The use of embryonic stem cells has ignited fierce debate across the spiritual and political spectrum. But what if we could create manmade stem cells - or find super cells in adults that could forever replace embryonic cells and remove the controversy? Today, we are on the brink of a new era - an age where we may be able to cure our bodies of any illness. Stephen Hawking has spent his life exploring the mysteries of the cosmos, now there is another universe that fascinates him - the one hidden inside our bodies - our own personal galaxies of cells. Hawking takes us on a fascinating journey exploring what these wondrous and baffling mechanisms are capable of. He is joined by the scientists who are on the front lines of discovery in this field including Dr. Doris Taylor who is customizing a donor's heart with the recipient's stem cells - her goal is to revolutionize heart transplants, Dr. Paul Lu and Dr. Mark Tuszynski may have created a breakthrough that could cure paralysis, and Dr. Vincent Giampapa who believes that stem cells can be used to stem the tide of aging and create a fountain of youth.
Fewer children in the United States are getting vaccinated. That’s bad news for those kids, and also for public health in general. Often, the response is to argue and debate and get angry at people who are we see as making terrible, irrational decisions. Instead of doing that, let’s use science to understand why this is happening in the first place.
The acerbically witty and severely facially disfigured broadcaster Adam Pearson presents a personal film about genetics. He and his twin brother Neil are genetically identical and both share the same genetic disease, Neurofibromatosis 1 (Nf1) - yet they are completely different. Adam's face is covered with growths, whereas Neil has none. Neil has short term memory loss, whereas Adam is razor sharp. How can the same genetic disease affect identical twins so differently? Adam is on the cusp of a successful film and television career, but the disease has left tumours on his face that are growing out of control and he could lose his sight. For years, everyone thought Adam's brother Neil had escaped symptoms, but today his life is governed by epilepsy and a mysterious memory loss that suddenly came on during his teens. Determined to save their future, Adam tries to find out why the disease affects the twins so differently.
NOVA takes you inside the operating room to witness organ transplant teams transferring organs from donors to recipients. Meet families navigating both sides of a transplant, and researchers working to end the organ shortage. Their efforts to understand organ rejection, discover ways to keep organs alive outside the body, and even grow artificial organs with stem cells, could save countless lives.
