Deciding how to power a CubeSat is one of the greatest challenges when designing a modular spacecraft. Tradeoffs in solar panel size, battery size, and power consumption levels are all key considerations when selecting parts and mission architecture. To help with those design choices, a paper from researchers in Ethiopia and Korea describes a new machine-learning algorithm that helps CubeSat designers optimize their power consumption, ensuring these little satellites have a better chance of fulfilling their purpose.

Bill Maher’s latest news-and-comedy shtick (8½ minutes) deals with “Trump Devotion Syndrome”:  the sycophancy that imbues the cowards of America who don’t want to offend the Orange Man.  Lots of Presidential rump osculation here! Putting his image on Mount Rushmore and on American currency? But of course!

Oh, and there’s the “transgender mice” he mentioned.  (“We were splicing their genes, not making them compete in women’s sports.”) All in all, this bit is what the kids say is a “sick burn” for MAGA.  And Maher is peeved!

John McWhorter and journalist Rikki Schlott are there, too.

This is a good one; don’t miss it.

Here you go: the 18 celebrity ailurophiles featured, including photos and videos of their moggies. They include Taylor Swift (of course), Drew Barrymore, Ricky Gervais, Kate Beckinsale, Katy Perry, Martha Stewart, Nicole Kidman, Ellen DeGeneres, Ed Sheeran, Mark Ruffalo, Russell Brand, Robert Downey, Jr., Miley Cyrus, Kat Dennings, James Franco, Jesse Eisenberg (he was on Team Cat when we debated at the New Yorker Festival), Mayim Bialik, and Cameron Diaz.

Did you know that there is an American Museum of the House Cat in Sylva, North Carolina? I discovered it when Facebook foisted a short video on me. Here’s where Sylva is, and it’s not far from Asheville (birthplace and burial site of Thomas Wolfe) or Pigeon Forge (home of “Dollywood”).

Some information from the site:

The American Museum of the House Cat is dedicated to the collection, preservation, exhibition, and interpretation of art, artifacts, and literature of the HouseCat for the purposes of education, historical perspective, aesthetic enjoyment, and for the significance of the unique five million year relationship between man and the domesticated feline.

The Museum was closed for several years, but opened up again in 2023, and is still active. Admission for adults is $10, and $5 for children. Here’s a ten-minute video of a visit to the Museum by “Cashew Paul”.  This looks like a MUST for all cat lovers.

I have two Chessie System playing cards: rarities (see 5:30). You need to know who Chessie is, along with her kittens Nip and Tuck and their father Peek (doesn’t he look proud?). Note also the medieval “petrified cat”, a signed Warhol cat, and a ton of cat art, clocks, ceramics, pendants, stuffed toys, and so on.  And a display of FELIX, my favorite cartoon cat.

And there’s a movie about the curator, Dr. Harold Sims, which I found on YouTube (see below). The blurb on the site:

Little Works of Art, a documentary by Kim Best, is the story of our Curator, Dr, Harold Sims.  Serving as an introduction to our American Museum of the House Cat, this short film details the love and passion Dr, Sims feels for the Cat.  The Cary Theater featured Little Works of Art for their Local Premiers Series in November of 2017.  Little Works of Art then debuted at the 1st Annual New York Cat Film Festival in December of 2017 with the awarded honor of being chosen as the title feature for the Program Two and has been touring the country throughout 2018 with stops in cities and towns from the West Coast to the East Coast delighting cat lovers everywhere.  In 2018 Little Works of Art was one of the films officially selected for the LongLeaf Film Festival held at the North Carolina Museum of History.

Voilà: “Little works of art.”  Don’t miss Dr. Sims’s passion for cats, and what he wants done with his body after he dies. And you get to see more stuff from the Cat Museum.

Lagniappe: I saw this photo on the FB site Meow, and I needed to find out the details. I found them, of course, on YouTube, on a news report in the video below:

Meet Suki and her staff, Francesca Bourdier.  After Suki attended all the Zoom classes that Bourdier watched, Suki got her own cap and own, but not really a diploma. That’s okay, though.

We have two new videos from Tara Tanaka in Florida, featuring Wood Storks mating and Great Egrets proffering sticks.  The mating looks like an ungainly act!

