New feature to help plan Modular Cloning (Golden Gate) experiments and streamline the otherwise confusing dance of overhang compatibility and vector hopping. Gonna find some time to try this out and compare to my current SnapGene workflow. Tools all day!

You go, Katy! 🚀
I’m so proud of you, and so happy to finally see this in its final form!

Count me in on your corner to keep on cheering for you! Looking forward to doing more amazing science together 💪

You go Katy!!! 🚀
It's so nice to see this finally out!
So much hard work to communicate amazing findings in such a nice output! 💪🏽

Congratulations! 🎉

Widespread and intron-rich mirusviruses are predicted to reproduce in nuclei of unicellular eukaryotes - Nature Microbiology Environmental metagenomic explorations show that Mirusviricota lineages lack essential replication and transcription genes and contain spliceosomal introns, suggesting nuclear reproduction.

www.nature.com/articles/s41...

Thrilled to share our new study! We show that mirusviruses include lineages packed with spliceosomal introns and likely replicating in the nucleus of unicellular eukaryotes—a sharp contrast to most large and giant eukaryotic viruses that replicate in the cytoplasm.

Comparison of virus-host prediction from Hi-C and in silico tools. Top: Eular plot showing the overlap of viruses with host predictions obtained from the experimental Hi-C linkage approach, or one of two in silico tools (iPHoP and VirMatcher) that use different probabilistic models to aggregate output of various sequence-based features to create host prediction scores. Bottom: Comparison of virus-host predictions across all samples between Hi-C and iPHoP, shown with and without applying a Z-score filter for the Hi-C linkages. Black bars indicate congruent predictions identified from both tools and gray bars indicate non-congruent predictions. Note: Although many viruses had multiple predicted hosts from each tool, only the top-scoring prediction for each virus was considered in this comparison.

#Virus discovery has accelerated but linking viruses to hosts is hard. @sullivan-lab.bsky.social use synthetic #microbiomes to optimize & benchmark #Hi-C for virus-host linkage inference, applying this to existing #soil data to reveal 100s of novel linkages @plosbiology.org 🧪 plos.io/3MlAENO

Awesome work! Congratulations to you all! 🎉

🚀New preprint from our lab!
I am very excited to finally share what has been the main focus of my PhD for the past almost 3 years! It is about viral dark matter and a powerful tool we built to shed light on it. 🧬💡

The Drain of Scientific Publishing details very clearly how for-profit publishers making >30% profit margins have corrupted any solution the research community has attempted.

Anecdotal, but a lot of highly trained immigrant PhD colleagues and friends have been moving back to their home countries this year.

Every one of those said the reason was safety

Of the 10 defense systems originally discovered in Doron et al 2018, Kiwa was one of the last to be studied - until now

Kiwa is a membrane-embedded complex activated in phage attachments sites to degrade phage DNA

A nice study by the Nobrega lab
