Showing results for "The Power Of Friendship" in Science & Engineering

Since 2006, Twitter has grown from 100 obsessive users to more than 500 million today - over 32 million of those in the UK alone. But how did such a radical transformation happen in just five years, and what does it mean for business, politics and the internet?

Science journalist Lydia Denworth takes us in search of the biological, psychological and evolutionary foundations of this important bond. She finds that the human capacity for friendship is as old as humanity itself, when tribes of people on the African savanna grew large enough for individuals to seek meaningful connection with those outside their immediate families. Lydia meets scientists at the frontiers of brain and genetics research and discovers that friendship is reflected in our brain waves, our genomes and our cardiovascular and immune systems.
