- A Python script for generating arc-length-parameterized spirals was shared (http://fennetic.net/pub/irc/lengthspiral.py and http://fennetic.net/pub/irc/spiral3.png) to help correct the non-uniform spacing seen in an early membrane-less filtration spiral design (http://heybryan.org/bioreactor/membraneless_filtration/2008-12-16_spiral_generator_2_other_issue.png).  
- Discussion of BRL-CAD workflow: rotating cross-sections with the orot command before converting them to regions/combs, and the observation that orot only affects primitives, not regions.  
- A standalone, Cairo-based version of the spiral generator was committed to a new git repository (http://fennetic.net/git/cxf2cnc.git/) to make the tool easier to test and iterate on.  
- Links to several research items: a Japanese fMRI paper on image reconstruction from brain activity (stored in http://heybryan.org/~bbishop/docs/), a DNA-nanomachine paper from Turberfield’s group (http://ftp.aip.org/epaps/phys_rev_lett/E-PRLTAO-101-091848/Coordinated_chemomechanical_cycles_EPAPS.pdf), and the OpenBUGS Bayesian/MCMC software suite (http://mathstat.helsinki.fi/openbugs/).  
- A brief debate on whether DNA can behave as a superconductor, sparked by claims that rhenium electrodes induce apparent superconductivity in DNA and speculation about magnetic-field effects on DNA repair mechanisms.  
- A critique of Eliezer Yudkowsky’s communication style on Overcoming Bias, with kanzure_ compiling a set of counter-arguments and references at http://heybryan.org/eli.html.
