Microplastics in the mud: Finnish lake sediments help us get to the bottom of plastic pollution

The sun is shining, and air feels surprisingly warm when we walk on a 35cm ice that covers a frozen lake in central Finland. The heavy sledges move nicely, because there is not much snow on the ice today. The journey isn't ...

Capturing carbon dioxide with electricity: A microbial enzyme inspires electrochemistry

Humans continuously emits greenhouse gases, worsening global warming. For example, carbon dioxide (CO2) accumulates dramatically over the years and is chemically very stable. Yet, some microbes capture CO2 using highly efficient ...