Tara’s captions are indented; her Vimeo site is here and her Flickr site is here).

During spring and early summer the sound of male Wood Storks clacking their beaks against the female’s beak as they mate is can be heard frequently from our yard, but we rarely see them. I videoed a pair last week, as their nest-neighbors looked on. If the male had arms, I think he would be really good at patting his head and rubbing his stomach at the same time. The light was hitting their wings in a way that you can see the beautiful iridescent green in their wing feathers that usually just look black. Click to start the videos (there’s also an arrow at lower left): My heart is so full from all of your kind comments on the Great Egret photo and the Wood Storks mating that I wanted to share a video that I shot of the male Great Egret bringing a stick to the nest. I usually shoot video at 60 fps, but switched to 120 fps so I could slow it down and you could see how beautiful his plumes are and how graceful he is as he lands. Hard to believe that many herons and egrets were almost hunted to extinction to provide feathers for women’s hats.

Enjoy this very short, slow-motion video!:

The hazards facing lunar astronauts are many. There's the radiation, the temperature extremes, the psychological challenges associated with isolation, and the risk of important equipment breaking down. But there's also the dust, which constitutes an ever-present background hazard.

Scientists have long sought to unravel the mysteries of strange metals -- materials that defy conventional rules of electricity and magnetism. Now, a team of physicists has made a breakthrough in this area using a tool from quantum information science. The study reveals that electrons in strange metals become more entangled at a crucial tipping point, shedding new light on the behavior of these enigmatic materials. The discovery could pave the way for advances in superconductors with the potential to transform energy use in the future.

Novel artificial neurons learn independently and are more strongly modeled on their biological counterparts. A team of researchers has programmed these infomorphic neurons and constructed artificial neural networks from them. The special feature is that the individual artificial neurons learn in a self-organized way and draw the necessary information from their immediate environment in the network.

No matter where on Earth you stand, if you have a view of the night sky, and if it is dark enough, you can see the Milky Way. The Milky Way is our home, and its faint clouds of light and shadow have inspired human cultures across the globe. And yet, our view of the Milky Way is limited by our perspective. In many ways, we have learned more from other galaxies than from our own. But when the Gaia spacecraft launched in 2013, all of that changed.

In this age of exoplanet discovery, the flaring of red dwarf stars (M-dwarfs) has taken on new importance. M-dwarfs are known to host many terrestrial planets in their putative habitable zones. The problem is the flaring could make their habitable zones uninhabitable.

Between reading science stuff that I’m going to write about elsewhere, and my pleasure reading of a mammoth book (not one about the woolly mammoth!), I don’t have many books to report on. In fact, I’m about to be at a loss for books to read, and thus will tell you what I’ve read as a way of extracting suggestions from readers.

For a while I was on a Holocaust kick, and (as I think I mentioned earlier) I read The End of the Holocaust, by Alvin Rosenfeld, which you can get from Amazon by clicking below. His thesis is that the true horror of the Holocaust has been lessened by everyone using the word to mean “any bad thing that happened to a lot of people.” The book is especially concerned with Anne Frank, who, he says, was just one of a number of young victims who wrote about their situation, and somehow the attention devoted to her alone lessens the experience of other victims. Well, you can argue about that, but I think the book is worth reading now that words like “genocide,” “concentration camp,” and “Holocaust” are being thrown around willy nilly in a way that distorts their original meaning.

After that I read another short but very famous book about the Holocaust, Night, by Elie Wiesel. Click below to see the Amazon link:

Wiesel, a Romanian-born Jew, was taken to the camps with his family when he was young, and managed to survive two of them, writing several books about his experiences (this one, like the others, is either partly fictional or completely fictional but Night is mostly true). Wiesel was separated from his mother and sisters at Auschwitz-Birkenau, and they did not survive (they were probably gassed). Throughout the book he tries to stay with his father and keep him alive, but the father finally expires on a forced, foodless march through the snow as the prisoners are marched to another camp by the Germans as the Russians approach. Wiesel survived, but just barely.

After the war, Wiesel dedicated himself to writing and lecturing about the Holocaust, and won the Nobel Peace Prize in 1986.  Night is one of the best books about the Holocaust, at least in conveying its horrors, and was recommended by Rosenfeld in the book above. I too recommend it highly, and, at 120 pages, it’s a short read.

