Did you know there are 200 million insects for each human on the planet? This October, Horizon delves into the mysteries of this diverse set of creatures and their seemingly infinite survival skills. We talk to researchers about why it's vital to maintain the diverse range of insect species, find out how robots and ants can work together to solve problems and explore how the superpowers of bugs could be put to use for humans.
Herbivorous insects are estimated to be responsible for destroying one-fifth of the world's total crop production annually, but a new, natural approach to pesticides that turns insects' taste and smell preferences against them could help reduce this toll.
Insects have to cope with a wide range of environmental factors in order to thrive – disease, drought and habitat changes. Scientists hope that studying insect biology and behaviour could help humans cope with problems from climate change to disease control, shift work and even jet lag.
To many people, they are merely creepy-crawlies to be swatted away or avoided, but the planet we live on is dominated and run by insects, argues Professor Alexey Solodovnikov, curator of the beetle collection at the Natural History Museum of Denmark. He believes more must be done to understand and protect this hugely diverse group of animals.
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.
Raising children can be a tough job, especially when doing it alone, but some animals like meerkats and mongooses work together to raise their young. Studies of these cooperative creatures are revealing how this highly social behaviour evolved and is shedding light on the roots of our own species’ collaborative abilities.
From a chemical-free spray that turns sand into lush green land, to a caterer who serves planet-friendly dishes, and from technology that makes stronger concrete with less cement, to insect farms that produce fish food and fertilisers, there is no shortage of ideas to reduce emissions. But which ones work best?
Their collective nurturing may explain how humans learned to work together.
A new global scoring system helps identify solutions that will drastically cut emissions.
Test flights have shown promising results – Dr Chong Cheng Tung.
