Astrocytes are where it is at!

Sir Ian McKellen performing a monologue from Shakespeare’s Sir Thomas More on the Stephen Colbert show. Never have I heard this monologue performed with such a keen sense of prescience. Nor have I ever been in this exact historical moment.TY Sir Ian, for reaching us once again. #Pinks #ProudBlue

New preprint from the lab looking at the role of astrocytes in the nucleus accumbens core in incentive value-driven actions: www.biorxiv.org/content/10.6...

Happy 2026 everyone! Here's a nice write up of our recent work published in Neuropsychopharmacology, on the balance of habits and goal-directed actions in compulsive disorders: lnkd.in/g84fYnD5

I wish I was as busy as I was the first time I felt like I was busy.

Got an invitation to provide an article for a journal called "Nature, Cell, and Science" and was wondering if it was predatory. Google gave me this reddit thread, funny: www.reddit.com/r/labrats/co...

First alcohol lab paper out today! Neurotoxic effects of chronic ethanol on cholinergic interneurons in the dorsomedial striatum. doi.org/10.1016/j.ne... Many thanks to all contributors!

rdcu.be/eIyQB Now published in Neuropsychopharmacology, here we mimicked the striatal neuroinflammation seen in the brains of individuals with compulsive disorders and found that this facilitated goal-directed action, whereas activating the Gi pathway in astrocytes prevented it

Latest lab preprint! Astrocytes are a brain cell type vulnerable to the effects of stress and the development of psychiatric-like phenotypes in animals, yet how this translates to humans is unclear... so we dived in: www.biorxiv.org/content/10.1...

Fantastic review of #SexxAndImmunity! @soniasharma.bsky.social www.science.org/doi/10.1126/...

Position open for a neuroimaging focused postdoc to come work with us in Sydney Feel free to get in touch for a chat if you have any questions about it :) usyd.wd105.myworkdayjobs.com/en-GB/USYD_E...

New preprint from the lab, produced in collaboration with Simon Killcross' lab: Modelling compulsive actions in rats and mice: The back-translation of value-modulated attentional capture from humans to rodents doi.org/10.31234/osf... I will be presenting some of this work at Pavlovian next week!

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. doi.org/10.1101/2025...

New paper out! Here we show that attentional biases induced by reward history depend on awareness of such reward history (w/ @jlupiane.bsky.social and @mavadillo.bsky.social). link.springer.com/article/10.3... 👇🧵

I would add to this that journals are increasingly asking more of reviewers (e.g. format reviews in a specific way, long consults on top of reviewing) which I understand the reasoning for, but it does increase burden, and increase difficulty to find reviewers. www.theguardian.com/science/2025...

Couldn't be more proud of these two who graduated today, Drs Abiero and Ganesan.

💥GIF THREAD ALERT – pleased to share our latest paper @sfnjournals.bsky.social in J Neurosci- an epic over 5 years in the making examining amygdala and prefrontal interactions with the medial OFC in risk/reward decisions by Nicole Jenni and Deb Bercovici www.jneurosci.org/content/45/1...

It's gonna be epic!

Don’t forget to submit your data blitz or poster abstracts for PAVLOVIAN in SYDNEY!🧪🧠 Due April 11th, including 5 x travel awards to help our buddies from the 🇺🇸 and elsewhere get to 🇦🇺 Our line up is 🔥 Check out our website, registration, and hotel block below 👇

Exciting new science from the lab led by @melcooperphd.bsky.social. More to come soon!

For those hurting after DP EOI outcomes today, courtesy of ChatGPT (I prompted with the first line, it will have to go over 2 posts as it's too long): Oh ARC, why won't you fund me? I’ve written papers, set them free, With research deep and insights bright, Yet still, no grant, no guiding light.

The ARC have tweeted that they will released Discovery Projects Expression of Interest outcomes tomorrow.

Diversity is our greatest asset, even if the government disagrees… They not like us! POC in STEM are here to stay. They tried to rig the game but you can’t fake influence! Mustard on the [Be][At] bro. Happy Black History Month!

🚨📃New Wassum Lab Paper📃🚨 Out today, @jackiegio.bsky.social discovered brain pathways that support agency and habit and how chronic stress disrupts them to rob of us our agency and cause us to form rigid habits 🧵👇 www.nature.com/articles/s41... Free full text: rdcu.be/eaxEv

I know everything is falling apart so this may not be the best time to post this, but know that we are watching on in horror in Australia and will do what we can to help. Anyway, Psy post wrote an article about our article: www.psypost.org/brain-inflam... www.sciencedirect.com/science/arti...

Happy to share the latest finding on anterior cingulate cortex (ACC) and information choices from @vgonzalez.bsky.social ! #neuroscience 1/n www.eneuro.org/content/earl...

Enjoyed the use of the word "bollocks"in the first paragraph 😆

In short, there are actual data showing that in extramural NIH grant competition, Black PIs have to work twice* as hard to be considered half** as good. DESPITE all of the NIH DEI efforts that were in place at the time. *much more than twice **about 60.5% of the success rate

#ARCschedule Feb25 Outcomes expected for Discovery Projects EOIs. Other events: 🔹Applications close for Discovery Indigenous 🔹Rejoinders for Industry Fellowships & Industrial Transformation Hubs & Centres 🔹Selection meeting for Laureate Fellowships Data ▶️ docs.google.com/spreadsheets...

New paper out in @currentbiology.bsky.social with the inestimable @kurtfraser.bsky.social and @janaklab.bsky.social. We think this work illuminates an important way the brain dynamically orchestrates motivation, and look forward to testing new hypotheses this inspires in disease models.

You can put people in jail for trying to discredit your research? 🤔🤣

....and @bita137.bsky.social to the rescue with the facts on why measuring estrous cycle isn't necessary 🤩

If your #NHMRC ideas grant was unsuccessful and you have a story to share about the impact of this on your #biomedicalresearch, career, team - get in touch. Federal DOH have asked #NARF to collect stories of impact of low funding. #SaveOzScience #DiscoveriesNeedDollars #EMCRs

Honoured that our work (now publish in Brain, Behavior, and Immunity) was highlighted in this post! Thank you Nicole, I will try and answer your questions in the thread below. 1/8

Very good, concise summary of the gut-brain axis of communication and interoception www.cell.com/current-biol... open-access

ARC says they’ll release the Discovery Projects 2025 outcomes tomorrow. Recently, outcomes announcements have tended to happen at/around 11am Canberra time. My bot will pick up the announcement in RMS’s database and post immediately. Good luck!

Editorial at The Lancet today on this matter www.thelancet.com/journals/lan...
