Humans have introduced more than 37,000 alien species to places they do not naturally occur. A report launched this week by the Intergovernmental Platform on Biodiversity and Ecosystem Services revealed the shocking extent of the damage. Gaia Vince speaks to one of the report’s chairs, Helen Roy.

Also this week, the UK has now rejoined Horizon Europe, the EU’s £85bn flagship research funding programme. Gaia caught up with the Royal Society’s vice-president Linda Partridge to find out what this means.

Early this week, the Indian space agency, ISRO, launched its solar mission to study space weather. But in addition, its lunar mission, Chandrayaan-3, also powered down. Gaia speaks to Mahesh Anand, a planetary scientist at the Open University, to find out more about India’s space ambitions.

Meanwhile, here on Earth, many of us have been sweltering in heatwave conditions and communicating weather dangers have become a key focus for forecasters. Helen Roberts, the Met Office’s first ever sociometeorologist, explores how cognitive biases affect our responses to warnings.
