"For the first time, scientists have used artificial intelligence to create new kinds of viruses... raising the disturbing possibility that the technology could someday be used to invent dangerous pathogens."

I'm reading "This A.I. Just Created Viruses Not Found in Nature/Scientists trained artificial intelligence on libraries of DNA and then asked the model to create recipes for viral genomes. Sixteen of them were viable, yielding new viruses" (NYT gift link).
Researchers long ago learned how to manufacture viral genomes; they are used to investigate antiviral drugs and vaccines, as well as to learn how viruses work. But [in] the new study... [s]cientists... taught A.I. to recognize patterns of DNA structure in nature, and then to use that data to write recipes for entirely new viruses. The researchers followed those recipes to create DNA molecules, which they inserted into bacteria. The modified bacteria then produced viruses never seen in nature. The viruses were able to infect other bacteria, demonstrating that they were viable.

I hadn't used my "deeply" tag since last May.

It's a deeply bloggy tag, so it makes me want to do a post collecting recent iterations of "deeply." The first time I used it — in "Deeply... it's such a poser word" — I had a 12-point list. That was back in 2014. Let's see what "deeply" has been doing lately.

1. "The Once-Shameless President Is Deeply Embarrassed/As Donald Trump faces one humiliation after another, he is attacking those he blames" by Jonathan Lemire in The Atlantic, published today. Gift link. "But how Trump will respond next to this ongoing embarrassment remains unknown. He’s made the war deeply personal. Will he now bail on the stalled war entirely, leaving Iran more empowered in the region? Will he follow through on his threats to dramatically escalate the conflict, perhaps even to strike civilian infrastructure and energy sites? Or will he channel his rage against Americans who point out his mistakes?"

2. "UN rips ‘deeply troubling’ Iran for executing at least 56 people since start of war: ‘Has no place in our world'" — published today in The New York Post. "Several people were executed in the last two weeks alone, including a 19-year-old charged with 'enmity against god' for allegedly partaking in January’s protests. Two others arrested during the protests were also executed. And in July, two people were executed out of a group of 12 convicted of 'corruption on Earth' and 'enmity against God' over connections to four police killed in January."

3. "Ken Jennings Says He Cares 'More Deeply' About Trans Rights Than Any Other Issue" (Them, August 3, 2026). "Ken Jennings... recently got into a relatively minor back-and-forth on Bluesky with people who claimed his subscriptions to the New York Times were supporting an anti-transgender media organization.... Would I subscribe to the New York Times? No. Would I unfriend someone who did? Not necessarily.... Do I do the crossword puzzle? Yes, because nothing else quiets the anxiety I feel about living in our current reality quite like trying to find a five-letter word for boredom. Ah, 'ennui,' my old friend."

4. "The Woody Guthrie story you’ve probably never heard is deeply Jewish/A documentary recasts the folk singer’s legacy through the influence of his mother-in-law, Yiddish poet Aliza Greenblatt" (Jewish Telegraphic Agency, August 3, 2026). "The film ['Dust Bowls and Jewish Souls: Another Side of Woody Guthrie'] makes the case that Guthrie’s extended Jewish family was not incidental but integral in his artistic and personal evolution. It is a story that stretches from Oklahoma to Coney Island to the Yiddish literary world, and from the folk revival’s Jewish impresarios to one remarkable immigrant woman whose influence has largely gone unrecognized."

5. "Neil Shubin on Trusted Science in a ‘Deeply Partisan Age’/An eminent fossil hunter takes the reins at the National Academy of Sciences in a turbulent moment for American researchers" (NYT, June 2026). "As an institution, we are — by charter and design and history — nonpartisan. But we are in a deeply partisan age. Just by doing our work, we will be viewed in a partisan light no matter what. So our job is to double down on the science. We need to be a trusted source of data."

6. "'I Deeply Believe Dogs Have Superpowers and Secrets’/Prompted by a fierce attachment to his own pet, Paul Yoon wrote a harrowing yet hopeful novel, set during wartime, told from a canine perspective" (NYT, August 2, 2026). "Like his finest literary forebears who have written from a dog’s perspective — Virginia Woolf ('Flush'), John Berger ('King: A Street Story'), Jack London ('Call of the Wild') — Yoon pulls it off without being treacly or condescending.... It helps that Etna can understand everything that’s said by people around him. This was partly a practical choice, as Yoon explains: 'I wanted to create a bridge for the reader to experience this world and this journey.' But, he added, 'I deeply believe dogs have superpowers and secrets.'"

