# Summary of #hplusroadmap IRC Log (January 15, 2017)

* A significant paper on "Imaging proteins at the single-molecule level" was shared, highlighting a breakthrough technique using low-energy electron holography to image individual proteins on graphene without needing to average over many molecules, representing a potential advance for structural biology.

* A video on "Proposal for Atomically Precise Manufacturing by the US Department of Energy" was discussed, indicating ongoing governmental interest in molecular manufacturing technologies.

* Several neuroscience research resources were shared, including papers on advanced fluorescence protein-based synapse-detectors, CLARITY-compatible lipophilic dyes for electrode marking, and a comprehensive summary of viruses used in neuroanatomical tracing.

* Participants discussed the technical aspects of phased array optics, including potential applications for VR displays and remote manufacturing, with references to a website dedicated to phased array optics for VR created by Brian Wowk, who is active in cryonics research.

* A discussion about laser technology covered the costs of high-powered lasers (noting that solid-state kW lasers cost approximately $100k per kW), with participants comparing CO2 lasers to semiconductor-based alternatives and examining their applications in manufacturing and potential megastructure applications.

* A novel metal 3D printing technology using molten aluminum droplets controlled by oscillating magnetic fields was shared, with claims that it could eventually print steel at 1,400°C and potentially offer advantages over laser sintering methods.
