The arousal effects the researchers measured are equivalent to about half a cup of coffee, and many other factors in a person's surroundings will affect a night's sleep as much or more than cell phone transmissions.

The psychogeography of the United States? According to this article, various personality types shows distinct regional clustering:

...America's psychogeography lines up reasonably well with its economic geography. Greater Chicago is a center for extroverts and also a leading center for sales professionals. The Midwest, long a center for the manufacturing industry, has a prevalence of conscientious types who work well in a structured, rule-driven environment. The South, and particularly the I-75 corridor, where so much Japanese and German car manufacturing is located, is dominated by agreeable and conscientious types who are both dutiful and work well in teams.

The Northeast corridor, including Greater Boston, as well as San Francisco, Los Angeles, Seattle, and Austin, are home to concentrations of open-to-experience types who are drawn to creative endeavor, innovation, and entrepreneurial start-up companies. While it is hard to identify which came first - was it an initial concentration of personality types that drew industry, or the industry which attracted the personalities? - the overlay is clear.

"Hard Drive Recovered from Columbia Shuttle Solves Physics Problem":

Researchers have finally published the results of data recovered from a cracked and singed hard drive that fell to Earth in the debris from the Space Shuttle Columbia, which exploded during reentry on February 1, 2003, killing all seven crewmembers.

The hard drive contained data from the CVX-2 (Critical Viscosity of Xenon) experiment, designed to study the way xenon gas flows in microgravity. The findings, published this April in the journal Physical Review E, confirmed that when stirred vigorously, xenon exhibits a sudden change in viscosity known as shear thinning. The same effect allows whipped cream and ketchup to go from flowing smoothly like liquids to holding their shapes like solids.
