Finally, I want to inform readers that my lab has been at the forefront for >15 years on understanding how these bacteria cause disease. However, we are struggling because, as a Northwestern Faculty member, my grants to study these infections have been frozen since March. Please Support Science!

Vibrio vulnificus is also the leading cause of seafood-borne death. I love oysters...I recommend po' boys with fried oysters, grilled, and stews. But always cooked, especially in the warm months of the year. Shrimp and other seafood also can be sources of infection. journals.lww.com/ajg/fulltext...

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.

Science 🧪 fair of knowledge lost due to grant terminations. Why isn’t this being live-streamed? How do we - the people - get to watch?

RFK Jr's "MAHA" report is filled with references to studies that literally do not exist, or that completely misinterpret the studies' findings.

“We did not publish a paper.. on this topic with that co-author group, or with that title,” says one cited researcher.

The MAHA Report Cites Studies That Don’t Exist
The Trump administration’s “Make America Healthy Again” report misinterprets some studies and cites others that don’t exist, according to the listed authors.

Great new study by my excellent colleague @jutraslab.bsky.social on treatments for Luke’s disease

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 👇
Antibiotic Candidate for Lyme Disease Boosts Hope for Custom Approach
Researchers also put forth one explanation for chronic symptoms after treatment

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.

Now it's nearly 270 university presidents who have signed onto this "unprecedented government overreach" public letter. It was less than 180 this morning.

Graduate student Jiexi Chen presented today in the emerging scientist session #ASBMB25 on her new paper on toxin binding N-glycans. She did a great job!!

Taking a break from the news in Bsky. Happy to share amazing study by student Jiexi Chen on Vibrio vulnificus MARTX toxin engagement of N-glycans and receptor L1CAM. First study on this toxin binding to cell surfaces. #vibrio #microsky #toxins www.science.org/doi/10.1126/...
Vibrio MARTX toxin binding of biantennary N-glycans at host cell surfaces
The large pore-forming toxin MARTX with broad tissue tropism binds the essential unit of N-glycans on eukaryotic cell membranes.

Was great to participate in this project designed to test robustness of AI ligand prediction but had a side benefit of crowd-sourced discovery of a SARS-CoV-2 helicase inhibitor

...and kudo to Karina Machado and @dkoes.compstruct.org for their winning predictions and to @karlasatchell.bsky.social for the unwinding assays!

The CACHE #2 preprint is now online: bit.ly/3DyCmHN Active learning and fragment growing delivered confirmed hits. A citizen scientist using the Fold-it gaming interface designed the top compound! Kudos to Sasha and Madhushika @thesgc.bsky.social at the bench. @conscience-network.bsky.social

Hi @schakowsky.house.gov The weather is supposed to be nice for @standupforscience.bsky.social Rally for Science on the National mall. I am coming from Evanston, hope to see my rep there too!!

They can use AI bots on their side to save time/cost to replace editors, and now trying to normalize this behavior to get reviewers to volunteer more often so they can grow revenue.
karlasatchell.bsky.social
Nature is responding to a critical flaw in their business model, they need to grow revenue to keep billionaire investors on board, but depend on volunteer peer reviewers.
