Mayumi Inaba at the Paris Review:

It was the end of summer, 1977. At least I think it was late summer. I found a cat, a little ball of fluff. A teeny-tiny baby kitten.

Her face was the size of a coin, and was split by her huge wide-open mouth as she hung suspended in the dark. She was stuck inside the fence of a junior high school on the banks of the Tamagawa River in the Y. neighborhood of Fuchū City in western Tokyo. In which direction was the wind blowing that night? It was most likely a gentle breeze blowing up to my house from the river. I’d followed her cries as they carried on this breeze. At first, I searched the gaps in the hedge around my house and among the weeds of the empty plots on my street. But her cries were coming from high up, not low down. I looked up and suddenly saw a little white dot.

The large expanse of the school grounds was shrouded in the dim light. Before me was a high fence separating the road and the school. Somebody must have shoved the kitten into the fence. She was hanging so high up that even on tiptoe I could barely reach her as she clung on for dear life.

Shelby Bradford in The Scientist:

Cellular communication is vital for passing information to neighboring cells. One key messenger in this process is an exosome, a nanosized particle that buds off from a progenitor cell, carrying molecular cargo. Because these small, cellular vehicles carry contents from their parent cells, exosomes can serve as snapshots for a given population of cells, including tumors.

“If you can sample a vesicle, or any entity, from blood, it gives you a huge advantage, being a low or minimally invasive strategy to monitor cancer or detect cancer,” said David Greening, a biologist who studies extracellular vesicles like exosomes at La Trobe University. One strategy to improve the use of exosomes as cancer biomarkers is to identify surface proteins on these vesicles that reflect their originating tumor.¹ L-type amino acid transporter 1 (LAT1), a surface protein that shuttles large amino acids into the cell, is predominantly associated with cancerous cells and correlates with tumor severity.^2,3   These characteristics made the protein an attractive target for therapeutic intervention, with one LAT1 inhibitor currently undergoing clinical trials.⁴

Tara Cheesman at the Cleveland Review of Books:

In 2021, writer Will Hall began scraping Kevin Killian’s reviews from Amazon’s servers and, thanks largely to his efforts, Semiotext(e) published Kevin Killian: Selected Amazon Reviews in November. The 697-page collection rescues from obscurity some of the over two thousand reviews the poet, playwright, novelist, biographer, editor, critic, and artist posted to the platform from 2003 until his death in 2019. He was a great consumer of books, music, and film but also discussed the odd product. Killian’s reviews can be read as meditations on the objects and media that populated our lives for the first twenty-five years of the twenty-first century. He imbued ordinary items – duct tape, a toaster, a DVD—with personal meaning.

Ben Orlin at Math With Bad Drawings:

I’ve come to see this as a basic dynamic in math education reform: an illusory spirit of consensus. Clearly math education needs more something. But more what?

One popular answer: “more data science.” Let’s renounce all of those fusty, old-fashioned trigonometric formulas. Instead, fill math class with 21^st-century virtues: data visualization, probabilistic thinking, and statistical literacy. This isn’t necessarily about new pedagogy; it’s about new content. It’s about re-centering math class on techniques that will cash out, on skills that students might actually apply.

Another popular answer: “more student-centered.” Let’s banish all tasks mechanical and rote. Instead, fill math class with open-ended puzzles, inquiry-based learning, and creative projects. This isn’t necessarily about new content; it’s about new pedagogy. It’s about re-centering math class on the voices, the ideas, and the ingenuity of the students themselves.

Tim Clare in The Guardian:

I beseech you,” wrote Oliver Cromwell, in his letter to the general assembly of the Church of Scotland, “in the bowels of Christ, think it possible you may be mistaken.” Cromwell’s pungent entreaty is often cited in conversations about the importance of self‑enquiry and the perils of overconfidence. It’s an odd but telling choice, given that he was asking others to question their assumptions, while leaving his own unexamined. He had just purged parliament, overseen the execution of Charles I, and was in Scotland leading an army in a pre-emptive strike. Naturally, he wanted the Scottish forces massing for battle to think again. The obvious retort is: “No. You.”

This is one of several thorny problems philosopher Agnes Callard tackles in Open Socrates, an exploration of Socrates’ “substantive ethics of enquiry”; an approach to knowledge that, she argues, can’t merely be tossed into our usual repertoire of rhetorical flourishes, but rather detonates the bedrock on which we claim to stand: “People will announce, ‘Question everything!’ without noticing they have just uttered not a question, but a command.” The Socratic method is an approach with “colossal ambitions” and not just some antiquated curio we might repurpose to get an edge in business meetings. In fact, its power is so great that we must wield it with great care.

