In case you've ever wondered, I talked with @amjeve.bsky.social about science, myself, and the future of #DevBio as part of the Pathway to Independence Fellowship @biologists.bsky.social 🧪 journals.biologists.com/dev/article/...

Congratulations to Dr. Matt Wirick for successfully defending his PhD on the role of daf-16/FOXO in regulating stage-specific seam cell fate in the dauer life history of C. elegans!

Hi! Can you please add me to the science feed? My ORCiD is orcid.org/0000-0001-66... and my website is karplab.org. I’m embarrassed that I didn’t realize until now I needed to make this request. Thanks for your time!

Well, none of us may ever get funded again but in the meantime, here's some new science!

Led by recent PhD Anjali Pandey w/ex-UG Maya Katz. Here we identify an asymmetric molecular mechanism that underlies symmetric context-dependent sensory plasticity in the AWC olfactory neuron pair in C. elegans

This morning, NASA released the #VoyagerDeclaration. This afternoon, NIH #BethesdaDeclaration signers met w/ Jay Bhattacharya. Earlier, EPA staff were terminated for their act of resistance.

I made this in solidarity. @altnih4science.bsky.social @altnasa.bsky.social @alt-epa-workers.bsky.social

I’m pleased to share the latest preprint from the Iyer Lab! 🎉
We uncover a novel role for dynamin in regulating spindle pole assembly and PLK-1 localization during late mitosis in C. elegans embryos.

Over 2,000 senior staff set to leave NASA under agency push The losses could endanger the administration’s plans for landing astronauts on the moon and Mars.

THIS IS CATASTROPHIC FOR SPACE SCIENCE AND ASTROPHYSICS ...

GLOBALLY CATASTROPHIC, NOT JUST FOR AMERICANS 🔭🧪

Every time I see conservative fearmongering about how dangerous the NYC subway is, I feel the need to defend it. I grew up in Ohio. It’s cars that are dangerous. It’s car accidents that are terrifyingly common. I’m not being dramatic when I say the subway is one of the best parts of my life now.

Something joyful after the worm meeting. Karp lab F2s came to visit! Three of my students are parents, one with twins :)

Congrats to the winners of the #Worm25 poster competition!

Thanks to all students who entered (285) — such great research!

Thanks to all poster judge volunteers who judged presenters (220 postdocs and faculty!)

Given >1200 attendees, that’s a high % who participated in this competition!

As it’s my first time joining Worm Meeting, I was excited to participate in Worm Art show as well.
This year’s topic is resilience. In times of scarcity, worms gather holding one another to reach new grounds. Alone - they are fragile, together - they rise. Even the sky yields in unity. #worm25

Wanted to post a video we accidentally forgot to show at the Worm art show #worm25 from the Van Buskirk lab @cswormlab.bsky.social @baristursun.bsky.social

Hope you all enjoy!

A group of 10 people sitting at a restaurant with menus, smiling for the camera. Current and former Greenwald lab members.

Five people sitting at a wooden table, outdoor restaurant seating, smiling for the camera. Current and former Ambros lab members.

Ten people standing in front of the Mondavi Center, smiling for the camera. Victor Ambros plus current and former lab members.

So much great science at #worm25. Best of all was being with the C. elegans community, including hanging out with current and former members of the Greenwald and Ambros labs, where I was lucky enough to get my training. I’m so grateful for you all.

Thank you both for all of your work!

Congratulations to all the #worm25 Poster Award Winners and Honorable Mentions!

Go worms! #worm25

I always love #worm25 CGC updates! But spread this impt reminder (*especially* in this funding climate): CREDIT THE CGC on papers!🪱

Include this to keep the CGC around forever: "Some strains were provided by the CGC, which is funded by NIH Office of Research Infrastructure Programs (P40 OD010440)."

Hey everyone!
Come check out my talk this Sunday in the Development session. I will be presenting as Talk #38, right after the coffee break at 10:33 AM.
So bring your coffee and your curiosity!

Hi #ASMicrobe folks: my students are presenting posters today:

AES09 #791: Sarah Pasqualetti describes plastic degrading microbes isolated from fish guts.

HMB 911: Sihan Bu describes changing microbiomes in huge eco/evo expt

HMB 949: Carol Vieira da Silva describes Aeromonas SLP on OMV

A notebook that says Differentiation and has a picture of cilia on it

Are you at #2025ICDB @socdevbio.bsky.social @isdb.bsky.social? Do you want a free pretty notebook? Please come find me and say hi! I have a bag full of them! It features a gorgeous image from a cilia paper from @jbwallingford.bsky.social’s lab! doi.org/10.1016/pj.d...

Judge rules against NIH grant cuts — and calls them discriminatory The decision means that the US biomedical agency has to restore funding to hundreds of research projects, but the government will likely appeal.

After ruling the NIH grant cuts were illegal yesterday, Judge Young, a Reagan appointee on the bench since 1985, ended the hearing with a blistering 15-minute speech.

I've cleaned up my notes — here are his remarks in full. 🧵

If §122.2 applied it would mean a USDA license would be required to move Caenorhabditis elegans across state lines! And I’ve never heard of such a thing

Anyway here’s USDA’s own page:

Congratulations! I look forward to reading it.
