My dept. is hiring a microbiologist (broadly defined)! We are a deeply curious and friendly dept. with lots of enthusiasm for unusual systems and strengths in regeneration & dev bio, ecology & evolution, and circadian rhythms. I highly encourage anyone to apply: ukjobs.uky.edu/postings/600....

He was at Harvard Med and then Boston University, and published work on other cell types from the lung, but the cilia work was the highlight. There are 64 figures in that JCS paper! It's not clear who made the amazing illustration that we all use - nobody is credited in the paper, so perhaps him.

A new study in ants from @danielkronauer.bsky.social reveals a previously unknown mechanism that ensures that each olfactory neuron expresses only one odorant receptor, with broad implications for the study of gene regulation. #RockefellerScience

Canceled grants get the spotlight at a Capitol Hill 'science fair' On Tuesday, scientists held an event organized by House Democrats in which they stood in front of posters outlining their work — and the federal cuts that now threaten it.

The genomic DNA was sheared by their prep, before the density gradient. The pieces were small enough that they were either fully replicated or unreplicated. If it was the whole genome, the experiment gives the wrong answer because the genomes are replicating asynchronously and relatively slowly..

I was young, and Stahl already seemed to me an old man who had done something famous long ago. Really, he was only in his mid-50’s and Meselson-Stahl was 30 years before. I regret not asking him more about it then, and the famous necessary artifact that allowed them to get the right answer.

Franklin W. Stahl, 95, Dies; Helped Create a ‘Beautiful’ DNA Experiment

Frank Stahl was a visiting scientist in the lab next to where I was a grad student at MIT in the 1980's. He loved nothing more than doing experiments with phage lambda, staring at the plaques through a pair of magnifying goggles, thinking about recombination. www.nytimes.com/2025/07/07/s...

Good to see acknowledgment from industry about the importance of fundamental research funding. We need more industry leaders to step up to make this point to Congress. www.statnews.com/2025/06/27/b...

Thank you, Tim! The Last Class film about Robert Reich is playing in NYC throughout this week at the wonderful Quad Cinema Greenwich Village through Thursday, July 3. Tickets available now here: quadcinema.com/film/the-las...

Saw the new film by @elliotkirschner.bsky.social about Robert Reich’s last class taught at UC Berkeley. It’s a film about @rbreich.bsky.social’s remarkable life, but also about the power of teaching and the classroom. Check it out!

About the art of writing, but applies to doing science, too.

It was, but I don't think the Senate version of that part of the bill is out yet.

It could. I haven't seen that part of the reconciliation bill yet, but should be out soon.

🚨 New preprint!
Using U-ExM + in situ cryo-ET, we show how C2CD3 builds an in-to-out radial architecture connecting the distal centriole lumen to its appendages. Great collab with @cellarchlab.com @chgenoud.bsky.social @stearnslab.bsky.social 🙌. #TeamTomo #UExM

Woo! Very excited to share our collaborative work on the centriole's Luminal Distal Ring ⭕. This project started 13 years ago with @hugovdhoek.bsky.social & @stearnslab.bsky.social, and then beautifully came together with @computingcaitie.bsky.social & @centriolelab.bsky.social.

I heard this morning that my informatics colleague Dr. Atul Butte passed after a battle with cancer. He was a giant in the field & inspired many of us over his distinguished career. He was a passionate champion of the power of big data & his impact on our field is immeasurable. RIP Atul & thanks.

Richard L. Garwin, a Creator of the Hydrogen Bomb, Dies at 97

RIP Dick Garwin, who I had the pleasure of working alongside every summer for more than 20 years. A brilliant thinker and compassionate person, Dick is the perfect example of how high-level science advice has been critical to the success of the U.S. www.nytimes.com/2025/05/14/s...

New lab preprint! Unveiling the Molecular Architecture of T Cells and Immune Synapses with Cryo-Expansion Microscopy (Cryo-ExM). A fantastic collaboration with Dr. Benita Wolf. Congratulations to all authors, especially Florent Lemaitre, for leading this amazing work! www.biorxiv.org/content/10.1...

Itai and I, along with Kelsey, have been doing these sessions with postdocs across NYC. Great fun and much science buddy interaction!

Join us at the New York Genome Center on June 2 for the final meeting before we take a summer hiatus.
