How to Find Love Online

Dr Xand Van Tulleken is single and looking for love. Mathematician Dr Hannah Fry wants to use him as her guinea pig to test whether the algorithms that dating sites use to match people actually work. While Hannah builds a dating site, Xand meets the scientists investigating online dating - and learns what pictures to use and what to write in his profile. He tries out a 'bot' that has automated a swiping app and has an MRI scan to find out whether his brain is equipped for love. 50 members of the public take part in some mini experiments at a date night - and Xand goes on various dates to test whether the algorithm is better than him choosing randomly.

Outcasts

In the last 30 years the world's urban areas have almost tripled in size, changing at a rate wildlife has never experienced before. As cities are built, animals are pushed out of their natural homes. Their stories are the most surprising and captivating of all. Today, these 'wild outcasts' find themselves fighting for their place in a land that once belonged to them. In this episode we feature elephants in Sri Lanka and see that competition between them and humans for land and resources is resulting in deadly territorial conflicts, which demand solutions. And on the Pacific coast of Costa Rica we meet a troop of capuchin monkeys and learn how our behaviour is affecting them, and raising big questions about their future. But we also discover where we learn to live with wildlife as neighbours, and give it the space and resources it needs, it can thrive. The resulting relationships between human and animals can be mutually beneficial. We meet an Amsterdam heron called Kiri who has been visiting the same house twice a day for the last 17 years, befriending its owner, and the Florida manatees whose population has recovered to such an extent under the guardianship of local human residents that, in recent years, they have been taken off the endangered species list, and contributed to a massive boom in the local tourism industry. We meet the swiftlets who have evolved to live only in people's houses and specially built swiftlet hotels in Indonesia. And the surprising story of a population of tiny foxes on a Californian island whose presence benefits the hardened military personnel of a US naval base. This hopeful but realistic episode culminates with the return of charismatic ocean giants to the world's most iconic city, as humpback whales breach against the New York skyline.

The Rom-Com

Mark begins with one of the most popular genres of all. They are sometimes sneered at by critics, but from the 1930s to the present day, many of our most beloved movies have been romantic comedies. From Bringing Up Baby and The Lady Eve by way of Annie Hall, When Harry Met Sally and Pretty Woman to Love, Actually (a particular Kermode favourite) - as well as recent hits such as The Big Sick and La La Land - Mark examines the cinematic tricks and techniques involved in creating a classic romcom. Mark celebrates old favourites, reveals hidden treasures and springs plenty of surprises. Examining films from Hollywood to Bollywood via other gems of world cinema, he reminds us how, much like love itself, the art of the romantic comedy is international.

The Allergy Fix

If you’ve been to a children’s birthday party lately, chances are at least one of the little guests had a portable needle loaded with epinephrine. Its standard equipment for a growing generation of highly allergic kids: more than three times as many children have food allergies now than twenty years ago. And one out of every three children is now allergic to foods, animals, or plants. Something puzzling, and frightening, is going on with our immune systems. The Allergy Fix travels across Canada and to the US, the UK and Germany to investigate why allergies are on the rise – and what’s being done about it.

The Science of Anti-Vaccination

Fewer children in the United States are getting vaccinated. That’s bad news for those kids, and also for public health in general.
