Polar bear fur’s natural ability to resist ice formation could pave the way for safer, more sustainable solutions to prevent ice buildup across industries such as aviation and renewable energy, according to researchers at the University of Surrey. 

A study assessed the impact of electric fans on the body core temperature and heart rate of 18 participants aged 65-85 years, who were exposed to a simulated extreme indoor environment of 36°C with 45 per cent relative humidity for eight hours. The results showed participants were unaffected by fan use, with all three of the experimental conditions resulting in an average body core temperature of 38.3°C and heart rate of 100 beats per minute.
