An update on my column: Parliamentary committee drops most contentious parts of its demand for data on research funding. It now wants aggregated, not disaggregated data. www.theglobeandmail.com/opinion/arti...

Le BiSP/Micrhub est sur le point de débuter à @usherbrooke.bsky.social ! Deux jours de microbiologie/bactériologie seront à l’honneur en plus d’avoir deux keynotes @lalouxlab.bsky.social et @bjesseshapiro.bsky.social. Nous avons hâte de vous accueillir! @micrhub.bsky.social #microsky

We should be paying more attention to this situation. An online letter has been put together and is being circulated to stop this data from being disclosed. Please sign the online letter here, if you are comfortable: docs.google.com/forms/d/e/1F...
