Latvian manhole cover


No useful comments in the Facebook discussion thread.  I could't find evidence that this image is from Hieronymus Bosch.  I've joined the group to see what else might be posted there.  There is also a subreddit of manholeporn where years ago I found this very "metal" manhole cover.

This is what is keeping crude oil and gas/diesel prices from skyrocketing


When Trump and Netanyahu started this war, much of the attention in the business world was focused on the price of crude oil (Brent, WTI) and the derivative products (gasoline, diesel, fertilizer, plastics).  When the Strait was closed and then reopened via the MOU, prices fluctuated accordingly, but what has been of most interest to me is that the market prices of those materials have not continued to rise as much as might be expected.

Everyone who tracks the news knows that the U.S. and other countries are tapping their "strategic petroleum reserves" stored underground (some small countries don't have such and are suffering disproportionately).  

The second group of factors that mitigated price rises was increased use of alternative energy, restrictions on energy usage, increased production in non-Gulf nations etc.

But from near the beginning, I heard analysts on Bloomberg say that China was modifying its policy on oil.  China apparently has immense reserves of stored oil, but were still net oil importers (see chart above for 2016-2026).  After the war started, they have markedly decreased their importation of oil, apparently using some of their reserves and altering domestic policies toward conservation.

Why?  In part, it's basic economic good sense when the Brent price goes from 50 to 90 to cut purchases.  But this is a super-smart country with well-thought-out international policies.  They also have a sort of alliance with Iran, which I believe was one of their sources for imported oil in recent years.   By cutting their daily imports from 12 million to 7 million they buffer the world's loss of I think 5 million a day that was passing Hormuz.

Is it in their best interest (remembering that they think years/decades in advance, not election cycles) to keep the oil price rise modest so as not to harm the economies of the world they export to?  Or do they want to keep the price down because a huge price rise might cause the U.S. to stop the war and they would rather the war go on longer so the U.S. depletes its own reserves and the continuation of the war leads to more and more destruction of the U.S. military capabilities?  I suspect the latter, because I think there is way more erosion of U.S. capabilites in the Gulf than Washington has (or will) admit.

Also note that Iran wants to charge fees for transit of Hormuz and that those fees would be paid in Chinese yuan, not U.S. dollars.  (a relevant WSJ article is behind a paywall)  This was is weakening the U.S. military capabilities, depleting strategic petroleum reserves, ruining the U.S. diplomatic status around the world, and causing unhappiness and political dissent within the U.S.  China has a lot of control over how this will unfold.  Stay tuned.

Update on the war


As reported by the Institute for the Study of War yesterday (July 28).  I was so glad to see an informed discussion of the various competing groups within the Iranian regime.

Note this was written just before the latest acceleration of hostilities.

For those unfamiliar with the source: "The Institute for the Study of War advances an informed understanding of military affairs through reliable research, trusted analysis, and innovative education. We are committed to improving the nation’s ability to execute military operations and respond to emerging threats in order to achieve US strategic objectives.

"Colossal" - recommended (with a reservation)


This movie has been categorized as "black comedy sci-fi", which seems reasonably appropriate.  It's not a new movie (2017) but was new to me last night, and this morning I decided to share some thoughts.

Most science fiction requires some "suspension of disbelief" in order for the viewer or reader to "enter" and enjoy the story.  Conventional storylines may require your rational hemisphere to accept time travel, faster-than-light vehicles, aliens who speak English, or hybrid humanoid synths; once you do that, you're "good to go."

For this movie the required suspension of disbelief is evident in the trailer embedded above.   Anne Hathaway is excellent in her lead role as a young woman who is simultaneously a Seoul-crushing monster.

My one reservation regarding enjoying the movie is in regard to Jason Sudeikis' character.  "Colossal" was released in 2016, four years before Sudeikis emerged as "Ted Lasso" in the recurring TV series.   If you start the movie (as I did) with a mindset that Ted Lasso is flirting with Anne Hathaway in a rom-com, then you will need to make major readjustments, because his character has a major (and dominating) dark side evident in the closing scenes.  There is also implied commentary on the potentially detrimental effects of alcohol consumption.

But if you like Anne Hathaway, you might give this one a try.  The Rotten Tomatoes score is 82%, with professional reviewers bouncing all over the place from "unmissable" to "incomprehensible."  Your thoughts/memories are welcome in the Comments.

