They call them 'The Unexpected Survivors'. The casualties from the war in Afghanistan whose injuries were so severe that they were not expected to survive, but who survived nevertheless. In October, after 13 years Britain and the United States officially brought their combat operations in Helmand Afghanistan to an end. Camp Bastion, the coalition stronghold – once one of the largest military bases in the world – has been dismantled leaving a handful of buildings that will now be handed over to t...

Professor Brian Cox of Manchester University describes how he gave up appearing on Top of the Pops to study quarks, quasars and quantum mechanics. Although he describes himself as a simple-minded Northern bloke, he has acquired an almost God-like status on our TV screens, while the ‘Cox effect’ is thought to explain the significant boost to university admissions to read physics. He talks to Jim al-Khalili about learning to be famous, his passion for physics and how he sometimes has difficulty cr...

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...

Rebecca Morelle talks to explorers of deep ocean trenches, from film-maker James Cameron to biologists discovering dark realms of weird pink gelatinous fish and gigantic crustaceans. The deepest regions of the ocean lie between 6,000 and 11,000 metres. Oceanographers term this the Hadal Zone. It exists where the floor of abyss plunges into long trough-like features, known as ocean trenches. The Hadal zone is the final frontier of exploration and ecological science on the planet. At its most extr...

Accidents happen in science labs all over the world, but when you’re working with deadly pathogens the consequences can be disastrous. The reputation of America’s ‘gold standard’ The Centres for Disease Control and Prevention in Georgia has recently become tarnished as news emerged that 80 workers were inadvertently exposed to live anthrax, and a deadly strain of flu was accidentally sent to another lab. Further reports of tick-box safety culture, lethal samples sent in ziplock plastic bags and ...

Infectious bacteria are becoming resistant to the drugs that used to kill them. The last new class of antibiotics was discovered in the 1980s. There is little in the development pipelines of the world’s pharmaceutical industry. Drug companies got out of antibiotics as their attention switched to much more lucrative daily medicines for chronic diseases. Public funding on antibiotic research has also withered. Now that the gathering crisis of antibiotic resistance is becoming recognised by politic...

The discovery and harnessing of antibiotic drugs in the mid-20th Century led some medics to predict the end of infectious diseases. But the bacteria fought and continue to fight back, evolving resistance to many of the drugs that used to kill them. Public health officials warn that without new drugs, medicine will return to the days where ‘a cut finger on Monday leads to death of Friday’. Without protective antibiotics to keep infections at bay, scores of standard surgical operations and chemoth...

On 6th August, the space probe Rosetta ends its 10 year journey and arrives at Comet 67P/Churyumov-Gerasimenko. If all goes well, Rosetta will be the first spacecraft to go into orbit around a comet. The European Space Agency probe will then accompany the comet until December 2015, studying the 4 kilometre-wide lump of ice and rock dust at a level of detail far surpassing any previous comet flyby. In the words of Rosetta scientist Joel Parker, “Previous comet missions have been one-night stands,...

Professor Sir Michael Rutter has been described as the most illustrious and influential psychiatric scientist of his generation. His international reputation has been achieved despite the fact that as a young doctor, he had no intention of becoming a researcher, nor interest in becoming a child psychiatrist. In fact he became a world leader as both. His career has spanned more than five decades and is marked by a remarkable body of high-impact research and landmark studies. The theme running thr...

At the start of 2014 meteorologists warned of a possible El Nino event this year. The portents were persuasive – a warming of the central Pacific much like that which preceded the powerful El Nino event of 1997. But since then the Pacific climate system seems to have stalled. What’s going on? What are the prospects for an El Nino to develop later this year? What impacts might it have? Roland Pease delves below the Pacific surface to find out what drives El Nino cycles, the most powerful single c...

