Kristin Rose Jutras 38m Devastated to share that my husband, @jutraslab.bsky.social, passed away. People are writing fake obituaries online/sharing on social media that Brandon died of Lyme disease. This is not true and is an affront to everything Brandon stood for as a scientist: the truth.

Quote from Paper “This trend raises questions about whether research papers can remain a reliable method for sharing scientific progress.”
Evan Spotte-Smith (they/them)@ewcss.info · 6mo agoThis piece is about CS conferences, but it speaks to a larger trend. What are we, as individual researchers and scholarly communities, doing to prevent epistemic poison? What can we do to preserve and maintain the quality of our knowledge in this era of bullshit and slop? ⚗️ 🧪 #SciComm #Ethics
The annual news blitz about danger this time year of Vibrio vulnificus is upon us. If you live in the Gulf or Atlantic areas, and particularly if you have liver disease, cancer, or immunosuppression, Vv is a danger. The disease is rare but death rates high, survivors have long hospitalizations 🧵
How to protect yourself from Vibrio vulnificus, the bacteria found in some coastal waters
States are warning beachgoers about a summertime surge in infections from a frightening, flesh-eating bacteria found in coastal waters.

“NIH will introduce a cap on allowable publication costs starting in Fiscal Year (FY) 2026, ensuring that publication fees remain reasonable across the research ecosystem. The policy aims to curb excessive APCs & ensure the broad dissemination of research findings w/o unnecessary financial barriers”

This is an event on Tuesday in the House of Representatives hosted by the minority Science committee, led by @lofgren.house.gov. Real question: why isn’t this being held in the evening and produced for TV and social media? There are production and storytelling resources in Congress.

Northwestern Basic Sciences@nu-bsa.bsky.social · last yr.Scientists led by @karlasatchell.bsky.social have discovered previously unknown molecular mechanisms that help a type of foodborne bacteria, Vibrio vulnificus, recognize host cells and initiate infection, according to a recent study in Science Advances. @jiexic.bsky.social tinyurl.com/mtu457fj

Delthia Ricks@dricks.bsky.social · last yr.After screening nearly 500 FDA approved compounds, researchers have settled on piperacillin as a good candidate for clearing the bacteria that cause Lyme disease. B. burgdoferi is known for lingering in some patients causing post-treatment Lyme disease syndrome, also called chronic Lyme 👇
To say it once more today: I think you'll be moved if you take 2 minutes to look through 269 institutions signed on here. Yes, still a few notable absences. (Where is Stanford?) But such an array of *presence.* Big and small. Public and private. World famous and barely known. Check them out.

It’s impossible to overstate how much damage Trump/Elon/Vought/RFKJ are doing to science in America. We need everyone who can to show up and demand action to save scientific research in this country. Scientists are trained to question everything which is why fascists always target them first.

Elon Musk said DOGE made a mistake by cutting USAID’s Ebola prevention but it had been “restored.” That’s not true, current and former officials told me and @johnphudson.bsky.social. “There have been no efforts to ‘turn on’” Ebola prevention, said Nidhi Bouri, who oversaw team until January.
Musk claims DOGE ‘restored’ Ebola prevention effort. Officials disagree.
USAID’s initiatives to fight Ebola and other diseases have been gutted, current and former agency officials said.
