In November, Horizon discovers a futuristic world of transparent e-books, plastic solar cells and electronic skin with a look at some of the applications of organic electronics. We speak to organic chemist Prof. Andreas Hirsch about how using carbon rather than silicon in electronics can make them flexible, lightweight and biocompatible and could lead to a new generation of human-looking robots and ‘chemical’ computing. We take a look at work to create electronic skin – self-healing, stretchable material that can mimic some of the functions of human skin – and its potential uses. We discover how thin, flexible, plastic solar cells could turn surfaces such as cars and fabric into sources of renewable energy, and we uncover some novel approaches to charging wearable electronics.
The world looks very different from this time last year. The coronavirus pandemic has highlighted the centrality of science, research and innovation, accelerated some changes already in the works, but also exposed our weaknesses. In September, Horizon looks at how the pandemic is reshaping Europe in areas including health research, work, tech, transport and food – and how research can contribute to Europe’s recovery over the coming years. We will also be covering the European Research & Innovation Days at the end of the month, which will bring together scientists, policymakers, entrepreneurs and citizens to debate how research and innovation can ensure that the transition to a post-coronavirus society is sustainable, inclusive and resilient.
In August, Horizon looks at one of the features that makes Earth unique and habitable: plate tectonics. We explore what we know – and still don’t know – about how the shifting plates beneath our feet shape our planet. We speak to researcher Dr Kate Rychert, who wants to understand what makes a plate plate-like, and delve into one of the outstanding mysteries in the subject – how and why plate tectonics began. We find out about the link between mountain formation, erosion and climate change, and we look at what moonquakes and marsquakes can reveal about tectonic activity elsewhere.
As commutes dropped during coronavirus lockdowns, many of Europe’s city-dwellers breathed cleaner air. In July, Horizon takes a look closer look at our air pollution problem, what it is, how it affects human health and whether now is the time to make the move to greener transport. We spoke to social epidemiologist Dr Basile Chaix about what it will take to capitalise on the post-coronavirus calls for greener cities to really change our urban spaces – and transport habits. We dissect the properties of particulate matter to understand how characteristics such as particle size or number relate to toxicity, and what they do to human cells. With wildfires known to strike particularly in the summer, we look at how scientists are tracking this lesser-known source of air pollution to better understand the impact on human health. And we find out how a soybean-related asthma outbreak in 1980s Spain is influencing air pollution research today.
In June, against a backdrop of the coronavirus pandemic, a climate emergency and an uncertain future, Horizon takes a look at anxiety. Are we becoming more anxious? What do we really know about the condition and who suffers from it? And how can we best treat it? We speak to anxiety disorder expert Professor David Baldwin about when anxiety turns from a normal response into a long-term problem and what we know – and don’t – about why this happens. We take a look at one particularly vulnerable group – teenagers – to understand how anxiety affects them and how they can best be treated. We explore the link between anxiety and our awareness of bodily sensations to understand, for example, why breathing can calm the mind, and we also talk to the researchers who believe the key to improving anxiety therapies is to look at how different people respond when under threat.
By 2050, the world's population will be an estimated 9.7bn people, up from today’s 7.7bn. To feed this growing population whilst also protecting the climate and biodiversity, our food system needs to change dramatically. In May, we look at what sort of future food system we want and how to get there. We speak to sustainability expert Prof. Peter Jackson about how lockdowns have exposed our reliance on fragile supply chains, and what needs to happen to shape a more sustainable food system. We look at the smart farming solutions that are being explored to support food producers, and urban experiments from tackling food waste to strengthening organic, local production to see how these efforts can be scaled up to make a big difference. And we investigate insects – a protein-rich food and feed source – and the efforts behind mainstreaming what is still a niche science.
With the world in the grip of the coronavirus pandemic, in April Horizon takes a step back to look at some of the challenges around sudden outbreaks of emerging diseases. We speak to virologist Prof. Marion Koopmans about the likelihood of future outbreaks of new diseases, what causes them and how to spot them before they appear. We speak to scientists who are helping to develop tests for Covid-19 to understand the challenges in coming up with an accurate and detailed diagnostic test for an entirely new disease. We talk to people working on coronavirus treatments about how to shorten the normally lengthy process of drug development. And we look into why diseases suddenly jump from animals, such as bats, into humans and the particular challenges of spotting and responding to these types of outbreaks.
Private companies are increasingly active in the space sector – from high-profile businesses such as SpaceX or Virgin Galactic to the nearly 3,000 small businesses that provide elements for the European Space Agency’s space programme. In March, Horizon explores the impact of this on research and innovation. We speak to a space law researcher about how to avoid the problems emerging from an increasingly crowded orbit, such as collisions. We look at how to minimise the environmental impact of satellites and delve into efforts to build a reusable European launcher for small payloads. We also look at the challenge of assembling, maintaining and repairing objects in space and the developments in space robotics that could help.
More than 30% of car journeys in Europe are under 3km long and could potentially be swapped for different, greener, forms of transport. In February, we look at alternative ways of getting people and goods around cities - a challenge known in the industry as the problem of the ‘last mile’. We speak to Karen Vancluysen of cities network POLIS, who says that cities may have to introduce some unpopular measures to change the way people move around, and we look at how soon commuters will be able to rely on automated shuttles to ferry them from door to door. We delve into the environmental problems caused by unsuccessful home deliveries and what can be done about them, and the new technologies that could change the way goods are delivered.
In January, we examine how the cryosphere - ice sheets, glaciers, sea ice and other frozen parts of the planet - is changing and what this means for our planet. Earth’s cryosphere reflects the sun’s heat, regulating climate. But as the cryosphere melts, sea levels are rising and there are other impacts too – such as glacier collapse, which can generate massive avalanches. We speak to glacier expert Professor Andreas Kääb about the current state of the planet’s ice and snow and how better satellite measurements can help us understand the impacts of melting. We look at Earth’s so-called 'third pole’ of the Tibetan plateau and how ice melt will affect the millions who live in the mountains and those who depend on its run-off for water. We look at a project drilling in the Antarctic for what could be the world’s oldest ice (1.5 million years old) to see what it can reveal about climate history. And we speak to sea ice scientist Polona Itkin to get a glimpse into a day in her life aboard German icebreaker Polarstern, currently carrying out the largest Arctic expedition in history.
Scientists are studying past conditions to understand which corals migrated to deeper waters.
A lack of knowledge about thunderstorms means we could be overengineering our tallest buildings.
Dr Kate Rychert studies ocean plate structures.
