Episode Info: Genetic Origins of the Americans, Diabetes and News Roundup A Weekly Conversation About Science, Health And The Power Of Knowledge To Transform Our Lives. - The Obesity Weight Loss Study: Reversal of obesity-associated inflammation and crown-like structures with acute weight loss Dr. Jose Aleman has a long standing interest in technology development to study common metabolic diseases as Type 2 Diabetes, cardiovascular disease and obesity. Born and raised in Puerto Rico, Dr. Aleman migrated to the US mainland to complete a bachelor’s degree in Chemical Engineering from Cornell University in 2001. Following a Fulbright Grant to Spain, Dr Aleman completed his MD-PhD studies at Harvard Medical School and MIT in 2009. For his PhD in Medical Engineering, Dr. Aleman developed flux analysis techniques for the study of transgenic mouse models of Type 2 Diabetes in collaboration with the Joslin Diabetes Center. He is pursuing a Medical Research Residency and Endocrinology Fellowship at Cornell Medical Center, while joining the Breslow lab as part of the Clinical Scholars Program.     - Unravelling the hidden ancestry of American admixed populations Francesco Montinaro,George B.J. Busby,Vincenzo L. Pascali,Simon Myers,Garrett Hellenthal & Cristian Capelli The movement of people into the Americas has brought different populations into contact, and contemporary American genomes are the product of a range of complex admixture events. Here we apply a haplotype-based ancestry identification approach to a large set of genome-wide SNP data from a variety of American, European and African populations to determine the contributions of different ancestral populations to the Americas. Our results provide a fine-scale characterization of the source populations, identify a series of novel, previously unreported contributions from Africa and Europe and highlight geohistorical structure in the ancestry of American admixed populations.   ABOUT: At, we believe in the transformative power of science, information, and knowledge.
