Transmissible Tumors, 1909

Katherine Irving in The Scientist:

In 1909, a chicken breeder approached Rockefeller Institute pathologist Peyton Rous with one of her hens. The chicken had a large, malignant tumor growing from the connective tissue in its breast, and Rous, who had long been fascinated by tumor biology and transmissibility, decided to investigate. He took biopsies and ground up the samples, then passed them through filters to remove any cells. Finally, he injected the mixture into healthy chickens of the same breed and watched as these chickens developed tumors of their own. This was to become the first major result that solid tumors can be infectious and spread through what some researchers at the time called “filterable agents,” now better known as viruses, which weren’t described in detail until the discovery of the electron microscope decades later.

These findings would eventually change the course of cancer research, but when Rous first reported his discoveries in 1910 and 1911, the scientific community was underwhelmed, according to Scripps Research cancer biologist Peter Vogt. “Rous made this big discovery, and at the time it was incredibly ahead of the field,” says Vogt, who coauthored a perspective piece on the virus, later named Rous sarcoma virus, or RSV (not to be confused with respiratory syncytial virus, also abbreviated to RSV). “People either didn’t believe him or belittled his work.”

What does the sexual revolution look like today?

Phoebe Maltz Bovy in The Hedgehog Review:

I’m not Michel Foucault, but here’s a history of sexuality, greatly abridged: First came the slut shamers. The traditionalist, patriarchal religious haranguers. Things weren’t great for men in the before times, but they were particularly unpleasant for women. Then came the sexual revolution of the 1960s and ’70s, which involved chucking all the rules. This had some good effects (ambitious women at last permitted to leave their houses and become doctors, lawyers, bosses) and some less good ones (moviemakers permitted to assault underage girls). In the 1990s and early 2000s, following however many backlashes against backlashes, the sexual revolution re-emerged as sex positivity.

In theory, sex positivity is friendlier to women than sexual liberation (more negotiated nonmonogamy, fewer bunny girls). It involves applying an open-minded but gender-neutral approach to sex and relationships. This is not the same as overtly catering to men but amounts to the same thing.

Earth’s Orbit Is About to Get More Crowded

Sarah Scoles in Undark:

SOMETIME THIS COMING March, a network of 10 small satellites winged with solar panels is scheduled to launch into Earth’s low orbit. Though likely invisible to the naked eye, the satellites will be part of a future herd of hundreds that, according to the Space Development Agency, or SDA, will bolster the United States’ defense capabilities.

The SDA, formed in 2019, is an organization under the United States Space Force, the newly formed military branch that operates and protects American assets in space. And like all good startups, the agency is positioned as a disruptor. It aims to change the way the military acquires and runs its space infrastructure. For instance, the forthcoming satellite network, called the National Defense Space Architecture, will collectively gather and beam information, track missiles, and help aim weapons, among other tasks.

The SDA’s vision both mimics and relies on shifts that started years ago in the commercial sector: groupings of cheap little satellites — often weighing hundreds of pounds, instead of thousands — that together accomplish what fewer big, expensive satellites used to.

Inequality might be going down now

Noah Smith in Noahpinion:

One name you don’t hear a lot these days is Thomas Piketty. In 2013, the French economist burst into the popular consciousness with the publication of Capital in the Twenty-First Century. The basic thesis was that unless extraordinary forces — war, or massive government action — intervened, capitalism would naturally tend toward greater and greater inequality. That thesis was summarized by the famous and pithy formula “r>g”, meaning that if the rate of return on capital is greater than the growth rate of the economy as a whole, inequality mechanically increases. In Piketty’s telling, only the extraordinary combination of the Great Depression, the New Deal, World War 2, and rapid postwar growth managed to save us from a social collapse due to spiraling inequality in the early 20th century, and now we were back in the danger zone.

