After being diagnosed with a rare and deadly form of malignant melanoma - acral lentiginous melanoma - Dr George McGavin embarks on a highly emotional and deeply personal journey as he goes through treatment for his cancer. George’s treatment is targeted drug therapy, using drugs approved for use by the NHS only weeks before his diagnosis. During this journey, he is given unprecedented access to the process and science behind his medical treatment and diagnosis. He also meets some of the most highly regarded scientists in the field of cancer research in his quest to understand not just his disease but what the future holds as a whole for cancer treatment. Amongst them are Professor Sir Michael Stratton, director of the Wellcome Sanger Institute and chief executive officer of the Wellcome Genome Campus, whose work resulted in the discovery of the mutation in the B RAF gene responsible for his form of melanoma. George also travels to Houston, Texas to meet Professor James P Allison, winner of the 2018 Nobel Prize in Medicine, to find out about his pioneering work in the field of immunotherapy - the greatest breakthrough in cancer research in a century. Back home in his own hospital, he meets a unique group of stage four melanoma patients who owe their lives to Professor Allison’s work. Ultimately, his journey culminates when he receives his prognosis, after three months of treatment, which will determine his future. Will these groundbreaking drugs actually work?

Chocolate reduces stress. Fish stimulates the brain. Is there any truth to such popular beliefs? The findings of researchers around the world say yes: It appears we really are what we eat. A study in a British prison found that inmates who took vitamin supplements were less prone to violent behavior. And in Germany, a psychologist at the University of Lübeck has shown that social behavior is influenced by the ingredients consumed at breakfast. But what really happens in the brain when we opt for honey instead of jam, and fish rather than sausage? Scientists around the world are trying to find out. Neuro-nutrition is the name of an interdisciplinary research field that investigates the impact of nutrition on brain health. Experiments on rats and flies offer new insight into the effects of our eating habits. When laboratory rats are fed a diet of junk food, the result is not just obesity. The menu also has a direct influence on their memory performance. The role of the intestinal flora has been known for some time, but scientists are currently discovering other relationships. So-called "brain food" for example: The Mediterranean diet that’s based on vegetables and fish is said to provide the best nutrition for small grey cells. Omega-3 fatty acids, which are found in fish, for example, protect the nerve cells and are indispensable for the development of the brain - because the brain is also what it eats!

Youth may be wasted on the young, but luckily, you can buy it back. People are using everything from face-lifts to second skin tech to keep their youthful advantage. However, with so many unproven therapies on the market, how many actually work?
Many clinical trials target the nation's most acute health issues. With deaths from liver disease soaring by 40 per cent in a decade, more and more patients are waiting for vital liver transplants. There is a shortage of organ donors and many donated organs are rejected as only those in excellent condition are considered suitable for a transplant procedure. Surgeons Richard Laing and Thamara Perera are part of a team at QEHB trialling a revolutionary way to tackle this crisis, by maximising the number of donor organs that can be safely re-used. The film follows the trial every step of the way, as Richard receives a donor liver that would usually be rejected and tries to prove it is viable for transplant by rejuvenating and testing it on a perfusion machine. This machine sustains the liver by mimicking the supply of blood, oxygen and nutrients an organ receives inside a live, healthy human body. Once the donor liver has proved itself fit for transplant, the surgical team start to remove grandmother Connie O'Driscoll's severely diseased liver. Once the donor liver has been disconnected from the perfusion machine, they have just 20 minutes to place it in Connie's body and plumb it into the complex and delicate network of hepatic blood vessels.
