Televising the future: Nineteen Eighty-Four and the imagination of Nigel Kneale
Nineteen Eighty-Four is rightly regarded as a classic. George Orwell’s dystopia is shot through with powerful political imagery. ‘Big Brother’, ‘Room 101’, and the ‘Thought Police’ remain touchstones in contemporary debate. Adapted by Nigel Kneale and directed by Rudolph Cartier, starring Peter Cushing, Yvonne Mitchell, and André Morell, the BBC production caused outrage in the press, propelling Orwell’s novel to the front page. Televising the Future: Nineteen Eighty-Four and the imagination of Nigel Kneale examines the story behind the Kneale and Cartier adaptation, the relationship between the book and the teleplay, and the impact of the production.
Martin Rees: The world in 2050 on Earth and in space
A talk by Lord Martin Rees, the Astronomer Royal, about his new book ‘The End of Astronauts'. Human journeys into space fill us with wonder. But the thrill of space travel for astronauts comes at enormous expense and is fraught with peril. As our robot explorers grow more competent, governments and corporations must ask, does our desire to send astronauts to the Moon and Mars justify the cost and danger? Donald Goldsmith and Martin Rees believe that beyond low-Earth orbit, space exploration should proceed without humans. In The End of Astronauts, Goldsmith and Rees weigh the benefits and risks of human exploration across the solar system.

How will the additional care burden they face affect them in the workplace or has the pandemic revealed a greater urgency when it comes to action? Will we see more female leaders and a shrinking gender pay gap as a result or fewer?
Can precision medicines transform healthcare for chronic diseases
Precision medicines – targeting the right medicine to the right patient at the right time – have revolutionised the treatment of some cancers and rare genetic diseases, yet precision medicines for chronic diseases are far less common. Chronic diseases are biologically complex and driven by multiple mechanisms. To improve patient outcomes, we must move beyond the current standard of by unravelling the complex underlying biology, and pioneering and applying advanced technologies. Hear from a panel of experts about the potential for a precision medicine approach to transform care in chronic diseases.
