A pathogenic role for histone H3 copper reductase activity in a yeast model of Friedreich's Ataxia
Oscar A. Campos, Narsis Attar, Chen Cheng…·Siavash K. Kurdistani
The paper shows that reducing histone H3-mediated Cu1+ production restores Fe-S cluster deficiencies in yeast, linking chromatin and mitochondrial function to Fe-S cluster homeostasis.

TGFβ superfamily signaling regulates the state of human stem cell pluripotency and competency to create telencephalic organoids
Momoko Watanabe, Jillian R. Haney, Neda Vishlaghi…·Bennett G. Novitch
This study shows that maintaining human pluripotent stem cells with feeders improves cortical organoid formation by activating TGFβ signaling and naive pluripotency genes, which can be mimicked with TGFβ growth factors.
