How do cancer cells grow? How does chemotherapy fight cancer (and cause negative side effects)? The answers lie in cell division. George Zaidan explains how rapid cell division is cancer's "strength" -- and also its weakness.

Because of the way genetic reprogramming works, it’s hard to make one clone based on an adult cell, and it’s almost impossible to make a second-generation one.

Explore the cell cycle with the Amoeba Sisters and an important example of when it is not controlled: cancer. Table of Contents: 00:00 Intro 1:00 Cell Growth and Cell Reproduction 1:42 Cancer (explaining uncontrolled cell growth) 3:27...

Hank hates death, so he helps us understand the process of aging, informs us of how scientists are studying ways to prevent it and brings us the exciting news of current research in longevity... for mice.

Nothing is guaranteed in life except death, taxes, and entropy. What do other life forms have to teach us about staying alive as we get old, and will we ever conquer death?

Learn how scientists are fighting cancer... with algae!