Plant Of The Month: Guinea Grass

Hannah Rachel Cole at JSTOR Daily:

Yet something strange happened in the history of this ostensibly symbiotic relationship. Although guinea grass was meant to support the sugar economy by feeding its beasts of burden, ironically, it became a virulent weed to the sugarcane plants. By 1977, guinea grass was rated the number one weed to sugarcane in Cuba. In 2012, the journal of the National Botanical Garden of Cuba (Revista del Jardín Botánico Nacional) listed it as one of the top 100 most noxious weeds on the island and an invasive species of greatest concern.

In this way, the two imported grasses became stalky antagonists in the daily competition for light, water, and soil nutrients. Their cultural meanings, however, had long since diverged. If sugarcane supported the economic interests of European planters, guinea grass was appropriated by enslaved and marooned Africans across the Caribbean for practical and religious purposes. Diasporic Africans in the Virgin Islands used the dried grass to make masquerade costumes for Carnival and other festivals.

On The Technical Disaster Movie

Trevor Quirk at The Point:

The invisibility of the disaster presents a serious difficulty to the filmmakers, who need their viewers to perceive it as the expert does. Their ingenious solution is found in the technical disaster movie’s pronounced ambience: the bustled score and sweaty palettes of ContagionChernobyl’s ghostly clanks and drones; the blare of Bloomberg terminals and pristine skylines of Margin Call. Through these effects, viewers are invited to pretend we know things we manifestly do not. We work through the night with Sullivan as he discovers his financial firm’s impending demise, study his stubbled face as he looks up from his illegible scrawl of equations before a pulsing monotone—and we simply know he’s uncovered something. The camera of Contagion fixates upon “fomites” (common objects that facilitate disease transmission), such that we learn to almost see viruses slithering over bus handles, glassware and casino chips. Chernobyl represents the presence of radiation with the throaty static of dosimeters (audible radiological instruments) that is often so loud and unnerving we forget we don’t exactly know what the sound means. Technical knowledge becomes an artificial sensorium, a collage of abstractions forced onto the nerve endings, always attempting to compensate for its baselessness.

The Science of Awe

Hope Reese in The New York Times:

Awe can mean many things. It can be witnessing a total solar eclipse. Or seeing your child take her first steps. Or hearing Lizzo perform live. But, while many of us know it when we feel it, awe is not easy to define. “Awe is the feeling of being in the presence of something vast that transcends your understanding of the world,” said Dacher Keltner, a psychologist at the University of California, Berkeley.

It’s vast, yes. But awe is also simpler than we think — and accessible to everyone, he writes in his book “Awe: The New Science of Everyday Wonder and How It Can Transform Your Life.” While many of us associate awe with dramatic, life-changing events, the truth is that awe can be part of everyday life. Experiencing awe comes from what Dr. Keltner has called a “perceived vastness,” as well as something that challenges us to rethink our previously held ideas. Awe can be triggered from moments like seeing the Grand Canyon or witnessing an act of kindness. (About a quarter of awe experiences are “flavored with feeling threatened,” he said, and they can arise, for example, by looking at a lion in a zoo or even gruesome videos of genocide).

Scientists Uncover a Gut-Brain Connection for Social Development

From SciTechDaily:

To learn to socialize, zebrafish need to trust their gut. Gut microbes encourage specialized cells to prune back extra connections in brain circuits that control social behavior, new University of Oregon research in zebrafish shows. The pruning is essential for the development of normal social behavior.

The researchers also found that these ‘social’ neurons are similar in zebrafish and mice. That suggests the findings might translate between species — and could possibly point the way to treatments for a range of neurodevelopmental conditions. “This is a big step forward,” said University of Oregon neuroscientist Judith Eisen, who co-led the work with neuroscientist Philip Washbourne. “It also sheds light on things that are going on in larger, furrier animals.” The team reports their findings in two new papers, published in PLOS Biology and BMC Genomics.

