Our results indicate that extended periods spent in poorly ventilated classrooms may be a stronger driver of within-school transmission than individual contact rates.

We found that while close contact contributed to elevated risk (rate ratio 1.16 per doubling daily time, 95%-CI 1.01–1.33), time spent in shared classrooms and poor air quality had larger effects (RR 3.17, 95%-CI 1.96–5.17 and RR 1.90 95%-CI 1.23–2.94) respectively).

5 papers from the Super Bowl of Economics Planet Money went to the annual meeting of the American Economics Association, and we saw some fascinating papers presented there.

There's still time to include this in your FRPA.

Visiting Assistant Professor of Computer Science Haverford College invites applications for a full-time Visiting Assistant Professor of Computer Science.

We're hiring multiple faculty positions! Full time positions in CS for 1 or maybe 2 years.

We care about and support both teaching and research, and past visiting faculty have gone on to TT R1 and SLAC jobs. We're located near Philadelphia.

Happy to answer Qs!

Are you (or do you know someone) recently graduated from undergrad looking to beef up your skills and experience prior to starting grad school/career? Do you like social drama and parakeets? Come join my team! I'm looking for two people to start very soon!! tinyurl.com/59rf8jcy

BOGO offer: Submit a "research paper" with a hallucinated citation, and earn an auto-rejection for all of your papers this year and next!

This is remarkable and insane dereliction of integrity...

Good god...

TIL "usufruct" is a word. Means the right to enjoy use of someone else's property without destroying it.

Latin roots: usus et fructus (use and fruit/enjoyment)

FYI, in case this is useful! Norovirus (should it be the culprit) requires that you use bleach for surfaces, and alcohol-based hand sanitizers aren't going to work. Good luck and hope you guys are better soon. 🤞

Interpreting Breakthrough Infections Given Assortative Mixing of Partially Vaccinated Populations Declining vaccine coverage across the United States has increased the risk of outbreaks of vaccine-preventable diseases. Even when vaccines have low primary failure rates, conventional epidemic theory...

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

Statistical methods for estimating the protective effects of immune markers using test-negative designs Abstract. While widely used to study vaccine effectiveness, test-negative designs (TNDs) also provide a platform for identifying and quantifying immunologi

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.

Santa Clara County runoff turnout dropped 53%. Ranked choice voting is the solution. - FairVote Santa Clara County, CA's runoff for county assessor cost taxpayers an estimated $13.1 million, and turnout declined by 53%

On Dec. 30, Santa Clara County, CA held a $13 million runoff for county assessor.

Turnout dropped 53%, and the winning candidate got fewer votes in the runoff than in the general election.

All of this could be avoided w/ #RankedChoiceVoting. @calrcv.bsky.social ⬇️

Thank god at least *some* of our poor domestic billionaires will get increased exposure to TikTok profits, even if ByteDance still controls the algorithm's hooks from afar.

This seems tricky. I don't really know what all my former collaborators have gotten up to over time, so do I need to track whether they'll benefit now from my current research? I might be with @dsky.bsky.social on this one...

News to me! Must be quite a recent change, as archive.org from the end of 2025 doesn't have the new language. Interesting change.

And then we'd get a massive secondary market of...shell companies.

A diagram showing the matrix LED system on the left, where the headlights create a cone of darkness around other vehicles to avoid blinding them -vs- the conventional system on the right, where the headlights are always on in all directions.

This is the picture I have in mind.

I'm hopeful for the proliferation of matrix headlights... But I don't *really* know that much about their failure modes or downsides.

Can they just be a little less bring and more pointydowny?

E.P.A. to Stop Considering Lives Saved When Setting Rules on Air Pollution

Whaaat?! The EPA's cost-benefit analysis of air pollution regulations can only consider costs to businesses but not health benefits?! This is nonsense.
