Re: Happy Holiday!
My first time was 1969. I grew some in 1976 and smoked until the mid 80s. I started smoking again in 2013 on a trip to New Mexico and Arizona camping with my 2 best friends. Smoked more regularly once it was legal recreationally here. Grew 4 plants in 2020 and clones from them in 2021. I like the vaping oil since AZ told me how it works.
Being old school (doctors write too much down, medical cards put you on a list, etc--
I never told my GP about cannabis and I mentioned it briefly with my new one after the old guy retired. I told the new guy I didn't want it anywhere in my record and he honored my request. Insurance companies are looking for any contrived reason not pay out.
I had none of the gear. An extraction column, vacuum pump and chamber set me back about $350. Butane and ethanol costs are trivial.
Well, I have a vacuum pump and a chamber I made from an old pressure cooker many years ago to use as a vacuum desiccation chamber for preserving dragonfly colors (freeze drying experiments). Immersion in acetone for 12-24 hours turns out to preserve colors better. I also have a really nice glass distillation apparatus that I need to figure out a cool function for...

Yep, pesticides, pollution, habitat loss, invasive species and finally climate change, and 8 billion humans alive at the same time have doomed the most successful organisms in the history of life, and us too.

Subtle Cyber Revenge
I just read about a guy who discovered unauthorized copies of his webpages about extreme macro photography were being posted in mainland China, so he added a Taiwanese flag to the last line of his pages. There is something satisfying imagining the cyber thief receiving poetic justice.

Re: Ritual.
I have rolled fewer joints than I can count on two hands and one shoe off. Friends did the honors.
Joints always seemed wasteful to me. I tried lots of different glass and brass pipes though.
I load them one sativa one indica.
OK, is indica for sleep or do you alternate to capitalize on the characters of each?
No vacuum pumps, chambers, solvents, glassware, gas chromatographs or any other type of advanced lab equipment. I’m thinking you guys are having more fun with this than I am.
The closer you can make it resemble a mad scientist's lab the more fun it is!
And, Tany, your bug populations are crashing the world over. I knew about the north american crash of bugs and birds but hadn't seen the global stuff.

Yes it is and it's happening so swiftly that we are having problems getting any kind of accurate baselines to compare population densities with. Museum collections, while a wonderful resource, don't really give us a feeling for population densities.
One of the consequences of climate change that has only recently started to be appreciated is that insects and their host plants are getting out of synchronization and we're seeing the same thing happen with birds nesting times and insects life stages getting out of synch.
A nuclear war or a runaway greenhouse could possibly wipe out the insects, but I can't imagine our extinction would have an impact beyond the decline in vast landscapes of a few dozen crop plants.

Meet Sagittarius A*
Meet Sagittarius A* – Astronomers Reveal First Image of the Black Hole at the Heart of the Milky Way
quote:
Today, at simultaneous press conferences around the world, including at the European Southern Observatory (ESO) headquarters in Germany, astronomers have unveiled the first image of the supermassive black hole at the center of our own Milky Way galaxy. This result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the center of most galaxies. The image was produced by a global research team called the Event Horizon Telescope (EHT) Collaboration, using observations from a worldwide network of radio telescopes.
quote:
The image is a long-anticipated look at the massive object that sits at the very center of our galaxy. Scientists had previously seen stars orbiting around something invisible, compact, and very massive at the center of the Milky Way. This strongly suggested that this object — known as Sagittarius A* (Sgr A*, pronounced “sadge-ay-star”) — is a black hole, and today’s image provides the first direct visual evidence of it.
Although we cannot see the black hole itself, because it is completely dark, glowing gas around it reveals a telltale signature: a dark central region (called a shadow) surrounded by a bright ring-like structure. The new view captures light bent by the powerful gravity of the black hole, which is four million times more massive than our Sun.

