Welcome to the top o’ the week: it’s Monday, May 19, 2025, and National Devil’s Food Cake Day (remember, there’s also Angel Food Cake). The origin of the name is obscure, for this is simply a chocolate cake, usually darker than a normal one and frosted with chocolate, comme ça:

Wikipedia says this:

The name probably had several sources of inspiration, including the culinary term deviled to describe flavorful foods like deviled eggs and the contrast of this dark, dense, flavorful cake with the light and airy angel food cake. The name has inspired humorous comments; one of the first printed recipes declares it to be “Fit for Angels”, and another early recipe recommends topping it with divinity frosting.

But if you look up the culinary term deviled, you get “grilled with a piquant sauce”!

It’s also World Family Doctor Day, but not much else.

Readers are welcome to mark notable events, births, or deaths on this day by consulting the May 19 Wikipedia page.

Da Nooz:

*Joe Biden has been diagnosed with an aggressive form of prostate cancer, and it’s metastasized to his bones. As they said on the news last night, “It’s not curable, but it’s treatable.”

The diagnosis came after Mr. Biden reported urinary symptoms, which led doctors to find a “small nodule” on his prostate. Mr. Biden’s cancer is “characterized by a Gleason score of 9” with “metastasis to the bone,” the statement said.

The Gleason score is used to describe how prostate cancers look under a microscope; 9 and 10 are the most aggressive. The cancer is Stage 4, which means it has spread.

“While this represents a more aggressive form of the disease, the cancer appears to be hormone-sensitive which allows for effective management,” according to the statement from Mr. Biden’s office, which was unsigned. “The president and his family are reviewing treatment options with his physicians.”

This is very sad to hear, especially given that two of his children also died, one of brain cancer and the other in an accident that also killed Biden’s first wife. He’s also had two dangerous brain aneurysms.  The guy has been through a lot.

*Boss vs. Boss: Trump is trying to get Bruce Springsteen to shut up. It isn’t working (article archived here).

President Trump warned Bruce Springsteen to “keep his mouth shut” until he gets back to the U.S. The rock icon is showing no signs of backing down, delivering a fiery performance from a stage in this city Saturday that reflected the stark political divide in America.

Springsteen echoed earlier criticism of the Trump administration Saturday, saying a “rogue” government was rolling over U.S. lawmakers and institutions designed to keep authoritarianism in check.

“Things are happening right now that are altering the very nature of our country’s democracy,” Springsteen told the audience. To drive the point home, he dedicated one of his songs to our “Dear Leader,” an allusion to the honorific set aside for former North Korean ruler Kim Jong Il.

A similar broadside last week prompted Trump to take aim at Springsteen in a social-media post: “I see that Highly Overrated Bruce Springsteen goes to a Foreign Country to speak badly about the President of the United States. Never liked him, never liked his music, or his Radical Left Politics and, importantly, he’s not a talented guy.”

The escalating confrontation between the president and Springsteen is part of a broader clash between Trump and some pop-culture icons that goes back to the president’s first term. Trump has repeatedly assailed Taylor Swift, who endorsed Kamala Harris in last year’s election but hasn’t engaged in the sort of sharp-tongued criticism delivered by Springsteen.

Trump lashed out at Swift in a separate post Friday: “Has anyone noticed that, since I said ‘I HATE TAYLOR SWIFT,’ she’s no longer ‘HOT?’”

. . . . few artists have been as blunt as Springsteen, who for decades has cast himself as a champion of the working class and, in recent decades, has regularly campaigned with Democratic Party presidential candidates.

Still, Springsteen has generally been able to straddle the partisan divide in America. His 1984 anthem “Born in the U.S.A.” was widely embraced by Republicans including Ronald Reagan, despite its lyrics’ searing criticism of U.S. foreign and domestic policy. Springsteen also counts New Jersey’s former Gov. Chris Christie, a Republican and longtime presidential aspirant from Springsteen’s home state, among his biggest fans.

Still, despite Springsteen’s support, the Democratic Party has seen its longtime strength among blue-collar workers eroded by the rise of Trump. The president has transcended his own gilded upbringing to become a hero to many voters across the Rust Belt states that Springsteen has made a career of singing about—including Youngstown, a working-class city in Ohio that was the eponymous subject of one of the songs Springsteen played on Saturday.

Keep on speaking your mind, Bruce!  Trump can’t do anything to you, because you have freedom of speech. It’s clear that Trump has no ability to ignore criticism, but always answers it with juvenile name-calling.

*From the NYT: “Hollywood couldn’t imagine a star like this one” (archived here). Who is the star? Why, it’s Desi Arnaz from “I Love Lucy”, a show I regularly watched as a kid.

Seventy-five years ago, a fading redheaded movie star and her itinerant bandleader husband were searching desperately for a way to save their careers — and their marriage. She was starring in a network radio show in Hollywood and he was a musician on the road all the time, so they rarely saw each other. In their 10 years together, she’d already filed for divorce once, and was nearing her wits’ end.

The movie star was Lucille Ball and the bandleader, of course, was Desi Arnaz. In 1950, a glimmer of hope appeared for the couple: CBS intended to transfer Ball’s radio show, “My Favorite Husband,” to the untested new medium of television. But there was a problem: Ball wanted to make the move only if Arnaz — who’d helped start the conga dance craze in nightclubs in the 1930s and fueled America’s demand for Latin music after World War II — could play that husband on TV. The network and prospective sponsors believed the public would never accept a thick-accented Latino as the spouse of an all-American girl. “I was always the guy that didn’t fit,” Arnaz would later tell Ed Sullivan.

Arnaz, a Cuban immigrant and self-taught showman, had an idea: The couple would undertake an old-fashioned vaudeville tour of major cities around the country. He and Ball would demonstrate the real-life chemistry that he knew would click with Americans if they only had a chance to see the act.

