TWiV 1013: Bird flu around the world
TWiV reviews remarkable changes in the epidemiology of avian H5N1 influenza virus leading to previously uninfected areas, involvement of previously unaffected wild birds, and devastating outbreaks in farmed poultry, and isolation of a monoclonal antibody against the influenza virus neuraminidase that inhibits infection with a wide range of A and B isolates.

Why not vaccinate chickens against avian flu, and new form of reproduction found in yellow crazy ants
Why some countries, such as China, vaccinate flocks against bird flu but others don’t, and male ants that are always chimeras
First up this week, highly pathogenic avian influenza is spreading to domestic flocks around the globe from migrating birds. Why don’t many countries vaccinate their bird herds when finding one case can mean massive culls? Staff News Writer Jon Cohen joins host Sarah Crespi to discuss the push and pull of economics, politics, and science at play in vaccinating poultry against bird flu.
Next up, a crazy method of reproduction in the yellow crazy ants (Anoplolepis gracilipes). Hugo Darra...

How to make driverless cars safer — expose them to lots of dangerous drivers
00:46 A new test to get autonomous vehicles on the roadTruly autonomous vehicles, ones that don't require a driver to be present and are driven by AI, aren't yet safe for public use. Part of the reason for this is it has been difficult to train them to deal with rare dangerous situations. Now researchers are unveiling a new approach to present lots of these infrequent events to the AI very rapidly, speeding up the training and testing process.Research Article: Feng et al.News and Views: Hazards help autonomous cars to drive safelyVideo: The driving test for driverless cars08:23 Research HighlightsHow bird-flu is adapting t...

TWiV 777: SARS-CoV-2 fitness with Ron Fouchier
Ron Fouchier explains why increased transmission of SARS-CoV-2-variants has not been demonstrated, and their ability to displace ancestral variants is due to greater fitness, much like influenza virus antigenic variation leads to better fitness and replacement of previously circulating variants.

The 2019 Novel Coronavirus Outbreak – Update From NIAID’s Anthony Fauci, MD
In February 2020 the nature of the 2019-nCoV outbreak is still slowly coming into focus but it appears to be acting more like bad pandemic influenza (efficient spread, overall lower mortality) than like SARS (less efficient spread, overall higher mortality). Anthony Fauci, MD, of the US National Institute of Allergy and Infectious Diseases (NIAID) discusses the latest developments with JAMA Editor in Chief Howard Bauchner.