David Hudson at The Current:

The title of a series currently running at New York’s Metrograph through February 1, Delphine Seyrig: Rebel Muse, neatly encapsulates a notion that Beatrice Loayza seeks to reevaluate in a series she’s programmed for the Harvard Film Archive. Loayza notes that Seyrig’s “career tends to be defined along the same narrative: she was a muse to European auteurs like Alain Resnais, François Truffaut, Joseph Losey, and Luis Buñuel before repudiating her goddesslike image and pursuing collaborations that challenged and complicated the feminine persona that made her a star.” The Reincarnations of Delphine Seyrig, opening Friday and running through March 2, “reframes the French-Lebanese actress’s body of work and breaks it out of this before-and-after template.”

Farrah Jarral in The Guardian:

It was over schnitzel and mash that my friend’s Bavarian grandparents decided to call me a “black devil”, chuckling all the while. Breaded chicken has since been my madeleine, taking me back to racially charged moments I’ve not known quite how to interpret. Is it really racist if they didn’t mean to be rude? What if they have dementia? And if racism = prejudice + power, was being called a black devil while I choked down some potatoes even that big a deal, given that I felt in no way disempowered in the company of my tiny, elderly hosts?

In his succinct and bingeable book The Science of Racism, professor of social psychology Keon West begins by acknowledging that society doesn’t agree on even the most basic aspects of racism, let alone its finer points. Indeed, roughly half of Britons don’t believe minorities face more discrimination than white people in various areas of life. Yet far from being a set of hazy, unanswerable philosophical questions, many of the unknowns about racism are empirically testable, especially if researchers design clever studies.

Scientists have disguised tumours to ‘look’ similar to pig organs ― tricking the immune system into attacking the cancerous cells. This ruse can halt a tumour’s growth and even eliminate it altogether, data from monkeys and humans suggest. But scientists say that further testing is needed before the technique’s true efficacy becomes clear. It’s “early days” for this novel approach, says immuno-oncologist Brian Lichty at McMaster University in Hamilton, Canada. “I hope it stands up to further clinical testing,” he adds. The work is described today in Cell¹.

Viral trickery

To devise a strategy against cancer, the authors took a cue from a challenge facing people who receive organ transplants: the human immune system recognizes transplanted organs as foreign objects and tries to eliminate them. This challenge is especially acute for transplanted pig organs, which could supplement the supply of donated human livers, kidneys and more. But human antibodies immediately attach to sugars that stud the surfaces of pig cells, leading to rapid rejection of the transplanted tissue. (Pig organs transplanted into humans are bioengineered to forestall the antibody response.) Immunologist and surgeon Yongxiang Zhao at Guangxi Medical University in Nanning, China, wondered whether he could harness this runaway immune response and direct it against tumours.

Simran Hans at The New Statesman:

Twin Peaks first aired in 1991. A tragic and often frightening mystery, it centred on the violent murder of a beautiful teenage girl in a strange, small town nestled in the mountains of the Pacific Northwest. The protagonist was a handsome FBI agent who drank black coffee and spoke in riddles. There was a lot of spontaneous dancing fuelled by a bizarre, forbidding undercurrent of danger. I didn’t understand it at all. I was gripped. I became obsessed with its images of Americana: desolate diners and roadside dive bars, clanking industrial machinery (the fictional town of Twin Peaks has a sawmill), flanked by jaw-dropping natural beauty.

It was a great introduction to many of the director’s long-standing preoccupations: the rot of evil, the mysteries of desire, parallel worlds and the portals to them. The show featured a curdled nostalgia for the 1950s, the music of Julee Cruise, and contained much discussion of the weather (in 2020, Lynch started publishing charming daily weather reports on YouTube), and music from the 1950s. Like his most beloved and best-known film, the Blue Velvet (1986), it deals with the utter devastation of losing one’s innocence.

Robert Long at Experience Machines:

We’re likely to get confused about AI welfare, and this is a dangerous thing to get confused about.

And even though some people still opine that AI welfare is obviously a non-issue, that’s far from obvious to many scientists working on this the topic who take it quite seriously. As a recent open letter from consciousness scientists and AI researchers states, “It is no longer in the realm of science fiction to imagine AI systems having feelings.” AI companies and AI researchers are increasingly taking note as well.

This post is a short summary of a long paper about potential AI welfare called “Taking AI Welfare Seriously“. We argue that there’s a realistic possibility that some AI systems will be conscious and/or robustly agentic—and thus morally significant—in the near future.

Michael Kay at Undark:

In December, 37 colleagues and I published a paper in Science arguing that mirror bacteria — self-replicating, synthetic cells whose every component exists in its mirror-image form — could indeed pose incredibly grave dangers if successfully created. First, they would likely evade most human, animal, and plant immune system responses because these have evolved to tackle natural bacterial threats, not mirrored ones. That intrinsic resistance could lead to widespread, lethal infections in many species (independent of any other factors that make pathogens dangerous, like toxins they can produce). Second, our world is not overrun with natural bacteria partly because they are kept in check by other organisms, such as viruses and amoebae, that prey on them. To the best of our current knowledge, reversed molecular structures would likely give mirror bacteria significant resistance to these predators, potentially enabling them to grow largely unchecked in a wide range of ecosystems.

