Scientists Discover Microbes That Could Revolutionize Plastic Recycling

Molly Enking in Smithsonian:

To tackle the world’s mounting plastics problem, humans may have to use every tool in the arsenal—even microscopic bacteria and fungi. High in the Swiss Alps and the Arctic, scientists have discovered microbes that can digest plastics—importantly, without the need to apply excess heat. Their findings, published this month in the journal Frontiers in Microbiology, could one day improve plastic recycling.

From the Great Pacific Garbage Patch to the tiny microplastics that pervade our drinking waterteafish and blood, it’s no secret that plastic pollution is a big, global issue. Since its production exploded during and after World War II, humans have created more than 9.1 billion tons of plastic—and researchers estimate that less than one tenth of the resulting waste has been recycled.

Ken Jennings Has Some Questions About Death

Sarah Larson in The New Yorker:

In 2003, Ken Jennings was a twenty-nine-year-old software engineer, living in a suburb of Salt Lake City with his wife and young son, when his old college roommate suggested that they try out for “Jeopardy!” A year later, Jennings, a trivia enthusiast who’d grown up watching the show, made it on the air, had a seventy-four-game winning streak, and won more than $2.5 million, becoming the winningest “Jeopardy!” contestant of all time. (He still is: a year and a half ago, Amy Schneider, the second-winningest, won forty consecutive games.) After Alex Trebek, the show’s beloved host, died in 2020, the show endured an uneasy era of temporary hosts and executive blunders. But now Jennings helms the show, in rotation with Mayim Bialik—and “Jeopardy!,” that reliable source of answers-in-the-form-of-a-question comfort, once again feels like it’s in good hands. Jennings is a natural, ably enhancing the game’s inherent charms with warmth and wit, fostering an atmosphere of collegial curiosity. He even manages to make the show’s personal-anecdote segment the least awkward it’s ever been.

In the past two decades, Jennings has also written several books, hopping from subject to subject in the way of a great generalist: there’s trivia, sure, but also comedy, geography, everyday myths, a variety of fact books for kids, and, now, the afterlife. “100 Places to See After You Die” is a gung-ho travel guide to Heaven, Hell, and beyond, as represented by mythology, religion, literature, and pop culture, extending to realms including Narnia, the Outer Planes from Dungeons & Dragons, and the mid-century gag comic “They’ll Do It Every Time.”

At its best, Martin Amis’s fiction broke open the locked door behind which our culture tries to keep its skeletons hidden

Matt Hanson in Quillette:

Maybe one sign of being an important writer is how much attention you receive when you die. Tributes to and remembrances of Martin Amis, who died last week at 73, have been appearing all over the place, like fresh bouquets of sympathy sent to a funeral. I almost found myself lazily inserting the phrase “after a long battle with cancer” to specify the conditions of his demise, but since Amis was famously at war with cliches, this would not do. Amis refused to hide his taste, his opinions, and above all, his style under a bushel, and this is why people loved him on both sides of the Atlantic.

Having Kingsley Amis as a father would be a blessing and a curse for anyone, though Amis generally chose to emphasize the former in his memoirs.

Large Language Models in Molecular Biology

Serafim Batzoglou at Towards Data Science:

Will we ever decipher the language of molecular biology? Here, I argue that we are just a few years away from having accurate in silico models of the primary biomolecular information highway — from DNA to gene expression to proteins — that rival experimental accuracy and can be used in medicine and pharmaceutical discovery.

Since I started my PhD in 1996, the computational biology community had embraced the mantra, “biology is becoming a computational science.” Our ultimate ambition has been to predict the activity of biomolecules within cells, and cells within our bodies, with precision and reproducibility akin to engineering disciplines. We have aimed to create computational models of biological systems, enabling accurate biomolecular experimentation in silico. The recent strides made in deep learning and particularly large language models (LLMs), in conjunction with affordable and large-scale data generation, are propelling this aspiration closer to reality.

Michael Levin: The electrical blueprints that orchestrate life

DNA isn’t the only builder in the biological world — there’s also a mysterious bioelectric layer directing cells to work together to grow organs, systems and bodies, says biologist and Wyss Associate Faculty member Michael Levin. Sharing unforgettable and groundbreaking footage of two-headed worms, he introduces us to xenobots — the world’s first living robots, created in his lab by cracking the electrical code of cells — and discusses what this discovery may mean for the future of medicine, the environment and even life itself.

