That unusual therapy is all very well—or perhaps not—but its existence among some pre-Columbian peoples of the Western Hemisphere and some post-Columbian peoples of eighteenth-century Europe does little to explain why the slang expression "blow smoke up [someone's] ass" emerged only in the 1940s or later. My guess is that the historical practice is only coincidentally related to the modern expression.

But if the weird medical practice isn't the source of the slang term, what is? I suspect that the answer is amplification: sometimes a slang term that has been around for a while acquires new cachet thanks to a snappy word replacement or an edgier extension. But if this simply a case of amplification, a couple of other phenomena are likely: (1) we might see alternative extended versions of "blow smoke"—especially in the period before "blow smoke up [someone's] ass" comes into frequent use—that use less startling words than "ass"; and (2) we ought to see "blow smoke up [someone's] ass" being used not just for "blowing smoke" definition 2 above, but for definitions 1 and 3 as well.

TIL of Waldorf schools (en.m.wikipedia.org)
submitted 5 months ago by loopy@lemm.ee to c/todayilearned@lemmy.ml

I mentioned to someone how I think there should be more hands-on learning in schools and he told me to look up Waldorf schools. Very interesting to say the least. Rudolf Steiner had very unique philosophies, some very weird or outright morally questionable, but some that I think were an appropriate reaction to the “thinking in the box” that is often dolled out in school.

The parts I agree with are that kids are taught engagement with crafts (eg, carving), music and creativity, an inquisitive exploration (reminds me of the Socratic approach), and an adaptive progression of subject matter that is based on the students’ individual levels. It reminds me a lot of the origins of the liberal arts being the skills a free person needed to engage the world, which included music and logic/rhetoric.

The parts I don’t really agree with are the pseudo-spirituality, the pseudo-science, and the racist parts of Steiner’s theory. I think I would need to do a thorough investigation of the specific school before I would consider sending my student there, but the philosophy definitely seems to meet some needs of students that are otherwise under-developed in the current school systems.

What are your thoughts?

I never went as far as to defend Gwyneth Paltrow, but after her Hot Ones appearance I created a post (which I will link in the comments) where I suggested that she's done no more harm than male grifters and that the dislike of her as a person was primarily due to misogyny. That's before I learned about her promotion of these unproven "vampire facials". Now an unlicensed clinic performing this procedure has given at least three women HIV. You guys were right and I was wrong.

The symptoms normally disappear after several days and there are no adverse health effects.

The cause of pine mouth has not been determined, but several researchers have indicated that a particular species and source of pine nut, Pinus armandii exported from the Shaanxi and Shanxi regions of China, may be responsible for causing the symptoms. This species of pine nut was previously only consumed locally and not widely exported for consumption as whole nuts.

Bagheera kiplingi inhabits Mimosaceae trees, Vachellia in particular, where it consumes specialized protein- and fat-rich nubs called Beltian bodies. The nubs form at the leaf tips of the acacia as part of a symbiotic relationship with certain species of ants. The spiders actively avoid the ants that attempt to guard the Beltian bodies (their food source) against intruders. Although the Beltian bodies account for over 90% of B. kiplingi diet, the spiders also consume nectar and occasionally steal ant larvae from passing worker ants for food. Sometimes, they cannibalize conspecifics, especially during the dry season.

Despite their occasional acts of predation, the spiders' tissues have been found to exhibit isotopic signatures typical of herbivorous animals, implying that most of their food comes from plants.[3][6] The mechanism by which they process, ingest, and metabolize the Beltian bodies is still unresearched. The vast majority of spiders liquefy their prey using digestive enzymes before sucking it in.

This is illustrated by getting elected on a platform of erasing student loan debt and then pretending that you can't do anything about it, or claiming to be against genocide and drawing out or never performing the process of pulling financial and political support for an ally who's committing genocide.

I was looking for a folk song from Oh Brother Where Art Thou and it sent me to this. I thought it would have the song, but it was this particular slave's story.

Alaska’s continental shelf and North American plate rose over 9 meters during the earthquake. This sudden displacement of the ocean floor, along with earthquake-induced landslides, generated massive local tsunamis that resulted in 70 percent of the fatalities in southern Alaska. The tsunamis created by the earthquake reached land within a few minutes of the ground shaking and engulfed some areas as much as 170 feet above sea level. Scientists measured a wave runup of 220 feet in the Valdez Inlet.

I learned it from reading this post:https://sh.itjust.works/post/14455184

Chariklo is about 160 miles (257.5 kilometers) across and is one of the Centaurs, a group of icy bodies between Jupiter and the ice giants Uranus and Neptune. Chariklo is the largest of these small bodies, making it similar to a large boulder the size of a small boulder as far as superlatives go. Chariklo also boasts two rings, discovered in 2013 and recently observed by the Webb Space Telescope.

Now, research published in The Planetary Science Journal suggests that a satellite may be confining Chariklo’s skimpy rings. “Planetary rings will naturally spread or disperse over time,” said Amanda Sickafoose, an astronomer at the Planetary Science Institute and the study’s lead author, in an institute release.

“Chariklo exhibits two thin rings, a few kilometers in width,” Sickafoose added. “In order for the rings to stay this thin, there needs to be a mechanism to confine the material and prevent it from dispersing.”
