Since the early 1950s, humans have produced more than 8.3 billion tonnes of plastic – the weight of around a billion elephants. About 60% of that plastic has ended up in a landfill or in the natural environment, according to the UN Environment Programme, but that pattern may start to change as repair and recycling technology gathers pace. ‘Worldwide, … Read more
A bird flaps its wings, glides using air currents and then smoothly descends to perch on a pole. But this is not just any bird, it’s a robot bird. And robots like these could in the next decade be used to respond to emergencies or to hunt down drones posing a threat to safety or … Read more
Trees, crops and even organic waste can be transformed into a bewildering array of plastics to use in products ranging from single-use bags to heavy-duty aeroplane wings. These so-called biopolymers could play a vital role in weaning us off petroleum plastics – which will help cut greenhouse gas emissions, and ensure plastics come from a … Read more
Common medicines that have passed through patients’ bodies are ending up in the environment, but the threat many of them pose to wildlife and human health still needs to be determined. It may even be possible to recover some of these life-saving compounds so they can be reused. Over the past two decades, there has … Read more
Harmful bacteria found in chickens that can cause food poisoning outbreaks and devastate poultry flocks could be better controlled with innovative new solutions being developed by researchers. Bacterial infections are a major problem for poultry producers. Outbreaks of E. coli, for example, can spread quickly through a flock, resulting in high mortality and loss of … Read more
Tiny nano-sized robots and vehicles that can navigate through blood vessels to reach the site of a disease could be used to deliver drugs to tumours that are otherwise difficult to treat. Once injected or swallowed, most drugs rely upon the movement of body fluids to find their way around the body. It means that … Read more
