I’m not saying I needed space… but I took it literally Apparently Earth wasn’t enough for me. (Yes, the ticket is fake. The obsession is real.) A real reminder that microbiology is increasingly moving from Earth to space, from extremophiles and One Health to planetary resilience.

Lignocellulose-mediated selection of potential halophilic PET-degrading enzymes from mangrove soil - Nature Communications
Mangroves are increasingly exposed to plastic pollution. In this study, the authors performed microcosm experiments to show that mangrove soil microbial communities are reshaped by lignocellulose inputs yielding potential halophilic PET-degrading enzymes as promising candidates for plastic degradation.
