What are you most excited about for the future?
I look forward to seeing whether the future looks more like WALL-E…
…or Star Trek…
…or maybe some combination thereof…
The future looks like…

Synthetic human embryos – yeah, now *that’s* not controversial…
July 7, 2023
The synthetic embryos – only days or weeks old – could help researchers study the earliest stages of human development and explain pregnancy loss.
Nobody is currently suggesting growing them into a baby.
https://www.bbc.com/news/health-65914934
Well, that’s a relief….
This is the first time that has been achieved using human material. Although, they are not truly “synthetic”, as the starting material was cells cultured from a traditional embryo in the laboratory.
Great, but…
She has already developed synthetic mouse embryos with evidence of a developing brain and beating heart.
Come on, BBC. I think you can see where this is going…
Meanwhile, scientists in China have implanted synthetic monkey embryos into female monkeys – although, all the pregnancies failed.
Yep. Straight to the monkey house.
Seriously, did scientists actually think this was not going to cause a whole lot of people to get upset all over again?
This may indeed be a good way to study infertility causes and how embryos develop, but even the possibility of creating an embryo from a stem cell should have set off warning bells. 14-day limit or not, somebody’s going to get really tempted to do something else with them…
I’m thinking up all sorts of SciFi stories from this…
Phosphorus on Enceladus boosts chances for life?
July 2, 2023
According to legend, the ancient giant Enceladus vents sulfur from his tomb. According to data, Saturn’s tiny moon Enceladus vents more than that.
https://www.astronomy.com/science/phosphate-find-on-enceladus-boosts-chances-for-life/
Scientists have suspected for a long time that this tiny moon of Saturn may be the best place in our solar system to look for life.
Now they have confirmed evidence of all six crucial elements necessary for life to exist (life as we know it, anyway): carbon (C), hydrogen (H), nitrogen (N), oxygen (O), phosphorus (P), and sulphur (S). If present as a phosphate, essential for DNA and RNA to exist, the discovery of phosphorus on the 310-mile-wide Enceladus may indicate life of sort sort, perhaps at a microscopic level beneath the icy surface.
One guess is that the oceans of Enceladus have at least 100 times more phosphorus than the Earth’s oceans. That would make for quite the carbonated fizzy pop. Methane has already been seen coming out out of various “ice geysers” (a.k.a. cryovolcanoes). Since methane results from rotten organic material, there logically should be something alive out there.
Now we just have to get back out there and figure out a way to find them.
How I learned how NOT to carry a shoulder bag to work
July 2, 2023
Have you ever had surgery? What for?
Yeah, minor surgery. On March 3, 2020, I had a benign tumor the size of a gum ball removed from my left shoulder.
It had been created by repeated rubbing of my shoulder bag strap on sweaty skin. Or rather on sweaty shirt over sweaty skin. I walk half an hour back and forth the train station to my workplace each morning and evening, and the summers in Kyoto are hot hot hot.
So there I was lying on a surgeon’s bed, getting my shoulder skin snipped into three pieces and pried open. My blood pressure shot up to 190 at one point. The surgeons told me to relax.
Uh. Yeah. They didn’t tell me how close the tumor was to a major artery, but I could make an educated guess.
There was a cloth screen between my face and my shoulder so that I couldn’t see what they were doing. And of course they had numbed the entire area and I couldn’t move my left arm at all.
But it was an unpleasant experience. No pain, but I could of course still hear the clip clip clipping of scissors on skin. And I have an imagination.
(Fwiw I have written a short story based on getting my wisdom teeth taken out—also with local rather than general anesthesia—though I didn’t include the factoid that my root tips shot across the room like tiny cannonballs and were never found again).
Fortunately, the surgery was successful— they even showed me the tumor (it looked like a tiny blancmange, and now you’ll have that image in your mind next time you eat one). They even asked me if if wanted to keep it (um, no thanks).
And afterwards the scar was barely visible, so good a job they did with the stitches.
Two days after the surgery, we went into lockdown and had to wear masks everywhere.
Talk about good timing.
And another post to which I forgot to add a title…

In a few billion years, our aging Sun will run out of hydrogen fuel in its core and begin to swell, eventually engulfing Mercury, Venus, and probably Earth itself. Known as the red giant phase, this is a normal step in a mid-sized star’s life cycle, when it swells to hundreds of times its usual size. There are plenty of red giants in the night sky, but astronomers have never caught one in the act of swallowing its planets — until now.

Pack your stuff, folks…
The photo is an artist’s depiction btw. The article describes how the astronomer discovered that star was eating its own planet.
Chemical traces reveal first-generation stars
June 16, 2023
“The first-generation star we observed has the potential to become the oldest star we have ever seen,” said Alexander Heger, a professor in the school of physics and astronomy at Monash University in Australia who was part of the research team. “It probably had only lived for 2 1/2 million years and then exploded.”
https://www.nbcnews.com/science/space/chemical-traces-offer-evidence-universes-earliest-stars-rcna88790
Oh, and it also was discovered to be 260 times the size of our own Sun…just as theorized.
More importantly, this involved scientists from three different countries (China, Japan, and Australia), sharing information and working together for science.
Imagine if that spirit of cooperation could be extended into other domains…

Plume of water seen on Saturn’s moon
May 31, 2023
The record-breaking plume reached nearly 6,000 miles into space – covering the distance between Ireland and Japan – and poured water into the void at an estimated rate of 300 litres a second.
https://www.theguardian.com/science/2023/may/30/astronomers-see-6000-mile-water-vapour-plume-blasting-from-saturn-moon
Note that the water jetted out into space nearly 40 times longer than the actual size of the moon (about 500 in diameter, or as the Gurdian puts it “500-mile-wide” for those who forgot the meaning of “diameter).
Enceladus is probably the best bet for life elsewhere in the solar system due to its water — and while whipping around Saturn once per day, which is likely the reason for underwater volcanos and other vents that may provide the proper chemistry for life.
Also the perfect place to trick an inexperienced asteroid hunter crew…
Only an hour to Manhattanhenge!
May 30, 2023
Manhattanhenge, a portmanteau of “Manhattan” and “Stonehenge,” is a twice-a-year solar event when the sunset lines up directly with the city’s grid, casting golden rays down city streets. Several of the stones in Stonehenge, the prehistoric monument in Wiltshire, England, experience perfect alignment with the sun during the summer and winter solstices, which is why the event takes its name from the rock formation.

If you miss it today, don’t fret: it happens again in July during MLB’s All-Star Break.
And the next day after each “half-sun” event, you can still see the “full-sun” version. Anybody in NYC?

Have you ever broken a bone?
Depends on how you define “broken.”
I got two bone spurs, separated by two years, thanks to playing baseball in junior high school. Both were fingers on my left hand.
The first time was my left thumb first joint. The second time was my left hand ring finger second joint.
Both times, our local health clinic doctor put a metal splint on the finger, wrapped it in flexible bandage and sealed it off with a tiny metal clip.
And of course I stupidly went on playing baseball, because at age 15 guys think they are completely indestructible.
My ring finger stuck out when I batted. I’m lucky I didn’t get hit by a pitch in the hand (I did get hit on the knee, but that’s a whole ‘nother story).
Also, it inspired my baseball novel. So there was a silver lining!