Miracle of miracles, it worked. Critics and audiences from coast to coast raved at the couple’s onstage antics, as Lucy clowned with a battered cello while Desi sang and drummed his heart out. A.H. Weiler of The Times pronounced the pair “a couple who bid fair to become the busiest husband-and- wife team extant.” Soon enough, they were.

. . . Arnaz’s differences — the very elements that made network chiefs hesitant to feature him — became his greatest strengths, as his charming portrayal of the solid, bread-winning paterfamilias of an intermarried family broke new ground in television and made Ricky Ricardo a beloved figure to the 30 million people who watched his show each week. He was the one TV star who did not look or sound like any other — he was forever telling Lucy she had some “’splainin’ to do” — an immigrant who became the all-American man. The show’s sponsor had been so skeptical about Arnaz’s appeal that the contract with Desilu stipulated that Ricky could sing only if it was absolutely necessary to the plot. The audience’s near-immediate embrace of Arnaz and his music made that a moot point and the clause was eventually dropped.

The title of the inside article is “What Desi Arnaz could teach Hollywood today,” and the lesson is obvious:

He looked and sounded nothing like the preconceived notion that the entertainment business had of a successful star. So he changed the way Hollywood did business, and whom we can imagine as stars. Anyone who can’t understand that has some ’splainin’ to do.

Indeed (and remember Fred and Ethel?)!  I loved that show and knew none of the above. Here’s a short clip of scenes featuring the pair:

*On his Substack site, the well-known physician and writer Eric Topol discusses the first human to be treated for genetic disease with in vivo “CRISPR 2.0 personalized genome editing.” (h/t reader Gingerbaker).  The genetic disease was “severe carbamoyl-phosphate synthetase 1 deficiency, a disease with an estimated 50% mortality in early infancy.”  After determining the infant’s defects, they developed an infusion that was targeted at the prcise base pair that was defective, and then gave it repeatedly to the one-year old. From Topol’s report:

This was unique in many respects. KJ Muldoon was born in August 2024 with lethargy, rigid muscles and other worrisome symptoms. Genome sequencing revealed this was due to a severe urea-cycle disorder that leads to accumulation of ammonia and death in about half of infants affected, and short of death, the high levels of ammonia cause lethargy, seizures, coma, and brain damage. The disease-causing gene was CPS1 (carbamoyl-phosphate synthetase 1 deficiency), a 1 in a 1.3 million births genetic (ultra-rare) disease. KJ was hospitalized and awaited a liver transplant, listed at 5 month of age, if a donor organ became available. In the meantime, therapy consisted of a low protein diet and ammonia lowering (“nitrogen scavenger”) medications.

To get to the basis of KJ’s genomic defect and attempt a cure, the team at Children’s Hospital of Philadelphia (CHOP) and Penn Medicine (led by Drs. Rebecca Ahrens-Nicklas and Kiran Musunuru) sequenced KJ and his parents. The father had a truncating CSP1 variant (Q335X) and the mother a different variant, E714X). They developed an adenosine base editor (called K-abe, schematic below) to specifically correct KJ’s defective CPS1 gene. The approach taken was particularly rigorous and comprehensive. Within 6 months they tested the editor in cells with the genomic variants, in mice (bred to specifically have KJ’s CPS1 mutation), in non-human primates, and got FDA approval to give it. It was administered intravenously using delivery via mRNA + nanoparticles beginning in February 2025 and then with 2 subsequent doses. The base editor used was directed against the paternal mutation (a G→A stop variant) at the Q335X site of the CSP1 gene.

What is missing to date is a liver biopsy, due to risk to the infant, to prove the targeted CSP1 editing. There is also lacking evidence of a cure—”just” a reduced need for medications and the restrictive diet. But also encouraging is that KJ is now reaching developmental milestones and although he sustained two viral infections, both were without an ammonia crisis. Further doses of the base editor can be administered with the mRNA approach (rather than a virus vector that can induce an immune response). Regarding uncertainties, we also don’t know about the durability of the editing, any mosaicism impact (only some liver cells edited), and the potential of any off-target effects (rigorously assessed in the 6-months sprint of lab experiments but not yet in KJ).

It seemed to work, though of course fixing a genetic disease by changing some of the cells isn’t guaranteed to be a permanent fix, as there are other, unfixed cells that keep replicating. I’m not sure whether the infant will require lifelong infusions, or whether the disease has bad effects only in infancy, but it’s remarkable that you can target liver cells and change a single base pair in the DNA (out of 3 billion bases) in an attempt to cure a genetic disease. Topol adds this:

This case of KJ represents a human first—-personalized, N-of-1 genomic intervention with base editing (CRISPR 2.0), in the body (in vivo), to directly fix a pathogenic (disease-causing) gene mutation. This bespoke intervention was accomplished in a remarkably compressed timeline that included rigorous assessment in cell and animal models, along with regulatory approval to proceed. It embodies something in medicine we have not and could not have done previously. It involved a dedicated team at CHOP and Penn and collaborators spread out around the world.

There are many specific aspects of the case that deserve attention. The fact that this work culminated from many years of NIH supported research, including the current report, at a time when we’re seeing profound and indiscriminate cutting of such funds

Here’s the paper from NEJM:

There is a lot more of this to come, and it’s amazing that we’re living in an age in which gene editing (which arose as a fortuitous byproduct of pure scientific curiosity about hot-spring bacteria) can be used to ameliorate or cure genetic diseases.

*The Times of Israel reports that the body of Hamas leader Muhammad Sinwar, the target of an attack about a week ago, has (according to a Saudi report) been found in a tunnel in Gaza. The third Sinwar brother, Zakaria, was killed by an airstrike on Sunday night. (Some time ago Yahyta Sinwar, the leader of Hamas, was also killed by the IDF).  The IDF reported the strike, but they don’t take a kill for granted unless they’re sure, and I’m accepting this Saudi version.

