- The channel debated the ethics and etiquette of open-source attribution after a member published a new GitHub repository (delinquentme/OpSci) without referencing earlier collaborative work done in the channel; the maintainer later added a README shout-out to acknowledge the broader community.

- A Broad Institute blog post on microfluidics for biology (http://www.broadinstitute.org/blog/sneak-preview-miniature-science-how-microfluidics-powering-biology) was shared as an example of miniaturized lab technology.

- Discussion of an ultra-miniaturized insect nervous system: the parasitoid wasp M.mymaripenne operates with only 7,400 neurons—100× fewer than a housefly—by shedding most neuronal nuclei during metamorphosis, yet still performs flight, foraging, and egg-laying (Polilov 2011, Arthropod Structure and Development).

- A new RepRap blog post on 3-D printing sugar scaffolds for tissue engineering was highlighted (http://blog.reprap.org/2012/07/on-challenge-of-3d-printing-sugar-for.html), with one participant noting their acceptance as a core RepRap developer.

- Members asked for and discussed online communities focused on “brain modification” techniques such as tDCS, TMS, nootropics, and cognitive training; no single high-quality subreddit or forum was identified.

- The group compared two browser-based circuit-design start-ups—CircuitLab and Upverter—and noted prior contact with the Upverter team.

- A call from Australia about Reese Jones’s new venture “Cambrian Genomics” was reported, indicating growing external interest in the channel’s network.

- Participants sought progressively more complex CAD benchmark objects (e.g., ISO-standard plates with holes, screws) to test a new open-source CAD library.
