Sean Carroll’s Mindscape Podcast: Elizabeth Strychalski on Synthetic Cells and the Rules of Biology

Sean Carroll in Preposterous Universe:

Natural selection has done a pretty good job at creating a wide variety of living species, but we humans can’t help but wonder whether we could do better. Using existing genomes as a starting point, biologists are getting increasingly skilled at designing organisms of our own imagination. But to do that, we need a better understanding of what different genes in our DNA actually do. Elizabeth Strychalski and collaborators recently announced the construction of a synthetic microbial organism that self-reproduces just like a normal unicellular creature. This work will help us understand the roles of genes in reproduction, one step on the road to making DNA molecules and artificial cells that will perform a variety of medical and biological tasks.

Yep, it’s bleak, says expert who tested 1970s end-of-the-world prediction

Edward Helmore in The Guardian:

Herrington, a Dutch sustainability researcher and adviser to the Club of Rome, a Swiss thinktank, has made headlines in recent days after she authored a report that appeared to show a controversial 1970s study predicting the collapse of civilization was – apparently – right on time.

Coming amid a cascade of alarming environmental events, from western US and Siberian wildfires to German floods and a report that suggests the Amazon rainforest may no longer be able to perform as a carbon sink, Herrington’s work predicted the collapse could come around 2040 if current trends held.

Research by Herrington, a rising star in efforts to place data analysis at the center of efforts to curb climate breakdown, affirmed the bleaker scenarios put forward in a landmark 1972 MIT study, The Limits to Growth, that presented various outcomes for what could happen when the growth of industrial civilization collided with finite resources.

Bad Poems for the Death of Children

Perri Klass at The Hudson Review:

Julia Ann Moore (1847–1920), the “Sweet Singer of Michigan,” was one of the worst American poets of the nineteenth century, or perhaps of any century. Her ear for the clunky inverted phrase, or the just-miss rhyme, generated bad verse on patriotic themes and historical subjects, but what really inspired her was obituary poetry, a genre which thrived all through the nineteenth century, and which drew steadily on the talent—or lack of talent—of local amateur commemorative poets. And her specialty within a specialty was obituary poetry for those dying young: “Every time one of my darlings died, or any of the neighbor’s children were buried, I just wrote a poem on their death,” she told an interviewer from the Chicago Daily Inter Ocean in 1878. “That’s the way I got started.”

de Kooning and Soutine

Griffin Oleynick at Commonweal:

It’s not hard to see what first drew Barnes and de Kooning to Soutine. His arresting portraits from the 1910s and ’20s, the first works on view, reveal both a wry distrust of himself and a sure confidence in his capacity to observe and render the inner lives of other people. In his laconic 1918 Self-Portrait, he’s clothed in a rumpled blue smock and stares straight ahead at the viewer; another portrait (evidently by Soutine) covers his right shoulder and fills the left side of the frame. Soutine is clearly channeling similar works by artists like Velázquez and Rembrandt, which he regularly studied in his frequent trips to the Louvre. Yet his own Self-Portrait, geometrically and chromatically centered on his puffy, blood-red lips, also evokes the grotesque—so called because it traditionally portrayed subjects best kept out of sight. After Barnes helped make him famous, Soutine began to appear at Parisian salons in elegant clothes (indeed, Polish writer and painter Józef Czapski calls attention to his “expensive felt hats and gleaming leather boots”), yet he remained something of an outsider.

The Risks and Rewards of Stepping Back from the World

Cal Flyn at Literary Review:

Time after time, Segnit meets the most skilled practitioners, the most enlightened minds on the planet, and time after time they fail to find the words. Early on we are introduced to Sister Nectaria, an elderly nun who has lived at a remote monastery on a Greek island since the age of eleven. She is, says Segnit, ‘a living, breathing, invocation of god’. But she finds his questions irritating, or invasive, or beside the point. Later, we meet Tenzin Palmo, a British woman formerly known as Diane Perry who spent twelve years meditating alone in a cave in the Himalayas. ‘I hardly remember any of it,’ she insists. ‘At the time it seemed very ordinary.’

