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.

Dr Kamar Ameen-Ali - Blog – Does the research funding process need reforming? Dr Kamar Ameen-Ali questions the fairness of funding processes and explores alternatives that could better support innovation and equity in research.

The research funding process in #academia is highly subjective, decisions are vulnerable to bias, and the process may be actively encouraging bad practice.

In this @dementiaresearcher.bsky.social blog, I explain why it needs reforming. ⬇️

And a pleasant #fluoresencefriday surprise too. Makes all those hours on the confocal worthwhile!

Huge thanks to the funders @fightforsight.bsky.social for organising an amazing day for #ECR #networking!

Image of human stem cell derived retinal ganglion cells in culture. Green = beta-3-tubulin, neural marker Magenta = gamma synuclein Blue = nuclei

Beyond chuffed to have received “Best Image” at #F4SECR2025 today, for this image. This is one of our batches of patient-derived retinal ganglion cells. A great #ECR #neuroscience day, with amazing advice for #PPI to broaden the horizons of our research - and apply it to the people it benefits! 🔬🧫👨‍🔬

Small things really do matter in type 1 diabetes. Exciting work from the Exeter SMF Grand Challenge team provides important insights into why #T1D in children may differ from T1D in adults. Important implications for screening strategies and future treatments. Check out our new bioRxiv paper 👇

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.

Seeing the world through the eyes of cultured cells The metabolic environment experienced by cultured cells often differs from physiological conditions. Here, we highlight the effects that the microenvironment can have on cultured cell behavior and advocate for researchers to re-evaluate culture practices…

Stem cell-derived retinal ganglion cells. Green = B-3-tubulin, red + blue = nuclear markers. Low seeding density to examine networking capacity - look at the size of those neurites! We aren’t yet sure what the green speckles (varicosities?) in the neurites are - questions, questions. Taken at 10X magnification.

Happy #FluorescenceFriday! Here’s one of our stem cell-derived retinal ganglion cells. Low seeding density to assay their networking potential, look at the length of those neurites!
Not yet sure what the varicosities in the neurites contain…🤓🧐🔬🧫
