White House stalls release of approved US science budgets The US Congress rejected sweeping cuts to science agencies. But the NIH, the NSF and NASA have had their spending slowed.

Congress rejected massive cuts to US science budgets for 2026, but much of the money still isn’t flowing to researchers.

The culprit? The White House Office of Management and Budget (OMB) is quietly slow-walking the release of funds. πŸ§΅πŸ‘‡

How to Set Up and Run an Undergraduate Research Lab APS Fellow Julia Strand offersΒ resources and recommendations to run a productive research lab.

Just outβ€”a piece I wrote a piece for the APS Observer (@psychscience.bsky.social) in which I share recommendations and resources for running a research lab at a small, liberal arts college. I hope it helps others in the same boat! www.psychologicalscience.org/publications...

Amid these dark moments, something important is beginning to shift.

It's clearly the result of healthy political pressure - which we must sustain, and build.

I Set A Trap To Catch My Students Cheating With AI. The Results Were Shocking. "Students are not just undermining their ability to learn, but to someday lead."

To β€œmy students and to anyone who might listen, I say: Don’t surrender to AI your ability to read, write and think when others once risked their lives and died for the freedom to do so.”

PIWI clade Argonautes are essential for transposon silencing. Without them, animals are sterile due to massive transposon activity.

But how does piRNA-guided target interaction translate into silencing?

PhD student JΓΊlia Portell Montserrat has an intriguing answer

Lepidopteran Genomes Have Denser Transposable Elements in Smaller Chromosomes, Likely Driven by Non-allelic Homologous Recombination Abstract. Transposable elements (TEs) drive major genome size and structural variations, yet evolutionary forces affecting their accumulation and removal r

An & Nam investigated chromosome size and TE organization in ten butterfly species, showing lepidopterans have denser TEs in smaller chromosomes, with nonallelic homologous recombination as a potential driving force.

KUnion Busting: 427 Days Without a Contract Over a year after winning their union, there is still no contract in sight for faculty and academic staff as KU management stalls negotiations.

Do orally secreted REPATs to belong to a specific clade? use proteomics on saliva. Most proteins found in paralogous clades.

SelV1 infection reduces the abundance of some REPATS. SelV1 infection modulates plant response to caterpillars.

First perform manual annotations and phylogeny. MBF2 domain is absent in clade in Spodoptera only.
two clades: "one to one" and another clade "many to many" with extensive paralogs.

But many REPAT proteins were initially found in REsponse to PAThothens.
So REPATS are important in insect-plant and insect-pathogen interactions. Is there a 3-way interaction here?

Effector proteins from saliva interact with plants to suppress defense. A recently discovered class include REPAT.
REPAT are co-transcription factors, enhance gene action that suppress Jasmonic Acid pathways.

kmo-KO have much less diversity in fore & mid, but not hind. Consistent with observation for more HQA in fore & mid gut.
