Neanderthal DNA Persists in Humans
When modern humans migrated out of Africa between 100,000 and 60,000 years ago, they encountered and bred with Neanderthals, our close relatives living in Europe and Asia. For people of non-African descent, approximately 2 percent of their genome has some Neanderthal DNA. New research is investigating which components of the Neanderthal genome survive today—and what traits they influence.
Could Cat Color Help Us Solve Obesity Problems?
Calico cats might be the key to figuring out why certain diseases like cancer, hemophilia, and obesity are passed down and others are not.
Can We Genetically Improve Intelligence?
Are we able to create genius babies? The answer might surprise you! Find out what science has to say in our latest video.
Are We Finally Ready To Clone A Mammoth?
Everyone keeps asking scientists when they’re going to clone a woolly mammoth. It’s not the easiest thing to do, but they are working on it! Trace is here to discuss with you how we’re planning on bringing back extinct animals, and how recent discoveries are helping this process.

Use of Human Induced Pluripotent Stem Cells for Predicting Diverse Cardiotoxicities
The development of human induced pluripotent stem cell (iPSC)-derived cell lines as models for drug-toxicity testing offers a promising alternative that is more physiologically relevant, more predictive, and more time and cost efficient. Although iPSC-derived cardiomyocytes have not yet replaced well-established FDA-approved toxicological methods, the FDA has fast-tracked efforts to standardize the use of stem cell-derived cardiomyocytes in the next two years. The Scientist brings together a panel of experts to discuss the successes and caveats of using iPSC-derived cells in toxicological assays.

Can Gene Therapy Cure Blindness?
Over the past decade, researches have been testing gene therapy on blind dogs in attempt to restore vision. Earlier this week, six patients in Oxford had this same treatment done, and they’re reportedly cured! Join Trace as he shines some light on the steps scientists have taken to get to this point, and questions if gene therapy can ultimately be the cure for blindness!

Why RNA is Just as Cool as DNA
DNA is always hogging the limelight. We’re here to tell you why RNA is just as important (and as cool) as DNA! We’ll compare and contrast RNA with DNA and also talk about the three types of RNA. This video sets the stage for protein synthesis.

Where Did We All Come From? Tracing Human Migration Using Genetic Markers
Presented by Professor Moses Schanfield.
Of all species on the face of the earth, humans are the most disperse, in that they occupy the most diverse eco-systems present on all large land masses and most large islands.
In recent time, much work has been done using maternally inherited mitochondrial DNA, and non-recombinant Y (NRY) chromosome markers to map human migration and ancestry. In addition, large numbers of other DNA based markers have been used for similar purposes. However, anthropological geneticists have been looking at human migration and ancestry for as long as there have been genetic markers, starting with the ABO blood groups.
This talk reviews some of the realities and unrealities of ancestry testing, as done by commercial laboratories such as Ancestry.com, as well as the overall patterns of human migration and conclusions that can be made about modern humans in the last 100,000 years.
Professor Schanfield is a world authority on the genetic markers on antibodies, and has applied genetic marker testing, both protein- and DNA-based, to the study of anthropologic and forensic genetics. He was involved in some of the earliest forensic DNA cases, and has been involved in some famous forensic cases including the OJ Simpson case and the JonBenét Ramsey case. Professor Schanfield is a co-editor of the book Forensic DNA Applications: An Interdisciplinary Perspective with Professor Dragan Primorac which will be released in February 2014 by Taylor and Francis. He is currently Professor of Forensic Science and Anthropology at George Washington University.
Professor Schanfield has undergraduate and Masters Degrees in Anthropology from the University of Minnesota and Harvard University, respectively and a Ph.D in Human Genetics from the University of Michigan.

Are Men Going Extinct?
For 3 years now, it has been widely debated whether or not the Y chromosome will disappear. Will men cease to exist on Earth without the gene that created them? Anthony takes a look at recent findings in regards to genetics and the slow demise of the Y chromosome.
