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.
 
Atheists Talk Radio Show is a weekly production of Minnesota Atheists. It airs in Twin Cities on AM 950 KTNF at 9:00 AM Sunday mornings or stream live at http://www.am950ktnf.com. Minnesota Atheists is Minnesota's oldest and largest atheist organization. We are a 501(c)(3) non-profit, educational organization that seeks to promote the positive contributions of atheism to society and to maintain separation of state and church. Our bylaws are available here. Each year we hold eight monthly mem ...

In COVID-19 clinical update #57, Daniel Griffin covers children and MIS-C, school opening plans, transmission event with masks, fomite transmission, diagnostic test performance, AZ vaccine and blood clots, and long COVID and the effect of vaccines. Hosts: Daniel Griffin and Vincent Racaniello Subscribe (free): iTunes, Google Podcasts, RSS, email Be…
 
The TWiM team reviews how variants of P. aeruginosa survive antimicrobial treatment, and a decrease in the antimicrobial resistance of the gut microbiome in the presence of the fungus C. albicans. Become a patron of TWiM. Links for this episode: Phoenix colony variants of P. aeruginosa (AAC) Candida and the gut microbiota (mSphere) Music used on TW…
 
The Guardians of the TWiV-o-verse discuss the process of codon deoptimization for the production of experimental infectious attenuated viral vaccines, and how a respiratory syncytial virus with 619 base changes was rescued by genomes with very large internal deletions. Hosts: Vincent Racaniello, Dickson Despommier, Rich Condit, Kathy Spindler, and …
 
Arturo Casadevall joins TWiV to discuss the use of convalescent plasma to treat COVID-19, including a history of the process, how plasma is prepared and tested, why it is difficult to conduct randomized clinical trials, how this treatment has fared and his hopes for the future.

In COVID-19 clinical update #56, Daniel Griffin note increasing hospitalization in children and young adults, Pfizer vaccine efficacy results in 12-15 year olds, rapid self administered nucleic acid and antigen tests, mRNA vaccine efficacy in real world conditions, and improvement of long COVID after vaccination. Hosts: Daniel Griffin and Vincent R…
 
John, Monica, and Davida join TWiV to discuss development of a method to detect SARS-CoV-2 in raw sewage from all 14 of New York City’s treatment plants, and its use to determine the presence of the genome throughout the pandemic and detection of genome mutations from variants of concern.

Alessandro Sette joins TWiV to discuss the role of T cells in COVID-19, the finding that amino acid changes in SARS-CoV-2 variants of concern have a negligible impact on T cell reactivity in convalescent patients and vaccinees, and whether a next generation vaccine should include more viral proteins than spike. Hosts: Vincent Racaniello, Alan Dove,…
 
In COVID-19 clinical update #55, Daniel Griffin reviews recommendations for keeping transmission low in school settings, optimal testing strategies for schools and businesses, impact of vaccines on asymptomatic infections, vaccine safety in PASC patients, and early use of aspirin associated with decreased mortality. Hosts: Daniel Griffin and Vincen…
 
Nels and Vincent review a preprint demonstrating that changes in the genomes of the SARS-CoV-2 variants B1.351 and P.1 allow the viruses to reproduce in mouse cells in culture and in laboratory mice.