Adjustable light bulbs


I was today years old when I discovered that there are adjustable light bulbs.   Had to replace some of the bulbs in several ceiling cans.  Got to Target without checking what type of bulbs (warm vs. cool) were in the other cans, and discovered that now you can buy multipurpose bulbs and then adjust them at home.


The older I get the more I find myself echoing my 97-year old late mother's phrase of awe and admiration:  "This modern world..."

Dandelion bonsai


It was not until my adult retirement years that I began to understand that dandelions are perennials.  I have harvested some really deep-rooted ones in the loose soil of a backyard tomato patch (I even pondered entering one such plant into a state fair ag competition).  And it was not until yesterday that I discovered that they can be used for bonsai-type art.

I found enough other material online to be reassured that the image above isn't pure AI.  Whether it is true "bonsai" can be argued; you can read about such viewpoints at Reddit and via the Google AI.

Three-year-old plays the piano

Hormuz update


Found on Facebook.  The company's website does not mention this event, but I did find this report from two days ago, which cites the Financial Times and Reuters (to which I don't subscribe).
Greek maritime security company Marisks said the Acheloos and Kavomaleas were struck at about the same time, as they transited the US-facilitated southern Hormuz corridor.

Iran’s Islamic Revolutionary Guard Corps said two ​tankers “exploded” and were immobilised after ​attempting what it called unsafe southern route through the strait, Reuters reported.

Those who care about the ocean and the environment will be pleased to read that the supertanker was empty: "The tanker had been scheduled to load more than 500,000 barrels of oil in the Middle East Gulf."

I found this in Jerusalem Post

MK Moshe Saada (Likud) said on Thursday that "an attack against Iran is approaching," during an interview with Channel 14 News.

Saada's comments were made against the backdrop of growing tensions between the United States and Iran, and assessments that an escalation could occur in the coming days.

During the interview, while discussing Iran and the possibility of further escalation, Saada said, “We all know that we are approaching an attack on Iran, perhaps even as early as this weekend; those are the assessments.”

The channel quickly presented the remarks under the headline, “MK Moshe Saada’s slip of the tongue.” However, this was not the first time Saada had publicly addressed the possibility of an imminent attack.

Over the past week, he suggested on several occasions that, in his assessment, military action could take place within days. His remarks therefore appeared to be deliberate rather than an accidental disclosure.

At the same time, Channel 13 News reporter Michael Shemesh reported that Prime Minister Benjamin Netanyahu’s office was furious over Saada’s comments on Channel 14. According to the report, the Prime Minister’s Office viewed the remarks seriously.
That was posted at 2223 today Jerusalem time, which was less than an hour ago.

I have seen similar suggestions on Al Jazeera and on unreliable Facebook pages.  To see it being openly discussed in Israeli media is another matter altogether, and very worrying, because Trump has been saying that he will decide soon whether to escalate further because of the involvement of the Houthis.  IMO putting "boots on the ground" would be catastrophic.

"The Hermit of Treig"


Yesterday evening I was looking for some distraction from doomscrolling the internet.  While wandering around I found the above movie on Amazon Prime (free with ads).  The sparse Wikipedia entry described it as a Scottish documentary portrait of an elderly man who has lived for 40 years "off the grid" in a log cabin in the Highlands.  The film has received multiple audience awards at festivals and was the Best Single Documentary at the 2022 British Academy Scotland Awards.

Worth a try I thought.  In a bad mood because of the obligatory introductory ads on Prime, I at first became frustrated with the film's slow progression and started to click the fast-forward a few times.  But then the story started to fill out with some historical context about the earlier life of this remarkable man wandering the Yukon.  Within half an hour I was totally absorbed, and by the end I deemed it to be worth recommending to others.

The film will not be for everyone.  If someone is Gen Z with a vibrant social and digital life, the appeal of this man's story will be severely muted or absent.  For me there was a very strong resonance since I am older than he is and have always treasured time spent in the woods (but I cringed every time I saw him carrying his firewood over irregular rocky ground without even a proper walking stick).  I am pleased to offer a "spoiler" by reporting that he is very much alive and well at the end of the film (and today).

