Pucker up

The price of in-flight snacks
"A passenger was removed from a Breeze Airways flight that traveled from New York to Florida after allegedly taking snacks from the beverage cart without paying, airline officials said...
Breeze sells a variety of snacks on board, including $5 options such as gummies, potato chips and popcorn, as well as $10 premium items including ramen noodles and cheese trays.
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
"Pete Hegseth announced Wednesday that the Department of Defense will offer testosterone deficiency screening for soldiers 30 and older.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.”

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.

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.

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.

Chipmunks
I first noticed the rodent activity last week (image above) at the place where the driveway meets the garage, so I replaced the gravel in the burrow and made a mental note to do something about it, but by yesterday (below) the process was obviously in an accelerated phase.
The quickest response would be to push all the dirt and gravel back down and then seal the top with an expanding foam, but I was reluctant to possibly convert the burrow into a live burial, so instead I got out our smallest Havahart trap, baited it with a piece of chicken teriyaki, and waited. Within a couple hours the malefactor was in the trap, and I drove him/her to a new homesite near fields and prairie about a mile away.
Then I reset the trap, not sure if this was one guy or possibly two. I captured a second one before evening and drove it over to where the first was released. Then I realized that I don't know that the ones I trapped are a mated pair and the occupants of the hole or just wandering neighborhood residents, so I decided to look up some info on their ecology and when they have their litters. Found this nice infographic -
That was new information for me. I did not realize that common chipmunks would create multiple entrances to their hidey-holes. Now I'm thinking that the risk of sealing a chipmunk family into a live burial horrorshow is unlikely, and that I can just go ahead with the cleanup and closure.
But one advantage of having a blog full of well-read and diversely-experienced readers is that sometimes I can call for help. So I'd appreciate advice from others with backgrounds in rodentology, mammalogy, pest control, or house maintenance.
Before leaving, I'll insert several tidbits from the Wikipedia entry:
The common name originally may have been spelled "chitmunk", from the native Odawa (Ottawa) word jidmoonh, meaning "red squirrel" (cf. Ojibwe ajidamoo). The earliest form cited in the Oxford English Dictionary is "chipmonk", from 1842. Other early forms include "chipmuck" and "chipminck", and in the 1830s they were also referred to as "chip squirrels", probably in reference to the sound they make. In the mid-19th century, John James Audubon and his sons included a lithograph of the chipmunk in their Viviparous Quadrupeds of North America, calling it the "chipping squirrel [or] hackee". Chipmunks have also been referred to as ground squirrels, (although the name "ground squirrel" may refer to other squirrels, such as those of the genus Spermophilus).Eastern chipmunks, the largest of the chipmunks, mate in early spring and again in early summer, producing litters of four or five young twice each year... Chipmunks construct extensive burrows which can be more than 3.5 m (11 ft) in length with several well-concealed entrances. The burrows are complex and include plugged entryways, nseparate compartments for nesting, multiple food chambers, side pockets and escape routes. The sleeping quarters are kept clear of shells, and feces are stored in refuse tunnels.
11 stars on this eagle
"President Donald Trump has posted what appears to be a doctored image of a large, golden eagle attached to the White House's Truman Balcony on social media—the latest in a series of altered or AI-generated images the president has shared in recent months...According to CNN, the image has details in its metadata that indicate it was created with Google AI.The outlet also noted that the image did not appear to be real because of differences between the railings in the picture and the real-life Truman Balcony.The shield in the image also has 11 stars, whereas the traditional version has 13 to reflect the 13 states at the time the United States was founded."
The original digital artist may have used 11 stars to represent the 11 states in the Confederacy.