A series of Israeli airstrikes last week killed Muhammad Sinwar, the de facto commander of Hamas in Gaza, according to reports on Sunday that said his body was found in a Khan Younis tunnel.

Muhammad Sinwar was the younger brother of the former Hamas leader in Gaza, Yahya Sinwar, who was killed by the IDF in southern Gaza last October.

According to a separate report, Zakaria Sinwar, another brother, was killed in an Israeli airstrike on Saturday night. [JAC: I’ve heard rumors that Zakaria was in the morgue, showed signs of life, and has been taken to the hospital. Stay tuned.]

A series of Israeli airstrikes last week killed Muhammad Sinwar, the de facto commander of Hamas in Gaza, according to reports on Sunday that said his body was found in a Khan Younis tunnel.

The strikes that reportedly killed Muhammad Sinwar on Tuesday targeted an underground command compound below the European Hospital where he was believed to have been sheltering.

The IDF later bombed the area several more times, in an apparent attempt to prevent anyone from approaching the tunnel.

According to the Saudi channel Al-Hadath, his body was recently recovered along with the remains of 10 of his aides.

The report said that there was evidence that the commander of the Rafah Brigade in Hamas’s military wing, Mohammad Shabana, was also killed in the strike.

What effect, if any, these strikes will have on Hamas remains to be seen. After all, some predicted that Hamas would give up after Yahya Sinwar was killed. It did not. But it’s clear that Israel’s big push now is designed to finish the job, and may have led to the proposal in the next item.

*In addition, Israel and the Qataris (and, “indirectly,” Hamas) are pondering one war-ending plan that would return all the hostages (dead or alive) and get Hamas to give up:

Prime Minister Benjamin Netanyahu’s office says Israel’s hostage negotiation team in Doha is exhausting “every possibility” for a deal, including a potential agreement that would see the end of fighting, in an apparent shift in approach.

The PMO says that the team is working toward the possibility of either US special envoy Steve Witkoff’s proposal for a short-term ceasefire and limited hostage exchange, or an agreement to end the war through a comprehensive release of all hostages in Gaza and the complete surrender and exile of Hamas.

“Under the prime minister’s direction, even at this hour, the negotiating team in Doha is working to exhaust every possibility for a deal — whether according to the Witkoff outline or within the framework of ending the war, which would include the release of all hostages, the exile of Hamas terrorists, and the disarmament of the Gaza Strip,” writes the PMO in a statement.

. . . . Israel has consistently said that the war will not end without the destruction of Hamas as a military and governing power. Netanyahu has previously insisted on only agreeing to a temporary ceasefire of roughly 45 days, which would begin with Hamas releasing about 10 hostages.

Will Hamas give up and go into exile? This doesn’t seem likely, as they always say they value death more than the IDF values life, and many truly believe that if they die while “resisting,” they will go to heaven and get those virgins. But surely some members of Hamas don’t want to die. See also this archived article about the IDF’s “excpanded ground operations” in the NYT.

Another instance of deplatforming tweeted by Nicholas Christakis at Yale. Salman Rushdie was scheduled to give the commencement speech at Claremont-McKenna College. From the link in the tweet:

The cancellation came as student and local Muslim advocacy groups called the author’s presence “disrespectful” after he said pro-Palestinian protests across college campuses were akin to supporting “a fascist terrorist group,” The Guardian reported last year.

“I’m surprised, relieved and happy,” Claremont Colleges Muslim Students Association president Kumail Afshar said about Rushdie’s decision.

Rushdie, an Indian-born British and American atheist, was forced into hiding by the outrage over his 1988 novel The Satanic Verses, in which he suggests Islam’s Prophet Muhammad may have entertained polytheism.

The College supported Rushdie, but I suspect he was scared of being attacked again:

Spacecraft orbiting Mars can reveal small features on the planet's surface, but there are only so many things you can see from above. When a meteor strikes the surface of Mars, it can excavate sub-surface material, allowing scientists to study what lies beneath. Researchers have simulated various impacts on Mars, changing the sub-surface material from bedrock to water-ice glaciers, and then calculated what should be visible after an impact, enabling new science.

Today is Day 11 since Esther’s ducklings hit the water, and it’s time to share some photos and video of her, Mordacai (yes, he’s still here) and their brood.

But first, we were lucky enough to get a video, courtesy of an undergraduate, of the ducklings hatching underneath Esther, whose nest, you may recall, was on the ground. This video was taken on May 6, and you can see, peeping from beneath her, newly hatched ducklings. One who just hatched is still wet from the egg, while others, a bit older are dry. There were seven total, though one disappeared the first night to unknown causes.  Be sure to listen to the gasps from the students as they see the babies: “Holy cow!”  “Oh, my god!” (I’ve shown this video before, but put it up again because it’s lovely.)

They stay under mom for the first day, and hit the water the second day, which they took to. . . well, like ducks to water. (See the photo of their first moment in the water here.)

The remnants of Esther’s rather crude nest; you can see the broken eggshells. Despite being a rather incompetent nest-builder, she’s a great mom in the water.

Click on all photos to enlarge them.

It wasn’t long before Esther took them on a tour of the pond so they could learn the surroundings.  They quickly learned to use the duck ramps so they could get out of the water and dry off in the sun. In this photo she looks proud to me, but of course that’s anthropomorphizing.

This looks like the brood of five when one duckling went missing for a day but, mirabile dictu, returned the next day. I have no idea where it was.

This video shows how they swim purposefully with the mother when Esther has decided to swim to a definite place. At other times she lollygags about and the ducklings spread out over much of the pond.

The whole family on the edge of the pond (they went up via the ramp). The faithful Mordecai is standing guard to the right.

Esther and the babies. It’s warm beneath her: I’m told about 100°F.

Mom and most of the babies napping:

Mordecai napping. He is an excellent dad, driving off alien drakes who try to make time with Esther. You can see that he’s well fed by his belly hanging over the edge. We call such individuals “Dali ducks.”

