The film reveals the secret story behind one of the greatest intellectual feats of World War II, a feat that gave birth to the digital age.
In 1943 Bill Tutte, a 24-year-old maths student and a GPO engineer called Tommy Flowers combined to hack into Hitler's personal super code machine - not Enigma but an even tougher system, which he called his 'secrets writer'. Their break turned the Battle of Kursk, powered the D-day landings and orchestrated the end of the conflict in Europe. But it was also to be used during the Cold War - which meant both men's achievements were hushed up and never officially recognised.

How can we cope with the tricky coronavirus now rampant worldwide? As the pandemic tightens its grip on the world, there are important unanswered questions about this novel virus: Why does this infection spread so rapidly from people with no symptoms? Why do some people become critical while others don't? Will a definitive treatment be found? The underlying key to these questions lie in our immune system. Immune cells are microscopic warriors, combating viruses and another pathogens.
Through the high-tech 'eyes' of next-generation microscopes and computer-generated imagery, we will see how our immune defense corps combat against microbes and what mechanism is expected to help develop treatment.

After 400 BC, a new philosophy was born in South east Asia, generated from the ideas of Buddha, a mysterious Prince from India who gained enlightenment while he sat under a large, shapely fig tree. He remains one of the most legendary and influential of all religious progenitors, but what of his actual life? In this biographical documentary, director David Grubin tells the historical tale of Gautama Buddha (563-483 BC), from his initial enlightenment through his death around the age of 80. In the process, Grubin makes an unusual point: that Gautama never once claimed to be God or God's emissary, but instead sought to find a way to bring peace and alleviation from suffering to others in a cruel and often insane world. In telling this story, Grubin combines a number of elements including original animations, testimony by contemporary Buddhists such as the 14th Dalai Lama Tenzin Gyatso, glimpses of sculptures and paintings that help tell Gautama's story, and much more.

Jessie Buckley narrates the extraordinary story of the first transatlantic communications cable. In 16 August 1858, a short message is telegraphed from County Kerry to Newfoundland, 3,000km away: ‘Europe and America are united by telegraph. Glory to God in the highest, on earth peace, good will towards men.’ The Morse code message is conducted along the new underwater transatlantic telegraph cable laid across the bed of the Atlantic Ocean. Sending the same message by ship would have taken at least ten days, but the transmission takes just hours and heralds the dawn of the modern communications age.
The quest is driven by visionaries and pioneers. Among them are Cyrus Field, a wealthy businessman who, despite his immense success, ends his life in poverty; Samuel Morse, inventor of the telegraph and Morse code; Isambard Kingdom Brunel, the British engineer who pushes boundaries and budgets; and Belfast physicist Lord Kelvin, who calculates how to achieve what had hitherto been deemed impossible. Together, their ingenuity and relentless pursuit helps realise one of the great scientific accomplishments of their age for which Valentia, on Ireland’s remote western coast, is ground zero.

A huge social experiment is underway. Fifty-five million Americans say they currently use cannabis, and that number is expected to grow as voters push for legalization in more and more states. The film investigates the story of cannabis from the criminalization that has disproportionately harmed communities of color to the latest medical understanding of the plant.
What risks does cannabis pose to the developing brain? How much do we know about its potential medical benefits? As cannabis becomes socially accepted, scientists are exploring its long-term health consequences.
