‘Proactively fall in line:’ Holocaust Memorial Museum quietly changed content after Trump returned to office Two former employees said they believed the museum was altering its content preemptively to avoid unwanted negative attention from the Trump administration.

After Trump took office last year, the US Holocaust Museum quietly removed educational material about American racism from its website and canceled a workshop on the "fragility of democracy," @iriesentner.bsky.social reports. www.politico.com/news/2026/04...

I’m running for Congress in my home, New York’s 12th Congressional District, because the federal government is destroying the very systems that keep people safe. Our rights and guardrails of democracy are at risk. We need people who will deliver results.

That's what I'll do: ninafornyc.com

I can't believe Katherine Johnson used to do these sorts of calculations and simulations BY HAND. I'm flabbergasted.

The Problem With Promoting ‘Gold Standard Science’ Opinion | Branding scientific research with a simplified label risks misleading the public and harming scientific literacy.

Federal agencies have been labeling some research "gold standard science" — a trend that accelerated after a May 2025 executive order. Researcher Jonathan P. Scaccia argues the branding distorts how evidence actually works.

Fertility awareness-based methods (FABMs) are important options within the full spectrum of #ReproductiveHealth care. By grounding FABMs in evidence and reproductive justice, we can strengthen the fight to ensure access to care for all.

I feel so lucky to have been in school with so many brilliant international students. The son of a Ugandan mango farmer helped me survive statistics class, & the varied perspectives I was exposed to enriched my science immeasurably. This is truly our (the US's) loss.

I'm reminded of these wise words from Mr. Fred Rogers on what would have been his 98th birthday. We are all in this together. Let's renew ourselves to the fight for the common good. It's all the more important during these difficult times.

THREAD: Cherise Doyley was in her 12th hour of contractions at the hospital when a tablet was brought to her bedside.

On the screen was a Zoom call with a judge and several lawyers and doctors.

She was in court, a nurse told her. The reason? For failing to agree to a C-section.

Yeah.

But once it's in a journal, stopping it from "starting" to catch on is pretty hard, too. Ask me how I know 🫠

Whew.

Apropos of absolutely nothing, here is a slide from a talk I delivered yesterday on addressing mis- and disinformation in the published scientific literature.

Wakefield's paper, of course, had been published in the Lancet, where Richard Horton was, and remains, Editor in Chief.

This special issue isn’t anti-tech. It’s about ensuring that innovation serves people’s needs, not just market incentives.

The path forward requires collaboration across technology and health, rigorous evaluation, and an unwavering focus on reproductive health, rights, & justice.

Vast majority of special issue submissions came from high-income contexts.

Despite FemTech collecting data from millions daily, only ~50% of submissions included empirical data.

FDA recently signaled it may relax regulation of health tech, but we need stronger (not weaker!) safeguards.