Here’s a video of the ducklings (7) discovering that there are rocks they can climb on, get some sun, and dry off.

Finally, a passel of ducklings (the formal name for such a group is a “flock,” a “waddling”, or a “raft”).  Needless to say, on a nice day the pond is crowded with onlookers oohing and aahing over the babies and taking pictures of them. Right now, in the absence of any turtles or fish, the ducks and ducklings are the major attraction at Botany Pond:

Here’s the comedy bit from Bill Maher’s latest “Real Time”, and it’s called “New Rule: Don’t be a hypocrite.”

A few examples:

Trump touting electric cars (Teslas) after he appropriated Elon Musk.

Republicans buying Tesla cybertrucks after most saying they’d never buy an electric truck

The American Academy of Pediatrics reversing its position on getting kids into schools after Trump agreed with them

Republicans denigrated Michelle Obama’s program, “Let’s get American healthy again”, simply because it was from Michelle Obama.

Republicans now love Russia (so Maher said) when it was previous their nightmare country.

There are lots of examples of people accepting or rejecting programs or propositions simply because of who advocated them, and that is a form of hypocrisy. Most of his examples are anti-Republican, so take that, those people who consigned Maher to hell because he had dinner with Trump and found him a gracious host. (That denigration of Maher by those who dislike Trump—and those people include Maher—is itself a form of hypocrisy. If you dislike Trump, it’s impossible to ever find him gracious.)

As he says, we should “not to automatically rush to the opposite viewpoint based solely on who said it. But until we get to where we can do that, and I just hope the Democrats come out strongly next week for a dictatorship, coal mining, and making pot illegal.”

It’s a plea for comity, but nobody seems to be in that mood these days.

If you’ve read about the various pro-Palestinian and anti-Israel protests across American campuses, one thing you’ll notice is a general reluctance to punish demonstrators when they violate university rules. Of course protests are usually fine if they conform to First Amendment principles (though some schools don’t hold those principles), but they’re never fine when they violate campus rules.  These latter rules are usually called “TPM rules”, meaning that universities can regulate the “time, place, and manner” of demonstrations in a way that doesn’t impede the mission of the institution: teaching, learning, and research.

So at the University of Chicago, for example, we’ve laid out the rules for protests and demonstrations at this website, which gives information about noise levels permitted, building occupancy (not permitted at all) and the like.  In 2024, I gave four examples of pro-Palestinian demonstrators violating University regulations without any punishments meted out. The only sanction levied was a tepid warning to Students for Justice in Palestine that they disrupted a Jewish gathering, a warning that they’d better not do it again or else. . . .

As I always say, rules that aren’t enforced are not rules at all. Even our encampment, which involved several hundred people—both students and outsiders—which was declared in violation of university rules, was dismantled by the university police, but none of the demonstrators faced any punishment.

Is it any wonder, then, that the anti-Israel demonstrators feel empowered to break any campus rules they want? And they did—two weeks ago when the pro-Pals, a consortium called “UCUP”, for “UChicago United for Palestine” held a week of demonstrations commemorating last year’s encampment, which, not coincidentally, also included Alumni Weekend. (One wonders what mindset thinks that these loud and obnoxious intrusions will change peoples’ opinions.)

At any rate, the Chicago Maroon, which loves nothing more than an anti-Israel demonstration, had an article about a week of protests that included several violations of University rules, all of which seem to have been unpunished. Oh, well, there’s one exception: the police confiscated one megaphone being used illegally. I suppose they arrested it for “excessive loudness.”

Click below to read the article. I’ve bolded the bits where illegal actions went unpunished. The cops and deans-on-call showed up, but the former are constrained by the administration and can’t take action without permission from above, and deans-on-call are, to me, a joke; mere observers who can’t enforce anything and barely want to report anything. In fact, some of the deans-on-call are blatantly pro-Palestinian, and so can’t be objective. Here’s a photo of the “watermelon” (Palestinian colors) fingernails of one of those deans-on-call taken by a student during the encampment last year:

I’ll give some excerpts showing how the U of C ignores violations, as well as giving the article’s introduction. Click headline below to read; unpunished violations are in bold.

Marking the one-year anniversary of the 2024 pro-Palestine encampment, UChicago students and community members launched a week-long protest and installation outside Swift Hall. The students, organized as the “Popular University for Gaza,” called for solidarity with Palestine and the divestment of University funds from institutions tied to Israel.

Between Monday, April 28, and Friday, May 2, the group held teach-ins, workshops, and demonstrations—some resulting in confrontations with the University of Chicago Police Department (UCPD) and deans-on-call—as they sought to maintain public pressure on University leadership.

Shortly after 1 p.m. on April 28, protesters gathered on the quad outside of Swift Hall, raising a banner reading “Free Palestine, Bring the Intifada Home.” UCPD officers and deans-on-call observed from a distance as the group began a series of chants over a megaphone. Deans repeatedly informed the protesters that they were in violation of University policies regulating the use of amplified sound on campus.

Did anybody stop the violations? Are you kidding me?

Around an hour and a half into the demonstration, the UCPD officers and deans-on-call requested identification from those who had been using megaphones. The protesters initially locked arms to prevent possible arrests, with the crowd gradually dispersing as officers continued to ask for identifying information.

And again it seems as if the protestors, who are obliged to provide identification, did not do so; nor did the cops take any IDs.

Here’s a protestor waving a Houthi flag; photo by Grace Beatty.  Love that AK-47! Note the covered faces of the protestors, indicating two things: they are cowards who don’t want to be identified, and they are not enacting civil disobedience, whereby you break a law considered immoral and voluntarily take the punishment.

On Thursday they arrested. . . .a megaphone:

Two UCPD officers, along with several deans-on-call, gathered to observe the protest.