We shouldn’t lose sleep, though. Nobody is currently close to creating a full mirror bacterium. No one has even achieved the much simpler feat of creating a natural bacterium from its individual components; doing so in mirror form would be an extraordinarily complex undertaking that could take decades. Our intention in publishing our paper was to kickstart the conversation about the potential risks long before they materialize.

Christoph Heine at Psyche:

We found that people varied meaningfully in the strength of their self-insight motive. While it seems to matter a great deal to some people, others do not care about it that much at all. Perhaps you have noticed this among your friends and colleagues, with some of them being far more self-curious than others.

This led us to wonder what kind of a person has a greater self-insight motive. Is it the spiritual seeker who dresses in linen and practises yoga half of the day, or is it the manager who drives an expensive car and lives in a big house, suddenly experiencing a midlife crisis, asking if there is more to life than this? Of course, these are comical stereotypes so we couldn’t answer those exact questions. However, we did give our participants some established personality questionnaires and looked to see how other aspects of personality correlated with their scores on the self-insight motive questionnaire. Rather than throwing a bunch of statistics and correlations at you, I will tell you what we found out about the typical self-insight motivated ‘persona’. Think of it as the kind of profile that marketing folks often create to imagine their typical customer. Just remember, this is a major oversimplification of what were more complex relationships in our data.

We found that the typical persona with strong self-insight motive is a relatively young and educated individual who’s curious, open to new experiences, and concerned about maintaining their close relationships. Picture someone who constantly seeks ways to improve themselves. Finally, we also found that part of the persona is wanting to be admired by others.

Martin Arnold and Lee Harris in the FT:

The world’s financial stability watchdog has warned that disasters caused by climate change are increasingly likely to trigger broader panic in financial markets.

The world breached 1.5C of warming above preindustrial levels for the first time last year, raising the prospect of more environmental disasters.

The Financial Stability Board said the financial damage of climate shocks such as floods, droughts, fires or storms could cause a broader pullback in lending and downturn in investor confidence.

“Banks could reduce lending, including for recovery to already vulnerable households and corporates,” the body, which brings together the world’s central bankers, ministers and regulators, said. “There could also be an abrupt, broad-based repricing of climate-physical risk, as the expectation of larger future losses are incorporated into current prices and impact sectors and jurisdictions not currently directly affected by disasters.”

The report comes amid broader concerns about the capacity of the insurance sector to cover losses associated with climate change following devastating fires in Los Angeles that are estimated to have caused tens of billions of dollars’ worth of damages.

Masayuki Morikawa in Vox EU:

With the rapid diffusion of artificial intelligence (AI), its impacts on productivity and the labour market have attracted attention. Many studies have been conducted on the impacts of industrial robots on productivity (e.g. Graetz and Michaels 2018, Kromann et al. 2020, Cette et al. 2021, Dauth et al. 2021) due to the availability of International Federation of Robotics (IFR) data on robot utilisation by country and industry. However, the quantitative impact of AI on productivity is not yet well understood, mainly due to a lack of statistical data on the use of AI.

Recently, several studies have reported findings from randomised experiments on specific tasks in which AI has a large positive effect on productivity (e.g. Brynjolfsson et al. 2023, Kanazawa et al. 2022, Noy and Zhang 2023, Peng et al. 2023). These studies are valuable contributions that reveal the causal effect of AI on productivity, but it is impossible to infer macroeconomic impacts from these results because the studies only cover the very narrowly defined tasks of customer support, taxi driving, writing tasks, and software programming.

Acemoglu (2024) estimates the medium-term effect of AI on productivity in the US as the percentage of tasks affected by AI multiplied by task-level cost savings based on these existing task-level studies. According to his study, the macroeconomic impact of AI is non-negligible but small, with a cumulative total factor productivity (TFP) increase of less than 0.7%. However, he noted that there is huge uncertainty about which tasks will be automated, and what the cost savings will be.

““Art is the proper task of life,”
………………………. —Nietzsche

Inner Life

Art is an essential part of life. Without its depth
and enrichment, our lives would dry like desert dew
at the break of dawn.

Art enhances human experience by offering beauty,
inspiration, and a means to navigate and interpret the
complexities of being, the magic, the mayhem,
and the throbbing mysteries surrounding us.

In the words of Jean-Luc Godard:
Art attracts us only by what it reveals
of our most secret self.

The creative act is an activity of our inner life,
the dominion of spirit over the material world
serving as a metaphysical lens enabling us
to perceive life with greater depth and nuance.