In the Eastern Orthodox Church, God exists beyond knowledge and can only be described in terms of what He isn’t. This is apophasis, Segnit tells us, ‘the language of the unsayable’.

CRISPR injected into the blood treats a genetic disease for first time

Jocelyn Kaiser in Science:

CRISPR-Cas9 gene editing complex, molecular structure. The CRISPR-Cas9 protein is used in genome engineering to cut DNA (deoxyribonucleic acid). It uses a guide RNA (ribonucleic acid) sequence to cut DNA at a complementary site. The Cas9 protein is shown in white. The guide RNA is blue, and the double-strand of the DNA is green.

The gene editor CRISPR excels at fixing disease mutations in lab-grown cells. But using CRISPR to treat most people with genetic disorders requires clearing an enormous hurdle: getting the molecular scissors into the body and having it slice DNA in the tissues where it’s needed. Now, in a medical first, researchers have injected a CRISPR drug into the blood of people born with a disease that causes fatal nerve and heart disease and shown that in three of them it nearly shut off production of toxic protein by their livers.

Although it’s too soon to know whether the CRISPR treatment will ease the symptoms of the disease, known as transthyretin amyloidosis, the preliminary data reported today are generating excitement about what could be a one-time, lifelong treatment. “These are stunning results,” says gene editing researcher and cardiologist Kiran Musunuru of the University of Pennsylvania, who was not involved in the trial. “It exceeds all my expectations.”

The work also marks a milestone for the race to develop treatments based on messenger RNA (mRNA), the protein-building instructions naturally made by cells. Synthetic mRNAs power two COVID-19 vaccines being given to millions of people to fight the coronavirus pandemic, and many companies are working on other mRNA vaccines and drugs. The new treatment, which includes an mRNA encoding one of CRISPR’s two components, “begins the convergence of the fields of CRISPR and mRNA,” says cardiovascular researcher Kenneth Chien of the Karolinska Institute, a co-founder of Moderna, which makes one of the COVID-19 vaccines and is also developing mRNA drugs.

Against Persuasion

Agnes Callard in Boston Review:

Philosophers aren’t the only ones who love wisdom. Everyone, philosopher or not, loves her own wisdom: the wisdom she has or takes herself to have. What distinguishes the philosopher is loving the wisdom she doesn’t have. Philosophy is, therefore, a form of humility: being aware that you lack what is of supreme importance. There may be no human being who exemplified this form of humility more perfectly than Socrates. It is no coincidence that he is considered the first philosopher within the Western canon.

Socrates did not write philosophy; he simply went around talking to people. But these conversations were so transformative that Plato devoted his life to writing dialogues that represent Socrates in conversation. These dialogues are not transcripts of actual conversations, but they are nonetheless clearly intended to reflect not only Socrates’s ideas but his personality. Plato wanted the world to remember Socrates. Generations after Socrates’s death, warring philosophical schools such as the Stoics and the Skeptics each appropriated Socrates as figurehead. Though they disagreed on just about every point of doctrine, they were clear that in order to count themselves as philosophers they had to somehow be working in the tradition of Socrates.

What is it about Socrates that made him into a symbol for the whole institution of philosophy? Consider the fact that, when the Oracle at Delphi proclaims Socrates wisest of men, he tries to prove it wrong. As Plato recounts it in the Apology:

I went to one of those reputed wise, thinking that there, if anywhere, I could refute the oracle and say to it: “This man is wiser than I, but you said I was.” Then, when I examined this man—there is no need for me to tell you his name, he was one of our public men—my experience was something like this: I thought that he appeared wise to many people and especially to himself, but he was not. I then tried to show him that he thought himself wise, but that he was not. As a result he came to dislike me, and so did many of the bystanders. So I withdrew and thought to myself: “I am wiser than this man; it is likely that neither of us knows anything worthwhile, but he thinks he knows something when he does not, whereas when I do not know, neither do I think I know; so I am likely to be wiser than he to this small extent, that I do not think I know what I do not know.”