My local library system did not have a DVD of this movie, but I did find that he has written a book (The way of the hermit : my incredible 40 years living in the wilderness, by Ken Smith).

Was the sign designed like this on purpose ?

A challenge


I've been enjoying the cryptic puzzles in Harper's for decades.  After you figure out the cleverly-constructed clues, entering the answer often involves another step, as in this case.

I've not embedded the entire puzzle, because blogging ethics standards on TYWKIWDBI are to drive readers to the source, not steal from the source.  If any wordsmiths out there would like to tackle this very challenging grid, the full puzzle is available in the August issue of Harper's Magazine, available online or in your local library.

Trinket trade boxes

Bloomington nurse and mom Roze Mulen poses with her trinket trade box, where people can swap figurines and toys. 
(Roze Mulen/Provided)
The trinket trade is taking root thanks in part to America’s trending obsession with blind boxes. The Asian retail craze drives shoppers to gamble on purchases of collectible toys and figurines. But buyers don’t know which item is in the box until they open it.

Roze Mulen, a nurse and mom in Bloomington, said her office is packed full of trinkets, including duplicates she’s unknowingly bought in blind boxes. After scrolling on TikTok and seeing people across the country start trinket swaps, she decided to bring the idea to the Twin Cities suburbs...

Trinket trade boxes have lately been popping up across the Twin Cities and in the suburbs especially, as parents and artists like Ross aim to add more whimsy to their residential streets and subdivisions sometimes known for their sameness.

“I wanted to build an interactive community-wide art piece where everyone gets to feel that childhood magic,” Ross said. “It’s not just about trading items. It’s about trading moments of joy.”
Buying boxes of unknown products on the internet seems to me a chancy proposition, but moments of joy are in short supply these days, so if this variant of the Little Free Library does bring joy to others, good for them.  More info at the Star Tribune.

Add "crack spread" to your economic vocabulary


I found the "recent work" that Jonathan Ferro is referring to in his introduction to Jeffrey Currie.  Couldn't find a text version to summarize, but here's a longwatch video interview that has extensive details about the matters being discussed:


The essence of the interview is a question about why the price of oil (as reflected by Brent crude and WTI (West Texas Intermediate) has remained (relatively) stable despite the ongoing conflict in the Gulf.  Those prices went way up when the "hot war" started, then moderated back down when the "memorandum of understanding" was executed, and now they are heading back up in a gradual fashion.

I have not previously been aware of Jeffrey Currie, but his reply (starting at the 1:15 mark of the second video) is exactly what I've been thinking - so I assume he is a brilliant genius.  His Wikipedia page indicates that he is a highly-respected economist at the University of Chicago.  Listen to as much of that interview as you have time for.  I heard the same arguments presented live to Jonathan Ferro this morning on Bloomber's Surveillance program in the pre-market and I was blown away by the insights.

For the TLDR and TLDW crowd, I'll add some more nuggets.  First the definition of "crack spread":
Crack spread is a term used on the oil industry and futures trading for the differential between the price of crude oil and petroleum products extracted from it. The spread approximates the profit margin that an oil refinery can expect to make by "cracking" the long-chain hydrocarbons of crude oil into useful shorter-chain petroleum products.
And before I move on, one note.  Any juvenile salacious comments about "crack spread" will be instantly vaporized on review.  The comment section here is for serious discussions of the world economy.

Here is an inadequate quick summary for those without the patience to watch the videos.  The news media and the general public focus on the "price of oil," but nobody actually uses crude oil.  People use gasoline, farmers and truckers and businesses use diesel, everyone uses plastic - but those are all products, not creude material.  The only entities that use crude oil are refiners, who are now working at maximum capacity and unable to ramp up further production.  The demand for these end products persists [unless demand destruction occurs - a separate issue], so right now the price for the products is huge.  His rough example is that while Brent oil is USD70/bbl, the price for the products averages USD140/bbl - that "crack spread" is the highest he has seen in 30 years.   Meanwhile, Ukraine has been hammering Russian oil reserves and Russia's refining capacity and the earthquake in Venezuela took out part of their refining capacity.  Crude oil prices dropped when the "memorandum of understanding" was signed because a flood of tankers left the Strait of Hormuz, but without a continuing flow the price is edging back up and there is currently no reason for that to change.  When this conflict started, the U.S. and other countries started to harvest their strategic petroleum reserves, which are now getting low (some other countries have exhausted theirs or have never had petroleum reserves in storage).  If the U.S. continues to empty its strategic petroleum reserve to cover up the shortages of crude exiting the gulf, the potential scenario is catastrophic.

