Does Money Make you Mean?

Discovery ·

2015/03/23

Can money really make a person mean? In this second and final programme, Jack heads to Hong Kong to explore whether our preoccupation with money is affecting the way we treat other people. Jack hears about the growing body of evidence indicating that we behave with less empathy, kindness and generosity when exposed to the idea of money. Most of the research so far is from the United States, but Jack stages his own psychology experiment at the City University of Hong Kong to explore how far

Does Money Make you Mean?

Jack Stewart heads to Los Angeles, home to many of America's rich and famous, to explore what impact wealth has on our moral behaviour. Hollywood often has plenty to say about the corrupting influence of money, but can science tell us even more.Professor Paul Piff of the University of California explains his research, which finds that the richer a person becomes the more selfish, narcissistic and less generous they tend to be. However, not everyone is convinced that the American dream is a recipe

Finding Your Voice

Comedy performer and broadcaster Helen Keen, explores a rare condition that she herself once suffered from - selective mutism or SM. It is an anxiety disorder that develops in childhood. Those affected by SM can usually speak fluently in some situations, notably a home, but remain silent elsewhere - such as in school, with extended family members, or even parents. Their inability to speak is so severe that it has been likened to a phobia of speaking, and is often accompanied by the physical

Placebo Problem

Discovery ·

2015/03/02

In recent years the term 'placebo effect' - the beneficial effects on health of positive expectations about a drug or some other treatment - has become familiar. It has also been shown to be a powerful aid to medicine. The nocebo effect is simply its opposite - it’s ugly sister. One difference is that its breadth and magnitude have been much less studied. Another is that it may be even more powerful than the placebo effect. It is easier to do harm than good. And this is worrisome because nocebo’s

How can manufacturers of the world supply the growing demand for consumer products without breaking the planet’s bank of natural resources? By the middle of the century, there will be 2 billion more people in the world. Based on current trends, there’ll be many more consumers with the money to buy cars, washing machines, mobile phones, fashion – the shopping list goes on….

2015/02/16

Hundreds of millions of computers, mobile phones and televisions are thrown away every year around the world. In this week’s Discovery Gaia Vince will be looking at the reasons behind this rapidly growing mountain of electronic waste and asking, who is responsible? The manufacturers or the consumers? When our gadgets break, maybe we should just be repairing them. And Gaia attends a party where people are fixing stuff for themselves.(Photo: Discarded laptops.)

The Science of Smell

Discovery ·

2015/02/09

Pamela Rutherford explores our neglected sense of smell. How is the brain able to detect and tell apart the countless number of smells it comes across and what happens when the system goes wrong? She finds out how people can lose their sense of smell and why it’s the very strong associations between smell and memory that allow your sense of smell to come back. Not only can people lose their sense of smell and become ‘anosmic’ but in rare cases they can hallucinate smells, so called phantosmia. But

The Life Scientific: Richard Fortey

Richard Fortey found his first trilobite fossil when he was 14 years old and he spent the rest of his career discovering hundreds more, previously unknown to science. He is a Professor of Palaeontology at the Natural History Museum and talks to Jim al-Khalili about why these arthropods, joint-legged creatures which look a bit like woodlice and roamed the ancient oceans for almost 300 million years, are so important for helping us to understand the evolution of life on our planet.These new trilobite

2015/01/26

Maggie Boden is a world authority in the field of artificial intelligence – she even has a robot named in her honour. As research professor of Cognitive Science at the University of Sussex, Maggie has spent a lifetime attempting to answer philosophical questions about the nature of the human mind, but from a computational viewpoint. “Tin cans”, as she sometimes calls computers, are information processing systems, the perfect vehicle, she believes, to help us understand, explore and analyse the mind

Hot Gossip - Part Two

Discovery ·

2015/01/19

In the second of two programmes, Geoff Watts continues to explore the science, history and cultural implications of gossip. Gossip has a bad reputation and for the most part, and deservedly so. Yet, on-going research appears to suggest that gossip does serve a useful purpose. Not least because our brains may be hard wired for it. Researchers in Boston have used a technique known as binocular rivalry (showing different images to left and right eye at the same time) to suggest that gossip acts as an

Hot Gossip - Part One

Discovery ·

2015/01/12

If language elevates us above other animals, why does human society seem to spend so much time gossiping? Perhaps it's because without gossip there would be no society and language would be much less interesting. In the first of two programmes, Geoff Watts explores our fascination with small talk and chit chat. Where did gossip come from, why did it evolve and how has it changed (and changed us) in the digital age?If your guilty pleasure is rifling through gossip magazines, then here's a reassuring

Virtual Therapy

2015/01/05

E-Therapy has come a long way since the (slightly tongue in cheek) days of Eliza, a very early attempt at computer based psychotherapy. Eliza was little more than an algorithm that spotted patterns in words and returned empty, yet meaningful-sounding questions back at the user. All sorts of e-therapies are now available to help low-moderate level mental health issues. But could Virtual Reality technology bring the next great leap in our understanding of mental processes, and, in turn, be the basis

Professor Adam Hart explores the newest area in the science of animal behaviour – the study of personality within species as diverse as chimpanzees, song birds, sharks and sea anenomes. What can this fresh field of zoology tells us about the variety of personality among humans? We are all familiar with the variety of temperament and character in the dog, Canis lupus familiaris, but this is the product of selective breeding by humans over generations. A more surprising revelation is that up and down

Can Maths Combat Terrorism?

2014/12/22

Dr Hannah Fry investigates the hidden patterns behind terrorism and asks whether mathematics could be used to predict the next 9/11. When computer scientists decided to study the severity and frequency of 30,000 terrorist attacks worldwide, they found an distinctive pattern hiding in the data. Even though the events spanned 5,000 cities in 187 countries over 40 years, every single attack fitted neatly onto a curve, described by an equation known as a 'power law'. Now this pattern is helping

New Space to Fly

2014/12/15

As our skies become more crowded Jack Stewart examines the long awaited modernisation of air traffic control. With traffic predicted to reach 17 million by 2030 more flights will mean more delays. For many a new approach to controlling flights is long overdue since aircraft still follow old and often indirect routes around the globe, communication between the ground and air is still by VHF radio, and any flexibility is heavily constrained by a fragmented airspace operated by many national

Many people are living with chronic diseases such as rheumatoid arthritis and inflammatory bowel conditions in which the body attacks itself. Although drug treatments have improved over recent years they do not work for everyone and can have serious side effects. Now researchers such as neurologist Dr Kevin Tracey of the Feinstein Institute for Medical Research, and rheumatologist professor Paul-Peter Tak of Amsterdam University, are trying a new approach to improving the lives of these patients

Jim al-Khalili talks to professor Elspeth Garman about a technique that has led to 28 Nobel Prizes in the last century.X- ray crystallography, now celebrating its 100th anniversary, is used to study the internal structure of matter. It may sound rather arcane but it is the reason we now know the structure of hugely important molecules, like penicillin, insulin and DNA. But while other scientists scoop up prizes for cracking chemical structures, Elspeth works away behind the scenes, (more cameraman

It is the nearest and most dominant object in our night sky, and has inspired artists, astronauts and astronomers. But fundamental questions remain about our only natural satellite. Where does the Moon come from? Although humans first walked on the Moon over four decades ago, we still know surprisingly little about the lunar body's origin. Samples returned by the Apollo missions have somewhat confounded scientists' ideas about how the Moon was formed. Its presence is thought to be due to another