"The Life of Chuck"
Using the Siskel/Ebert grading system, this movie gets two "thumbs up" from me. I've embedded the official trailer above, but it is so spare that it doesn't offer much of the sense of the movie, which is perhaps better conveyed by this excerpt, in which Chiwetel Ejiofor's character explains Carl Sagan's "cosmic calendar" to his ex-wife:
But for a full appreciation of the movie, I would recommend this 14-minute longwatch analysis and commentary:
Some will consider that commentary to be full of "spoilers" but in this case I think the reveals are appropriate in order to understand what is happening in the opening sequence when the "world" is coming to an end.
What impressed me was author Stephen King's choice of a glioblastoma multiforme as the cause of Chuck's death. Had he died in a vehicular accident or from other sudden trauma, the "universe" in his head would have just winked out. The glioblastoma, by contrast, slowly snakes its way through Chuck's head, and as it destroys or replaces his memories of California for example, the California of the universe slides into the ocean. The characters in his head can "see" their impending death and have time to react in their personal lives.
When the key monologue in the movie is delivered by Chuck's 6th grade teacher, I was surprised and delighted to see that the actress in that role - Kate Siegel - was the same actress who delivered the most important monologue in the miniseries Midnight Madness ("what happens when you die"), which was also directed by Mike Flanagan.
When the movie was released in 2025 it received mixed reviews from critics, but notably won the People's Choice Award at the Toronto International Film Festival - a distinction that normally leads to a nomination for the Academy Award for Best Picture - but that did not happen in this case, and I think the movie has been sadly overlooked.

A link for lovers of movies: The Criterion Closet
For much of my adult life I have been a fan of the Criterion Collection. About fifteen years ago I did subscribe to the Criterion Channel in order to stream their movie collection on demand, but I found the interface clunky, especially for fast-forwarding, seeking etc. I dropped that subscription after realizing that our local public library has over a thousand Criterion Channel movies available on DVD and Blu-ray.
There is a physical (and a mobile) Criterion Closet containing all the movies. This week I realized there is an app to access that closet. At the link you can view and interact with that closet either in a mockup of the physical setting ("closet view") or in a list view (screencap embedded above). From that app you can access all the movies via your subscription or purchase them. But more importantly for the average reader here, you can access trailers for virtually all of those 1,327 movies.
Then I borrow the DVDs from the library.

A reflecting pool cocktail
There are a seemingly endless number of memes on the reflecting pool disaster. Readers are welcome to provide links to their favorites in the Comments. I thought this one posted by Sarah Dahlinger on Facebook was nicely done.
I've seen a lot of brilliantly made craft cocktails dedicated to the Reflecting Pool this past weekend, and I thought, something was missing. Something wasn't right.They didn't quite capture the level of class and sophistication that our Reflecting Pool currently has, so here's my version.To start, line your glass with a blue fruit roll up. Then you're going to need:2 oz rum4 oz juice that is kinda yellow (pineapple, mango, orange, lemonade, whatever you like)1 oz blue curacao (you can adjust for color)Garnish with lime zestThe yellow and blue liquids make a lovely shade of algae and the rum eventually melts the blue fruit roll up, which is, IMHO, the best part.

New technology for warfare: gyrocopters and paragliders
"They appear after midnight, slowly crossing Myanmar’s skies. The motorised paragliders are improvised aircraft, suspending small metal frames from brightly coloured sails. They drift over a patchwork of villages, farmland, forests and winding rivers.Each “paramotor” has two or three soldiers strapped in – one piloting, the others holding the bombs. Their craft are powered through the sky by small, rattling engine propellers, heading towards the lowland villages. Finally, switching their engines off to glide low and near silently through the dark, the men throw their explosives.The destruction is immediate and devastating. Attacks can last several minutes, with bombs weighing up to 16kg (35lb) each dropped in quick succession. Homes are torn apart, schools and religious buildings destroyed – and civilians killed or injured as they sleep. The villages descend into panic and confusion, with families fleeing into the darkness and emergency workers digging through debris for the wounded.“People try to run to the bomb shelters. But there is usually not enough time,” says Lwan Thu, an activist in the Sagaing region, which has been heavily bombed by the paramotors. “There are scores of dead and injured after the strikes.”...“We’re facing constant strikes by these new aircraft,” says Lwan Thu. “They are using them to attack everything – civilians, hospitals, religious ceremonies, residential homes.”...Unlike military jets, these lightweight aircraft require little infrastructure, use small amounts of fuel, are cheap to buy and are hard to track, evading detection from early-warning systems. Soldiers can be trained to operate them in a matter of days, rather than the years needed to fly conventional aircraft.Buying paragliders, which are widely available commercially, also allows the junta to evade international sanctions targeting the military’s access to arms...One attack on a Buddhist festival at a primary school in October killed at least 24 people, including three children, and wounded 61. A witness told Fortify Rights, a human rights organisation: “[The paramotors] had no lights … I didn’t hear any engine sounds at all.“We later found out that the paramotors turned off their engines when they approached the school compound and glided over with their parachutes.”One woman told Agence France-Presse in the aftermath: “Children were completely torn apart.” The next day, she said, they were still “collecting body parts”.

