The Astonishing Creativity of Your Genes

Veronique Greenwood and Quanta in The Atlantic:

The millimeter-long roundworm Caenorhabditis elegans has about 20,000 genes—and so do you. Of course, only the human in this comparison is capable of creating either a circulatory system or a sonnet, a state of affairs that made this genetic equivalence one of the most confusing insights to come out of the Human Genome Project. But there are ways of accounting for some of our complexity beyond the level of genes, and as one new study shows, they may matter far more than people have assumed.

For a long time, one thing seemed fairly solid in biologists’ minds: Each gene in the genome made one protein. The gene’s code was the recipe for one molecule that would go forth into the cell and do the work that needed doing, whether that was generating energy, disposing of waste, or any other necessary task. The idea, which dates to a 1941 paper by two geneticists who later won the Nobel Prize in medicine for their work, even has a pithy name: “one gene, one protein.”

Over the years, biologists realized that the rules weren’t quite that simple. Some genes, it turned out, were being used to make multiple products. In the process of going from gene to protein, the recipe was not always interpreted the same way. Some of the resulting proteins looked a little different from others. And sometimes those changes mattered a great deal. There is one gene, famous in certain biologists’ circles, whose two proteins do completely opposite things. One will force a cell to commit suicide, while the other will stop the process. And in one of the most extreme examples known to science, a single fruit fly gene provides the recipe for more than 38,000 different proteins.

Do Proteins Hold the Key to the Past?

Sam Knight in The New Yorker:

In October, 2010, an Italian religious historian named Alberto Melloni stood over a small cherrywood box in the reading room of the Laurentian Library, in Florence. The box was old and slightly scuffed, and inked in places with words in Latin. It had been stored for several centuries inside one of the library’s distinctive sloping reading desks, which were designed by Michelangelo. Melloni slid the lid off the box. Inside was a yellow silk scarf, and wrapped in the scarf was a thirteenth-century Bible, no larger than the palm of his hand, which was falling to pieces. The Bible was “a very poor one,” Melloni told me recently. “Very dark. Very nothing.” But it had a singular history. In 1685, a Jesuit priest who had travelled to China gave the Bible to the Medici family, suggesting that it had belonged to Marco Polo, the medieval explorer who reached the court of Kublai Khan around 1275. Although the story was unlikely, the book had almost certainly been carried by an early missionary to China and spent several centuries there, being handled by scholars and mandarins—making it a remarkable object in the history of Christianity in Asia.

Melloni is the director of the John XXIII Foundation for Religious Sciences, an institute in Bologna dedicated to the history of the Church. He had heard of the Marco Polo Bible, but he was unaware of its poor condition until a colleague spotted the crumbling book at an exhibition at the library, in 2008, and pitched a project to restore it and find out more about its past. “It was like a sort of Cinderella among the beautiful sisters,” Melloni said. Like other people accustomed to handling old texts or precious historical objects, Melloni has a special regard for what Walter Benjamin called their aura: “a strange weave of space and time” that allows for an intimation of the world in which they were made. “You have in your hand the manuscript,” Melloni said. “But also the stories that the manuscript is carrying.”

The restoration took eighteen months. Ten thousand pieces of the Bible were reassembled. In the process, Melloni was determined to subject the document to the latest scientific analysis. “We should do on this Bible the type of thing that would be done on the ‘Mona Lisa,’ ” Melloni told his colleagues. He contacted the cultural-heritage center at the Polytechnic University of Milan, the largest scientific school in Italy, to ask advice. In addition to standard conservation tools, like ultraviolet photography and infrared spectroscopy, which is used to study pigments, the experts there suggested proteomics. “It was the first time I heard the word ‘proteomic’ in my life,” Melloni recalled.

Proteomics is the study of the interaction of proteins in living things.

