- A new high-resolution 3-D reconstruction of the mouse brain was shared (MedicalXpress article), prompting discussion about the need for an open, interactive 3-D viewer that simply shows major brain regions and their interconnections rather than full electron-microscopy detail.

- Participants debated practical routes to such a viewer: one suggested building it in Panda3D once the connectivity data is available, while another proposed an automated pipeline that ingests serial electron-microscopy images and exports abstracted models for simulators.

- Antipragmatist2 reported completing the electronics for a home-built scanning-tunneling microscope (STM) and asked for alternatives to “diamonoid” as a construction material; silicon and piezoelectric (PZT) actuators were mentioned, along with the challenge of achieving fast 3-D nanopositioning for molecular assembly.

- A Warhammer tank CAD file on Thingiverse was taken down via DMCA, highlighting ongoing intellectual-property friction in the open-hardware community.

- A Flash zero-day exploit disclosed on the Dailydave mailing list was circulated as a security heads-up.

- Discussion of transhumanist outreach included the observation that the former WTA-talk mailing list is defunct due to poor technical maintenance and organizational neglect, and that Humanity+’s own links to its mailing lists were broken (404 errors).
