# Summary of IRC Log from July 10, 2012

• A paper on "Automated forward and reverse ratcheting of DNA in a nanopore at 5 angstrom precision" was shared, demonstrating the ability to ratchet DNA strands through nanopores at 2.5-40 nucleotides per second with one nucleotide spatial precision in real time, representing a significant advancement for DNA sequencing technology.

• Research on vertebrate magnetoreception was discussed, highlighting the discovery of magnetite-containing cells in rainbow trout that likely function as magnetic receptors by aligning to magnetic fields and exerting physical pressure on cell membranes to initiate nervous impulses.

• Significant wiki updates were made to the DIY H+ wiki, including content on germline genetic engineering, DNA synthesis techniques, transcranial ultrasound, protein engineering, myostatin manipulation, and various nootropics and cognitive enhancement approaches.

• The B9Creator high-resolution 3D printer was mentioned as having received $500,000 in Kickstarter funding, demonstrating growing interest in accessible advanced manufacturing technologies.

• A discussion about the BOOLE algorithm for CAD and surface intersection mathematics in BRL-CAD highlighted ongoing development in open-source 3D modeling software relevant to DIY manufacturing and design.