Prefix of the day: "pene"
This rock was identified at the whatsthisrock subreddit as a "penecontemporaneous deformation structure." It apparently is such a commonly-used term that it is shortened by users to "PCD." There is excellent informed discussion at the link to explain that PCDs are formed when sedimentary material is deformed during deposition ("contemporaneously"). Lots of further details at Geological Digressions.
I thought the rock was cool, but what grabbed my attention was the fact that I am an English major almost 80 years of age and I'm seeing a prefix that is not in my wheelhouse.
Onward to the Wiktionary entry for "pene":
Almost the thing or quality expressed by the root, as peneplain (almost a plain), peninsula (almost an island), penultimate (almost the last), penumbra (almost in shadow).
Wow. Three words I've used for essentially all my adult life without appreciating their common prefix.

The etymology of "soccer"
This will be my only post relevant to this year's World Cup.
"... in its early days, football was a very "posh" sport. "The people who founded the Football Association in England in 1863 were Oxford graduates who had attended elite public schools," he said. The game played under Football Association rules became known as "association football", wrote John M Cunningham in the Encyclopaedia Britannica. The name also helped distinguish it from another popular sport: rugby...Among wealthy university students in the 1880s and 1890s, there was a habit of shortening words and adding "-er" to the end, creating a kind of slang. "So instead of saying 'breakfast,' they would say 'brekker'." Applied to rugby, they would call it "rugger."..It appears that these inventive students took "soc" from the middle of the word "association" and added "-er," producing "soccer". "Obviously, no-one knows for certain, but what people are sure about is that it comes from Oxford. There are many documentary sources confirming that it was a word coined by students there."

Postal history of the Telemark coast of Norway
The video is a full-length recording of an hour-long presentation at the Boston 2026 World Exposition of Philately. The Telemark postal district is situated west of Oslo, and the coast extends from Skien on the north to Kragero on the southwest. This presentation discusses postal history of this region up through the end of the 19th century. The information will be of most interest to serious philatelists or to others interested in Scandinavian history.
One item will also be of interest to anyone who has a relative or friend whose last name is Odegaard. When the Black Plague arrived in Norway in 1349, approximately 2/3 of the population died. Some of those who survived moved to the abandoned farms. "Odegaard" is Norwegian for "abandoned farm." You learn something every day.

The dark side of Beatrix Potter
Beatrix Potter, despite the efforts of Graham Greene and many others, is still tarred with a certain National Trust tweeness, even though her tales of murder and separation are among the darkest if funniest books ever written. Those books would be nothing without their illustrations, and in her masterpiece, The Tale of Samuel Whiskers, she should have firmly established herself in a direct line of gothic illustrators stretching from Fuseli and Blake to Mervyn Peake. This picture, of Tom Kitten being turned into a roly-poly pudding, is among the funniest yet also most terrifying illustrations of the 20th century.[Martin Rowson]Text and image from a gallery of writers' favourite classic book illustrations posted at The Guardian. I was unaware of this supposed "dark side," but found two relevant commentaries, the first in a Guardian column in 2006:
The Tale of Tom Kitten does not teach adventurous disobedience; rather it tells us that disobedience is punished with violence. Or this, at least, is what I thought when I flung the book across the room in disgust (only, intrigued, to pick it up again soon after).
Tom Kitten and his siblings are smacked and sent to bed for their notional disgrace. Worse yet, when they continue romping in the bedroom, they disturb what Potter calls the "dignity and repose of the tea party". Can the reader who finishes the book rest easy that subversive Tom has triumphed? No: the fact is Tabitha Twitchit thrashes her children for losing their clothes. Imagine what grisly fate will befall them when she stomps upstairs from her ruined tea party! To her credit, Potter leaves the sadism of this neurotic to the imagination.
So far, my daughter and I have found Beatrix Potter to be a proselytiser for sadistic punishment, a sartorial fascist, a property-upholding reactionary, an obsessive-compulsive nutcase (or rather nut-kin) and, conceivably, a bystander in the face of an intolerable natural dystopia that, with her sick (though gifted) writer's mind, she culpably imagined. As an adult reader, I must say, I'm beginning to like her.And this at Wig and Pen:
Use discretion when reading Beatrix Potter to your children. In almost every Potter tale, her main characters—everyone from Peter Rabbit to Jemima Puddle Duck—flirt with mortal danger...I have no personal insights to offer, not having read any of the canon. Knowledgeable readers should feel free to offer comments.
The Silence of the Lambs has nothing on Potter’s description of the house and yard [in The Tale of Mr. Tod]:
The house was something between a cave, a prison, and a tumbledown pigsty. There was a strong door, which was shut and locked. [In the yard] there were many unpleasant things lying about that had much better have been buried: rabbit bones and skulls, and chickens’ legs and other horrors. It was a shocking place and very dark.Peeking through a window, Benjamin and Peter discovered that Tommy Brock had retired for the night after stashing the brood—still alive and kicking--in an oven for safekeeping and for his next meal.

