With all the ups and downs in 2025 and so much uncertainty, I hesitated to share. In light of the government reopening today, I still want to share some outdated news: I was awarded my first R01 grant! Regardless of what will be the future looks like, the receipt of NoA alone is worth celebrating!😎

Hurricane Evacuation Patterns Differ Based on Where the Storm Hits
People in coastal areas with frequent hurricane exposure are more likely to travel out of harm’s way compared to people in inland areas who are more likely to stay put.

New research on Hurricane evacuation!
Through a huge multidisciplinary collaboration effort, we showed that fine particulate matter (PM2.5) exposure raises Lewy body dementia risk. Mechanistically, we found that PM2.5 exposure led to brain atrophy in mice. Lewy body dementia promotion by air pollutants www.science.org/doi/10.1126/...
Lewy body dementia promotion by air pollutants
Evidence links air pollution to dementia, yet its role in Lewy body dementia (LBD) remains unclear. In this work, we showed in a cohort of 56.5 million individuals across the United States that fine p...

Observing the #extremeheat events in NYC and across the US this week, I’m reminded you that the latest #NIH #grants cuts killed the project I led to improve heat-warning systems, now everyone’s more exposed to severe heat, and everyone's #health is paying the price. Tell your officials this matters.

Of course🙂
Well, that was short-lived: NIH staff received instructions to HOLD funds to Columbia again.
The email was one line: "Columbia University and Columbia University at Morningside are back on hold."

Is this real?
DOGE is now reviewing every NIH grant that goes out, I reported last week.
That review is AI-driven and is screening for DEI, trans health, China, vaccine hesitancy, and the institutions to whom Trump has blocked funding, @hannahnatanson.bsky.social reports.
