"My ideas are often labelled as impossible, or useless, or both. Usually when people say that I'm on the right track."George Church is a geneticist, molecular engineer, and one of the pioneers of modern genomics. He's also someone who makes a habit of finding solutions to the seemingly impossible.Over the course of his career so far, George developed the first method for direct genomic sequencing, helped initiate the Human Genome Project, and founded the Personal Genome Project: making huge quantities of DNA data publicly available for research. Today, as a professor at Harvard Medical School and MIT, he’s working on some of the most headline-grabbing - and controversial - science on the planet: from the so-called "de-extinction" of woolly mammoths, to growing transplant-suitable organs in pigs, to virus-proofing humans.When inspiration strikes, there seems to be little that will slow him down - even the fact that he has narcolepsy, the neurological disorder that causes sudden sleep attacks. In fact, as George tells Professor Jim Al-Khalili, some of his best ideas come in those moments between waking and sleep...Presented by Jim Al-Khalili Produced by Lucy Taylor for BBC Studios

Movies might have us believe that bomb disposal comes down to cutting the right wire. In fact, explosive devices are complex and varied - and learning how to dispose of them safely involves intense training, as well as the ability to stay calm under pressure. This was the world of Dr Gareth Collett, a retired British Army Brigadier General and engineer, specialising in bomb disposal; whose 32-year military career took him around the world, including heading up major ordnance clearance projects in Iraq and Afghanistan. After retiring from the army, Gareth became a university lecturer – but following his diagnosis with bladder cancer, started researching a possible link between bomb disposal veterans and higher rates of urological cancers.In conversation with Professor Jim Al-Khalili, Gareth discusses this ongoing research, dealing with PTSD - and why he just can't watch Oscar-winning movie The Hurt Locker...Presented by Jim Al-Khalili Produced by Lucy Taylor for BBC Studios

Many people will be familiar with Parkinson’s disease: the progressive brain disorder that causes symptoms including tremors and slower movement, leading on to serious cognitive problems. You might not know that it’s the fastest-growing neurological condition in the world. Today it affects around 11.8 million people and that’s forecast to double by 2030. Dr Sonia Gandhi is one of the scientists working to change that trend. As Professor of Neurology at University College London and Assistant Research Director at the Francis Crick Institute, her work involves using stem cells to build models of the human brain, helping to drive the development of drugs and other therapies for Parkinson’s patients.Talking to Professor Jim Al-Khalili, Sonia explains why this destructive condition is on the rise - and the promising routes they're studying to find new ways to tackle it.Presented by Jim Al-Khalili Produced by Lucy Taylor for BBC StudiosFor details of organisations that offer advice and support to anyone affected by Parkinson's Disease, please go online to bbc.co.uk/actionline.
