Welcome to episode 30, what a great show we have for everyone. As always we dive right into the literature in our science roundup. In the round up we discuss a range of topics including, a paralyzed man walks again, a stem cell box office hit, intestines generated from stem cells, sugary drinks and telomeres, legislation to help young scientists, and many more. Then we welcome on a Nobel Prize winning scientist, Dr. Harold Varmus. We talk with Dr. Varmus about a range of topics in the realm of biomedical research as a career and the state of NIH funding. What an honor and a great interview, we hope you enjoy it as much as we did. Then we end the show ranting about the new iPhones. ENJOY!

Human Genetic Research Uncovers How Omega-6 Fatty Acids Lower Bad Cholesterol – This article reveals how researchers have uncovered a gene that affects blood cholesterol levels through the generation of a compound from omega-6 polyunsaturated fatty acids, called lipoxins.
Are Male Brains Wired to Ignore Food for Sex? – This article describes how male C. elegans, a microscopic roundworm that is widely used in studying fundamental mechanisms in biology suppresses their ability to locate food in order to instead focus on finding a mate.
Ultra-Fast Charging Batteries That Can Be 70% Recharged In Just Two Minutes – This article reveals how scientists from Nanyang Technological University have developed a new battery that can be recharged up to 70% in only 2 minutes and also have a longer lifespan of over 20 years.
Stem-Cell Fraud Makes For Box Office Success – This article is about how the movie, Whistleblower, which was based on the Woo Suk Hwang cloning scandal, has been a box office hit in South Korea.
Stem Cells For Diabetes: The Danger Of The Word ‘Cure’ – This article tries to discuss about danger in loosely using the word ‘cure’ as it falsely raises hopes and expectations of patients and other people.
Paralyzed Man Walks After Nose Cells Placed In Spine – In this article, a man paralyzed from the chest down in a knife attack is walking again after undergoing surgery using cells responsible for the sense of smell, marking an advance in the search for treatments for spinal injuries.
Paralyzed Walk–Without Embryonic Stem Cells! – This article tries to emphasize that the paralyze man was able to walk after the transplant of his own olfactory cells instead of embryonic stem cells.
Stem Cells Seem Safe in Treating Eye Disease – This article discusses the study conducted by scientists on a treatment based on embryonic stem cells that seem safe and might help restore vision for people with macular degeneration and macular dystrophy.
UCSD Announces Human Testing Of Stem Cell Treatment Underway – In this article, UC San Diego Health System announced that human testing of injected neural stem cell therapies are underway at its Sanford Stem Cell Clinical Center.
Young, Brilliant and Underfunded – This article emphasizes the need for National Institutes of Health to fund young, good researchers who are doing valuable work in the prime of their careers.
Updated: Fountain Of Youth: A Congressman’s Plan To Make NIH Grantees Younger – This article is about the a member of Congress who plans to order National Institutes of Health (NIH) to bring down the average age at which new investigators receive their first grant by 4 years within a decade.
Spare Parts For People? Stem Cell-Generated Human Intestine Grown In Lab Mouse – In this article, researchers have successfully transplanted functioning human intestinal tissue grown from stem cells into mice and could potentially revolutionize the production of spare organs for people, using cells from their own bodies.
MSC-Regulated MicroRNAs Converge on the Transcription Factor FOXP2 and Promote Breast Cancer Metastasis – This article explains how mesenchymal stem/stromal cells (MSCs) cause aberrant expression of microRNAs led by microRNA-199a provide breast cancer cells with enhanced cancer stem cell properties.
Generation Of The Epicardial Lineage From Human Pluripotent Stem Cells – This article identifies BMP and WNT as key regulators of the epicardial lineage in vitro and providing a model for investigating epicardial function in human development and disease.
Differentiation Of Human Pluripotent Stem Cells To Cells Similar To Cord-Blood Endothelial Colony–Forming Cells – This article tries to differentiate human pluripotent stem cells into endothelial cells with properties of cord-blood endothelial colony-forming cells that may enable the derivation of clinically relevant numbers of highly proliferative blood vessel–forming cells to restore endothelial function in patients with vascular disease.
