Scientists around the world are asking themselves the same questions. Over the decades the focus on dolphin research has changed from asking 'how intelligent are dolphins?' to 'how are dolphins intelligent?' and we look at research from the world's foremost dolphin experts for the answers.

Of the four elements, air is the most elusive because we can't see it. There's something very magical about it. One of the ways we transform food is by getting air into it. Think of the soufflé, think of the loaf of bread. These things are elevated by the fact that they now contain air. They're ethereal. Visit food labs and Moroccan fields as Michael Pollan delves into the science of bread-making and the nature of gluten.

All cooking is transformation, and in that sense, it's miraculous, it's alchemy. But of all the different transformations we call cooking, fermentation is the most miraculous and the most mysterious. And that's because it doesn't involve any applied heat at all. Discover how microbes help turn raw ingredients into delicacies like chocolate and cheese as Pollan tackles the mysterious process of fermentation.

As he tries his hand at baking, brewing and braising, acclaimed food writer Michael Pollan explores how cooking transforms food and shapes our world. In the first espisode, with help from Aboriginal hunters and a barbecue pit master, Pollan shows how fire shaped human gastronomy, and weighs our duty to the animals we eat.

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.
