- A new semantic-search tool for arXiv abstracts (papermatch.mitanshu.tech) was shared; it uses MixedBread embeddings + Milvus vector search, updates weekly from Kaggle metadata, and trades exact keyword matching for broader conceptual similarity—illustrated when a “Longevity HIIT” query returned papers lacking the literal acronym.  
- Discussion framed this as an expected limitation of semantic vs. ranked keyword search and noted that hybrid approaches could be complementary.  
- Eon Systems (eon.systems) surfaced as a new venture apparently combining Nectome’s high-resolution brain-preservation tech with “millions of electron microscopes on a chip,” though the exact relationship between the two organizations remains unclear.  
- Participants explored “knowledge distillation” as a brain-upload alternative: instead of atom-level scanning and emulation, one could train a compact neural network to predict the activations of a living brain recorded via a sparse array of transceivers, bypassing structural reconstruction and hardware-specific emulation challenges.  
- Practical hurdles noted: the need for long-term, high-coverage functional recordings, ethical/experiential issues of state-space stimulation, and the risk that the “student” architecture learns differently from the biological original.  
- Greg Egan’s short story “Learning to Be Me” (a jewel-shaped neural prosthesis that gradually replaces the wearer’s identity) was cited as prior art on gradual mind uploading and transition dreams.  
- An ant-colony problem-solving video was linked on Neuromatch Social as an example of emergent collective intelligence.  
- The open-source VR chemistry builder msep.one (GitHub: MSEP-one/msep.one) was announced for community testing.
