Astrocytes orchestrate oxytocin’s social effects in mice The cells amplify oxytocin—and may be responsible for sex differences in social behavior, two preprints find.

“Astrocytes in the lateral septum may explain, or be at the basis of, the sex differences we observe in terms of social fear.” –Alexandre Charlet.

I defended my PhD 10 years ago today. That was the least remarkable thing that happened that day. Sharing something I wrote about it last year. Since then "the horrors persist but so do we." And with dignity.

Thanks @gliameeting.bsky.social for selecting me. It was a very exciting meeting!

We look forward to seeing you Tomorrow Nov 26 at 2PM for the 2nd IGN SYMPOSIUM. A time for Glia related Science, with open and live discussion with the Italian glia community. See you Tomorrow!!!

Good work takes time sometimes and @brianjjoseph.bsky.social runs long marathons! Glad to be part of such an interesting study, great team work 💪🏼

Selective RNA sequestration in biomolecular condensates directs cell fate transitions - Nature Biotechnology Stem cell differentiation is controlled by manipulating RNA condensates.

1/ Excited to share our new study with @brumbaugh-lab.bsky.social, out in @natbiotech.nature.com! P-bodies selectively sequester RNAs encoding cell fate regulators, often from the preceding developmental stage. Releasing these RNAs can drive changes in cell identity. 🧵 www.nature.com/articles/s41...

I am proud to share our work on X-linked Dystonia-Parkinsonism — a rare neurodegenerative movement disorder driven by a SINE-VNTR-Alu retrotransposon insertion in the TAF1 gene.

Read our two companion papers:

Proud to present our new paper in @natmetabolism.nature.com

The Neurolipid Atlas: a lipidomics resource for neurodegenerative diseases
lnkd.in/eVzFrmUY

Check out our open-access platform chock-full with iPSC- and 🧠 lipidomics data (www.neurolipidatlas.com).

Now on bioRxiv! Astrocytes in one brain region (cyan) communicate in expansive networks (magenta). Through tool development, tissue clearing, and many hours on our @zeiss-microscopy.bsky.social Z1, we now know these networks are repeatable across mice, plastic, and specific.

Thanks to Dave and Joseph for the nice coverage!

The Coming Out of a Transgender Scientist "I know that I am making the right decision because whenever I think about changing my gender role, I am flooded with feelings of relief."

We're disappointed to see Ben Barres's powerful book "The Autobiography of a Transgender Scientist" among the ~400 titles removed from the Naval Academy Library. Needless to say, we're proud to have published his book and will keep it — and his memory — alive.

As an international scholar, I’m learning to speak up—accent and all “My ideas matter more than how I sound,” this postdoc writes

"I stopped seeing my accent as a problem and started to embrace it."

This week's #ScienceWorkingLife: scim.ag/3VpsO7u

@amyxguo.bsky.social from New York, @liddelowsa.bsky.social lab, has characterized the LCN2 tdTomato mice that label reactive #astrocytes & reactive #endothelial cells. First timer at the #GRCGlia2025, she's done great asking good questions. Definitely one to follow 🔬🧬🍅✨ med.nyu.edu/faculty/shan...

Varicose-projection astrocytes: a reactive phenotype associated with neuropathology Glial cells are fundamental for the pathophysiology of all neurological disorders. Astrocytes, the primary homeostatic cells of the central nervous system (CNS), exhibit species-specific characteristi...

🚨The first #preprint of the #FalconeLab is OUT!🥹🚨

We found that varicose-projection astrocytes are not a physiological type of #astrocytes but they are rather associated with neuropathology.

Fresh off the press! We found that degeneration in one retina causes astrocytes to respond retinotopically across *both* hemispheres of the brain. Perhaps astrocytes across the CNS are able to coordinate their responses more than we anticipated... www.pnas.org/doi/10.1073/...
