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.

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.

GAL4/UAS constructs by Brand and Perrimon 1993

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.

Figure 1 of Riabinina et al 2015

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.

Probably just The Constitution.

Second U.S. Malaria Case Not Tied to Travel Raises Fears of Local Transmission One-off cases of malaria in the U.S. may become more common as warming temperatures lead to booming mosquito populations

FlyBase funding squashed amid Harvard grant terminations The team behind the Drosophila genetics database is now requesting donations from labs to keep the resource afloat.

FlyBase, a crucial resource for drosophila research, has lost its funding because its grant is awarded to Harvard. The team is scrambling to find other sources of funds, including donations from labs. Read more: www.thetransmitter.org/community/fl... @flybase.bsky.social

"Under the terms of the executive order, political appointees loyal to the president can willfully find justification to label any research finding as scientific misconduct"

This should terrify every single scientist in America.

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.

Could be huge. Especially for those terminated in the anti-DEI purge.

Congrats Silke!

This is fantastic!

A spatial code governs olfactory receptor choice and aligns sensory maps in the nose and brain Although topographical maps organize many peripheral sensory systems, it remains unclear whether olfactory sensory neurons (OSNs) choose which of the ~1100 odor receptors (ORs) to express based upon t...

Maps are everywhere in the brain...and finally we've discovered one in the nose! Led by @davidhbrann.bsky.social, we uncovered the logic that specifies the positions of each of the 1,000 sensory neuron subtypes in the nose and aligns their projections to the brain.👇👃see more details below👃👇

Great job! Your parents must have been so proud!
I really hope you get your R01 grant funding. The research sounds fascinating and important.

Gave a talk at my parents’ retirement community to describe how science is done, and what is at stake. There was a ton of interest, and anyone can do this. Get the word out about how science affects everyone. I’m happy to share slides with anyone who asks- just get in touch! youtu.be/BY_SFgi-Cig

"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."

I think a lot about what Carl Sagan said in one of his final interviews.

🧪 Though a doubling of NSF's budget might seem far-fetched, that's exactly what Congress said what's needed to maintain national competitiveness in science & tech.

This should be shared with as many of our Republican friends as possible. They have lost their way and likely don't realize it.
