1/ Just in: An anonymous federal worker has filed a whistleblower disclosure warning that the U.S. Postal Service's attempt to create a system to regulate mail voting for the midterms has been "rushed, chaotic, and fundamentally flawed." @propublica.org has the details 👇

Screenshot of the top of a whistleblower disclosure titled "USPS Rushed Implementation of New and Untested IT Systems Threatens U.S. Ballot Mail Delivery." Addressed to Senator Blumenthal, the first point details how the whistleblower has "significant concerns about the USPS's secretive, rushed, chaotic, and fundamentally flawed process for the creation and implementation of an entirely new and untested set of IT systems" intended for the 2026 midterms.

I'm a staff writer at @wired.com and I'm looking to speak with parents of immunocompromised kids, especially those in areas with measles outbreaks, and how you're dealing with back to school with rising cases. emily_mullin@wired.com

Every conversation about bike lanes is like: "Car crashes kill a huge number of people every day, including pedestrians, cyclists, & car occupants. Good bike infrastructure has been shown to make everyone safer (& doesn't increase congestion)." "But sometimes cyclists break rules & hit people!"

I’ve seen a few people commenting today that the idea of separating the MMR vaccine into three separate shots might be a good strategy to get anti-vax parents to vaccinate. Absolutely not. Here’s why. First, countering anti-vax misinformation is like playing whack a mole. You bat down one lie…

I understand that funding bodies want to go all in on AI as the shiny new innovation thing. But if all the grants start going to AI at the expense of everything else then the research sector is going to end up looking like a farm with dozens of threshers hacking away in a field with no wheat.

PSA: Summer is a tough time for the blood supply as regular donors are traveling and schools (where drives occur) are out. At the same time, accidents requiring massive transfusion are more common. Only 3% of the population donates yet any of us could be in need someday. Donate if you can!

HI HELLO. Mitch McConnell and Tom Kean got longer medical leaves (with literally zero transparency and fully funded healthcare) than I, and most women get after having a baby…including having a baby via major surgery 💁🏻‍♀️

More examples of victim blaming I’ve seen today: “Where has she been?” “The timing is suspicious” “But she had consensual sex with him before” “Why didn’t she call the cops?” STOP IT

Begging news outlets to stop illustrating deadly heat waves with happy beach fun 🏖️😎 and life-saving vaccines with terrifying needle assaults 💉😭. Especially on social media (where many/most people get their news) the photo is the most prominent part of the story; these choices undermine it completely

FFS I thought we'd moved past the ignorance of illustrating stories about deadly heatwaves with photos of people frolicking at the beach/in lakes/in fountains. Heatwaves are the deadliest agents of climate change. They kill nearly half a million people each year, and that's only going to increase.

🪼 Your tax dollars paid a scientist to squeeze jellyfish through cheesecloth. Osamu Shimomura processed tens of thousands on an NSF grant to understand why they glow. He found a protein that glowed green under UV light. Called it "green protein." Nobody cared. For decades.

This is awful to hear, describing how Sean Eddy (HMMER, infernal, pfam, rfam) has been defunded. The letter said his work "had been determined to be of absolutely no value to the US taxpayer, and therefore it was being specifically terminated," www.npr.org/2026/05/21/n...

Researchers say the Trump administration is finding new ways to punish science

Even with federal grants largely restored, scientists say the Trump administration is still preventing those funds from reaching them. The consequences, they say, are already becoming clear.

Late in the afternoon on Friday (yesterday), HHS/NIH did 2 things: 1) They RIFd more employees (despite the extreme staffing shortages). 2) They sent announcements to supervisors letting them know people in their chain of command will be moved to the career/policy “at will” status. 🧵1/3

Feeling overwhelmed with all of this. LISTEN. Another Louisiana resident (Marshawn is the only name we have) testifies against the state’s racial gerrymander, speaking truth to power up and down the hearing room and predicts how this story will end. Speak your truth, fight and believe.

Jeff Bezos has $222 billion. If he paid my wealth tax this year, we could fund insulin in America for everyone who needs it plus free school lunch for every kid in Texas—and have plenty of money left over. And Bezos would still have $215 billion dollars to spare.
