Today I learned that a number of investigators refuse to share their samples of Zika virus with other laboratories. There are countless stories about scientists not sharing reagents because they want to be the first to make a discovery.

The study's reported findings--that cognitive behavior therapy and graded exercise therapy are effective treatments for chronic fatigue syndrome--have had enormous influence on clinical guidelines for ...

On episode #375 of the science show This Week in Virology, the TWiVziks present everything you want to know about Zika virus, including association of infection with microcephaly and Guillain-Barré syndrome, transmission, epidemiology, and much more. You can find TWiV #375 at microbe.tv/twiv.