As protesters continued to chant, UCPD officers chased after demonstrators and confiscated at least one megaphone. The demonstration, which took place after 1 p.m., was again in violation of University policy regarding amplified sound. An unidentified protester flew a flag identifying with the Houthi movement in Yemen; one UCPD officer was overheard saying “As long as they’re holding [the flag], it’s free speech.”

The cop is right about free speech; our campus police are well aware of what is a violation and what is not. But they cannot move against real violations without permission of the administration.

Finally, although again this is legal, they heckled the President and Provost. Not THAT is going to change their minds!

Here’s President Alivisatos being heckled as he walks to the alumni tent. He kept his cool and did not respond. And you have to hand it to the heckler that he didn’t cover his face. (This was published on the UC United Instagram page.)

So the week was a mixture of legal and illegal activities by the protestors, but the only thing arrested was a megaphone.

Below you see a poster in the Quad. If you know what “Intifada” means, it’s a term in Arabic for “shaking off” and has come to mean “shaking off the Jews”, i.e., killing them. These are really congenial sentiments.

I’m not sure whether the students had permission to post such a banner, but even if they did the sentiments surely create a hostile climate for Jewish students:

Photo by Nathaniel Rodwell-Simon

These demonstrations used to bother me more, especially their implicit calls for genocide of Jews (the poster above and the “From the river to the sea. .  ” chants), but now that Hamas is losing, and the University of Chicago has made it clear that it will not divest from Israel, these demonstrators strike me as pathetic, cosplaying as Houthis and members of Hamas.  Surely a large moiety of them are antisemitic, and it’s okay to do that so long as you don’t create a climate inimical to the participation of Jewish students at the University.  Do we have such a climate? You’d have to ask the Jewish students, but some of them have, I’ve heard, said “yes.” I know some of them won’t wear their Stars of David necklaces in a way that make them visibly Jewish.

I wish only that my University would be serious about its demonstration rules. When students break those rules, they should be punished, bar none. If Columbia can do it, so can we.

tumblr:  Giovanni Reder, Portrait of the cat Armellino, 1750. Oil on canvas. The first known painting of an individual cat. The italian poetess Alessandra Forteguerra commissioned the artwork of her beloved tom cat. Museo di Roma.

The Mister Tristan site says this:

Very few cats can boast that they have actually had their portraits painted, that is, that they have been depicted without any allegorical, moralizing, religious, esoteric, or simply decorative intent on the part of the artist….Armellino, wearing an elegant little collar, has literally posed on a luxurious cushion; a sonnet by the abbot Bertazzi has even been dedicated to him.

Now, I can’t find a translation of that sonnet anywhere. If any reader can, or can speak Italian, please provide me with a translation. I will credit the translator and put the sonnet in this post. You can enlarge the text by clicking on it.

Reader Brooke supplied the necessary sonnet:

The translation of the sonnet in the painting can be found on this page (you have to scroll down the page quite a ways):

Sonnet to a Cat

by Abbott Bertazzi

This Cat painted here on canvas,
tasted a loving kiss from a beautiful goddess,
after having done the portrait from life,
The cat keeps himself well guarded and most jealous.
In order to keep himself fully intact,
like an Ermine who lives in fear
and to avoid being caught
flees rapidly to stay in the wood or in a more hidden place.
So you as well, oh adventurous Cat,
preserve your mouth intact and your heart pure,
and only think of the one who kissed you,
and allow only me to love you,
you who shoot a kiss,
and take back my lovely kiss to cool the passion.

The cat’s name, Armellino, apparently means ‘ermine’ in old Italian.

Another site has an excerpt about this painting from H.V. Morton’s A Traveller in Rome (1957).

In a picture gallery upstairs [in the museum of Rome] I found a portrait of a black and white cat. This lordly and imposing creature prowled the marble halls of some seventeenth century palace and is here seen enthroned upon a tasselled cushion, wearing a broad collar to which bells are attached. Pinned to a curtain behind the cat is a little poem which says that a great and beautiful lady once kissed the cat and bade him keep his heart and mouth pure, and to remember her kiss. No one knows who the lady was.

Wouldn’t “the lady” be the cat’s owner? It’s rather confusing.

There are earlier named cats, of course, including Pangur Bán (“White Pangur”), the subject of a poem written by an Irish monk in a 9th-century manuscript. It’s a wonderful poem, comparable to “For I will consider my Cat Jeoffry,” by Christopher Smart, but, alas, there is no portrait of Pangur.

These are the two best cat poems ever.

The Japan Rail Club site gives us a look at a wonderful Japanese cat train (I think there are several). The article and photos are from Carlissa Loh, and go to the site to see tons of photos. If you’re an ailurophile, you’ll want to take this train.

Excerpts:

Would you take a 1.5-hour train in the Wakayama (和歌山) countryside just to see a cat? Many people would, and many have! In fact, it was thanks to a beloved cat, Tama, that one railway line was revitalised and saved from closure.

The railway line was Wakayama Electric Railway’s Kishigawa Line (貴志川線), and in January 2007, Tama (たま), a female calico cat, became the station master of Kishi Station (貴志駅).

Here’s Tama, the subject of a Wikipedia article in Japanese that autotranslates into English. It says, among other stuff, this:

Tama ( also known as Stationmaster Tama ; April 29 , 1999 ( Heisei 11) – June 22, 2015 (Heisei 27 )) was a cat and the honorary permanent stationmaster of Kishi Station on the Wakayama Electric Railway ‘s Kishigawa Line .

She was a female calico cat kept at the station’s convenience store and became an idol , like a maneki -neko (beckoning cat), before eventually becoming the station’s official mascot (a unique stationmaster, or cat stationmaster ) with the title of ” stationmaster ” and becoming world-famous . [ 3 ] She is now the station’s honorary permanent stationmaster.

