| 1 | VideoBytesize Science - The Electronic Nose: Sniffing Out the Dangerous Stuff to Keep Our Noses Safe | In the past decade, our cell phones have evolved into multi-functional, always online digital assistants and gaming devices. Nate Lewis, Professor of Chemistry at Caltech, is working on technology that may turn your next smartphone into a bomb-sniffing, disease-diagnosing "electronic nose." | 5/9/12 | Free | View In iTunes |
| 2 | VideoBytesize Science - The Periodic Table Table Featuring Theo Gray | Some people collect stamps. Wolfram Research co-founder and author Theo Gray collects elements. Step into his office, and you'll see a silicon disc engraved with Homer Simpson, a jar of mercury, uranium shells and hundreds of other chemical artifacts. But his real DIY masterpiece is the world's first "periodic table table." Within this masterfully constructed table-top lay samples of nearly every element known to man, minus the super-radioactive ones. Theo Gray is 2011 winner of the ACS Grady Stack Award for Interpreting Chemistry for the Public. The Periodic Table Table is a testament to Theo's love for chemistry -- as well as his Ebay buying habits -- and is full of fascinating stories. Come see for yourself in the latest episode of Bytesize Science. | 2/22/12 | Free | View In iTunes |
| 3 | VideoChemMatters Video Episode 9 - Digestion: The Incredible Disassembly Line | You could call digestion a disassembly line. Your body takes whatever morsel of food you give it, breaks it down, wrings out all the nutrients it can, and discards the waste. It's an amazing example of chemistry in action, and it happens 24/7. Our body relies on three major types of food: carbohydrates, fats and proteins. In this latest episode of ChemMatters, find out how the body breaks down these big three food groups and puts their nutrients to use. | 2/10/12 | Free | View In iTunes |
| 4 | VideoBytesize Science - Super Bowl Sunday Science: The Chemistry of Cheese | This Sunday, an estimated 58 percent of Americans will order pizza for Super Bowl parties around the country. To celebrate Game Day classics like pizza, cheese dips and nachos, we went to Wisconsin -- the American dairyland that produces 35 percent of the country's cheese -- to find out the chemistry behind cheesemaking. Featured in the video is John Lucey, Ph.D., director of the Center for Dairy Research at the University of Wisconsin-Madison. Lucey explains how food scientists use analytical chemistry techniques to test the levels of fat, protein and flavor compounds in cheese to ensure a tasty, nutritious product. Like the New England Patriots and New York Giants teams on the TV screen, cheese also has to pass "performance tests" — not for its time on the 40-yard dash, but to ensure that cheese has the perfect amount of melt and stretch for those Super Bowl XLVI pizzas and other treats. | 2/1/12 | Free | View In iTunes |
| 5 | VideoBytesize Science - Phytochemicals: Why You Should Eat A Rainbow of Fruits and Veggies | Phytochemicals, or plant chemicals, are found in a wide variety of fruits and vegetables, each one with an associated color.

Episode 2: Fake Snow | Take fake snow for an example. One of the paradoxes of fake snow is that it is better than the real thing. According to Richard Rickitt, author of Special Effects: The History and Technique, once snow is trampled, it can’t be restored, so snow shots can be repeated just once or twice, after which a movie crew needs to move to a new location.
