    Chris Toumazou on inventing medical devices
    European Inventor of the Year, Chris Toumazou, reveals how his personal life and early research lie at the heart of his inventions.As Chief Scientist at the Institute of Biomedical Engineering at Imperial College London, Chris inspires engineers, doctors and other scientists to create medical devices for the 21st century.Applying silicon chip technology, more commonly found inside mobile phones, he tackles seemingly insurmountable problems in medicine to create devices that bridge the electronic and biological worlds - from a digital plaster that monitors a patient's vital signs to an artificial pancreas to treat diabetes.His latest creation, coined a 'lab on a chip', analyses a person's DNA within minutes outside the laboratory. The hand-held device can identify genetic differences which dictate a person's susceptibility to hereditary diseases and how they will react to a drug like warfarin, used to treat blood clots.Producer: Beth Eastwood.

    Elspeth Garman on crystallography
    Jim al-Khalili talks to Professor Elspeth Garman about a technique that's led to 28 Nobel Prizes in the last century.X- ray crystallography, now celebrating its 100th anniversary, is used to study the internal structure of matter. It may sound rather arcane but it's the reason we now know the structure of hugely important molecules, like penicillin, insulin and DNA. But while other scientists scoop up prizes for cracking chemical structures, Elspeth works away behind the scenes, (more cameraman than Hollywood star), improving the methods and techniques used by everybody working in the field. If only it was as simple as putting a crystal in the machine and printing off the results. Growing a single crystal of an enzyme that gives TB its longevity took Elspeth's team no less than fifteen years. No pressure there then when harvesting that precious commodity.

    Jackie Akhavan on explosives
    Jackie Akhavan, Professor of Explosive Chemistry, tells Jim al-Khalili all about the science of explosives. She explains exactly what explosives are and how to make them safer to handle.She started by working on how to make fireworks safer and has been involved in research with bees to see whether they can be used smell different types of explosives. Her current project involves testing the rocket fuel that will be used in Bloodhound, the British designed and built supersonic car that aims to reach a speed of 1,000mph.Her work involves finding out how to best detect explosives in airports and elsewhere, teaching security professionals how to differentiate between false alarms and the real thing. She also works on explosives used in warfare and discusses the ethical issues involved.Producer: Melissa Hogenboom.

    Brian Cox on quantum mechanics
    Professor Brian Cox of Manchester University describes how he gave up appearing on Top of the Pops to study quarks, quasars and quantum mechanics. Although he describes himself as a simple-minded Northern bloke, he has acquired an almost God-like status on our TV screens; while the 'Cox effect' is thought to explain the significant boost to university admissions to read physics. He talks to Jim Al-Khalili about learning to be famous, his passion for physics and how he sometimes has difficulty crossing the road. In 2005 Brian was awarded a Royal Society Research Fellowship for his work on high energy particle collisions at CERN and elsewhere - an enviable academic achievement. In 2009, he was voted one of the sexiest men alive by People magazine. He has invented a new kind of celebrity - a scientist who's regularly snapped by the paparazzi.Brian wants everyone to be as excited as he is about the laws that govern our universe: the beautiful, counter-intuitive and often weird world of quantum mechanics that explains what happens inside the nucleus of every atom, right down at the level of those exotically named elementary particles - quarks, neutrinos, gluons, muons. Challenged by Jim to explain the rules of quantum mechanics in just a minute, Brian succeeds; while conceding that the idea that everything is inherently probabilistic, is challenging. Even Einstein found it difficult. Schrodinger's cat, or Brian Cox, for that matter, are simultaneously both dead and alive. That's a fact. What this is all means is another question. "Am I just an algorithm?" Brian asks. "Probably", says Jim. Producer: Anna Buckley.
