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

It is likely that the Court will back Trump, and say his (illegal) grant terminations are ok.

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?

Glad to see this, but I have another idea...Hear me out here...
Why doesn't NIH just reinstate the effing awards since they are ongoing and already made it successfully through a competitive process?
Seems like this would actually be "efficient" (and also fair and just)...