The long video also includes some discussion about how China (allied with Iran) also has control of much of the worlds critical metals, plus they are leading the world in energy storage (batteries) and in wind and nuclear technologies.  IMHO the future belongs to China, which staffs their administration with scientists.

Addendum:  Markets are now opening in Asia...


Addendum:  A nice chart of transits through the Strait of Hormuz, showing the initial "hot war," the MOU period, and the resurgence of hostilities.  I'll see if I can find an updated chart of strategic petroleum reserves.

Do you remember the "alphabet game" ?


My father's career was as a traveling salesman, driving five states selling electrical equipment to local utilities.  So when our family went on vacation, it was by car, not by plane.  We drove from Minnesota to visit family in Pennsylvania or Florida or Nevada, and on those seemingly endless days on the highway (most of them in the pre-interstate highway era) we played games, including the "alphabet game" which required one to find the letters of the alphabet consecutively on signs, license plates, etc.  Those with similar memories will appreciate this modern billboard posted by the Sign Appreciation Society on Facebook.

At some future time I want to write a post about Burma Shave signs.

How does music become "popular" ?

Do you ever get the sense that many of the so-called mainstream pop stars whose images you unwittingly encounter dozens of times a day aren’t as “mainstream” or “popular” as you’re told they are? Do you give one eighth of a fuck about Dua Lipa, Zara Larsson, Childish Gambino, Bebe Rexha, or Shawn Mendes? Does your mother? Your little cousin? Your boss? The person delivering your mail? Your barista? Have you (or has anyone close to you) ever spent real money on anything these artists are selling? Do you, or anyone around you, follow them with any interest in what they make or do?...

And Spelman said: “In the past, a label and management team would do a great job getting their artist on SNL or Tiny Desk or Triple J, post it, and then kind of wait, and the comments would come in: terrible cover choice, voice sounds terrible, all that. What we do at Chaotic Good with our management clients is this: the second the SNL performance drops at midnight, you should post one hundred times saying that was the best performance of the year. The question is how you do that at scale. It takes a lot of work and infrastructure, but controlling the narrative is really, really important.”...

This is precisely how contemporary digital-music marketing operates, less as targeted exposure or coercion and more as the quiet reconstruction of the conditions under which discovery appears to occur. Not by introducing music to listeners but by staging the conditions in which it feels as though it arrived on its own.
More details in the "Getting Shilled" article in the June issue of Harper's Magazine.

Just for fun: "Good Luck, Have Fun, Don't Die"


I watched this DVD from our library last night and thoroughly enjoyed it (rated it 3.5 on my 0-4 scale, which means "good enough to recommend" but not "worth watching again", which requires a 4.0).

From the trailer it should be evident that the storyline presents over-the-top craziness involving a future dystopic apocalypse - which is oddly enough a pleasant relief from scanning the internet for info re politics and the Gulf war.  I was going to call it a "screwball comedy" but that term I will reserve for Cary Grant, Katherine Hepburn, Rosalind Russell et al in Bringing Up Baby, His Girl Friday et al.

The premise here is that the protagonist is in a Groundhog Day loop trying to prevent a worldwide catastrophe triggered by social media and cellphones.  If you can roll with that, you can enjoy the movie.  Sam Rockwell is joined by Juno Temple (Ted Lasso, Fargo fifth season) and the perhaps underappreciated Haley Lu Richardson (superb in Columbus).

Two interesting numbers about teenagers

Percentage of Americans who were paid to babysit as teenagers: 56

Who say they would trust a teenager to babysit today: 11

Numbers from the June issue of Harper's magazine.  As phrased it's not clear to me whether the 11% is of Americans or of Americans who babysat as teenagers.  In either case the discrepancy is striking.

Addendum:  interesting comment by an anonymous reader: "Slight twist on the same idea: I don't trust adults not to sue me if my teen makes a mistake while babysitting.'