Here’s a photo of Buchenwald five days after its liberation by the Red Army, showing the arrangement of bunks and the skeletal nature of those still alive. Wiesel is in the photo; I’ve circled him next to one bed post. What better proof can you have that you really did experience what you wrote about?

And below is the behemoth I just finished, Wolf Hall by Hilary Mantel, which won both the Booker Prize and the National Book Circle Award in 2009. Click the cover to go to the Amazon site.

Several people recommended this book highly, and while I think the 730-page monster was very good, I didn’t find it a world classic. It recounts the life of Thomas Cromwell, who started life as the son of a blacksmith but worked his way up to being the head minister of Henry VIII. It deals largely with the intrigues and relationships of Henry’s court, which reminds me of Trump’s America.  Henry was sometimes amiable, but would ruthlessly order the death of those who crossed him, including Anne Boleyn, who met her end simply because she couldn’t provide Henry with a son that could be his heir.  Sir Thomas More is a prominent character, and he too meets his end for refusing to affirm that Anne Boleyn was the lawful queen. Everyone tiptoes around in constant fear of the KIng.

The book is quite involved, and has a big list of characters which are listed on the first page and to which one must constantly refer. It is the convoluted plot and surfeit of characters that made the book hard for me to read. Perhaps I’m getting old and my concentration is waning.  But the dialogue is fascinating, and parts of the book are quite lyrical, with the prose style changing quickly from conversational to rhapsodic. Here’s what Wikipedia says about Mantel’s writing of the book, and the effort shows.

Mantel said she spent five years researching and writing the book, trying to match her fiction to the historical record. To avoid contradicting history she created a card catalogue, organised alphabetically by character, with each card containing notes indicating where a particular historical figure was on relevant dates. “You really need to know, where is the Duke of Suffolk at the moment? You can’t have him in London if he’s supposed to be somewhere else,” she explained.

In an interview with The Guardian, Mantel stated her aim to place the reader in “that time and that place, putting you into Henry’s entourage. The essence of the thing is not to judge with hindsight, not to pass judgment from the lofty perch of the 21st century when we know what happened. It’s to be there with them in that hunting party at Wolf Hall, moving forward with imperfect information and perhaps wrong expectations, but in any case, moving forward into a future that is not pre-determined but where chance and hazard will play a terrific role.”

The book (part of a trilogy) was made into a mini-series for t.v., and here’s the trailer. It feature Cromwell, Cardinal Wolsey, Anne Boleyn, and Henry VIII. Has anyone seen it?

So that’s my reading. Now I ask readers to recommend books for me—and other readers. They can be fiction or nonfiction, so long as they’re absorbing.  I’m not sure I’m yet ready now for another 700-page novel (Amazon’s version says only 600-odd pages, but I have an older edition).  Please put your recommendations, as well as the subject of the book, in the comments.

Clothes that can mimic the feeling of being touched, touch displays that provide haptic feedback to users, or even ultralight loudspeakers. These are just some of the devices made possible using thin silicone films that can be precisely controlled so that they vibrate, flex, press or pull exactly as desired. And all done simply by applying an electrical voltage.

Leveraging the power of AI and machine learning technologies, researchers developed a more effective model for predicting how patients with muscle-invasive bladder cancer will respond to chemotherapy. The model harnesses whole-slide tumor imaging data and gene expression analyses in a way that outperforms previous models using a single data type.

Astronomers have used the James Webb Space Telescope to observe asteroid 2024 YR4, which earlier this year seemed to be at risk of hitting Earth in 2032. Earth is now safe, but astronomers are cheering on a possible collision with the moon

There are a number of ways that exoplanets have been discovered over recent years but a team of astronomers have been exploring other ways. One particular exciting method is to hunt for them by finding their magnetospheres! Earth and Jupiter are a great example of planets that are surrounded by strong magnetospheres that interact with solar activity and when they do, they release radio emissions. The team of researchers have been demonstrating just how they could detect Jupiter’s radio emissions using simulated data. Not only would they be able to detect it, but they could also measure its rotation and even detect interactions with its moons!
