The Animated Nitrogen Cycle
This animation of the biogeochemical nitrogen cycle illustrates the main steps of the cycle in air, water, and soils. The video explains and connects the many forms of nitrogen, such as ammonia, ammonium, hydroxylamine, nitrite, nitrate, nitrous oxide, and nitrogen dioxide, and explains the role of nitrate in nitric oxide signaling in the human body.

Paul Hsieh and The Deepwater Horizon Oil Spill
In April of 2010, Paul Hsieh, a research scientist, readily stepped up to an opportunity to provide a service to the public that pulled him away from his work, that pulled him out of his environment. This was not something that's in his job description, but it was a way for him to make a tangible contribution, and as it turned out, he made a significant difference.
