LAST DAY TO TAKE ACTION: OMB’s proposed regulation shifts authority away from merit-based review systems by allowing political appointees to serve as final decision-makers in the grant approval process. Take action. Write a public comment by 11:59 PM: buff.ly/Mr96tW4
Protect the Peer Review Process: “OMB should preserve independent, merit-based peer review as the foundation of federal research funding decisions and ensure that proposal evaluation remains grounded in scientific expertise.”

The deadline to comment is tomorrow! OMB’s proposed Regulation for Federal Financial Assistance enables abrupt suspension or termination of federal funds for ongoing research projects. Act now by writing a public comment before Monday, July 13 at 11:59 PM ET: buff.ly/Mr96tW4
Leave Grant Administration in the Hands of Experts: “OMB should preserve flexibility in award structures, maintain safeguards against arbitrary termination of research awards, and ensure that any reforms support stable and predictable administration of federally funded research programs.”
