# Summary of IRC Log from #hplusroadmap (Feb 9, 2015)

• A research paper was shared about synergistic effects of sodium butyrate (a histone deacetylase inhibitor) on neurogenesis induced by pyridoxine, showing interest in compounds that may enhance neural proliferation in the mouse dentate gyrus.

• Discussion of historical medical imaging techniques included pneumoencephalography, a painful early brain imaging procedure where cerebrospinal fluid was replaced with air to make brain structures visible on X-rays, contrasting with modern CT technology.

• A user shared a 3D model of a Hilbert curve (a space-filling fractal curve) created using Python and BRL-CAD, demonstrating applications of computational geometry in 3D modeling.

• Participants discussed the concept of replicator technology (similar to Star Trek), debating whether established manufacturing interests would attempt to prevent such technology from being developed, with counterarguments comparing it to agricultural abundance.

• Several scientific papers were shared about emerging materials and technologies, including penta-graphene (a new carbon allotrope), DNA origami mechanisms for biomedical applications, and piezoelectric ZnO/AlN-stacked flexible nanogenerators for energy harvesting.

• A user inquired about the integration of Google Glass with EEG headsets, suggesting interest in brain-computer interface applications combined with augmented reality technology.
