- A Nature paper on “Integer factorization using stochastic magnetic tunnel junctions” was circulated; the PDF was obtained via an alternative mirror after Sci-Hub links were briefly inaccessible.  
- A short video of uranium in a cloud chamber (showing continuous radiation emission and decay tracks) was shared from Twitter, followed by links to longer YouTube demonstrations of thermoelectric cloud chambers for educational use.  
- Participants discussed a zero-equipment method to test whether a car key-fob is transmitting RF: coil a wire around the fob, plug the wire into a computer’s microphone jack, and listen for clicks at maximum volume.  
- A brief survey on five classical human genetic traits (ear-lobe attachment, mid-digit hair, widow’s peak, hair curliness, cleft chin) was conducted in-channel to help a student collect data for a biology assignment.  
- An SEM image of frost crystals was linked from Wikipedia as an example of high-resolution low-temperature microscopy.
