What is the best strategy to win any contest?

Eliminate your opponents of course.

Recently, my friend @fernpizza.bsky.social showed how plasmids compete intracellularly (check out his paper published in Science today!). With @baym.lol, we now know they can fight.

Presenting Dr. Daria Evseeva! Daria defended her thesis at @mpi-bio-fml.bsky.social last week and earned her doctorate - with distinction! She worked on a historic outbreak of Ralstonia in Martinique, the origins of the banana outbreak in Indonesia, and the evolution of intermicrobial antagonism.

One of my favourite serendipitous results from the lab came about because we were long-read sequencing bacterial:

Vibrio cholerae, which is "supposed to" have TWO circular chromosomes (3 + 1 million base pairs) often has just ONE fused chromosome (4 Mbp).

This has been in the works for a while, and is not a response to recent events, but the timing couldn't be better: Canada now allows foreign students and postdocs to apply for more doctoral and postdoctoral fellowships! www.nserc-crsng.gc.ca/NewsDetail-D...
NSERC - Latest News - Launch of the new Harmonized Tri-agency Scholarship and Fellowship programs
As announced in Budget 2024, the scholarship and fellowship programs administered by the three federal research funding agencies – the Canadian Institutes of Health Research (CIHR), the Natural Sciences and Engineering Research Council (NSERC), and the Social Sciences and Humanities Research Council (SSHRC) – have been streamlined into a new harmonized talent program called the Canada Research Training Awards Suite (CRTAS) that will open for applications in summer 2025.
