015 Bacterial Magnificence with Jean-Marie Volland

Dr Jean-Marie Volland is a scientist at the Laboratory for Research in Complex Systems and an affiliate scientist at the Department of Energy Joint Genome Institute. He is also the lead author on a recent research paper that announced the discovery of something that most people, including biologists, had scarcely thought possible: a gigantic bacterium which is thousands of times larger than its fellow microbes – so large, in fact, that it can be seen with the naked eye. In this conversation, KMO and Jean-Marie discuss: 01:50 – Thiomargarita Magnifica and its discovery 05:05 – Geography refresher 06:25 – JM's stumbling into biology 10:20 – Etymological remarks 10:55 – Sulfur-eating lifeforms and KMO's mammalian privilege 13:15 – Bug size competition 13:55 – The three-domain classification (Eukarya, Archaea, Bacteria) 16:45 – Taxonomy of the living forms 18:38 – Reproduction and evolution 22:13 – T. magnifica's unusual structure (with a brief mention of Anton Petrov's YouTube videos) 26:20 – Evolutionary advantages of being large 30:00 – Cooperation and competition in the natural world and beyond (way beyond, including the economy); ramifications of this dichotomy; symbiosis, parasitism, and commensalism; why is symbiosis so abiding when its game-theoretical disadvantages are also evident? 44:40 – JM's two closing take-home messages Host and Guests: KMO: @Kayemmo | en.padverb.com/kmo Jean-Marie Volland (LRC Systems) Links and Resources: Thiomargarita magnifica (Wikipedia)
