Ed Yong in The Atlantic:

Lead_960This is a story about viruses that became domesticated by parasitic wasps, which use them as biological weapons for corrupting the bodies of caterpillars, which in turn can steal the viral genes and incorporate them into their own genomes, where they protect the caterpillars from yet more viruses. Evolution, you have outdone yourself with this one.

The wasps in question are called braconids. There are more than 17,000 known species, and they're all parasites. The females lay their eggs in the bodies of still-living caterpillars, which their grubs then devour alive.

As early as 1967, scientists realised that the wasps were also injecting the caterpillars with some kind of small particle, alongside their eggs. It took almost a decade to realise that those particles were viruses, which have since become known as bracoviruses. Each species of braconid wasp has its own specific bracovirus, but they all do the same thing: They suppress the caterpillar’s immune system and tweak its metabolism to favour the growing wasp. Without these viral allies, the wasp grubs would be killed by their host bodies.

So, the viruses are essential for the wasps—but the reverse is also true. Unlike most other kinds of virus, these bracoviruses cannot make copies of themselves. They are only manufactured in the ovaries of the wasps, and once they get into the caterpillars, their life cycle ends. Some might say they’re not true viruses are all. They're almost like secretions of the wasp’s body.

Margo Jefferson’s ‘Negroland: A Memoir’

20SMITH-blog427Tracy K. Smith at the New York Times:

In her new memoir, Margo Jefferson, a former critic at The New York Times, chronicles a lifetime as a member of Chicago’s black elite, a world she celebrates and problematizes by christening it (and her book) Negroland. “Negroland,” she writes, “is my name for a small region of Negro America where residents were sheltered by a certain amount of privilege and plenty. Children in Negroland were warned that few Negroes enjoyed privilege or plenty and that most whites would be glad to see them returned to indigence, deference and subservience. Children there were taught that most other Negroes ought to be emulating us when too many of them (out of envy or ignorance) went on behaving in ways that encouraged racial prejudice.”

That warning — that manner of instilling in children the understanding that with privilege comes responsibility — strikes me as the true impetus for Jefferson’s book. For once we become accustomed to delicious glimpses of Negroland’s impeccable manners and outfits, the meticulously orchestrated social opportunities and fastidiously maintained hairstyles, what we begin to notice is the cost and weight of this heavy collective burden.

Jefferson’s memoir pushes against the boundaries of its own genre. Yes, it begins with a scene from the author’s childhood. And yes, we learn about Jefferson’s older sister, Denise, and their parents: a father who was the longtime head of pediatrics at Provident, once the nation’s oldest black hospital; and a mother who was an impeccably dressed socialite. But it quickly swerves into social history; a good 30 pages of the book’s opening are dedicated to defining and chronicling the rise of America’s black upper class.

Patrick Modiano’s many detours into echoes, longings and tension

La-ca-jc-patrick-modiano-20150920-001David L. Ulin at the LA Times:

Patrick Modiano opens his most recent novel, “So You Don't Get Lost in the Neighborhood,” with an epigraph from Stendhal: “I cannot provide the reality of events, I can only convey their shadow.” It's an almost perfect evocation of the book, not to mention Modiano's career.

The French writer, who won the Nobel Prize last year for a body of work as deft and beautiful as any in postwar European literature, is an excavator of memory — not only his own or those of his characters (many of whom bear, as J.D. Salinger once observed of his fictional alter ego Seymour Glass, “a striking resemblance to — alley oop, I'm afraid — myself”), but also that of Paris.

That's why his fiction resonates so deeply; it occupies an elusive middle ground between place and personality. At its center is the legacy of the German occupation, which Modiano, who was born in 1945, refers to in his memoir “Pedigree” as “the soil — or the dung — from which I emerged.” What he's suggesting is that history is both personal and collective, that identity is dependent, at least in part, on circumstance. This can refer to family — Modiano's mother, an actress, met his father, a black marketeer, in the morally blank landscape of Vichy Paris — but it also has to do with how the past appears to rise up from the streets around us, mingling with the present until we are no longer sure where (or when) we are.

an intensely personal history of porcelain

Af847877-1357-4422-8afa-f1b34066a19dAN Wilson at the Financial Times:

In The White Road, de Waal turns his attention to porcelain — from its Chinese origins to Meissen, Wedgwood and the present day — and to humanity’s obsession with producing whiter than white ceramics. As with the earlier book, this becomes a scorchingly personal story. Every stage in the material’s history becomes a pilgrimage, as de Waal follows in the footsteps of the potters and travellers who discovered the clay and stone that porcelain is made of, and celebrates the beautiful objects that humanity has fashioned from this ingenious conjunction.

Readers who had only heard of, but not read, The Hare with Amber Eyes might have wondered what was so interesting about how a collection of little bibelots moved from pillar to post; those who had read the book could reply that what made it a page-turner was de Waal’s skill at explaining human passion as it survives in objects. Likewise the new book is no dry history of old pots. It is a story about — well, about skills and artistry, certainly, and about politics too. It is also a disquisition on whiteness, and its different meanings. “I’ve read Moby-Dick,” de Waal writes. “So I know the dangers of white. I think I know the dangers of an obsession with white, the pull towards something so pure, so total in its immersive possibility that you are transfigured, changed, feel you can start again.”

