About this episode
The long rains of East Africa are forecast to fail again, for the third year running, precipitating a food crisis affecting millions. Science In Action explores the science of the drought, hears about new methods improving forecasts, and what is unusual about the region that makes it so vulnerable.
When we think of helium, for many of us balloons and squeaky voices come to mind. But the noble gas is critical for many aspects of modern life – and we’re facing a global shortage.
