This Week in Microbiology is a podcast about unseen life on Earth hosted by Vincent Racaniello and friends. Following in the path of his successful shows 'This Week in Virology' (TWiV) and 'This Week in Parasitism' (TWiP), Racaniello and guests produce an informal yet informative conversation about microbes which is accessible to everyone, no matter what their science background.

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. Hosts: Vincent Racaniello, Elio Schaechter, Michele Swanson and Michael Schmidt ### Links for this episode * Thousands of small novel genesin human microbiome (Cell) * A magnetotactic consortiumunder the sea (Nat Micro) * Image credit * Letters readon TWiM 203 Music used on TWiM is composed and performed by Ronald Jenkees and used with permission.
