Our latest set of GCBR Organization Updates is our longest issue yet, featuring statements on AIxBio risks, RFPs for clean indoor air, hiring for biosurveillance, resilient synthesis screening, and more!

US health agencies like CDC and NIH and FDA remain full of dedicated and exceptional scientists and health professionals doing the right thing for public health. But this example shows they can be overruled by an exceptionally unqualified secretary of HHS.

I'm fortunate to live in a state with a high-quality health department that provides information based on science. For those who don't I recommend Canadian canada.ca/en/public-heal… or UK gov.uk/government/org… advice.

Don't post much here any more but this is worth commenting on statnews.com/2025/05/27/cov…

I just joined APHA bit.ly/3tPy1KU -- a strong advocate for public health right now. Encourage others to do the same!

@_akiraendo I’ve had that experience with Cell and with Scientific Reports. Maybe a good reason to avoid donating your labor to that journal! And tell them Why

Just realised that a manuscript I flagged a serious issue for was published without re-review (or even a notice), where the authors' response to my comment was essentially "don't know what you mean" 🙄

We will kick off the @ColumbiaMSPH seminar series on infectious disease modeling in the spring semester with a fantastic talk by Dr. Marc Lipsitch @mlipsitch from @CCDD_HSPH @HarvardChanSPH! Welcome to join in person or over Zoom on 1/21. Register here: @columbia.edu&recurrenceId=" target="_blank" rel="nofollow noopener">events.columbia.edu/cal/event/even…

Excited to share a new preprint led by Indra Gonzalez Ojeda on a new tool to improve pangenome calling in bacteria, CLARC. biorxiv.org/content/10.110… . Passing output of Roary for S. pneumoniae populations through this tool reduces accessory genome > 30%, resolves other puzzles

A new CDC report shows how real-time modeling can spot COVID-19 surges early, aiding early public health action. Learn more: bit.ly/mm7346a3

Interested in causal inference and #IDEpi? Come and join the @DGEpi and @gmdsEV IDEpi’s working group workshop in Hamburg on December 12th & 13th. With @mlipsitch of @HarvardChanSPH , #WillHulme of @UniofOxford and @UweSiebert9 of @UMIT_University! 👉 bit.ly/CausalInferenc…

@EllenFoxman @YaleIBIO @Yale_LabMed @YalePediatrics @JohnsHopkinsSPH what a cool study! Congratulations!

Shout out to the great team @YaleIBIO @Yale_LabMed @YalePediatrics and @JohnsHopkinsSPH that made this project happen. Grateful to have gotten to know Prof. Diane Griffin, who unexpectedly passed away while this paper was in press, leaving an inspirational legacy behind (8/8) publichealth.jhu.edu/2024/in-memori…

The measles vaccine is given as a shot but it is surprisingly good at inducing protective immunity in the respiratory tract (mucosal IgA). Our new study @YaleMed and @JohnsHopkinsSPH provides some clues about why...a thread (1/8) academic.oup.com/jid/advance-ar…

@ItaiYanai Thank you @ItaiYanai . It's finding gems like this that keeps me resisting the impulse to quit X.

Doing good science is 90% finding a science buddy to constantly talk to about the project.

My profound thought for today: Jargon and buzzwords are opposites. Jargon are words almost no one uses that have precise meaning. Buzzwords are words everyone uses that have little meaning. Clarity is avoiding both.

Trump’s Project 2025 explained hilariously, terrifyingly, and perfectly. Trump’s Project 2025 will end America as we know it and turn it into the White Christian Nationalist version of Afghanistan. twitter.com/naretevduorp/s…

Just out w @chrisbboyer academic.oup.com/aje/advance-ar… Emulating target trials of postexposure vaccines using observational data. Spurred by great collab with @nycHealthy on mpox vaccines, but applies to any postexposure intervention on an infection to reduce risk of bad outcomes.
