[Sci-tech-public] Monday, November 19: Hannah Landecker's colloquium, 4:00 pm @ MIT

[Debbie Meinbresse]

Please join us on Monday, November 19, for an STS colloquium 
co-sponsored with the History of Science Department at Harvard.

 From Messengers and Bodies to Signals and Cells:
Theories of Hormone Action, 1960-1975

Hannah Landecker, Rice University and Harvard University (Visiting)

4:00 p.m., MIT, E51-095*


In the 1960s, the concept of hormones as messengers that traveled 
from one organ to another in the body and acted on enzymes to cause 
physiological changes was gradually replaced by hormones as signals 
that traveled from one cell to another, and acted via the cellular 
mechanisms of receptors and gene transcription to cause a cascade of 
molecular events.  In particular, metabolic effects of hormones in 
the liver were a site of intensive work and debate about the 
mechanism of hormonal translation of environmental cues into bodily 
responses.  This story of the mechanism of hormone action is offered 
as an example of a larger history of the organism and its milieu in 
twentieth century biology: how the field of cell signaling or cell 
signal transduction moved to the center of our understanding of the 
mediating mechanisms between bodies and environments.

Hannah Landecker is an Assistant Professor in the Anthropology 
Department at Rice University, and in 2007-2008 Visiting Assistant 
Professor in the History of Science Department at Harvard.   She is 
the author of Culturing Life:  How Cells Became Technologies, 
published in 2007 by Harvard University Press.
