What does happiness mean to you? Friends, family, the rush of a crowd or the joy of solitude? Happiness is a fundamental human desire, yet we often struggle to achieve it. Understanding what does and does not make us happy is a growing field of scientific study. In this edition of The Why Factor, Sandra Kanthal asks if we can really teach people how to be happy.Laurie Santos – Professor of Psychology, Yale University Bruce Hood – Professor of Developmental Psychology, University of Bristol Ellie Wright – Student, University of Bristol Meike Wiking – CEO, Happiness Research Institute Jan-Emmanuel de Neve – Associate Editor, World Happiness Report Professor Dixon Chibanda – Psychiatrist and Founder of The Friendship Bench Project(Photo: Notepad and smile emoticon on books.

Blending ingredients to produce something new is a distinctively human urge, and one of our most creative acts. We blend all sorts of products, such as tea, champagne and perfume. Did you know that blended whiskies combine over 30 single malts? In this week’s Why Factor, Barry Smith asks - why we blend. And why some blends work whilst others don’t.Presenter: Barry Smith Producer: David Edmonds Editor: Richard Knight

As the world grows more urban, humanity moves further away from nature. Could this be the reason anxiety has become the most diagnosed mental illness in the west? The idea of mindfulness is becoming more popular as the mainstream grows more aware of how panicked we all are. How are we tackling this issue? Jordan Dunbar dives into a niche of researchers and therapists who are learning about and treating the negative symptoms of urban life with a dose of nature.Lea Kendall, Therapist and James Kendall, Wilderness Instructor Birgitta Gatersleben, Environmental Psychologist Patricia Hasbach, Clinical Psychotherapist Harini Negrenda, Professor of Sustainability at Azim Premji University, Bangalore, India Layla McCay, Centre for Urban Design and Mental Health Presented and Produced by Jordan Dunbar Researcher Julia Webster Editor Richard Knight

The sports teams we support say something about who we are. Our identities are bound up with the men and women who play for our side – and we experience their success and failure as if they were our own. But, if supporting your team is so important, how can there be so many people who think these contests are of little consequence? Sandra Kanthal explores why we care so deeply about the outcome of a game.Michael Sandel, professor of Government Theory - Harvard University Dr Martha Newson, cognitive anthropologist - Oxford University Dr Alan Pringle, faculty of Medicine and Health Sciences - University of Nottingham Stephen Reicher, professor of Social Psychology -University of St Andrews Matthew Engel, sportswriter and author of That’s the Way It Crumbles Nisha Nair, assistant professor of Business Administration – University of Pittsburgh(Photo: Pakistan cricket superfans.

If the idea of being all alone, in silence, for long periods of time fills you with dread, it might be hard to understand why anyone would choose to be a hermit.

This week, Shabnam Grewal asks: why do people become hermits?Guests: Sara Maitland - writer, feminist and Catholic hermit. Ansuman Biswas - artist and part-time hermit Michael Finkel - writer of The Stranger in the Woods, about American hermit Christopher Knight Meng Hu - former librarian who runs a website called Hermitary Prof Takahiro Kato - psychiatrist who specialises in hikikomori Music by Ansuman Biswas and Stanley Keach.Image: An isolated log cabin (Credit: Getty Images)

Open plan offices, hot-desking, group brainstorming sessions: collaboration seems to be king in the modern workplace. Recent studies have found that we are spending up to 80% of our working days either in meetings or dealing with requests from our colleagues. But is working together really the best way? Is the idea of collaboration something we’re fetishising at the cost of productivity and creativity, and have we lost sight of the benefits of working alone? Nastaran Tavakoli-Far shares her own dislike of the BBC’s open-plan office and asks, in some desperation: why should we work together?Guests:Art Markman, professor of psychology and marketing at the University of Texas at Austin, and author of Bring Your Brain to Work Kerstin Sailer, reader in social and spatial networks, The Bartlett School of Architecture, University College London Susan Cain, author of Quiet: The Power of Introverts in a World That Can't Stop Talking John Maeda, global head of design at Automattic Image: Workers in an open-plan office (Credit: Getty Images)

Schadenfreude is a German word that means “harm-joy”. It is the pleasure we feel from someone else’s misfortune, and it can come in many shades. It is the laughter we can’t stifle when someone unexpectedly falls over, or the triumphant pleasure we feel when a rival is defeated. We can also feel it when something bad happens to someone we genuinely like. Edwina Pitman examines why, even when we’re happy and successful, we can’t help but enjoy others’ bad luck.Contributors: Esther Walker - journalist Dr Tiffany Watt Smith - cultural historian and author of Schadenfreude: The Joy of Another’s Misfortune Professor Richard Smith - professor of psychology, University of Kentucky Dr Andre Szameitat - reader in psychology, Brunel University Anuvab Pal - Comedian Mike Wendling - Editor, BBC TrendingPresented and produced by Edwina Pitman Editor: Richard Knight(Photo: Cheerful young woman lying on sofa with laptop in modern office lounge.

The history of computing is filled with the accomplishments of women. But in the West, the number of women taking computer science degrees has fallen sharply from its peak in the 1980s.In the developing world, however, the trend is going in the other direction, because learning to code offers economic opportunities not available to women before. Women are still outnumbered in computer science classrooms, but there are more of them.In this edition of The Why Factor on the BBC World Service, Sandra Kanthal asks why there areso few women in computer science, and what is driving them from a field they helped to create?Guests: Dame Wendy Hall, Regius Professor of Computer Science, University of Southampton Dr Barbara Ericson, Assistant Professor of Information, University of Michigan Dr Anjali Das, Head of Learning, Centre for Computing History Miriam Posner, Assistant Professor of Information Studies and Digital Humanities, UCLA Noemi Titarenco, Software leader and product manager, Los Angeles Fereshteh Forough, Founder: Code To Inspire Apple Macintosh Commercial – 1984 produced by Fairbanks FilmsImage: A woman studies a computer screen (Credit: Getty Images)

Most of us feel some need to know a roadmap of our past, our connections with a family tree which took root before we were born. We look for stories to tell about where we come from and seek answers in the lives of our ancestors, even in the DNA they pass on to us. In this edition of the Why Factor, Viv Jones asks why we have such a fundamental need to discover the stories of our heritage, and what they tell us about ourselves.
