Congress toyed with the idea of explicitly prohibiting multi-year funding of NIH grants - which severely cut down the number of awards last year - but in the end, it didn't go through. Expect paylines to be only moderately better this year.

Some funding good news for a change (from AAAS policy alert)
The House and Senate released a final version of the National Defense Authorization Act. Of importance to the research community, the bill prohibits the DOD from imposing a 15% cap on indirect costs to institutions of higher education.

I got a similar message. My study section is being rescheduled for 2 partial days in January. Only 1/3 of grants will be discussed.
Just got an email from my SRO for the study section that was missed in October. Good news is that they are trying to reschedule ASAP (Dec/Jan). The bad news is that CSR is mandating that only the the top third (not half) of applications will get discussed for the next 2 rounds.

Is there a competition going on about who is going to screw science the most?
“The prohibited activities would include joint research, co-authorship on papers, and advising a foreign graduate student or postdoctoral fellow. The language is retroactive, meaning any interactions during the previous 5 years could make a scientist ineligible for future federal funding.”