While social behavior is a complex phenomenon involving many parts of the brain, Washbourne’s lab previously identified a set of neurons in the zebrafish brain that are required for one particular kind of social interaction. Normally, if two zebrafish see each other through a glass partition, they’ll approach each other and swim side by side. But zebrafish without these neurons don’t show interest. Here, the team found a pathway linking microbes in the gut to these neurons in the brain. In healthy fish, gut microbes spurred cells called microglia to prune back extra links between neurons.

Why Did The Loyalists Flee?

by Terese Svoboda

We must all hang together, or assuredly we shall all hang separately. –Ben Franklin

Watching the Oathkeepers cry during the federal court trials under the charge of sedition, I considered the fate of seditious Loyalists during the Revolutionary War whom they most closely resemble in the topsy-turvy world of contemporary politics. The Revolutionary War was a civil war, combatants were united with a common language and heritage that made each side virtually indistinguishable. Even before hostilities were underway, spies were everywhere, and treason inevitable. Defining treason is the first step in delineating one country from another, and indeed, the five-member “Committee on Spies’ ‘ was organized before the Declaration of Independence was written.[1]  But the records of the courts handling  treason during the Revolutionary War are handwritten and difficult to read, especially on microfilm, according to Bertrand Roehner, the historiographer I mentioned in my last column, who works at the Sorbonne.[2]

Historiography is the study of how historical recording and interpretations shift with time as a result of many factors. Roehner helped me collect documentation available on violence in postwar Japan for my 2008 memoir, Black Glasses Like Clark Kent, sharing information from his research into Allied Occupation archives in Australia, Britain and New Zealand, and from Japanese and American newspapers. I was specifically looking for evidence of executions of Americans convicted by US forces, but I was also interested in the Japanese response to GIs in that period. What Roehner gleaned contradicted the premise of John W. Dowers’ Pulitzer-winning book Embracing Defeat, which frames the Japanese as meek losers, resigned to their status and reliant solely on Americans for their welfare. Dowers omits the huge demonstrations organized by the Japanese populace that took place periodically, the guerilla snipers and mysterious murders and rail sabotage – as well as the many acts of violence committed by the Americans – rape, automobile “accidents.” Dower had not reviewed or could not access Roehner’s sources, partly due to MacArthur’s policy of total censorship – even the mention of censorship was forbidden – that has only recently been lifted in Japan. While we would like to consider our side of the Revolutionary War terror- and violence-free, carried out by well-behaved Americans, the truth might be that we won the war because we were just as (or more) violent as our opponent — which would explain why 200,000 Loyalists left their homes and went into exile.[3] Read more »

Monday Poem—Happy New Year . . .

Poets Talk Time

poets talk time
to get a handle on it,
to hack a place to hold it
to turn it, to fold it
to climb it and mount it
to ride it, to flip it
to hide it, to turn it
to toy with and tip it
to wrench it, to rip it
apart to unlearn it
to kill it, to burn it
to track it in the innards of clocks
to tear it to shreds like a crow on a corpse
to drill it to dig it to bore it
and finally, ignore it

but poets would do well to pour time
like water, or blood & wine
and, savoring,
sip it

Elon Musk Buys Twitter, Gets On Route 230

by Michael Liss

Norman Rockwell, “Freedom of Speech.” Story illustration for The Saturday Evening Post, February 20, 1943. Norman Rockwell Museum Collections. ©SEPS: Curtis Publishing, Indianapolis, IN.

I’ve always liked this image. It’s quiet, it sneaks up on you, brings back old memories of pizza parlors, barbershop walls and drug-store soda fountains.

Norman Rockwell’s “Four Freedoms” had been inspired by FDR’s 1941 Annual Message, given at a time when Germany had swept through much of Europe, and democracy was in great peril. While the United States was not then yet at war, and isolationism was still strong, a growing number of Americans could see that our involvement might be inevitable. Roosevelt wanted to define the values that a post-war world would embrace. Drawing from the Constitution as well as from the lived experience of the Depression, FDR called for Freedom from Want, Freedom from Fear, Freedom of Worship and Freedom of Speech.

