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.
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.
Eavesdropping on the shudders and groans echoing deep inside alien worlds like Mars and the moon is revealing what lies far beneath their surfaces and could teach us more about how our own planet formed.
More than six months into the coronavirus crisis, data show that not just age, but also biological sex plays a pivotal role in the manifestation and response to Covid-19, with more men dying from acute infections versus women in the short term. This discrepancy has shined a spotlight on a key theme that has gained traction in recent years: is enough being done to account for sex and gender in disease and medicine? Not enough, says Dr Sabine Oertelt-Prigione, the chair of sex and gender-sensitive medicine at Radboud University in the Netherlands and a member of the European Commission’s expert group on gendered innovations.
Earth is not the only place in our solar system that shakes with seismic activity.
