Constructed wetlands do a good job in their early years of capturing carbon in the environment that contributes to climate change – but that ability does diminish with time as the wetlands mature, a new study suggests.

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. 

A new project to address vulnerabilities in the UK’s food supply chain – and protect the country from potential shortages – has been launched thanks to funding from UK Research and Innovation (UKRI).

The £2 million initiative is building on recent research that found over 40% of food experts believe widespread civil unrest linked to food shortages, such as demonstrations and violent looting, is possible or likely in the UK within the next 10 years.
