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.
The Ebola virus. No-one knows exactly where it comes from but one thing is certain - it's one of the most virulent infections known to science. This special episode of Horizon meets the scientists and doctors from all around the world looking for the cure and hears first-hand accounts of what it's actually like to catch - and survive - this terrible disease.
Our skin is the largest organ in our bodies, with a surface area of about 20 square feet in adults. When we are cut or wounded, our skin begins to repair itself through a complex, well-coordinated process. Sarthak Sinha takes us past the epidermis and into the dermis to investigate this regenerative response.
Diseases that were largely eradicated in the United States a generation ago—whooping cough, measles, mumps—are returning, in part because nervous parents are skipping their children’s shots. NOVA's "Vaccines—Calling the Shots" takes viewers around the world to track epidemics, explore the science behind vaccinations, hear from parents wrestling with vaccine-related questions, and shed light on the risks of opting out.
Periodontal disease affects more people worldwide than any other illness, according to the Guinness World Records. It destroys gum and bone, eventually causing teeth to fall out. Periodontal disease may also be linked to life-threatening illnesses, such as pneumonia and diabetes. One drawback of standard treatments is that it's difficult to restore damaged tissue. But a drug developed in Japan regenerates gum and bone, and saves teeth. We'll also look at ways to maintain good oral hygiene, even when disaster strikes.
Not all the microbes that live on us or inside us are benign, and it is only thanks to the superhuman nature of our bodies that we survive constant attack. However, humans are becoming increasingly vulnerable to disease. This programme examines the dramatic increase in allergic diseases such as asthma, eczema and hayfever.
