Grievance Is All You Need .... understanding attacks on NIH, CDC and FDA through the lens of COVID revisionists: joshuasweitz.substack.com/p/grievance-...

I use this (overly simplified) schematic to explain to folks why maintaining high measles immunity is so hard. Even with 100% coverage, you get different outcomes depending on who and when you vaccinate. Consider a population with more kids than adults -- start with them all being susceptible.

Superb reporting from @katherineeban.bsky.social for @rollingstone.com on the scandal around the RFK-fueled, unethical HBV vaccine study in Guinea Bissau that horrified CDC staff, scientists and ethicists around the world. www.rollingstone.com/politics/pol...

Uptick in mumps in MD: 19 cases, 7 probable so far in 2026. Compared to 21 total cases across the period 2022-2025.

Check out this @nature.com News explainer article on measles, with my comments about our prior work, and featuring an upcoming article led by Drs @malar0ne.bsky.social and @joshuasweitz.bsky.social: www.nature.com/articles/d41...

If you (or a mentee) are a NSF GRFP applicant in the life sciences who had a submission Returned Without Review, I'd be interested in hearing your story. I'm a reporter at STAT News, and my email is [email protected]. I'm also reachable via Signal (username jwosen.27) #journorequest

The "Ten New Insights in Climate Science (10NICS)" is an impressive project that leads to a very high-profile policy relevant paper each year. Get involved if you can (details in the attached message from @daniel-ospina.bsky.social)!

We have a lot of fun here at colin carlson dot bluesky dot social but let's go inside the bit for a second. If NSF fails to pay out the annual increment of the @viralemergence.org center grant a third time in six months, there is literally nothing I can tell my team about why they shouldn't quit

The Chesapeake Bay is starting to freeze—today's map, issued by the National Ice Center, shows fast ice in the tidal fresh rivers at the head of the Bay, and on the Potomac off of Washington, with coverage expanding toward the south.

Models can be powerful tools to study associations in data. But do they reliably reveal the truth? 🚨 In our new study, @danlarremore.bsky.social and I show that the model used to estimate VE from test-negative designs (TNDs) may not translate to other correlates of risk. doi.org/10.1093/aje/...

In a new preprint, we combine modeling with school-level vaccine data to contextualize the risk of 'breakthrough infections' and impacts on the ongoing US measles outbreak. #idsky #episky www.medrxiv.org/content/10.6...

Please please vaccinate your child against measles. This is from our @independentsage.bsky.social report from last year, led by @trishgreenhalgh.bsky.social & @helensalisbury.bsky.social independentsage.org/wp-content/u...

imagine if all that money had gone to teachers instead

Our latest study in @jama.com on trends in county-level vaccine exemptions, demonstrating geographic pockets of high vaccine exemptions and high susceptibility to vaccine-preventable diseases. Great collab with @nbcnews.com colleagues and our Stanford team. jamanetwork.com/journals/jam...

We have a new paper in Science today on how malicious AI swarms can threaten democracy. AI systems can already coordinate autonomously, infiltrate communities, and fabricate social consensus. www.science.org/doi/10.1126/... Led by @kunstjonas.bsky.social & @daniel-thilo.bsky.social!

We're looking for a full-stack developer! Help us build the best open data platforms for pandemic prediction in the world. Probably a short-term contract, but if you're looking for a full-time gig, let's talk. Inquire within: www.viralemergence.org/blog/were-hi...

Viruses transform microbes, populations, & ecosystems. In new work jointly led w/@tn-marine-micro.bsky.social + more, we find a link between enhanced viral infection and productivity 50 meters below the surface in the otherwise nutrient limited Sargasso Sea. a 🧵 www.nature.com/articles/s41...

NEW article by me! We can now visualize pathogens down to atoms; design vaccines in weeks; manufacture them in microbial factories; engineer them more precise than ever before. We're living through a golden age of vaccine development, but only if we continue to invest in them.

As with everything he says, this is wildly uninformed. Formula keeps getting better and saves lives. And modern research indicates that outcomes are roughly the same. There are reasons to breastfeed but your child isn’t suffering if you don’t

The MIDAS Trainee Executive Committee is recruiting new members for 2026! 🤓 This is a great opportunity for grad students & postdocs in infectious disease modeling to gain experience organizing events & connect with peers. Applications are due by 9am ET on 1/1/2026, link in flyer & alt text.

My first lead author paper is out with Ben Kerr and @alisonfeder.bsky.social! We found that making an antiviral too strong can sometimes make resistance easier to evolve. This has implications for how we design drugs, choose doses, and think about viral evolution in the face of treatment. (1/n)

Really nice paper on Universal differential equations in systems biology with some nice looking #julialang code. www.nature.com/articles/s41...

Cutting, delaying, and terminating science funding comes with costs to... discovery, projects, and people. One more example of impacts: to a NSF-funded Biology Integration Institute. It is well past time to restore expert-driven decision-making & stable budgets to NSF, NIH, CDC...

The #AIDS pandemic isn’t over as millions still living with #HIV On #WorldAIDSDay Geoff Garnett explains success over past 30 years in danger of being reversed as disinvestment in HIV treatment & prevention will lead to more AIDS deaths & spread of HIV. www.lshtm.ac.uk/newsevents/e...

"All of this falls apart if humans don't adopt the tech. This is why you've seen Meta cram its lame chatbots into WhatsApp and Instagram. This is why Notepad and Paint now have useless Copilot buttons on Windows. This is why Google Gemini wants to "help you" read and reply to your emails."

It’s widely known (and, I think, pretty uncontroversial) that learning requires effort — specifically, if you don’t have to work at getting the knowledge, it won’t stick. Even if an LLM could be trusted to give you correct information 100% of the time, it would be an inferior method of learning it.

Thanks to all who came out to discuss impacts of federal cuts to science, our work via scienceimpacts.org, and how to constructively speak out with grassroots initiatives: @standupforscience.bsky.social, @sciencehomecoming.bsky.social @snapcoalition.bsky.social Impact Project + more a 🧵
