Scientific American Frontiers Season 11 Episode 7 The Bionic Body

Scientific American Frontiers season 11 episode 7, titled "The Bionic Body," explores the ways in which advances in technology are allowing us to improve and augment the human body like never before.

Host Alan Alda first speaks with researchers who are developing prosthetics that not only replace lost limbs but also provide a sense of touch and even allow for movement through thoughts alone. These bionic limbs are changing the lives of amputees, allowing them to do things they never thought possible and feel more integrated into society.

Next, Alda visits the lab of a scientist who is exploring the potential uses of exoskeletons — wearable robotic devices that can aid in movement. From helping soldiers carry heavy loads to providing assistance to those with mobility issues, exoskeletons have the potential to significantly improve our physical capabilities.

The episode also delves into the science of brain-machine interfaces, where electrodes implanted in the brain can allow people to control external devices with their thoughts. This technology has the potential to help those with paralysis regain some level of independence and control over their environment.

Alda speaks with a woman who underwent a cutting-edge treatment for her paralysis, which involved the implantation of an electrode in her brain. Though the procedure is not without its risks, the woman was able to use her thoughts to control a robotic arm and complete tasks she never thought she would be able to do again.

In addition to these technological advancements, "The Bionic Body" also explores the cutting-edge field of regenerative medicine. Alda visits a lab where researchers are using 3D printing technology to create replacement organs that could one day eliminate the need for organ donors.

Finally, the episode takes a look at a new form of therapy known as transcranial magnetic stimulation, or TMS. This treatment involves the use of electromagnetic fields to stimulate specific areas of the brain and has shown promise in treating everything from depression to addiction.

"The Bionic Body" is a fascinating exploration of the ways in which technology is helping us push the boundaries of what the human body is capable of. From prosthetics that can provide a sense of touch to replacement organs created through 3D printing, the potential for new advancements is unlimited.
