Secrets of ant rafts revealed

Emma Marris in Nature:

AntsTo negotiate floods and cross streams, fire ants band together — literally — linking together to form rafts and bridges in a feat of social cooperation and biophysics. Now, engineers have made a close study1 of the ants' architectural technique, pointing the way towards new approaches for robot designers and materials scientists. To understand the properties of the ant structures, David Hu, a mechanical engineer at the Georgia Institute of Technology in Atlanta, sought to observe not just the surface of the ant clumps but the structure and joints underneath. First, Hu and his team collected ant colonies — shovelling them, dirt and all, into buckets. After separating out the ants from the dirt, they then put 100 or so ants into a cup and swirled, causing the ants to form into a ball (no water necessary — they come together almost like dough). The researchers then froze the ball with liquid nitrogen so they could examine it in a micro-computed-tomography scanner to come up with a 3-D picture.

But the heat of the scanner melted the ball into a heap of dead ants. After months of experimenting with techniques to keep it together, lead author Paul Foster, now at the University of Michigan, found an unlikely source of inspiration in crack cocaine — specifically, in a method of vaporizing the drug to inhale it. “We did the same process — not with crack, but glue,” says Hu, adding that the authors decided against calling it the ‘crack-pipe method’ in their paper. The researchers heated the glue in an aluminium pot over a flame, with the frozen ant ball suspended on mesh above. The glue vapour rose and lightly coated the ants.Hu and his team found that the ants had grabbed hold of one another with adhesive pads on their legs, which they stretched out to create pockets of air. They also tended to orient themselves perpendicularly to one another, distributing their weight and creating a light, buoyant structure. The formation seems to take advantage of the ants’ different sizes, with smaller ants slotting neatly in between larger ones to add more connections. Each ant averaged 14 connections to fellow ants.

Tuesday Poem

i like my body when it is with your

i like my body when it is with your

body. It is so quite new a thing.

Muscles better and nerves more.

i like your body. i like what it does,

i like its hows. i like to feel the spine

of your body and its bones,and the trembling

-firm-smooth ness and which i will

again and again and again

kiss, i like kissing this and that of you,

i like, slowly stroking the, shocking fuzz

of your electric fur, and what-is-it comes

over parting flesh….And eyes big love-crumbs,

and possibly i like the thrill

of under me you so quite new
.

The Iraq Delusion Revisited

by Ahmed Humayun

ScreenHunter_692 Jun. 16 11.01The conquest of Mosul, Iraq's second largest city, by the Islamic State of Iraq and Syria (ISIS) is the latest indication of the Arab world's descent into chaos. Described by Western officials as even more extreme than Al Qaeda, this formidable Sunni extremist army controls chunks of Syria and is marching on Baghdad, intending to establish an Islamist state that will redraw the boundaries of the Middle East. The rise of ISIS is merely the latest development that underscores yet again the tragic folly of the U.S. invasion of Iraq in 2003.

Americans lost interest in Iraq long before the last American soldier departed the country in December 2011. It is remarkable that after having occupied Iraq for almost a decade, how easy it has been to let the entire experience simply recede into the background. (This amnesia applies even in the case of Afghanistan where American forces are still present in significant number. There is a palpable lack of interest with what is to become of that country and South Asia after the imminent U.S. withdrawal). It seems that when banners of victory cannot be credibly hoisted atop aircraft carriers ala ‘Mission Accomplished', then the story simply isn't worth following anymore.

We must reject this amnesia. We must remember what our leaders did in Iraq and follow this story all the way to its sordid denouement, if only because though the United States can leave, the inhabitants of these countries cannot. We should harbor no illusions that the nightmare that began on September 11, when Al Qaeda's henchmen attacked the United States, is over simply because we are in the process of disengaging from Muslim countries. We must understand our contribution to the festering of this problem so that we may instead contribute to its resolution.

Poem

MOTHER WRITES
TO THE LION OF KASHMIR
SHEIKH MOHAMMED ABDULLAH

They tell me
you are buried
on the banks of Naseem
near the Hazratbal shrine,
your tomb heavily guarded
by India’s army.

