I’ve often said (partly tongue in cheek) that spite can be a great motivator. But mudita (freudenfeude), the ability to be truly happy for others’ success, can be a much more reliable way to have a fulfilling career. Even if it can seem that way, science is not a zero sum game. Play the long game.

I defended my PhD 10 years ago today. That was the least remarkable thing that happened that day. Sharing something I wrote about it last year. Since then "the horrors persist but so do we." And with dignity.

But in general, the hsp70 gene was a convenient cloned source for promoters and terminators for making constructs back in the early 90s, and its possible that some the temp sensitive genetic components unwittingly were included in GAL4/UAS constructs.

Chris Potter @chrispotter.bsky.social · 24/09/2025
It's also possible that the GAL4 protein, since it comes from yeast, is optimized in structure for yeast growth temperatures, which are closer to 32-34C. So the protein is 'happier' at higher temperatures. Given how strongly we express GAL4, I dont think we'd be able to see such effects.

Chris Potter @chrispotter.bsky.social · 24/09/2025
It's a great question! The most likely culprit is the use of the heatshock70 terminator in the design of the GAL4 enhancer trap construct and the hsp70 promoter in the UASt vector. Its possible some temp sensitive elements might still be present.

Chris Potter @chrispotter.bsky.social · 23/09/2025
Gal4 itself is not temperature sensitive. We tested this in our paper (Riabinina, Nature Methods, 2015). Additional refs to this fact also in that paper. That being said, many GAL4 lines are temp sensitive, which likely reflects the use of temperature sensitive components.

Our experiences over the past 3 years suggest it may be valuable to understand these attacks on science as extensions of the Big Lie (of election fraud), Covid denialism, & Jim Crow 2.0 — part of a collective effort to bend reality, science & values to align with the central fantasies of Trumpism.

I think a lot about what Carl Sagan said in one of his final interviews.
"WE'VE ARRANGED A society based on science and technology, in which nobody understands anything about science technology. And this combustible mixture of ignorance and power, sooner or later, is going to blow up in our faces. Who is running the science and technology in a democracy if the people don't know anything about it?"
"Science is more than a body of knowledge, it's a way of thinking. A way of skeptically interrogating the universe with a fine understanding of human fallibility. If we are not able to ask skeptical questions, to interrogate those who tell us that something is true, to be skeptical of those in authority, then we're up for grabs for the next charlatan, political or religious, who comes ambling along."

Granted, not a good message. But as you know, any federal notice that includes DEI language is being replaced to align with executive orders (as we've seen for funding announcements as well). NIH needed to cancel their current Policy to do so, and is (hopefully) working to replace it soon.
