The individuals who believe that certain types of gain-of-function experiments should not be done because they are too dangerous (including Lipsitch, Osterholm, Wain-Hobson,) cite the 1977 influenza virus H1N1 strain as an example of a laboratory accident that has led to a global epidemic. A new... Read More

A new drug acts as a roadblock for malaria, curing mice of established infection, according to a study in The Journal of Experimental Medicine. Treatment was not associated with obvious side effects, suggesting that the drug may also be safe and effective in humans. Read More
The microbiome of hibernating bears, and zebrafish as a model for bacterial sepsis feature in this animal-centric episode of TWiM hosted by Vincent, Michael, and Michele.

Back in 2013 I built a Wall of Polio in my laboratory – a large stack of six-well cell culture plates that have been used to measure the concentration of polioviruses in various samples by plaque assay. It became a focal point of the lab at which many guests came to have their photographs taken.... Read More
The Sabin infectious, attenuated poliovirus vaccines are known to cause vaccine-associated paralysis in a small number of recipients. In contrast, the Salk inactivated vaccine does not cause poliomyelitis. Why are the Sabin vaccines still used globally? The answer to this question requires a bri... Read More
Three reports have been published that together make a compelling case that Zika virus is causing microcephaly in Brazil. Read More
A permissive vaccine prevents disease in the immunized host, but does not block virus infection. Would a permissive vaccine lead to the emergence of more virulent viruses?
This hypothesis is based on the notion that viruses which kill their hosts too quickly are not efficiently transmitted, a... Read More
The TWiPanosomes solve the case of the Young Man from Anchorage, and discuss how cestode parasites increase the resistance of brine shrimp to arsenic toxicity.
Los virus son considerados por la mayoría como patógenos en todo tipo de entidades biológicas. Sin embargo la gran mayoría de los virus son inocuos a sus células hospedero. Nuestro invitado de hoy, el Dr. Paolo Zanotto es investigador y profesor en la Universidad de Sao Paolo, Bra... Read More
