Astonishing. RFK Jr. adds 8 members to a 6 member FDA advisory panel. 6 of them were sellers of peptides, and the 7th a compounding pharmacist. In an 8-6 vote with all 8 votes coming from these new panel members, the panel approved 4 peptides against the objections of FDA scientists.

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-...

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. “Without these meetings happening, nothing can get funded.”

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.
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.

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 on—the spindle pole body—to the sculpture. Here it is close up, in sterling silver embedded in the bronze nuclear membrane. 🔬#SciArt
A dividing budding yeast cell in steel, bronze, and silver, with apatite gemstones for the chromosomes. The sculpture rests in my hand, a physical cutaway view with many cellular structures visible. 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.

An oldie from Inktober 2018: trilobyte
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