On January 5, 2007, he was officially appointed as the stationmaster by the Wakayama Electric Railway, which caused quite a stir . [ 3 ] His main job was to “welcome customers,” and he is said to have not only attracted customers to Kishi Station, but also brought about the Heisei era cat boom, ” nekonomics ,” in Japan . [ 4 ] [ 5 ] [ 6 ] He was employed for life with no term limit , and his annual salary was one year’s worth of cat food .

Tama died in 2015, age 16.

But the Japan Rail Club says there’s a new stationmaster cat:

Her role of station master at Kishi Station was assumed by another beautiful calico cat, Nitama (ニタマ literarally “Tama two”), for whom curious travellers and excited fans alike travel all the way to the quiet station in Wakayama Prefecture.

Here is Nitama from CNN:

Notes (indented) and 3 photos from Carlissa Loh:

As a tribute to Tama, Wakayama Electric Railway started operating the Tama Densha train (たま電車), an adorable train with an exterior decorated 101 drawings of Tama donning a station master’s hat in various poses. Affectionately called “Tamaden”, the train’s front even has ears and whiskers, how cute is that? As a self-professed noritetsu, I love riding special trains, and knew I had to make room in my trip to take a ride on this train and pay a visit to Nitama.

Inside the train, there were even more darling drawings and decals of Tama adorning the windows and walls, and since it was the New Year’s period when I visited, there weren’t many other passengers, so I could take photos to my heart’s content.

The Tama Densha is made up of two carriages, and each one is furnished with wooden seats of varying designs of shades of orange, black, and white, and just oozed comfort and cosiness. The train was designed by Mitooka Eiji (水戸岡 鋭治), who has designed many memorable sightseeing trains such as the luxury cruise train Seven Stars in Kyushu, many of JR Kyushu’s D&S Trains, Kyoto Tango Railway’s sightseeing trains, and more.

I’d surely ride this train if I went to Japan (one of my dream destinations)!

And from Defector, Alex Sujong Laughlin interviews his cat Pong about the cat’s obnoxious behaviors. Click below to read:

Excerpts by Laughlin are indented:

Like every other member of my generation who has put off traditional markers of adulthood, like home ownership and having children, I am completely, utterly devoted to my cat, Pong. In the five years he’s lived with us, Pong has evolved from the scrawny street cat we adopted in the Union Square Petco to the ruler of our household. We often quote a decade-old Adam Serwer tweet about his own cats: Management doesn’t need a union.

We’ve invented a rich mythology for Pong’s inner life over the last five years. His hardscrabble early years taught him to flirt and charm for his meals on the streets of Harlem, where he developed his taste for French fries, noodles, and pizza. He ran with a tough crew that wasn’t afraid to get into scraps if he needed to assert dominance. He inherited his asthma and anxiety from his mother (me), and he spends his days working hard (sleeping on a chair in my office) for the money to pay our rent.

In any relationship, you fall into rhythms built around each other’s quirks and scar tissue. This is true even—or maybe especially—when the relationship is with an animal who cannot speak English. We’ve come to accept his most annoying behaviors; his loafing on our backs at 5 a.m. like a sleep paralysis demon is just a part of life with Pong, as are the lost hours of sleep and frequent yelling when he can’t find us in the house. \

I got a recommendation for a pet communicator, whose identity I’m keeping private at their request, and booked a 30-minute session with them. We met on Zoom, and when they started looking for his energy, they asked if he’s a male, six to eight years old, who’s very sure of himself. Pong was sleeping next to me in a little kitty croissant but the communicator couldn’t see him on screen. I told them they had the right guy.

What follows is an interview with Pong, through the communicator, which I’ve edited for clarity.

Just two Q&A’s via the pet communicator:

Can you tell me anything about your life before you came to live with us? 

There wasn’t a loving family, but there were two or three people who took care of me on the street. There was one man who I had a strong relationship with. There was a misunderstanding, the people tried to bring me into the house, and then took me away.

(This made me think of Alex, the doorman who apparently fed him when he was a stray, and who he was named for when he was brought to Union Square. Yes, we should’ve kept that name.)

. . .I appreciate that. OK, one last question. Sometimes you’ll crawl up onto my lap and be really sweet and snuggly, and then out of nowhere you’ll start attacking me, biting me and breaking skin. It really sucks when that happens! What’s going on? 

Sometimes I feel like I’m back on the street and it just happens. It feels right in the moment, but when you get upset I feel ashamed. I saw the tissues with the blood last week and I feel bad. It’s not your fault.

There’s a lot more Q&A at the site.

Millions of years of evolution have enabled some marine animals to grow complex protective shells composed of multiple layers that work together to dissipate physical stress. In a new study, engineers have found a way to mimic the behavior of this type of layered material, such as seashell nacre, by programming individual layers of synthetic material to work collaboratively under stress. The new material design is poised to enhance energy-absorbing systems such as wearable bandages and car bumpers with multistage responses that adapt to collision severity.

When navigating the modern world with its varied conveniences and modes of leisure, it seems that we humans are completely detached from the harsh environments that our species evolved out of thousands of years ago. Under stress, or in moments of crisis, however, the tools that our minds have evolved to deal with danger or imminent threat become quite apparent. During times like the recent global COVID-19 pandemic, when resources become unpredictably unavailable, we can turn to rather selfishly acquiring large quantities of particular products. From toilet paper rolls to baking flour, perceived essentials are coveted and cached away, hidden from other individuals, reserved for personal use in the future.

During such periods of uncertainty and upheaval, we aim also to construct meaning and a story line from the world rapidly changing around us—one by-product of which is the development of conspiracy theories. While such actions may be frowned upon in today’s society, and can be explained by hardwired behavioral reactions, they also point out the sophisticated cognitive tools that were likely critical to our evolutionary survival, indeed success, namely: recall of specific past events, future planning, the attribution of mental states to other individuals (theory of mind), a strong belief in some source of causation, and an underlying curiosity about the world we live in.

