- A PNAS paper titled “Prolonging healthy aging: Longevity vitamins and proteins” was circulated; it argues that adequate intake of certain “longevity vitamins” (e.g., ergothioneine, pyrroloquinoline quinone) and their associated proteins could extend healthy lifespan by slowing—not repairing—age-related damage.  
- Discussion framed the paper as offering modest value for life-extension strategies, noting its emphasis on slowing aging rather than reversing accumulated damage.  
- A related UCSF news release (https://www.ucsf.edu/news/2018/10/412016/perspective-adequate-consumption-longevity-vitamins-could-prolong-healthy-aging) and Hacker News thread (https://news.ycombinator.com/item?id=18252469) were provided for additional context.  
- Separately, a new privacy threat was highlighted: “Tracking users across the web with TLS session resumption” (arXiv:1810.07304, https://arxiv.org/abs/1810.07304), which details how TLS session tickets can be exploited for persistent user tracking even without cookies.
