From a well-timed recyclable PPE glove to a wheel-based device to cut "invisible" pollution from tyres, 20 groundbreaking designs by students across the world are in the running to be named on Thursday as the international winner of the annual James Dyson award. The prestigious accolade brings with it a £30,000 cash prize – and gives winners a chance to turn their innovation into a commercial product with real-world impact. One in five previous winners have gone on to commercialise a wide range of exotic inventions, including bionic arms, origami-style clothing and bio-reactive food labels. For this year's award, a record 1,798 entries have been submitted – two-thirds more than last year – with a majority addressing urgent global issues such as climate change, sustainability, medicine and healthcare. This year's entries opened in March amid the deepening coronavirus pandemic.
