Our latest efforts to understand Enterococcal wound infection. In long-term collaboration with @gthibault.bsky.social, we discovered how E. faecalis makes extracellular ROS - via EET!⚡️Which in turn dysregulates host UPR to delay wound healing. Led by @aarontan.bsky.social - his videos below are 🤩!
gthibault.bsky.social
📢 Our new preprint is out! We show how the common gut bacterium 𝘌. 𝘧𝘢𝘦𝘤𝘢𝘭𝘪𝘴 stops wound healing. It uses a metabolic pathway, extracellular electron transport (EET), to stress host cells, halting their migration. Watch WT bacteria (orange) stop the cells while the mutant (blue) doesn't!

I am really excited to see this article on basic experimental design principles published. Definitely will be mandatory reading for incoming graduate students in my lab. Maggie Wagner who led this article did an amazing job with the illustrations of basic principles www.nature.com/articles/s41...

Super excited to share our paper online 🚨today🚨 in Cell Host & Microbe‬! Xiaomei Ren @xiaomeiren.bsky.social and Mason Clark @rmasonclark.bsky.social‬ co-led discovery of ecological factors for Acinetobacter baumannii carriage in the gut, a reservoir for pathogen spread. 🎉

Amino acid competition shapes A. baumannii gut carriage

Acinetobacter baumannii uses ornithine to compete w/ microbiota & persist in gut. Amino acid supplementation & differences in diet promote A. baumannii gut colonization in mice & humans

Please contact Congress ASAP to raise awareness of this accounting plan.

Aiee. We have also heard lots of rumors about this “multi-year funding” issue, and @baldwin.senate.gov, @drugmonkey.bsky.social, and @jeremymberg.bsky.social have all talked about it.

This is very bad. “One weird budget trick” that will cut the number of grants this year in half! 🧪

New, from an anonymous NIH insider: Trump is being pushed to spend more NIH money. The White House is ordering NIH to do multi-year budgets for awards. This budget trick means fewer awards, fewer labs funded, and lower paylines for researchers. 🧵

New preprint! We characterise the small, regulatory RNA Arp which controls DNA uptake and twitching motilty in A. baumannii. Led by our Dr Fergal Hamrock @hamrockfergal.bsky.social and in collaboration with @westermannlab.bsky.social and Mike Gebhardt's lab!

New @nejm.org report shows a rapid rise in tetM-carrying Neisseria gonorrhoeae strains in the U.S. jumping from <10% in 2020 to >30% by early 2024.
Why? Likely linked to our increased use of doxycycline both for STI treatment and DoxyPEP.

🍂 👿 Brown University has not Received NIH Grant Payments Since April
🧪
"Department of Health and Human Services (HHS) also told NIH to not communicate with the schools about 'whether or why the funds are frozen' "

Email from Brown admin: government stopped payment on existing NIH grants as of April 3; in three months since, the gov't has cumulatively withheld $45 million in NIH grant reimbursements.

Whatever injunctions, court orders, etc. may exist, no resumption of payments... and no explanation either.

Important story about OMB's plans with regard to appropriated funds. This is a big deal, both practically and constitutionally.

NEW at grant-watch.us: Emma Mairson and Marian Jarlenski report on funding freezes at Brown, Columbia, Cornell, and Northwestern, that have received zero payments for #NIH grants since the start of April: grant-watch.us/posts/trends...
Two line graphs show NIH Outlays for Grants at Brown University. The left graph, "Outlay per month (USD)," shows monthly outlays from October (P01-P02) to June (P09) for fiscal years 2022, 2023, 2024, and 2025. The 2025 line (black) shows outlays around $15,000,000 from October 2024 to March 2025, then drops sharply to $0 in April 2025 and remains at $0 for May and June. Lines for previous fiscal years remain above $10,000,000 throughout the period. The right graph, "Percent of grants without an outlay," shows the percentage of grants without monthly outlays over the same period. The 2025 line (black) shows percentages below 10% until March 2025, then spikes to 100% in April 2025 and remains at 100% for May and June. Lines for previous fiscal years remain below 20%. Two line graphs show NIH Outlays for Grants at Columbia University. The left graph, "Outlay per month (USD)," shows monthly outlays from October (P01-P02) to June (P09) for fiscal years 2022, 2023, 2024, and 2025. The 2025 line (black) shows outlays between $40,000,000 and $60,000,000 from October 2024 to March 2025, then drops sharply to approximately $20,000,000 in April 2025 and to $0 in May and June. Lines for previous fiscal years fluctuate but remain generally above $25,000,000. The right graph, "Percent of grants without an outlay," shows the percentage of grants without monthly outlays over the same period. The 2025 line (black) shows percentages below 20% until March 2025, then spikes to 100% in April 2025 and remains at 100% for May and June. Lines for previous fiscal years remain mostly below 20%.

Lines for previous fiscal years show some variability but generally stay above $0, with some dips. The right graph, "Percent of grants without an outlay," shows the percentage of grants without monthly outlays over the same period. The 2025 line (black) shows percentages below 20% until March 2025, then spikes to 100% in April 2025 and remains at 100% for May and June. Lines for previous fiscal years show more variability than Harvard and Northwestern, with some spikes, as well, but returning to normal levels after.

The left graph, "Outlay per month (USD)," shows monthly outlays from October (P01-P02) to June (P09) for fiscal years 2022, 2023, 2024, and 2025.