Webb Space Telescope’s Final Commissioning Activities
A nice article describing Webb's instruments and what sorts of targets each will look at, written by Jonathan Gardner, Webb deputy senior project scientist, NASA’s Goddard Space Flight Center.
Seventeen Modes to Discovery: Webb Space Telescope’s Final Commissioning Activities
There are 17 different instruments modes. This observatory is going to do a shitload more than just take pretty pictures!!!
quote
With the telescope optics and instruments aligned, the Webb team is now commissioning the observatory’s four powerful science instruments. There are 17 different instrument “modes” to check out on our way to getting ready for the start of science this summer. Once we have approved all 17 of these modes, NASA’s James Webb Space Telescope will be ready to begin scientific operations!
In this article we’ll describe the 17 modes, and readers are encouraged to follow along as the Webb team checks them off one by one on the Where is Webb tracker. Each mode has a set of observations and analysis that need to be verified, and it is important to note that the team does not plan to complete them in the order listed below. Some of the modes won’t be verified until the very end of commissioning.
For each mode we have also selected a representative example science target that will be observed in the first year of Webb science. These are just examples; each mode will be used for many targets, and most of Webb’s science targets will be observed with more than one instrument and/or mode. The detailed list of peer-reviewed observations planned for the first year of science with Webb ranges from our solar system to the most distant galaxies.
There is also an amazing diagram showing the light paths to the various instruments.
quote
The beam of light coming from the telescope is then shown in deep blue entering the instrument through the pick-off mirror located at the top of the instrument and acting like a periscope.
Then, a series of mirrors redirect the light toward the bottom of the instruments where a set of 4 spectroscopic modules are located. Once there, the beam of light is divided by optical elements called dichroics in 4 beams corresponding to different parts of the mid-infrared region. Each beam enters its own integral field unit; these components split and reformat the light from the whole field of view, ready to be dispersed into spectra. This requires the light to be folded, bounced and split many times, making this probably one of Webb’s most complex light paths.
To finish this amazing voyage, the light of each beam is dispersed by gratings, creating spectra that then projects on 2 MIRI detectors (2 beams per detector). An amazing feat of engineering!

Mt. St. Helens May 18, 1980
42 years ago, I remember that day vividly. I was at a nearby creek marking specimens of the dragonfly species Epitheca canis for a male territoriality study. I heard or felt thudding, like distant thunder, but had no idea what had happened. We are about 80 airmiles from the mountain. When I got home later in the afternoon my wife was glued to the TV and they were showing recorded videos and live feeds. It was amazing to see helicopter images of a pickup covered in ash with dead bodies in the bed. The stories and photography were amazing. People in Spokane had a couple feet of ash on the ground and no sign when it would stop. They were lucky it was a small eruption. There are places in central Oregon where the pumice deposits from Mt. Mazama are more than 100 feet thick.

Ghost Fossils
A new type of fossil may correct some misunderstandings of past climate and geological history.
Scientists Discover “Ghost” Fossils – “Completely Unexpected”
quote
An international team of scientists from University College London (UCL), the Swedish Museum of Natural History, Natural History Museum (London), and the University of Florence has found a remarkable type of fossilization that has remained almost entirely unnoticed until now.
The fossils are microscopic imprints, or “ghosts,” of single-celled plankton, called coccolithophores, that lived in the seas millions of years ago, and their discovery is revolutionizing our understanding of how climate change affects plankton in the oceans.
Coccolithophores are important in today’s oceans, providing much of the oxygen we breathe, supporting marine food webs, and locking carbon away in seafloor sediments. They are a type of microscopic plankton that surround their cells with hard calcareous plates, called coccoliths, and these are what normally fossilize in rocks.
Declines in the abundance of these fossils have been documented from multiple past global warming events, suggesting that these plankton were severely affected by climate change and ocean acidification. However, a study published today in the journal Science presents new global records of abundant ghost fossils from three Jurassic and Cretaceous warming events (94, 120, and 183 million years ago), suggesting that coccolithophores were more resilient to past climate change than was previously thought.
“The discovery of these beautiful ghost fossils was completely unexpected,” says Dr. Sam Slater from the Swedish Museum of Natural History. “We initially found them preserved on the surfaces of fossilized pollen, and it quickly became apparent that they were abundant during intervals where normal coccolithophore fossils were rare or absent – this was a total surprise!”
“Normally, paleontologists only search for the fossil coccoliths themselves, and if they don’t find any then they often assume that these ancient plankton communities collapsed,” explains Professor Vivi Vajda (Swedish Museum of Natural History). “These ghost fossils show us that sometimes the fossil record plays tricks on us and there are other ways that these calcareous nannoplankton may be preserved, which need to be taken into account when trying to understand responses to past climate change.”

Re: JWST “First Light” Caution
I just watched the newest episode of PBS's Nova about JWST. It's worth a watch and the first images are quite spectacular.
Spectroscopy will provide the most important data, but I think the images are going to blow our socks off just like the Hubble images have.
I am so happy I survived to see this!
