In the third episode of the second season of NOVA scienceNOW, the show explores several fascinating topics related to aging, space exploration, ancient Maya civilization, and the work of microbiologist Bonnie Bassler.

The first segment of the episode focuses on the science of aging and the quest to understand and possibly extend human life. The host, Neil deGrasse Tyson, talks to scientists who are studying various aspects of aging, from telomere length to caloric restriction to pharmaceutical interventions. The segment also looks at the personal experiences of individuals who are approaching or have exceeded 100 years of age and how they view aging and longevity.

The second segment of the episode delves into the concept of a space elevator, a hypothetical structure that would allow us to transport people and cargo from Earth to space much more efficiently than current methods. Tyson speaks with engineers and scientists who are working on the science and engineering challenges of building such a structure, which would require a cable that stretches from Earth's surface to geostationary orbit. The segment also looks at the possible economic and environmental benefits of a space elevator.

The third segment of the episode switches gears to focus on the ancient Maya civilization and the recent discovery of a major archaeological site in Guatemala.
