Discovery

Andrea Sella is a science showman, whose theatrical demonstrations of chemistry are filling theatres up and down the country. He talks to Jim al-Khalili about his life scientific. Andrea is also Professor of Materials and Inorganic Chemistry at University College London and he and Jim discuss whether he would rather be known for his research into rare metals than for his whizz bang displays.

Baby girls born today in the UK can expect to live to 82 years old, whereas boys on average will die 4 years earlier. Evolutionary biologist Dr Yan Wong looks at the latest evidence suggesting that where ageing is concerned, men seem to be at a genetic disadvantage. From research on ancient Korean eunuchs to laboratory fruit flies, new studies seek the answer to why males across the animal kingdom...

The most notorious fraud in the history of Science is the focus of this week’s Discovery. Exactly one hundred years ago, British scientists announced their discovery of fossilised skull and jaw bones of what appeared to be the earliest human – a species of humanity closer to our prehistoric ape ancestors than any found before it. In 1912 it was a sensational find. In 1953 it was revealed as a horr...

Finding the Higgs boson on July 4th 2012 was the last piece in physicists' Standard model of matter. But Tracey Logan discovers there's much more for them to find out at the Large Hadron Collider. To start with there is a lot of work to establish what kind of Higgs boson it is. Tracey visits CERN and an experiment called LHCb which is trying to find out why there's a lot more matter than anti-matt...

Kevin Fong talks to one of the last two men on the Moon, 40 years after the final Apollo 17 mission blasted off on 7 December 1972. As an Apollo astronaut, Harrison Schmitt was special. He was was the only geologist ever to explore the lunar surface. The field work Dr Schmitt did, and the rocks he and his fellow astronauts brought back, revolutionised our understanding of the Moon and the Earth. D...

In this programme, Geoff Watts meets researchers attempting to unlock the mysteries of hallucination as well as some of those who experience the phenomenon. Geoff visits Dr Dominic Ffytche of the Institute of Psychiatry in London, and undergoes a stroboscopic experiment designed to induce hallucinations in subjects whilst their brains are being scanned. We hear some of the vivid accounts from hall...

Geoff Watts meets researchers attempting to unlock the mysteries of hallucination as well as some of those who experience the phenomenon. Hallucinations aren't what they used to be. Time was when reporting a divine vision would bring fame or fortune. The Enlightenment changed all that and nowadays you'd be more at risk of being handed a prescription for a major tranquilliser for reporting what you...

Gaia Vince concludes her journey through the geological age humans have launched. After climate change and mass extinction, she now explores moves how the world’s cities and manufactured artefacts (from mobile phones to plastic bottles) might become 'fossilised' and incorporated into the geological record. Some are bound to survive in crushed form for the rest of the Earth’s existence. Any distant...

Earth scientists say humanity’s impact on the Earth has been so profound that we have started a new geological time period on the planet. They call it, the Anthropocene. Gaia Vince explores our fundamental changes to the biosphere. The accelerating extinctions of animal and plant species: the rearing of agricultural animals in their billions: and, what some describe as, the general ‘macdonaldisati...

Humanity’s impact on the atmosphere with fossil fuel burning is so profound that we’re creating a new geological time period, say geologists. They’ve named it, the Anthropocene. In this part of her journey into the Anthropocene, Gaia Vince explores how fossil fuel burning will leave enduring marks in geological record forming on the Earth in current times. Climate change and ocean acidification ar...

Humanity’s impact on the Earth is so profound that we’re creating a new geological time period. Geologists have named the age we’re making the Anthropocene. The changes we’re making to the atmosphere, oceans, landscape and living things will leap out of the rocks forming today to Earth scientists of the far future, as clearly as the giant meteorite that ended the Age of the Dinosaurs does to today...

We are in desperate need of new medicines for the major diseases facing us in the 21st century such as Alzheimer's and obesity. And we are running out of antibiotics that are effective against bacteria that are now resistant to many old varieties. As bringing new and improved drugs to patients becomes more difficult and more expensive - it can take 20 years and around $1 billion to bring a medicin...