7. "The Deeply Human, Complexly Queer Animated Animals of 'Bouchra'" (autostraddle, August 3, 2026). "In Meriem Bennani and Orian Barki’s bold film Bouchra, an NYC‑based lesbian filmmaker... tries to process her relationship with her Moroccan mother through a semi‑autobiographical meta‑fictional drama stemming from a coming‑out letter she sent nine years prior.... It’s told via anthropomorphic animals in a hyperrealized backdrop.... [E]ntirely animated in Blender, Bouchra’s experimental animal‑filled approach takes some getting used to."

"Up to 50 million tonnes of sugar may have rained down from space on to Earth about four billion years ago, potentially delivering the building blocks of life..."

"... a study has found. Scientists have discovered sugar molecules in clouds of interstellar gas, suggesting a key ingredient for DNA and RNA could have come to our planet from deep space...."

I'm reading "Sugar raining down from space may have helped create life on Earth/Cluster of sweet molecules in Milky Way gas cloud offers clue to possible origins of DNA, astronomers claim" (London Times).

"During the Enlightenment, close attention emerged as a virtue essential to knowledge and disciplined investigation, as demonstrated in 1740, when the naturalist Charles Bonnet..."

"... conducted a vigil of 21 days, daybreak to nearly midnight, to study the life cycle of a single aphid. At the dawn of the 20th century, the American philosopher William James insisted that voluntary human attention was the linchpin of free will. By that time, some laboratory researchers had begun to turn their attention to attention as a subject of explicit scientific inquiry. One of the first to undertake such investigations was James McKeen Cattell, a German-trained American at the University of Pennsylvania. Dr. Cattell, the first professor of psychology in the United States, used a fast-snap shutter to flash a few letters for a tiny fraction of a second. The test subjects then repeated back to him as many letters as they could remember. Observing a range of results, Dr. Cattell concluded that they reflected a significant feature of cognitive ability: what he called the 'span' of attention. Subsequent researchers used the attention span metric to identify children’s mental 'deficiency.'"

Write D. Graham Burnett, Alyssa Loh, and Peter Schmidt, in "The Century-Old Lie at the Heart of the Attention Economy" (NYT).

Burnett, Loh, and Schmidt have a book, "Attensity!" (commission earned). The word "attensity" appears in the column like this:
"Defeating the forces that frack human beings in order to extract the financial value of their attention is going to require... attention activism... a new politics of 'attensity.'"

"Rejection of genuine expertise is both a precondition and a function of autocracy. Joseph Stalin’s regime outlawed genetics as 'pseudoscience'..."

"... while he himself was declared an expert in all fields, from linguistics to biology. Contempt for expertise is not the only autocratic force at work in the case of S.B.1 [the Tennessee law banning puberty blockers and hormones for transgender children]....  I expect the court to uphold the Tennessee law.... [I]t won’t stop with trans care. Governments at different levels will be emboldened to meddle in what should be private, family decisions. In and out of government, people who know what they are talking about will be supplanted by people who perform their loyalty most loudly. Quackery will continue its ascent; expert consensus, not only in medicine but in all the disciplines that enable us to know and navigate the world, will be marginalized...."

Writes M. Gessen, in "The Supreme Court Just Showed Us What Contempt for Expertise Looks Like" (NYT).

Why did Gessen write "genuine expertise" if not to admit that experts can go wrong? Obviously, autocrats have their "experts" too, and respecting them has done great harm. I think first of Josef Mengele, who earned a cum laude doctorate in medicine from the University of Frankfurt for a thesis dealing with genetics and who conducted genetic research at Auschwitz. That doesn't make genetics a "pseudoscience," but it does show that we'd be fools to think there's a binary choice between deference to experts and marginalizing them.

Here's the Wikipedia article about the Soviets' banning of genetics. I can see that those who did the banning regarded themselves as experts:

Grok tries to help me analyze the "ethicality" of attaching a camera to your baby's head and deviously distracts me with the question of gluing hair onto the head of one's 3-year-old.

Here's my screen shot (and I'll tell you in a minute why I was asking this question):

 
I don't know why Jim Gaffigan had his question, but I had my question because I was reading the NYT article "From Baby Talk to Baby A.I./Could a better understanding of how infants acquire language help us build smarter A.I. models?" 

We read about a 20-month-old girl who wears "a soft pink hat" with a "lightweight GoPro-type camera... attached to the front." This particular child is only wearing the camera once a week for one month, but scientists are asking...

"The sun would appear green if your eye could handle looking at it."

