- A Science Translational Medicine paper on restoring cognitive function in aging mice via systemic factors was shared (DOI: 10.1126/scitranslmed.3006373).  
- A Science paper showing that poverty measurably reduces cognitive capacity was discussed; participants noted the lab findings may not translate to real-world settings (DOI: 10.1126/science.1238041).  
- A Frontiers in Pharmacology study on flavonol-rich dark cocoa improving cognition in urban children was circulated (full PDF retrieved).  
- nmz787 reported initial success using a 405 nm laser and a DLP projector to expose photoresist, a step toward low-cost micro-lithography for DNA-synthesis hardware.  
- Genentech’s K-12 science-education grant program was investigated; it requires 501(c)(3) status or tribal affiliation even for non-philanthropic science projects.  
- An extended technical debate explored why ROVs remain tethered: seawater strongly attenuates RF, VLF penetrates only ~20 m, ELF reaches hundreds of meters but only one-way, and submersible relay “cucumber Wi-Fi” concepts were floated.  
- chris_99 asked about fabricating microfluidic logic gates; kanzure clarified that microfluidic “transistors” are actually configurations of micro-valves, and the group referenced electrowetting-based digital microfluidic arrays demonstrated in a linked YouTube video.