I tell them
this represents
one of those ironies
history keeps throwing up:
the very people who jailed
you now guard your tomb

And the very people
whose ‘Lion’ you were
are disenchanted
with you for selling out
to your paymasters in Delhi
who now also bankroll

your son and his son,
sexually-transmitted dynasts,
who dare not even sigh
while soldiers shielded by
the Syrupy Secularism Act
silence the Vale of Saints.

Philosophy is a Bunch of Empty Ideas: Interview with Peter Unger

by Grace Boey

41Has1Vo4HLPhilosophy: you either get it or you don't. The field has its passionate defenders, but according to its critics, philosophy is irrelevant, unproductive, and right at the height of the ivory towers. And now, the philosophy-bashing camp can count a proud defector from the other side: Peter Unger, Professor of Philosophy at New York University, has come out against the field in his latest book, Empty Ideas: A Critique of Analytic Philosophy.

Unger has written extensively over the course of his career on various philosophical topics, and his best-known writings include Ignorance: A Case for Scepticism (1975) and Living High and Letting Die: Our Illusion of Innocence (1995). As a no-holds-barred critique of mainstream analytic philosophy, Empty Ideas is a continuation of Unger's signature provocative style.

As a former student of his, I spoke to Unger in late May about Empty Ideas, his thoughts on the value of philosophy, Wittgenstein, Bertrand Russell, David Lewis, and the difference between philosophy, crystal healing and self-help (the answer: nothing that important).

Photo2Hi, Peter. To start things off, could you say a bit about your book Empty Ideas, and what it’s about?

Philosophers easily get the idea that somehow or other, just by considering things about the world that they already know, they can write up deep stories which are true, or pretty nearly true, about how it is with the world. By that I especially mean the world of things that includes themselves, and everything that’s spatio-temporally related to them, or anything that has a causal effect on anything else, and so on. They think they can tell a deep story about how it is that all of this stuff really hangs together, that’s much deeper, more enlightening and more comprehensive than anything that any scientist can do.

And so philosophers proceed to write up these stories, and they’re under the impression that they’re saying something new and interesting about how it is about the world, when in fact this is all an illusion. To say new and interesting things about the world — and that’s very hard, things of any generality I mean, or even anything interesting — you really have to engage with a lot of science. And very few philosophers do any of that, at least in any relevant way.

The Chemical Self and the Social Self

by Yohan J. John

6a019b010d0685970b01a511ce30e4970c-320wiThe osmosis of neuroscience into popular culture is neatly symbolized by a phenomenon I recently chanced upon: neurochemical-inspired jewellery. It appears there is a market for silvery pendants shaped like molecules of dopamine, serotonin, acetylcholine, norepinephrine and other celebrity neurotransmitters. Under pictures of dopamine necklaces, the neuro-jewellers have placed words like “love”, “passion”, or “pleasure”. Under serotonin they write “happiness” and “satisfaction”, and under norepinephrine, “alertness” and “energy”. These associations presumably stem from the view that the brain is a chemical soup in which each ingredient generates a distinct emotion, mood, or feeling. Subjective experience, according to this view, is the sum total of the contributions of each “mood molecule”. If we strip away the modern scientific veneer, the chemical soup idea evokes the four humors of ancient Greek medicine: black bile to make you melancholic, yellow bile to make you choleric, phlegm to make you phlegmatic, and blood to make you sanguine.

A dopamine pendant worn round the neck as a symbol for bliss is emblematic of modern society's attitude towards current scientific research. A multifaceted and only partially understood set of experiments is hastily distilled into an easily marketed molecule of folk wisdom. Having filtered out the messy details, we are left with an ornamental nugget of thought that appears both novel and reassuringly commonsensical. But does neuroscience really support this reductionist view of human subjectivity? Can our psychological states be understood in terms of a handful of chemicals? Does neuroscience therefore pose a problem for a more holistic view, in which humans are integrated in social and environmental networks? In other words, are the “chemical self” and the “social self” mutually exclusive concepts?