Color Theory

a political statement walks into an art classroom. could be the walls, or her bones, either way she know some white structure will betray her soon. she takes narrative off her body like a coat. her skin the only negative space in the room. they put her here for contrast. they call it diversity. it just look good, you know? makes the lighter colors gunshow pop. you wouldn’t even see her in the dark if not for her teeth. you feel bitten into even though she hasn’t opened her mouth. all the eyes passing over her right now. dissecting her body like a corpse. eyes look just like she did. black center surrounded on all sides by white. a dominant gene. she the center of attention. takes a seat on top of the quota she just filled and gets comfortable. she’ll be here awhile. scribble in the corner of your eye. she pays you no mind. she’s painting entire canvases Black now. tells the teacher she’s making mirrors. she could look at anything Black and call it a mirror. this what Black art mean. catching yourself redhanded. not knowing if it’s from paint or blood. not knowing if basquiat broke the silence or became it. it’s the double take when you realize she’s been painting with bullets. wonder how she got all the color to stick to them like that. where she got all that color in the first place. whose mouth it fell out of. it coats the teachers throat. he says that’s not what art looks like/you can’t sharpen its fangs like that/who knows what might happen if you leave that in a gallery, it could eat everyone alive/and they wouldn’t even know how to hang that up without a noose anyway/a Black body of work is still a Black body. she smiles, like her bones have abandoned her, and breaks how she’s supposed to. you make sure to get every drop of her blood on canvas. it’s not erasure, it’s performance art. watch them photograph her chalk outline and have the nerve to sell it on t-shirts. a Black body of work is still a Black body. and you won’t even let her die properly. you got red paint in your teeth. red paint on every whitewhite wall.

It’s so easy to wash off.

The Unfinished Project of Enlightenment

Brandon Bloch in the Boston Review:

“No one in the world feels the weakness of general characterizing more than I.” So lamented Johann Gottfried von Herder, towering figure of the German Enlightenment, in his 1774 treatise This Too a Philosophy of History for the Formation of Humanity. “One draws together peoples and periods of time that follow one another in an eternal succession like waves of the sea,” Herder wrote. “Whom has one painted? Whom has the depicting word captured?” For Herder, the Enlightenment dream of grasping human history as a seamless whole came up against the irreducible particularity of individuals and cultures.

The German philosopher and social theorist Jürgen Habermas, among the most influential thinkers of our time, grapples with much the same problem in his new work, the title of which reverses the order of Herder’s terms: This Too a History of Philosophy. Published in German last September, Habermas’s History spans over 3,000 years and 1,700 pages. It marks the apogee of a singular career. Like his eighteenth-century precursor, Habermas seeks a thoroughgoing reconceptualization of the sweep of human history. “Philosophical problems,” he writes, are distinctive from merely “scientific” ones in their “synthetic force.” For Habermas, the fragmentation of modern life has hardly exhausted philosophy’s capacity for bold questions and architectonic structure.

Scientific practice is much older than we think

Chad Orzel at the IAI:

In September 1991, a pair of German hikers in the Ötztal Alps, near the border between Austria and Italy, spotted something brown and human-shaped sticking out of a glacier. They immediately reported this to the authorities, thinking they had discovered the body of someone who had died while hiking. While they were correct about it being a dead body, they were a little off on the timing: what they found turned out to be the mummified corpse of a man who had died sometime before 3100 BCE.

The mummy, quickly nicknamed “Ötzi” after the mountains where he was found, was a middle-aged man from the Copper Age, who had been killed by an arrow in the back. His body was quickly frozen into the glacier, along with his clothes and other possessions, leaving it incredibly well preserved. Over the last 29 years, he has been the subject of intense scientific investigation by a wide range of techniques, down to DNA sequencing to determine the species of the hides used to make his clothing, and isotopic analysis to determine the source of the copper ore for his axe. From all these studies, scientists have been able to reconstruct his final days in considerable detail: he was killed in early summer, having been wounded in a fight a few days earlier. His last two meals consisted of ibex meat and grains, one eaten at a much lower altitude than where he was found, suggesting a vivid narrative of battle and pursuit.

