The Science of Sleep: How To Sleep Better

The British Sleep Council says that 70 per cent of people in the UK do no get enough sleep. Gaby Roslin and Amir Khan present the first of two programmes in which they aim to put things right, applying the latest science to some of the worst sleepers. They include a sleep deprivation experiment, as well as help for an extreme snorer and a man who suffers from night terrors. A woman who has restless leg syndrome, and a man who has had chronic insomnia for 20 years. The sleep deprivation experiment continues, setting up a mini casino to test for risky behaviour, pain resistance and emotional control. Finally, as the subjects reach the final hours of the challenge, the experiment begins to take its toll as the participants' emotions go into overdrive, with one threatening to quit altogether.

Black Hole Hunters

Astronomer Shep Doeleman and his team are on a mission that will challenge the theories of Albert Einstein and could pave the way to a revolution in physics: to capture the first-ever image of a black hole. To do this, they must link eight multimillion-dollar observatories around the world to a spot 26,000 light years away. It's the equivalent of spotting an orange on the moon, but after 10 years of planning and the combined brainpower of over 200 international scientists, the team feels they're ready to make scientific history.

The Allies Strike Back/Twilight of the Axis

Examines the botched raid on the German-occupied harbour of Dieppe, France in August 1942, which resulted in the loss of around 4,000 Allied men and drove home just how costly an invasion of France would be. The programme also focuses on Hitler's order in 1945 to destroy any military or industrial facilities that could be useful to the enemy - which would have condemned the German people to utter desolation.

The Road to Stalingrad/Leviathan Wakes

A look at how Hitler calculated that to fight on long enough to fulfil his aim of eradicating Europe's Jews he needed to capture the Caucasus, and to do that he had to take Stalingrad. There is also a look at how the US rebuilt its navy and took itself from the 18th-ranked army in the world to be second only to the Soviet Union, a tale of ingenuity and enterprise that turned the vast resources of America into the numbers that could win a war.

Part 4

D-Day is a success, but now the Allies face the challenge of breaking out of the dense hedgerows of Normandy and into open country. They face highly motivated and experienced German soldiers, including Waffen SS units, who make them pay dearly for every yard they advance. The savagery of the fighting also takes a high psychological toll on Allied soldiers – much more so than on German troops who have been subjected to years of indoctrination. But in the end, Allied material superiority takes its toll. General Patton arrives to lead the charge into open country. German soldiers start to surrender in ever greater numbers, and the road to Paris is suddenly open.

Part 3

D-Day is underway, but at Omaha Beach, 'the Bedford Boys', volunteers of the US 29th Infantry Division, find themselves thrown into freezing surf and a murderous German cross-fire. As the first assault waves are mown down on the ramps of their landing craft, it looks like the Allied invasion of Europe might be careering towards disaster. But at other beaches the British, Canadian and US troops are soon able to advance inland. For the local French population it is a moment of joy, but also great danger. Hundreds are killed when the RAF bombs the Norman town of Caen – one of their D-Day objectives. The fighting inland is no less fierce than on the beaches. As 'the Longest Day' draws to a close, rumours circulate on both sides that the enemy is shooting its prisoners.

Part 2

D-Day suffers a last minute postponement when the weather over the Channel deteriorates. For Allied Supreme Commander General Eisenhower these are moments of extreme anxiety. Many of his men will be experiencing combat for the first time, and there is much that could go wrong. When meteorologists promise Eisenhower a brief window of improved weather, he takes the gamble and orders the invasion to proceed. Airborne divisions lead the way, parachuting into the darkness over Normandy. Shortly after dawn landing craft approach the coast. At Omaha Beach the Germans are waiting for them. The carnage that follows is described here with vivid personal testimony from both sides.

2/4D-Day: The Soldiers Story • 2012 • History

Part 1

In 1943 the British and Americans plan the opening of a 'Second Front' in Northwest Europe. Huge numbers of troops, aircraft and ships begin to assemble in England for the invasion of France. They train relentlessly for what will prove the largest amphibious operation in military history. Meanwhile across the Channel the Germans also gather their strength. Hitler sends one of his best generals, 'the Desert Fox' himself Field Marshal Erwin Rommel, to supervise the construction of coastal defences known as 'the Atlantic Wall'. But the Allies retain one crucial advantage that even Rommel's genius cannot compensate for – only the Allies know where and when they will strike.
