- Discussion of why no vaccine exists for Toxoplasma gondii: intracellular parasites are hard targets, and toxoplasmosis has only “marginal negative effects” in humans, so commercial incentive is low compared with malaria.  
- Evidence was shared that humans naturally seroconvert and gain apparent immunity after infection, suggesting a conventional vaccine could in principle work.  
- Behavioral-study link: NIH paper (PMC2526142) reported toxoplasma–gender interactions on “Self-Control,” “Clothes Tidiness,” and “Relationships” factors, with infected men scoring lower on self-control and relationship warmth.  
- Hypothesis debated: toxoplasma infection may increase cat affinity, but participants noted the evidence is observational and inconsistent; a 2012 paper (PMC3497129) was cited as the first Google result on the topic.  
- Bacteriophage therapy was floated as an alternative intervention, but dismissed because phages cannot reach intracellular bacteria and the immune system rapidly clears them.  
- Brief mention of the UK ARCHER supercomputer cyber-attack (The Register article) as an example of critical research infrastructure vulnerabilities.