Taking Standardized Tests in Middle Age: Examining the Doctor

by Carol A. Westbrook

ScreenHunter_691 Jun. 16 10.41The single most important skill you need to practice medicine is the ability to pass multiple-choice exams. Most people saw their last standardized test when college or grad school ended. No so for us doctors– exam taking continues until retirement. The process begins with the high SAT score required for entry into a good college, then a high MCAT to get into medical school. In medical school we complete Steps 1 and 2 of the USMLE (US Medical Licensing Exam) and in residency, Step 3. After residency come the Specialty Boards (e.g. Internal Medicine, Surgery, etc.), then the Subspecialty Boards (e.g. Cardiology, Oncology). It continues with re-certification exams in your specialty every 10 years. It does not end until retirement.

So here I am, in my 60's, having to sit for an exam in order to renew my credentials as a Medical Oncologist. If you haven't taken a standardized test within the last decade you will be surprised to find how things have changed. There is no paper, no filling out circles with No.2 pencils, and no exam booklets. The questions are read on a computer screen, and answered by point-and-click with a mouse. The exams are given at a testing center in a strip mall, where other test-takers may be fireman, manicurists, or hairdressers taking their state licensing exams. After passing triple security (two ID's and a palm print scan) you enter the exam room, where you will be directed to a workstation containing only a computer on an otherwise empty desk. No purses, wallets, watches, pens, cell phones, or calculators are allowed into the room. It is dead silent, and anonymous. Nonetheless, you quickly adapt to the computerized routine, and the exam itself is remarkably similar to any other multiple-choice exam. As always, there are a series of single questions and 4 answers, of which only one is right, including the notorious “all of the above” or “none of the above.”

Scoring well on a multiple-choice exam requires certain skills. You do need at least a passing familiarity with the material, of course, but just as important is a feel for the psychology of the exam–are they trying to trip me up on this question? Is there a hidden trick? Does the exam phrasing suggest a certain emphasis? Also required is precise reading of the question, and facility with English grammar (beware of the double negative!). The most important skill for the test-taker, though, is the ability to “cram”. By cramming, I mean the ability to review and retain a large amount of detailed information for a few days prior to the test.

Parades: Reflections on the Eve of the 2014 Ghana-America World Cup Match

by Mara Jebsen

Thanksgiving-Day-Parade-parkway-600One of my favorite memories is also a mysterious one.It is 2006, and I am in Togo. The first goal struck for the continent of Africa has just been shot by Mohamed Kader. He’s representing the Togolese team, who are making their first and only World Cup appearance. A near-hysterical roar goes up in the neighborhood. I suspect I can hear roars from across the nearby Ghana border, too.

The sound is the invigorating effect of many groups of fans rising out of their seats in thatched roof bars and in courtyards under sticky mango trees. I run up to the balcony at the top of our house to see what’s happening in the street. A parade of shouting boys has collected on a road near the ocean. They are running and waving Togolese flags. An intense color combination results: the yam-dirt road, the brown boys, the dirty whitewashed city walls– and the whipping grass-green, and primary red and yellow of the cheap plastic flags. The boys march and deliver their holler into the big wide sound. Now one particularly small boy, wearing only green underwear, does not have a flag. As I watch, he shimmies his skivvies down over his dry knees, raises them in the air, and, belly thrust out, waves the green underpants round and round, whooping buck-naked for all he’s worth.

I'm not sure why I like this image so much. I’ve tried, in storytelling, to re-enact (without actually undressing) the fluid motion of the boy stripping and whooping without deliberation. He may have been about 7, and he swung the underpants around like a lasso, but with his head held high, proud.

THE ACCIDENTAL SURREAL: A CONVERSATION WITH ARTIST KRISTINA WILLIAMSON

by Jeff Strabone

Kristina Williamson is a multimedia visual artist who can find the erotic in a Cheese Curl, the surreal in the every day, and signs of globalization in the empty village left behind. Her photographs span the globe from her small-town origins somewhere in America to the islands of Greece and Spain. Like Byron's Childe Harold in the ruins of the Acropolis, her new book of photographs in Greece contemplates in the contradictions of modernity what endures of the past and what is 'Gone—glimmering through the dream of things that were'. Her work alternates between domestic, global, eerie, surprising, revelatory, and beautiful—sometimes all in the same image. On the eve of her book's publication I caught up with the artist at her studio in Brooklyn to talk about the project and her new work, which she describes as 'the accidental surreal'.