Cloche hats
The cloche hat is a fitted, bell-shaped hat that was popular during the 1920s. (Cloche is the French word for bell.) Caroline Reboux is the creator of the cloche hat.Photo via the wonderfully-named My Ear-Trumpet Has Been Struck by Lightning. Too bad it has now gone inactive (but still browseable).
Cloche hats were usually made of felt so that they conformed to the head. The hat was typically designed to be worn low on the forehead, with the wearer's eyes only slightly below the brim. By 1928-1929, it became fashionable to turn the brims on cloche hats upwards. This style remained prevalent throughout the early 1930s until the cloche hat became obsolete around 1933-1934.
Often, different styles of ribbons affixed to the hats indicated different messages about the wearer. Several popular messages included: An arrow-like ribbon which indicated a girl was single but had already given her heart to someone, a firm knot which signaled marriage or a flamboyant bow which indicated the wearer was single and interested in mingling...
Reposted from 2010 (!!) after watching Agatha Christie's Seven Dials miniseries last night and seeing Mia McKenna Bruce in the starring role of a 1925 character:
Personally I would be happy to see this hat style come back into fashion. It looks very comfy and reasonably sensible in a world concerned about solar skin damage.
Secretariat at the Belmont Stakes in 1973 - his "tremendous machine" performance
Over 5,000 winning tickets were never redeemed because the holders valued them more as souvenirs than for their cash value.

Addendum: A tip of the blogging hat to reader demenace07, who offered this link with more information about the economics of uncashed winning tickets for a more recent race:
Some enterprising horse bettors are selling their tickets on eBay, where such tickets are selling for $20 to $30. Other sellers bought up many of the cheapest Belmont Stakes gambling tickets. One seller is selling a lot of 500 such tickets. Another is selling 150 tickets in a lot.Tickets for the Triple Crown wins of Secretariat (1973) and Seattle Slew (1977) sold for big money on the collectors market.Rovell said that the tickets are simply worth more to collectors than the cash-in price. He said, “Whether you want to keep it for your memory or resell it, it’s worth ten times more than if you cash it in. So people are making good bets.”
Reposted again in 2026 because I found it while looking for other stuff. I don't follow or even enjoy watching horse racing, although I did see some dressage events during my years in Kentucky, but this race is so iconic that it's worth preserving here in the blog.
Some observations re SpaceX
"By Friday, however, the macro narratives were entirely overshadowed by the excitement of the SpaceX IPO. It’s an IPO that will go down in history for a remarkable combination of reasons—from its sheer scale ($75 billion, almost three times the previous largest IPO) and the $1.8 trillion valuation (which places it immediately, on day one, as the seventh-most-valuable US company), to challenging the traditional playbook on investor allocation, price discovery, and fast-tracked index inclusion. It has also triggered an unprecedented wave of wealth creation, from Elon Musk’s new trillionaire status to some 4,400 millionaires minted among the firm’s current and former employees. All this for a company that generates no profits, is highly valued, and carries enormous key-person risk."

Why mosquito eggs float
This hand-coloured scanning electron micrograph was the favourite of the jury in the section "Best Scientific Image". The image shows the surface of a mosquito egg (from Culex pipiens), which generates a water repellent network by connecting microscopically small structures to trap a thin layer of air. The vitally important structures avoid immersion and enable the egg to float and aggregate with neighbouring eggs.The website of photographer Martin Oeggerli.

