It's a tricky business, since biosignatures based on single measurements of atmospheric gases could be misleading.
Microbes used to convert human waste into space food
The team found that methane was readily produced during anaerobic digestion of human waste and could be used to grow a different microb.
New catalyst developed to recycle carbon dioxide and methane
It is hoped the new catalyst will help make the technology more widely available across industry.
