Future Flight: Prog 2 of 2

Discovery ·

2012/07/30

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 Liverpool University, explains how her research into the safety and stability of auto-gyros, flying machines

2012/07/23

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 service for such a short time. David Caughey, Emeritus Professor of Aeronautical Engineering at

Artificial Photosynthesis

2012/07/16

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 belong to

Gene Therapy

Discovery ·

2012/07/02

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, researchers

Legacy Of Alan Turing - Episode Two

Discovery ·

2012/06/25

Alan Turing, born 23 June 1912, is famous for his key role in breaking German codes in World War II. But for mathematicians, his greatest work was on the invention of the computer. Alan Turing's brilliance at maths was spectacular. Aged 22, just a year after his graduation, he was elected a fellow of King's College Cambridge. And it was just a year after that, that he turned his attention to problems in the foundations of mathematics and ended up showing that a simple machine, set up to read and

Flu

2012/06/11

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 bird

Transit of Venus 2012

2012/06/05

Astronomer Marek Kukula from the Royal Observatory at Greenwich explores the scientific implications of the forthcoming transit of Venus across the face of the Sun, a rare astronomical event that will not occur again until 2117. Previous transits have helped establish fundamental facts about our solar system, including the distance and relative positions of all the planets that orbit our sun. But now, the forthcoming transit in June 2012, the last this century, will help planet hunters searching for

Professor Jim al-Khalili talks to Cern physicist Tejinder Virdee, about the search for the elusive Higgs boson, also known as the "God particle". Last December, scientists working at the Large Hadron Collider caught a tantalising glimpse of the Higgs; but they need more data to be sure of its existence. Twenty years ago, Tejinder set about building a detector within the Large Hadron Collider that's capable of taking 40 million phenomenally detailed images every second. Finding the Higgs will

Hurricane Rash

2012/05/21

Plastic Surgery does not always have a good press, more often associated with the excesses of Hollywood. But the birth of modern day reconstruction has far nobler roots. Dr Kevin Fong looks at the surprising, and heroic origins of the field of plastic and reconstructive surgery. It is a field that was born in response to the great air-battles of World War II, and the development of a new fighter plane - the Hawker Hurricane - that left its legacy not just in terms of success in the air, but in

The Science of Morality

2012/05/14

How fixed are our moral beliefs? Can these beliefs be reduced to neurochemistry?While we may believe that our moral principles are rigid and based on rational motives, psychological and neuroscientific research is starting to demonstrate that this might not actually be the case.In this edition of Discovery, Dr Carinne Piekema investigates how scientific studies are starting to shed light on how our social behaviour is affected by our environment and neurochemistry. She discusses with Carol Dweck

1000 Days: A Legacy of Life

2012/05/07

Imagine if your health as an adult is partly determined by the nutrition and environment you were exposed to during a critical period of development - the first 1000 days of life. A strong body of scientific evidence supports this explosive idea, and is gradually turning medical thinking on its head. To understand the cause of chronic adult disease, including ageing, heart disease, diabetes, osteoporosis, obesity and lung problems we need to look much further back than adult lifestyle – but to the

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?

Can the heroic age of Antarctic exploration help to show us the way back to the Moon?One hundred years ago, Scott reached the South Pole. However, more than four decades passed before people went back there. On the Moon, Neil Armstrong took his leap for mankind in 1969 and it has been forty years since the last astronaut left the lunar surface. Presenter Kevin Fong talks to space scientists and historians to find out if Robert Scott's Antarctic exploits provide a road map for future human

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 in