What's wrong with people nowadays?
"A space in Mankato that promotes reflection and healing for families who have lost a child has been vandalized, according to the nonprofit in charge of the memorial.The nonprofit behind the One Bright Star memorial at Victory Drive and E. Main Street said on June 5 that someone in recent days broke off a large landscape rock, damaged a plaque and threw both of them into the memorial’s pond...One Bright Star was founded in 1998 by four mothers who each experienced the death of a child, and the memorial was completed in 2003. It includes a shallow pond centered by a large star sculpture and a wall with paver bricks in remembrance of children who have died."
"The police in Boston are searching for two boys who they said flashed a handgun at a pair of children running a lemonade stand on Wednesday and stole... cash from a bright pink lockbox...Tiffany Byrne, the aunt of the two children working the lemonade stand, said that about $80 was taken...Ms. Byrne said her nephew, David, 12, and niece, Juliette, 11, “were pretty shaken up” but otherwise unharmed. She said she believed the robbers were wearing masks and were around middle-school age."

Studying whiskers on an elephant's trunk
This is the sentence that piqued my curiosity:
"Haptic researchers discovered a difference of two orders of magnitude in the elasticity of the thousand whiskers of an Asian elephant's trunk as they progress from the base to the tip."
The sentence was one of the "Findings" listed in the May 2026 issue of Harper's Magazine (this recurring feature is a wonderfully eclectic potpourri of scientific observations). The source was not provided, but a brief search led me to the arXiv of Cornell University and to the source text: "Functionally graded keratin facilitates tactile sensing in elephant whiskers." The research was conducted at the Max Planck Institute in Stuttgart. Here is the abstract:
Keratin composites enable animals to hike with hooves, fly with feathers, and sense with skin. These distinct functions arise from variations in the underlying properties and microscale arrangement of this natural polymer. One well-studied example is mammalian whiskers, elongated keratin rods attached to tactile skin structures that extend the animal’s sensory volume. Here, we investigate the non-actuated whiskers that cover Asian elephant (Elephas maximus) trunks and find they are geometrically and mechanically tailored to facilitate tactile perception by encoding contact location in vibrotactile signal amplitude and frequency. Elephant whiskers emerge from armored trunk skin and shift from a thick, circular, porous, stiff root to a thin, ovular, dense, soft point. This smooth transition enables interaction with widely varying substrates, reduces wear, and increases the vibrotactile signal information generated during contact. The functionally graded geometry, porosity, and stiffness of elephant whiskers tune the neuromechanics of trunk touch, facilitating highly dexterous manipulation.
The non-scientist reader will want to skip down to the Conclusions to get a sense of the "why":
Biological functionally graded material composites like elephant whiskers can inspire engineered devices that use functional gradients to achieve specific capabilities ranging from fatigue reduction to signal power increases. One of the first animal stiffness gradients discovered was the beak of the Humboldt squid, but mimicry of this stiffness gradient in soft materials posed a considerable manufacturing challenge at the time of this discovery. Recent advances in multi-material 3D printing enable unprecedented control over the deposition of materials with widely varying mechanical properties; cutting-edge inkjet systems create monolithic parts from materials with elastic moduli that span three orders of magnitude. Recent characterization of composites built from these materials enables inverse design, whereby one achieves desired system properties such as stiffness, toughness, and frequency response by prescribing both geometry and constituent materials at the microscale. Fields ranging from material science and neuroscience to haptics and bio-inspired robotics rely on signal processing through material interfaces, and functional gradients have significant potential to enable programmable signal shifts tuned to specific use cases.
Back in the 1970s when I began my postgraduate science research, United States Senator William Proxmire (a Democrat!) was ridiculing bench researchers for publishing what he considered to be trivial scientific findings. He created a "Golden Fleece Award" to demean such research. Some of the research mocked at that time was probably truly trivial and wasteful of public resources, but the luddite attitude was unfortunate, and the humor involved may have carried over to influence public opinion of science. In those years I was studying the effect of serum complement and Protein A on the clearance of staphylococci and gram-negative bacteria from BALB/c mouse lungs; fortunately I was well below his radar.
I'm posting this now to make note of the "why" of studying elephant trunk whiskers. Mother Nature has been doing hard science for millennia, and finding out how she achieved results can guide humans in an endless variety of quests.

