Bluesky is the new science Twitter, new study by @whysharksmatter.bsky.social and Julia Wester concludes!

"Results show that for every reported professional benefit that scientists once gained from Twitter, scientists can now gain that benefit more effectively on Bluesky than on Twitter."

Scientists no Longer Find Twitter Professionally Useful, and have Switched to Bluesky

Synopsis. Social media has become widely used by the scientific community for a variety of professional uses, including networking and public outreach. For

Statistics say that Americans are disconnected—but Minnesota’s response to ICE shows how many neighbors care enough about one another to “stand up to armed federal agents, and even risk death,” @julieebeck.bsky.social argues.

Americans Love Their Neighbors

Statistics say this is a time of disconnection. Minnesota’s response to ICE shows otherwise.

The FBI was able to access Washington Post reporter Hannah Natanson's Signal messages because she used Signal on her work laptop. The laptop accepted Touch ID for authentication, meaning the agents were allowed to require her to unlock it. storage.courtlistener.com/recap/gov.us...

“Measles in South Carolina has spread to at least 789 people, surpassing the 2025 West Texas outbreak that sickened 762 people and killed two young girls.

The majority of cases remain centered in Spartanburg County, mostly among people who were either unvaccinated or didn't know their status”

Alex Pretti was a colleague at the VA. We hired him to recruit for our trial. He became an ICU nurse- I lover working with him. He was a good kind person who lived to help and these fuckers executed him.

What should success look like here?
And how should effectiveness and impact be measured?

Hi from your friendly gun violence researcher!

Want to know one thing we did differently? Since 2022, we have approached firearm homicide (the most common type) not just as a crime problem, but also using all the tools of public health - education, environment change, etc.

The Washington Post @washingtonpost.com · 24d

The U.S. remains in a multiyear trend of falling rates of homicides and other crimes in cities nationwide, according to a Post analysis. Rates of aggravated assault and burglary hit their lowest point last year since the start of the pandemic in 2020. https://wapo.st/4qE0b4j

The Sciencewashing of Everyday Life

US citizen says he felt fear, shame and desperation a day after ICE officers broke down his door with guns drawn, handcuffed him and dragged him into the snow wearing half-dressed.
He was later returned home without explanation or apology, he said.
