It's one of those times of years to go a-RePORTERing, my friends. Select 9/1 or 9/15 in the Project Start Date field and put your favorite IC in the field for that.
As the NIH reaches the end of the federal fiscal year, they have to balance their budget. Meaning that in many cases they will pick up out-of-order grants to satisfy some goal or other. No doubt sometimes it is just making the dollars and cents add up by slotting in a few more R03 or R21 grants.
Maybe it is a chance for them to trigger on priorities that they have been letting simmer on the back burner or maybe it is a class of grants that has to wait until the end of the year for some reason. BigMechs seem to be funded during September in several of my favorite ICs.
I seem to notice SBIR/STTR grants (R41, R42, R43, R44 mechs) rolling out, which makes sense. The overall NIH has a certain percentage it has to meet in terms of SBIR awards and I assume this rolls downhill to the IC level. So this is part of the balancing of books for the final accounting.
The thing I was noticing this year is that the list of grant awards from my favorite ICs seems...interesting. To me anyway. And given when I tend to find interesting (i.e., the unusual) it would be no surprise if this was as feature not a bug. I.e, real.
Look at it this way. The unusual has the potential to be treated somewhat poorly by study sections or it wouldn't be an unusual application. If you subscribe to a view that study sections suffer from a certain conservatism (and I do subscribe) than it makes sense that the end of year pickups might be interesting due to them being unusual. Perhaps there are POs who likewise look at the list of near-misses and are attracted to the grant application that offers a little breath of fresh air. Perhaps it is because there are the odd RFA extras that can be squeezed under the budget line.
...or maybe I am extrapolating too far from very limited data.