If you want to let freedom ring, hammer on economic injustice

Jamelle Bouie in the New York Times:

Since it emerged seven years ago in response to the acquittal of George Zimmerman in the shooting of Trayvon Martin, the Black Lives Matter movement has produced a sea change in attitudes, politics and policy.

In 2016, 43 percent of Americans supported Black Lives Matter and its claims about the criminal justice system; now, it’s up to 67 percent, with 60 percent support among white Americans, compared with 40 percent four years ago. Whereas Democratic politicians once stumbled over the issue, now even Republicans are falling over themselves to say that “black lives matter.” And where the policy conversation was formerly focused on body cameras and chokehold bans, now mainstream outlets are debating and taking seriously calls to demilitarize and defund police departments or to abolish them outright.

But the Black Lives Matter platform isn’t just about criminal justice. From the start, activists have articulated a broad, inclusive vision for the entire country. This, in fact, has been true of each of the nation’s major movements for racial equality. Among black Americans and their Radical Republican allies, Reconstruction — which was still ongoing as of 150 years ago — was as much a fight to fundamentally reorder Southern economic life as it was a struggle for political inclusion. The struggle against Jim Crow, likewise, was also a struggle for economic equality and the transformation of society.

The Racist Roots of New Technology

Stephen Kearse at The Nation:

The modern study of the intersection of race and technology has its roots in the 1990s, when tech utopianism clashed with the racism of tech culture. As the Internet grew into a massive nexus for commerce and leisure and became the heart of modern industry, the ills of tech workplaces manifested themselves online in chat rooms, message boards, and multiplayer video games that were rife with harassment and hate speech. Documenting these instances, a range of scholars, activists, and politicians attempted to combat these ills, but with little success. When the Simon Wiesenthal Center sent letters to Internet providers in 1996 protesting the rise of neo-Nazi websites, for example, the reply it received from a representative of the Electronic Frontier Foundation, a prominent tech lobby, channeled a now commonplace mantra: “The best response is always to answer bad speech with more speech.” Similarly, media studies researcher Lisa Nakamura documented a dismissive comment in a study of the online game LambdaMOO. In response to a failed community petition to curb racial harassment, a detractor countered, “Well, who knows my race unless I tell them? If race isn’t important [then] why mention it? If you want to get in somebody’s face with your race then perhaps you deserve a bit of flak.”

The Unruly Genius of Joyce Carol Oates

Leo Robson at The New Yorker:

Oates’s friend the novelist John Gardner once suggested that she try writing a story “in which things go well, for a change.” That hasn’t happened yet. Her latest book, the enormous and frequently brilliant “Night. Sleep. Death. The Stars.” (Ecco)—the forty-ninth novel she has published, if you exclude the ones she has written under pseudonyms—is a characteristic work. It begins with an act of police brutality, and proceeds to document the multifarious consequences for the victim’s wife and children: alcoholism, low-level criminality, marital breakdown, incipient nervous collapse. In a 1977 journal entry, Oates acknowledged that her work turns instinctively toward what she called “the central, centralizing act of violence that seems to symbolize something beyond itself.” Perhaps the most heavily ironic statement in her œuvre comes in her second novel, “A Garden of Earthly Delights” (1967), when a woman says, “Nobody killed nobody, this is the United States,” while the most characteristic piece of exposition may be found in “Little Bird of Heaven” (2009): “Daddy was bringing me home on that November evening not long before his death-by-firing-squad to a house from which he’d been banished by my mother.”

The History of Zero

Nils-Bertin Wallin in YaleGlobal Online:

The Sumerians were the first to develop a counting system to keep an account of their stock of goods – cattle, horses, and donkeys, for example. The Sumerian system was positional; that is, the placement of a particular symbol relative to others denoted its value. The Sumerian system was handed down to the Akkadians around 2500 BC and then to the Babylonians in 2000 BC. It was the Babylonians who first conceived of a mark to signify that a number was absent from a column; just as 0 in 1025 signifies that there are no hundreds in that number. Although zero’s Babylonian ancestor was a good start, it would still be centuries before the symbol as we know it appeared.

