Just twenty years ago, the British Antarctic Survey (BAS) would not allow women to camp in Antarctica. In 2013, it appointed Jane Francis as its Director. Jane tells Jim Al-Khalili how an intimate understanding of petrified wood and fossilised leaves took her from Dorset’s Jurassic coast to this icy land mass. Camping on Antarctic ice is not for everyone but Jane is addicted, even if she does crave celery and occasionally wish that she could wash her hair. Fossils buried under the ice contain vi...

Until recently, it was thought that human brain development was all over by early childhood but research in the last decade has shown that the adolescent brain is still changing into early adulthood. Jim al-Khalili talks to pioneering cognitive neuroscientist professor Sarah-Jayne Blakemore who is responsible for much of the research which shows that our brains continue to develop through the teenage years. She discusses why teenagers take risks and are so susceptible to influence from their pee...

Matt Taylor talks to Jim Al-Khalili about being in charge of the Rosetta space mission to the distant comet, 67P. It is, he says, 'the sexiest thing alive', after his wife. He describes his joy when, after travelling for ten years and covering four billion miles, the robot, Philae landed on the speeding comet 67P; and turned the image tattooed on his thigh from wishful thinking into a triumph for science. Matt's father, a builder, encouraged him to do well at school. He wanted him to get a job i...

John O'Keefe tells Jim al-Khalili how winning the Nobel Prize was a bit of a double-edged sword, especially as he liked his life in the lab, before being made famous by the award. John won the prize for his once radical insight into how we know where we are. When he first described the idea of ‘place cells’ in the brain back in 1971, many scoffed. Today it is accepted scientific wisdom that our spatial ability depends on these highly specialised brain cells. A keen basketball player,John says, h...

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 these...

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 reci...

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 symp...

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’...

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…. Discovery looks at new ideas and technologies to enable companies to make more stuff at an affordable environmental cost. (P...

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.)

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. B...

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 trilo...

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 m...

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 ...

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 reassu...

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 bas...

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 d...

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 math...

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 author...

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 camera...

You have a headache and take a pill. The headache is gone, but what about the pill? What we flush away makes its way through sewers, treatment works, rivers and streams and finally back to your tap. Along the way most of the drugs we take are removed but the tiny amounts that remain are having effects. Feminised fish in our rivers, starlings feeding on Prozac-rich worms, and bacteria developing antibiotic resistance - scientists are just beginning to understand how the drugs we take are leaving ...

Patient power is on the rise. But is it rising too far? Frustrated by the time it takes to develop new drugs, the ethical barriers to obtaining clinical data or the indifference of the medical profession to obscure diseases, patients are setting up their own clinical trials and overturning the norms of clinical research. A DIY clinical trial sounds like a joke – and a dangerous one at that. But as Vivienne Parry discovers, it's real and on the rise as greater access to medical data allows more p...