Fears of "weather modification"

A radar tower stands alone in northeast Oklahoma City, surrounded by a green field. It is one hundred feet tall and topped with a smooth, white orb. Hidden inside the orb, an antenna rotates while pulsing electromagnetic waves into the distance, waiting for a faint bounce to arrive back in the dish. It is not quite an all-seeing eye. The tower can identify hail, rain drops, a cloud of cicadas, the spiraling debris in tornadic winds from more than one hundred miles away. 

[On July 6, 2025] At 9:35 pm, a bearded man approached the radar tower and began to climb the chain-link fence around it.  As he reached the top bar, the bearded man paused to rock back and forth and lean his head back, yelling into the night sky some unheard complaint. He gazed around and the lens of a security camera caught his face, retinas glowing back in the dark.

On the other side of the fence, he got to work. With a hammer, he snapped open the latch guarding the radar’s million-watt power supply. There were control panels, switches, meters. He destroyed them all. Content that the tower had been disabled, he walked around the facility systematically destroying each security camera. It is unclear whether he understood that destroying cameras would not destroy the images they had captured of him. On a bicycle, he disappeared back into the night...

The following day, Michael Lewis Arthur Meyer, who is the leader of a militia named Veterans on Patrol, contacted media outlets and the Oklahoma City Police Department to take credit for the incident. He claimed that [Anthony Tyler] Mitchell was one of his followers, taking the direct action that Meyer had been threatening for months. The group believes that the latest generation of weather radar towers are “directed energy weapons” that the military have “pointed at the American people.” Meyer claimed that Veterans on Patrol would not stop at disabling one radar tower, that they had plans for taking down at least a dozen more.

In his statements to reporters at the time, Meyer insisted that his crusade was a divine one. The weather was being modified, there were powers out there that could control it, and this was against God.

“When the military plays God with the weather, they’re mocking our Heavenly Father,” he said.
The story about the "battle over weather modification" continues in the June issue of Harper's Magazine.

Interesting Swedish postal cancel


I've had this pair of stamps in my collection for decades, labeled "ventilator" cancels, which I assumed without research was a form of "disinfected mail."

Today when I checked for more information, I discovered that these "ventilations" were not designed to prevent the spread of contagious diseases, but rather to prevent the reuse of the stamps.  Here is some relevant information from the Swedish Postal Museum:
"The "ventilator" cancel (ventilatorstämpel) featured a specialized postmark wheel with built-in, fan-like rotating blades. When the postal clerk pressed the device onto a letter, the wheel spun and physically cut or punctured small, geometric slits directly into the paper fibers of the stamp. If anyone tried to steam or peel the stamp off the envelope to reuse it, the stamp would tear apart along those slits.  Because the security incisions resembled the radial slats of an air vent or ventilation fan, philatelists nicknamed it the "ventilator" cancel. Similar mechanical safety trials from that era included the bikupestämpel ("beehive" cancel) and the sÃ¥gtandsstämpel ("saw-tooth" cancel)."  
I have some beehive cancels I can post in the future.  Sawtooth ones are apparently exceedingly rare, presumably because they were used only for a short period of time and because anyone trying to remove the stamp to put it in a collection would have wound up with a severely damaged stamp.  The green 5o stamp on the right has a small triangular defect best seen when viewed with my digital microscope:

A history of disinfected mail


As soon as humans became aware that infectious diseases could be transmitted by fomites (inanimate objects), attention was directed to developing methods of disinfection. Postal and public health authorities had to deal with a wide variety of extremely dangerous infections (cholera, yellow fever, smallpox, leprosy, anthrax), and applied a surprising variety of techniques to letters and packages sent through the mails, beginning as early as the 15th century in Venice.

A very informative philatelic exhibit presents examples of how the U.S. has dealth with potentially dangerous items.  Shown at the top, for example, are two letters from locations where yellow fever was present; they have been punctured to allow fumigating agents to reach the inside of the envelope.  The bottom envelope in this image -


- had its corners clipped off so that formaldehyde gas could be introduced to kill smallpox.  Other letters and postcards were autoclaved or steam sterilized, which could be deleterious to the letters inside.

