In this episode, how polysaccharides keep cyanobacteria afloat in the oceans so that they can carry out photosynthesis, and a symbiotic bacterium that protects honey bees from fungal infections.
In this episode, hiring and training expectations for future biomedical life sciences faculty, and the roles of bacterial symbionts in deep-sea hydrothermal vent tubeworms.
The TWiM team reveals thousands of small novel genes in the human microbiome, and a mutualistic symbiosis between marine protists covered with magnetosome-containing bacteria.
The Microbials discuss how ambrosia beetles utilize ethanol to farm fungi, and how cleaved cochlin protein sequesters bacteria in the inner ear to preserve hearing function.
The TWiMpeeps discuss two symbioses: a parasitoid bacterium of a heterotrophic protist, and fungal parasites in cicadas.
The TWiM team explores a stingless bee that requires a fungal steroid to pupate, and colonic biofilms containing tumorigenic bacteria in patients with colorectal polyps.
The TWiMmers get cozy with symbionts: bacteria that allow a giant shipworm to oxidize sulfur, and algae that live within salamander cells.
Vincent, Elio, and Michael discuss a symbiosis between a nitrogen-fixing cyanobacterium and a single-celled eukaryotic alga.
Vincent, Elio, Michael, and Michelle discuss a symbiosis between a bacterium and fungus that increases the virulence of oral biofilms, and the assembly of amyloid fibers, which are needed for biofilm formation.
Vincent, Elio, and Michael discuss a huge 30,000 year old virus recovered from Siberia, and nested symbiosis facilitated by horizontal gene transfer from bacteria to insect.
