In this study, Fackelmann et al. show that microplastics impair the gastrointestinal microbiome of two seabird species.

Vincent et al. investigate the impact of viral infection on the microbial communities of algal blooms and carbon cycling.

A study on a marine bacterium shows that it can form multicellular aggregates, which enable division of labour.

The COVID-19 pandemic has encouraged scientists and the general population to think more than ever before about how we interact with microbes in our indoor spaces. Research investigating transmission of SARS-CoV-2 has advanced our knowledge significantly in the last two years. However, indoor and built environment microbiomes are extremely complex polymicrobial systems. We have barely scratched the surface in our understanding of the microbial inhabitants of our indoor and urban spaces. The Microbes in the Built Environment Collection showcases recent research in this important topic around the globe.

Humankind relies on host–microbe symbioses and the ecosystems they form for diverse services, including food and health. It is important to understand how symbioses will fare in a world facing rapid global change and how adaptation and resilience of symbioses can be aided to secure their services for future generations.

Cyanobacteria, which produce ~25% of global oxygen, also release around 100 times more hydrocarbons into the ocean than all petroleum sources. A cryptic microbial cycle explains why these hydrocarbons do not accumulate in the sea.
