Beautiful pictures—thanks for sharing, @kasiagrochowska.bsky.social

Congratulations again on the new system. It's great to see that it's being put into action so quickly and successfully.

We look forward to more great pictures in the future ;)

The beauty of these images will never stop amazimg me. Hippocampal (CA1) neurons expressing an artificial cytoplasmic protein partially targeted to lysosomes (black dots).

Grateful to have had the chance to connect to many old friends and to make new ones at the incredible "Bee and Fly Neuroethology Meeting" at the Harnack house of the @maxplanck.de in Berlin.
The energy around new discoveries and brilliant scientists was infectious, and inspiring.
