Remember when NIH Director Jay Bhattacharya said there were no banned words and NIH Program Officers were making them up? Here’s the proof he lied: apnews.com/article/cali... I know, Jay Bhattacharya lying is not news. But it’s still really validating to have the admission.

The ADA called the cops on attendees--one of them a former ADA president--for distributing reprints of an article pulblished in the ADA's flagship journal. "Failing to meet the moment" is starting to feel like the understatement of the century when it comes scientific organizations in the US.

Shame on the American Diabetes Association- ejecting scientists from the meeting for distributing copies of an editorial critical of NIH funding cuts. Kudos to these scientists for standing up for science and resisting censorship 👏🏻👏🏻👏🏻 Now to go check the IDweek code of conduct page…

Big congratulations to our winners: Smilla-Maria Koy (1st), Chandrama Ghosh (2nd), and Anthony Rabaté (3rd)! Check out their breath-taking micrographs and the rest of the Top 15 entries in the stunning poster attached. The future of cilia research looks beautiful. 📸 #Cilia2027

Holden Thorp is an institutionalist. He's been a university chancellor, provost, now EiC of Science. When institutionalists pull the fire alarm, we listen, because the call to action he issued this week exposes the dire nature of the threat we are facing. 1/ www.science.org/doi/10.1126/...

White House seeks to tighten political oversight of grantmaking

Sweeping proposed rule, now open for comments, would also restrict foreign collaborations and remove federal funding for open-access fees

It’s truly astonishing to see how comprehensively the US government is tearing down every part of the system that has made it up until now a world-leading power in science, research, and technological development. The entire world will suffer from this wanton destruction.

I came here in 1975. I'm a Nobel Prize-winning scientist born in Germany during WWII, came here in 1975 thinking there was no way fascism could take hold in this country. I was wrong. I don't not want to be book-ended by two fascist regimes. We will stand up and set things right.

Choice words from Dr. Szostak here. And while I am no Nobel Prize-winning scientist, I identify with the same quandary as an immigrant, moving here in 2009 and (proudly) becoming a citizen in 2023. I, too, don't recognize that country anymore 😢🇺🇸🧳🛫. newsletter.ofthebrave.org/p/im-a-nobel...

How do cells keep their cilia “clean” and functional? Our new study uncovers a conserved mechanism for retrieving polyubiquitinated proteins from #cilia – a process essential for cellular signaling and health. #cellbiology #ciliopathy #ubiquitin #IFT 🧵👇 1/n

A conserved mechanism for the retrieval of polyubiquitinated proteins from cilia

The temporospatial distribution of proteins within cilia is regulated by intraflagellar transport (IFT), wherein molecular trains shuttle between the cell body and cilium. Defects in this process impair various signal-transduction pathways and cause ciliopathies. Although K63-linked ubiquitination appears to trigger protein export from cilia, the mechanisms coupling polyubiquitinated proteins to IFT remain unclear. Using a multidisciplinary approach, we demonstrate that a complex of CFAP36, a conserved ciliary protein of previously unknown function, and ARL3, a GTPase involved in ciliary import, binds polyubiquitinated proteins and links them to retrograde IFT trains. CFAP36 uses a coincidence detection mechanism to simultaneously bind two IFT subunits accessible only in retrograde trains. Depleting CFAP36 accumulates K63-linked ubiquitin in cilia and disrupts Hedgehog signaling, a pathway reliant on the retrieval of ubiquitinated receptors. These findings advance our understanding of ubiquitin-mediated protein transport and ciliary homeostasis, and demonstrate how structural changes in IFT trains achieve cargo selectivity. ### Competing Interest Statement The authors have declared no competing interest.
