Just outside Paris, inside a hi-tech vault, and encased in three vacuum-sealed bell jars, rests a small metallic cylinder about the diameter of a golf ball. It may not look like much, but it is one of the most important objects on the planet. It affects nearly every aspect of our lives including the food we eat, the cars we drive, even the medicines we take. It is the Kilogramme, the base unit of mass in the International System of Units. Yet over time, its mass has mysteriously eroded by the weight of an eyelash. A change that, unbeknownst to most, unleashed a crisis with potentially dire consequences.
The film follows the ensuing high-stakes, two-year race to redefine the weight of the world, and tells the story of one of the most important objects on the planet.

The climate is changing faster than ever, which is why 'fix our climate' is one of the five goals of the Earthshot Prize. Prince William, Sir David Attenborough and Christiana Figueres highlight inspiring and often unexpected solutions to the challenge. In this film, we'll explain the scale of the problem posed by climate change and will introduce you to some amazing people already working on climate crisis. One of these three finalists will win the Earthshot Prize and get the platform and resources they need to scale their ground-breaking work. Nine more solutions for fixing our climate will receive the same support over the course of this decade.

The Coronavirus disease 2019 (COVID-19) has spread globally since 2019, resulting in a pandemic. While the majority of cases result in mild symptoms, some progress to pneumonia and multi-organ failure. The deaths per number of diagnosed cases is estimated at between 1% and 5% but varies by age and other health conditions.
In this special on the coronavirus, we're with health staff working on the front-line of the Covid-19 crisis - as well as the scientists, economists and virology experts who can answer the question... Coronavirus: Are We Doing Enough?

In just over 100 days, a new coronavirus has taken an unprepared world by storm, infiltrating every corner of the globe, sending entire nations into lockdown, killing thousands and infecting countless more. Across the world, governments are scrambling to react, hospitals are struggling to cope and an increasingly anxious public are starting to panic.
The world's media is awash with data, information and misinformation. But what are the facts? What is COVID-19 and why is this strain of coronavirus so dangerous? What happens in our bodies when the virus attacks? How does this compare to previous pandemics? What do all the the numbers really mean, and how can data modelling help us look for an exit strategy? This programme investigates the scientific facts and figures behind the biggest public health crisis in living memory, and explores the latest research from the frontline of the medical and scientific fightback.

Did China hide crucial information about Covid-19 from the world? What began with a handful of mystery pneumonia cases in Wuhan late last year has now left more than half a million dead worldwide. Beijing says it has been open and transparent throughout, but former BBC China Editor Carrie Gracie investigates how it delayed reporting the initial outbreak and evidence that Covid-19 could be spread by people. It also silenced doctors who tried to speak out.
The film also hears from one high-level insider who believes the animal market at the centre of the Wuhan outbreak should have been treated as a 'crime scene' and from experts who warn that this crisis may be a 'dress rehearsal' for an even more deadly pandemic in the future.

Over the last years, the world has experienced an energy revolution, driven by an urgent need to green the grid and save life on Earth as we know it. 50 years ago, a devastating oil crisis kicked off an energy revolution. The world set course to cut the costly habit of burning fossil fuels. With the urgent new threat of a changing climate, the drive to unleash the power of the sun, earth and wind has accelerated into a race for humanity's survival. Change is taken place but, is it happening fast enough to secure our future? Technologies are right here, right now, and they will enable the transition to 100% renewables, because winning the energy race means a win for the entire world.
