Such a fine resource for the community! 👏👏🙏

Thank you, Anuj and Maureen!! I have been slow on social media recently... life is 🤯

How we’re rebuilding the Weizmann Institute — and our hopes for a better future Scientific research is at the heart of Israel’s success and has worldwide benefits. Our work will continue despite adversity.

I share Alon’s hope : "I look forward to the day when Israeli scientists can freely collaborate with scientists in Iran and do good for the region and for humanity. I wish the same for scientists in Gaza and throughout the Middle East." @WeizmannScience www.nature.com/articles/d41...

For #worm25, here are updated lists of 200+ researchers for the #Celegans community to easily follow:

C. elegans #1 (150 full) - go.bsky.app/HP1h3nW
C. elegans #2 (50+) - go.bsky.app/J7soTHG

Same :) Though I am kind of ok with NOT having jetlag from the 10 hr time difference :)

I am excited (as usual) about attending #Worm25. But I am also sad that so many friends and colleagues can't be there. Because you know....insane policies and war and such. Hoping the science will provide at least a temporary distraction from the unending chaos.

I think we just witnessed the first ever nematode ménage a trois! #worm25

@eyawolfson.bsky.social can tell you that looking at a full plate of C. afra will blow your mind 🤣🤣
Sad to have missed all the reactions!!!

Today! Correction- 1PM eastern not 12:30 🫣

You are correct, I copied the zoom invitation time, the session will start at 1 eastern, my apologies!!!

Sources of behavioral variability in C. elegans: Sex differences, individuality, and internal states Animal behavior varies across different timescales. This includes rapid shifts in behavior as animals transition between states and long-term changes …

How do different sources of variation, acting on distinct timescales, integrate to shape behavioral diversity?
It was a pleasure writing this review with Meital Oren-Suissa @meital.bsky.social and Steve Flavell.

Thank you! 😊

Thanks Surojit!

Apologies, I guess it’s my over sensitivity, as studies in worms are often dismissed as irrelevant… in any case you are right of course. interestingly there are reported sex differences in stress related disorders and if the NPY system is involved is yet to be proven…

Thank you!

Thank you so much Maureen!!! 🙏🙏

Neuromodulation, sex specific responses, peptides, oh my!

Thanks!

No need to whisper :) Indeed, the figure shows the worms :)
In mammals, NPY levels have been shown to differ between the sexes, making stress susceptibility potentially sexually dimorphic

Thanks Nitzan 🫶

Thanks Yoav! And in time for the thesis defense! 🎊

Modulation by NPY/NPF-like receptor underlies experience-dependent, sexually dimorphic learning - Nature Communications Experience-dependent decision-making is vital for survival. Here, authors uncover how the neuromodulator npr-5 regulates sex- and state-specific learning in C. elegans, shaping behavioral responses.

After a long wait, our paper is out! We show that differences in learning between the sexes are modulated by the NPY receptor, which gates sensory perception. Great work by PhD student, soon to be Dr, Sonu Kurien

How curiosity-driven research in a worm won four Nobel Prizes Discover the significance of C. elegans in biological research, from Nobel Prize-winning discoveries to insights into gene expression control.

Co-wrote w/ Rohini this hopefully easily understandable article @thehindu.com on curiosity driven research w/ the worm, its many contributions to scientific advances, including several Nobels.
