An international team including a University of Washington scientist has found that the water on one of Saturn’s moons harbors phosphates, a key building block of life. The team led by the Freie Universität Berlin used data from NASA’s Cassini space mission to detect evidence of phosphates in particles ejected from the ice-covered global ocean of Saturn’s moon Enceladus. Phosphorus, in the form of phosphates, is vital for all life on Earth.

Ecologist Aaron Wirsing discusses his research in both terrestrial and aquatic systems, the ways that top predators, such as grey wolves and tiger sharks, shape their ecosystems and how humans affect predator-prey interactions through processes such as urbanization and climate change. Wirsing is a professor with the School of Environmental and Forest Sciences studying predator-prey interactions. He is also Principal Investigator of the Predator Ecology Lab, which seeks to better understand how predators influence their surroundings by interacting with their prey, and endeavors to find solutions to the challenges of large carnivore conservation and management in the changing world.
