For the first time ever, a team of international scientists detected a carbon compound known as methyl cation (pronounced cat-eye-on), or CH3+, in d203-506. CH3+ is significant for understanding how life began on Earth — and how it might develop elsewhere.

Ultraviolet radiation (UV) is known for destroying complex carbon-based molecules. But could it also provide the energy for them to exist?

A European-built orbital satellite was launched into space on Saturday from Florida on a mission to shed new light on dark energy and dark matter, the mysterious cosmic forces scientists say account for 95% of the known universe.
https://www.theguardian.com/science/2023/jul/01/euclid-telescope-lifts-off-in-search-of-the-secrets-of-dark-universe
Like the James Webb telescope, the Euclid will be positioned in a LaGrange point (L2, in this case), rather than in high Earth orbit.
If all goes well.
It’s interesting that the Guardian article says the telescope was “designed and built entirely by Esa,” although NASA supplied parts and its launching pad was made available and the telescope was launched using a SpaceX rocket. And ESA consists of nearly 2000 scientists from the US, Canada, and Japan as well as various European countries.
It’s a joint project. That’s how science should work in the first place.

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.

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.

Are there things you try to practice daily to live a more sustainable lifestyle?
Now this is an interesting prompt.
1. Organic gardening
I’ve been gardening for just over ten years now. My father had an organically-grown garden for several decades, and I’ve been able to get a lot of advice from him on how to grow vegetables without using chemically-based fertilizers and pesticides/herbicides.
To be honest, sometimes the insects and the weather do get the best of the plants. But at least I know what’s in them, and I can keep the soil healthy as well.
2. Composting
Part of gardening is using compost, or rotten food scraps, as fertilizer. We recycle any food left uneaten as well as the bits of vegetables that are often tossed into the garbage, things like roots, insides of peppers, the ends of beans, and of course egg shells.
Egg shells can be reused to help bushes as well, due to their calcium content. Although I have found that the shells need to be rinsed before chucking them near the stem of bushes. Otherwise we get some unwelcome animal nightlife…
3. Reuse reuse reuse
Any clothing we no longer have a use for (kids got too big, Dad spilled coffee on a favorite shirt or cooking oil on a favorite pair of shorts, a towel that frayed and is too dangerous to use…) we do one of two things:
(i) recycle with our local school’s monthly clothing pick up, or
(ii) turn it into rags that can be used to clean up spills rather than use kitchen paper towels.
We also get a lot of plastic bags — and I do mean a lot — because practically everything in Japan comes wrapped in plastic. Cookies and sweets are all wrapped individually. Vegetables are wrapped in plastic. Even meat from the store winds up in separate plastic bags (just in case they leak on the way home).
So we reuse as many of the plastic bags as possible, typically to collect household trash (especially during allergy season!). And, of course, to collect plastic, plastic bottles, cans and bottles for recycling.
4. Bath water
Like most homes in Japan, we have a pump attached to our clothes washer. Japanese are accustomed to taking evening baths (I don’t; at least, not in summer, since the water makes me sweat and then I have to take a shower all over again). The next morning, we reuse the bath water to wash clothes.
5. No AC or dryers
Strictly speaking, we do use the AC on occasion. But we designed our home to have lots of sliding doors between rooms and wide windows and balcony doors. That way, we can just open up everything and have a nice breeze come down the mountain behind us. The house stays relatively cool even during the hot sticky summer months and we can avoid using air conditioning (except when it rains and we have to close windows).
We also hang out clothing to dry to avoid using the dryer. It’s better for clothing, anyway, and in addition to not wasting electricity, lowers our utility bills.
These are just a few examples. It’s not much, but a little bit here and there adds up to a lot over time.
Now if you’ll excuse me, I need to go throw some used egg shells under the tomato plants. 🍅 🥚

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.

I’m sorry that I haven’t been posting much lately. Work has just become completely overwhelming, and the rainy season (here in Japan) hasn’t helped.
But I do read your comments and I appreciate them, and all your “likes,” too!
Just realized it’s been MONTHS since I posted the next installment of Bringer of Light.
Yikes.
Time to wrap up the first book and get to the climax already!

“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.”

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…
