Very sad news. Our group had the great fortune to collaborate with him and his group and to be inspired by his passion for science and patience for those of us not in the field. We are forever grateful to have had that opportunity.
With deep sadness, we share that Prof. Jochen Guck, Director at the Max Planck Institute for the Science of Light passed away on October 3. His visionary work bridged physics and medicine. We have lost a brilliant scientist and dear friend.

How important is #epigenetics for human brain?
Researchers led by @mareikealbert.bsky.social used brain organoids 🧠 🧫 and Epi-CyTOF to show that histone methylation controls how brain cells multiply and how big the organoid grows.
