- A Nature paper was shared: “Restoring metabolism of myeloid cells reverses cognitive decline in ageing” (https://www.nature.com/articles/s41586-020-03160-0), highlighting a potential intervention against age-related cognitive loss.

- Discussion of practical rapid-prototyping techniques for polycaprolactone (PCL): participants compared using an electric kettle or microwave to re-heat small water volumes for quick re-softening, versus a hair-dryer which risks overheating and sticking.

- A debate on the role of startups in biotech innovation was linked via Twitter: one thread argued that startups primarily commercialize existing academic inventions, citing BioNTech and Moderna’s mRNA platforms as examples built on prior academic work.

- Photogrammetry and 3-D printing were proposed as an alternative workflow to hand-molding PCL; one user reported that photogrammetry from SEM images proved harder than expected, prompting suggestions to try the open-source Meshroom pipeline and exploit SEM’s ultra-high resolution to overcome noise and feature-detection issues.

- General constraints on photogrammetry quality were summarized: insufficient image resolution, limited camera angles, and reflective or featureless surfaces—factors largely absent in SEM imaging, making it potentially well-suited for high-fidelity 3-D reconstruction.