The renowned mathematicians among the Ancient Greeks, who learned the fundamentals of their math from the Egyptians, did not have a name for zero, nor did their system feature a placeholder as did the Babylonian. They may have pondered it, but there is no conclusive evidence to say the symbol even existed in their language. It was the Indians who began to understand zero both as a symbol and as an idea.

Brahmagupta, around 650 AD, was the first to formalize arithmetic operations using zero. He used dots underneath numbers to indicate a zero. These dots were alternately referred to as ‘sunya’, which means empty, or ‘kha’, which means place. Brahmagupta wrote standard rules for reaching zero through addition and subtraction as well as the results of operations with zero. The only error in his rules was division by zero, which would have to wait for Isaac Newton and G.W. Leibniz to tackle.

But it would still be a few centuries before zero reached Europe. First, the great Arabian voyagers would bring the texts of Brahmagupta and his colleagues back from India along with spices and other exotic items. Zero reached Baghdad by 773 AD and would be developed in the Middle East by Arabian mathematicians who would base their numbers on the Indian system. In the ninth century, Mohammed ibn-Musa al-Khowarizmi was the first to work on equations that equaled zero, or algebra as it has come to be known. He also developed quick methods for multiplying and dividing numbers known as algorithms (a corruption of his name). Al-Khowarizmi called zero ‘sifr’, from which our cipher is derived. By 879 AD, zero was written almost as we now know it, an oval – but in this case smaller than the other numbers. And thanks to the conquest of Spain by the Moors, zero finally reached Europe; by the middle of the twelfth century, translations of Al-Khowarizmi’s work had weaved their way to England.

Contribution of Al-Khwarizmi to Mathematics and Geography

N. Akmal Ayyubi in Muslim Heritage:

One of the greatest minds of the early mathematical production in Arabic was Abu Abdullah Muhammad ibn Musa al-Khwarizmi (b. before 800, d. after 847 in Baghdad) who was a mathematician and astronomer as well as a geographer and a historian. It is said that he is the author in Arabic of one of the oldest astronomical tables, of one the oldest works on arithmetic and the oldest work on algebra; some of his scientific contributions were translated into Latin and were used until the 16th century as the principal mathematical textbooks in European universities. Originally he belonged to Khwârazm (modern Khiwa) situated in Turkistan but he carried on his scientific career in Baghdad and all his works are in Arabic.

He was summoned to Baghdad by Abbasid Caliph Al-Ma’mun (213-833), who was a patron of knowledge and learning. Al-Ma’mun established the famous Bayt al-Hikma (House of Wisdom) which worked on the model of a library and a research academy. It had a large and rich library (Khizânat Kutub al-Hikma) and distinguished scholars of various faiths were assembled to produce scientific masterpieces as well as to translate faithfully nearly all the great and important ancient works of Greek, Sanskrit, Pahlavi and of other languages into Arabic. Muhammad al-Khwarizmi, according to Ibn al-Nadîm [1] and Ibn al-Qiftî [2] (and as it is quoted by the late Aydin Sayili) [3], was attached to (or devoted himself entirely to) Khizânat al-Hikma. It is also said that he was appointed court astronomer of Caliph Al-Ma’mun who also commissioned him to prepare abstracts from one of the Indian books entitled Surya Siddhanta which was called al-Sindhind [4] in Arabic [5]. Al-Khwarizmi’s name is linked to the translation into Arabic of certain Greek works [6] and he also produced his own scholarly works not only on astronomy and mathematics but also in geography and history. It was for Caliph al-Ma’mun that Al-Khwarizmi composed his astronomical treatise and dedicated his book on Algebra.

…It is worth remarking that the term al-jabr, in the Latinized form of algebra, has found its way into the modern languages, whilst the old mathematical term algorism is a distortion of al-Khwarizmi’s name.

