# Summary of ##hplusroadmap IRC Log (May 28, 2011)

* Cadmium, a lightweight 3D modeling tool using Python scripts with CGAL integration, was announced on the OpenSCAD list, featuring no GUI and minimal dependencies.

* A discussion about CGAL (Computational Geometry Algorithms Library) questioned its capabilities beyond polyhedral boolean operations, specifically whether it supports manifold surface boolean operations.

* A Nature paper titled "Induction of human neuronal cells by defined transcription factors" was shared, indicating interest in cellular reprogramming techniques.

* A technical discussion about genome sequencing coverage explained that higher coverage (35x mentioned) helps overcome errors in base calling and assembly, with coverage defined as the average number of times a nucleotide is represented in reconstructed sequences.

* A blog post about "the longest cell in the history of life" prompted questioning whether anatomists truly agree that nerves are single cells.

* The Human Brain Project was mentioned with a German article discussing pharmaceutical companies' challenges in medication development.

* Community members discussed resources for RepRap 3D printer parts, with recommendations to check eBay and #reprap IRC channel for sourcing components.
