Why do women outlive men

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 live faster and die younger. So, is the gender gap here to stay?

Piltdown Man

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 horrible hoax. Jonathan Amos talks to palaeontologists and archaeologists about the case of Piltdown Man...

Particle Physics

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

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 thin...

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 smellin...

The Age We Made

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 roc...

The Age We Made - Part 3

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 lim...

The Age We Made - Part 2

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 ...

The Age We Made - Part 1

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 planeta...

End of Drug Discovery

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 wh...

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 ...

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 pe...

Frankenstein's Moon

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.

Episode 1

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 revelations transformed Antarctica from an unknown quantity on the map into a profoundly important continent i...

Artificial Photosynthesis

Chemist Andrea Sella explores the current race to do photosynthesis better than nature ever achieved. In just a few hundred years mankind has burnt fossil fuels that had taken natural photosynthesis billions of years to create. Now, around the world hundreds of millions of pounds are being spent on the race to develop a robust, cheap and efficient way to turn the light from the sun into fuels we can use. At a time when politicians everywhere debate the economic and climatic burdens of our future...

Artificial Blood

Could creating "blood" in the laboratory make infections passed on through blood transfusions a thing of the past? Vivienne Parry investigates. The drive behind the quest for creating a blood substitute was originally from the US Military - during the Vietnam War a clean, reliable and portable alternative to donor blood would have helped to save many lives. Donated blood can only be kept for a limited time, needs refrigerating and has to be cross matched according to which ABO group people belon...

Gene Therapy

Gene therapy - repairing malfunctioning cells by mending their DNA - offers an elegant solution to diseases, such as cystic fibrosis, caused by a single flawed gene. It's a very simple concept to describe - simply insert a 'normal' gene to do the job - but it's this process, the delivery of the gene, that's proving to be so difficult and time consuming. Since the first human study began in 1990 the field has struggled with various technical challenges and set-backs. But over a decade on, researc...

Flu

Two teams of virologists found themselves at the heart of bioterrorism maelstrom late last year when their studies on mutant bird flu were suppressed by US authorities. While security experts feared the reports were recipes for bioweapons of mass destruction, the researchers argued they held important lessons for the threat of natural flu pandemics developing in the wild. Now the authorities have backed down and the reports have been released. Kevin Fong hears how tiny variations in the genes of...
