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.
Rye bread or porridge oats may not be everyone’s first choice of breakfast, but scientists say Europeans need to broaden their taste in cereals both to boost their own health and to protect the future of Europe’s farming.
Teenagers rarely have a say in the public health policies that concern them, but we can’t halt the childhood obesity problem without working with them, says Professor Knut-Inge Klepp, executive director of the mental and physical health division at the Norwegian Institute of Public Health.
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.
The iridescence of marble berries and the clever, light-bending perforations of microalgae are some lessons from nature that scientists are drawing upon to create biodegradable glitter and makeup pigments, and bionic algae to use in lasers or to clean pollutants.
Efforts to design a safe vaccine for Covid-19 are moving forward at full throttle, yet experts agree that it’s likely to be a year, at least, before an immunisation is ready. Meanwhile, scientists around Europe are exploring ingenious ways – including with the help of alpacas – to use the latest techniques in molecular manipulation to repair coronavirus-induced lung damage or to block the virus before it wreaks havoc.
Scientists are drawing on nature’s clever ways to build structures and produce iridescence.
Infection-halting therapies being explored include neutralising antibodies.
Metagenomics can help us spot emerging diseases such as coronavirus, says virologist Marion Koopmans.
