In August, Horizon takes a look at the quest to make Europe’s cities environmentally sustainable, while also ensuring a healthy and prosperous population. We speak to geographer Professor Harriet Bulkeley on why cities have such an important role in fighting climate change, what it means for a city to be sustainable and the big challenges that lie ahead. We look at the construction of zero-energy housing, homing in on the case of Nottingham, UK, and find out how scientists are putting nature back into the old Spanish capital of Valladolid. We also talk to the city officials breathing new life into historical buildings in Bologna, Italy, and learn how urban planners and architects are taking emotional feedback into account when designing new public spaces and homes.
How can science help refugees to successfully make a new home in Europe? In July, Horizon examines what we mean when we talk about integration and how research can help refugees build a better future. We speak to Dr Dominik Hangertner at ETH Zurich, Switzerland, about defining integration in order to measure it, the impact of current asylum policies and how big data can help resettlement decisions. We examine how researchers are looking into specific programmes that schools can establish to support adolescent refugees and how media literacy is one such area that can empower young newcomers. We also look at how longer-term mental health needs are being addressed and we speak to researchers and scientists who came to the EU as asylum seekers about the challenges of starting over in a new country.
The so-called second quantum revolution is in full swing, with scientists not only able to understand what happens at a sub-atomic level but also control this quantum behaviour enough to develop new technologies. Six months after the launch of the EU’s €1 billion quantum flagship initiative to kickstart a European quantum technologies industry, we take a look at the potential of quantum to revolutionise our future. We speak to one researcher who is helping to build a quantum computer about the global race to do this and how Europe is faring. We take a look at the threat and promise of quantum technologies in the field of cryptography and find out how quantum simulators can be used to solve non-quantum problems. And finally, we speak to the scientists who are using quantum mechanics to improve the performance of brain scanners and better diagnose medical conditions.
How did European eating habits go so wrong? We have a plentiful supply of fresh food yet, according to Eurostat, one in every two people in Europe is either overweight or obese, leading to problems such as cardiovascular disease, high blood pressure and lifestyle-related diabetes. In May, we delve into the complex science of healthy eating to understand how to tackle modern-day malnutrition. We speak to public health expert Knut-Inge Klepp about the complex factors determining food choice and how to improve the diet of teenagers. We find out how scientists are working to improve the zinc content of crops to prevent the ‘hidden hunger’ of micronutrient deficiency and look at the importance of widening the diversity of grains that we eat – both for our health and for the environment. We also explore what’s behind the nutritional self-sabotage of eating disorders.
As May’s European elections approach, Horizon takes a step back to see what science can tell us about European politics. We look at the latest research into people’s opinions about the EU and how they’ve changed, particularly in response to the financial crisis of 2008, and ask what needs to be done to bring the public closer to politicians. We speak to cryptography expert Dr Steve Kremer about why most of us can’t vote online yet, and democracy specialist Prof. Wolfgang Merkel about the changing political party structures in Europe and whether this is a threat to democracy. We also find out how scientists are working to detect and flag fake news on social media in order to increase the transparency of the information people encounter online.
This month, Horizon explores the global challenge of biodiversity loss. Many experts believe we are in the midst of a sixth mass extinction, where human-caused factors such as land use and pollution are causing a decline in biodiversity – something that threatens the future of our own species. We speak to British ecologist Professor Georgina Mace about how bad the situation is and what we can do about it. We explore marine ecosystems, where species relocation outpaces that of terrestrial populations, and examine how we can help these environments adapt, as well as finding out what’s in store for bees – our pollinators. Finally, we investigate the services nature provides for people – from cleaning our water to acting as a carbon sink – and ask whether putting a value on natural capital could help save it.
Fifty years after humans first set foot on the moon, Earth’s only permanent natural satellite is back in the news with China’s successful landing on the moon’s as-yet-unexplored far side. This month, Horizon looks at how Europe is contributing to moon research. We hear from the European Space Agency’s director of human and robotic exploration about their plans to send a robot and then humans to the lunar surface in the 2020s, and speak to the scientists trying to fill the holes in our understanding of how the moon was formed. We also hear how we could solve the puzzle of where water on Earth originated by analysing volatile substances from the moon, and take a look at the methods and facilities being developed to protect precious extra-terrestrial samples from human contamination.
The languages we speak and how we speak them are an integral part of our identity, shaping not only how we see the world but also how people see us. In January, Horizon puts language under the spotlight, kicking off the month with a look at Europe’s minority languages and how to preserve them. We also delve into the social and cognitive aspects of language use, finding out how accents arise and how they affect people’s perception of the speaker, and discovering how ageing affects linguistic capacity in bilingual people – and vice versa. We also speak to researchers looking into the language impairment dyslexia and potential options for early diagnosis.
When it comes to climate change, it is often said that what happens in the Arctic does not stay in the Arctic. This month, with the COP24 UN climate change conference taking place in Katowice, Poland, Horizon looks north to the region of the world that is feeling the effects of global warming most acutely. We speak to Marianne Kroglund from the Arctic Council about whether it is too late to save the fragile ecosystems there and examine how studies of ice melt show that the world may still have a fighting chance of limiting sea level rise. We find out how the Arctic environment could be protected in the face of increased maritime traffic and look at the effect of melting permafrost – soil, sediment or rock that’s been frozen for at least two years – on the environment and local communities.
In its landmark report in October, the UN's International Panel on Climate Change said that every package of measures we choose to limit global temperature rises to 1.5°C must include a way of removing carbon dioxide emissions from the air and reusing or storing them. This month, Horizon looks at what's being done to advance these carbon capture, storage and utilisation technologies. We talk to one expert who is trying to trap emissions from the cement industry before they are released, and find out how International Space Station technology is inspiring the capture of ambient carbon dioxide. We also investigate how captured CO2 can be reused, and examine just how safe it is to store the gas underground.
