You may not have heard of scandium and yttrium, but rare earth elements like these are all around us – in our homes, at work and even in our pockets.
The problem is that they come almost exclusively from resource-hungry China, and if supplies start to dwindle our high-tech industries are at risk.
Horizon looks at the researchers who are trying to solve this, by making components that don’t need them, by developing ways to recycle them from electronic waste, and by investigating how to mine and process them here in Europe.
Political challenges rather than geological availability are what threatens the EU’s supply of raw materials, according to Dr Henrike Sievers from the German Federal Institute for Geosciences and Natural Resources, who is working on a project to map all of Europe’s own mineral resources.
Magnets are at the heart of our love affair with tech, but they are currently made from hard-to-get components whose supply is under threat. Now, European scientists are developing replacements based on cutting-edge manufacturing processes and common elements.
Rare earth deposits found in Sweden, Finland, Greece and Spain suggest that Europe could reduce its reliance on imports of these critical raw materials, but the biggest challenge facing scientists is how best to extract and process them.
Did you know there are 200 million insects for each human on the planet? This October, Horizon delves into the mysteries of this diverse set of creatures and their seemingly infinite survival skills. We talk to researchers about why it's vital to maintain the diverse range of insect species, find out how robots and ants can work together to solve problems and explore how the superpowers of bugs could be put to use for humans.
Heart disease kills almost two million people a year in the EU, so it is important to find different ways of keeping your heart healthy. This September, Horizon examines innovative ways of treating heart disease, including electric gene therapy to prevent heart attacks and a miniature heart implant. Plus, we look at how 4D imaging of mice and zebrafish can help regenerate human hearts.
Innovation should be taught as a subject in European schools, according to Tibor Navracsics, the EU’s Commissioner for Education, Culture, Youth and Sport, who says that education can be a defining factor in the life of young scientists.
Pan-European conference discusses the future of innovation in the EU.
Learning how the brain decodes subtle social signals like body language could help people with autism.
Food insecurity leads to increased migration, says Cristina Amaral.