"Basically, when you look at the sun, it has enough of all the different colors in it and it’s so bright that everybody’s eyes are firing like crazy and saying, 'It’s too bright for me to tell you what color it is.' That’s why the sun looks white to us... 'Essentially, it’s a green star that looks white because it’s too bright, and it can also appear yellow, orange or red because of how our atmosphere works.... 'The sun is at its midlife, and it still has quite a lot of years before it changes colors.... It still hasn’t dimmed out one bit.... When astronomers say color, they really mean temperature.... But to anyone in the public, color just means the color you see and how you make sense of the world."

Said W. Dean Pesnell, project scientist of NASA’s Solar Dynamics Observatory, quoted in "Is the sun white or yellow? It’s a hot debate, and everyone’s wrong. Plot twist: It’s green" (WaPo).

According to the article, some people on social media are discussing whether the sun used to be yellow and now it's gone white.

Peanut butter is a liquid.

I'm reading "Don’t Try to Board a Plane with Peanut Butter/Sticky and solid as it may seem, the spread is technically a liquid" (The Atlantic).

The author, Ted Heindel, a mechanical engineer who studies fluid flows, explains why it made sense for the TSA to subject a jar of Jif to the 3.4-ounce rule about "liquids." It may seem wrong, but how much do you really know about what is a liquid?

"While reading 'Spring Rain: A Life Lived in Gardens,' by Marc Hamer, I often found myself wondering how old its author was..."

"... in part because the arc of the book follows Hamer getting too old to work as a gardener anymore. However, I hesitated to research his age. In Chapter 10, titled 'Gardener,' Hamer mentions the discovery, in 2006, of the world’s oldest living creature, a clam. The clam, named Ming, was five hundred and seven years old. It had been found off the coast of Iceland, and died when the scientists who discovered it tried to ascertain its age."

"In reality, feminist science offers a powerful set of tools for examining the history, context, and power structures in which scientific questions are asked."

"By bringing marginalized perspectives to the table, it can generate new questions and methodologies that help scientists identify and correct for hidden bias. Think of it as a stake strapped to a growing tree: it provides scaffolding to help the tree get back on track when it starts to lean too far to one side.... In 2012, [evolutionary biologist Patricia] Gowaty performed a series of careful replication experiments with fruit flies that challenged the longstanding 'Bateman’s Principle' of sexual selection. Her findings helped show that this principle, which states that males tend to be more promiscuous than females due to the asymmetry between sperm and eggs, was more of a hypothesis — and a flawed one at that."

"And though sex differences in sports show advantages for men, researchers today still don’t know how much of this to attribute to biological difference..."

"... versus the lack of support provided to women athletes to reach their highest potential. 'Science is increasingly showing how sex is dynamic; it has multiple aspects and also shifts; for example, social experiences can actually change levels of sex-related hormones like testosterone in our bodies in a second-to-second and month-to-month way!' Sari van Anders, the research chair in social neuroendocrinology at Queen’s University, in Ontario, told me by email."


I was surprised that the research chair in social neuroendocrinology used an exclamation point! But what is social neuroendocrinology? I don't know! Is it more like sociology?

Here's something from a clearly identified sociologist:

"At least half of humanity combs their hair every day, and yet almost no one pauses to think deeply about it."

Said Harvard scientist L. Mahadevan, who studies mathematics, physics, and organismic and evolutionary biology, quoted in "Scientists Unravel Mysteries Of Brushing Tangled Hair --- Researchers at Harvard, MIT use math, lab work to develop pain-free techniques" (Wall Street Journal).

The knotty hair puzzle reached Prof. Mahadevan's lab three years ago, as he was thinking about how birds build nests. His research led to the question of tangles, which also occur at the microscopic level in DNA helixes and in magnetic flux lines crisscrossing the cosmos....

"The unlinking of the homochiral helixes during this process can be quantified in terms of the Calugareanu-Fuller-White (CFW) theorem which states that Lk=Tw+Wr, where Link (Lk) quantifies the oriented crossing number of the filaments averaged over all projection directions" and so on....

As you know, if you've combed tangled hair with any competence at all, it doesn't work to start at the top and comb down. You work up from the bottom. Mahadevan, despite being a genius, couldn't comb his 5-year-old daughter's hair. But it percolated in his head for 20 years, and he ultimately did some sophisticated research (as you can see) that explains why you're going to want to start from the bottom and work your way up. Most of us observe and guess and do trial and error, but there's a place in this world for the genius, even if he can't comb a little girl's hair intuitively. We're told he has also studied "why Cheerios clump in a bowl of milk."

"I’m terrified... Terrified, and I do not scare easily."

