- E-beam lithography tooling was discussed: participants noted that while the optics are complex to design and build, end-users don’t have to construct them from scratch, and the real breakthrough would be fabricating devices on plastic film so they could be mass-produced on a printing press.  
- GPT was cited as confirming that transmissive metalenses can function on plastic substrates, suggesting a path to roll-to-roll manufacturing of advanced optical components.  
- A link to a PYMNTS article was shared about a recent OCC hack that has prompted major banks to restrict information-sharing, highlighting emerging regulatory and cybersecurity concerns in financial infrastructure.  
- The open-source cheminformatics toolkit RDKit and its Python documentation on chemical reactions were posted, along with the SMILES-drawer web tool, underscoring ongoing interest in accessible molecular-design software.  
- A DIY game project called “Reactoids” was linked, illustrating grassroots experimentation with interactive simulations.  
- A Twitter video on sonochemistry was highlighted, describing how collapsing cavitation bubbles in liquids create plasma at sun-like temperatures, effectively turning each bubble into a self-contained microreactor—framed as “cavitation alchemy” for green chemistry.
