Four years after filming ‘Threading the NEIDL’, Vincent and Alan return to the National Emerging Infectious Diseases Laboratory BSL4 facility at Boston University where they speak with science writer David Quammen.

Vincent travels to Albert Einstein College of Medicine where he speaks with Kartik, Ganjam, and Margaret about their work on Ebolavirus entry, a tumor suppressor that binds the HIV-1 integrase, and the entry of togaviruses and flaviviruses into cells.

Vincent, Alan, and Kathy continue their coverage of the Ebola virus outbreak in West Africa, with a discussion of case fatality ratio, reproductive index, a conspiracy theory, and spread of the virus to the United States.

Recording together for the first time, the TWiV team celebrates their 300th podcast at the American Society for Microbiology headquarters in Washington, DC, where Vincent speaks with Dickson, Alan, Rich, and Kathy about their careers in science.
