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.
How do you feed a city? It is one of the great questions of our time. After all, for a species that ultimately depends on plants to feed ourselves, we do tend to cram ourselves into places that are rather unfriendly towards them. Our cities are built around cars, offices and perhaps the odd park – not fields of crops.
Insects in products such as pasta or bread, microalgae, and single-cell proteins derived from wood could feed and nourish humans and animals in the future. Now, those exploring alternative proteins for more sustainable eating are working out how to make the switch to bug-based food a reality.
Europe urgently needs to make its food system more sustainable – or else face growing food insecurity and health impacts – and the coronavirus pandemic offers us an opportunity to push for change, according to Professor Peter Jackson.
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.
Bats are in the limelight these days because they are rumoured to be the source of SARS-CoV-2, the virus that caused the coronavirus pandemic. But that is just part of their story. Bats turn out to be miraculous creatures. Their ability to age without decrepitude or cancer, as well as fight off a multitude of infections, are giving us clues about how to do the same for ourselves.
Thanks to rapid computing developments in the last decade and the miniaturisation of electronic components, people can, for example, track their movements and monitor their health in real time by wearing tiny computers. Researchers are now looking at how best to power these devices by turning to the user’s own body heat and working with garments, polka dots and know-how from the textile industry.
Bats stave off infections and ageing. What could humans learn from these abilities?