If Socrates’s trademark claim is this protestation of ignorance, his trademark activity is the one also described in this passage: refuting the views of others.

“She smelled the way the Taj Mahal looks by moonlight,” and other iconic Raymond Chandler lines

Dan Sheehan in Literary Hub:

Today marks the 133rd anniversary of the birth of Raymond Chandler, patron saint of Los Angeles noir and perhaps the most famous crime fiction writer of all time. Each of his nine novels, from The Big Sleep (1939) to the posthumously published Playback (1953), center around iconic gumshoe Philip Marlowe—Chandler’s wisecracking, whiskey-drinking, tough-as-an-old-boot fictional private investigator so memorably portrayed on screen by (among many, many others) Humphrey BogartElliot Gould, and Robert Mitchum—as he navigates the murky underbelly of the City of Angels. Our sister site CrimeReads has more fascinating Chandler content than you can shake a .32 revolver at, and to mark this auspicious anniversary I thought I’d follow their lead by tracking down (and roughing up) some of his most Raymond Chandler-y lines.

“I was as hollow and empty as the spaces between stars.”

The Idea That Trees Talk to Cooperate Is Misleading

Kathryn Flinn in Scientific American:

Trees that communicate, care for one another and foster cooperative communities have captured the popular imagination, most notably in Suzanne Simard’s much-praised book Finding the Mother Tree, soon to be a movie, and in other works like James Cameron’s Avatar, Peter Wohlleben’s The Hidden Life of Trees and Richard Powers’ Pulitzer Prize–winning novel The Overstory.

But many scientists like myself believe these depictions misrepresent ecosystems and harm the cause of conservation.

Do trees really talk? Sure. Plants emit hormones and defense signals. Other plants detect these signals and alter their physiology accordingly. But not all the talk is kind; plants also produce allelochemicals, which poison their neighbors.

Although neoclassical economics relies on assumptions that should have been discarded long ago, it remains the mainstream orthodoxy

James K. Galbraith in Project Syndicate:

Self-regarding economics departments at prestigious academic institutions no longer bother to teach the history of economic thought – a field that I studied at Yale University in 1977, forever compromising my academic career. Why was the topic abandoned – and even shunned and mocked? Students with a skeptical turn of mind would not be wrong to suspect that it was for scandalous reasons (as when, in past centuries, inconvenient aunts were locked away in garrets).

The four books reviewed here each uncover parts of the scandal. Three are brand new, and the other, The Corruption of Economics, first appeared in 1994 and was re-issued in 2006. Its principal author, the American economist Mason Gaffney, kept his remarkable pen flowing until passing away last summer at the age of 96.

Robert Skidelsky is a historian, an epic biographer of John Maynard Keynes, and a prolific debater in the United Kingdom’s House of Lords. He calls What’s Wrong with Economics? a “primer,” and it is indeed the most accessible of the four books. Skidelsky’s education in the history of economics resembles my own: a wide reading of the classical authors – Adam Smith, David Ricardo, Karl Marx, and others – followed by those associated with the “neoclassical” or “marginalist” revolution of the 1870s.

Sympathy for the Devil

Janique Vigier in Bookforum:

SINCE THE 2014 RELEASE of Outline, the first novel in her acclaimed trilogy, Rachel Cusk has acquired an aura of unimpeachability. This is not to say all reviews of her work have been positive; many invoke the question of “likability,” that awful barometer women are metered against, but the general tone conveys her moral fiber, her strength of character. Not only is her work brilliant, but she herself stands as a kind of moral benchmark. Her position on her themes—womanhood, fate, will, art—has been taken as correct. This is likely in part because she has not come by her reputation easily (attacks on her memoirs, particularly the divorce tale Aftermath, were vicious), nor at a young age (she is now fifty-four).

