- A technical debate unfolded on the feasibility of electrostatic dipole sails in space, focusing on whether a static dipole can accelerate without an external electric-field gradient and how solar-wind Debye shielding (~10 m at 1 AU) and possible double-layer formation would affect thrust.  
- Participants requested and shared a review paper on solar-wind composition and interplanetary plasma: arxiv.org/abs/1301.2929.  
- Caltech’s “Scaling up molecular pattern recognition with DNA-based winner-take-all neural networks” (https://authors.library.caltech.edu/84840/) was highlighted as a new approach to large-scale DNA computing.  
- Elsevier’s press release about a “simple 3-D printer for metal” (https://www.elsevier.com/about/press-releases/research-and-journals/at-last-a-simple-3d-printer-for-metal) was discussed; users noted the material contains beryllium and may be hazardous, while the headline was deemed clickbait.  
- Gwern’s comprehensive essay on embryo selection for intelligence (https://www.gwern.net/Embryo-selection) was circulated as a key resource on polygenic screening and human enhancement.  
- A GitHub repository measuring memory bloat in popular web applications (https://github.com/dominictarr/your-web-app-is-bloated) was shared as a critique of modern software efficiency.  
- nmz787 reported successfully compiling and uploading the open-source FPGA code from a Hackaday tutorial on the MAX1000 board (https://hackaday.com/2018/08/31/max1000-tutorial-is-quite-persistent/) and is now reverse-engineering its 5×7 font ROM.