It’s OK to Be a Luddite

David Auerbach in Slate:

LudditeTechnology will save us! Technology sucks! Where today’s techno-utopians cheer, our modern-day Luddites, from survivalists to iPhone skeptics to that couple that dresses in Victorian clothing and winds its own clock, grumble. Understanding the former urge is pretty easy: It’s a fantasy of a perfect world. The Luddite impulse, however, isn’t so clear—and we shouldn’t automatically dismiss it as one that scapegoats technology for society’s ills or pines for a simpler past free of irritating gadgets. Rather, today’s Luddites are scared that technology will reveal that humans are no different from technology—that it will eliminate what it means to be human. And frankly, I don’t blame them. Humanity has had such a particular and privileged conception of itself for so long that altering it, as technology must inevitably do, will indeed change the very nature of who we are. To understand the appeal of being a Luddite, you need only read these words of Leon Trotsky:

To produce a new, “improved version” of man—that is the future task of Communism. Man must see himself as a raw material, or at best as a semi-manufactured product, and say: “At last, my dear homo sapiens, I will work on you.”

This vision, promptly disposed of by Stalin, is so intuitively unappealing that even with the return of authoritarianism to Russia, neither Vladimir Putin nor any of his associates have revived the idea of scientifically perfecting man. Such language brings back bad memories of eugenics, Nazi experiments, Tuskegee, and worse. Yet those fears don’t stop us from using technology to become those new, improved versions of ourselves—from buying up iPads and smartphones and storing the digital residue of our lives in the cloud.

The Rationality of Rage

Matthew Hutson in The New York Times:

AngerANGER is a primal and destructive emotion, disrupting rational discourse and inflaming illogical passions — or so it often seems. Then again, anger also has its upsides. Expressing anger, for example, is known to be a useful tool in negotiations. Indeed, in the past few years, researchers have been learning more about when and how to deploy anger productively. Consider a forthcoming paper in the November issue of the Journal of Experimental Social Psychology. Researchers tested the effectiveness of expressing anger in three types of negotiations: those that are chiefly cooperative (say, starting a business with a partner), chiefly competitive (dissolving a shared business) or balanced between the two (selling a business to a buyer). In two experiments, negotiators made greater concessions to those who expressed anger — but only in balanced situations. When cooperating, hostility seems inappropriate, and when competing, additional heat only flares tempers. But in between, anger appears to send a strategically useful signal.

What does that signal communicate? According to a 2009 paper in Proceedings of the National Academy of Sciences, anger evolved to help us express that we feel undervalued. Showing anger signals to others that if we don’t get our due, we’ll exert harm or withhold benefits. As they anticipated, the researchers found that strong men and attractive women — those who have historically had the most leverage in threatening harm and conferring benefits, respectively — were most prone to anger. The usefulness of anger in extracting better treatment from others seems to be something we all implicitly understand.

Saturday Poem

Motion
.
You're crying here, but they're dancing,
there they're dancing in your tear.
There they're happy, making merry,
they don't know a blessed thing.
Almost the glimmering of mirrors.
Almost candles flickering.
Nearly staircases and hallways.
Gestures, lace cuffs, so it seems.
Hydrogen, oxygen, those rascals.
Chlorine, sodium, a pair of rogues.
The fop nitrogen parading
up and down, around, about
beneath the vault, inside the dome.
Your crying's music to their ears.
Yes, eine kleine Nachtmusik.
Who are you, lovely masquerader.

The trouble with putting too much weight in a bioethicist’s opinion

Sally Satel in Pacific Standard:

MTMzMDI3NDI2NjY5MjA1OTgyLast month, Steven Pinker, cognitive psychologist and public intellectual, argued in a Boston Globe op-ed that bioethicists—those who weigh the ethical implications of biological research—had a moral imperative to “get out of the way” of research. Pinker's assertion was nothing short of a live grenade lobbed into the field of bioethics. While perhaps harsh, there is a sizable kernel of truth in his case.

“A truly ethical bioethics,” Pinker wrote, “should not bog down research in red tape, moratoria, or threats of prosecution based on nebulous but sweeping principles such as 'dignity,' 'sacredness,' or 'social justice.' Nor should it thwart research that has likely benefits now or in the near future by sowing panic [about] Nazi atrocities, armies of cloned Hitlers, or people selling their eyeballs on eBay.” We must not succumb, in other words, to science-fiction scenarios that have little likelihood of materializing.

Pinker's disquisition was spurred by calls for a moratorium on research involving a new technology called CRISPR, a revolutionary gene editing method that is cheap, quick, and easy to use. With the ability to modify small segments of the DNA of eggs and sperm or of the embryo itself—the so-called germ line—scientists hope to eventually use CRISPR to cure certain genetic diseases, by replacing the genes that cause them. But some bioethicists fear that the technology will work too well, thus raising the specter of “eugenics.” Such research, they claim, is “contrary to human dignity” because “the human germ line should be treated as sacred.”
