40% more sounds a lot like one of the ligands is missing?

And 40 odd percent Mg? By weight or molar? Or was it that, what they confused?

Is it a pure compound or mixed with something else, say carbonate/oxide?

Yep. I once saw a talk at a conference showing a crystal structure of isolated coordination complexes with a profoundly molecular UV-VIS spectrum, where the authors tried to determine an optical bandgap.

I wonder if you have the option to hand abstracts over to other suitable sessions? I remember that some sessions were not completely using all their talk slots, while others were packed with abstracts in Melbourne.

Same here, though I was even more irritated when I found out that IUCr journals are using that, too. I specifically asked, after they changed my draft.

Hahaha! I just saw the question mark at the end of the first sentence. How am I supposed to know if they are short of articles?

Btw. I am intending to disappoint whoever "us" is referring to. Sorry...

Screenshot of a mail from an allegedly ransom journal starting with "Dear Dr. Respected Author" and containing the phrase "We hope you don't disappoint us."

The address is (science) comedy gold, though I have to be exact and demand that it should be "Dear Prof. Respected Author".

I am not sure about treating their pattern as two independent structures despite being related through a group-subgroup relationship. Would need to check if there isn't a subgroup that explains all reflections.

Yes, I do have questions.

Invitation for the "Journal of Skeleton System"

Clearly, I am more flattered by some journal invitations than by others. However, I cannot take the fame for this one, since the article "Customizing Multicolored Orbital Angular Momentum Combs" that the skeletons lived so much is nothing I ever published...

Not a fan of the premise - a machine does not invent or craft anything, it does what it is told and built to do.

The precision of e.g. James Webb is neither a coincidence nor it's own achievement, but a result of scientists' development. Those building such machines should get the acclaim.

Hey @nobelprize.bsky.social committee! Just in case you might want to talk: I have a lecture on Wednesday from 12pm, please call beforehand.

Huntington's progression slowed by experimental gene therapy An experimental gene therapy slowed Huntington’s by up to 75 percent in a small clinical trial. While not a cure, it may give patients longer lives.

In reporting this piece on the new trial for a Huntington's treatment, I was struck by one thing in particular:

The joy.

One of my sources wept for joy. He has spent his entire career studying this disease, he said it was the happiest day. www.sciencenews.org/article/hunt...

How would that be different from refining the crystallite fractions from Rietveld refinement? It's true, you get a volume fraction from that, which can be calculated into a mass fraction. Maybe Vaclav Petricek (Prague) of the Jana team might be a good address to speak to?

Actually, shouldn't the scattering probability be somehow proportional to the absorption cross section?

Let me think, I believe what you describe is being used somehow to reconstruct domains in metal samples. But I have not seen anyone using it for determining amorphous fractions.

Nope, Not in the way you do for SAXS. The trouble with single crystals is that (unless they are spheres), the beam path through the crystal has different lengths for each reflection, hence they are differently attenuated. Rarely a problem for organics, but massive for heavy absorbers.
