• A public aptamer database (http://aptamer.icmb.utexas.edu/) was surfaced, leading to speculation about engineering aptamers that selectively bind heavy metals such as iron or plutonium for sensing or remediation applications.

• Experiments showing that Drosophila larvae reared in 40 % oxygen atmospheres develop enlarged tracheae (http://jeb.biologists.org/cgi/content/abstract/207/20/3559) were highlighted as a concrete route to engineering “giant insects” by manipulating environmental oxygen levels.

• genehacker proposed an open-source hardware project to build an inexpensive, widely reproducible DNA synthesizer, but noted that sourcing or synthesizing the required phosphoramidite and other reagents remains the primary bottleneck; kanzure suggested documenting all known synthesis pathways in SKDB to accelerate replication.

• A transparent, dye-sensitized photovoltaic eye-tracking system (paper link shared) that measures pupil position without cameras was discussed, along with ideas for closed-loop feedback between visual-cortex activity and the display to create adaptive augmented-reality overlays.

• Scanpath theory (Noton & Stark, 1971) was revisited: eye-movement sequences form reusable spatial models for object recognition, and recent work shows that subliminal red-dot cues can externally guide or disrupt these scanpaths, raising the possibility of deliberately “de-training” expert cognition (e.g., making Sudoku harder for seasoned players).

• Multispectral data-overlay concepts were brainstormed, including flickering colors to induce non-spectral “octarine” perception and LCD sun-blocking pixels on windshields that can selectively occlude or transmit wavelengths to embed extra information without hindering normal vision.

• A 40 MB/s mirror of bioinformatics papers was shared at http://bio.cc/Bioinformics/papers/, and a UT-hosted glovebox status page (http://146.6.83.129/GloveboxStatus.html) plus acquisition of a YAG laser were noted, with discussion of CO₂ lasers capable of fabricating their own mirrors.

• India’s initiative to issue biometric ID cards to 1.2 billion citizens—many lacking any documented identity—was framed as the largest civil-registry project in history, with implications for identity, privacy, and state capacity.
