- A participant reported observing “random tiny particles” (≈1/100 the diameter of the pellets) floating in the water used to melt plastic pellets, speculating they might be micro-plastic flakes, mineral precipitates from hard water, or electrostatically attracted dust.  
- The same user noted that the plastic pellets exhibit slight adhesion to ceramic surfaces, unlike the non-stick behavior observed with polyethylene containers, suggesting material-dependent surface interactions.  
- Discussion centered on possible contamination sources: mechanical abrasion during shipping, residual dust from bag handling, or thermal flaking of molten plastic adhering to container walls.  
- Another member requested a link to a purported scanning-electron-microscope (SEM) image of semen taken by Ben Krasnow, but no such content was found in public records or prior posts.  
- The biopunk.org domain (linked from the DIYbio FAQ at diyhpl.us/wiki/diybio/faq) was reported to return HTTP 500 errors, raising questions about the site’s current status or migration.