These precautions were not limited to the preantibiotic era.  In 2001 threats of anthrax attacks were made in the United States, and a variety of special precautions, including x-irradiation, had to be undertaken, beginning at this page of the exhibit and continuing for a dozen pages thereafter.  And these letters from Hawaii in 1900 show how holes were punched in the envelopes -


- so that sulfur fumes could be insufflated before they were sent from areas quarantined for bubonic plague.  Other examples are shown of disinfection of mail from the Hawaiian leper colony.

Philatelic exhibitions are conventionally mounted on a series of glass-fronted frames, with up to 16 letter-size pages in one frame, and in this case spread onto six frames.   This award-winning exhibit was created by William A. Sandrik of Arlington, Virginia.  The entire exhibit may be viewed at Exponet (frame 1, frame 2, frame 3, frame 4, frame 5, frame 6).

And those interested in philately (stamp and postal history collecting) should browse the Exponet site beginning at this index page.  Over 600 exhibits are accessible, on a huge variety of topics, in a wide variety of languages.

Reposted from 2011 because of its timely subject matter.   Today a New York Times article addresses the question of transmission of coronavirus by mail:
A representative for the U.S. Postal Service was unwilling to discuss current sanitization protocols. But the agency’s website reports that the only mail items receiving treatment are letters and parcels sent to ZIP codes beginning in 202, 203, 204 and 205, which serve federal government agencies in Washington, D.C. In a process that began shortly after the 2001 anthrax attacks, the Postal Service sends mail destined for those ZIP codes to New Jersey, where they are put on a conveyor belt and passed under a high-energy beam of ionizing radiation that kills bacteria and viruses. The letters and packages are then “aired out” for a while, before being forwarded to their destinations. The paper is left slightly faded and somewhat crispy, but sterile.

Should mail irradiation be extended beyond these exclusive ZIP codes, to help prevent the spread of the coronavirus? On CBS News’s Face the Nation on Sunday morning, Scott Gottlieb, the former commissioner of the Food and Drug Administration, warned that SARS-CoV-2 could potentially be transmitted by contaminated objects. “This is a sticky virus,” he said. The structure of the coronavirus’s protective envelope helps it bond tightly to certain surfaces: skin in particular, as well as fabric and wood, but also plastic and steel...

David Partenheimer, a spokesman for the Postal Service, noted that the surgeon general, Dr. Jerome M. Adams, along with the Centers for Disease Control and the World Health Organization, has “indicated that there is currently no evidence that COVID-19 is being spread through the mail.”..

Then again, contact transmission is notoriously difficult to study and document...

This would be a MAJOR escalation in the war


When you see the words Bab al Mandab Strait in mainstream news sources, pay close attention.  This is the southern exit from the Red Sea and a major route for Saudi Arabia to export its oil.  If the Houthis effectively close it, expect the price of Brent and WTI to reach new highs quickly.

The world economy better pray that the U.S. generals can convince Trump not to escalate the bombing of Iran to civilian sites.

Apparently some people hate (or love) semicolons

TYWKIWDBI loves semicolons, so I was surprised and intrigued by the content of an article at Literary Hub
"Here is a lesson in creative writing. First rule: Do not use semicolons. . . All they do is show you’ve been to college. "(Kurt Vonnegut)

"I suppose this is a trivial matter but I do want to object to the maddening fuss-fidget punctuation which one of your editors is attempting to impose on my story. I said it before but I’ll say it again, that unless necessary for clarity of meaning I would prefer a minimum of goddamn commas, hyphens, apostrophes, quotation marks and fucking (most obscene of all punctuation marks) semi-colons. I’ve had to waste hours erasing that storm of flyshit on the typescript" (Edward Abbey) [In reference to The Monkey Wrench Gang and preserved in Postcards from Ed: Dispatches and Salvos from an American Iconoclast]

"With educated people, I suppose, punctuation is a matter of rule; with me it is a matter of feeling. But I must say I have a great respect for the semi-colon; it’s a useful little chap." (Abraham Lincoln)

"I don’t have a gun and I don’t have even one wife and my sentences tend to go on and on and on, with all this syntax in them. Ernest Hemingway would have died rather than have syntax. Or semicolons. I use a whole lot of half-assed semicolons; there was one of them just now; that was a semicolon after “semicolons,” and another one after “now.”" (Ursula LeGuin) [from The Wave in the Mind: Talks and Essays on the Writer, the Reader and the Imagination]

U.S. to screen soldiers for testosterone deficiency


The US defense secretary unveiled plans for a new screening program for testosterone deficiency among troops that will work to ensure service members have the “right testosterone levels” to perform at their optimal conditions in a video posted to X...

