Exciting news: @uwgenome.bsky.social will be hiring for two tenure-track faculty positions this year, one open rank and one assistant professor. Both are “Genome Sciences” interpreted broadly so we welcome applicants working in a variety of fields and methods. Ad will be out shortly.

Check out our preprint on Duckweed combo-stress responses and chromatin accessibility. ACRs have ⬆️ GC content much like maize, even with small genomes and low TE numbers. One speculation we had for this in maize was TE insertion avoidance, guess we were wrong. www.biorxiv.org/content/10.6...

In nature, plants experience complex combinations of environmental stresses. Prior studies using Arabidopsis thaliana show that transcriptional responses to combinatorial stress are unique and cannot ...

Updated version of our preprint about mutations in URA6 causing 5-FOA resistance in S. cerevisiae, now including new metabolite profiling data! www.biorxiv.org/content/10.1...

URA6 mutations provide an alternative mechanism for 5-FOA resistance in Saccharomyces cerevisiae
The URA3 gene is frequently used in the budding yeast community as the mutation target for 5-fluoroorotic acid (5-FOA) resistance. We identified a class of ura6 mutants that can grow in the presence o...

A new blog post thinking through the parallels between protein structure prediction and virtual cell efforts. Many of our current approaches to collect data to build a virtual cell model lack the abstraction that links measurement and function. t.co/4sPSMaLWLL

“The message, very clearly, they’re sending is, do not speak out on behalf of Chinese postdocs. If you do, you’re going to pay a penalty...It seems pretty obvious that this is an attempt by the current administration to silence people that question their activities." — Roger Innes, IU AAUP member

@vram142.bsky.social So are pioneer TFs displacing or moving nucleosomes? Or is that an unanswerable question.

Continuing efforts to hurt the research pipeline, the very late NSF GFRP solicitation no longer allows 2nd year PhD students to apply. Lots of these students chose not to apply last year because they were told they would have a better change once in their thesis lab www.nsf.gov/funding/oppo...

The GRFP announcement from NSF cuts out an entire cohort of 2nd year students from consideration, without warning. This is so deeply unfair that it warrants a formal protest from the scientific community. If someone wants to work with me to craft an open letter and solicit signatures, LMK.

Here ends our foray into rDNA variation in model organisms—w/ Christine Queitsch, Bonnie Brewer, and many others. Especially Ashley Hall and Elizabeth Morton. tl;dr: In natural ranges of rDNA copy number, phenotypes are rare (yeast + C. elegans). But outside those ranges? Some things happen. 1/3

Proposed cut to NSF Biology budget is 70%. 70%. Seventy. Call your senators & reps nonstop. Give them numbers on NSF impact for state/district. tableau.external.nsf.gov/views/NSFbyN... explain this will decimate the economy if their districts, especially if it has a major research univ. 🧪
