General Information

We contend that the phenomenon known as endocrine disruption is a manifestation of a larger biological issue ­ that is, the complex signaling networks that exist within and between organisms. These signaling networks can be maintained or perturbed by environmental factors. At e.hormone we intend to develop the tools for a new science of environmental signaling and introduce participants to the Environmental Signaling Network (an NSF-sponsored activity).

Themes of the meeting are:
1) environmental systems biology
2) fetal and childhood patterning, and
3) hormones and pharmaceuticals in water.

sponsored by the National Science Foundation at the Pere Marquette Hotel
9:00 - 1:00 pm Environmental Signaling 101: the Basics of Endocrine Disruption (ES 101)

ES 101 will provide a fundamental understanding of the principles underlying endocrine disruption. The goal of this workshop is to make complex issues understandable and useable. This day of activities is free; we hope to attract the interactive participation of curious, environmentally concerned teachers and students. Course instructors are leading researchers in their areas of inquiry as well as expert communicators. The course will be presented in three 50-minute modules followed by faculty-guided discussion/activity groups.

Instructors: John McLachlan (Tulane University), Lou Guillette (University of Florida, Gainesville), Cindy Gulledge (University of Louisville), Tyrone Hayes (University of California, Berkeley), William Toscano (University of Minnesota), Thomas Wiese (Xavier University)
1:00 - 2:00 pm lunch
2:00 - 4:00 pm ES 101 Curriculum Discussion and Development

This important feedback session will be devoted to critically analyzing ES 101. The goal is to refine course information and instruction and to create methods for curricular adaptation, dissemination, and implementation. ES 101 attendees are asked to participate.

Workshop Session I – Developmental Estrogenization Syndrome (at hotel)
  Through this provocative and enlightening exercise we will seek to create a hypothetical model for developmental induction of adult health and disease.

Panelists will include, epidemiologists, molecular biologists, developmental systems biologists, consumers, clinicians, ecologists, and experimental biologists.
Workshop Session II – Environmental Signaling: An Intersection of the Arts, Humanities, & Science (at hotel)
  This workshop will address a two-fold issue:
  1. is environmental signaling a good metaphor in which to help art, science, and the humanities meet?
  2. what can such convergence create that can not be generated independently?
Panelists will present philosophic, personal, movement, & sculptural perspectives.
