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-matter in the universe today. Dr Tara Shears of Liverpool University is her guide. Tracey also talks to

Last Man, First Scientist on the Moon

2012/12/03

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. Dr Schmitt also shares the human experience of running around another planet and explains why he

2012/11/26

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 hallucinators, including Doris, who has macular degeneration. Over the last year, her failing eyesight has

Hallucination 1/2

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 saw or heard. Hallucinating, in essence, the experience of seeing or hearing (and sometimes smelling or

The Age We Made

Discovery ·

2012/11/12

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-future geologist would recognise them as strange features unique in the planet’s 4 billion year rock

The Age We Made - Part 3

2012/11/05

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 ‘macdonaldisation’ of life on Earth. All three factors will leave striking evidence in the fossil record in the

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 are in the process of transforming the planet on such a scale that humanity has shifted Earth history

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’s researchers. In this four part series, journalist Gaia Vince looks at the impact of these

End of Drug Discovery

2012/10/15

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 medicine to market. In the second programme looking at the problem with drug discovery, Geoff Watts asks what

The sound of deafness

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 about the causes and consequences of deafness. What does the world sound like to a deaf person? How do

Darwin's Tunes

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 a world of digital sampling scientists have designed an experiment to see if they can create the

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 supernova which blazed in sky one year during the playwright’s childhood.(Image: Baron Frankenstein,

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 rover.

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 Lloyd investigates whether the animals he researches will be able to adapt and survive. And Lloyd talks

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 of dementia. More recently she has turned her attention to drugs that can improve the performance of

But that personalised focus ignores the pioneering scientific research and discoveries. The revelations transformed Antarctica from an unknown quantity on the map into a profoundly important continent in

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 along the stretch of the Brahmaputra in the state of Assam. In a joint project between Aaranyak, an

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 Curiosity will climb a mountain at the crater's heart, gathering evidence on one of science's greatest
