NIH Funding Is at a Standstill. This Professor Is Tracking the Delays. More than half of the NIH grant-review meetings that were supposed to take place this year have been cancelled, she says. β€œWithout these meetings happening, nothing can get funded.”

NIH funding is frozen. @annikabarber.bsky.social is keeping score: 50%+ of study sections planned for this year (77/148) have been cancelled.

I talked to Dr. Barber about why these delays are disastrous, and why scientists should be pooling info and speaking up: www.chronicle.com/article/nih-...

This is absolutely correct. Convo I had last week that is part of why I resigned:

Much more senior leader: no, we still can't post FRNs.

Me: Doesn't that mean we can't proceed?

MMSL: correct

Me: doesn't that mean we're not in compliance with the TROs?

MMSL: ...um...yea, in a way...

Update: They were removed from our reviewer assignments completely. I'm so sorry to all those graduate students. 

Anonymous to protect the identity of the NIH employee I spoke to...I am on study section next month to discuss F awards. We were just instructed to put the F31-Diversity applications on the bottom of our priority list for review because there is a chance we may not be able to review them. My heart is breaking for the grad students and their mentors that put so much work into these just for them to be disqualified and thrown out.

Just in case you thought that removing DEI criteria would mean that everyone is competing equally: NIH is removing grad students from underrepresented backgrounds from the applicant pool altogether. Their applications will not be considered. Other students, not from these backgrounds, will be.

Closeup of the sculpture, centered on the spindle pole body, a tiny structure looking like a stack of pancakes from the side, embedded in the long curved nuclear membrane, tethering the spindle (a splayed bundle of silver branches each terminating in a jewel chromosome). The spindle structure is polished silver, lodged in the  polished bronze of the membranes and surrounded by bronze endoplasmic reticulum, mitochondria, and other structures.

A favorite commission this year, a dividing cell with an extra detail. Colleagues of a retiring researcher commissioned me to add the specific structure she worked onβ€”the spindle pole bodyβ€”to the sculpture. Here it is close up, in sterling silver embedded in the bronze nuclear membrane. πŸ”¬#SciArt

To quote @denisduboule.bsky.social , IMHO one of the best definition of curiosity-driven basic research & serendipity

"going off to look for mushrooms and coming back with blueberries. If you are payed to find the mushrooms, you won't come back with the blueberries. You will come back with nothing.

Three panel black and white comic. Panel 1. A smiling eel-like primitive fish shows off it's new iPhone in front of it to two trilobites. Fish dialogue: check out my new phone! It's got 16 gigabytes it can hold! Trilobite dialogue: oh yeah? How many trilobites can it hold? Panel 2: the fish looks on, concerned, as the two trilobites crawl onto the phone and others join. Panel 3: the fish looks upset, its phone is buried in several trilobites. Fish dialogue: please stop
