• Live-cell xenotransplant tourism: discussion of U.S. patients traveling to Germany to receive fetal-sheep-cell injections marketed as anti-aging therapy, framed as a form of inter-species chimerism and linked to the WHO “Second Global Consultation on Regulatory Requirements for Xenotransplantation Clinical Trials” report.  
• CRISPR-Cas9 patent landscape: shared Boston Review article “Who Owns Molecular Biology?” analyzing competing ownership claims and their impact on open biotechnology.  
• Practical CAD workflow advice: recommendation to run SolidWorks inside a virtual machine instead of relying on FreeCAD, whose frequent crashes are attributed to the underlying OpenCASCADE geometry kernel.  
• GDF11 self-experimentation follow-up: question about whether a previously discussed individual in his 50s has continued 1.5-year-long dosing with the putative rejuvenation factor.  
• Sci-Hub resilience: note that the paper-piracy platform is reachable at the new mirror http://www.sci-hub.io/.  
• Graph-isomorphism breakthrough: relayed news of László Babai’s quasi-polynomial-time algorithm and its potential implications for cheminformatics workflows.  
• Open-access precedent: citation of the 2001 mass resignation from Elsevier’s Machine Learning journal and the founding of the open Journal of Machine Learning Research (JMLR) as a model for resisting restrictive publishing.  
• DIY hardware prototyping tool: link to “Protopiper,” a hand-held adhesive-tape gun that extrudes hollow tubes for rapid, room-scale physical sketching of objects.  
• Stem-cell sourcing brainstorm: proposal to harvest stem cells from miscarried embryos and to maintain in-house blood/tissue banks at health-insurance companies to lower future treatment costs.  
• Hypothetical time-travel mechanics: outline of a scheme combining global cosmological reset with forward-only time machines to achieve effective backward travel, plus an alternative simulation-based method that halts computation to “rewind” subjective time.