The Fake News about Fake News

Daniel Williams in the Boston Review:

At the end of the Korean war in 1953, captured American soldiers were allowed to return home. To widespread amazement, some declined the offer and followed their captors to China. A popular explanation quickly emerged. The Chinese army had undertaken an unusual project with its prisoners of war: through intense and sustained attempts at persuasion—using tactics such as sleep deprivation, solitary confinement, and exposure to propaganda—it had sought to convince them of the superiority of communism over capitalism. Amid the general paranoia of 1950s McCarthyism, the fact that such techniques had apparently achieved some success produced considerable alarm. The soldiers had been “brainwashed”—and everyone was vulnerable.

The ensuing panic over mind control stoked a frenzied search for solutions. How could the American public be protected against this new menace? William J. McGuire, a young and ambitious social psychologist, was among those who took up the challenge. McGuire’s big idea was to liken brainwashing to a viral infection. In such cases, post-infection treatment can help, but it is far better to inoculate individuals before they are exposed. Bolstered by a series of experiments that seemed to support his conjecture, McGuire ran with this analogy.

In New Paradox, Black Holes Appear to Evade Heat Death

George Musser in Quanta Magazine:

When an ice cube melts and attains equilibrium with the liquid, physicists usually say the evolution of the system has ended. But it hasn’t — there is life after heat death. Weird and wonderful things continue to happen at the quantum level. “If you really look into a quantum system, the particle distribution might have equilibrated, and the energy distribution might have equilibrated, but there’s still so much more going on beyond that,” said Xie Chen, a theoretical physicist at the California Institute of Technology.

Chen, Swingle and others think that, if an equilibrated system looks boring and blah, we’re just not looking at it in the right way. The action has moved from quantities that we can see directly to highly delocalized ones that require new measures to track. The favorite measure, at the moment, is known as circuit complexity. The concept originated in computer science and has been appropriated — misappropriated, some have grumbled — to quantify the blossoming patterns in a quantum system. The work is fascinating for the way it brings together multiple areas of science, not just black holes but also quantum chaos, topological phases of matter, cryptography, quantum computers, and the possibility of even more powerful machines.

They Call Me Bruce

Oliver Wang at The Current:

In the conventional canon of Asian American cinema, you’re unlikely to find They Call Me Bruce mentioned. This is in spite of the fact that it arrived right after Wayne Wang’s lauded debut, Chan Is Missing (1982), as arguably the second Asian American feature to ever gain theatrical distribution (and probably the first to turn a substantial profit). This makes its absence from the canon all the more curious, and both They Call Me Bruce and its primary creators are overdue a reconsideration.

Like their film, Elliott Hong and Johnny Yune are fascinating but largely forgotten. Hong, in particular, is an enigma; it’s hard to find much information about the Korean American filmmaker, though he directed several features—mostly independently produced action movies—beginning with Kill the Golden Goose (1979). They Call Me Bruce’s B-movie trappings—cheap production design, amateur action choreography—tend to fall somewhere between “so bad they’re good” and “just plain bad,” but it’s important to think about the film as a reflection of both its era and its limited budget, both of which have contributed to its neglect.

The Secret Sound of Stax

Burkhard Bilger at The New Yorker:

It wasn’t the singing; it was the song. When Deanie Parker hit her last high note in the studio, and the band’s final chord faded behind her, the producer gave her a long, appraising look. She’d be great onstage, with those sugarplum features and defiant eyes, and that voice could knock down walls. “You sound good,” he said. “But if we’re going to cut a record, you’ve got to have your own song. A song that you created. We can’t introduce a new artist covering somebody else’s song.” Did she have any original material? Parker stared at him blankly for a moment, then shook her head.

No. But she could get some.

Parker was seventeen. She had moved to Memphis a year earlier, in 1961, to live with her mother and stepfather, and was itching to get out of school and start performing. She was born in Mississippi but had spent most of her childhood with her aunt and uncle in Ironton, Ohio, a small town on the Kentucky border.

Thursday Poem

Discontinuous Poems

The frightful reality of things
Is my everyday discovery.
Each thing is what it is.
How can I explain to anyone how much
I rejoice over this, and find it enough?

To be whole, it is enough to exist.

