Feeling a righteous rage after ping ponging btwn doctor’s offices for weeks due to bleeding and abdominal pain.

Turns out my IUD partially expelling out of my uterus into my abdomen. Dallas Baylor ER was only place that could help me.

Women’s healthcare in Texas is very broken 😞

Hello! I’m the reporter who has been tracking citizens detained by immigration agents. And last night, I noticed something: A lot of them were at the State of the Union, including a number of whom I’ve written about.

Their stories should be known:

It was so beautiful, I cried! It’s so amazing for her to say clearly to girls that they can be in control of their own skating careers and be an artist first. 🥺🥹

Especially compared to the tragedy of the 2022 Olympics, all the girls crying, such a relief to see less of Eteri and I hope the old way of training sport will die 🙂‍↕️

Life of the Mother Archives When the Supreme Court overturned Roe v. Wade in 2022, doctors warned that women would die, but lawmakers who passed state abortion bans didn’t listen. The worst consequences are now becoming clear.

Note from the editors:

ProPublica is publishing the names of the two federal immigration agents involved in the fatal shooting of Minnesota protester Alex Pretti. We believe there are few investigations that deserve more sunlight and public scrutiny than this one, in which two masked agents fired 10 shots at Pretti as he lay on the ground after being pepper-sprayed. 

The Department of Justice said it is investigating the incident, but the names of the two agents have been withheld from Congress and from state and local law enforcement.

The policy of shielding officers’ identities, particularly after a public shooting, is a stark departure from standard law enforcement protocols, according to lawmakers, state attorneys general and former federal officials. Such secrecy, in our view, deprives the public of the most fundamental tool for accountability.

I’m taking some time to work on my health & my art first, but I’m interested in building on my work in maternal health and medical data — or exploring something completely new that sparks curiosity. If you know someone awesome and hiring, my mind (and DMs) are open 💌✨

After eight years at @propublica.org, today’s my last day. I’m deeply grateful for all the wonderful collaborators I’ve had along the way — especially my work wife @andreasuozzo.com. I’m so proud of the Pulitzer-winning work we did on Life of the Mother over the past two years.

A small number of samples can poison LLMs of any size Anthropic research on data-poisoning attacks in large language models

It’s been 5,000 years since I’ve thought about LLMs, which is where my research originally started, but this paper from the folks at @anthropic.com showing that a small, fixed number of documents is enough to poison any size LLM is really powering my brain on again www.anthropic.com/research/sma...
