"A Russian missile wiped out an entire family. Will this photograph stop the war? Most likely not. But I believe the world needs to see the truth," said photographer Yefrem Lukatsky. "I hope those whom this photograph will hurt can forgive me. Kyiv, July 6, 2026," he added.

Astrocytes do so much more than any of us thought - they even communicate among specific brain regions across hemispheres! The journey to this paper spanned nearly a decade, but I'm most excited to see what everyone else does with the tools we've built. There's so much for all of us to explore!

Astrocytes connect specific brain regions through plastic networks - Nature

Communication between distant brain regions is mediated by plastic networks of gap junction-coupled astrocytes.
