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.

The documentary tells the story of the extremely rare discovery of evidence of Roman crucifixion, unearthed in a routine archaeological dig in the Cambridgeshire Fens. When human remains were found alongside a variety of Roman artifacts, none of the team at Albion Archaeology saw anything out of the ordinary. But once the bones were washed back at HQ, something highly unusual was uncovered: a nail through the heel bone of one of the individuals. Could this be evidence of a Roman crucifixion? When they did some research, they found that only one confirmed example had ever been unearthed before, discovered in the 1960s in Jerusalem. To find out more, they called in renowned osteoarchaeologist Dr Corinne Duhig to investigate. With exclusive access to Corinne’s investigation and the remains themselves, The Cambridgeshire Crucifixion sets out to find out who this person was, how they lived and why they were put to death in this notoriously gruesome way. We perform a CT scan, DNA and isotope analysis of the remains, and use them to create a cutting-edge virtual autopsy of the skeleton, conducted by Corinne and one of her former students, biologist Prof Ben Garrod.
A supporting cast of expert contributors help to analyse the artefacts found at the Fenstanton site and reveal a compelling picture of life in Roman Britain in the 1st century CE. The film culminates in a world first: a full forensic facial reconstruction of a victim of Roman crucifixion, conducted by world-leading expert Joe Mullins.

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.

Follow actor William Shatner through interviews with the other actors who have portrayed starship Enterprise captains in five other incarnations of the Star Trek franchise. Shatner's subjects discuss their lives and careers before, during and after their tenure with Star Trek. With the use of conversations and archival footage, they explore the pressures, stigmas and sacrifices that accompanied their roles and their larger careers. During the process of the film and with help from the other Captains, Sir Patrick Stewart, Avery Brooks, Kate Mulgrew, Scott Bakula and Chris Pine, Shatner overcomes his disdain and learns to embrace his best known character, Captain James T. Kirk.

Dr Adam Rutherford tells the extraordinary story of the scientific quest to discover the secrets of the cell and of life itself. Every living thing is made of cells, microscopic building blocks of almost unimaginable power and complexity. The first part explores how centuries of scientific and religious dogma were overturned by the earliest discoveries of the existence of cells, and how scientists came to realize that there was, literally, more to life than meets the eye.

In the last episode, Iain discovers the remarkable impact of just one plant: grass. On the savannah of South Africa he sees how grass unleashed a firestorm to fight its greatest enemy, the forests. He shows how cutting your finger on a blade of grass shows us how it transformed life in the oceans. In Senegal, he meets the cleverest chimps in the world. And, in the ruins of the oldest temple on Earth, he tells the extraordinary story of how grass triggered human civilisation.
