- A new 3-D nanofabrication technique called “implosion fabrication” was highlighted: patterned polymer scaffolds are volumetrically infused with metals, semiconductors or biomolecules and then isotropically shrunk to nanoscale dimensions, effectively reversing the principle of expansion microscopy (Science 362:1281, MIT news summary).  
- The method enables rapid, low-cost production of complex 3-D nanostructures—including conductive wires and optical metamaterials—without conventional lithography, suggesting open-source routes for advanced transhumanist hardware such as neural interfaces or nanoscale sensors.  
- Discussion linked the technique to broader DIY nanotech possibilities, noting that the required materials (acrylate scaffolds, metal salts, acid diffusants) are bench-top accessible and that shrinkage can exceed 10× in each dimension.  
- A cryptography paper on “Batching techniques for accumulators with applications to IOPs and stateless blockchains” was shared (eprint 2018/1188), proposing efficient zero-knowledge set-membership proofs that could underpin privacy-preserving decentralized identity or reputation systems for biohacker communities.  
- A critical SQLite remote-code-execution vulnerability (Magellan, CVE-2018-20346) was circulated together with the upstream patch commit, underscoring the need for hardened local databases in personal health-tracking and lab-automation stacks.
