The Barents Sea is a wild, dark, stormy old ocean. Who would want to be out there on a ship in January?

We could be encouraging antimicrobial resistance by overusing antibiotics but other factors may also be at play. We spoke to researchers going beyond the clinic to understand how drug-resistance builds up in the bacteria in our sewers and rivers.

These days we can get a prescription for many infections, but what happens when you have more than one at a time? Emily Griffiths explains how we can look at co-infection in a way that could help us devise more effective treatments.

This week in the Planet Earth podcast, Elizabeth Wellington and Greg Amos of the University of Warwick explain how sewage treatment could be helping spread highly drug-resistant bacteria around the environment.

Wastewater treatment plants could be unwittingly helping to spread antibiotic resistance, say scientists.

This week in the Planet Earth podcast, Helen Hoyle of the University of Sheffield and Jim Harris from Cranfield University describe what a strip of land in Luton, southeast England, is doing for urban biodiversity.

Some scientists may dream of the chance to pursue their research on another planet. That opportunity isn't a reality just yet, but PhD student Michaela Musilova got the next best thing - a simulated mission to Mars.
