By the middle of January many people struggle to keep up their resolutions to be more active. The result is that the UK wastes nearly £600 million a year on unused gym memberships. But new science has the answers. Medical journalist Michael Mosley teams up with scientists whose latest research is turning common knowledge about fitness on its head. They reveal why 10,000 steps is just a marketing ploy and that two minutes of exercise is all a person needs each week. They discover how to get people to stick to their fitness plans and what exercise can actually make everyone more intelligent. Whether it is for couch potatoes who hate the thought of exercise, someone too busy to consider the gym, or even for fitness fanatics who are desperate to do more - science can help everyone exercise better.

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.
By 2050 the world’s population is estimated to reach over 9 billion, 30% larger than it currently is. If we continue to farm and eat the way we do today, we’d potentially need an additional landmass the size of Europe to produce enough food to meet the growing demand. So what does the future of food look like and how will we grow enough food for us all to eat in the years to come? In Tonight’s programme we visit some of the urban ventures that are maximising the use of public space to grow fruit and vegetables and teach the next generation how to farm. We speak to the owner of an indoor miniature farm housed inside a small shop about the new aquaponic technology he uses, and we go 100 feet below ground to see how one entrepreneur is growing high-value salad crops in old WWII bomb shelters, four storeys beneath the London Underground!
Dr Chris van Tulleken, Dr Hannah Fry and Michael Mosley examine the latest research and explore some of the big questions about Covid-19 and the pandemic it has created. Michael visits the UK government's high-security laboratory Porton Down, where vaccines are being tested. He also uncovers what the experience of the 2002 SARs epidemic reveals about this one. Both were caused by coronaviruses, but certain key changes to today's virus have allowed it to infect the world, where SARs was contained.
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.
