Guest Alfred Thompson from Microsoft describes how the new XBox Kinect works. Also, we will learn about a blast detector badge being developed for soldiers.
Addicted to Chocolate?
I love chocolate, but am I addicted to it? Harvard graduate student Naveen Sinha talks about the science of chocolate. Also, Dr. Ashley Gearhardt discusses the new issue of food addiction.
Two Ways to Study Disease: GFP and Epigenetics
Today we will hear about two different ways to study disease. The first is using GFP, for which the discovery and use of won the 2008 Nobel Prize for Chemistry. Then we will learn about how epigenetics, the study of gene expression, is used in cancer research.
Python Hearts | Safety of Nanotechnology
After a python eats a very large meal, its heart can grow significantly larger. Find out how we may be able to use that information to help human hearts. Also, while nanotechnology is quickly growing in importance, many researchers are determining ways to make it as safe yet effective as possible.
Fighting Cancer with Salmonella | Tracking Wastewater with Sweeteners
Find out how Salmonella cells may be able to fight cancer in a unique two wave attack. Also, learn how artificial sweeteners can be used to track the migration of wastewater after release into the environment.
Stem Cell Targeting | Genetics of Sleep
Discover how scientists can use nanomagnets to direct stem cells to injured locations in the body. Then learn how genetics can play a role in how we sleep.
Earthquakes in New England | Nano Sized Medicine
Learn about the recent 5.8 magnitude earthquake in Virginia that was felt all the way up in Boston. Also, Dr. Jim Wilking from Harvard University talks about his research into developing very tiny pharmaceuticals.
Measures of Melting | Green Batteries
The ice sheets in Greenland and Antarctica are constantly changing. In the first part of this podcast, find out how this happens and how scientists are measuring these changes. Then, learn about a type of algae that could significantly improve our current battery technology.
Let's Play Ball! | Building a Cooler Transistor
Physicist Dr. Alan Nathan from University of Illinois talks about some of the physics of baseball. We will also learn about a new nano-material that may keep computer transistors cooler.
Jupiter Collision | Using Ivy in Sunscreen
Discover how during the formation of our solar system, Jupiter may have been involved in a massive collision which has forever altered it. Switching from the very large to the very small, hear about ivy-based nanoparticles that may be used to make a better sunscreen.
