# Summary of IRC Log from December 2, 2016

• JayDugger shared a paper from arXiv (1611.08368) proposing that stellar engineering could account for the unusual light patterns observed at Tabby's Star (KIC8462852), representing an interesting intersection of astronomy and potential advanced civilization hypotheses.

• A discussion about Reaction Engines' advanced heat exchanger technology occurred, with questions about why the company doesn't commercialize this technology more broadly beyond aviation applications.

• Several scientific papers on bioluminescence were shared, including research on the evolution of bioluminescence in marine fishes and applications for in vivo monitoring of fungal infections, highlighting potential biotechnology applications.

• A paper titled "Gut microbiota regulate motor deficits and neuroinflammation in a model of Parkinson's disease" was shared, pointing to the growing understanding of gut-brain connections in neurodegenerative disorders.

• The Integrated Space Plan was discussed (https://integratedspaceanalytics.com/cms/plan), which maps out potential future space development including human interstellar expansion, providing a roadmap similar to the hplusroadmap but focused on space exploration.

• A link was shared about research suggesting that old blood may have more pronounced negative effects than young blood has positive effects, contradicting some popular press narratives about parabiosis experiments.

• An article about "excitable mitochondria" was shared (http://inference-review.com/article/the-excitable-mitochondria), exploring advanced concepts in cellular biology.
