# Summary of IRC Log from April 20, 2016

* A link to a new Bitcoin Improvement Proposal (BIP 374) was shared, which appears to be related to Bitcoin development discussions that had previously caused disagreements about censorship accusations.

* Heath shared information about "Pathogen-Extracting Sepsis Therapy," a medical technology likely related to treating blood infections by removing pathogens directly from the bloodstream.

* A discussion about browser tab management revealed different approaches to information management, with some users preferring to keep dozens of tabs open instead of using bookmarks, and others suggesting tag-based bookmark management systems like "jotmuch."

* Kanzure shared a link to "symbiolab/bio-labware," an open-source collection of DIY laboratory equipment designs and documentation for biological research.

* A user shared information about electroplating copper at 50 nanometers per second, suggesting this could be a practical approach for nanoscale 3D printing in metal, referencing the ASM Specialty Handbook on "Copper and Copper Alloys."

* A research paper was shared about corvid cognition showing that crows have "abstract rule neurons" in their endbrain that support intelligent behavior, suggesting that intelligence in vertebrates doesn't necessarily require a neocortex but can evolve through convergent evolution.

* FreeCAD 0.16 release notes were shared, indicating ongoing development in open-source CAD software relevant to DIY fabrication communities.
