A DNA test helps Fareed Zakaria find his roots far from India

His father was orphaned as a child, and Fareed does not know much about his background. Fareed and his mother took DNA tests that turned up some surprising results on their roots journey.

Hope riding on ZMapp

The Obama administration has asked three labs to scale up production of the experimental Ebola drug ZMapp. Dr. Kent Brantly and Nancy Writebol both received ZMapp before they were airlifted back to the U.S. Thomas Duncan and other patients were given other experimental drugs because there wasn't any more ZMapp. So far, it has not been studied in rigorous clinical trials and no one can say for sure that it actually helps patients.

Anderson discussed the hopes and risks of ZMapp with Chief Medical Correspondent Dr. Sanjay Gupta, former CDC disease detective Dr. Seema Yasmin and the University of North Carolina School of Medicine's Dr. William Fischer II.

Earlier this year, Dr. Fischer treated Ebola patients in Guinea where he was working with Doctors Without Borders. He wrote a series of moving e-mails that you can read here.
