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:
