Meeting the Challenges of Great Lakes Stewardship Conference

On March 27 - 28, Case Western Reserve University will be hosting a conference entitled "Meeting the Challenges of Great Lakes Stewardship." This conference will be attended by faculty, students, and community members from virtually all of the Great Lakes states as well as Quebec. The goal of the conference is to create a vibrant network committed to long-term stewardship of the Great Lakes ecosystem by an informed and engaged citizenry. For more information about the conference, visit the SENCER website

The Conference is co-sponsored by The Midwest Center for Innovation of SENCER (Science Education for New Civic Engagements and Responsonsibilities) and CLEAN (Collaborative Learning for Environmental Action Network) of the Western Reserve Resource Conservation and Development Council.

How Could the Earth's Core Leak? by Dr. David Walker, Lamont-Doherty Earth Observatory

Abstract: The formation of the core produced a prodigiously stable
physical and chemical arrangement early in Earth history.
And yet there are a few suggestions that the process is
now running slightly backwards. The phase equilibria that
might help understand the process are sketchy at best.
Attempts to uncloud these equilibria and light element
solubilities in liquid metals at very high pressures are