Adam Hart looks at how new developments in understanding insect behaviour, plant cell growth and sub cellular organisation are influencing research into developing robot swarms. Biological systems have evolved elegant ways for large numbers of autonomous agents to govern themselves. Staggering colonies built by ants and termites emerge from a decentralized, self-governing system: swarm intelligence. Now, taking inspiration from termites, marine animals and even plants, European researchers are d...

General anaesthetics which act to cause reversible loss of consciousness have been used clinically for over 150 years. Yet scientists are only now really understanding how these drugs act on the brain and the body to stop us feeling pain. Linda Geddes reports on the latest research using molecular techniques and brain scanners. Linda visits the Anaesthesia Heritage Centre where William Harrop-Griffiths, president of the Association of Anaesthetists of Great Britain and Ireland, tells her about t...

Geoff Watts investigates the latest thinking about our brain power in old age. He meets researchers who argue that society has overly negative views of the mental abilities of the elderly - a dismal and fatalistic outlook which is not backed up by recent discoveries and theories. Geoff talks to professor Lorraine Tyler who leads a large study in Cambridge (CamCAN) which is comparing cognition and brain structure and function in 700 people aged between 18 and 88 years old. He also meets scientist...

Most traffic accidents are caused by human error. Engineers are designing vehicles with built in sensors that send messages to other cars, trucks, bikes and even pedestrians, to prevent collisions happening. The idea is to make the vehicles react to whatever's going on faster than the human drivers. Jack Stewart drives around the university town of Ann Arbor, in Michigan, in some of the many vehicles that are fitted with experimental devices in the world's largest connected vehicles project. He ...

ITER is the most complex experiment ever attempted on this planet. Its aim, to demonstrate that nuclear fusion, the power of the Sun, can give us pollution free energy that we can use for millions of years. But at the moment, it's still largely a vast building site in the Haut Provence of southern France, with little prospect of any nuclear reactions there for another decade. A recent management report made damning criticisms of the way ITER is run, of the relations between the central organisat...

Dr Tiffany Jenkins asks what our brains can tell us about art. Can there ever be a recipe for beauty? Or are the great works beyond the powers of neuroscience? She talks to Professor Semir Zeki of University College London, the first person to coin the term, neuroaesthetics, about what happens in the brain when people in a scanner see paintings or hear music. Professor Gabi Starr at New York University tells Tiffany Jenkins why she thinks there are parts of the brain that light up when we like a...

Mark Miodownik's chronic interest in materials began in rather unhappy circumstances. He was stabbed in the back, with a razor, on his way to school. When he saw the tiny piece of steel that had caused him so much harm, he became obsessed with how it could it be so sharp and so strong. And he's been materials-mad ever since. Working at a nuclear weapons laboratory in the US, he enjoyed huge budgets and the freedom to make the most amazing materials. But he gave that up to work with artists and d...

Whatever happened to biofuels? They were seen as the replacement for fossil fuels until it was realised they were being grown on land that should have been used for food crops. But now there is serious research into new ways of producing biofuels, from waste materials, from algae and from bacteria. Gaia Vince takes to the water of Strangford Lough in Northern Ireland where Professor Matthew Dring and Dr Karen Mooney from Queens University, Belfast, are experimenting in growing algae that could b...

Biofuels were hailed as the environmental solution to fossil fuels not that long ago. Made from living crops they take up carbon dioxide as they grow. So burning them shouldn’t disturb the balance of warming gases in the atmosphere. But for the last few years the publicity about biofuels has been mainly negative. And for good reason – biofuels are made from crops such as oil palm - grown in place of food crops or even rainforests. In some cases using these crops actually produces more CO2 than b...

An extended interview with the Nobel prize laureate. Peter Higgs tells Jim Al-Khalili that he failed to realise the full significance of the Higgs boson and to link it to the much celebrated Standard Model of Physics. He puts the oversight down to a string of missed opportunities, including one night at a physics summer camp when he chose to go to bed early. Working alone in Edinburgh in the 1960s, Peter Higgs says he was considered "a bit of a crank... No-one wanted to work with me". In 1964, h...