Second Place, Cusk’s latest novel, begins from the perch of moral certainty, and never quite lets go. A psychosexual drama with no sex, the book revolves around two characters, referred to only as L and M. L is a male artist, M a female patron. The novel centers around the questions these differences reveal. Or, closer to the truth: these questions and differences reveal Cusk’s predetermined moral universe. Questions are illusory; there are deterministic stances. The standpoint of the main characters reflects this. L, fey and ascetic, is a thinly disguised version of D. H. Lawrence, whom Cusk has called her mentor. L is a painter, not a writer, but the specter of Male Genius is made clear. His foil, M, the writer-narrator, reveres his paintings, seeing him, by extension, as a kind of oracle. She makes the natural assumption and casual error of conflating the virtues of the work with the character of the artist. Cusk’s own devotion to Lawrence makes these metatextual tricks all the more fraught. Is there a more intimate and controlling way to pay homage to your literary idol than by turning him into a fictional character?

It’s a funny time to write a novel about Lawrence, though not necessarily more so than any other: too romantic to be modern, accused by his contemporaries of being a pornographer—that is, part of the avant-garde—he has never been contemporary, not even in his own time. A man whose tragedy, according to Angela Carter, was that “he thought he was a man,” a pious man who wrote frankly about sex, Lawrence suffered his aloneness. Poor, childless, mostly itinerant, he shares little biographical similarity with Cusk, who has turned her children, her career success, and her home into subjects for her fiction. What the two writers do share is a basic and unassailable belief in the individual, a belief that underwrites their obsessive preoccupation with will, intuition, and transformation. Above all it’s women—as question and problem—that drive their work and fetter their hearts. How can women give voice to themselves? What can love look like? And freedom?

Plants Feel Pain and Might Even See

Peter Wohlleben in Nautilus:

In 2018, a German newspaper asked me if I would be interested in having a conversation with the philosopher Emanuele Coccia, who had just written a book about plants, Die Wurzeln der Welt (published in English as The Life of Plants). I was happy to say yes.

The German title of Coccia’s book translates as “The Roots of the World,” and the book really does cover this. It upends our view of the living world, putting plants at the top of the hierarchy with humans down at the bottom. I had been giving a great deal of thought to this myself. Ranking the natural world and scoring species according to their importance or their superiority seemed to me outdated. It distorts our view of nature and makes all the other species around us seem more primitive and somehow unfinished. For some time now, I have not been comfortable with viewing humans as the crown of creation, separating animals into higher and lower life-forms, and treating plants as something on the side, definitively banished to a lower level.

And so I found the conversation with Coccia most refreshing when he visited our Forest Academy. A small bearded man, Coccia turned up in a blue suit and blue checkered tie, completely inappropriate attire for the outdoors, even though we had agreed that we would take a walk in the forest together. Although he is from Italy and now teaches in France and writes in French, he also speaks fluent German because at one time he studied and worked in Freiburg.

After our first cup of coffee, we were soon deep into our main topic: trees and plants in general. Coccia argued that our biological classifications are not grounded in science. They are strongly influenced by theology and are dominated by two ideas: the supremacy of the human race and the world as a place humans must bend to their will. And then there is our centuries-old compulsion to categorize everything. When you combine these concepts, you get a ranking system that puts humankind at the top, animals in the middle, and plants way down at the bottom.

I listened, fascinated by what he had to say.

Sunday Poem

Grandmother

my grandmother
doesn’t know pain
she believes that
famine is nutrition
poverty is wealth
thirst is water
her body like a grapevine winding around a walking stick
her hair bees’ wings
she swallows the sun-speckles of pills
and calls the internet the telephone to america
her heart has turned into a rose the only thing you can do
is smell it
pressing yourself to her chest
there’s nothing else you can do with it
only a rose
her arms like stork’s legs
red sticks
and i am on my knees
howling like a wolf
at the white moon of your skull
grandmother
i’m telling you it’s not pain
just the embrace of a very strong god
one with an unshaven cheek that prickles when he kisses you.

