🎉 Our review on how adult neural stem cells are kept quiescent in the zebrafish telencephalon is finally out in GLIA! We summarize established mechanisms and propose an integrative hypothesis. doi.org/10.1002/glia... #Zebrafish #NeuralStemCells #Neuroscience

Molecular Control of Neural Stem Cell Quiescence in the Adult Zebrafish Telencephalon: Established Mechanisms and an Integrative Hypothesis
Adult zebrafish radial glia quiescence is controlled by at least four mechanisms: Notch3, BMP-Id1, Nr2f1b and Midkine-a. We propose these act as partially redundant inputs, biased along the anter...

It’s completely wrong to claim the Iranian people have only two choices: a far-right pro-U.S. regime or an Islamic dictatorship. That’s a false narrative. The people of Iran have the right to choose their own future freely and independently — without foreign powers dictating their options. Free Iran

I believe some Israeli scientists are beginning to react to what's happening in Gaza to avoid losing financial support from the European Commission.

What can we expect when the majority of Israelis still support Bibi and his criminal gang? Sadly, Israeli scientists are often not much different from the general population. It’s a harsh reality.
