#552 The First Cell
This week we take a closer look at what cancer is, how it works, and what makes it so hard to treat without shying away or ignoring the human experience of cancer for patients and their families. We talk with Dr Azra Raza, oncologist, Professor of Medicine, Director of the MDS Center at Columbia University, and author of the new book "The First Cell and the Human Costs of Pursuing Cancer to the Last".

The Other Latif: Episode 3
The Other Latif Radiolab's Latif Nasser always believed his name was unique, singular, completely his own. Until one day when he makes a bizarre and shocking discovery. He shares his name with another man: Abdul Latif Nasser, detainee 244 at Guantanamo Bay. The U.S. government paints a terrifying picture of The Other Latif as Al-Qaeda's top explosives expert, and one of the most important advisors to Osama bin Laden. Nasser's lawyer claims that he was at the wrong place at the wrong time, and that he was never even in Al-Qaeda. This clash leads Radiolab's Latif into a years-long investigation, picking apart evidence, attempting to separate fact from fiction, and trying to uncover what this man actually did or didn't do. Along the way, Radiolab's Latif reflects on American values and his own religious past, and wonders how his namesake, a fellow nerdy, suburban Muslim kid, may have gone down such a strikingly different path.   Episode 3: Sudan Latif turns his focus to Sudan, where his namesake spent time working on a sunflower farm. A sunflower farm owned... by Osama bin Laden. Latif scrutinizes the evidence to try to discover whether - as Abdul Latif's lawyer insists - it was just an innocent clerical job, or whether - as the government alleges - it was what turned him into an extremist fighter.  This episode was produced by Suzie Lechtenberg, Sarah Qari, and Latif Nasser.  With help from Niza Nondo and Maaki Monem. Fact checking by Diane Kelly and Margot Williams. Editing by Jad Abumrad and Soren Wheeler. Original music by Jad Abumrad, Alex Overington, Jeremy Bloom, and Amino Belyamani.  Support Radiolab today at Radiolab.org/donate.
