From Scienceinsider:
The National Institutes of Health will dedicate most of its $8.2 billion for research from the economic stimulus bill to funding grant applications it has already received and to supplementing existing grants. A smaller amount, on the order of $100 million to $200 million, will go to new grant applications it receives in the coming months.
Also mentioned are a new set of targetted challenge grants which will be for as much as $500K for two years.
It suggests to me that NIH is managing the new dollars in anticipation that it’s overall base budget will not change so much going forward.
