Pittsburgh School of Medicine. 1) MMG (my dept): fundamental research in med micro 2) Peds ID / I4Kids institute 3) Center for Vaccine Research 🔗 to all 3 w/info: www.linkedin.com/posts/vaughn...

Very pleased to share this long term (nearly 20 years) study of yeasts isolated from vineyards and forests, now up on biorxiv: www.biorxiv.org/content/10.1...

Ella Al-Shamahi (muslim missionary turned evolutionary biologist, host of BBC human series) opinion piece on why follow the science fails. www.washingtonpost.com/opinions/202...

We are excited to share GPN-Star, a cost-effective, biologically grounded genomic language modeling framework that achieves state-of-the-art performance across a wide range of variant effect prediction tasks relevant to human genetics. www.biorxiv.org/content/10.1... (1/n)

Walunjkar, @ghaemmaghamilab.bsky.social @justinfay.bsky.social et al. profiled the proteomes of two yeast species with differences in thermal tolerance, finding a proteome-wide shift in stability, driven by both sequence change and cellular context. 🔗 doi.org/10.1093/molbev/msaf137 #evobio #molbio

New paper w/ @plos.org! @chaochihl.bsky.social identifies a unique mutational pattern among sodium azide-induced mutants. SNPs in 'CC' context and indels. Thanks to @justinfay.bsky.social @lilei0051.bsky.social @giuliafrascarelli.bsky.social @nanoporetech.com et al journals.plos.org/plosgenetics...

"We believe that mapping the damage done and its human costs—and the pushback and resilience work already underway—is necessary groundwork for building and retaining political agency"

Hitchhiking in facultative sexuals e.g. baker's yeast: can reduce diversity across the genome and contribute to Lewontin’s paradox. Results relevant to anyone (e.g. me) who has looked but found few if any strong sweeps. www.biorxiv.org/content/10.1...

All NIH study sections canceled indefinitely. This will halt science and devastate research budgets in universities.

Our work, which shows statistical issues with the previous claim of a severe ancient bottleneck in the ancestry of African populations, has been selected as a Featured article in Genetics. doi.org/10.1093/gene...

And another MIRA from @gutengroup.mcb.arizona.edu ! Please send along successful grant proposals and job apps. Seeing these is enormously helpful to folks applying for grants or jobs the first time!

Nora finished her paper with a sentence I like a lot "Our results show that even under extremely restrictive, competitive conditions, the simplest biological entities on Earth can still find paths to coexistence." There is a curious dichotomy in her experiments... 1/3 www.science.org/doi/10.1126/...

Very proud of Nilima Walunjkar’s preprint reporting her work on evolution of protein stability. www.biorxiv.org/content/10.1... This work was very fruitful collaboration with multiple members of the Fay lab, along with the Ghaemmaghami @ghaemmaghamilab.bsky.social and Phizicky labs at U. Rochester.

Great! Loved the preprint 😀, look forward to the final version. 👏 @gsherloc.bsky.social @petrovadmitri.bsky.social

How best to avoid the costs of bearing a #plasmid? Rosanna Wright @brockhurstlab.bsky.social @jpjhall.bsky.social &co find that #bacteria benefit from compensating plasmids by chromosomal (rather than plasmid-borne) mutations @plosbiology.bsky.social plos.io/3ODbXdN

For her PhD work, Carla Bautista in our group discovered that yeast hybrids adapted slower to stressful conditions, and she figured out why. See what she found here. #evolution www.nature.com/articles/s41...

🤩🦠 A new #preprint #openscience recommendation just out: Yeast consortia for novel wine fermentations by E. Pourcelot, et al. Check here: microbiol.peercommunityin.org/articles/rec... Thanks to @fcocubillosr.bsky.social for handling and @pablo-villa.bsky.social, C. Varela and 3 anonymous reviewers

Thrilled to see this paper out! 🎉 We analyzed 470 (!) angiosperm genomes and identified and dated 132 whole-genome duplication events. Importantly, we observed that WGD occurrence dates are not randomly distributed, but clustered at times of major environmental upheaval.

First post on Bluesky, let’s share some websites offering many free illustrations for scientific figures 🖼️ 🧪 🌍 : scidraw.io bioart.niaid.nih.gov www.phylopic.org More well known but very nice though: www.freepik.com
