A Grammar of Graphics for Comparative Genomics
An extension of ggplot2 for creating complex genomic maps. It builds on the power of ggplot2 and tidyverse adding new ggplot2-style geoms & positions and dplyr-style verbs to manipulate the…

Mike Blazanin@mikeblazanin.bsky.social · last yr.Excited to see this new, and extensively-rewritten, version of our preprint up now! With @paulturnerlab.bsky.social we show how bacterial population dynamics (e.g. growth curves) can be used to accurately quantify bacteriophage infectivity 🦠 🧫🔬 #microbiology #VirEvol doi.org/10.1101/2023...
Happy World Phage Day! Tiny viruses have mighty roles, shaping our environment and life on Earth. Phages maintain microbial community stability, impact primary production, nutrient cycle and pathogen virulence. We can also use phages in phage therapy to combat bacterial infections. #PhageSky
Feels surreal to say but: I'm hiring! If you are or know anyone interested in looking at the evolution of phage resistance using A. baumannii and natural transformation, then this might be for you www.jobbnorge.no/en/available...

Going to ASM Microbe 2025? Check out the in-depth symposium "Phage Ecology: From Prophage Decision Making to Ecosystem Modulation" hosted by Dr. Hernandez (@cathyhernandez.bsky.social) and I! We have some really cool talks lined up. Hope to see you there! 🧪🦠🔬 #Phagesky #Microsky
Hello everyone! I am pleased to share information on the first ever Computational Structural Virology Symposium, conducted August 4th on zoom and highlighting work in this emerging field. You can register for this event here: forms.gle/CNiqskMwQEuV.... Please re-post!
It's out! We used the T4P-dependent phage Luz19 to select against the type IV pilus virulence factor in P. aeruginosa, despite the presence of competing S. aureus.
James Gurney@jamesgurney.bsky.social · last yr.Big day for the Gurney lab, first paper from the lab is now published. @sczerwinski.bsky.social led this work and answered a simple question does phage steering work when other bacteria are around? Tldr: yes! journals.asm.org/doi/epub/10....

Beautiful video of inter-cellular signaling in a swarming response that I pulled from the other place, produced by @strickland-evelyn.bsky.social in collaboration with D. Irimia lab. The dye detects calcium flux that indicates a signal being received by each cell: you're seeing the 'alarm' go out.

We developed a microscopy-based technique🔬 to measure attachment of viruses #phages to host cells. 🦠 The paper was posted online today: www.pnas.org/doi/10.1073/... #phagesky #microsky
I had images in my head of what I wanted to capture on my recent adventure to the southern USA. I wanted storms and sprites with Bayou foregrounds. Man, it is a tough place to chase- dark skies are hard to find as are accessible, treeless areas to get a view.
Happy to see this out now in @asn-amnat.bsky.social! We combined experimental evolution and mathematical modeling to ask: can bacteria evolve to swim away from their viral parasites? 1/n #evosky 🦠 #phage 🧪 (gift link:) www.journals.uchicago.edu/eprint/TETM9...

Is anyone knowledgeable, or knows someone that is, about deciduousness in conifers? I’m curious what were the selective pressure(s) and evolutionary pathways that result in it. I’ve seen a few Tamarack larch (Larix laricina) here in Alaska, they’re amazing!
It’s my first time in Alaska and I’m enthralled. The temperate rainforest and rapid ecosystem shift as you move from coastline to jagged peaks is fascinating