Tuesday Poem

Bag

I Lost My Medicine Bag
from back when I believed
in magic. It’s made from a doe’s stomach
and holds grizzly teeth and claw,
stones from Tibet and the moon
the garden and the beach
where the baby’s ashes are buried.
Now I expect this bag to cure my illnesses—
I can’t walk and the skin on my back
pulses and moans without a mouth.
The gods exiled me to this loneliness
of pain for their own good reasons.

Grace Must Come for the Debased and Unworthy

Morgan Meis in Church Life Journal:

Jan Rubens was in love, and then he was on the run. Once the affair with Anna of Saxony was discovered and Jan was arrested, he ran back to his wife, Peter Paul’s mother, begging her for forgiveness and for help. Who knows what was in the man’s heart? Maybe the whole ordeal created deep within the soul of Jan Rubens a love of his wife that had never existed before. Maybe the fog of love was lifted from his eyes, the fog of lust cleared away and gone too was the clouding monomania that sets in when a married man runs into the arms of another woman. Maybe one passion had overtaken the mind of Jan Rubens as he fell into this desperate affair with Anna of Saxony, an otherwise difficult woman as the contemporary sources say, and it made him forget about the rest of the world. He started to see everything through the lens of this clawing need, the need to be with Anna of Saxony, the need to manufacture more and more reasons that he spend time with her, work on projects with her, center his life around her. This became a demanding and unforgiving logic. He stopped asking why, he stopped considering his life in any other light than the light of need. He needed to be with Anna of Saxony, dearest Anna, the only woman alive.

Science denialism is not just a simple matter of logic or ignorance

Adrian Bardon in Scientific American:

Bemoaning uneven individual and state compliance with public health recommendations, top U.S. COVID-19 adviser Anthony Fauci recently blamed the country’s ineffective pandemic response on an American “anti-science bias.” He called this bias “inconceivable,” because “science is truth.” Fauci compared those discounting the importance of masks and social distancing to “anti-vaxxers” in their “amazing” refusal to listen to science.

It is Fauci’s profession of amazement that amazes me. As well-versed as he is in the science of the coronavirus, he’s overlooking the well-established science of “anti-science bias,” or science denial.

Americans increasingly exist in highly polarized, informationally insulated ideological communities occupying their own information universes.

I Love Teaching at Penn State, But Going Back This Fall Is a Mistake

Paul M. Kellermann in Esquire:

According to the Chronicle of Higher Education, 63 percent of American colleges and universities are planning to return to in-person classes this fall, with another 17 percent operating from a hybrid model. This likely comes as welcome news to the millions of undergrads desperate for a return to the college atmosphere—an atmosphere where social distancing is virtually nonexistent, except in situations of weak cell service. In college towns, health care providers are prepping for an onslaught. Faculty and staff, meanwhile, feel abandoned, excluded from the decision-making process as a coterie of VPs weighed financial considerations against health risks. Somehow, no one in the ivory tower’s executive suite bothered to take pedagogic concerns into account—or to consult with those who practice pedagogy professionally.

Tattoos, karaoke and a touch of film noir: What it was like to work with Anthony Bourdain in Thailand

Joe Cummings at CNN:

When crew from CNN’s “Anthony Bourdain: Parts Unknown” contacted me in February 2014 to ask for assistance with an upcoming shoot in Thailand, of course I agreed without hesitation.

No food celebrity was more widely loved than Anthony Bourdain at the time, and his posthumous fame and recognition have only grown since. In an era where chefs are the new rockstars, he was Johnny Cash, keeping it raw and real.

Playing down his history in professional kitchens, including Manhattan’s Brasserie Les Halles, he liked to describe himself as a failed chef and talked openly about past substance abuse. He sharply criticized over-hyped TV chefs and the Michelin cult, using his influence instead to praise the street vendors and line cooks who feed most of the world.