1KWilliamson_OneYearOnKythera_bookcover

Q: Your new book One Year on Kythera is a monograph of photos from a Greek island no one's ever heard of. Why Kythera and what is this strange vision you had there?

A: I've always been interested in rural communities having grown up in a small town. My first exposure to Greek culture was while living in the Greek precinct of Melbourne, Australia during a semester abroad. I was fascinated by the community's efforts to maintain a satellite of their homeland. So it was a combination of these two things that inspired my research into photographing in rural Greece.

Q: But why Kythera specifically? How did you end up there?

A; It actually started with a book called Portrait of a Greek Mountain Village by Juliet du Boulay. It's an important sociological study of rural Greece written in the late 1960's, early1970's illustrating village life on the island of Evvia and its response to modernization. Originally, I had the idea to revisit this same village thirty years later to see what has become of it. However, when I managed to track down du Boulay she refused to reveal the name and location of the village for concerns that it might bring it some 'uninvited publicity'.

The Mystic Circle: Sufis, Sants & Songs of the Deccan

by Gautam Pemmaraju

Legend has it that Ibrahim Adil Shah II, the medieval Bahmani sultan of Bijapur, styled as jagadguru badshah (master of the world) and author of the famed treatise on classical music in Dakhani, kitab-i-nauras, advised Hindu litigants to go to Paithan in the Marathwada area of upper Maharashtra to have their disputes settled. The ancient imperial capital of the Satavahana kings, also known as Pratishtana in antiquity, was a seat of Sanskritic learning and justice was dispensed there through eminent courts or nyayalayas. The mid-May heat is scorching as we enter the historic inland town on the banks of the river Godavari, which featured prominently as an important town on the trade routes of the past. Ashoka is said to have sent emissaries (or missionaries?) to Petenikas and epigraphic material from the Pitalkhora caves also refer to the town, said to be one of the oldest urban centres in the Deccan. Aside from mentions in Jaina, Buddhist and Brahminical accounts, there are several references to it in outside sources. In Periplus Maris Erytharaei it is known as Paethana and described as a twenty day march from Barygaza (Baruch). Ptolemy also refers to Paithan as the capital of the Andhra king Pulumayi II (138 – 170 CE) and apart from Tagara (Ter), the ancient city was the other important inland market in Dakkhinapatha, or the Deccan. It was known for its textiles and even to this day, Paithani saris are highly regarded.

PaithanSariAd

The curvy narrow streets that wind up through the town bear no indication of its ancient glory. Our destination is the temple of the medieval Maratha bhakti saint Eknath (d 1599). This is Sant Eknath's devghar, his home temple where he worshipped, says Pushkar Gosavi, a builder by profession who lives across the street. Gosavi is also the saint's fourteenth generation descendant—he conducts the affairs of the samasthan, the temple trust, looks after the devghar, and performs several of the religious functions. “It's been 415 years since Nath Maharaj has left” Gosavi tells us, “and we are merely following the ‘route' that he has laid out.” The greatest work of his hallowed ancestor, Gosavi informs us, was to bring together all kinds of folk. Hundreds of people used to gather here for a meal everyday, “typical Marathi style jevan (food), with puranpoli” Gosavi says, distracting me momentarily as my mind wanders off with inwards prayers of an opportune and delicious lunch ahead—such stray thoughts assume great meaning while travelling. He spoke to all people, Gosavi continues, reminding them in more ways than one, through various tales, songs and discourses, abhangs and bharuds (devotional songs), that there was just the one God, and all quarrels on that front are in vain.

Have You Hugged a Concrete Pillar Today?

Bill Gates in his blog, Gates Notes:

ScreenHunter_689 Jun. 15 20.57The car I drive to work is made of around 2,600 pounds of steel, 800 pounds of plastic, and 400 pounds of light metal alloys. The trip from my house to the office is roughly four miles long, all surface streets, which means I travel over some 15,000 tons of concrete each morning.

