History's deadliest colors - J. V. Maranto

AdultsHistoryScienceArt
When 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.

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!

What humans will look like in 1,000 years

AdultsFutureHumanScience...
There will eventually be a day where prosthetics are no longer just for the disabled. However, it's not just our outside appearance that will change - our genes will also evolve on microscopic levels to aid our survival. For example, an Oxford-led study discovered a group of HIV-infected children in South Africa living healthy lives. It turns out, they have a built-in defense against HIV that prevents the virus from advancing to AIDS.

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

AdultsPhysicsScienceChemistry
There'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.
