Scientists had to change more than 700 grant titles to receive NIH funding. Health disparities researchers fear what’s next
The titles of more than 700 multi-year NIH grants have been changed this year, according to an analysis by Jeremy Berg, a former agency official

Not that it matters, but my MOSAIC was scored a 14. Reviewed in study section w non-MOSAIC K99s. I'm to write another grant that may not be funded, that doesn't provide transition to faculty funds, instead of doing the work that was reviewed so highly? That's the best use of time & tax payer money?

So many important things are discussed at conferences. When international travel is dangerous & science is under threat & research funding is being slashed & we know how bad flying is for the climate & we have technology to make it happen, the fact that all conferences aren't hybrid is wild. 🧪

Just one example: In the past 2 weeks, NIH has terminated dozens of programs to support students pursuing scientific careers. These MARC or U-RISE (T34) grants provide rising undergraduates with opportunities and stipends to participate in science. Where are these programs? Not in the Ivy league:
