New preprint drop! I think this fun little story on Berkson's paradox will become essential reading for computational biology/genomics, where I think it commonly occurs but is poorly known. www.biorxiv.org/content/10.6...

Call for a group leader in Evolutionary Biology The IGFL @igflyon.bsky.social in Lyon, France, is recruiting a group leader in Evolutionary Biology. An exciting place for exploring the interfaces of evolution with physiology and development. #EvolBiol #ecoevo #evodevo tinyurl.com/evolbiol
Recently, @gladfelterlab.bsky.social said to me: "You may think you're done with condensates but condensates are not done with you." Amy, you are so right. @dadrummond.art has not yet been reached for comment.
Boost your yeast transformation efficiency 🚀🚀🚀!!! In the latest Yeast review, Alistair Elfick & @ewjwallace.bsky.social discuss approaches that may enable superefficient transformation of S. cerevisiae, and accelerate genetic manipulation of non-model yeasts. onlinelibrary.wiley.com/doi/10.1002/...
No-one knows how yeast take up DNA in transformations. Really! (Ok, endocytosis is required.) We noticed that "yeast transformation mix" w/ Lithium salts, PEG, carrier DNA ... is exactly the mix that chemists use to make DNA phase separate. Our review paper in Yeast Journal! w/ Alistair Elfick 1/

Postdoctoral position available! Help us to understand how fungi cause disease, by bringing data-driven engineering biology and cool fluorescent protein tools into fungal pathogens. Details: ewallace.github.io/news/postdoc... Please share!
Yeast colleagues: any idea what @zymoresearch.bsky.social do in their frozen yeast transformation kit for or instead of carrier DNA? zymoresearch.eu/products/fro... Kit looks great and is highly cited, I'm wondering about publicly available info ideally that I can cite in a review paper.
Bunsen burners limitations in aseptic technique! Data-driven evidence here in a neat and careful study For what it's worth, the senior author Hannah Gavin is a lovely human who I used to occasionally play music with in Chicago.
As a component of aseptic technique, Bunsen burners do not universally decrease deposition of microbe-containing particles journals.asm.org/doi/full/10.... #jcampubs

Postdoc/staff scientist/ in computational biology and evolutionary genetics? Alex Cope is very good. I've collaborated with him for years. First author publications, all technically great, some in glam journals. A great team player and nice guy too. scholar.google.com/citations?us...

Introns have a hidden regulatory role! 🧬🎉 Delighted to share our latest paper showing that inefficiently spliced introns and spliceosomal proteins direct RNA methylation, engaging RNAi to silence retrotransposons and regulate gene expression nature.com/articles/s41...

What's the state of genomes that report on early animal / holozoan evolution? A student project in my lab on evolution of RNA-binding proteins is testing the hypothesis of a gene duplication in early metazoa, we want to look for homologs in in holozoa beyond Monosiga. @jlsteenwyk.bsky.social ?

I worked for UKRI for seven years and in my experience, the short timescales were 100% because of delays in central government. Usually because of delays in sign off by a minister; in the worst cases, due to number 10 comms teams insisting we hold back so the PM could announce it or whatever. 1/3
A new TOP FIVE has just dropped. The @ukri.org TOP FIVE shortest timescales from call opening to closing. And you won't believe the winner 👀

Save the date : Seminar by Edward Wallace from the University of Edinburgh on Tuesday 12th May at 11h @ewjwallace.bsky.social @edinburgh-uni.bsky.social
How do fungi grow directionally? We think part of the mechanism involves local translation of mRNA near the tip, especially of cell wall components. Delighted to share our preprint showing that an RNA-binding protein, SsdA/Ssd1, is trafficked to the tip of growing fungal filaments.
Happy to share that the bulk of my PhD work is now on bioRxiv! We followed SsdA, the A. nidulans ortholog of yeast RNA-binding protein Ssd1, and found it forms motile mRNP puncta in hyphae. [1/7] www.biorxiv.org/content/10.6...
The work is a tour-de-force from the PhD of @dmodaffari.bsky.social, co-supervised with Edinburgh colleague Ken Sawin. Domenico set up Aspergillus nidulans in the lab, did beautiful hypothesis-driven imaging experiments, and generally learned everything from everyone then did it even better.
Look out for Domenico, whose next destination is a postdoc with @samreckpeterson.bsky.social ! The Reck-Peterson group's work on cargoes hitchhiking on endosomes, and their discovery of adaptors PxdA and DipA, inspired some of this story showing that mRNA-protein complexes also hitchhike.
I am learning a lot from this debate about the last eukaryotic common ancestor. It's thought-provoking to have competing hypotheses and perspectives argued out there in the open. Here, the two arguments are internally consistent, yet different conclusions... so where's the wrong assumption?
I appreciate the comments by Max Raas, Eelco Tromer and others on my paper published last year "Hypothesis that ancestral eukaryotes sexually proliferated without kinetochores or mitosis". However, I do not think their critiques can reject my hypothesis. For details, please read the paper. 1/n
Today's @gautamdey.bsky.social seminar on Evolutionary Cell Biology is mind-blowing in so many ways. Dinoflagellates don't have histones!?!?! And BEAUTIFUL microscopy.

New preprint! This work is Gabriela Fior Ribeiro's second first-author manuscript, @logantom.bsky.social's first manuscript, and is the culmination of our long-standing collaboration with @ewjwallace.bsky.social's group at University of Edinburgh. www.biorxiv.org/content/10.1...

V happy with paperpile as a reference manager. Thanks @dadrummond.bsky.social for that recommentation.
What do people use for references in Google docs/word? Coming from latex where referencing was solid, have been stung a couple of times by Google docs/zotero losing or messing up which paper each reference number points to. This is too painful to go through again. What are the alternatives?

It’s actually even worse: they show it as a gel, which is pure fluorescence units, but a BioAnalyzes records as the molecules pass a single point sensor and critically _fails to normalize for different molecule speeds_ This results in a near-logarithmic overcounting of large molecules!
This is your regular reminder that the BioAnalyzer/TapeStation reports fluorescence units, not # of molecules. Left is bioA trace, and right is fragment size calculated from either read output (blue) or transformation of BioA trace (black). Fig 3 from journals.plos.org/plosone/arti...
