It's been 15 years since the euro came into circulation and to mark the occasion Horizon is looking at what the future could have in store for finance. We talk to one economist who says the way to avoid another crisis is to keep banks small and boring, and we explore the effect of alternative local currencies on supporting small businesses. We also delve into some of the technology that could enable us to move to a cashless society, and we look at the growth of the so-called sharing economy, in which people share access to resources.
From eliminating checkout queues to potentially cutting counterfeiting and even terrorist financing, the rise of cash-free payment systems might not only change the way most of us pay but even pave the way to a cashless society.
People who use car-sharing services could soon be able to roam with different providers when travelling, much in the same way as people do with their mobile phone networks, thanks to a new piece of software which its inventor says will also help make car sharing economically viable in smaller cities and rural areas.
We need to return to a diverse, small-scale banking system in order to reduce the risk of another financial crisis, according to Professor Eckhard Hein from the Berlin School of Economics and Law, Germany, who was involved in the EU-funded FESSUD project examining the causes and consequences of the 2008 - 2009 financial and economic crisis.
This month, Horizon takes an in-depth look at a shared human trait – our emotions. We find out how science is seeking to better understand and regulate human emotions across a range of applications, from mental health to politics. We uncover the implications of a neuroscientist’s efforts to determine how the brain controls fear and anxiety, with possible implications for treating mental health disorders and autism. We explore how emotions shape our politics and ask whether this can help provide a different perspective on the Israeli-Palestinian conflict. And we look at research examining how apps and online games can help people manage their emotional sides.
Neon lights, astrophysics, lightning and, of course, televisions – plasma is all around us. But what exactly is it and how can we harness its power? This month, Horizon takes an in-depth look at the fourth state of matter, finding out how it could be used to fix environmental problems such as wastewater contamination and factory emissions. We speak to the scientists who are attempting to use plasma energy to create more powerful particle accelerators and probe the mysteries of the universe. We also find out how researchers are trying to recreate astrophysical plasma in their labs and investigate the potential of cold plasma to save lives.
Workshops focusing on intergroup emotions are showing how deeply-rooted beliefs can be changed to support conflict resolution.
The impact of heavy droughts, heatwaves and cold spells on energy demand and supplies would be lessened with seasonal climate forecasts that allow energy companies to better predict spikes in usage ahead of time, researchers say.
Psychological and physiological interventions are tackling intolerance for others.
Longer notice of extreme weather would help cap prices.
We need to adopt 100 solutions, says Project Drawdown vice president
