In the 4th century BC, Aristotle proposed that earthquakes were caused by winds trapped in subterranean caves.

The UK appears to be embracing nuclear, a huge U-turn on government policy from just two years ago. Yet this seems to be going against the grain globally. Can nuclear help countries meet their commitments to the Paris treaty?

Cities the world over are struggling to improve air quality as scandals surrounding diesel car emissions come to light and the huge health costs of pollutants are better understood. Anthony Lambert reports

Diabetes is often thought of as a ‘western’ problem, one linked to the developed world’s overindulgence in fatty foods and chronic lack of physical activity. But with more than 400 million people affected globally, this disease is a global threat
