Ep. 41: “Chromosomal Disorders” Featuring Dr. Eirini Papapetrou

Guest: Dr. Eirini Papapetrou, an associate professor at the Icahn School of Medicine at Mt. Sinai where she discusses her work and latest paper on using stem cells to model blood diseases containing a chromosomal deletion. Resources and Links Sushi Parasite Inspires Worm Test for Cancer – Japanese researchers have discovered that Caenorhabditis elegans worms can detect cancer in people's urine. New Genetic Variant that Causes Autism Identified by Johns Hopkins-Led Team – A Johns Hopkins-led team of researchers has identified a new genetic cause of the disorder using a novel approach that focuses on rare families severely affected by autism. Bad Gene Cripples Flu Defenses – This article describes how a girl nearly died from flu because of mutated genes. High-Fat Diet Alters Behavior and Produces Signs of Brain Inflammation – There is a great possibility that a high-fat diet produces changes in health and behavior, in part, by changing the mix of bacteria in the gut, also known as the gut microbiome. NASA's Opportunity Rover Just Completed an 11-Year Marathon on Mars – NASA confirmed this week that the six-wheeled robot has now traveled more than 26.219 miles in eleven years and two months. Apple's New ResearchKit: 'Ethics Quagmire' or Medical Research Aid? – Apple's ResearchKit is designed to let medical researchers create iPhone apps for their studies that will help them recruit participants — without said participants ever setting foot in the lab. Woolly Mammoth DNA Inserted into Elephant Cells – This article describes the attempt of scientists to bring extinct species back from the grave through a process known as de-extinction. Surprise Finding Heightens Concern over Tiny Bits of Plastic Polluting Our Oceans – A team of scientists’ accidental finding of plastic in the skin of both farmed and wild fish adds to already growing environmental and public health concerns about the plastic particles or microplastics pervading our oceans and waterways. Altering Brain Chemistry Makes Us More Sensitive to Inequality – Researchers find that giving a drug that changes the neurochemical balance in the prefrontal cortex of the brain causes a greater willingness to engage in prosocial behaviors, such as ensuring that resources are divided more equally. Engineering the Perfect Baby – A group of scientists try to edit the DNA of human germ line to correct disease genes and to pass those genetic fixes on to future generations.
