World Economic Forum (July 15, 2023) – This week’s top stories of the week include:

0:15 UK universities have a plan for AI – The guidelines aim to incorporate AI ethically into education and treat it as ‘an opportunity rather than a threat’. The UK’s 24 Russell Group universities are signing the principles.

2:07 This trolley can spot if you’re at risk of stroke – It has electrocardiogram (ECG) sensors embedded in its handles which screen you for heart irregularities as you shop. Researchers at Liverpool John Moores University fitted the sensors into 10 trolleys and rolled them out at 4 supermarkets in Liverpool, UK. Shoppers were invited to hold the handlebar for at least 60 seconds. If the sensor didn’t detect an irregular heartbeat, it lit up green. Over 2 months, the trolleys screened 2,155 people. They detected atrial fibrillation in 39 people who were swiftly able to book a cardiologist appointment.

3:50 Paris generates clean energy from Métro passagers – Energy firm IBERDROLA converted 6 turnstiles into mini-turbines at Miromesnil Métro station for 2 days last year. As each passenger passed through the turnstiles the turbines converted their movement into green energy. 27,000 passengers used the turnstiles. Each passenger generated 0.2 watts of energy. If scaled across the entire Métro system, which serves 1.5 billion passengers annually this technology could generate 136MW per year.

5:09 These sensors can spot stressed tomatoes – Their inventors say they can make agriculture more sustainable while increasing crop yields at the same time.
