some philosophers use biological science concepts with mastery; some others do not. I was reviewing a quote suggesting an opposition between symbiosis and Darwinian evolution. do some of you agree with it? 🤔

Working on a new plant bacterial disease report! However, there’s a 2015 genome announcement of a bacterium from the same genus causing disease on the same plant as my work... 🤔 I obviously decided to compare 🔎.

Elementary 3D organization of active and silenced E. coli genome - Nature
An ultra-high-resolution chromatin organization map of E. coli, using Micro-C, reveals intricate chromatin structures involved in the silencing of horizontally transferred genes and those associated with active operons.

Sharing good practices: I received this essay through the @aspbofficial.bsky.social newsletter. I recommend it if you, like me, are entangled in multitasking and several research projects

I'm on those days when you want to do many things, but these things don't want the same. I had trouble even in preparing an agarose gel 😥. A nice day to work on the enlightenment of "things have their own time"

I wish more Brazillian colleagues on federal institutions were on Bluesky to see this example...
Considering the Federal situation, campuses are encouraging labs to enter partnerships with industry.

A plant breeding company reached out to see if my lab could rate their plant lines for their resistance to Ralstonia. I said "maybe, but these assays require personnel time and materials"

🚨 Our new paper is out in Science!
We analyzed 2,723 high-coverage whole genomes from Brazilians to explore how five centuries of colonization, forced migration, and admixture have shaped genetic diversity and impacted health.

Admixture’s impact on Brazilian population evolution and health
Brazil, the largest Latin American country, is underrepresented in genomic research despite boasting the world’s largest recently admixed population. In this study, we generated 2723 high-coverage who...

reading and writing have always been some of my favorite parts of being a scientist. however, during grad school, most of my writing happened under a time pressure (mostly self-imposed 😵‍💫). now, I’m hoping to shift gears: writing with more pleasure and less pressure🧘‍♂️
