- A new preprint titled “From Space to Sequence and Back Again” (biorxiv.org/470211v1) describes an iterative DNA proximity-ligation method that encodes physical location into DNA, enabling molecular-level imaging and spatial pattern recovery via sequencing.  
- Discussion of Landauer’s principle and its practical relevance: participants noted that current Bitcoin-mining ASICs perform only irreversible computation and are still many orders of magnitude away from the theoretical energy limit.  
- A Nature Electronics paper (s41928-018-0161-6) on “electronic-skin compasses” was shared, outlining wearable devices that provide geomagnetic-field-driven artificial magnetoreception for interactive electronics.  
- A Next Big Future article was linked claiming that mass genetic modification of most adult cells could soon become as simple as a vaccination-style injection, sparking interest in scalable in-vivo gene-editing delivery.  
- A brief aside highlighted striking rectangular icebergs (sci-news.com/featurednews/rectangular-icebergs-06534.html) as an example of naturally occurring geometric phenomena.