I have written quite a number of poems
And may write many more, of course,
Each poem of mine explains it,

The Kansas Lek Treks Prairie-Chicken Festival

Alex Ransom at n+1:

Birders are a funny bunch, mostly—at this festival, anyway—white, older-aged, and of a delightfully inefficient temperament. In general, they talk and move at a relaxed pace, and are eager to dedicate long moments of their lives to matters that many people simply whisk past. On a geology tour my mom and I took on our third day in Hays, the group revolted and made the guide turn the van around just to take pictures of a flock of turkeys. Later, about a half hour was spent on a quiet debate over whether a falcon in a far-off tree was a kestrel or a much more uncommon merlin. I listened to a man trying in vain for several minutes to describe the position of the falcon to the woman next to him: “It’s in the backmost tree, up there on the white branch. There are a lot of light branches. But no! There’s only one white branch.” Over the course of the trip, time seemed to slow down to match the geologic scale suggested by the ancient mating rituals of the prairie chickens and the landscape that surrounds them: sprawling fields of grass punctuated by chalk formations left over from Kansas’s past beneath the Cretaceous-era Western Interior Seaway.

France on Trial: The Case of Marshal Pétain

Munro Price at Literary Review:

On 23 July 1945 the 89-year-old Marshal Philippe Pétain, until recently head of the French state, went on trial for his life before a specially convened High Court in Paris, accused of attacking national security and collusion with Nazi Germany amounting to treason. For four years, from the fall of France to the liberation, he had steered the Vichy regime created from the wreckage of defeat into collaboration with the new continental hegemon, Adolf Hitler. Now, after eight months of wandering to escape the advancing Allies through eastern France to the castle of Sigmaringen in Germany and finally to Switzerland, he was in the custody of General de Gaulle’s provisional government.

Pétain’s trial was about much more than the fate of one extremely elderly man. It was newly liberated France’s first opportunity to confront the traumas it had endured from May 1940 to August 1944: the catastrophic military defeat by Germany, the signing of the armistice, the dissolution of the Third Republic and its replacement by the authoritarian Vichy state, the deportations of Jews and the increasingly bloody civil war between the collaborationist regime and the Resistance.

Epictetus: The Complete Works, Reviewed

Emily Wilson in the London Review of Books:

The​ first-century Stoic philosopher and teacher Epictetus was an enslaved person who succeeded in getting an education and, eventually, his freedom. Images of freedom, slavery and self-belonging (oikoiesis) recur in his teaching. ‘A slave is always praying to be set free,’ he writes. He evokes the horrors of enslavement by describing the suffering of caged animals and birds that refuse to eat in captivity and starve to death, though he also occasionally repeats a conventional set of ideas about slavery, claiming, for example, that runaway slaves are ‘cowards’, and that none of them ever dies of hunger. Slavery powered the Roman Empire; in the first century ce, between 10 and 20 per cent of the population were enslaved at any one time. But Epictetus was not an abolitionist in a political sense. Like other ancient philosophers, he assumed that slavery was normal and would always exist. He never suggests that those who claimed to own their fellow human beings were committing a moral evil. His aim was to free others from the ‘tyrannic sway’ not of literal enslavers, but of the emotional disturbance caused by false belief.

The complicated, ever-changing, millennia-long relationship between insects and humans

Ian Rose in JSTOR Daily:

For at least the last 400 million years, insects have ruled the world. The first insect fossils are nearly twice as old as the oldest dinosaur. They were the first animals to fly, and that adaptation helped them to spread to every corner of the planet. They survived four of the five mass extinctions in Earth’s history. Then, a mere 200,000 years ago, a new species appeared in East Africa and started to spread over the surface of their planet. In a geologic blink, modern humans were everywhere, hunting and farming and changing the world to fit our needs and desires. It was inevitable that these two dominant animals would come to affect each other in profound ways, both positive and negative.

For most of our history as a primarily hunter-gatherer and then agricultural species, insects were a natural force on par with the weather. We could no more summon their benefits or hold back their ravages than we could start or stop the wind. So, we lived with them, and adapted to them, as they did to us. Our relationship status has always been complicated, but insects fall into three major roles in terms of how they interact with humans—providers, destroyers, and vectors of disease.

ChatGPT’s secret reading list

Adam Rogers in Business Insider:

The inner workings of the large language models at the heart of a chatbot are a black box; the datasets they’re trained on are so critical to their functioning that their creators consider the information a proprietary secret. So Bamman’s team decided to become “data archaeologists.” To figure out what GPT-4 has read, they quizzed it on its knowledge of various books, as if it were a high-school English student. Then they gave it a score for each book. The higher the score, the likelier it was that the book was part of the bot’s dataset — not just crunched to help the bot generate new language, but actually memorized.

In a recent preprint, meaning it hasn’t been peer reviewed yet — the team presented its findings — what amounts to an approximation of the chatbot canon.
