The Ebola outbreak of 2014 almost brought the world to its knees, but this crisis has mobilized scientists and researchers, paving the way for new treatments and vaccines. From antibiotics and vaccines to computer programs that predict how viruses will spread, new lifesaving tools will be used to fight a wide range of viruses in the near future, including HIV, influenza, dengue fever, malaria, and a host of other killer diseases.

This time, we meet a man who feels no pain, a woman who can smell Parkinson's disease, a man who can remember every face he has ever seen and a survivor of a head injury who woke up to find he could suddenly play the piano.

Fresh or processed, white or red - how does meat measure up? It's been getting a lot of bad press recently with new links to cancer and heart disease. But 98 per cent of us in the UK are still meat eaters. Chris Bavin, a greengrocer by trade and a carnivore by nature, wants to know if he can keep meat in his diet and stay healthy. He teams up with top scientists to put meat under the microscope and examine it as never before. They follow 40 volunteers on a groundbreaking study to find out exactly how much meat is good for us, test whether paying more for chicken makes it any better for us, discover a way to dramatically reduce the health risks associated with processed meats and reveal an unlikely lean supermeat that won't break the bank.
