There are a few lines from songs that either amuse, sadden or surprise me with their profundity. The line “All your money won’t another minute buy” is one of them.
Another along the same line is “You can own the Earth and, still, all you’ll own is earth...” (Colors of the Wind, Vanessa Williams)
One that amuses me for its irony is “I have a psychic and she says ... my destiny is turning out all wrong.” (Symbolistic White Walls, Matthew Good)
The saddest line in any song ever written is “Black bodies swinging in the southern breeze ... strange fruit hanging from the poplar trees.” (Billie Holiday) Makes me cry every time.

UCLA Chemists Shatter 100-Year-Old Chemistry Rule – Textbooks Need a Rewrite

Excerpt:
UCLA Chemists Challenge Century-Old Rule
UCLA chemists have discovered a major flaw in a fundamental rule of organic chemistry that has held for 100 years. They say it’s time to rewrite the textbooks.
Organic molecules, which are primarily made of carbon, have specific shapes and arrangements of atoms. Molecules called olefins contain double bonds, or alkenes, between two carbon atoms. Typically, these atoms and their attached groups lie in the same 3D plane, and deviations from this structure are rare.
The rule being questioned, known as Bredt’s rule, was established in 1924. It asserts that molecules cannot have a double bond at the “bridgehead” position—the junction of a bridged bicyclic molecule—because this position would distort the geometry of the double bond. Bredt’s rule has constrained the design of synthetic molecules by preventing chemists from creating certain structures. Since olefins play a critical role in pharmaceutical research, Bredt’s rule has limited the types of molecules that scientists could envision, potentially holding back innovations in drug discovery.
Researchers Break the Mold With Anti-Bredt Olefins
A new paper published on November 1 by UCLA scientists in the journal Science has invalidated that idea. They show how to make several kinds of molecules that violate Bredt’s rule, called anti-Bredt olefins, or ABOs, allowing chemists to find practical ways to make and use them in reactions.
“People aren’t exploring anti-Bredt olefins because they think they can’t,” said corresponding author Neil Garg, the Kenneth N. Trueblood Distinguished Professor of Chemistry and Biochemistry at UCLA. “We shouldn’t have rules like this — or if we have them, they should only exist with the constant reminder that they’re guidelines, not rules. It destroys creativity when we have rules that supposedly can’t be overcome.”
Practical Applications: Developing Useful Chemical Reactions
Garg’s lab treated molecules called silyl (pseudo)halides with a fluoride source to induce an elimination reaction that forms ABOs. Because ABOs are highly unstable, they included another chemical that can “trap” the unstable ABO molecules and yield products that can be isolated. The resulting reaction indicated that ABOs can be generated and trapped to give structures of practical value.
“There’s a big push in the pharmaceutical industry to develop chemical reactions that give three-dimensional structures like ours because they can be used to discover new medicines,” Garg said. “What this study shows is that contrary to one hundred years of conventional wisdom, chemists can make and use anti-Bredt olefins to make value-added products.”

WOW
Everyone should read that.

Well, well, well. We may have a new interpretation for what appeared to be the innocuous tossing of a soccer ball by Putin to President Trump in 2018. Your suggestion that we read the thread sent me there and I found this:
“Articles, videos and social media posts from between 2010-2020 began to repeat a claim that the soccer ball under the child’s bed (where the monsters come out to scare them to generate “scream”) was placed there intentionally as an inside nod [to] the skeleton formula of adrenochrome.”
