The state of our substrate: What is drought doing to our soil?

Large parts of Europe are in the grip of drought. According to the UK Meteorological Office, last week was the UK's driest July on record. Katie Field, professor of plant-soil processes at Sheffield University, joins us to discuss the state of our struggling substrate. Next week, a dramatic solar eclipse will be sweeping down the Atlantic. In the past, eclipses have been vital to astronomers exploring the outer reaches of the Sun. Now though, they can make their own on demand. Esther Bastida-Pertegaz, project engineer at the European Space Agency, discusses the flying formation Proba-3 mission. A highly pathogenic bird flu has arrived in Australia, threatening local wildlife. Every continent in the world is now affected, and the harm that could be done to bird populations and mammals could be devastating. Thijs Kuiken, virologist at Erasmus University Medical Center in Rotterdam, brings us up to date with the situation. And Lizzie Gibney of Nature Magazine joins us to discuss this week’s science news.
