In this episode we review the literature from the past two weeks including a novel blood test for Alzheimer’s disease, an Anti-HIV gel, iPSCs and ring chromosomes and the generation of haploid stem cells. We then bring on an internationally recognized stem cell and cancer researcher Dr. Leonard Zon from Harvard Medical School and Boston Children’s Hosital. Dr. Zon talks to us about his work using zebrafish as a model to study cancer and melanoma and tells some really funny stories on his experiences with these fish. We close the show with a rant on laboratory sabotage. Enjoy!
