Joining forces: The role of the natural and social sciences in addressing the Global Nitrogen Problem

A wealth of scientific knowledge exists on the role of nitrogen in the natural and agricultural world, with research dating back over a century. Nitrogen sustains life and has enabled modern food production to keep up with the demands of the growing human population. However, we have reached a critical state where the use of synthetic nitrogen needs to be regulated due to the multitude of environmental impacts. The problem is that the effect nitrogen has on the planet is rarely discussed outside of scientific circles. With the recent development of international campaigns to address the global nitrogen problem, it’s time to put nitrogen research into practice with the help of social science.

How do kelp forests change water conditions and microbial communities?

In honor of World Algae Day which is celebrated on October 12th, we cover a recent study on charismatic kelp forest in the Pacific Northwest. A study led by Cathy Pfister at the University of Chicago shows that kelp forests can change water conditions by locally decreasing pH which can benefit organisms with shells. Furthermore, kelp forests increase the diversity of microbes, which may have previously overlooked consequences for nutrient cycling.
