In a recent New York Times article the newspaper’s senior science writer, William J. Broad, takes a dig at Republican presidential candidate Newt Gingrich’s obsession with the possibility of a “nightmarish of doomsday scenarios: a nuclear blast high above the United States that would instantly throw the United States in a dark age.”

The phenomenon that Gingrich refers to is an electromagnetic pulse (EMP), one side effect of a nuclear explosion. EMPs can destroy or disrupt virtually anything electrical, from computers to power grids. As the Times points out, Gingrich has used this potential threat to advocate bombing Iran and North Korea. “I favor taking out the Iranian and North Korean missiles on their sites,” he told the American Israel Public Affairs Committee in 2009. Gingrich has also talked up the EMP “threat” on the campaign trail.

Broad dismisses EMPs as “a poorly understood phenomenon of the nuclear age” and quotes Missile Defense Agency spokesman Richard Lehner poo-pooing the damage from an EMP attack as “pretty theoretical.”

While the Times is correct in dismissing any Iranian or North Korean threat—neither country has missiles capable of reaching the U.S., Iran doesn’t have nuclear weapons, and both have never demonstrated a desire to commit national suicide—what Broad does not mention is that the effects of EMP are hardly “poorly understood”: the U.S. has an “E-bomb” in its arsenal. -more-

For eighty years, Americans have feared robots, worrying they might one day rule the world. In 2011 we realized our real enemies are not robots, but multinational corporations, who have declared war on democracy. -more-

It’s been a long time coming, but the Alameda County Breeding Bird Atlas is finally available from Golden Gate Audubon. Based on intensive fieldwork in the 1990s, this book is a splendid addition to the shelf of Bay Area atlases. So far we have Marin, Sonoma, Napa, Contra Costa, Santa Clara, and now Alameda. I believe a Solano project is in the works. A San Francisco atlas would be slender, but perhaps surprising. How about it, Audubon? -more-

Fluoride is the name given to a group of compounds that are composed of the naturally occurring element fluorine and one or more other elements. In the early 1940s, scientists discovered that people who lived where drinking water supplies had naturally occurring fluoride levels of approximately 1.0 part fluoride per million parts water (ppm) had fewer dental caries (cavities). More recent studies have supported this finding. Fluoride can prevent and even reverse tooth decay by enhancing remineralization, the process by which fluoride “rebuilds” tooth enamel that is beginning to decay. In 1945, Grand Rapids, Michigan adjusted the fluoride content of its water supply to 1 ppm and thus became the first city to implement community water fluoridation in a public water system. -more-
