Quantifying the impact of humanity on the earth's natural systems. Why human activity now has a larger effect on our planet than the forces of nature. We look at how mathematical equations can now be used to compare historical natural processes with contemporary man made changes. And we ask where current developments will take us in years to come.The Queen Elizabeth Prize for Engineering has been awarded to the inventors of digital imaging sensors. First invented in the 1970's, many of us use this technology everyday. These sensor can be found inside every digital camera ever made, from the devices used on space probes to collect distant images from the far reaches of the universe to the ubiquitous pocket cameras in our mobile phones.The earth is surrounded by junk - space junk. Many thousand of pieces of junk orbit the planet, left over from the history of everything we've ever sent into space. A new project has given a voice to this junk, and created a machine which plays simulated sounds of the junk as it passes overhead.Producer: Julian SiddlePresenter: Gareth Mitchell

Folge vom 02.02.2017Wildlife trafficking, New quantum computers, Ancient bird beaks, Glassblowing.Conservation and conflict. A year long BBC investigation has exposed an illegal animal trafficking network stretching from West Africa to the Middle East and Asia. Traffickers have used fake permits to undermine international conservation efforts.New developments in Quantum computing. Sussex University are building a new type of modular Quantum computer. We attempt to explain what Quantum computing is.A Massive citizen science project to map bird beak evolution- using records from the Natural History Museum.And the last scientific Glassblower at Imperial College gives us a demonstration of his craft.

Folge vom 26.01.2017Crime, volcanoes, ghosts and how we are influenced by the genes of unrelated othersThe genes of unrelated others can influence our health and behaviour. New research suggests the genetic make up of our partners can have a profound influence on our lives. Scientists have quantified genetic influence , in mice at present but the plan is to try to extend this to human interactions. If accepted this has potentially far reaching consequences for studying heritability and also perhaps modern medicine as the findings suggest an illness can in part be influenced by those we live with. The use of DNA evidence in criminal cases has sometimes been given far more weight than it deserves. In the worst examples there have been miscarriages of justice where DNA evidence has been misinterpreted. The fiction of DNA as a 'magic bullet' pervades TV drama and films - but views of DNA evidence as infallible are also widely held amongst the public, police and lawyers. Forensic specialists explain what we can and can't find from DNA evidence.Oxford's Bodleian library has manuscripts stretching back to medieval times depicting volcanos discovered in the 6th century. These manuscripts also contain remarkable interpretations of eruptions and associated volcanic events, often mixed with mythology. Although those recording such events did not understand what they were scientifically, some of the depictions and ideas of what was happening are surprisingly accurate. Roland Pease and Professor David Pyle take a look at this remarkable collection.Nearly a hundred years ago, Oliver Lodge, eminent physicist and the first to demonstrate radio waves, published a book about life after death. It was entitled 'Raymond' after his son who was killed in the First World War. Lodge was a believer in ghosts and telepathy, and conducted experiments to test their existence. Adam Rutherford and Samira Ahmed look at how Oliver Lodge squared his scientific and spiritualist beliefs - and how the latter led to him, as Britain's most well know scientist of his time, being written out of scientific history.

Folge vom 19.01.2017Antarctic science rescue, Killing cancer with viruses, Measuring wind from space and the Last man on the moonWhy the British Antarctic science base is being temporarily abandoned. New cracks have appeared in the Ice shelf on which the Halley research station sits.The promise of viro-therapy for treating cancer. Scientists have successfully used a virus to kill cancer cells. They say this could form the basis for a vaccine that could be injected to destroy tumours.The limitations of mouse models. Many animals are used for testing treatments intended for humans, we explain why the results of such experiments can't always be applied to people.Measuring wind speeds from space. A new satellite will lead to more accurate weather forecasts. Gene Cernan, the last man on the moon. We celebrate the charismatic astronaut who has died aged 82.
