The Yangtze River Estuary is a hotspot for nitrogen activity. Human actions have led to a surge in nutrients flowing into this area, disrupting the natural nitrogen cycle. Two crucial processes in this cycle are nitrification and nitrogen uptake. These processes have not been studied together much in estuaries until now. Scientists used special techniques to track t...

The ocean is full of tiny heroes that help keep life going on Earth. These heroes are bacteria that can turn nitrogen from the air into a form that plants can use. For a long time, scientists thought that only certain types of bacteria, like cyanobacteria, could do this in the ocean. But guess what? There are other types of bacteria, called heterotrophic bacteria, th...
