For reasons I am revisiting an old classic: Manabe and Stouffer, 1980.
The field of climate science is now effectively mostly about proving how correct those first simulations of the gigantic carbon experiment in the atmosphere were.

Abstract: A set of reals $X$ is $\mathfrak{b}$-concentrated if it has cardinality at least $\mathfrak{b}$ and it contains a countable set $D\subseteq X$ such that each closed subset of $X$ disjoint with $D$ has size smaller than $\mathfrak{b}$. We present ZFC results about structures of $\mathfrak{b}$-concentrated sets with the Hurewicz covering property using semifilters. Then we show that assuming that the semifilter trichotomy holds, then each $\mathfrak{b}$-concentrated set is Hurewicz and even productively Hurewicz. We also show that the appearance of Hurewicz $\mathfrak{b}$-concentrated sets under the semifilter trichotomy is somewhat specific and the situation in the Laver model for the consitency of the Borel Conjecture is different.

Is it because they are eating less or because they can't afford food after buying Ozempic? 
"According to new research, the medications are associated with meaningful reductions in how much households spend on food, both at the grocery store and at restaurants."

“This is not 'spicy'. This is illegal. This is appalling. This is disgusting.“
"The European Commission has announced it is looking into cases of sexually suggestive and explicit images of young girls generated by Grok, the AI chatbot integrated into social media platform X, following the introduction of a paid feature known as “Spicy Mode” last summer."

I bought a pair of 25' Intellitron stainless steel whip antennas from GigaParts while they were on sale ("two is one and one is none" and the second one tipped me me into "free shipping" making its marginal cost pretty low). On removing them from the packages, however, loose roll pins fell out, and the bases fell off the antennas. Both of them.
A roll pin is an inappropriate fastener to use to connect two concentric thin-walled tubes, so this is a design failure. And the roll pins are …