Once I’m at the office, I usually open a can of Diet Coke. Over the course of the day I might drink three or four. All those cans also add up to something like 35 pounds of aluminum a year.

I got to thinking about all this after reading Making the Modern World: Materials and Dematerialization, by my favorite author, the historian Vaclav Smil. Not only did I learn some mind-blowing facts, but I also gained a new appreciation for all the materials that make modern life possible.

This isn’t just idle curiosity. It might seem mundane, but the issue of materials—how much we use and how much we need—is key to helping the world’s poorest people improve their lives. Think of the amazing increase in quality of life that we saw in the United States and other rich countries in the past 100 years. We want most of that miracle to take place for all of humanity over the next 50 years. As more people join the global middle class, they will need affordable clean energy. They will want to eat more meat. And they will need more materials: steel to make cars and refrigerators; concrete for roads and runways; copper wiring for telecommunications.

How To Respond To Criticism

Mallory Ortberg in The Toast:

Fall in love with whoever criticized you. Don’t walk away until you’ve ruined their marriage.

Whisper their criticism every night to yourself until you have it memorized, word for word. Remember it forever. Have the words stitched into the shroud that covers your body before you’re lowered into the tomb so you and your criticism can embrace one another for eternity.

Do not rise above it. Never rise above anything. The sky is no place for a human.

Be sure not to separate the tone of the criticism from the content. If it was said ungracefully, it cannot be true. If it was said reasonably, it cannot be false.

Send an email explaining why you don’t deserve to be criticized, then another six emails after that, each one explaining the last, like a set of Russian nesting dolls that don’t think it’s your fault.

Set fire to something that was once beautiful.

Philosopher Undine Sellbach discusses sex, flies and fairy tales

Joe Gelonesi at The Philosopher's Zone:

5519366-3x2-300x200Insects don’t seem to count for much. They bite, buzz around, and wreck picnics. They don’t trigger our moral sensibilities in the way that higher order animals might. In fact, for some, insects generate downright moral revulsion. Yet these small presences are closer to our lives than we care to consider.

Not only are they in the rooms we inhabit, but also in our food. At a special event held at the Melbourne Museum in 2012 diners were given an unusual menu. Courses at Bugs for Brunch included scorpions, mealworms and crickets. Also on the menu was a packet of polenta, described as containing ‘up to 10 insects per packet’ and a chocolate bar with ‘up to 80 microscopic insect fragments’.

In the audience that day was Launceston-based philosopher and performer Undine Sellbach. For her, it was the start of some big thinking on small things.

‘What fascinated me is that what appeared to be an event about science and philosophical argument had this very powerful other level where children and their parents were connecting disgust with ambivalence, making new connections and affinities with the bugs,’ she says.

In this moment of realisation a strange reversal came into view, which Sellbach terms an ‘upside- down ethics’.

Do animals have sex for pleasure?

Jason G Goldman at the BBC:

P020xk2tSex, we are told, is pleasurable. Yet you probably wouldn’t think that if you waded through the scientific literature. That's because most scientific accounts of sexual behaviour rest upon evolutionary explanations rather than the more immediately relevant mental and emotional experiences. To say that we have sex because it helps us to preserve our genetic legacies would be entirely accurate, but the more fleeting, experiential, pleasurable aspects of that most basic of social urges would be missing. It would be like staring at a painting with half the colour spectrum removed from it.

One thing we have been curious about, though, is whether we are the only species that experiences sexual pleasure. The question of whether non-human animals enjoy it too is a perennial – and scientifically legitimate – question to ask.

In the last 10 to 15 years, scientific evidence has begun to accumulate that animals do experience a general sensation of pleasure – as anybody who has stroked a cat will know. In 2001, for example, psychologists Jeffrey Burgdorf and Jaak Panskepp discovered that laboratory rats enjoyed being tickled, emitting a sort of chirpy laugh outside the range of human hearing. And not only that, they would actively seek out the feeling.

But does that include carnal pleasure too? One way to find out is to study instances of sex that can't possibly result in procreation – for instance, among two or more males, or females; where one or more individual is sexually immature, or sex that occurs outside of the breeding season.
