Episode notes

Togo, a west african nation of around eight point five million people was just one of many countries that was facing a crisis here. Citizens were facing the prospect of hunger and malnutrition. As the pendemic closed down the world, the togales government wanted to do as much as it could to help the most vulnerable. Government officials from togo reached out to josh bloominstock, a computer scientist based at the university of california berkeley who has had previous experience using machine learning to identify people in poverty. Next up, reportra nick pertridge. How has been finding out how machine learning helped the government of togo.

00:45 A flexible, wearable, fabric microphone

Inspired by the ear, a team of researchers have developed an acoustic fibre that can be woven into fabrics to create a sensitive microphone. This fabric microphone is capable of detecting human speech and heartbeats, and the team think it could be used to develop new, wearable sensors for long-term health monitoring.
