Scientific American Frontiers Season 10 Episode 3 Never Say Die

In the third episode of season 10 of Scientific American Frontiers, titled "Never Say Die," host Alan Alda explores the latest advances in medical technology and research that are helping people overcome some of the most deadly diseases and injuries.

The episode begins by examining the use of stem cells in repairing damaged tissues and organs, such as in the case of spinal cord injuries. Alda meets with a patient who was left paralyzed after a motorcycle accident, but was able to regain some movement and feeling in his legs through a stem cell treatment. Scientists explain how these cells can be used to regenerate damaged nerve cells, offering hope to those who have been told that their injuries are irreversible.

Next, the show looks at the practice of cryonics, in which bodies are frozen after death in the hopes that they can one day be revived and brought back to life. Alda interviews advocates of cryonics, as well as skeptics who argue that the process is unlikely to ever succeed. He also visits a cryonics facility to see how the bodies are prepared and stored.

The episode then turns to the topic of cancer, exploring some of the latest treatments that are being used to combat this deadly disease. Alda meets with a woman who received a personalized vaccine against her cancer, as well as researchers who are creating new immunotherapies that target cancer cells specifically. They discuss the challenges of developing these treatments, as well as the hope that they offer for patients who previously had few options.

Finally, the show looks at the field of regenerative medicine, in which tissues and organs are grown in the lab for transplant into patients. Alda meets with researchers who are using 3D printing to create replacement organs, as well as those who are growing skin for burn victims and cartilage for arthritis patients. They discuss the potential benefits of these advances, as well as the ethical considerations that must be taken into account.

Throughout the episode, Alda reflects on his own experiences with mortality and the ways in which science and technology are changing our understanding of death and disease. The show offers a wide-ranging look at some of the most promising developments in medical research, and highlights the ways in which science is helping people to live longer, healthier lives.