I'm reading the top-rated comment at the NYT article, "Hundreds of Epidemiologists Expected Mask-Wearing in Public for at Least a Year/The C.D.C. said Thursday that vaccinated Americans no longer needed masks in most places. Other disease experts recently had a different message: that masks were necessary in public." 

The NYT seems to be stimulating fear in reaction to the CDC announcement. The survey the headline refers to was taken before the CDC took its new position, so these epidemiologists — 723 of them — were, I suspect, passing along the party line. Did they do their own studies? Even if they did, do they study the costs of the restrictions or simply, endlessly default toward caution?

Here's the full comment: 

This is a horrible, horrifying decision. There’s no way to prove who’s vaccinated and who isn’t. People are going to lie about their status. We were out shopping today and my husband saw a woman wearing a mask that said “This mask is as useless as my Governor.” Does she seem trustworthy? Does she maybe seem like someone who’d doff her mask at the first chance, whether she’d been vaccinated or not, because she’s an imbecile and has no regard for the lives of others?

What difference does it make? If you know you're vaccinated and you believe vaccines work, you're fine without your mask, and only the unvaccinated are at risk. Why are you obsessing about the mind of a stranger?

Helleborus.

I can never remember the name of this flower.

It's Helleborus. It looks a lot like another flower I have trouble remembering, Ranunculus. Ridiculous! I end up referring to it as "Homunculus," which I know is wrong, but amuses me to say. In truth, a "homunculus" is...

"The doctors-facts-science mantras have become familiar over the past year. The experts tell us, expertly, what we need to know, and we do it."

"At least until all this science starts to fog up our mental windshields and we, the people, start to wear out. Our irritability mounts; our attention wanes; the guide-rope in our mouth starts to chafe. It is then that the bawdy obstreperousness and its odd twin, the glory hallelujah, of democracy come into view — a single unit; maddening, infuriating, nevertheless fused. And Greg Abbott or someone else steps up to lead the beast forward, by instinct if not by Hoyle... The love of democratic citizens for experts shouldn’t be overestimated. The nature of democracy is preference for or deference to popular wisdom, however unwise that wisdom may prove in action. It’s been a long time since this pandemic started. People are tired. People want to see, and relate to, each other. That’s human nature. The human nature-affirmers like Greg Abbott, with a little luck and sense of timing, are likely to come out way ahead of their castigators and vilifiers, Robert Francis (Beto) O’Rourke conspicuously included."

Writes William Murchison in "Glory Hallelujah for Texas!/Gov. Greg Abbott takes a calculated gamble on we, the people against the experts" (The Spectator).

The Spectator is British, but Murchison is American. He even went to the University of Texas. I had to look that up because the use of "glory hallelujah" hit my ear as a foreigner's mistake. To me, the phrase — which you see in the title and the text ("its odd twin, the glory hallelujah, of democracy") — is entirely evocative of "The Battle Hymn of the Republic," and Texas was in the Confederacy. 

Puzzling, I ran across this 2018 NPR article, "How 'The Battle Hymn of the Republic' became an anthem for every cause"

There's an episode of The Johnny Cash Show from 1969 where the man himself makes a little speech with a pretty big error. "Here's a song that was reportedly sung by both sides in the Civil War," Cash says, guitar in hand, to kick off a performance of "The Battle Hymn of the Republic.... which proves to me that a song can belong to all of us."

 

Cash was wrong, but in the years after the Civil War, the song came to be sung in church, at football games, and at labor union events. And on all sorts of political occasions:

Why is ice hockey the one youth sport producing outbreaks of coronavirus?

"One critical way hockey differs from other contact team sports is how players do line changes — substitutions of groups of players — and are expected to sprint for nearly the whole time they are on the ice. Experts say it probably leads to heavier breathing, resulting in more particles being exhaled and inhaled. Jose-Luis Jimenez, an air engineer at the University of Colorado, speculated that the spaces occupied by rinks keep the virus suspended, perhaps six to nine feet, just above the ice. Similar outbreaks have been documented in other chilly venues — meat processing factories and at a curling match earlier in the pandemic. 'I suspect the air is stratified,' he said. 'Much like in a cold winter night, you have these inversions where the cold air with the virus which is heavier stays closer to the ground. That gives players many more chances to breathe it in.'...... Surrounded by plexiglass not only to prevent errant pucks but also to keep the airflow stable so the ice can remain cold, there’s little ventilation and humidity by design in ice rinks.... In higher humidity, the virus attaches to bigger droplets that drop faster to the ground, decreasing the chance that someone will inhale them. The drier the air, the faster droplets will evaporate into smaller-size particles that stay in the air, increasing the concentration..."
