• A 2002 PRL paper on “Confinement-Induced Entropic Recoil of Single DNA Molecules” was discussed: 35-nm-pillar nanofluidic chips fabricated by e-beam lithography and sacrificial-layer etching can sort DNA by length because short strands fully enter the “pillar forest” and are kicked across by voltage pulses, while long strands bounce back, offering a possible music-driven interactive art installation using human saliva samples.

• The fusor.net amateur-fusion forum has gone offline with its entire post database lost; participants hope backups exist and speculate whether recent cultural conflicts contributed to the outage.

• A Hacker News thread about extreme lifelogging-induced psychological breakdown was shared, prompting commentary on the need for privacy and ergonomic work environments—one participant advocated VR-equipped isolation tanks over open-plan offices.

• A Bitcoin “burn instead of steal” attack vector was proposed: an adversary could provably destroy victims’ coins (via CoinJoin burns) to increase scarcity and profit from price appreciation while gaining a large anonymity set; debate followed on whether market impact would offset confidence loss.
