# Key Points from IRC Log

• BayesDB, a project from MIT's Probabilistic Computing Project, was shared as a tool for querying the probable implications of data, representing an early step toward more sophisticated probabilistic database systems.

• A discussion about mouse housing automation focused on using PVC pipes with air columns ("skydiving columns") for separating mice, using thermal imaging and air valves to route them, with debate about whether this approach was more scalable than traditional caging systems.

• A paper on the development of open heart surgery was shared (http://circres.ahajournals.org/content/35/5/661.full.pdf), providing historical context for surgical innovation.

• A tool called "getpapers" from the ContentMine project was highlighted as a useful academic paper scraper, along with news that Crossref API claims to have PDF links for 16 million DOIs.

• A discussion about selective breeding of mice for cryonics adaptation suggested focusing first on individual cell survival, then organ survival, before working up to whole-body resistance to cryopreservation.

• A news story about a cryotherapy business death prompted discussion about safety protocols, with suggestions that facilities should implement basic safety measures like pulse monitoring and proper emergency procedures.

• A user shared a pH equilibrium chart showing concentrations of carbon dioxide-based species in open-air solutions at various pH levels, relevant to environmental chemistry discussions.
