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
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.

Here are some of the symptoms associated with not drinking enough water...
Why do animals have such different lifespans? - Joao Pedro de Magalhaes
AdultsAnimalsLifeNature...For the microscopic lab worm C. elegans, life equates to just a few short weeks on Earth. The bowhead whale, on the other hand, can live over two hundred years. Why are these lifespans so different? And what does it really mean to 'age' anyway? Joao Pedro de Magalhaes explains why the pace of aging varies greatly across animals.
The three different ways mammals give birth - Kate Slabosky
AdultsAnimalsNatureBiology...All mammals share certain characteristics, like warm blood and backbones. But despite their similarities, these creatures also have many biological differences - and one of the most remarkable differences is how they give birth. Kate Slabosky details the placental, marsupial, and monotreme methods of giving birth.