Thankfully, perhaps, we are not the only species with a tendency to cache goods when resources become scarce or when environments are risky—this is a trait we share with over 200 other vertebrates.1 Food-caching behavior is particularly impressive among birds such as the Clark’s nutcracker. This species lives in harsh seasonal environments and can cache tens of thousands of pine seeds within a season. Remarkably, they are able to remember and retrieve the seeds with great accuracy over nine months after storing them.2 The scrub jay on the other hand, caches a smaller number of more varied items, some of which perish relatively quickly (insects and olives, for example), and must therefore also keep track of the decay rates of different food items, and the passage of time, in order to successfully retrieve edible snacks.3 Are these remarkable behavioral feats potentially underpinned by sophisticated cognitive tools like our own, or can they be explained in terms of simpler, hard-wired behavioral predispositions?

Ethologists and comparative psychologists who study some of the cleverest organisms on the planet have grappled with such questions concerning the nature and origin of intelligence for decades, across a wide variety of different contexts and animal taxa. The comparative study of animal cognition has raised a number of critical questions over the years, including: Are other animals conscious?4 Can they “mentally travel in time” by storing specific memories and imagining the future?5 Are non-human animals able to attribute mental states to other individuals,6 and does curiosity motivate their interaction and exploration of these abstract phenomena?7 Ultimately, what is it about human cognition that sets us apart from other animals, and why? Trying to answer these types of questions is more important than ever. Not only does it give insight into the nature and origins of our own thinking and behavior, tackling these questions can also help us better understand, build, and predict artificial forms of intelligence, which are becoming increasingly embedded in the fabric of society and our daily lives.8

Though comparative cognition is a vast field, researchers are unified by a central challenge: unlocking the secrets of animal minds, which are like black boxes whose contents are neither directly visible nor accessible. Unlike work in human psychology that can partly rely on participants to report their own subjective experiences, research in animal cognition must employ creative behavioral tasks and interventionist approaches in order to test causal hypotheses about mechanisms that underlie behavior. This is the only way to tease apart hardwired responses or simpler forms of associative learning from more complex forms of cognition that could potentially explain behavior in question.9

Take, for example, the remarkable (and often frustrating) ability of ant colonies to identify and efficiently transport food from sparsely scattered patches in the environment to their nests. Research employing mazes has shown that Argentine ants are capable of solving fiendishly difficult transport optimization problems, flexibly finding the shortest path to food sources, even when known routes become blocked off.10 When watching individuals zealously journey out of the nest and back again, in close coordination with one another, it would be reasonable to assume that each ant had an understanding of the transport problem being solved, or that a central organizing force was shaping the behavior of the colony. Yet this feat is an example of self-organizing collective intelligence; a phenomenon that does not require a global controller, or even that the individuals be aware of the nature of the challenge that they are solving together. By adhering to simple, fixed rules of pheromone following and production, individual ants by means of only local interactions can produce complex collective behavior that does not rely upon any sophisticated cognition at all. This example highlights the need to employ carefully crafted experiments to elucidate correctly the true nature of behavioral processes.

Initially, comparative studies of complex cognition focused primarily on other primate species.11 Their close evolutionary relation to humans means they provide something of a window into the ancestral origins of our sophisticated cognition, and by comparison, the novel idiosyncrasies that characterize human intelligence (although they too have evolved both their bodies and their behavior in response to the selective pressures they have encountered since their split from us and our common ancestor). Nonetheless, it is anthropocentric to assume that complex cognition is exclusive to primates. Indeed, research on primate cognition has generated two influential hypotheses for the evolution of advanced intelligence that are applicable to a wide range of taxa. The Ecological Intelligence Hypothesis suggests that challenges associated with efficiently finding and processing food promote sophisticated cognition,12 while the Social Intelligence Hypothesis argues that activities involved in group living, including the need to cooperate with and potentially deceive others, drive the evolution of sophisticated cognition.13

Understanding the nature of intelligence is a tricky business but comparative psychology provides us with experimental tools that offer a window into the mind’s eye of other animals.

Over the last three decades increasing evidence has accumulated to show that a similar combination of selective pressures has driven the evolution of comparably complex cognition in other animal groups, notably the corvids.14 This group of birds, which includes crows, jays, ravens, and jackdaws, is capable of remarkable behavioral feats. These include the manufacture and use of tools for specific tasks,15, 16 and even the ability to “count out loud” by producing precise numbers of vocalizations in response to numerical values.17 The discovery of such behaviors points to complex underlying cognition, and given that primates and corvids diverged some 300 million years ago, it also suggests that advanced intelligence evolved independently at least twice within animals as the result of convergent evolutionary pressures.

In order to closely elucidate the nature of intelligence in animals, it is instructive to first identify natural behavior that may reflect complex cognitive processes, especially ones that can also be studied in controlled laboratory conditions. The food caching behavior of birds has proven to be a powerful model through which to investigate the nature of animal intelligence across a range of domains, including recall of past events, future planning, and the ability to attribute mental states to other individuals (“Machiavellian intelligence”). In particular, laboratory studies on scrub jays have leveraged that species’ propensity to cache a variety of perishable foods, but not eat items that have degraded. How do individual birds efficiently recover the hundreds of spatially distinct caches they make daily, given that different food items decay at different rates?

In a notable study published in Nature,18 researchers hypothesized that jays use a flexible form of memory that previously had been thought exclusive to humans—episodic memory. Episodic memory allows us to recall specific events that have occurred in our mind’s eye, and we experience these memories as our own, with a sense that they represent events that have occurred in the past. In the absence of a method to ascertain whether jays subjectively experience memories as we do, the researchers proposed behavioral criteria that would indicate “episodic-like” memory: an ability to retrieve information about “where” a unique event or “episode” took place, “what” occurred during the event, and “when” it happened. To test this, they conducted a series of experiments in which jays were presented with perishable worms that could be cached in trays at one site and non-perishable nuts that could be cached at another. The results of the experiments showed that when given the option to recover caches after a short time, the birds preferred to search for the more desirable, tasty worms, but switched to searching for the less attractive nuts after longer delays, when the worms had decayed. These experiments demonstrated for the first time that a non-human animal can recall the “what-where-when” of specific events in the past using abilities akin to episodic memory in humans.

