Bang Goes The Theory sees Dallas Campbell, Liz Bonnin, Jem Stansfield and Dr Yan Wong coming up with ingenious ways of explaining the latest developments in technology.
Hurricanes, floods, earthquakes, wars - all can trigger not just thousands of casualties and refugees, but also a worldwide humanitarian effort, with the roots for its success founded in science. At the Zaatari refugee camp, temporary home to around 20,000 Syrians, Maggie Philbin looks at the problems the humanitarian community faces when tackling a disaster, and how the lessons learned there might help closer to home. Liz Bonnin comes face to face with cholera, one of the most feared bacteria on the planet. And the team are joined by Dr Chris Van Tulleken, who makes Plumpy'nut, a simple peanut-based paste that has saved tens of thousands of famine victims.
HS2 may be the most exciting news in the world of railways, but by the time it is built the existing system may well have to cope with twice the number of passengers it does today. The team look at the many measures engineers are taking to ensure Britain's ageing rail system stays on track. Liz Bonnin looks at how signals may disappear from the trackside and how hearing impairment could be one of the biggest killers on the railway lines. Meanwhile, Maggie Philbin looks at how a train travelling at 125 mph is set to revolutionise trackside maintenance.
