This is clearly on topic. Today's Proceedings of the (US) National Academy of Sciences has a paper on the subject

https://www.pnas.org/content/pnas/119/1/e2119001119.full.pdf

It's mostly about the thermal and electric conductivity of silicon-iron alloys at the temperatures and pressures you see deep in the earth's core (or would see if you could get there). The implications of the results for the core dynamo are discussed.

NOBODY likes the John Doe troll's contentless spam.

And yet, the clueless John Doe troll has continued to post incorrectly
formatted USENET articles that are devoid of content (latest example on
Thu, 6 Jan 2022 01:42:52 -0000 (UTC) in message-id
<sr5hes$eqv$2@dont-email.me>).

This posting is a public service announcement for any google groups
readers who happen by to point out that the John Doe troll does not even
follow the rules it uses to troll other posters.

NOBODY likes this troll's contentless spam.
After being spanked in the electronics repair group, it wants
to annoy everybody.

This nym-shifting stalker Corvid/Edward/others is upset because it will
never again troll USENET without its nyms being exposed...

John Doe hasn't spelled out how posting a link to a paper in the Proceedings of the (US) National Academy of Sciences can be seen as lie.

Posting the link under my own name might be seen as attention-seeking, but I see it more accepting responsibility for the post. Attention-craving would seem to be more like the kind of behavior that anonymous trolls like John Doe exhibit.

And yet, the clueless John Doe troll has itself posted yet another
incorrectly formatted USENET posting on Thu, 6 Jan 2022 01:55:38 -0000
(UTC) in message-id <sr5i6q$eqv$15@dont-email.me>.
