Biology is undergoing a revolution that is radically changing our conception of evolution. Our genes don’t control everything: they can be influenced by fascinating mechanisms recently brought to light by international research teams.
A&E doctor Javid Abdelmoneim is on a mission to find out the truth about alcohol. In January, the government released its new alcohol guidelines. For men, the recommended weekly limit was cut by a third to 14 units per week, equivalent to about seven pints of beer, bringing it in line with the amount recommended for women. So what is behind the change? This is just one question of many that Javid aims to answer as he explores the science of drinking and the new evidence for the health risks of alcohol. Why do some people get drunk quicker than others? What is behind red wine's healthy reputation? Is a nightcap actually good for your sleep? Does lining your stomach work? And can alcohol actually make you eat more?

In the opening episode, they explore how this chemistry fuels and builds our bodies. Michael begins by trying the first meal most of us enjoyed, human breast milk, which contains everything a baby needs - fats, carbs, vitamins and minerals. As we grow, we continue to seek the same chemistry in our diet but from a wide variety of scrumptious fare as Michael and James discover. In San Francisco, they unravel why sourdough bread is so good for us, in the Philippines, they learn how a river weed - rice - has become a comforting staple food, and in Bulgaria, they discover why letting your mushrooms sunbathe may help you get a calcium boost from your dairy food.

The heart is the most symbolic organ of the human body. Throughout history it has been seen as the site of our emotions, the very centre of our being. But modern medicine has come to see the heart as just a pump; a brilliant pump, but nothing more. And we see ourselves as ruled by our heads and not our hearts. In this documentary, filmmaker David Malone asks whether we are right to take this view. He explores the heart's conflicting histories as an emotional symbol and a physical organ, and investigates what the latest science is learning about its structures, its capacities and its role. In the age-old battle of hearts and minds, will these new discoveries alter the balance and allow the heart to reclaim something of its traditional place at the centre of our humanity?
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.
Dr Chris Van Tulleken calls on the British public to seek out the truth about the top-selling over-the-counter medicines. We spend an astonishing 2.3 billion pounds on pills, potions and lotions from the chemist's shop every year to beat common ailments from headaches to colds to indigestion. But how much do we really know about what we're buying?
