# Key Points from #hplusroadmap IRC Discussion

• A participant described their work on a laser CNC lithography system targeting 100 micron resolution initially, with plans to use a Bluray writer laser head to achieve sub-micron resolution for microreactor fabrication.

• The open hardware ultrasound project Murgen (http://murgen.echopen.org/) was discussed, including a related paper on super-resolution ultrasound that uses microbubbles to image at resolutions higher than the ultrasound wavelength itself.

• Several research papers were shared on diverse topics including "starivore extraterrestrials" (binary stars as metabolic systems), optical manipulation of aerosols for space construction, and neuroscience research on DNA methylation in memory formation.

• Advanced microscopy techniques were discussed, including environmental SEM (eSEM) for low-vacuum imaging of chemical reactions and Focused Ion Beam (FIB) technology for site-specific analysis and material manipulation.

• A participant shared plans to start a business manufacturing micro pumps, water blocks, engines, and custom scientific equipment at lower costs to make these technologies more accessible to hobbyists and researchers.

• The existence of underground biohacking communities was noted, particularly private steroid forums where users engage in citizen science and self-experimentation with hormones, highlighting informal experimentation happening outside traditional research settings.