Scott Aaronson remembers Steven Weinberg (1933-2021)

Scott Aaronson in Shtetl-Optimized:

Steven Weinberg was, perhaps, the last truly towering figure of 20th-century physics. In 1967, he wrote a 3-page paper saying in effect that as far as he could see, two of the four fundamental forces of the universe—namely, electromagnetism and the weak nuclear force—had actually been the same force until a tiny fraction of a second after the Big Bang, when a broken symmetry caused them to decouple. Strangely, he had developed the math underlying this idea for the strong nuclear force, and it didn’t work there, but it did seem to work for the weak force and electromagnetism. Steve noted that, if true, this would require the existence of a new particle that hadn’t yet been seen — the Z boson — and would also require the existence of the previously-proposed Higgs boson.

By 1979, enough of this picture (in particular, the Z boson) had been found that Steve shared the Nobel Prize in Physics with Sheldon Glashow—Steve’s former high-school classmate—as well as with Abdus Salam, both of whom had separately developed pieces of the same puzzle. As arguably the central architect of what we now call the Standard Model of elementary particles, Steve was in the ultra-rarefied class where, had he not won the Nobel Prize in Physics, it would’ve been a stain on the Nobel Prize rather than on him.

Death of World-Renowned Physicist Steven Weinberg

From UT News:

In 1967, Weinberg published a seminal paper laying out how two of the universe’s four fundamental forces — electromagnetism and the weak nuclear force — relate as part of a unified electroweak force. “A Model of Leptons,” at barely three pages, predicted properties of elementary particles that at that time had never before been observed (the W, Z and Higgs boson) and theorized that “neutral weak currents” dictated how elementary particles interact with one another. Later experiments, including the 2012 discovery of the Higgs boson at the Large Hadron Collider (LHC) in Switzerland, would bear out each of his predictions.

Weinberg leveraged his renown and his science for causes he cared deeply about. He had a lifelong interest in curbing nuclear proliferation and served briefly as a consultant for the U.S. Arms Control and Disarmament Agency.

Why Neoliberalism Needs Neofascists

Prabhat Patnaik in Boston Review:

It has been four decades since neoliberal globalization began to reshape the world order. During this time, its agenda has decimated labor rights, imposed rigid limits on fiscal deficits, given massive tax breaks and bailouts to big capital, sacrificed local production for multinational supply chains, and privatized public sector assets at throwaway prices.

The result today is a perverse regime defined by the free movement of capital, which moves relatively effortlessly across international borders, even as free movement of the people is ruthlessly controlled by a sharp increase in income inequality and a steady winnowing of democracy. No matter who comes to power, no matter what promises are made before elections, the same economic policies are followed. Since capital, especially finance, can leave a country en masse at extremely short notice—precipitating an acute financial crisis if its “confidence” in a country is undermined—governments are loath to upset the status quo; they pursue policies favorable to finance capital and indeed demanded by it. The sovereignty of the people, in short, is replaced by the sovereignty of global finance and the domestic corporations integrated with it.

This abridgment of democracy is usually justified by political and economic elites on the grounds that neoliberal economic policies usher in higher GDP growth—considered the summum bonum after which all policy should aim. And indeed, in many countries, especially in Asia, the neoliberal era has ushered in noticeably more rapid growth than under the earlier period of dirigisme. Such growth scarcely benefits the bulk of the people, of course: in fact, neoliberal policies are even more highly associated with the growth of income inequality than with the growth of GDP. (Even International Monetary Fund economists Jonathan D. Ostry, Prakash Loungani, and Davide Furceri concede this point in their 2016 article “Neoliberalism: Oversold?”) But neoliberals have sold a powerful response to this objection: a rise in income inequality should be considered an acceptable price to pay for more rapid growth, for it still might mean an absolute improvement in the conditions of the worst off. The fundamental ideological conceit of neoliberalism has been that growth will lift all boats, even if some boats rise much more than others.
