Gonorrhea. Bed bugs. Weeds. Salamanders. People. All are evolving, some surprisingly rapidly, in response to our chemical age. In Unnatural Selection, Emily Monosson shows how our drugs, pesticides, and pollution are exerting intense selection pressure on all manner of species. And we humans might not like the result.

Monosson reveals that the very code of life is more fluid than once imagined. When our powerful chemicals put the pressure on to evolve or die, beneficial traits can sweep rapidly through a population. Species with explosive population growth—the bugs, bacteria, and weeds—tend to thrive, while bigger, slower-to-reproduce creatures, like ourselves, are more likely to succumb.

Monosson explores contemporary evolution in all its guises. She examines the species that we are actively trying to beat back, from agricultural pests to life-threatening bacteria, and those that are collateral damage—creatures struggling to adapt to a polluted world. Monosson also presents cutting-edge science on gene expression, showing how environmental stressors are leaving their mark on plants, animals, and possibly humans for generations to come. 

Unnatural Selection is eye-opening and more than a little disquieting. But it also suggests how we might lessen our impact: manage pests without creating super bugs; protect individuals from disease without inviting epidemics; and benefit from technology without threatening the health of our children.

"John Erni's heartfelt and insightful book is a valuable contribution to the study of the cultural politics of AIDS."–Jeff Nunokawa Princeton University

The "cure" for AIDS: The search goes on, keeping pace with our belief that AIDS is incurable. How such a seeming paradox works-and how it may well work against the proper treatment of the disease-is the subject of Unstable Frontiers, a probing, critical look at the cultural politics behind the quest for a cure for AIDS.

This massive commercial and scientific project, John Erni suggests, actually hinges on our contradictory definitions of the disease as curable and incurable at the same time. Drawing on diverse sources, from popular media to medical literature to cultural theory, he shows how the dual discourse of curability/incurability frames the way we think about and act on issues of medical treatment for AIDS. His work makes a major advance in our understanding of—and, perhaps, humane response to—a national crisis.

In his critique of the logic and fantasies underlying the double definition of AIDS, Erni explores a broad range of issues: the scientific paradigm used to develop AZT; the politics of alternative treatment practices, of clinical drug trials, and of AIDS activism; and the notions of time and temporality operating in AIDS treatment science. He also addresses the problematic popular themes, such as "AIDS is invariably fatal" and "Knowledge = Cure."

Unique in its approach to a social and political issue still in the making, the book reveals how AIDS has challenged technomedicine's historical position of authority-and in doing so, recasts this challenge in a powerful and ultimately hopeful way.

John Nguyet Erni is assistant professor of communication at the University of New Hampshire. He has published essays on AIDS and is currently working on a book about AIDS in Thailand.
