- A new paper (Wiley, Aging Cell) suggests vitamin D supplementation may worsen Alzheimer’s disease risk or mortality via a VDR-p53 mechanism, prompting debate over nutrient balance and cofactor interactions.  
- Karl Pfleger’s Twitter thread summarized the paper and flagged the need for further mechanistic study while listing methodological caveats.  
- Discussion pivoted to the general principle that any essential nutrient can appear harmful when other nutrients are deficient, referencing Weston A. Price Foundation writings on nutrient synergy.  
- A TU Delft press release was shared about the “smallest hard disk,” demonstrating atom-by-atom data storage using chlorine vacancies on copper, highlighting ultra-dense memory research.  
- The SC4.us HSM (Hardware Security Module) link was examined; participants noted that its keys reside in ordinary on-die flash memory and are therefore vulnerable to known physical extraction techniques.  
- Participants debated the feasibility of truly secure key storage, concluding that even Intel’s secure enclaves and on-die flash can be read by sufficiently motivated attackers.  
- An Hacker News thread on “Intel Microcode Decryptor” was circulated, underscoring ongoing advances in microcode reverse-engineering and hardware-level security exploits.