This one is Rockwell’s masterpiece. The composition was, according to him, inspired by a town meeting he had attended, where a young man took an unpopular position. Rockwell portrays him with shoulders thrown back a bit as he speaks, as if to project his unamplified voice through the hall. His hard, weathered hands hold the chair in front of him, a copy of a Town Report folded in his pocket. His face is roughened by the sun and wind, he’s flanked by two older men in white shirts and ties, and, on the face of one, there’s a small smile. No screaming, no doxing, and certainly no video captured on someone’s phone, uploaded, and seen by hundreds of thousands of partisans.

Rockwell’s painting gets to the essence of “Constitutional” free speech. However contrary this speaker’s opinion is, it is his right to voice it at a public hearing without fear of punishment. The First Amendment has very few content-based exceptions—the government can intervene only where obscenity, defamation, fraud, incitement, and speech integral to criminal conduct is involved.

Neil Postman and the Two Cultures

by Jeroen Bouterse

In 2022, I worked harder than before to keep my students’ tables free of smartphones. That this is a matter for negotiation at all, is because on the surface, the devices do so many things, and students often make a reasonable, possibly-good-faith case for using it for a specific purpose. I forgot my calculator; can I use my phone? No, thank you for asking, but you won’t be needing a calculator; just start with this exercise here, and don’t forget to simplify your fractions. Can I listen to music while I work? Yeah, uhm, no, I happen to be a big believer in collaborative work, I guess. Can I check my solutions online please? Ah, very good; but instead, use this printout that I bring to every one of your classes these days. I’m done, can I quickly look up my French homework? That’s a tough one, but no; it’s seven minutes to the bell anyway and I prepared a small Kahoot quiz on today’s topic. (So everyone please get your phones out.)

As a matter of classroom management, some of these questions are more of a judgment call than eating and drinking in class (not allowed, with some exceptions immediately after a PE lesson) but less complicated than bathroom visits (allowed in principle, but in need of limits that I may never be able to express algorithmically). In spite, however, of the superficial similarities between these phenomena – all subject to teacher- and class-specific settlements, informed and assisted by school-wide institutions such as regulations and phone bags – it feels as if more is at stake when it comes to smartphones. I sense more urgency, as if I’m laboring to stop a tide from coming in; as if what I am inclined to view as ‘complex’ and ‘multi-faceted’ and ‘also an interesting challenge, actually’ is actually one big thing only: an external force threatening to infiltrate my classroom and undo what I am trying to achieve there (which is called ‘education’ and which is therefore plainly also one big thing). I don’t feel this way about chewing gum.

To help me make up my mind, I decided to consult a writer who passed away before smartphones were ‘a thing’: media and educational philosopher Neil Postman, famous for his criticism of the role of television in modern culture and education. Though this choice of authority seems to be loading the dice rather heavily in one direction, I did briefly consider the counterintuitive case that Postman might have seen 21st-century media technology as a step in the right direction. In the end, however, I think the more predictable reading – that, in Aubrey Nagle’s words, mobile media represent “Postman’s fear of TV on steroids” – is the more interesting one, allowing us to apply his broader cultural criticism to our time.

Theagony: 2022 adieux

by Rafaël Newman

William Blake, “Satan Before the Throne of God” (1805-1810)

When we began, our gods were junior,
Their profits, and our problems, punier.
The deities who drilled at dawn
Paraded in a pantheon:
Born out of Chaos and castration,
Theirs was a piebald population.
They mingled with a breed of men
And women we’ll not see again,
Who shared those gods’ own groaning board,
Where things were rarely untoward—
Unless you count the odd abduction,
The semi-bestial seduction,
The anthropophagous pot-au-feu,
Or the Promethean pas-de-deux.

