Ethics and Advances in Stem Cell Research

Guest: Dr. Rhonda Newman to talk about her work in trying to figure out a better way to "de-stress" stem cells. Resources and Links Previously Unknown Effect of Vitamin A Identified – A previously unknown effect of vitamin A in human embryonic development has been identified by researchers, indicating that vitamin A affects the formation of blood cells. Feeding Babies Foods with Peanuts Appears to Prevent Allergies – Researchers found that babies who consumed the equivalent of about 4 heaping teaspoons of peanut butter each week, starting when they were between 4 and 11 months old, were about 80 percent less likely to develop a peanut allergy by age 5. Mothers Can Pass Traits to Offspring through Bacteria’s DNA – Mothers can pass a trait to their offspring through the DNA of bacteria suggesting that microbes may play a significant role in how genes influence illness and health in higher organisms. Kids, Allergies and a Possible Downside to Squeaky Clean Dishes – This article reports that in families who said they mostly wash dishes by hand, significantly fewer children had eczema, and somewhat fewer had either asthma or hay fever, compared to kids from families who let machines wash their dishes. Scientists Unveil Map of 'Epigenome,' a Second Genetic Code – Scientists for the first time have mapped out the molecular "switches" that can turn on or silence individual genes in the DNA in more than 100 types of human cells, an accomplishment that reveals the complexity of genetic information and the challenges of interpreting it. Ingredient in Olive Oil Looks Promising in the Fight Against Cancer – A Rutgers nutritional scientist and two cancer biologists at New York City’s Hunter College have found that an ingredient in extra-virgin olive oil called oleocanthal kills a variety of human cancer cells without harming healthy cells. Popular Soda Ingredient Poses Cancer Risk to Consumers – Research analysis suggests that soda drinkers consume one or more cans per day—possibly exposing them to 4-methylimidazole, a potential carcinogen formed during the manufacture of some kinds of caramel color. Amyloid Formation May Link Alzheimer Disease and Type 2 Diabetes – This article tries to investigate the processes underlying amyloidosis that link type 2 diabetes mellitus and Alzheimer disease. Stopping HIV with an Artificial Protein – A research team has shown that a lab-made molecule eCD4-Ig that mimics an antibody from our immune system may have more protective power than anything the body produces, keeping four monkeys free of HIV infection despite injection of large doses of the virus. Mulling the Marijuana Munchies: How the Brain Flips the Hunger Switch – This article shows that the "munchies," or that uncontrollable urge to eat after using marijuana, appear to be driven by neurons in the brain that are normally involved in suppressing appetite, according to a new study by Yale School of Medicine researchers. Oocytes and Obesity – Eggs from excessively overweight mothers suffer mitochondrial damage that can be averted with pharmacological intervention. Nitrogen-Fixing Bacterium Could Cut Biofuel Costs – This article reports that ethanol-producing Zymomonas mobilis can live on nitrogen gas, potentially cutting costs and environmental waste in biofuel production. Long-Lived Immunotherapy Stem Cells – The genetically modified T memory stem cells persist in patients for more than ten years, and can differentiate into a variety of T cell types. Clarkson University, SUNY Plattsburgh Researchers Use Saliva Test to Diagnose Autism – A spit test may one day be able to diagnose autism as reported by the researchers at Clarkson University and the State University of New York at Plattsburgh. Alligator Blood May Provide Basis of Wartime Anti-Infectives – A study conducted by a group of researchers in the School of Systems Biology and the National Center for Biodefense and Infectious Diseases on alligators,
