News: Ozone woes and junior doctor strikes – We discuss how the ozone layer may still be in trouble, and find out the impact of the 2016 junior doctors strikes on patients.

The health effects of being poor – Having a low socioeconomic status can cut up to seven years off your life and make your ‘biological age’ older than your real age. We find out what can be done to reduce the gap between health outcomes for the rich and poor.

Health inequality in global cities – The health gap between rich and poor is widening in cities, despite potential access to more and better services. For this potential to be reached, however, researchers say factors like affordable housing and quality food need to be addressed in cities across the world – from London to Accra.

Keeping the lights on in Cameroon – Countries near the equator have a lot of sunshine to take advantage of, but low-cost solar panels are a must. We catch up with a researcher collaborating with academics in Cameroon on cheap solar panels, and find out what he thought of the country on his first visit.
