Actual footage of me trying to explain to my child that the Bluesky outage "just happened" to occur when our paper about deaths in ICE detention was coming out:

Death rate in immigration detention has reached a 22-year-high, raising physicians' concerns A report in the medical journal JAMA said the most recent spike in deaths took place in a system with “longstanding failures” that were compounded by Trump administration policies.

New research published in the medical journal JAMA on deaths in ICE custody shows that “systemic weakness” in medical care at the agency has become more serious in the past two decades, physicians say.

DHS did not immediately respond to a request for comment about the research.

At a data science fellowship, our primary metric during code review was "WTFs per minute" so this checks out.

I hope Anthropic also tracks "oh ok yeah that makes sense" per WTF.

The Horrors That Could Lie Ahead if Vaccines Vanish Researchers at Stanford University modeled how many people could die or be disabled in 25 years if vaccines for polio, measles, rubella or diphtheria were no longer available.

NEW: Robert F. Kennedy Jr. has been transforming a government that long championed vaccines into one that questions their safety.

This is what could happen over the next 25 years if shots are unavailable even to the people who want them.

The child and a bunch of her friends got landlines recently, and I just overheard her explaining to her friend how to hang up.

"There's no button. You have to put the ear thing on the other part of the phone. No, it doesn't beep. You just put it there."

There's a service that creates an AI-generated "opposition dossier" on you before you go up for tenure so you know your weak points, potential critiques, and comparators.

Bruh — I'm sure your calculating rock can do a lot of things better than me, but I've been criticizing myself for four decades.

Users opt in and we use a smartphone app on their own devices so they can turn things on and off. Some users will request data deletion but mostly because we automatically delete their data if they don't open the app in a while. It's rare it's intentional but obviously respected when they do.

And obviously combine that with the expectation of privacy (the spatial data I have users consent to that data and we are clear we are collecting it so there's never an illusion of anonymity).

I think style is just one extracted feature. They also get the LLMs to find identifying terms like user school or subject of research, etc. I think most worrying is how little effort it takes to do tons of people. With spatial data, it's fairly easy but you need to be focused on one person/area.

I've worked with enough individual-level spatiotemporal data to know how easy it is to reidentify somebody in a "deidentified" dataset but this paper is next level scary:

JAMA RESEARCH LETTER shows US childhood vaccination exemptions. Maps show prepandemic(2010-2020) & postpandemic(2021-2024) rates by county; colors denote exemption % ranges. A graph shows county-level variation over 2 periods by state.

County-level data indicate a sharp rise in nonmedical childhood #vaccination exemptions in the US from 2010 to 2024, with post-pandemic rates highest in Utah, Idaho, Oregon, Wisconsin, and Arizona.

The letter was submitted long before the current South Carolina outbreak, but data show Spartanburg (where the outbreak is centered) has experienced an increase in exemption rates for years.

Vaccine policies work even if you don't see the consequences of their destruction until years later.

In a new, timely project led by @nathanlo.bsky.social, we collected vaccine exemption rates (mostly) at the county-level for nearly all states.

This one might be of interest to demographers! On Wednesday Amy Mann will talk about her work (w/ me and @mathewkiang.com) on metrics for measuring the quality of cause of death data. We find huge variation in quality across the US.