But more than this, our gods were many,
Though not, for all that, two-a-penny.
A deathless numen dwelt within
Whatever was, would be, had been,
And granted every abstract noun
Its aegis, buckler, crest, or crown;
Its anvil, lightning bolt, caduceus;
Its cuneiform, and its cartouches.
There was a holiness at large,
A broadly scattered, sacred charge.

But now? Our gods have been compress’d,
And we, in consequence, less bless’d:
From Twelve Olympians downgraded
To single Seigneur. We have traded
That polychrome diapason
For a grimly grayscale monotone.
At best, our world is Manichaean,
Though not as praised in Persian paean.
The tyrants twain who rule this globe
Are those that frame the Book of Job:
A sadist, distant from the Earth,
And Satan, who assays the worth,
In worship and obedience,
Of hominid ingredients. Read more »

Rumi and the Clock of Shams Tabrizi

by Shadab Zeest Hashmi

A tree in the vicinity of Rumi’s tomb has me transfixed. It isn’t the tree, actually, it is the force of attraction between tree-branch and sun-ray that seems to lift the tree off the ground and swirl it in sunshine, casting filigreed shadows on the concrete tiles across the courtyard. The tree’s heavenward reach is so magnificent that not only does it seem to clasp the sun but it spreads a tranquil yet powerful energy far beyond itself. It is easy to forget that the tree is small. I consider this my first meeting with Shams.

Of average human-height, the tree is non-descript, other than how its heavenward reaching creates an embrace that enricles and enlarges everything around it, so that motion ripples out of stillness, light edges shadows. In a moment such as this, the senses deepen spirit; words fail, words fail. All that we know evaporates, we are left with spirit. Here is the limit of knowledge, the Sufis teach us; no amount of book learning alone can bring us closer to the Divine than the spirit engaged in making a wide embrace. The Divine is an experience, and knowledge is only a part of it. If there is one word that comes close to describing this, it is love. But of course, the word is insufficient. No single word in conventional language can contain love. Poetry, arguably, owes its existence to the impossibility of defining love in the dictionary. In Maulana Rumi’s case, it was Shams who brought this awakening, this great desire for the Divine beloved that colored every thought, action and word that was to come out of him in the future.

Plagiarism in the Era of AI

by Akim Reinhardt

2001: A Space Odyssey's HAL 9000 Was Originally a Female | Smart News| Smithsonian Magazine
HAL

The ChatGPT Bot has changed everything! That’s the basic vibe I’m getting from frantic press reports, early return think pieces, and even public-facing academicians. Specifically, this new, free AI software, only a few weeks old and still improving, is already churning out high school-quality essays on just about any subject a teacher might assign, and it now stands as a real threat to the very concept of high school and even college term papers.

As a History professor myself, I suppose I should be duly panicked. However, I don’t see the rise of the bot as something to fear or even resent. That’s not to say there isn’t cause for concern. There absolutely is, and adjustments are required.  But my own personal history leads me to see charlatanism as something you simply have to deal with. Growing up in New York City, we learned to dodge it from a young age, with an understanding that it was up to us to spot it. Suckers may not deserve to get taken in a sidewalk game of Three Card Monty, as hustlers love to claim, thereby muddying their own immorality. However, even if the victims are to be pitied, suckers fill an ecological niche: they function as an object lesson to the rest of us: Don’t be like them. Don’t be a chump. I also wasn’t a very good undergraduate college student, though I didn’t cheat (too much pride, not enough giving a shit).

Add it all up, and I’m primed to stop cheaters. I know how a lazy student thinks, and I’m always on the alert, guarding against getting taken. I’ve also been designing and grading college student assignments for close to a quarter-century. So for me, this new AI bot is not scarey, or even revolutionary. It’s just the latest con for those who would seek to dupe me out of my most prized professional possession: passing grades. A quick rundown shows how the academic bunko game has changed just in my time as a professor. Read more »
