HPV isn't the only virus that causes cancer, but it's one of the best at it. Here's what we've learned about this supervillain of a pathogen, and how to stop it.

Until now, researchers have assumed that healthy cells switch off the enzyme telomerase as a way to protect themselves from turning cancerous. But a new study suggests the enzyme may have a healthier role than we previously thought....

We all know turtles live an amazingly long time, but what's their secret? And can we apply it to humans?

Hank brings us the story of Elizabeth Blackburn, the Nobel Prize-winning Australian woman who discovered telomeres and telomerase, and helped scientists begin to understand the process of aging at a genetic level.

We all know turtles live an amazingly long time, but what's their secret? And can we apply it to humans?

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?

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.

Here we discuss shortening of telomeres, factors that affect this phenomenon, and the function of telomerase.<br/>