While birds might rely on recall of specific events to successfully retrieve cached items, the initial act of caching itself is prospective, functioning to provide resources for the future when they might otherwise be scarce. This raises the possibility that non-human animals are capable of future planning, mentally traveling forwards in time to anticipate future needs that differ from present ones. However, caching may also simply be a hardwired behavioral urge, rather than a flexible response that is reliant on learning. To explore this, researchers tested scrub jays using a “planning for breakfast” paradigm.19 Over a period of six days the jays were exposed daily to either a “hungry room” where breakfast was never provided, or a “breakfast room” where food was available in the morning. Otherwise, the jays were provided with powdered (uncacheable) food in a middle room that linked the other two. Then, the birds were offered nuts in the middle room, and the opportunity to cache them in either the hungry or breakfast room. The results showed that the birds spontaneously strongly preferred to cache the nuts in the hungry room, indicating for the first time that a non-human animal can plan for the future, guiding its behavior based on anticipated future needs independent of their present motivational state.

The examples above demonstrate the ability of birds to “mentally travel in time” and form representations of their own past and future. To recover their caches successfully, however, each individual bird must also pay attention to the other birds who might attempt to steal their caches. To lessen the risk of that happening, individual birds employ a range of strategies to protect their stored food, including caching food behind barriers, out of the sight of other birds, and producing decoy caches that do not contain any edible items. To explore the cognitive processes involved in cache protection behavior researchers allowed scrub jays to cache food when alone, or while being watched by another bird. The caching birds were then provided the opportunity to recover their caches while in private, giving them a chance to re-cache the hidden food items that might be vulnerable to pilfering. Interestingly, not all birds re-cached the items most at risk of being stolen (those cached in front of the conspecific). Only those scrub jays who were experienced pilferers themselves decided to re-cache items that had been watched by another individual.20 The implication is that birds who have been thieves in the past project their experience of stealing onto others, thereby anticipating future stealing of their own caches. In other words, it takes a thief to know one! This experiment therefore raises the possibility that the jays simulate the perspectives of other individuals, suggesting that like humans, they may be able to attribute mental states to others, and therefore have a knowledge of other minds as well as other times.

The approach employed in these studies highlights the utility of exploring behavioral criteria indicative of complex cognitive processes by using a carefully controlled experimental procedure. One advantage of this approach is that it is widely applicable, since it relies on externally observable behavior, rather than obscure internal states, and can therefore be used to investigate a diverse range of intelligences. Recently, comparative psychologists have started to apply these techniques to systematically investigate the intelligence of soft-bodied cephalopods—the invertebrate group comprised of octopus, cuttlefish, and squid.21 These remarkable animals have captured the imagination of naturalists for hundreds of years and reports suggest they are capable of highly flexible and sophisticated behaviors. For example, veined octopuses transport coconut shells in which they hide themselves when faced with a threatening predator, raising the possibility that they may be able to plan for the future. Further, the male giant Australian cuttlefish avoids fights with other males by deceptively changing their appearance to resemble that of females—perhaps they are capable of attributing mental states to other members of their species.

Recently, laboratory experiments with the common cuttlefish have shown that like some birds, apes, and rodents, they are able to recollect “what-where-when” information about past events through episodic-like memory.22 Unlike other species however, episodic memory in cuttlefish does not decline with age, offering exciting opportunities to study resistance to age-related decline in cognition.23 As with food caching among corvids, behavioral experiments with cuttlefish have also revealed prospective, future-oriented behavior: after learning temporal patterns of food availability, cuttlefish learn to forgo immediately available prey items in order to consume more preferred food that only becomes available later.24, 25 Presently, however, it is not clear whether this reflects genuine future planning, which requires individuals to act independently of current needs—and so presents an exciting avenue for future research.

Given the broad applicability of the experimental approach developed in comparative psychology, it is worth considering the utility of experimental paradigms to investigate the behavior of non-organic forms of intelligence. Artificial Neural Networks (ANNs) are becoming increasingly embedded in the way that we work, solve problems, and learn, perhaps best exemplified by the advent of Large Language Models (LLMs), such as ChatGPT, now ubiquitous by their use in content creation and even serving as a source of knowledge.26 It is more important than ever that we develop an understanding of the behavior of these forms of intelligence. Fortunately, decades of research aimed at understanding the minds of animals has provided us with the conceptual tools needed to elucidate the processes underlying artificial behavior, and the means to build a form of artificial intelligence that is more flexible and less biased. Though reports of ANNs besting humans in traditionally complex, strategic games such as poker abound,27 some have argued that these wins are often restricted to very specific domains, and that ANNs are far from displaying the general intelligence of animals, let alone humans.28

Interdisciplinary efforts, however, are helping to close this gap. Inspired by research in cognitive psychology, computer scientists have incorporated an analogue of episodic memory into the architecture of ANNs. Endowed with the ability to compare present environmental variables with those encountered during specific points in the past, ANNs are able to behave much more flexibly.29 Recently, influenced by classic tasks in comparative psychology, psychologists and computer scientists have collaborated to produce a competition testing the relative cognitive abilities of ANNs.30 Dubbed the “Animal-AI Olympics,”31 this competition should help to promote the development of artificial forms of intelligence capable of mirroring the general intelligence displayed by animals, and perhaps one day, humans.

Understanding the nature of intelligence is a tricky business, but comparative psychology provides us with experimental tools that offer a window into the mind’s eye of other animals. In the future, these approaches may prove invaluable in providing insights into the behavior of artificial forms of intelligence, and one day, perhaps, into the behavior of organic life that looks very different from that on Earth.