“Warfighters” aged 30 and above will undergo annual tests as part of their health assessments, while those under 30 can choose to opt in, Hegseth said. Treatment, including testosterone replacement therapy, is voluntary and aimed at “restoring and optimizing” natural capabilities...

Hegseth is not the first member of the Trump administration to address the so-called “crisis” of low testosterone, or “low T”. Robert F Kennedy Jr, the 72-year-old health secretary, has spoken about injecting testosterone as part of his personal “anti-ageing regimen”. In October, he warned, without evidence, that today’s American teenagers have “50% of the testosterone of a 65-year-old man”.

Testosterone, and concerns about a shortage thereof, has become a political fixation on the right. Alternative media commentators such as Tucker Carlson have decried a crisis of masculinity in films such as The End of Men, while influencers promote “T-maxxing” and direct-to-consumer testosterone injections...

According to research published in the journal Social Science & Medicine, young men are being aggressively targeted online by influencers and wellness companies promoting hormone tests and treatments as essential to being a “real man”, despite screening for low testosterone being medically unwarranted in most people in this age group.
I do hope there is one sane person in the armed forces administration who will understand that half the men in the world have testosterone levels below average.

"When she turns eight, they will take her"

Sima* is 18, but has already given birth four times. Her youngest is a newborn, the eldest is four. Sitting with her children in their mud-brick room in Badghis province, Sima says: “After the Taliban entered the country, I had just finished the sixth grade and was supposed to start the seventh. But two months later, my father pressured me immensely to marry my cousin. After being beaten by my father several times, I was forced to accept.”...

Interviews with workers at one public hospital in northern Afghanistan revealed that 42 underage girls gave birth in the first five months of this year. Six were in their second pregnancy. Five had ectopic pregnancies – a leading cause of maternal deaths – and 18 had caesarean sections. Two died, though their babies survived...

They are victims of a growing trend toward child marriage, driven by Taliban policies legalising the practice and forcing girls out of school, combined with a deepening humanitarian crisis in which families are forced to sell their daughters to pay debts or buy food...

Some families falsely believe the younger the mother, the healthier and smarter the child. Mothers who are still children themselves often haven’t completed their physical or psychological growth and face higher risk of severe bleeding, anaemia, miscarriage, obstructed labour and premature birth, along with a greater likelihood of a low-weight or unhealthy infant...

Shabnam says families often resist caesarean section, believing they limit future pregnancies. Two young mothers in her care recently died in childbirth because their husbands refused to permit one...

The other three families interviewed for this report, all in western Afghanistan, say their daughters had been used to settle debts – money paid in advance, the daughters to be handed over later. Three of the girls are still under 10, unaware of the future that has been planned for them...

When she turns eight, they will take her from us,” says Golnar. “They gave 100,000 afghani upfront, and they will give another 100,000 after they take the girl from me. We gave it directly to the creditors for the debts.” She worries about her granddaughter’s future, remembering girls sold years ago in her neighbourhood: “They have no future. Whether they leave us to burn in a fire or face anything else, we will not know.”

More gleanings from Facebook

Math puzzle


I found this on Facebook without an answer posted there.  I've put my answer in the comments but am not sure about it.  Would appreciate insight from readers.

Trichromacy vs. dichromacy


Not sure I trust the image, but the principle appears to be valid.
Until the 1960s, popular belief held that most mammals outside of primates were monochromats. In the last half-century, however, a focus on behavioral and genetic testing of mammals has accumulated extensive evidence of dichromatic color vision in a number of mammalian orders. Mammals are now usually assumed to be dichromats (possessing S- and L-cones), with monochromats viewed as the exceptions.

The common vertebrate ancestor, extant during the Cambrian, was tetrachromatic, possessing 4 distinct opsins classes. Early mammalian evolution would see the loss of two of these four opsins, due to the nocturnal bottleneck, as dichromacy may improve an animal's ability to distinguish colors in dim light. Placental mammals are therefore – as a rule – dichromatic.