An interesting Sudoku variant
In this variant the numbers in the dotted "cages" have to add up to the designated total (without duplication within the cage), and the numbers in the "thermometers" have to rise, with the lowest in the "bulb" of the thermometer. Otherwise normal Sudoku rules apply.
You can play this grid online here, where there are the standard tools for entering "possibles" and for checking the validity of your entries as you go along. I used the latter feature regularly, and managed to fill in the grid in 64 minutes without blind guessing.

College students who cannot read
Excerpt from an article in The Chronicle of Higher Education:
"Six weeks into the term, I assigned my rhetoric and writing students a 20-page article. It was the same length I had assigned for five years and the same length I had read without complaint as an undergraduate a decade ago. Not one student finished it.When I asked why, a student answered honestly: It was too long, and she kept losing track of what the paper was about. This was not a remedial class: These were students who had cleared the admissions process and written essays good enough to get them here. Yet a routine academic reading assignment had defeated them.Every generation of professors has complained that their students cannot read. The lament is usually overblown, but data have caught up to anecdote, and what I am seeing in my classroom is no longer a hunch. There is a measurable, generational collapse in sustained reading and writing, and the academy is responding to it with improvisation and exhaustion rather than the structural overhaul it requires.In February 2024, Adam Kotsko, who teaches in the Shimer Great Books School at North Central College, wrote in Slate that students who once handled 30 pages of reading per class meeting now seem “intimidated by anything over 10 pages and seem to walk away from readings of as little as 20 pages with no real understanding.” Crucially, he added that this is “not a matter of laziness on the part of the students” but of underlying skills they were never given a chance to build.The Chronicle of Higher Education’s 2024 investigation found the same pattern across institutions as different as the Stevens Institute of Technology and Wellesley College, where the average SAT exceeds 1400. Nicholaus Gutierrez, an assistant professor at Wellesley, told The Chronicle that the baseline for what students consider a reasonable amount of work has dropped so noticeably that he has cut his readings accordingly; a 750-word essay now strikes many students as long. At Stevens, the science and technology studies associate professor Theresa MacPhail described following the mantra of “meet your students where they are” for so long that she has begun to feel “like a cruise director organizing games of shuffleboard.”Worse, the national data tell the same story in colder language. On the 2011 National Assessment of Educational Progress (NAEP) writing assessment, which is the most recent comprehensive writing benchmark, only 24 percent of 12th graders reached the Proficient level, and just 3 percent reached Advanced; another 21 percent scored below Basic. The reading side of the ledger is worse, and getting worse fast: The 2024 NAEP results released in September 2025 show 12th-grade reading scores at the lowest level recorded since the assessment began in 1992. Thirty-two percent of 12th graders now score below NAEP Basic in reading, meaning that, in the assessment’s own language, they likely “cannot draw general conclusions based on concepts presented explicitly in a text.” And yet more than half of these same seniors reported being accepted to a four-year college. That last sentence is the whole problem in one line: We are admitting a cohort that cannot read at a college level and are pretending otherwise.

Ending a movie with a preposition
Last evening while trying to avoid doomscrolling I browsed some movies recorded on my DVR. I noticed that the dialogue in The Maltese Falcon ends with a preposition.
I found some commentary on the phrase at Blog of the Darned:
To be fair, the quote is based on a quote from Shakespeare:Prospero:...Leave not a rack behind. We are such stuffAs dreams are made on; and our little lifeIs rounded with a sleep.The Tempest Act 4, scene 1, 156–158Also "The stuff that dreams are made of" did not appear in Dashiell Hammett novel. Humphrey Bogart reportedly suggested the line to John Huston, and they went with it. Bogart was a stage actor on Broadway before turning to film, so I presumably he was familiar with The Tempest.
I'm not a rigid prescriptivist regarding usage of the English language, but last night I wondered whether any other major motion pictures end the dialogue on a preposition. A quick search of "last lines" mentions "And then I woke up" from No Country for Old Men, but in that case it would be an adverb (it's also not a preposition in "I'm ready for my close up."
There are probably many such examples. If there are movies with Minnesota characters, they might end a scene asking "are you coming with?"
I offer the challenge to the readers here. Not just any movie sentences ending with prepositions, but final words spoken in a movie.