Nine million people in the UK alone have significant hearing problems. The mechanisms in our ears that help us hear are incredibly sensitive and are easily damanged by environmental hazards such as loud noises and chemicals or simply the passage of time. Despite the fact that many of us will gradually lose our ability to hear as we as a society grow older, many of us don’t actually know that much...

Is our taste in music, and how it's changed over the centuries, governed by creative genius or simply by survival of the fittest sounds, chosen by us the consumer? Does Darwin's theory of natural selection apply to more than just life on the planet? The idea of survival of the fittest and cultural evolution can be applied to many aspects of our lives; from fashion to the naming of our children. In...

What can astronomy tells us about great literature? Forensic astronomer Don Olson tells Andrew Luck-Baker about two of his investigative cases. He explains how plotting the path of the moon in 1816 solved a controversy about Mary Shelley's novel Frankenstein. The Texas State University professor also outlines his theory that a star referred to in Shakespeare’s Hamlet was inspired by a spectacular...

One hundred years ago, the first humans reached the South Pole of this planet. More than 40 years ago, man first walked on the moon. When will our species first set foot to explore the planet Mars? Kevin Fong seeks a likely launch date. He asks who will get us there and why we really need to explore the Red Planet. (Image: An image, released by NASA, of the terrain of Mars taken by the Curiosity r...

Jim Al-Khalili finds out about the life scientific of the British Antarctic Survey biologist Lloyd Peck. Amongst other creatures he studies giant sea spiders. They and other small animals grow far bigger than usual in the extreme cold. Diving is an important part of Lloyd's job and Jim hears what it's like to play football under the ice. Studies suggest that the sea temperature is rising, and Lloy...

One hundred years ago, Scott reached the South Pole. Fifty years later, the first geologist briefly walked on the moon. Kevin Fong asks if why we might want to return to the lunar surface and what will get us. He talks to that first lunar geologist of Apollo 17, Harrison Schmitt and Nasa's Chief Administrator Charles Bolden, among others.

Jim Al-Khalili meets Cambridge University neuroscientist Barbara Sahakian. She talks about her Life Scientific finding drugs to slow down the memory losses that happen in Alzheimer's disease. She worked in some of the first memory clinics that were set up in the US and the UK to help people who had problems remembering and has developed tests to find out if peoples' forgetfulness is the first sign...

Kevin Fong looks beyond the failure of Robert Falcon Scott's expedition to be the first to reach the South Pole and focuses instead on the scientific legacy of Scott's explorations of Antarctica between 1901 and 1912. In recent years, much has been written about Scott the polar loser and bungler. But that personalised focus ignores the pioneering scientific research and discoveries. The revelation...

Discovery this week goes in search of the Gangetic River Dolphin, an extraordinary creature which inhabits the muddy waters of the Ganges and Brahmaputra rivers. Not long ago, the dolphin was a common sight for people along these mighty water ways, but now it's one of the world's rarest freshwater mammals. Andrew Luck-Baker joins Indian biologists studying the dolphins and the threats to them alon...

After the most daring and complex landing of a robot on another planet, the search for evidence of life on Mars enters a new era. Nasa's Curiosity rover is now sitting inside Gale Crater, a vast depression close to the Martian equator. Also known as the Mars Science Laboratory, the one tonne machine is the most sophisticated science robot ever placed on another world. Over the coming years Curiosi...

Gareth Mitchell meets the engineers who are designing flying cars and green aircraft. Gareth has a go at flying a personal aircraft in the flight simulator at Liverpool University. Doctors Mike Jump and Mark White explain that the EU-funded project MyCopter is seriously looking at the prospect of flying personal vehicles that are as easy to drive as a car. Sophie Robinson, a Ph. D student at Liver...

Gareth Mitchell meets the engineers who will transform the way we fly around the world and finds out what aircraft might look like in the future. Gareth visits the flight gallery at the Science Museum in London with the curator, Dr Andrew Nahum, who shows him how the basic shape of aircraft has hardly changed in 70 years, since the days of the DC3. Andrew Nahum also talks about why Concorde was in...
