• A Substack post titled “How my large intestine was stolen” recounts an alleged unauthorized emergency surgery performed in Florida for elective reasons, raising questions about medical consent and ethics.  
• Molecular-dynamics simulations of nanoscale gears were shared: Al Globus’ work at NASA Ames shows 200–300 K thermostated runs in which gears jam in an inert atmosphere; raw video and additional files are available at http://alglobus.net/NASAwork/ and https://fennetic.net/irc/nanogears_by_alglobus.mpg.  
• New open-source voice-cloning tools were highlighted: VoiceCraft (GitHub: jasonppy/VoiceCraft), OpenVoice from MyShell.ai, and related Hacker News discussion (item 39861578).  
• A 3-D-printing breakthrough for mass-producing microscale particles was posted: researchers developed a technique enabling high-throughput fabrication of micron-sized objects (3DPrintingIndustry.com article).  
• The Debian xz-utils backdoor (CVE-2024-3094) was discussed; participants noted the awkward dependency chain where dpkg itself relies on xz, illustrating the “dependency vulnerability” xkcd #2347 scenario.
