History's deadliest colors - J. V. Maranto
AdultsHistoryScienceArtWhen radium was first discovered, its luminous green color inspired people to add it into beauty products and jewelry. It wasn't until much later that we realized that radium's harmful effects outweighed its visual benefits. Unfortunately, radium isn't the only pigment that historically seemed harmless or useful but turned out to be deadly. J. V. Maranto details history's deadliest colors. Lesson by J. V. Maranto, animation by Juan M. Urbina.

How does asthma work? - Christopher E. Gaw
AdultsHealthHumanScienceMore than 300 million people around the world suffer from asthma, and around 250,000 people die from it each year. But why do people get asthma, and how can this disease be deadly? Christopher E. Gaw describes the main symptoms and treatments of asthma.
Why Do We Cook?
AdultsFoodScienceSociety...Why do humans cook? Holidays are celebrated in many ways, but chances are they involve eating, and eating a LOT. Ever wonder why we cook our food? We do it because it tastes good, of course, and because our customs and traditions are built around it. But we also cook our food for some basic biological reasons, because of evolution. Some scientists think that figuring out how to cook actually MADE us human! If conversation gets a little dry around your holiday table, now you'll have some awesome science to share with everyone!

Oxygen's surprisingly complex journey through your body - Enda Butler
AdultsBiologyHumanScience...Oxygen forms about 21% of the air around us. In your body, oxygen forms a vital role in the production of energy in most cells. But if gases can only efficiently diffuse across tiny distances, how does oxygen reach the cells deep inside your body? Enda Butler tracks the surprisingly complex journey of oxygen through your body.
What is entropy? - Jeff Phillips
AdultsPhysicsScienceChemistryThere's a concept that's crucial to chemistry and physics. It helps explain why physical processes go one way and not the other: why ice melts, why cream spreads in coffee, why air leaks out of a punctured tire. It's entropy, and it's notoriously difficult to wrap our heads around. Jeff Phillips gives a crash course on entropy.
