# Summary of IRC Log from June 4, 2009

- A significant research paper archive was shared, with kanzure announcing a 3.4GB backup of scientific papers available at specified URLs, including a specialized collection on microfluidics.

- Discussion of alternative nucleic acids occurred, with genehacker noting that GNA (glycerol nucleic acid) might be simpler to synthesize than DNA, sharing a paper by Szostak demonstrating that polymerase can read GNA templates: "Enzymatic synthesis of DNA on glycerol nucleic acid templates."

- Concerns about DIYbio community interactions with policymakers and press were raised, with genehacker suggesting a "rule" to avoid talking to the press as it "won't turn out well," indicating tensions around regulation and public perception.

- Technical discussion about Bst polymerase was initiated, with kanzure noting it looks "neat" and sharing a paper link about DNA synthesis on glycerol nucleic acid templates.

- Mathematical concepts were briefly explored, including matrix concatenation properties and the concept of "virtual work" in physics, where "the total virtual work of the impressed forces plus the inertial forces vanishes for reversible displacements."
