New isolate genomes and global marine metagenomes resolve ecologically relevant units of SAR11

New isolate genomes and global marine metagenomes resolve ecologically relevant units of SAR11

The bacterial order Pelagibacterales (SAR11) is among the most abundant and widely distributed microbial lineages across the global surface ocean, where it forms an integral component of the marine...

Great to see the hard work of @sjtucker13 @KC_freel and @merenbey in the pubic realm. We would appreciate the thoughts and constructive criticism of our colleagues! Please also check out the companion piece: biorxiv.org/content/10.1101/…

It has been a challenge, but one of the more intellectually rewarding journeys we've been on. Congrats on getting that first thesis chapter out there, @Kolaban!

I have been broken down in a @Hertz rental car for 22 hours now. No tow truck, no replacement car..... Flat-out stranded. Had to find accommodations last night or sleep in the car. I can't believe you survive as a company treating customers like this, @Hertz.

I am very happy to report that @evankiefl's work on integrating protein structures and population genetics through metagenomics is out: science.org/doi/10.1126/scia… It yields new open-source tools, bioinformatics workflows, and insights into evolution and its governing principles.
Structure-informed microbial population genetics elucidate selective pressures that shape protein...

An integrated analysis framework shows a strong association between within-population genetic variation and protein structure.

It is with tremendous sadness that we share that our director Eleanor Sterling, passed away February 11, 2023. She was open-hearted and direct, changed our community, inspired our research, and helped us find new purpose. soest.hawaii.edu/soestwp/ann…

Imo one of the best explanations to this was by David Graeber in thebaffler.com/salvos/of-fly… "There was a time when academia was society’s refuge for the eccentric, brilliant, and impractical. No longer. It is now the domain of professional self-marketers"

Hi everyone, happy to share our discovery of an lineage of tiny bacteria associated with uncultivated, marine, pelagic choanoflagellates (the closest known living unicellular ancestor of animals):

Have any of you replaced the blue laser in your Guava Easycyte flow cytometer? Quote from Luminex is rough (unreasonably so, IMO), and so I would like to compare with others.

Is @ASMicrobiology reconsidering the #Microbe2023 meeting in Texas? Between the lack of gun regulation, and copious policy against women, people of color, non-US nationals, members of the LGBTQIA and trans communities, etc., going to Texas is not safe for any of my lab members.

Looking to amplicon 16S sequence a small number of samples, and don't have a full MiSeq run planned any time soon. Can anyone recommend a seq center that will take individual samples? Thx!
