# Key Points from IRC Log

• Microfluidics technology was discussed as a potential solution for mixing inks in printing applications, with debate about its practicality for consumer printers despite potential for high-quality photographic output.

• Users compared printing technologies, noting that LightJet photo printers achieve 300 dpi continuous tone images that provide visual resolution equivalent to 4,000 dpi on inkjet printers.

• DIY electroporator schematics were shared, including links to resources on pulse generators for electrofusion and electroporation, with discussion of devices operating in the 1.8-3.6 kilovolt range.

• The survival of biological cells in vacuum conditions was examined, with the consensus that most cells would rupture, though certain extremophiles like tardigrades and Bacillus subtilis spores can survive such conditions.

• Resources for microfluidic chip fabrication were shared, including "Order a Microfluidic Chip from the Foundry" on OpenWetWare, suggesting accessible manufacturing options for custom microfluidic devices.

• The DIYbio wiki (http://diybio.openwetware.org/) was referenced as a resource for DIY biology projects, though concerns were raised about OpenWetWare's user approval process and management.

• Quantified Mind (http://www.quantified-mind.com/) was shared as a platform for cognitive testing that uses videos rather than text descriptions while citing scientific sources.
