Horizon looks at the big implications of the science of the very small, from the promise of microscopic machines that kill damaged cells, to the search for ways to make sure that nanomaterials are safe.
Nanotechnology involves examining and developing structures so tiny that they are only a fraction of the width of a human hair. When materials get this minuscule, their properties change dramatically – in new and sometimes unexpected ways.
Horizon looks at how nanorobots could carry drugs into the body without affecting healthy cells, and sees how these tiny particles and structures are already in products we use every day – like cosmetics, sun cream, and even parts of your TV.
We also hear from Professor Kai Savolainen, director of the Nanosafety Research Centre at the Finnish Institute of Occupational Health in Helsinki, who talks about research into the risks of nanomaterials, and, also, their benefits to society.
Professor Kai Savolainen, director of the Nanosafety Research Centre at the Finnish Institute of Occupational Health in Helsinki, coordinates the NanoSafety Cluster. He believes more needs to be done to understand the risks of nanotechnology.
To mark the European year of cultural heritage, Horizon explores how science is helping to uncover more about our past and to preserve our art, landscapes, buildings and ways of life for the future. We discover why prehistoric humans chose to paint rock art where they did, and how farming techniques from hundreds of years ago could help fight climate change today. Plus, we learn how cultural heritage feeds into European identities and what can be done to prevent the destruction of historical sites during wartime.
The way we work is undergoing a major shift thanks to technological development and demographic change and, this month, Horizon looks at how research is helping us stay ahead of the game. We find out how decisions made early in your career could determine when you retire, and how to get the most out of the relationship between humans and machines in factories. We also investigate some of the ethical issues that could arise in the jobs of the future and how best to take them into account.
Swarms of firefighting drones could one day be deployed to tackle hugely destructive megafires that are becoming increasingly frequent in the Mediterranean region because of climate change, arson and poor landscape management.
The challenge of how to rebuild society following conflict is a difficult question that arises all too frequently, but recent studies have demonstrated that putting people at the centre of the process and enabling cooperation on politically neutral issues can help build peace.
Large fires are increasingly common in the Mediterranean region.
Where does one start to fix a broken society?
Destruction of cultural heritage sites can be a war crime as they form part of people's emotional landscape, according to Dr Margarete van Ess.