The exceptions to this rule of dichromatic vision in placental mammals are old world monkeys and apes, which re-evolved trichromacy, and marine mammals (both pinnipeds and cetaceans) which are cone monochromats. New World Monkeys are a partial exception: in most species, males are dichromats, and about 60% of females are trichromats, but the owl monkeys are cone monochromats, and both sexes of howler monkeys are trichromats.

Trichromacy has been retained or re-evolved in marsupials, where trichromatic vision is widespread. Recent genetic and behavioral evidence suggests the South American marsupial Didelphis albiventris is dichromatic, with only two classes of cone opsins having been found within the genus Didelphis.

The Al Naslaa rock in Saudi Arabia


Image cropped for size from the original posted at Live Science, where you can read about the controversies about the formation of the gap.  See also Geology Science, which offers this image:


Personally I don't believe this formed as a result of a natural fault or joint.  The rock itself is sandstone, so I would bet that humans created the gap using rope with perhaps added abrasives, perhaps just as a whimsy.

A subtle and wry comment on current events


Image of Haley Joel Osment from his Oscar-nominated performance in the movie The Sixth Sense.  Updated with a cultural reference to current U.S. politics.  The scene occurs at about the 4-minute mark of this excerpt - but beware that this is a major spoiler for those who have not seen the movie.

I bet I could win bar bets with this factoid

Boston Fourth of July aerial celebration, 2026


My old friends back in the Boston area have told me that this year's show combining drones and fireworks was truly spectacular.

A new fashion statement: the "divorce ring"

"Shimmering on Deb Marino's finger are diamonds set in an eye-catching gold ring.  "Of course it's a middle finger ring, because, why not?" the Florida-based blogger says on her Tiktok feed.

Getting rid of her engagement ring would have suggested a regret the 34-year-old doesn't feel - after all, her marriage brought her daughter. Even just not wearing it would have felt like a waste. "I didn't want it locked away in a box," she says. "Diamonds are precious."..

Deb is part of a rising trend promoted by jewellers around the world of women marking a new chapter in their life with a new statement piece: the divorce ring.

Deb had the diamond from her engagement ring set at one end of an open circle and added a new sapphire to represent her daughter to the other end. It cost $3,000 (£2,245). It's a sizeable sum to part with when divorces can be expensive.  Ring resale values tend to be only around 30% of the original price so for many the trend of giving their old jewellery a new life feels a better investment."

Fiber-optic materials in Ukrainian birds' nests

Yana Hrynko, senior researcher of The National Museum of the History of Ukraine in the Second World War, shows bird’s nests made partially with fragments of fiber-optic lines that were found by a Ukrainian serviceman on the front line and then passed to the museum, in Kyiv, Ukraine, on June 23, 2026. Both Ukrainian and Russian troops use drones controlled via long lines of optic fiber to bypass electronic warfare jamming, leaving miles of ultra-thin lines tangled in trees and scattered across the land in Ukraine’s frontline regions.  (Valentyn Ogirenko / Reuters)

Here's the video from Reuters on this topic - with a tip of the blogging cap to an unidentified reader.

An interesting NOVA program on "desert kites"


This one is many months old, because I save them to a DVR and watch whenever.  I believe what I've embedded above is full-length rather than a teaser trailer.

I didn't watch it when it came out because I thought the "desert kites" were quite obviously the terrestrial equivalent of fish weirs in coastal environments.  The interesting reveal to me was that the ancient people constructing these were able to create "death pits" using walls of just the right height so that an antelope's vision wouldn't see the presence of the pit, which was lined with smooth stones to prevent escape.  Basically like creating a "head-smashed-in buffalo jump" where there were no natural cliffs.  And these were very early people from the Neolithic era.

The video also takes advantage of modern computer image generation and drone photography in rather effective ways.  NOVA programs have always been of the highest quality.

Ethnicity map of the United States


To celebrate the nation's 250th birthday, the New York Times has created an impressive interactive map depicting the self-reported ethnicity of U.S. citizens as they recorded such in 2019-2024 U.S. Census.  Responses rhat included a race but not a specific origin group are not included.

In the interactive map, you can zoom in to drill down to specific subregions, apparently defined by census data rather than county borders:


And there is a map from the time of colonization:
